Holding

Clause (ii) of the first proviso to Section 54(3) is a substantive restriction, and Rule 89(5) is within the legislative intent and therefore not ultra vires, leading to affirmation of the Madras High Court’s decision.

Summary

The Supreme Court examined whether the first proviso of Section 54(3) of the Central Goods and Services Tax Act, 2017 imposes a substantive restriction on refunds of unutilised input tax credit (ITC) arising from an inverted duty structure, and whether Rule 89(5) of the CGST Rules, which limits the refund calculation to ITC on input goods, is ultra vires. The Court held that clause (ii) of the proviso is a restriction, not merely a condition of eligibility, and that Parliament validly confined the refund to cases where the credit accumulates because the tax rate on inputs (goods) exceeds that on outputs. Consequently, Rule 89(5) is consistent with the statutory scheme and does not exceed the power conferred under Section 164. The Court also affirmed that refund is a statutory right, not a constitutional entitlement, and that the rule‑making authority may frame formulas to implement the Act. The Madras High Court’s view was upheld, overturning the Gujarat High Court’s decision. The Court urged the GST Council to reconsider the formula for practical equity but declined to read down or rewrite the provision.

Issues considered

  • The nature of clause (ii) of the first proviso to Section 54(3) – whether it is a restriction or a condition of eligibility for refund of unutilised ITC.
  • Whether Rule 89(5) of the CGST Rules, which excludes input services from the refund calculation, is ultra vires Section 54(3).
  • The validity of the formula prescribed in Rule 89(5) for computing refunds in cases of inverted duty structure.
  • The constitutional validity of Section 54(3) and whether a right to refund exists under the Constitution.
  • The scope of the rule‑making power under Section 164 of the CGST Act in relation to Rule 89(5).

A     recognising an entitlement to refund, it is open to the legislature to
      define the circumstances in which a refund can be claimed – The
      proviso to s.54(3) is not a condition of eligibility but a restriction
      which must govern the grant of refund u/s. 54(3).
             Central Goods and Services Tax Rules, 2017 – r.89(5) –
B     Validity of formula prescribed in r.89(5) – Held: The formula is not
      ambiguous in nature or unworkable, nor it is opposed to the intent
      of the legislature in granting limited refund on accumulation of
      unutilized ITC – It is merely the case that the practical effect of the
      formula might result in certain inequities – Given the anomalies
      pointed out by the assesses, GST Council to reconsider the formula
C     and take policy decision regarding the same.
            Disposing of the appeals, the Court
            HELD: Construing the Proviso
             1. Sub-Section (3) of Section 54 begins, in its main part,
D     with the stipulation that a registered person may claim refund of
      any ‘unutilised ITC at the end of any tax period’. Whether we
      construe the first proviso as an exception or in the nature of a
      fresh enactment, the clear intent of Parliament was to confine
      the grant of refund to the two categories spelt out in clauses (i)
E     and (ii) of the first proviso. That clauses (i) and (ii) are the only
      two situations in which a refund can be granted is evident from
      the opening words of the first proviso which stipulates that “no
      refund of unutilised input tax credit shall be allowed in cases other
      than”. What follows is clauses (i) and (ii). The intent of Parliament
      is evident by the use of a double – negative format by employing
F     the expression “no refund” as well as the expression “in cases
      other than”. In other words, a refund is contemplated in the
      situations provided in clauses (i) and (ii) and no other. To put it
      differently, the first proviso can be recast, without altering its
      meaning to read that a refund of unutilised ITC shall be allowed
G     only in the cases governed by clauses (i) and (ii). Clause (i) deals
      with zero rated supplies without payment of tax. Explanation-1 to
      Section 54 clarifies that the expression ‘refund’ includes refund
      of tax paid on zero rated supplies on goods or services or both,
      or on inputs or input services used in making such zero-rated
      supplies. On the other hand, in the case of deemed exports,
H     Explanation-1 refers to a refund of tax on the supply of goods.
   UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                        171


Likewise in regard to domestic supplies, governed by clause (ii)         A
of the first proviso, the expression ‘refund’ means refund of
unutilised ITC as provided under sub-Section (3). With the clear
language which has been adopted by Parliament while enacting
the provisions of Section 54(3), the acceptance of the submission
which has been urged on behalf of the assessee would involve a
                                                                         B
judicial re-writing of the provision which is impermissible in law.
Clause (ii) of the proviso, when it refers to “on account of” clearly
intends the meaning which can ordinarily be said to imply ‘because
of or due to’. When proviso (ii) refers to “rate of tax”, it indicates
a clear intent that a refund would be allowed where and only if the
inverted duty structure has arisen due to the rate of tax on input       C
being higher than the rate of tax on output supplies. Reading the
expression ‘input’ to cover input goods and input services would
lead to recognising an entitlement to refund, beyond what was
contemplated by Parliament. [Para 69][253-G-H; 254-A-F]
       2. This Court must be cognizant of the fact that no               D
constitutional right is being asserted to claim a refund, as there
cannot be. Refund is a matter of a statutory prescription.
Parliament was within its legislative authority in determining
whether refunds should be allowed of unutilised ITC tracing its
origin both to input goods and input services or, as it has
legislated, input goods alone. By its clear stipulation that a refund    E
would be admissible only where the unutilised ITC has
accumulated on account of the rate of tax on inputs being higher
than the rate of tax on output supplies, Parliament has confined
the refund in the manner which we have described above. While
recognising an entitlement to refund, it is open to the legislature      F
to define the circumstances in which a refund can be claimed.
The proviso to Section 54(3) is not a condition of eligibility (as
the assessees’ Counsel submitted) but a restriction which must
govern the grant of refund under Section 54(3). [Para 70][254-G-
H; 255-A-B]
                                                                         G
      Constitutional Validity of s.54(3)
       2. Parliament while enacting the provisions of Section 54(3),
legislated within the fold of the GST regime to prescribe a refund.
While doing so, it has confined the grant of refund in terms of the
                                                                         H
172           SUPREME COURT REPORTS                     [2021] 15 S.C.R.


A     first proviso to Section 54(3) to the two categories which are
      governed by clauses (i) and (ii). A claim to refund is governed by
      statute. There is no constitutional entitlement to seek a refund.
      Parliament has in clause (i) of the first proviso allowed a refund
      of the unutilized ITC in the case of zero-rated supplies made
      without payment of tax. Under clause (ii) of the first proviso,
B
      Parliament has envisaged a refund of unutilized ITC, where the
      credit has accumulated on account of the rate of tax on inputs
      being higher than the rate of tax on output supplies. When there
      is neither a constitutional guarantee nor a statutory entitlement
      to refund, the submission that goods and services must
C     necessarily be treated at par on a matter of a refund of unutilized
      ITC cannot be accepted. Such an interpretation, if carried to its
      logical conclusion would involve unforeseen consequences,
      circumscribing the legislative discretion of Parliament to fashion
      the rate of tax, concessions and exemptions. If the judiciary were
      to do so, it would run the risk of encroaching upon legislative
D
      choices, and on policy decisions which are the prerogative of the
      executive. Many of the considerations which underlie these
      choices are based on complex balances drawn between political,
      economic and social needs and aspirations and are a result of
      careful analysis of the data and information regarding the levy of
E     taxes and their collection. That is precisely the reason why courts
      are averse to entering the area of policy matters on fiscal issues.
      This Court is therefore unable to accept the challenge to the
      constitutional validity of Section 54(3). [Para 81][261-E-H; 262-
      A-B]
F           Validity of Rule 89(5) of CGST Rules in exercise of the
      rule making power u/s.164 of the CGST Act
            3. Under Section 164(1), confers an express power on the
      Central Government to make rules for carrying out the provisions
      of the CGST Act on the recommendations of the GST Council. It
G     may be true that in certain specific statutory provisions, the Act
      recognizes, by using the expression ‘prescribes’, that rules may
      be framed for that purpose. But the converse cannot be assumed
      inferentially, by presuming that in other areas, recourse to the
      rule making power cannot be taken. By its very nature, a statutory
      provision may not visualize every eventuality which may arise in
H
   UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                      173


implementing the provisions of the Act. Hence it is open to the        A
rule making authority to frame rules, so long as they are consistent
with the provisions of the parent enactment. The rules may
interstitially fill-up gaps which are unattended in the main
legislation or introduce provisions for implementing the
legislation. So long as the authority which frames the rules has
                                                                       B
not transgressed a provision of the statute, it cannot be deprived
of its authority to exercise the rule making power. The wide
powers given under Section 164 of the CGST Act are only limited
by the provisions of the Act itself, in furtherance of which a rule
maybe framed. It is for this reason that the powers under Section
164 are not restricted to only those sections which grant specific     C
authority to frame rules. If such a construction, as assessee has
hypothesised, were to be acceptable, it would render the
provisions of Section 164 otiose. Thus, this Court finds that the
absence of the words “as may be prescribed” in Section 54(3)
does not deprive the rule making authority to make rules for
                                                                       D
carrying out the provisions of the Act. [Para 85][263-F-H; 264-
A-C]
      The Vires of Rule 89(5) vis-à-vis Section 54(3) of the CGST
Act
      4. The grievance however is that Rule 89(5) goes beyond          E
the “provisions of the Act” when in the garb of fixing a formula, it
restricts the refund of ITC to input goods by denying ITC of
input services. This is done by defining ‘Net ITC’ to mean ITC
availed of inputs. The gravamen of the challenge is that this
consequently ignores ITC relatable to input services. In other
words, the submission is that Rule 89(5) cannot be construed to        F
be a rule for carrying out the “provisions of the Act”. [Para
90][266-B-C]
      5. The second limb of the line of challenge is that even
though the rules are required to be recommended by the GST
Council this will not elevate them to the status of a law enacted      G
by the legislature. The submission which has been urged by
assessee proceeds on an underlying assumption which is that
Rule 89(5) by restricting the definition of Net ITC to mean ITC
availed on input goods is an affront to Section 54(3). It is on this
foundation, that it has been urged that a rule which is contrary to    H
174            SUPREME COURT REPORTS                       [2021] 15 S.C.R.


A     the statute cannot be saved merely on the ground that either (i)
      the rule has been laid before Parliament and is subject to its power
      of modification annulment or amendment; or (ii) the rule was made
      on the recommendations of the GST Council. The application of
      the second layer of the argument does not arise in the present
      case for the simple reason that Rule 89(5) in defining Net ITC to
B
      mean “input tax credit availed on inputs” does not transgress
      the statutory restriction which is contained in proviso (ii) of Section
      54(3). The challenge to Rule 89(5) as a piece of delegated
      legislation on the ground that it is ultra vires Clause (ii) of the
      first proviso to Section 54(3) is therefore lacking in substance.
C     As reasoned in the earlier part of this judgment, Clause (ii) of
      the first proviso is not merely a condition of eligibility for availing
      of a refund but a substantive restriction under which a refund of
      unutilized ITC can be availed of only when the accumulation is
      relatable to an inverted duty structure, namely the tax on input
      goods being higher than the rate of tax on output supplies. There
D
      is therefore no disharmony between Rule 89(5) on the one hand
      and Section 54(3) particularly Clause (ii) of its first proviso on
      the other hand. [Para 92][266-F-G; 267-A-B]
            The Validity of the Formula prescribed in Rule 89(5)
E           6. In view of this Court, the justification of the formula under
      Rule 89(5) given by the ASG to create a legal bifurcation is valid.
      In this context, it would be material to advert to the provisions of
      Rule 42. Rule 42(1) provides that the ITC in respect of input
      goods or input services which attract the provisions of sub-Section
      (1) or sub-Section (2) of Section 17 being partly used for the
F     purpose of business and partly for other purposes or partly used
      for affecting taxable supplies including zero rated supplies and
      partly for effecting exempts supplies shall be attributed for the
      purposes of business or for effecting taxable supplies in the
      manner which is indicated in the Rule. Sub-Section (1) of Section
G     17 provides that where the goods and services or both are used
      by a registered person partly for the purposes of any business
      and partly for any other purpose, the amount of credit shall be
      restricted to so much of the input tax as is attributable to the
      purpose of its business. Sub-Section (2) of Section 17 provides
      that where the goods or services or both are used by a registered
H
   UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                        175


person partly for effecting taxable supplies including zero rated        A
supplies under the CGST Act or under the IGST Act and partly
for effecting exempt supplies the amount of credit shall be
restricted to so much of the input tax as is attributable to the
taxable supplies including zero rated supplies. Rule 42, in other
words, provides for the manner in which the attributions of ITC
                                                                         B
in respect of the input or input services under sub-Sections (1)
or (2) of Section 17 shall be carried out. Rule 43 similarly provides
the manner in which ITC in respect of capital goods attracting
the provisions of sub-Section (1) of Section 17, used partly for
business and partly for other purposes or partly for effecting
taxable supplies including zero rated supplies and partly for            C
effecting exempt supplies would be attracted to the purpose of
business or for effecting taxable supplies. Both Rules 42 and 43
provide for a formula for attribution. Rule 86 provides for the
maintenance of an electronic credit ledger. Rule 89(5) provides
for a refund. In both sets of rule clusters, Rules 42 and 43 on the
                                                                         D
one hand and Rule 89(5) on the other hand, a formula is used for
the purpose of attribution in a post assimilated scenario. The use
of such formulae is a familiar terrain in fiscal legislation including
delegated legislation under parent norms and is neither untoward
nor ultra vires. [Para 103][271-G; 272-A-F]
      7. The aberrations which have been pointed out, certainly          E
indicate that the formula is not perfect. The formula makes a
presumption that the output tax payable on supplies has been
entirely discharged from the ITC accumulated on account of input
goods and there has been no utilisation of the ITC on input
services. While a similar formula is provided in Rule 89(4) with         F
regard to zero rated supplies, in that case, the ‘Net ITC’ includes
input goods and input services and thus, there is no imbalance
between the different components of the formula. The formula
prescribed in Rule 89(5) however, seeks to deduct the total output
tax from only one component of the ITC, namely ITC on input
goods. This in our view is at odds with reality, where the ITC on        G
both input goods and input services is accumulated in the
electronic ledger and is then utilised for the payment of output
tax. In making such an assumption, the formula tilts the balance
in favour of the Revenue by reducing the refund granted. We are
equally cognizant of the fact that the proposed solution, that is        H
176           SUPREME COURT REPORTS                     [2021] 15 S.C.R.


A     prescribing an order of utilisation of the ITC accumulated on input
      services and input goods, may tilt the balance entirely in favour
      of the assessee as that would make a contrary assumption that
      the output tax is discharged by the ITC accumulated on account
      of input services entirely. Another possible solution could be that
      the Rule itself provides for a statutory assumption or a deeming
B
      fiction of utilisation of a certain percentage of ITC on input
      services towards the payment of output tax for the purpose of
      calculation of refund. [Para 105][273-A-E]
            8. The above judicial precedents indicate that in the field
      of taxation, this Court has only intervened to read down or
C     interpret a formula if the formula leads to absurd results or is
      unworkable. In the present case however, the formula is not
      ambiguous in nature or unworkable, nor is it opposed to the intent
      of the legislature in granting limited refund on accumulation of
      unutilised ITC. It is merely the case that the practical effect of
D     the formula might result in certain inequities. The reading down
      of the formula as proposed by prescribing an order of utilisation
      would take this Court down the path of recrafting the formula
      and walk into the shoes of the executive or the legislature, which
      is impermissible. Accordingly, we shall refrain from replacing the
      wisdom of the legislature or its delegate with our own in such a
E     case. However, given the anomalies pointed out by the assessees,
      we strongly urge the GST Council to reconsider the formula and
      take a policy decision regarding the same. [Para 111][280-D-F]

              A Introduction
E
             1. Parliament while enacting the Central Goods and Services Tax
      Act 2017,1 has incorporated a provision for refund of tax in Section 54.
      Sub-Section (3) embodies a provision for refund of unutilised input tax
      credit2 in cases involving:
F             (i) zero rated supplies made without payment of tax; and
              (ii) credit accumulation “on account of rate of tax on inputs being
                   higher than rate of tax on output supplies”.
             2. While envisaging a refund in the latter of the above two
      situations, Parliament was cognizant of the fact that ITC may accumulate
G     due to a variety of reasons. However, Parliament envisaged a specific
      situation where the credit has accumulated due to an inverted duty
      structure, that is where the accumulation of ITC is because the rate of
      tax on inputs is higher than the rate of tax on output supplies. Taking

          “ITC”
       UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                             181
           [DR DHANANJAYA Y CHANDRACHUD, J.]

legislative note of this situation, a provision for refund has been provided      A
for in Section 54(3). The Central Goods and Service Tax Rules 2017 3
have been formulated in pursuance of the rule making power conferred
by Section 164 of the CGST Act. Rule 89(5) provides a formula for the
refund of ITC, in “a case of refund on account of inverted duty structure”.
The said formula uses the term “Net ITC”. In defining the expression
                                                                                  B
“Net ITC”, Rule 89(5) speaks of “input tax credit availed on inputs”.
          B Factual Backdrop
       3. Writ petitions under Article 226 of the Constitution were
instituted before the High Court of Gujarat and the High Court of
Judicature at Madras. The petitioners before the High Court submitted             C
inter alia that
          (i) Section 54(3) allows for a refund of ITC where the
              accumulation is due to an inverted duty structure;
          (iii) ITC includes the credit of input tax charged on the supply of
                goods as well as services;                                        D
          (iv) Section 54(3) does not restrict the entitlement of refund only
               to unutilised ITC which is accumulated due to the rate of tax
               on inputs being higher than the rate of tax on output supplies.
               It also allows for refund of unutilised ITC when the rate of
               tax on input services is higher than the rate of tax on output     E
               supplies;
          (v) While Section 54(3) allows for a refund of ITC originating in
              inputs as well as input services, Rule 89(5) is ultra vires in so
              far as it excludes tax on input services from the purview of
              the formula; and                                                    F
          (vi) In the event that Section 54(3) is interpreted as a restriction
               against a claim for refund of accumulated ITC by confining it
               only to tax on inputs, it would be unconstitutional as it would
               lead to discrimination between inputs and input services.
      4. By its judgment dated 24 July 2020 in VKC Footsteps India                G
Pvt. Ltd. v. Union of India4, the Division Bench of the Gujarat High
Court, held that:

A               “Explanation (a) to Rule 89(5) which denies the refund of
                “unutilised input tax” paid on “input services” as part of “input tax
                credit” accumulated on account of inverted duty structure is ultra
                vires the provision of Section 54(3) of the CGST Act, 2017.”
              The High Court therefore directed the Union Government to allow
B     the claim for refund made by the petitioners before it, considering unutilised
      ITC on input services as part of “Net ITC” for the purpose of calculating
      refund in terms of Rule 89(5), in furtherance of Section 54(3).
             5. By its judgment dated 21 September 2020, in Tvl.
      Transtonnelstroy Afcons Joint Venture v. Union of India 5 and
C     connected cases the Division Bench of the Madras High Court came to
      a contrary conclusion, after having noticed the view of the Gujarat High
      Court, which it has declined to follow. The Madras High Court has
      concluded that
                “63…
D               (1) Section 54(3)(ii) does not infringe Article 14.
                (2) Refund is a statutory right and the extension of the benefit of
                refund only to the unutilised credit that accumulates on account of
                the rate of tax on input goods being higher than the rate of tax on
                output supplies by excluding unutilised input tax credit that
E               accumulated on account of input services is a valid classification
                and a valid exercise of legislative power.”
             6. The writ petitions challenging the validity of Rule 89(5) on the
      ground that it is ultra vires Section 54(3)(ii) were dismissed. The
      divergence between the views of the Gujarat High Court on the one
      hand, and the Madras High Court on the other, forms the subject matter
F
      of this batch of appeals.
                C Statutory Provisions
             7. Section 54 of the CGST Act provides for a refund of ax. Under
      sub-Section (1) of Section 54, a person claiming a refund of “tax and
G     interest, if any, paid on such tax or any other amount paid” has to make

      The amendment was with prospective effect. Rule 89(5), as it
stands at present, was substituted on 13 June 2018 by the Central Goods
and Services Tax (Fifth Amendment) Rules 20188. By the amendment,

             10. Before we proceed to analyse the submissions and formulate
      the points for consideration, it is necessary to emphasise at the outset
      that one of the core issues in the present batch of cases would turn upon
B     the interpretation of the expression “inputs” in Section 54(3)(ii) of CGST
      Act and the definition of “Net ITC” in the amended Rule 89(5). During
      the course of the submissions, in the interest of maintaining clarity, Counsel
      on both sides used the expression ‘input goods’ while dealing with goods
      that are used as inputs and ‘input services’ while dealing with services
      that are used as inputs. We propose to use the same formulation to
C     ensure conceptual clarity while distinguishing between goods which are
      used as inputs and services which are used as inputs. With this preface,
      we shall now proceed to deal with the submissions of the parties.

              D.1.1 Part I- Distinction between goods and services
            11. Mr N Venkataraman, learned Additional Solicitor General 9 led
      the arguments on behalf of the Union Government in assailing the
      correctness of the decision of the Gujarat High Court (and supporting
E     the decision of Madras High Court). Mr Venkataraman urged that:
              (i)    Goods and services are distinct at a constitutional level. Article
                     366(12) of the Constitution defines goods, while Section
                     366(26A) defines services. Under the CGST Act, the
                     expression ‘input’ in Section 2(59) means tangible
F                    commodities other than capital goods, while on the other hand
                     ‘input service’ in Section 2(60) means any service used or
                     intended to be used by a supplier for business. Hence, ‘goods’
                     and ‘services’ and ‘inputs’ and ‘input services’ have distinct
                     definitions;
G             (ii) Article 366(12A) defines ‘goods and services tax’ to mean
                   any tax on the supply of goods or services or both except
                   taxes on the supply of alcoholic liquor for human consumption;

         (iii) Article 246A, which traces the source of power of taxation         A
               and identifies the fields of taxation, empowers the Parliament,
               the States and Union Territories to impose simultaneous tax
               both on goods and services. Consequently, though goods and
               services are brought to tax under a common code, both the
               Constitution and the statute have maintained a distinction
                                                                                  B
               between goods and services. They remain distinct for
               prescription, treatment and interpretation;
         (iv) Section 2(62) and Section 2(63) define ‘input tax’ and ‘input
              tax credit’ which include taxes paid on goods (input goods)
              and services (input services) either under CGST, State Goods
              and Services Tax Act10 and Integrated Goods and Services            C
              Tax Act 201711;
         (v) Input tax means a tax charged both on goods and services.
             These are taxes paid by a supplier on their outward supplies
             as defined under Section 2(83) which become inward supply
             for the recipient under Section 2(67); and                           D

         (vi) The need to integrate both taxes on input goods and input
              services is to enable credit on a single pool for further cross
              utilisation on both goods and services.
         D.1.2 Part II- Interpretation of Section 54(3)                           E
         (i) The structure of Section 54(3) is as follows:
         (a) The opening clause permits a registered person to claim refund
             of any unutilised ITC at the end of any tax period.
         (b) The main clause permits:
                                                                                  F
            i. a claim;
            ii. in the nature of refund;
            iii. of any unutilized ITC; and
            iv. at the end of the tax period.                                     G
         (ii) Section 54(3) contains three provisos, out of which the first
              proviso falls for interpretation in this case. The three provisos
              share common features which indicate that these provisos

188      SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A         are in the nature of restrictions and not conditions (or
          qualifications);
      (iii) The provisos to Section 54(3) should be construed as
            restrictions for the following reasons:
         (a) The expression employed in the main clause of Section
B            54(3) is ‘claim’ whereas the provisos restrict this ambit
             by the use of the expression ‘allowed’. The expression
             ‘allowed’ appears in all the three provisos;
         (b) The main clause of Section 54(3) uses the expression “any
             unutilised ITC”. On the other hand, the expression ‘any’
C            is conspicuous by its absence in all the provisos;
         (c) The main clause of Section 54(3) uses the expression “a
             registered person may claim refund” while on the other
             hand, the three provisos have employed a restrictive
             expression or a negative expression, that is, “no refund of
D            unutilized ITC shall be allowed”;
         (d) When the main clause used the expression ‘any’, this is
             expressly restricted by the use of the expression “no refund
             of unutilised ITC shall be allowed in cases other than”. In
             other words, the expression ‘any’ has been restricted to
E            “other than”; and
         (e) In view of the above, the provisos under Section 54(3)
             have to be read and interpreted as restrictions and not as
             qualifications;
      (iv) The first proviso restricts the refund of unutilized ITC only to
F
           two situations and the subsequent two provisos further restrict
           it to one of the categories out of the two in the first proviso.
           The two situations contemplated in the first proviso deal with
           contrasting situations with stark differences:
         (a) Sub clause (i) of the first proviso deals with zero rated
G            supplies which are exports. Exports of goods and services
             are not taxable. Hence, the taxes paid either on exported
             goods or services or on the input goods/input services or
             both used in the export of such goods and services need
             to be totally refunded;

    (b) However, sub-clause (ii) of the first proviso deals with          A
        domestic supplies which are taxable outward supplies, in
        respect of which Parliament has chosen to allow refund
        of unutilised ITC only to the extent of the ‘credit
        accumulated on account of rate of tax on inputs’;
 (v) The first proviso cannot be read as a mere qualification or          B
     eligibility for the grant of refund on the entire unutilised ITC
     comprising input goods and input services by a specified
     registered person, for the following reasons:
    (a) The expression used is ‘the credit’ and the accumulation
        is restricted only on account of ‘inputs’. This cannot be         C
        read or interpreted to include input services and capital
        goods;
    (b) The proviso limits the grant of refund only to two
        circumstances and hence the limitation has to be read as
        it is without extending it to input services and capital goods,
                                                                          D
        specifically since the legislature has not included them;
    (c) If the intention was to allow refund of unutilised ITC on
        account of input services and capital goods, in addition to
        input goods, such an intent would have been conveyed
        through statutory language, which is missing;
                                                                          E
    (d) The expression ‘credit’ has to be read along with ‘inputs’
        and cannot be read as to extend a refund to input services
        and capital goods also, which are expressly not referred
        to in the proviso;
    (e) ‘The credit’ in sub clause (ii) can go only with the
                                                                          F
        expression ‘inputs’ and excludes accumulation of any
        credit on account of rate of tax on input services or capital
        goods;
    (f) When there is an express inclusion limited only to the credit
        accumulation arising out of ‘inputs’, it would not be
        permissible to include input services and capital goods in        G
        the face of the statutory provision. What has not been
        included in the statute should not be included by way of
        judicial interpretation;
 (xvi) The reason why Parliament has adopted the expression
       ‘unutilised ITC’ in the main part of Section 54(3) and the         H
190   SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A       first proviso, but has chosen to employ only the expression
        ‘inputs’ is as follows:
      (a) There is a significant difference between the main
          provision and the first proviso even in the use of the
          expression ‘unutilized ITC’. The expression ‘any’ in the
B         main Section is absent in the first proviso with the further
          limitation that refund of ‘unutilized ITC’ is limited only to
          two circumstances specified in the proviso;
      (b) The first situation deals with refund on account of zero-
          rated supplies which are exports where refund is granted
C         on all the taxes paid on input goods, input services including
          taxes paid on export supplies. This is evident from
          Explanation-I to Section 54(3) where the expression refund
          permits the above;
      (c) However, when it comes to an inverted duty tax structure,
D         the refund is limited to only one category namely, ‘credit
          accumulated on account of rate of tax on inputs’;
      (d) The expression ‘unutilized ITC’ could comprise of taxes
          paid both on input goods and input services, and the first
          proviso and the main Section necessarily have to employ
E         the expression ‘unutilized ITC’ to take care of zero-rated
          supplies which are exports under the first category;
      (e) When it comes to an inverted tax structure, it is limited
          only to ‘inputs’. It is a common fact that unutilized credit
          arising out of input services also partakes the character
F         of unutilized ITC;
      (f) Parliament has rightly used the expression ‘unutilised ITC’
          both in the main clause and in the first proviso to deal
          with zero rated supplies and restricted refund to those
          arising out of ‘inputs’ when it comes to an inverted
          structure;
G
      (g) Parliament could not have used the expression ‘inputs’ in
          the main clause and first proviso as this would act as a
          disability to zero rated supplies where Parliament intended
          to grant a refund arising out of both input goods and input
          services;

    [DR DHANANJAYA Y CHANDRACHUD, J.]

        (h) Parliament has therefore appropriately employed the              A
            expression ‘unutilized ITC’ in the main clause and the
            first proviso and has used the limited expression ‘inputs’
            in sub-clause (ii) to the first proviso in the inverted
            structure;
 (vii) Explanation-I to Section 54(3) defines refund in three parts:         B
        (a) When it comes to zero rated supplies on exports, it extends
            the refund to ‘inputs’, ‘input services’ and also taxes paid
            on zero rated supplies of goods or services or both;
        (b) When it comes to deemed exports, it restricts the refund
            of tax only on the supply of goods;                              C

        (c) When it comes to inverted structure, it limits it as provided
            in the proviso to Section 54(3). This is one more reason to
            read the proviso to Section 54(3), as a restriction and not
            as a qualification. If the intent of Parliament was to grant
            a refund arising both out of input goods and input services      D
            even in the case of inverted tax structure, it would have
            defined refund in Explanation-I at par with zero rated
            supplies and there was no need to limit it only to one
            situation of the credit accumulation arising on account of
            ‘inputs’.                                                        E
 D.1.3. Part III- Legal Propositions
 (i)       Article 265 of the Constitution provides that no tax shall be
           levied or collected except by authority of law. There being
           no challenge either to the levy or collection of taxes in these
           cases, taxes paid into the coffers of the Union Government        F
           or the States become the property of the Union/States;
 (ii)      The refund of taxes is neither a fundamental right nor a
           constitutional right. The Constitution only guarantees that
           the levy should be legal and that the collection should be in
           accordance with law. There is no constitutional right to          G
           refund. Refund is always a matter of a statutory prescription
           and can be regulated by the statute subject to conditions
           and limitations;
 (iii)     Even in the case of an illegal levy or a levy which is
           unconstitutional, the decision of the nine judges Bench in        H

A                       Mafatlal Industries Limited v. Union of India12 held
                        that the right of refund is not automatic. The burden of
                        proof lies on the claimant to establish that it would not cause
                        unjust enrichment;
               (iv)     Though tax enactments are subject to Articles 14 and
B                       19(1)(g) of the Constitution, this is subject to two well-settled
                        principles:
                     (a) Discriminatory treatment under tax laws is not per se
                         invalid. It is invalid only when equals are treated unequally
                         or unequals are treated equally. Both under the
C                        Constitution and the CGST Act, goods, services, input
                         (goods) and input services are not one and the same.
                         These are distinct species, though covered by a common
                         code; and
                     (b) The legislature is entitled to the widest latitude when it
D                        identifies categories of classification and unless things
                         constituting the same class are treated differently without
                         a rationale, the provision cannot be declared as
                         unconstitutional;
               (v)      The doctrine of reading down is employed to narrow down
E                       the scope of a proviso under challenge, when it may
                        otherwise be unconstitutional. The doctrine cannot result in
                        expansion of a statutory provision for refund which would
                        amount to rewriting the legislation;
               (vi)     Accepting the submission of the assessees that goods and
F                       services must be treated at par can lead to drastic
                        consequences in terms of:
                          (a) rates of taxes;
                          (b) concessions, benefits and exemptions;
                          (c) intervention in the areas of political, economic and
G                         legislative policies;
               (vii)    Refund of taxes is one form of granting exemption;

          (viii) Once a refund is construed as a form of exemption from            A
                 taxes, the provision has to attract strict interpretation;
          (ix)    Exemptions, concessions and exceptions have to be treated
                  at par and must be strictly construed;
          (x)     ITC is not a matter of right and the burden of proof is on
                  the assessee to establish a claim for a concession or benefit;   B

          (xi)    The manner in which a proviso can be construed has been
                  elucidated in the precedents of this Court. A proviso may
                  not be only an exception but may constitute a restriction on
                  the operation of the main statutory provision; and
                                                                                   C

       13. Mr V Sridharan, learned Senior Counsel appearing on behalf
of the assessee13 submitted:
          (i)     The assessee is, inter alia, engaged in the manufacture
                  and supply of footwear which attracts output tax (goods
                  and services tax14) at the rate of 5%;                           E

          (ii)    The assessee, inter alia, procures input goods such as
                  synthetic leather, PU Polyol and input services such as job
                  work service, goods transport agency service on payment
                  of applicable GST for use in the course of business and
                  avails ITC on the GST paid thereon. A majority of the input      F
                  goods and input services attract tax at the rate of 12% or
                  18%;
          (iii)   The rate of GST paid by the assessee on procurement of
                  input goods and input services is higher than the rate of tax
                  payable on their outward supply of footwear. Therefore,          G
                  despite utilization of credit for payment of GST on outward
                  supply, there is an accumulation of unutilized ITC in the

A           (iv)    The assessee applied for refund of such unutilised
                    accumulated ITC under Section 54(3) of the CGST Act
                    read with Rule 89(5) of the CGST Rules;
            (v)     Rule 89(5) of the CGST Rules as originally enacted provided
                    for refund of ITC availed on both inputs (that is input goods)
B                   and input services and was in line with Section 54(3) of the
                    CGST Act. Accordingly, the assessee was granted refund
                    of such unutilised ITC;
            (vi)    Rule 89(5) was substituted by Notification No. 21/2018-
                    CT dated 18 April 2018 prescribing a revised formula for
C                   determining the refund on account of inverted duty structure.
                    The above substitution was given retrospective effect from
                    1 July 2017 by Notification No. 26/2018-CT dated 13 June
                    2018;
            (vii)   The revised formula inter alia excludes ‘input services’
D                   from the scope of ‘Net ITC’ for computation of the refund
                    amount under the said Rule;
            (viii) The substituted Rule 89(5) of the CGST Rules denies refund
                   on the unutilised ITC availed on input services and allows
                   relief of refund of ITC availed on input goods alone;
E           (ix)    The Revenue is relying on amended Rule 89(5) to contend
                    that refund will not be allowed on taxes paid on input
                    services; and
            (x)     The Revenue is allowing refund of accumulated ITC of tax
                    paid on input goods such as synthetic leather, and PU Polyol.
F                   Further, the Revenue is allowing accumulation of ITC paid
                    on procurement of input services such as job work service
                    and goods transport agency service. However, the refund
                    of accumulated unutilised ITC paid on input services is being
                    denied and refund already granted has been recovered from
                    the assessee.
G
            14. Mr Sridharan urged that Rule 89(5) of the CGST Rules, to the
      extent to which it denies refund of ITC relatable to input services, is
      ultra vires Section 54. The submission has been premised on the
      following propositions:

           [DR DHANANJAYA Y CHANDRACHUD, J.]

          (i)    GST is a destination-based consumption tax. The fundamental           A
                 principle of GST laws worldwide is that it is a multistage tax.
                 Each point in a supply chain is potentially taxed. However,
                 suppliers are entitled to avail credit of taxes paid at an anterior
                 stage. This feature of GST leads to its description as being a
                 tax on value addition, with the final consumer alone ultimately
                                                                                       B
                 bearing the tax. The GST laws enacted in India are also
                 based on this principle;
          (ii) In All India Federation of Tax Practitioners v. Union of
               India15, this Court held that excise duty, service tax and value
               added tax legislation provide for taxes on value addition and
               are destination based-consumption taxes. These are not                  C
               charges on the business but on the consumer. Though the
               erstwhile tax legislation, prior to the enforcement of the
               Constitution (One Hundred and First Amendment) Act 2016,
               was based on the principle of value addition and consumption
               tax, there was no seamless flow of credit between Central               D
               and State levies. This anomaly was sought to be addressed
               by the constitutional amendment and by the legislation which
               has been enacted in pursuance of it;
          (iii) The purpose of the One Hundred and First Constitutional
                Amendment was:                                                         E
                (a) to replace a number of indirect taxes being levied by the
                    Union Government and the State Governments;
                (b) to obviate and remove the cascading effect of taxes; and
                (c) to provide for a common national market for goods and              F
                    services.
          (iv) The Statement of Objects and Reasons accompanying the
               bill introducing the CGST Act also emphasised that there
               would be a seamless transfer of ITC from one stage to another
               in the chain of value addition;
                                                                                       G

              Organisation of Economic Co-operation and Development
              which emphasise that

A        (a) value added tax systems are designed to tax final
             consumption;
         (b) only the consumers should bear the tax burden; and
         (c) the main characteristic of a value added tax is of preserving
             neutrality in the value chain.
B
      (vi) Compelling economic and fiscal realities necessitated the levy
           of value added tax like GST in place of traditional excise
           duties, service tax, sales tax and other legislation;
      (vii) In a tax regime which was not based on value added tax,
C           ensuring refund of tax paid at various stages of manufacturing
            would be cumbersome and complicated. It was to obviate
            the problems of the earlier regime that GST legislation was
            enacted by various countries including India to fully effectuate
            the principle underlying value-added destination-based
            consumption tax;
D
      (viii) The situation in which the quantum of input taxes exceeds
             output tax is an anomaly, aberration and distortion resulting
             from various sources of taxes and conflicts with the
             fundamental principles of GST. The impact of these
             distortions can be revealed by practical examples involving
E            situations such as
         (a) Intermediate products attracting a lower rate of tax; and
         (b) Intermediate products attracting a higher rate of tax.
      (ix) As a result, varied situations of economic distortion resulting
F          from a cascading effect of taxes in the form of unabsorbed
           ITC emerged due to variations in the rate of taxes. This is
           against the basic tenets of GST. GST being a consumption
           tax, postulates that the only tax in the entire chain should be
           the tax charged to the end customer without any ‘sticking’
           or unabsorbed ITC;
G
      (x) Government may in the public interest impose lower rates of
          tax on products such as fertilizers, tractors and lower-price
          footwear. The objective of taxing such goods at a lower rate
          is frustrated if inputs for making the final products are taxed
          at a higher rate and no refund of unutilized credit is granted.

      Refund of unutilised7 ITC seeks to achieve the objective of         A
      value-added consumption-based taxation in its true sense;
 (xi) Cognizant of the anomaly resulting from inverted duty
      structures, the erstwhile State Value Added Tax legislations
      provided for refund of unutilized ITC, even before the GST
      legislation saw the light of the day;                               B
 (xii) A near perfect GST legislation provides for refund of ITC in
       a situation involving an inverted duty structure. The provisions
       for refund ensure that anomalies in tax rates do not result in
       distortions to the fundamental features of GST which remains
       a true consumption tax. ITC may accumulate for a variety           C
       of reasons including (a) inverted duty structure, that is, GST
       on output supplies is less than the GST on the input supplies;
       (b) stock accumulation; (c) capital goods; and (d) partial
       reverse charge mechanism for certain services;
 (xiii) The cascading effect or sticking credit may arise on account      D
        of higher taxes paid on input goods or input services. Refund
        of unutilized ITC will ensure the elimination of the cascading
        effect of taxes in a true sense;
 (xiv) Section 54(3) has been enacted to achieve the objective of
       removing the cascading effect of unutilized ITC. Section           E
       54(3) provides for refund of “any unutilised input tax credit”
       but the refund is available in only two situations namely, (a)
       zero rated supplies; and (b) inverted duty structure. The
       quantum of refund is provided by the main part of Section
       54(3) which stipulates the refund of any unutilised ITC. This
       includes credit availed on input goods as well as on input         F
       services having regard to the definitions contained in Sections
       2(62) and 2(63);
 (xv) The proviso only provides for cases in which the refund under
      the main provisions of Section 54(3) will be available. Once
      the requirement of inverted duty structure in proviso (ii) is       G
      fulfilled, the entire unutilised ITC has to be refunded. The
      reason why proviso (ii) defines the inverted duty structure
      with reference to only input (goods) vis-a-vis output supplies
      may be that while services (barring a few) were leviable to
      tax at 18 per cent, goods were subject to various categories
                                                                          H
198                  SUPREME COURT REPORTS                        [2021] 15 S.C.R.


A                     of rates. If input services were also considered for
                      determining inverted duty structure, refund may be required
                      to be granted practically to all the assessees. Hence, the
                      legislature defined inverted duty structure only with reference
                      to ‘inputs’ (input goods). However, once a case fulfils the
                      condition of an inverted duty structure, refund of the entire
B
                      unutilised ITC which is attributable to inverted duty structure
                      supplies is allowed, including the credit availed on input goods
                      and input services;
               (xvi) A circular has been issued on 31 December 2018, being
                     Circular No. 79/53/2018-GST by the Central Board of
C                    Indirect Taxes and Customs16. In a situation where GST on
                     some inputs is higher than the rate of GST applicable on the
                     output supply, while the rate of GST on other inputs is lower
                     than the GST on the output supply, the circular provides that
                     refund will be granted by taking the ITC availed on all inputs,
D                    including input services, which attract a lower rate of tax
                     than on output supply. The circular, in other words, does not
                     treat Section 54(3) read with the proviso (ii) as qualifying
                     the extent of refund but only as a pre-condition to qualify for
                     the grant of refund;
E              (xvii)Proviso (ii) to Section 54(3) only lays down ‘cases’ where
                     refund is eligible but it does not define the quantum of refund.
                     This will be evident from the following:
               (a)     The quantum of refund is provided in the main segment to
                       Section 54(3). The expression “any” unutilised ITC means
F                      all unutilised ITC;
               (b)     The definitions of ‘input tax credit’ under Section 2(63) and
                       ‘input tax’ in Section 2(62) would indicate that both input
                       goods and input services are included;
               (c)     The proviso indicates the ‘cases’ in which refund will be
G                      eligible. The expression ‘cases’ means situations or
                       circumstances;
               (d)     Clause (ii) of the first proviso commences with the
                       expression “where” which signifies that what follows will
                       be a situation or aspect of something;

 (e)   The statutory provision must be read as a whole and in the        A
       context of other provisions. All the three provisos refer to
       cases in which refund is allowed or, as the case may be,
       not allowed and do not refer to the quantum of refund;
 (f)   Clause (ii) of the proviso refers to “the credit”. The use of
       the definitive article clearly indicates that the reference is    B
       to unutilised ITC already mentioned in the main part of
       Section 54(3). The expression ‘the’ signifies one particular
       sum or credit and any attempt to bifurcate it into credit on
       input goods and input services will produce anomalous
       results;
                                                                         C
 (g)   The expression ‘accumulated’ signifies the credit balance
       which is unutilized after credit has been availed and utilised
       for making payments on output tax on outward supplies;
 (h)   Clause (ii) of the proviso uses the words “on account of”
       which means by reason of or because of. By stipulating            D
       that the proviso provides for the quantum of refunds, the
       Revenue is attempting to substitute the words “on account
       of” with “to the extent of”;
 (i)   The submission of the Revenue cannot be accepted because
       clause (ii) of the proviso refers to the rate of tax. To accept   E
       the interpretation of the Revenue, the words “and only to
       the extent” will have to be added to the proviso;
 (j)   Though the CGST Act makes a distinction between ‘inputs’
       and ‘input services’, this is only relevant at the stage prior
       to the availment of credit, namely to determine the eligibility   F
       of credits under Sections 16 and 17 of the CGST Act. After
       the credit has been availed, it goes in a common pool from
       which the credit is utilised for making payment for output
       tax. Utilization happens from the entire credit available for
       the tax period in this common pool and it cannot be co-
       related to ITC availed on particular input goods or input         G
       services. The balance is the unutilised ITC at the end of
       the tax period. At this stage, it is not possible to determine
       whether the balance pertains to ITC availed on input goods
       or on input services; and
                                                                         H

A     (k)     Alternatively, the words, “rate of tax on inputs” must be
              read to include whatever goes in the making of output
              supplies namely, both input goods and input services.
      (xviii) Explanation (1) to Section 54 covers four cases of refund:
              (a) refund of tax paid on zero-rated supplies of goods or
B             services; (b) refund of tax paid on input goods or input
              services used in making zero rated supplies (where no output
              tax is paid); (c) refund of tax on the supply of goods regarded
              as deemed exports; (d) refund of unutilised ITC under sub-
              Section (3). In the case of (a) above, the legislature has
              used the expression “goods or services”; in the case of
C             (b), “inputs or input services”; in the case of (c), “goods or
              services”. However, in respect of refund of unutilised ITC,
              it has only been provided that the refund will be granted as
              provided under sub-Section (3). The explanation does not
              restrict the refund only to credit availed on input goods in
D             the case of an inverted rated structure;
      (xix) Rule 89(5) by confining refund of unutilised ITC on input
            goods and denying refund of ITC on input services curtails
            the ambit of Section 54(3) and is hence ultra vires:
      (a)     Rule 89(5) originally provided for refund of ITC paid both
E             on input goods and input services but it was amended with
              retrospective effect to restrict refund only to ITC availed
              on input goods;
      (b)     After the amendment in terms of the formula, the ratio of
              proportionate turnover is applied only to ITC availed on
F             input goods. However, after arriving at the proportionate
              value, the entire amount of tax paid on output supplies is
              deducted. The formula erroneously assumes that the entire
              output tax will be paid from ITC availed on input goods
              and the credit on input services will not be utilised for
G             payment of output tax. If the rule took into computation
              ITC availed on both input goods and input services, both
              parts of the formula would be comparable and would result
              in a correct amount of unutilised ITC attributable to an
              inverted duty structure. The rule is ultra vires Section 54(3)
              since it restricts the computation of refund only by taking

    [DR DHANANJAYA Y CHANDRACHUD, J.]

        into account the credit availed on input goods. Section 54(3)   A
        provides for entitlement to refund, its quantum and the
        cases in which the refund is to be granted. Section 54(3)
        being a code in itself, there is no reference to a provision
        enabling the Government to frame rules in this regard.
        Hence, with reference to Section 54(3), any exercise of
                                                                        B
        the rule making power is unwarranted;
 (xx)   The general rule making power conferred by Section 164(1)
        is to carry out the provisions of the CGST Act and cannot
        save the offending provisions of the Explanation to Rule
        89(5):
                                                                        C
 (a)    Accumulation of credit may occur due to various reasons
        such as absence of outward supplies in a tax period, supplies
        made at a loss, bulk purchase of inputs, excess opening
        balance of credit, and change in the rate of tax during the
        tax period;
                                                                        D
 (b)    A rule which provides for the identification of unutilised
        ITC which is attributable to supplies having an inverted duty
        structure and bifurcating it from credit accumulating due to
        other causes would be for the purpose of carrying out the
        provisions of the CGST Act;
                                                                        E
 (c)    A rule may provide a proportionate formula for determining
        the pro-rata amount of credit relatable to the inverted duty
        structure vis-a-vis total turnover. Such a formula may be
        needed where the assessee is making supplies involving an
        inverted duty structure as well as supplies not involving it;
                                                                        F
 (d)    Where the entire supplies made by assessee are by way of
        export, the entire ITC is refundable under proviso (i).
        However, where an assessee is engaged in exporting goods
        and in domestic supplies, the assessee should be eligible for
        claiming refund from ITC attributable to exports while not
        being entitled to cash refund on ITC relatable to domestic      G
        supplies. In such cases where an assessee makes both
        domestic supplies as well as exports, a formula may be
        required to estimate the ITC relatable to exports which alone
        can be refunded to the assessee in a similar manner if an
        assessee has output supplies. Where an assessee has output
                                                                        H
202                  SUPREME COURT REPORTS                        [2021] 15 S.C.R.


A                      supplies having an inverted duty structure and output supplies
                       not having an inverted duty structure, refund is to be given
                       only for the former and not for the latter. The formula would
                       be required for that purpose. Rule 89(4) relating to export
                       adopts pro-rata of export turnover to total turnover as the
                       basis. Rule 89(5) is similarly enacted to deal with an assessee
B
                       having inverted duty structure supplies and other supplies
                       not having an inverted duty structure. This should be the
                       sole purpose of the formula for Rule 89(5);
               (e)     However, Rule 89(5) in the garb of fixing a formula for
                       determining pro-rata the amount of credit relatable to the
C                      inverted duty structure vis-à-vis total turnover has restricted
                       the refund to ITC on input goods by denying it on input
                       services. This has been done by defining ‘Net ITC’ to mean
                       ITC availed on all ‘inputs’, thus overlooking ITC relatable
                       to input services. Such a rule cannot be treated as one for
D                      carrying out the purpose of the CGST Act;
               (xxi) A delegated legislation can be struck down as ultra vires
                     of a principal statute. The laying of delegated legislation
                     before Parliament does not confer any validity on such
                     ultra vires rules. The process of laying rules before
E                    Parliament and making them subject to modification or
                     annulment cannot be equated with legislation which has
                     the assent of the President, or the Governor, as the case
                     may be. The doctrine of ultra vires will apply even if a
                     resolution is passed by Parliament approving or modifying
                     the rules. Though, the CGST Rules have been laid before
F                    Parliament, any part which is ultra vires the CGST Act is
                     liable to be struck down;
               (xxii) The fact that the rules have been recommended by the
                      Goods and Services Tax Council17 does not elevate them
                      to the status of a statute enacted by the legislature. The
G                     recommendations made by the GST Council under Article
                      279A(4) of the Constitution take effect only after they have
                      been incorporated in the legislation passed by the Parliament
                      or the State legislature. The CGST Act and SGST Act
                      have been enacted on the recommendations of the GST

                  Council, in exercise of the power under Article 279A, while      A
                  the CGST Rules have been framed on the recommendations
                  of the GST Council in exercise of the powers conferred
                  by Section 2(87) and Section 164 of the CGST Act. There
                  is a clear distinction between laws enacted by the legislature
                  and delegated legislation. A rule made on the
                                                                                   B
                  recommendation of the GST Council must be in consonance
                  with the relevant legislation, failing which it would be ultra
                  vires;
          (xxiii) Section 54(3) grants a refund of the entire unutilised ITC
                  in the case of an inverted duty structure irrespective of
                  whether the credit pertains to input goods or input services.    C
                  The amendment made in Rule 89(5) which restricts the
                  refund of unutilised ITC availed only on ‘inputs’ is ultra
                  vires Section 54(3); and
          (xxiv) By virtue of the doctrine of severability that portion of Rule
                 89(5) which is ultra vires may be struck down. This would         D
                 not constitute judicial legislation. The challenge to the vires
                 of Rule 89(5) is only because of the definition of ‘Net ITC’
                 in the explanation to the rule. The explanation defines net
                 ITC to mean ITC availed on inputs during relevant period.
                 Section 54(3) allows refund of any unutilized ITC and not         E
                 only credit on input goods. Consequently, only if the
                 expression “on inputs” employed in Explanation (a) to Rule
                 89(5) is struck down, will Rule 89(5) be in line with Section
                 54(3).
          15. Mr Sujit Ghosh, learned Counsel18 submitted that                     F
          (i)   The meaning of the expression “unutilised ITC” is credit on
                goods as well as services (which remains after paying output
                tax) in view of the definitions contained in Section 2(63) read
                with Section 2(62) of the CGST Act;
          (ii) In Explanation-I to Section 54, the expression ‘refund’ qua         G
               zero rated supplies
          (a) is an inclusive definition which refers to unutilized ITC qua
              Section 54 (3);

A     (b) covers a refund on both input goods and input services for
          the purpose of Section 54(3);
      (c) in relation to zero rated supplies, the expression refund in
          Explanation-I to Section 54 is clarificatory though it uses the
          words “inputs” and “input services”;
B     (d) The right to refund in the case of zero-rated supplies arises
          in Section 16(3)(a);
      (e) The provision uses the phrase “refund of unutilised ITC in
          accordance with Section 54”; and

C     (f) The meaning of the term ‘refund’ for both export and domestic
          supplies is one and the same.
      (iii) The construction of Section 54(3) must be based on the
            following circumstances:
      (a) The substantive part deals with the quantum of refund. The
D         proviso is not a restriction but merely prescribes threshold
          conditions;
      (b) Threshold conditions are evident from the use of the
          expression “in cases”;
      (c) Each of the three provisos lays down (i) situations; and (ii)
E         conditions, as evident from the following table:

    [DR DHANANJAYA Y CHANDRACHUD, J.]

 (iv)   The object and purpose of Section 54(3) must be borne in         A
        mind:
 (a)    The purpose of the provision is to give effect to the doctrine
        of equivalence or neutrality which is the basic objective of
        the GST and this is sought to be achieved by granting
        seamless credit through Section 16;                              B
 (b)    The legislative background and preparatory material duly
        support the purpose of the legislation;
 (c)    The State does not want the taxpayers to suffer the ill effect
        of tax cascading solely because of its decision to offer a
        reduced rate of tax on outputs, relative to the tax rate on      C
        inputs;
 (d)    In the case of the petitioner which is engaged in providing
        services to Chennai Metro Rail, the original rate of output
        tax used to be 18 per cent while the input tax on goods and
        services was between 18 per cent to 28 per cent. As a            D
        result of Notification No. 1/2018 and a corresponding State
        notification, the rate of tax on output supplies, namely
        construction of mono rails and metro rails, was reduced to
        12 per cent;
 (e)    Section 54(3) is not intended to cover a situation where the     E
        inverted duty structure is created by assessee due to its
        own actions such as discount/distress/non-supply as
        distinguished from the rate structure created by the State;
 (f)    The object of achieving tax neutrality is sought to be
        implemented for the first time through the anti-profiteering     F
        measure embodied in Section 171;
 (v)    The international jurisprudence on GST and tax neutrality
        postulates that such taxes are not a permanent cost to the
        business and that businesses are pass through entities. The
        essential character is of an economically neutral tax through    G
        a seamless flow of credit;
 (vi)   A contextual interpretation of Section 54(3) must look at
        the overall scheme of the statute. The substantive part of
        Section 54(3) deals with the quantum of credit which is
        amplified by three attributes:                                   H
206         SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A     (a)     it connotes a finite sum and thus a quantum, since a time
              period is prescribed for identifying such quantum by the
              use of the phrase “at the end of any period”;
      (b)     Section 54(3) needs to be read contextually with sub-
              Sections (4), (5) and (6) of Section 49 and Rule 86(3) and
B             Rule 89(3); and
      (c)     Both the GST Council and the Union Government also
              understood that the quantum of refund was the entire
              unutilised ITC and not only ITC accumulated on account
              of input goods. This is evident from Notification No. 5/2017
C             dated 28 June 2017. If the exception contemplated in clause
              (ii) of the first proviso to Section 54(3) contemplates denial
              of the entire basket of unutilised ITC (as argued by the
              State) a fortiori the first part of clause (ii) should be
              presumed to include refund of the entire basket of unutilised
              credit. This is because unless the first part of clause (ii) did
D             not entitle refund of the entire basket of ITC, carving out
              an exception for denial of the entire basket of ITC in the
              latter part would be absurd.
      (vii)   The expression ‘claim’ means a demand made of right,
              calling upon another to pay something which is due.
E             Accordingly, a claim in the context of Section 54(3) is a
              demand for enforcement of a right of refund which becomes
              due. The entitlement to the right is not through the process
              of allowance of the claim but instead, the enforcement of
              the right is through the process of allowance. The
F             entitlement to the right of the entire basket of credit accrues
              from the substantive provision and its enforcement happens
              through the proviso;
      (viii) The expression ‘allowed’ should be interpreted to mean
             verification of the claim and its sanction. Allowed cannot
G            mean the ‘creation of an entitlement’ or else the main
             provision of Section 54(3) would become redundant;
      (ix)    The phrase “wholly on account of” is conspicuous by its
              absence in proviso to Section 54(3);

 (x)     The absence of the word ‘any’ in the proviso is not fatal.       A
         Despite the absence of ‘any’, the words “unutilised ITC”
         refer to credit on goods and services both;
 (xi)    The proviso to Section 54(3) merely prescribes the condition
         and does not deal with the quantum of refund since the
         quantum is prescribed by the substantive provision. The          B
         proviso is not an exception to the substantive part since it
         makes a reference to the substantive condition to be
         satisfied. Both must be construed harmoniously. Thus, the
         main provision of Section 54(3) confers an entitlement to
         the refund of the entire unutilised ITC and the proviso only
         seeks to provide the condition and not to obliterate the main    C
         provision. The better view is that the entitlement is created
         of the quantum of refund by the main provision while the
         proviso only indicates the conditions to be satisfied;
 (xii)   The convergence of credit takes place at the stage of availing
         and not at the stage of utilization;                             D

 (xiii) The CGST Act contemplates that conditions and restrictions
        are two distinct concepts;
 (xiv) If the proviso was meant to deal with the quantum of refund,
       Parliament would have separately carved out a substantive          E
       provision for zero rated supplies and a separate provision
       for domestic supplies. Since that has not been done, both
       cases derive their entitlement to refund of unutilised ITC
       through the substantive provision;
 (xv) Section 54(3) is not akin to an exemption but is aimed at           F
      achieving tax neutrality;
 (xvi) Reliance on the decision of the nine judge Bench in Mafatlal
       Industries Limited v. Union of India (supra) is out of
       context since what is being claimed as a refund is not
       contrary to the statutory drill, but a refund through an
                                                                          G
       appropriate construction of the statute;
 (xvii) The main submissions, in summation, are that:
 (a)     The expression ‘input’ in the proviso if read contextually,
         and not by the strict statutory definition, would cover both
         input goods and input services;                                  H
208         SUPREME COURT REPORTS                        [2021] 15 S.C.R.


A     (b)     Grammatically ‘input’ covers labour and material and is
              opposite to ‘output’;
      (c)     Use of the word “output supplies” as opposed to the defined
              expression “outward supplies” (Section 2(83)) emphasises
              the legislative intent to use common parlance words;
B     (d)     The substantive part of Section 54(3) should be construed
              to provide for the quantum of refund of the entire basket of
              credit and the proviso should be construed merely as a
              threshold condition that an “inverted duty structure” should
              exist qua goods;
C     (e)     If the above propositions are not acceptable, there would
              be an invidious discrimination between input goods and input
              services violating Articles 14 and 19; and
      (f)     The only way to save the provision in such a case is by (i)
              reading down the word “input” in the proviso to include
D             both goods and services or (ii) interpreting the proviso as
              laying down conditions and the quantum of refund being
              prescribed by the main part of Section 54(3); or (iii) striking
              down/severing the offending portion;
      (xviii) The doctrine of reading down the words of the statute to
E             save its constitutional validity also includes reading up. If
              two interpretations are possible, the one which ensures that
              the provision is constitutionally valid must be adopted. Even
              otherwise, if the phrase “on inputs being higher than rate of
              tax on output supplies” is struck down, the impermissible
F             classification between input goods and input services can
              be severed, thereby enlarging the class. Under such
              circumstances Section 54(3) as re-cast should read as
              follows:
              “(3) Subject to provisions of Sub-section 10, a registered
              person may claim refund of any unutilized input tax credit at
G
              the end of any tax period:-
              PROVIDED THAT no refund of unutilized input tax credit
              shall be allowed in cases other than-
              (i) Zero rated supplies made without payment of tax;

        (ii) Where the credit has accumulated on account of rate          A
             of tax (other than nil rated or fully exempt supplies),
             except supplies of goods or services or both as may be
             notified by the Government on the recommendations
             of the Council.”
 (xix) All registered persons demanding refund on account of              B
       inverted duty structure for input goods and input services
       form a part of the same class and seek equality of privileges
       in terms of Article 14:
 (a) Class legislation
 i.     The class consists of all registered persons possessing           C
        unutilised ITC whether or not they are engaged in domestic
        supplies or exports;
 ii.    The species consists of (i) exporters and (ii) domestic
        suppliers where unutilised credit arises due to an inverted
        duty structure;                                                   D
 iii.   Discrimination inter se the species or sub-species of the
        same class would be a class legislation which is hit by Article
        14;
 iv.    To form a part of the same class, the claimant’s position
                                                                          E
        should be substantially similar or in like circumstances, and
        conditions need not be identical; and
 v.     In order to ascertain whether the persons are similarly placed
        one must look beyond classification and into the purpose of
        the law.
                                                                          F
 (xx) Goods and services, though defined separately, are treated
      substantially in a similar manner in several aspects both in
      the Constitution and in the CGST Act;
 (xxi) In examining discriminatory treatment, it is the real effect
       of the provision which must be considered:                         G
 (a)    The real effect of the provision is to create an economy
        which does not perpetuate a harmonized structure of GST
        or a harmonized national market for goods and services,
        which is contrary to the constitutional object of GST as
        provided in Article 279A(6); and                                  H
210         SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A     (b)     The effect that goods are tangible while services are
              intangible does not bear any reasonable relation to the object
              of the legislation or to Article 279A(6). According to the
              submission, equal laws in respect of refunds of taxes in
              cases involving an inverted duty structure would have to be
              applied to everyone in the same situation whether dealing
B
              in input goods or input services. Since the purpose of GST
              is to achieve tax neutrality, equivalence and anti-profiteering,
              their position is substantially the same. The taxable event,
              person, measure of tax, machinery, penal and prosecution
              provisions are substantially the same. Hence the denial of
C             the privilege of refund to input services is arbitrary. The
              classification which is found to be valid in a given frame of
              reference may be invalid in a different frame. From a
              revenue harvesting perspective, goods and services may
              be treated as different. However, from the perspective of
              neutrality and achieving a true consumption tax, goods and
D
              services cannot be treated differently;
      (xxii) The limitation on the power of judicial review of tax
             legislation on grounds of ‘wide latitude’ is subject to
             exception. The submission is that after treating tax on input
             goods and input services in an identical fashion by granting
E            credit (to achieve neutrality) and making the entire credit
             as a part of homogeneous basket, granting refund to input
             goods and not to input services (from that basket) is a
             colourable device to set at naught the doctrine of neutrality.
             The State having reduced the rate of tax on output supplies
F            (leading to an inverted structure) the intent behind the refund
             was to reduce the tax burden on the consumer. Denying
             refund on input services would lead to an indirect impact
             on the very consumer that the State wanted to benefit in
             the first place. Moreover, the State has made no distinction
             between input goods and input services at the time of granting
G            credit, thereby declaring an intent to achieve tax neutrality.
             The denial of refund on input services obliterates that intent
             and runs contrary to the purpose of the legislation; and
      (xxiii) Denial of interest in the case of input services would be an
              unreasonable restriction and would not be saved by Article
H             19(6).

      16. Mr Arvind Datar, learned Senior Counsel19 urged the following            A
submissions:
          (i) An interpretation of Section 54(3) first proviso (ii) which leads
              to disallowance of credit on input services is impermissible
              as, firstly, Articles 269A and 279A introduced by the One
              Hundred and First Constitutional Amendment seek to                   B
              harmonise goods and services and remove the cascading effect
              of taxes. Secondly, the Statement of objects and reasons
              associated with the constitutional amendment and the Bill
              introducing the CGST Act emphasised the need to treat goods
              and services as one combined category. The concept of one
              nation one tax introduced by GST laws cannot be ignored              C
              only at the time of refund;
          (ii) The proviso to Section 54(3) speaks only of categories of
               cases where refund would be available. It does not speak of
               a restriction on the quantum of refund. This is for the following
               reasons:                                                            D

             (a) The quantum is determined by the main sub-section (3),
                 which speaks of “refund of any unutilised input tax
                 credit”;
             (b) The first proviso employs the word “cases” [“no refund            E
                 of unutilised input tax credit shall be allowed in cases
                 other than”] thus making it clear that it only lists categories
                 of cases, and does not deal with quantum of credit;
             (c) The first proviso does not mention “credit to the extent
                 of” or “credit of an amount equal to” or any other such           F
                 wording indicative of quantum;
             (d) Where the legislature intended to advert to the quantum,
                 it has used the words “amount claimed as refund” in the
                 4th proviso – such is not the phrase employed in the first
                 proviso;
                                                                                   G
             (e) The second and third provisos too refer only to ‘cases’ –
                 it is thus clear that first, second and third provisos are
                 intended to deal with cases and are in nature of conditions,
                 while it is only the fourth proviso which adverts to the
19
     Appearing in SLP (Civil) No 589 of 2020                                       H
212   SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A         quantum and there again not to restrict the quantum but
          only to refer to the amount claimed as refund under the
          main sub-section (3); and
      (f) It has been the Union Government’s case that every word
          has been carefully chosen in Section 54(3) first proviso
B         (ii). It follows that where the provision speaks the language
          of categories (i.e. ‘cases’) and not the language of
          quantum (i.e. ‘amount’), it cannot be read as any
          restriction of quantum.
      (iii) The word ‘inputs’ in the first proviso (ii) of Section 54(3)
C           refers to the aggregate of goods and services that are
            used in output supplies. In the context of the first proviso
            (ii), the word ‘inputs’ has not been used to refer only to
            input goods. The word employed in the proviso is “input(s)”
            whereas definition of ‘input’ under Section 2(59) refers to
            goods alone;
D
      (iv) The accumulation (of ITC) is because the total GST on
           all the inputs (goods or services or both) is more than the
           GST payable on the output supplies. The reference is to
           all the inputs used to produce the output supplies;

E     (v) The word “inputs” in Section 54(3) first proviso (ii) cannot
          be restricted to goods because the CGST Act/ SGST Act
          treats goods as services. For instance, transfer of right in
          goods without transfer of title is deemed as “Supply of
          Services” as per Clause 1(b) of Schedule II, which reads
          as follows:
F
         “b. any transfer of right in goods or of undivided share in
         goods without the transfer of title thereof, is a supply of
         services;”
      (vi) Similarly, “Works Contract” as defined in Section 2(119)
           of the CGST Act is deemed as per Clause 6(a) of Schedule
G
           II as “Supply of Services” although it involves the supply
           of goods. Section 2(119) and the relevant portion of
           Schedule reads thus:
            “Section. 2(119) “works contract” means a contract
            for building, construction, fabrication, completion,

            modification, repair, maintenance, renovation, alteration
            or commissioning of any immovable property wherein
            transfer of property in goods (whether as goods or in
            some other form) is involved in the execution of such
            contract”
                                                                         B
 Clause 6(a) of Schedule II provides:
 “6. Composite supply
 The following composite supplies shall be treated as a supply of
 services, namely:—
                                                                         C
 works contract as defined in clause (119) of section 2.”
 (vii)   Further, Article 366(29A) of the Constitution, which provides
         for tax on sale or purchase of goods and which treats six
         kinds of supplies as deemed sales of goods, pertains to and
         is part of the erstwhile Entry 54 of List II which deals only   D
         with goods. Article 366(29A) reads as follows:
         “(29A) tax on the sale or purchase of goods includes
         (a) a tax on the transfer, otherwise than in pursuance of a
             contact, of property in any goods for cash, deferred
             payment or other valuable consideration;                    E
         (b) a tax on the transfer of property in goods (whether as
             goods or in some other form) invoked in the execution
             of a works contract;
         (c) a tax on the delivery of goods on hire purchase or any
             system of payment by instalments;                           F

         (d) a tax on the transfer of the right to use any goods for
             any purpose (whether or not for a specified period) for
             cash, deferred payment or other valuable consideration;
         (e) a tax on the supply of goods by any unincorporated          G
             association or body of persons to a member thereof for
             cash, deferred payment or other valuable consideration;
         (f) a tax on the supply, by way of or as part of any service
             or in any other manner whatsoever, of goods, being
             food or any other article for human consumption or
                                                                         H
214         SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A                 any drink (whether or not intoxicating), where such
                  supply or service, is for cash, deferred payment or other
                  valuable consideration, and such transfer, delivery or
                  supply of any goods shall be deemed to be a sale of
                  those goods by the person making the transfer, delivery
                  or supply and a purchase of those goods by the person
B
                  to whom such transfer, delivery or supply is made;”
      (viii) Chapter V (Section 16 to 21) of the CGST Act does not
             make any distinction between credit of input tax on goods
             or services. Under Section 17 of the CGST Act, the input
             tax on both the goods and services used in exempt supplies
C            or other classes of supplies specified therein, are not
             permitted to be availed as ITC. The remaining/ balance
             input tax is eligible to be availed as ITC, which remains in
             the electronic credit ledger of the taxpayer. After utilizing
             such ITC in terms of Section 49 of the CGST Act (towards
D            output GST on supply of goods or services or both),
             which too makes no distinction between ITC accumulated
             on account of input goods or input services, the balance is
             to be refunded in accordance with Section 54(3) of the Act.
             The relevant portion of Section 49 reads thus:
E             “49. […]
              (6) The balance in the electronic cash ledger or electronic
              credit ledger after payment of tax, interest, penalty, fee or
              any other amount payable under this Act or the rules made
              thereunder may be refunded in accordance with the
F             provisions of section 54’’
      (ix)    There is no distinction between ITC on goods or services
              either at the time of availing or taking of the credit or at the
              time of utilization of credit. Therefore, it could not have
              been the intention of the Parliament to differentiate between
G             the two only at the time of refund in the case of an inverted
              duty structure envisaged under clause (ii) to the first proviso
              to section 54;
      (x)     Without prejudice to the above submissions and assuming
              that the words “inputs” means only input goods and not
              input services, it is stated that even proceeding on the basis

             that the use of the words “on account of” suggests the              A
             requirement of a causal relationship between the higher rate
             of input goods and the accumulation of credit, once such a
             relationship is present, then the entire accumulation is
             available as refund, rather than just the portion relatable to
             input goods. To elaborate:
                                                                                 B
      (a)    Parliament did not state “the credit has accumulated solely/
             only/entirely on account of rate of tax on inputs being higher
             than the rate of tax on output supplies.”;
      (b)    Thus, all that is required is that there is accumulation and
             that the tax on input goods is higher than the output supplies.     C
             If these two criteria are met, it follows logically that at least
             some portion of the accumulation would be on account of
             the higher rate of input services; and
      (c)    Thereupon, the entire accumulation would be available as
             refund in line with the main sub-section (3); and                   D
      (xi)   The impugned notifications/delegated legislation, Notification
             No. 21/2018-CT (amending Rule 89(5)) dated 18 April 2018
             and Notification No. 26/2018 (retrospectively amending Rule
             89(5)) dated 13 June 2018, by disallowing the refund of
             ITC of tax on input services in an inverted duty structure          E
             scenario is not only ultra vires Section 54(3) proviso but
             also beyond the scope of powers of the delegate i.e. the
             Central Government, because such a restriction is a typical
             policy change which could not have been done through a
             delegated legislation.
                                                                                 F
       17. Appearing on behalf of intervenor, Mr G Natarajan, in the
course of his submissions urged (for the purpose of his submissions) that
he does not dispute the position that under Section 54(3) read with rule
89(5), refund of ITC accumulating only on account of “input goods” is
eligible for refund and the credit accumulated on input services is not
entitled for refund. Based on this hypothesis, the submissions of the            G
learned counsel are thus:
      (i)    The formula which has been prescribed in Rule 89(5) seeks
             to identify the quantum of ITC availed on inputs attributable
             to the outward supplies having an inverted rate structure.
             From the quantum of ITC on inputs, the tax payable by the           H
216                SUPREME COURT REPORTS                        [2021] 15 S.C.R.


A                    supplier on the supplies having an inverted rated structure
                     is reduced to arrive at the quantum of the credit
                     accumulating on account of the inverted rate structure,
                     which is available for refund;
            (ii)     In the formula which is prescribed under Rule 89(5), while
B                    reducing the “tax payable on such inverted rated supply of
                     goods or services” the tax payer should be allowed to first
                     utilise the ITC accumulated on account of input services,
                     which is otherwise not eligible for refund;
            (iii)    If the formula prescribed under Rule 89(5) is not read down
C                    in this manner, it will lead to gross inequality between
                     taxpayers having only inverted rated supplies and taxpayers
                     who also have other supplies; and
            (iv)     The formula in Rule 89(5) should hence be read down by
                     stipulating that while calculating the refund entitlement as
D                    the difference between Net ITC and tax payable on such
                     supplies having inverted rated structure, the tax payable
                     after utilising the ITC availed on input services attributable
                     to inverted rate supplies for payment of the tax should be
                     reckoned.

E           18. During the course of his oral submissions Mr Natarajan further
      elaborated on the above submissions by urging that
            (i) Rule 89(5) suffers from the vice of treating unequals equally.
                This happens because a discrimination results between
                assessees who have only inverted rated supplies and those
F               who have other supplies;
            (ii) ITC is available both on input goods and input services;
            (iii) At the end of every tax period, it is possible to note how
                  much ITC has arisen from input goods or input services.
                  However, once a credit in the electronic ledger is utilised, it is
G                 not possible to bifurcate what remains between input goods
                  and input services;
            (iv) In the above backdrop, the manufacturer should be allowed
                 to utilise the ITC on input services first for the payment of
                 taxes; and

         [DR DHANANJAYA Y CHANDRACHUD, J.]

       (v) The formula, as it stands, presumes that the outward tax                A
           liability is paid out of the ITC accumulated only on account of
           input goods. Thus, what is granted by the statute in Section
           16 is indirectly taken away by the formula prescribed in the
           rule. Thus, an order of utilization of credit should be provided
           for payment of taxes to avail of credit on input services. In
                                                                                   B
           other words, in the formula in Rule 89(5) the following words
           should be read in at the end: “after utilising the input tax credit
           on input services pertaining to such inverted rate supply of
           goods and services.”
     19. Appearing for another intervenor20, Mr Shraff, learned Counsel
submitted that-                                                                    C

       (i)   If the Explanation (a) to Rule 89(5) is ultra vires Section
             54(3), unutilised ITC should include capital goods in addition
             to input goods and input services;
       (ii) The electronic ledger makes no distinction between input               D
            goods and input services. The credit arises under integrated
            tax, central tax and state tax. The electronic ledger represents
            a collective credit of input goods, input services and capital
            goods;
       (iii) The inequality arises because small and medium enterprises            E
             (SMEs) with one product, facing an inverted rate structure,
             would get a lesser amount while availing refund whereas
             large companies with multiple products would get refunds
             violating Article 19(1)(g); and
       (iv) The retrospective amendment to Rule 89(5) takes away                   F
            vested or accrued rights.
      20. Mr Uchit Sheth, learned Counsel21 has urged the following
submissions:
       (i)    Once tax credit is claimed and credited into the electronic
              credit ledger, it forms a consolidated pool of credit, making        G
              it impossible to segregate into credit for input goods and
              credit for input services. Hence, it is not possible to ascertain

A              the source of unutilized ITC. The proviso to Section 54(3)
               only lays down a condition precedent for claiming ITC and
               once the condition is fulfilled, then refund is admissible on
               the entire amount of unutilized input ITC;
      (ii)     The amended formula in Rule 89(5) stipulates maximum
B              refund permissible by deducting output tax from the Net
               ITC qua inputs goods. In other words, it is presumed that
               output tax is first adjusted against ITC pertaining to input
               goods and thereafter qua input services. There is no basis
               for such hierarchy in utilization of tax credit and the anomaly
               arises because of an incorrect interpretation of Section 54(3)
C              of the Act by the rule making authority;
      (iii)    Section 49(6) of the Act provides that the balance in the
               electronic cash ledger or electronic credit ledger after
               payment of tax, interest, penalty, fee or any other amount
               payable is to be refunded in accordance with Section 54.
D              The legal obligation is to refund the balance in the ledger if
               the conditions specified in Section 54 are fulfilled. There is
               no legal basis for the artificial dissection of such a balance;
      (iv)     If the rate of tax on inputs is higher than the rate of tax on
               output supplies, the entire unutilized ITC is “on account” of
E              such circumstance and the entire balance of tax credit is
               required to be refunded. The expression ‘on account of’
               cannot be read to mean ‘to the extent of’ particularly when
               it is not possible to compute the unutilized ITC attributable
               to input goods or services;
F     (v)      There are two different connotations of the term ‘input’.
               The first distinguishes it as goods vis-a-vis services while
               the second distinguishes it from output. The expression
               ‘input tax’ and ‘input tax credit’ have been defined to include
               tax in respect of both goods as well as services and there is
G              no phrase called “input service tax credit”. The expression
               ‘inputs’ in the proviso to Section 54(3) has been used in the
               second sense to distinguish it from output; and
      (vi)     GST is a destination-based consumption tax and the
               imposition of the tax is on supply. A supplier is liable to pay
               tax only to the extent it is payable on the output supply of

                 goods or services and the refund of excess balance of input          A
                 of ITC under inverted duty structure is a means to achieve
                 this end. If the excess tax credit is not refunded, the tax
                 liability of the supplier will be in excess of the liability fixed
                 by the charging section and such interpretation should be
                 avoided.
                                                                                      B
        21. Dr Arvind Poddar, learned Counsel appearing on behalf of the
respondents22, urged that the respondents are in the business of providing
dyeing and printing services for textile industries. For job work operations,
they procure input goods (such as chemicals, stationeries and colours)
and for providing outward supplies, they also avail of input services such
as contract labour, consultancies, repairs of plants and machinery. The               C
rate on outward supply of job work on textile fabrics is 5 per cent, while
the rate on input goods and the rate on input services is 12 per cent /18
per cent. Thus, most of the input goods and input services attract a
higher rate of GST compared to rate of GST applicable on the outward
supply which is 5 per cent. The inverted duty structure results where the             D
rate of GST on inverted supplies is higher than the outward supplies. As
a result, over a period of time, credit gets accumulated in the electronic
credit ledger. In this backdrop, the following submissions have been urged:
          (i)    Clause (ii) to the first proviso of Section 54(3) merely
                 prescribes the eligibility conditions subject to which a refund      E
                 of unutilised ITC could be made. The main part of Section
                 54(3) allows for a refund of any unutilised ITC subject to
                 the satisfaction of two conditions – either that the assessee
                 is making zero rated supplies without payment on taxes or
                 where the credit is getting accumulated on account of the
                 rate of tax on inputs being higher than the rate of tax on           F
                 output supplies. Clause (ii) of the first proviso merely
                 prescribes a condition of eligibility subject to which refund
                 of unutilised ITC could be made;
          (ii)   Rule 89(5) while providing a procedure for computing refund
                 under Section 54(3) imposes an artificial restriction which          G
                 has not been prescribed in the main statute and is patently
                 arbitrary and illegal. Section 49 allows credit utilization
                 irrespective of whether it is out of input goods or input

A                   services. On the other hand, Rule 89(5) artificially restricts
                    the credit by initiating the formula under which duty can be
                    paid out of credit on input goods and input services only
                    and hence the credit of input services will keep on
                    accumulating. Rule 89(5) must allow the taxpayers to utilise
                    and make payment through input services first and then the
B
                    balance through credit on inputs; and
            (iii)   It is paradoxical that while on the one hand the definition of
                    net ITC has been amended to exclude ITC availed on input
                    services, on the other hand, turnover of inverted supply of
                    services and tax payable on such inverted rated supply of
C
                    services has been included in the formula for calculating
                    the maximum amount of refund.
            D.3 Rejoinder by Union of India
            22. In response to the submissions of the assessees, Mr N
D     Venkataraman, the learned ASG, has submitted the following propositions:
            (i)     The submission of the respondents that Article 279A(6) of
                    the Constitution mandates a harmonised structure of GST
                    and obligates parity of treatment amongst goods and services
                    is misplaced for the following reasons:
E
            (a)     Article 279A(6) does not compel parity of treatment
                    between goods and services. In fact, Article 366(12) deals
                    with the definition of ‘goods’, Article 366(26A) deals with
                    the definition of ‘services’ and Article 366(12A) defines
                    ‘goods and services’. Thus, goods and services are identified
F                   as two distinct aspects;
            (b)     Article 279A deals with the GST Council. The purpose of
                    Article 279A(6) is to ensure that the GST Council, while
                    discharging its function, is guided by the need for a
                    harmonised structure. Thus, the term ‘harmonised’ or,
G                   harmony in this context would mean uniformity, consistency,
                    shared values and responsibilities between the Union
                    Government and State Governments. The essence of Article
                    279(A)(6) is promotion of cooperative federalism;

 (c)     If the interpretation of the respondents is accepted, it would    A
         render Article 279A(4) otiose as it allows the GST Council
         to make recommendations including rates and floor rates
         with bands of GST.
 (ii)    Registered assessees having unutilised ITC do not form a
         distinct and separate class. Unutilised ITC can accumulate        B
         on account of huge discounts on output supplies of goods
         or services; as a business strategy to indulge in predatory
         pricing; loss of business resulting in undervaluation of goods;
         an Act of God; and inverted duty structure on account of
         inputs or input services, among other reasons . Thus,
                                                                           C
         although registered assessees accumulating unutilised ITC
         constitute one category, it has numerous species. Parliament
         is entitled to choose the species out of the category and
         grant concessions or benefits. This would amount to treating
         equals equally, and unequals unequally;
                                                                           D
 (iii)   The doctrines of equivalence, neutrality or secondary stage
         cascading effect are inapplicable and should not be used to
         read in grant of refund for unutilised ITC on input services.
         Although the stated goal of the doctrines may be
         convergence of a destination-based tax, policy issues as to
         how to achieve the stated goal must be left to the discretion     E
         of the Union Government and the State Governments. The
         level, type and time frame to achieve a complete
         convergence is a policy issue which cannot be subject to
         judicial review;
 (iv)    After the ITC on account of both inputs and input services        F
         is booked into an electronic ledger, it forms a homogenous
         nucleus and the source of the ITC (that is whether it arises
         from input or input services) cannot be determined. Thus,
         the formula provided in Rule 89(5) is necessary to make
         such a bifurcation; and
                                                                           G
 (v)     Prior to the enactment of GST, MODVAT/CENVAT Rules
         contained formulae to determine the quantum of eligibility
         of credit. Similarly, to legally dissect the homogenous
         unutilised ITC, a formula may be resorted to determine
         eligibility, restrictions, or refunds.

A              E Constitutional Scheme of GST
             23. The idea which permeates GST legislation globally is to impose
      a multi stage tax under which each point in a supply chain is potentially
      taxed. Suppliers are entitled to avail credit of tax paid at an anterior
      stage. As a result, GST fulfils the description of a tax which is based on
B     value addition. Value addition is intended to achieve fiscal neutrality and
      to obviate a cascading effect of taxation which traditional tax regimes
      were liable to perpetuate. In a sense therefore, the purpose of a tax on
      value addition is not dependent on the distribution or manufacturing model.
      The tax which is paid at an anterior stage of the supply chain is adjusted.
      The fundamental object is to achieve both neutrality and equivalence by
C
      the grant of seamless credit of the duties paid at an anterior stage of the
      supply chain.
             24. The State VAT legislation in India represented a significant
      stage in the evaluation of fiscal legislation based on the principle of value
      addition. In All India Federation of Tax Practitioners v. Union of
D     India23, this Court, speaking through a two judge Bench, noted the
      principle that VAT is a consumption tax as it is borne by the consumer.
      The Court observed that with its increasing importance in the economy,
      the service sector is “occupying the centre stage of the Indian economy”.
      As economists postulate, there is no distinction between consumption of
E     goods and consumption of services both of which satisfy human wants
      and needs. The Court underscored that service tax is a destination-based
      consumption tax, not a charge on business but on the consumer of the
      service.
             25. Though the erstwhile regime recognised the principle of value
F     addition-based consumption taxes, there was an absence of a seamless
      flow of credit, particularly between Central and State levies. The
      background material antecedent to the adoption of the constitutional and
      legal structure underlying GST in the country indicates the importance
      which was ascribed to developing a tax regime which would achieve a
      continuous chain of set-off from the original producer and service
G     provider’s point up to the retailer’s level in the supply chain and eliminate
      the burden of cascading tax effects. Thus, the first discussion paper on
      GST in India published by the Empowered Committee of State Finance
      Ministers on 10 November 2009 emphasised that :

    UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                             223
        [DR DHANANJAYA Y CHANDRACHUD, J.]

       “1.14 … In the GST, both the cascading effects of CENVAT and            A
      service tax are removed with set-off, and a continuous chain of
      set-off from the original producer’s point and service provider’s
      point upto the retailer’s level is established which reduces the
      burden of all cascading effects. This is the essence of GST, and
      this is why GST is not simply VAT plus service tax but an
                                                                               B
      improvement over the previous system of VAT and disjointed
      service tax.”
       26. The Statement of Objects and Reasons appended to the
Constitution (One-Hundred and Twenty-Second Amendment) Bill 2014
which eventually became the Constitution (One Hundred and First
Amendment) Act 2016 postulates that GST shall replace a number of              C
indirect taxes levied by the Union Government and the State Governments.
The object was to introduce a goods and service tax which would fulfil
two fiscal priorities namely, (1) removing the cascading effect of taxes;
and (2) providing for a common national market for goods and services.
An extract from the Statement of Objects and Reasons is set out below:         D
      “The Constitution is proposed to be amended to introduce the goods
      and services tax for conferring concurrent taxing powers on the
      Union as well as the States including Union territory with Legislature
      to make laws for levying goods and services tax on every
      transaction of supply of goods or services or both. The goods and
                                                                               E
      services tax shall replace a number of indirect taxes being levied
      by the Union and the State Governments and is intended to remove
      cascading effect of taxes and provide for a common national market
      for goods and services. The proposed Central and State goods
      and services tax will be levied on all transactions involving supply
      of goods and services, except those which are kept out of the            F
      purview of the goods and services tax.”
       27. Now, it is in this backdrop that it becomes necessary to advert
to the constitutional amendment and the resulting legislation. The One
Hundred and First Amendment to the Constitution is a watershed
moment in the evolution of cooperative federalism. Since its origin, the       G
Constitution contained a three-fold distribution of legislative power. Under
Article 246, the subjects of legislation enumerated in the Union List of
the Seventh Schedule were assigned to Parliament, those in the State
List were assigned exclusively to the States and those in the Concurrent
List were assigned both to Parliament and the States with precedence
to Parliament under the provisions of Article 254.                             H

A            28. To illustrate, Entry 84 of the Union List provided for duties of
      excise on tobacco and other goods manufactured or produced in India
      except – (a) alcoholic liquors for human consumption; and (b) opium,
      hemp and other narcotic drugs and narcotics. Entry 54 of the State List
      provided for taxes on sale or purchase of goods other than newspapers
      subject to Entry 92A of the Union List which provided for taxes on the
B
      sale or purchase of goods other than newspapers in the course of
      interstate trade or commerce. Entry 97, the residual entry of the Union
      List subsumed within it among other subjects, taxes not mentioned in the
      Union, State or Concurrent List, thereby bringing with its ambit the notion
      of ‘rag-bag’ legislation. The field contemplated by the erstwhile Entry
C     83 of the Union List (duties of customs including export duties) or Entry
      97 did not travel into the area of trading. State legislation in the area of
      sales tax and VAT defined the ambit of the expression ‘inputs’, ‘capital
      goods’ and ‘input tax credit’.
             29. The One Hundred and First Constitutional Amendment brought
D     about a significant merger by contemplating a fiscal umbrella
      comprehending GST. Article 246A was adopted in terms of which,
      notwithstanding anything contained in Article 246 and Article 254,
      Parliament and (subject to Clause (2)), the State Legislature of every
      State have the power to make laws with respect to GST imposed by the
      Union or by the State under clause (2) of Article 246A24. Parliament has
E     the exclusive power to make laws with respect to goods and services
      tax where the supply of goods or of services, or both takes place in the
      course of inter-State trade or commerce. With the enactment of the
      One Hundred and First Constitutional Amendment, Entry 84 of the Union
      List has been restructured to incorporate duties of excise on the following
F     goods manufactured or produced in India, namely –


      24
        “Article 246A. (1) Notwithstanding anything contained in articles 246 and 254,
      Parliament, and, subject to clause (2), the Legislature of every State, have power to
      make laws with respect to goods and services tax imposed by the Union or by such
G     State.
      (2) Parliament has exclusive power to make laws with respect to goods and services
      tax where the supply of goods; or of services, or both takes place in the course of
      inter-State trade or commerce.
      Explanation. – The provisions of this article, shall, in respect of goods and services tax
      referred to in clause (5) of article 279A, take effect from the date recommended by the
H     Goods and Services Tax Council.”

      (a) petroleum crude;                                                      A
      (b) high speed diesel;

      (f) tobacco and tobacco products.
       30. Entry 54 of the State List has been restructured to provide for
taxes on the sale of petroleum crude, high speed diesel, motor spirit
(commonly known as petrol), natural gas, aviation turbine fuel and
                                                                                C
alcoholic liquor for human consumption, other than in the course of inter-
State trade or commerce.
       31. Article 246A has brought about several changes in the
constitutional scheme:
      (i)     Firstly, Article 246A defines the source of power as well         D
              as the field of legislation (with respect to goods and services
              tax) obviating the need to travel to the Seventh Schedule;
      (ii)    Secondly, the provisions of Article 246A are available both
              to Parliament and the State legislatures, save and except
              for the exclusive power of Parliament to enact GST                E
              legislation where the supply of goods or services takes place
              in the course of inter-State trade or commerce; and
      (iii)   Thirdly, Article 246A embodies the constitutional principle
              of simultaneous levy as distinct from the principle of
              concurrence. Concurrence, which operated within the fold          F
              of the Concurrent List, was regulated by Article 254.
      32. The One Hundred and First Constitutional Amendment brought
in amendments to the constitutional dictionary of definitions contained in
Article 366. Clause 12 of Article 366 contained a definition of the
expression “goods” to include all materials, commodities and articles.          G
Clause 12A has been introduced by the amendment to define “goods
and services tax”:
      “Clause (12A) “goods and services tax” means any tax on supply
      of goods, or services or both except taxes on the supply of the
      alcoholic liquor for human consumption”.
                                                                                H
226               SUPREME COURT REPORTS                       [2021] 15 S.C.R.


A           Clause 26A has been introduced to define “services”:
            “Clause (26A) “Services” means anything other than goods”
            ‘Services’, therefore, under the constitutional scheme means
      anything other than goods.
             33. The constitutional scheme embodying GST is facilitated through
B
      the composition of the GST Council under Article 279A. The GST Council
      is to consist of the Union Finance Minister, the Union Minister of State
      in charge of Revenue of Finance; and the Minister In-charge of Finance
      or Taxation or any other Minister nominated by each State Government.
      Clause (4) of Article 279(A) empowers the GST Council to make
C     recommendations to the Union and the States on the aspects
      comprehended in sub-clauses (a) to (h) of Clause (4), which are extracted
      below:
            “[…]
            (a)    the taxes, cesses and surcharges levied by the Union, the
D                  States and the local bodies which may be subsumed in the
                   goods and services tax;
            (b)    the goods and services that may be subjected to, or exempted
                   from the goods and services tax;
            (c)    model Goods and Services Tax Laws, principles of levy,
E                  apportionment of Goods and Services Tax levied on supplies
                   in the course of inter-State trade or commerce under article
                   269A and the principles that govern the place of supply;
            (d)    the threshold limit of turnover below which goods and services
                   may be exempted from goods and services tax;
F
            (e)    the rates including floor rates with bands of goods and
                   services tax;
            (f)    any special rate or rates for a specified period, to raise
                   additional resources during any natural calamity or disaster;
G           (g)    special provision with respect to the States of Arunachal
                   Pradesh, Assam, Jammu and Kashmir, Manipur, Meghalaya,
                   Mizoram, Nagaland, Sikkim, Tripura, Himachal Pradesh and
                   Uttarakhand; and
            (h)    any other matter relating to the goods and services tax, as
                   the Council may decide.”

      Clause (6) of Article 279A stipulates that:                               A
      “(6) While discharging the functions conferred by this article, the
      Goods and Services Tax Council shall be guided by the need for a
      harmonised structure of goods and services tax and for the
      development of a harmonised national market for goods and
      services.”                                                                B
        34. Article 279A(6) indicates that in the discharge of its functions,
the GST Council is to be guided by the need for a harmonised structure
of goods and services tax and the development of a harmonised national
market for goods and services. This emphasis on harmony is crucial to
co-operative federalism. It underscores that in a federal arrangement           C
where the States and Union are converging together for the first time to
adopt the same event for taxation, both sets of partners must be guided
by the over-arching need to preserve harmony. Harmony postulates
balance, an acceptance of mutual co-existence. Clauses (7) to (11) of
Article 279A contain provisions for quorum, procedure and voting. Clause
(9) is a clear indicator of the absence of supremacy either of the Union        D
of the States. Under sub clause (a) of Clause 9, the vote of the Union
Government is to have a weightage of one-third of the total votes cast,
while the votes of all the State Governments together are to have a
weightage of two-thirds of the total votes cast. Every decision of the
Council is to be taken by a majority of not less than three-fourths of the      E
weighted votes of the members present and voting. The principle of
harmony does not postulate exact coincidence in all points of comparison
or reference. Harmony is a postulate of cooperative federalism and is
founded on the principle of mutual co-existence, deference and equality
of the coexisting units.
                                                                                F
      F CGST Act
      F.1 Definitions
      35. While understanding the provisions of Section 54(3), it becomes
necessary to advert to some of the key definitions contained in the CGST
Act.                                                                            G
      Section 2 (52) defines the expression goods in the following terms:
      “goods” means every kind of movable property other than money
      and securities but includes actionable claim, growing crops, grass
      and things attached to or forming part of the land which are agreed
      to be severed before supply or under a contract of supply.”               H
228            SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A            36. The expression ‘goods’ is defined on the basis of a ‘means
      and includes’ formula. Following well-settled principles of statutory
      interpretation, the legislature uses the expression ‘means’ when it intends
      the definition to be exhaustive. The use of the expression ‘includes’ is
      intended to convey an expansive meaning. By using the expression “means
      and includes”, the legislature intends to employ an extensive definition,
B
      incorporating subjects which may not ordinarily fall within the common
      understanding of the expression. Thus, the expression ‘goods’ is defined
      to mean every kind of movable property other than money and securities.
      It also includes certain other items incorporated in the inclusive part
      (“but includes”) of the definition. The expression ‘goods’ is broadly
C     defined. The expression ‘services’ is defined in Section 2(102) in the
      following terms:
            “Section 2(102) “services” means anything other than goods,
            money and securities but includes activities relating to the use of
            money or its conversion by cash or by any other mode, from one
D           form, currency or denomination, to another form, currency or
            denomination for which a separate consideration is charged.
            Explanation: For the removal of doubts, it is hereby clarified that
            the expression “services” includes facilitating or arranging
            transactions in securities.”
E           The expression ‘services’ is thus distinguished from goods since
      the expression means “anything other than goods”.
            37. The definition of the expression ‘input’ is contained in Section
      2(59) which reads thus:

F           “2(59) “input” means any goods other than capital goods used or
            intended to be used by a supplier in the course or furtherance of
            business”
             The expression ‘input’ is thus defined to mean goods other than
      capital goods. The definition however, incorporates a requirement of
      use, actual or intended, by a supplier or in the course or furtherance of
G
      business.
            38. ‘Input service’ is defined in Section 2(60) as follows:
            “input service” means any service used or intended to be used by
            a supplier in the course or furtherance of business;”
H
    UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                              229
        [DR DHANANJAYA Y CHANDRACHUD, J.]

       The definition of “input service” is parallel to that of “input”, with   A
the important distinction that while ‘input’ is defined with reference to
“any goods”, ‘input service’ is defined in relation to “any service”. Both
sets of definitions incorporate the further requirement of use or intended
use by a supplier in the course or furtherance of business.
       39. The expression “input tax” is defined in Section 2(62) :             B
       “Input tax” in relation to a registered person, means the Central
       tax, State tax, integrated tax or Union territory tax charged on any
       supply of goods or services or both made to him and includes—
          (a) the integrated goods and services tax charged on import of
          goods;                                                                C

          (b) the tax payable under the provisions of sub-sections (3)
          and (4) of section 9;
          (c) the tax payable under the provisions of sub-sections (3)
          and (4) of section 5 of the Integrated Goods and Services Tax         D
          Act;
          (d) the tax payable under the provisions of sub-sections (3)
          and (4) of section 9 of the respective State Goods and Services
          Tax Act; or
          (e) the tax payable under the provisions of sub-sections (3)          E
          and (4) of section 7 of the Union Territory Goods and Services
          Tax Act,
      but does not include the tax paid under the composition levy.”
        The expression ‘input tax’ in relation to a registered person means
(i) the Central, State, Integrated or Union Territory tax; (ii) charged on      F
any supply of goods or services or both made to a registered person.
This is followed by an inclusive definition.
       40. The expression ‘input tax credit’ is defined in Section 2 (63):
       “2(63) “input tax credit” means the credit of input tax”                 G
       Evidently, since input tax credit means the credit on input tax, the
definition of the expression ‘input tax’ has to be read into Section 2(63)
in understanding the ambit of the expression ‘input tax credit’. Now,
input tax is the tax charged on the supply of goods or services or both.
Apart from the above definitions there are three other definitions which
                                                                                H
230             SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A     must be noted at this stage. The expression ‘inward supply’ is defined in
      Section 2 (67) in the following terms:
             “2(67) “inward supply” in relation to a person, shall mean receipt
             of goods or services or both whether by purchase, acquisition or
             any other means with or without consideration.”
B            41. The expression ‘output tax’ is defined in the following terms:
             “2(82) “output tax” in relation to a taxable person, means the tax
             chargeable under this Act on taxable supply of goods or services
             or both made by him or by his agent but excludes tax payable by
             him on reverse charge basis”
C
             The expression ‘outward supply’ is defined in Section 2(83) thus:
            “2(83) “outward supply” in relation to a taxable person, means
            supply of goods or services or both, whether by sale, transfer,
            barter, exchange, licence, rental, lease or disposal or any other
D           mode, made or agreed to be made by such person in the course or
            furtherance of business.”
             42. Again, as in the case of inward supply, the expression “outward
      supply” incorporates the supply of goods or services or both. The
      expression “output tax” in other words means tax chargeable under the
      Act on the taxable supply of goods or services or both. The above
E
      definitions fall into three clusters: the first cluster relates to receipt –
      Section 2(62), Section 2(63) and Section 2(67); the second cluster consists
      of outward supply and output tax - Section 2(82) and Section 2(83); and
      the third cluster consists of goods, services, input and input services –
      Section 2(52), Section 2(102), Section 2(59) and Section 2(60).
F
             F.2 Section 16 & Section 49 of the CGST Act
              43. Section 16 is comprised in Chapter V and is titled as ‘input tax
      credit’. The marginal note to Section 16 indicates that the provision relates
      to eligibility and conditions for taking ITC. Sub-Section (1) of Section 16
      is in the following terms:
G
            “16 Eligibility and conditions for taking input tax credit. – (1) Every
            registered person shall, subject to such conditions and restrictions
            as may be prescribed and in the manner specified in section 49, be
            entitled to take credit of input tax charged on any supply of goods
            or services or both to him which are used or intended to be used in

      the course or furtherance of his business and the said amount             A
      shall be credited to the electronic credit ledger of such person.”
      44. Under sub-Section (1) Section 16:
      (i) every registered person shall be entitled to take credit to input
          tax charged on any supply of goods and services or both to
          him;                                                                  B

      (ii) which are used or intended to be used in the course or
           furtherance of his business;
      (iii) subject to such conditions and restrictions as may be
            prescribed; and                                                     C
      (iv) in the manner specified in Section 49.
       45. The amount of input tax credit is to be credited in the electronic
credit ledger of the registered person. Sub-Section (2) spells out the
conditions upon the fulfilment of which the entitlement to the credit of
input tax in respect of any supply of goods or services can be availed.         D
Sub- Section (2) of Section 16 is in the following terms:
      “16. […]
      (2) Notwithstanding anything contained in this section, no registered
      person shall be entitled to the credit of any input tax in respect of
      any supply of goods or services or both to him unless,––                  E

      (a) he is in possession of a tax invoice or debit note issued by a
      supplier registered under this Act, or such other tax paying
      documents as may be prescribed;
      (aa) the details of the invoice or debit note referred to in clause (a)   F
      has been furnished by the supplier in the statement of outward
      supplies and such details have been communicated to the recipient
      of such invoice or debit note in the manner specified under Section

          Explanation.—For the purposes of this clause, it shall be deemed
          that the registered person has received the goods or, as the
          case may be, services-

A               whether acting as an agent or otherwise, before or during
                movement of goods, either by way of transfer of documents of
                title to goods or otherwise;
                (ii) where the services are provided by the supplier to any person
                on the direction of and on account of such registered person.
B           (c) subject to the provisions of section 41, the tax charged in respect
            of such supply has been actually paid to the Government, either in
            cash or through utilisation of input tax credit admissible in respect
            of the said supply; and
            (d) he has furnished the return under section 39:
C
            Provided that where the goods against an invoice are received in
            lots or instalments, the registered person shall be entitled to take
            credit upon receipt of the last lot or instalment:
            Provided further that where a recipient fails to pay to the supplier
D           of goods or services or both, other than the supplies on which tax
            is payable on reverse charge basis, the amount towards the value
            of supply along with tax payable thereon within a period of one
            hundred and eighty days from the date of issue of invoice by the
            supplier, an amount equal to the input tax credit availed by the
            recipient shall be added to his output tax liability, along with interest
E           thereon, in such manner as may be prescribed:
            Provided also that the recipient shall be entitled to avail of the
            credit of input tax on payment made by him of the amount towards
            the value of supply of goods or services or both along with tax
            payable thereon”
F
             46. Section 16(2) indicates that the credit of input tax charged on
      any supply of goods or services, or both, can be availed of by a registered
      person subject to the conditions which are set out in the provisos. Input
      tax, as we have already seen, has been defined in Section 2(62) as tax
      charged on any supply of goods or services or both. The credit of input
G     tax is, therefore, relatable both to the supply of goods and services.
      Whether tax is paid on the supply of goods or services, the recipients
      receive ITC in a similar manner. Taxes on goods and services are
      identifiable, but upon credit to the electronic ledger they form a common
      pool for utilization. Section 16(1) indicates that the manner in which
      input tax credit can be utilized is spelt out in Section 49. Sub- Section (1)
H     of Section 49 provides:

      maintained in such manner as may be prescribed...”
       47. Sub-Section (3) of Section 49 envisages that the amount
available in the electronic cash ledger may be used for making any
payment towards tax, interest, penalty, fees or any other amount payable
under the provisions of the Act or its rules in the manner and subject to
conditions and within such time as is prescribed. Similarly, sub-Section       C
(4) of Section 49 stipulates that the amount available in the electronic
credit ledger can be used for making payment towards output tax under
the CGST Act or under the IGST Act in such manner and subject to the
conditions and within such time as is prescribed. Sub-Section (5) of
Section 49 spells out the priorities according to which the amount of ITC      D
available in the electronic credit ledger can be utilized. Sub Section (6)
of Section 49 is significant and provides as follows:
      “(6) The balance in the electronic cash ledger or electronic credit
      ledger after payment of tax, interest, penalty, fee or any other
      amount payable under this Act or the rules made thereunder may           E
      be refunded in accordance with the provisions of Section 54.”
      48. The provisions of Section 16 and Section 49 indicate the
following position:
      (i)     The ITC in the electronic credit ledger may be availed of
              for making any payment towards output tax under the CGST         F
              Act or under the IGST Act;
      (ii)    The amount available in the electronic cash ledger may be
              used for making any payment towards tax, interest, penalty,
              fees or any other amount payable under the CGST Act or
              its rules;                                                       G
      (iii)   The balance in the electronic cash ledger or electronic credit

              any other amount payable under the Act or rules may be
              refunded in accordance with the provisions of Section 54;
              and                                                              H

A           (iv) Sub Section (6) of Section 49, in other words contemplates
                 a refund of the balance which remains in the electronic cash
                 ledger or electronic credit ledger in the manner stipulated
                 by the provisions of Section 54.
            F.3 Interpretation of Section 54(3) of the CGST Act
B            49. The controversy in the present case turns upon the
      interpretation of Section 54, which is found in Chapter XI titled as
      ‘Refunds’. The marginal note of Section 54 is titled “Refund of Tax”.
      Section 54(1) provides thus:
            “54. (1) Any person claiming refund of any tax and interest, if any,
C           paid on such tax or any other amount paid by him, may make an
            application before the expiry of two years from the relevant date
            in such form and manner as may be prescribed:
             Under sub-Section (1) of Section 54, an application has to be
      made within two years of the relevant date by a person claiming refund
D     of tax and interest (if any, paid on the tax or any other amount paid), in
      such form and manner as prescribed. Explanation 1 to Section 54 is in
      the following terms:
            “Provided that a registered person, claiming refund of any balance
            in the electronic cash ledger in accordance with the provisions of
E           sub-section (6) of section 49, may claim such refund in the return
            furnished under section 39 in such manner as may be prescribed.”
            Sub-Section (3) of Section 54 is in the following terms:
            “Subject to the provisions of sub-section (10), a registered person
            may claim refund of any unutilised input tax credit at the end of
F
            any tax period:
            Provided that no refund of unutilised input tax credit shall be allowed
            in cases other than––
            (i) zero rated supplies made without payment of tax;
G           (ii) where the credit has accumulated on account of rate of tax on
            inputs being higher than the rate of tax on output supplies (other
            than nil rated or fully exempt supplies), except supplies of goods
            or services or both as may be notified by the Government on the
            recommendations of the Council:
H
    UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                               235
        [DR DHANANJAYA Y CHANDRACHUD, J.]

       Provided further that no refund of unutilised input tax credit shall      A
       be allowed in cases where the goods exported out of India are
       subjected to export duty:
       Provided also that no refund of input tax credit shall be allowed, if
       the supplier of goods or services or both avails of drawback in
       respect of central tax or claims refund of the integrated tax paid        B
       on such supplies.”
       50. The submission which was urged by the assessees before the
Gujarat and Madras High Courts, as well as this Court, is that under the
substantive part of Section 54(3), Parliament has contemplated that the
claim of refund may extend to any unutilized ITC. ITC means credit of            C
input tax and since ‘input tax’ is defined with reference to the tax charged
on the supply of goods or services or both, a refund may be claimed not
only of the tax charged on input goods but also input services as a whole.
According to the Revenue, the first proviso to Section 54(3) is a restriction.
On the other hand, assessees have urged that the first proviso sets out
only a condition or provision for eligibility and once it is fulfilled, the      D
refund is available on the entirety of the unutilized ITC including the
credit which is relatable to tax paid on input goods and input services.
        51. The crux of the dispute in the present case pertains to how
sub-Section (3) to Section 54 and Explanation 1 to sub-Section (1) of
Section 54 are to be understood and interpreted. For convenience of              E
analysis, the interpretation of sub-Section (3) of Section 54 can be
distributed in its main tier and the three provisos. The main part of sub-
Section (3) provides that a registered person may claim refund of any
unutilized ITC at the end of any tax period. Tax period is defined in
Section 2(106) as the period for which the return is required to be              F
furnished. While enacting Section 54(3), Parliament has envisaged a
claim for the refund of unutilized ITC by a registered person at the end
of the tax period. The first tier is the main provision of Section 54(3)
which lays down four conditions:
       (i) A claim of refund;                                                    G
       (ii) By a registered tax person;
       (iii) Of any unutilized ITC; and
      (iv) At the end of any tax period, subject to the provisions of sub-
Section (10).
                                                                                 H
236             SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A             52. The second tier is the first proviso. The first proviso begins
      with the expression “no refund of unutilized ITC shall be allowed in
      cases other than” which is followed by clauses (i) and (ii). The opening
      line of the first proviso contains two expressions of significance, namely,
      “no refund shall be allowed” and “in cases other than”. The expression
      ‘allowed’ in the proviso must be contrasted with the expression ‘claim’
B
      in the substantive part of sub-Section (3). A refund can be allowed only
      in the eventualities envisaged in clauses (i) and (ii). The expression ‘other
      than’ operates as a limitation or restriction.
             53. The third tier of sub-Section 54(3) consist of the two clauses
C     of the first proviso which deal with two distinct cases: Clause (i) deals
      with zero-rated supplies made without payment of tax, while Clause (ii)
      deals with credit which has accumulated on account of the rate of tax
      on inputs being higher than the rate of tax on output supplies. Proviso (ii)
      embodies the concept of an inverted duty structure. Proviso (ii) states
      that the refund of unutilized ITC shall be allowed only when the credit
D     has accumulated because the rate of tax of inputs is higher than the rate
      of tax on output supplies. Input, as we have already noted, is defined in
      Section 2(59) to mean goods other than the capital goods. ‘Output
      supplies’ is not defined in the statute. As seen above, Section 16 stipulates
      the eligibility and conditions for availing ITC. ITC accumulates when
E     the credit cannot be utilized either partly or in whole and this may occur
      for a variety of reasons. The credit of ITC may accumulate for several
      reasons. Without spelling out an exhaustive list of circumstances, the
      accumulation may be due to: (a) an inverted duty structure when the
      GST on output supplies is less than the GST on inputs; (b) stock
      accumulation; (c) capital goods; and (d) partial reverse mechanism for
F     certain services. There could be other reasons as well, such as excessive
      discounts or predatory pricing.
             54. The distortion caused by unutilized accumulated ITC was
      noticed before the advent of the GST regime, in the context of the State
      VAT legislation under the erstwhile regime. A White Paper on State-
G     level Value Added Tax by the Empowered Committee of State Finance
      Ministers dated 17 January 2005 contemplated that if any credit remained
      unutilized in a month, it will be carried forward. If even at the end of
      second year there is an excess unadjusted ITC, the same will be refunded:
            “Carrying Over of Tax Credit
H
     UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                                         237
         [DR DHANANJAYA Y CHANDRACHUD, J.]

        2.4 If the tax credit exceeds the tax payable on sales in a month,                  A
        the excess credit will be carried over to the end of next financial
        year. If there is any excess unadjusted input tax credit at the end
        of second year, then the same will be eligible for refund….”
       Based on this, a provision for refund of unadjusted ITC was
inserted in Section 11 of the Gujarat Value Added Tax Act read with                         B
Rule 15(6) of the Gujarat Value Added Tax Rules 200625. When the
GST regime was under discussion, the first discussion paper by the
Empowered Committee of State Finance Ministers published on 10
November 2009 acknowledged the problem of the accumulation of ITC
on account of the rate of input tax being higher than output tax and
suggested that a refund be provided of accumulated ITC. The relevant                        C
extract from the discussion paper dealing with the ‘Salient features of
the GST model’ reads thus:
        “3.2…(vi) Ideally, the problem related to credit accumulation on
        account of refund of GST should be avoided by both the Centre
        and the States except in the cases such as exports, purchase of                     D
        capital goods, input tax at higher rate than output tax etc. where,
        again refund/adjustment should be completed in a time bound
        manner.”
       55. The report of the Joint Committee, Empowered Committee of
State Finance Ministers on Business Process for GST and on Refund                           E
Process published in August 2015 noted that under the proposed GST
law, ITC will be allowed, so as to remove the cascading effect of taxes
and it is the ultimate customer who should bear the burden of taxes.
However, the report noticed that there can be cases where there is an
accumulation of credit due to an inverted duty structure. The report                        F
envisaged that there would fewer rates of taxes and exemptions under

25
  Rule 15
“(6) Where the tax credit (other than tax credit on capital goods) admissible in the year
remains unadjusted against the output tax as per section 11, such amount shall be
refunded not later than expiry of two years from the end of the year in which such tax
credit had become admissible:
                                                                                            G
Provided that the dealer claiming such refund shall have to prove to the satisfaction of
the assessing authority that the purchases of the goods on which such tax credit had
been calculated have been disposed off in the manner referred to in sub-section (3) of
section 11 within the period by which refund under this sub-rule becomes admissible.”
See also, Section 51 of the Maharashtra Value Added Tax Act 2002 read with Rule 60
of the Maharashtra Value Added Tax Rules 2005                                               H

A     GST and hence, the chances of an inverted duty structure would be
      “minimal”. At the same time, it recommended a refund of carried forward
      ITC in the following terms:
            “(H) REFUND OF CARRY FORWARD INPUT TAX CREDIT:
            i) As stated earlier, ITC is allowed to remove cascading and under
B           modern VAT laws, tax is charged on value addition only and tax is
            not charged on tax. It is for this reason that the ultimate consumer
            is liable to bear the tax burden.
            ii) It is noted that the ITC may accumulate on account of the
            following reasons :
C              a) Inverted Duty Structure i.e. GST on output supplies is less
               than the GST on the input supplies;
               b) Stock accumulation;
               c) Capital goods; and
D              d) Partial Reverse charge mechanism for certain services.
            iii) As regards the accumulated ITC attributed to accumulation of
            stock or capital goods, it is recommended that GST Law may
            provide that refund of carried forward ITC may not be allowed
            and such amount would be carried forward to the next tax period
E           (s). The GST Law may provide for appropriate provisions in this
            regard.
            iv) Under the proposed GST law, it is proposed to have fewer
            tax rates and fewer exemptions and therefore it is felt that
            chances of inverted duty structure would not be there or
            would be very minimal. But still there might be a possibility
F
            that ITC may accumulate on account of inverted duty
            structure.
            v) It is recommended that in such case, cash refund may be
            granted after due audit and should be sanctioned only after
            the input tax credit has been matched from the purchase
G           and sales statements filed along with monthly returns. The
            refund would be granted on submission of application. It
            may be mentioned, however, that presently the Centre does
            not grant refund in such cases.…”

        [DR DHANANJAYA Y CHANDRACHUD, J.]

       While enacting Clause (ii) of the first proviso to Section 54(3) in       A
the CGST Act, Parliament, took legislative notice of a specific eventuality
namely “where the credit has accumulated on account of the rate of tax
on inputs being higher than the rate of tax on output supplies”. Parliament
would be cognizant of the fact that ITC may accumulate for a variety of
reasons, of which an inverted duty structure is one situation. Parliament
                                                                                 B
was legislating to provide for a refund and therefore restricted it to the
two situations spelt out in clauses (i) and (ii) of the first proviso. The
opening words of the substantive part of Section 54(3) contemplate a
claim of refund of “any unutilized input tax credit”. Undoubtedly, any
unutilized ITC would include credit on account of tax charged on any
supply of goods or services or both. The opening sentence of Section             C
54(3) provides for (i) a claim of refund by a registered person; (ii) of any
unutilized input tax credit; (iii) at the end of any tax period. But the
impact of the first proviso, as its opening words indicate, is that :
      (i)     “No refund” of unutilized ITC “shall be allowed” “in cases
              other than” (i) and (ii);                                          D
      (ii)    The expression “claim” in the substantive part must be
              distinguished from the phrase “shall be allowed” in the
              opening sentence of the first proviso. Likewise, the
              expression “may claim refund” in the opening part must be
              distinguished from “no refund” in the opening part of the          E
              first proviso;
      (iii)   The impact of the first proviso is that a refund of unutilized
              ITC shall be allowed only in cases falling under (i) and (ii).
              The expression ‘only’ in the previous sentence is not a judicial
              addition to statutory language but follows plainly from the        F
              expressions “no refund” of unutilized ITC shall be allowed
              “in cases other than”;
      (iv)    The expression “in cases other than” is a clear indicator
              that clauses (i) and (ii) are restrictive and not conditions of
              eligibility. A refund, in other words, can be allowed in the       G
              two contingencies spelt out in clauses (i) and (ii) of the first
              proviso;
      (v)     There is a clear distinction between clause (i) and clause
              (ii) of the first proviso: (a) in the case of exports, the
              contingency is zero-rated supplies without any distinction
                                                                                 H

A                    between input goods or input services; (b) in contrast for
                     domestic supplies, clause (ii) relates to the accumulation of
                     credit on account of rate of tax on inputs being higher than
                     the rate of tax on output supplies;
             (vi)    The legislative draftsperson has made a clear distinction
B                    between clause (i) and clause (ii) of the first proviso and it
                     was in this context that the opening words of Section 54(3)
                     have used the expression “may claim refund of any unutilized
                     ITC”;
             (vii)   Explanation 1 to Section 54, while defining the expression
C                    “refund” for the purposes of the section adopts an inclusive
                     definition covering (a) refund of tax paid on zero rated
                     supplies of goods or services or both; (b) refund of tax paid
                     on input goods or inputs services used in making such zero-
                     rated supplies; (c) refund of tax on supply of goods regarded
                     as deemed exports; and (d) refund of unutilized ITC as
D                    provided under sub-section(3) of Section 54; and
             (viii) Explanation 1 indicates that with reference to exports, the
                    legislature has brought within its fold ITC on input goods
                    and input services. In contrast, in the case of domestic
                    supplies it has contemplated refund of unutilized ITC “as
E                   provided under sub-section(3)”. The Explanation is a clear
                    indicator that in respect of domestic supplies, it is only
                    unutilized credit which has accumulated on the rate of tax
                    on input goods being higher than the rate of output supplies
                    of which a refund can be allowed. Clause (ii) of the first
F                   proviso in other words is a restriction and not a mere
                    condition of eligibility.
              56. The fulcrum of the argument of the assessees before the
      Gujarat and Madras High Courts and before this Court is that clause (ii)
      of the first proviso prescribes a condition of eligibility and not a restriction
G     on the entitlement to refund. The entire basket of unutilized ITC, whether
      traceable to goods or services, is in the submission, eligible for refund.
      This submission has been made before the Court on three planes. The
      first plane on which the submission has been urged is that the purpose
      of enacting Section 54(3) was to ensure against a cascading effect or
      ‘sticking’ inputs tax. According to the assesses, the GST regime is a
H     result of a long-standing exercise of legislative preparation in the doctrine
       UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                            241
           [DR DHANANJAYA Y CHANDRACHUD, J.]

of equivalence and tax neutrality. According to the submission, the              A
doctrine of equivalence postulated an equivalence between goods and
services in the VAT regime, which must a fortiori be so under the auspices
of a unified GST legislation which contemplates that businesses are only
pass-through entities. The second plane of the submission is that the
function of the GST Council, as specified in Article 279A(6), is that it is
                                                                                 B
to be guided by the need for a harmonized structure of GST and a
harmonized national market for goods and services. Clause (12A) of
Article 366 provides for the levy of GST on both- goods and services. In
this context, it was urged that in any fiscal regime, there are five essential
components comprising of (a) taxable events; (b) taxable persons; (c)
measure of tax; and (d) rate of tax; and (e) administrative machinery. In        C
all these, it is urged that the CGST makes absolutely no distinction between
goods and services. Section 16 which provides for the utilization of ITC
makes no distinction between goods and services. The pale of the law, it
was urged, applies substantive provisions similarly in the case of goods
as well as services except as regard rates. But as regards rates, it was
                                                                                 D
urged that even within the category of goods, the rates may or do vary.
The legislature, for the first time, introduced anti-profiteering provisions
based on the precept that a reduction in the rate of tax must be passed
on to the consumer. When neutrality was not intended, as in the case of
Section 17(5), a specific provision has been made by the legislature where
the ITC cannot be availed of in those cases. Once the threshold of               E
Section 17(5) is crossed, tax neutrality must, in their submission, be
achieved. Finally, it was also urged that an inverted duty structure arises
in many cases where the rate of tax on output supplies is reduced in
order to fulfil certain objectives guided by public interest such as
encouraging infrastructure development. In this backdrop, it was
                                                                                 F
submitted that where the reduction of the rate of tax on outward supplies
is in pursuance of the policy of the State, the ultimate object of achieving
tax neutrality must be given full effect by fully effectuating a refund
under Section 54(3) by allowing a refund of unutilized ITC, whether
relatable to goods or services.
       57. The submission based on the doctrine of equivalence places            G
reliance on the decision of a three judge Bench of this Court in
Association of Leasing and Financial Service Companies v. Union
of India26. Chief Justice S H Kapadia, speaking for a three judge Bench,
dealt with the validity of the provisions of Sections 65(12) and 65(105)

     2011 (2) SCC 352                                                            H

A     (zm) of the Finance Act 1994, in so far as the said provisions sought to
      levy service tax on leasing and hire purchase. The levy of service tax on
      financial leasing services was challenged as being beyond the
      competence of Parliament by virtue of Article 366(29A) of the
      Constitution. While construing the issue, the Court adverted to the decision
      in All India Federation of Tax Practitioners (supra) and observed:
B
            “Service tax is an economic concept based on the principle of
            equivalence in a sense that consumption of goods and consumption
            of services are similar as they both satisfy human needs. Today
            with the technological advancement there is a very thin line which
            divides a “sale” from “service”. That, applying the principle of
C           equivalence, there is no difference between production or
            manufacture of saleable goods and production of marketable/
            saleable services in the form of an activity undertaken by the
            service provider for consideration, which correspondingly stands
            consumed by the service receiver. It is this principle of equivalence
D           which is inbuilt into the concept of service tax under the Finance
            Act, 1994. That service tax is, therefore, a tax on an activity. That,
            service tax is a value added tax. The value addition is on account
            of the activity which provides value addition, for example, an
            activity undertaken by a chartered accountant or a broker is an
            activity undertaken by him based on his performance and skill.
E           This is from the point of view of the professional. However, from
            the point of view of his client, the chartered accountant/broker is
            his service provider. The value addition comes in on account of
            the activity undertaken by the professional like tax planning,
            advising, consultation, etc. It gives value addition to the goods
F           manufactured or produced or sold. Thus, service tax is imposed
            every time service is rendered to the customer/client. This is clear
            from the provisions of Section 65(105)(zm) of the Finance Act,
            1994.”
             58. The above formulation of the doctrine of equivalence dwelt
G     on the economic rationale underlying the enactment of service tax. The
      economic rationale is based on the equivalence of goods and services,
      both of which are instruments for the satisfaction of human needs. The
      principle recognizes that there is, in economic terms, an equivalence
      between production or manufacture of saleable goods and production of
      marketable and saleable services. The issue before this Court, however,
H
     UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                             243
         [DR DHANANJAYA Y CHANDRACHUD, J.]

is whether an a priori equivalence between goods and services for the           A
purpose of bringing both within a composite tax regime must result in the
conclusion that a refund of unutilized ITC must be made available to
both - input goods as well as input services, disregarding the provision
which has been inserted by the legislature in the present case in the
form of Section 54(3). The answer to this is clear. The Court while
                                                                                B
interpreting the provisions of Section 54(3) must give effect to its plain
terms. The Court cannot redraw legislative boundaries on the basis of
an ideal which the law was intended to pursue.
        59. Sub-Section (6) of Article 279A has provided that while
discharging its functions the GST Council shall be guided by the need for
(a) a harmonised structure of goods and service tax; and (b) the                C
development of a harmonised national market for goods and services. In
emphasizing the need, the constitutional provision reflects a goal, object
and aspiration to be achieved. By emphasizing this, the provision
underscores the vision that the GST Council should bear in mind in the
discharge of its constitutional functions. The constitutional object is         D
however to be realized under the auspices of legislation duly enacted
under the provisions of Article 246A. The GST Council is intended to
function towards the advancement of a harmonised structure for GST
and market for goods and services. Contemporary doctrine would suggest
that these objects of the fiscal regime may be furthered by bearing in
mind (i) the doctrine of equivalence; (ii) the doctrine of neutrality; and      E
(iii) the need of obviating secondary stage cascading effects. The
realpolitik of tax policy and governance in the real world may not always
match up to ideals. In an ideal tax regime, with a uniform rate of taxes
on inputs goods, input services and outward supplies, the chance of
accumulating unutilized ITC as a result of an inverted rate structure           F
would be minimal. An inverted duty structure arises where the rate of
tax on inputs exceeds the rate of tax on output supplies as a result of
which the unutilized ITC may get accumulated. The jurisprudential
material which has been relied upon by the assesses portrays an ideal
state of GST legislation. In the well-known treatise on VAT, Alan Schenk
and Oliver Oldman27 explained the principled basis in VAT/GST legislation       G
for the grant of refund of excess input tax credit. According to the authors:

A           “II. Treatment of Excess Input Credits –Carry Forward, Offset,
            or Refund:
            As was discussed earlier and will be discussed in detail in Chapter
            7, most countries define the jurisdictional reach of their VATs under
            the destination principle. Applying the destination principle,
B           exports are free of tax (zero rated). As a result, exporters
            commonly report excess input VAT in their periodic VAT
            returns. In addition, even registered persons making sales
            taxable at a positive rate may experience occasional excess
            input VATs, such as when they make capital purchases
            generating substantial input credits or when they increase
C           their inventory as part of an expansion of their businesses.
            There is an implicit assumption in VAT systems that registered
            persons will recover input VAT used in making taxable sales so
            that the input VAT does not enter into the pricing structure for
            those sales. To accomplish that goal, a normative or well-structured
D           VAT must grant registered persons the right to recover excess
            input VATs within a reasonable period of time after incurring the
            input t(a)x (sic). …
            In the EU, the Sixth Directive provides that if there are excess
            input tax deductions, “Member States may either make a refund
E           or carry the excess forward to the following period according to
            conditions which they shall determine. For Member States, excess
            credits must be refunded after being carried forward six months.
            However, Member States may refuse to refund or carry forward
            if the amount of the excess is insignificant…”
F                                                         (emphasis supplied)
             60. The jurisprudential basis furnishes a depiction of an ideal state
      of existence of GST legislation within the purview of a modern economy,
      as a destination-based tax. But there can be no gain saying the fact that
      fiscal legislation around the world, India being no exception, makes
G     complex balances founded upon socio-economic complexities and
      diversities which permeate each society. The form which a GST
      legislation in a unitary State may take will vary considerably from its
      avatar in a nation such as India where a dual system of GST law operates
      within the context of a federal structure. The ideal of a GST framework
      which Article 279A(6) embodies has to be progressively realized. The
H
    UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                              245

doctrines which have been emphasized by Counsel during the course of            A
the arguments furnish the underlying rationale for the enactment of the
law but cannot furnish either a valid basis for judicial review of the
legislation or make out a ground for invalidating a validly enacted law
unless it infringes constitutional parameters. While adopting the
constitutional framework of a GST regime, Parliament in the exercise of
                                                                                B
its constituent power has had to make and draw balances to accommodate
the interests of the States. Taxes on alcohol for human consumption and
stamp duties provide a significant part of the revenues of the States.
Complex balances have had to be drawn so as to accommodate the
concerns of the states before bringing them within the umbrella of GST.
These aspects must be borne in mind while assessing the jurisprudential         C
vision and the economic rationale for GST legislation. But abstract doctrine
cannot be a ground for the Court to undertake the task of redrawing the
text or context of a statutory provision. This is clearly an area of law
where judicial interpretation cannot be ahead of policy making. Fiscal
policy ought not be dictated through the judgments of the High Courts or
                                                                                D
this Court. For it is not the function of the Court in the fiscal arena to
compel Parliament to go further and to do more by, for instance, expanding
the coverage of the legislation (to liquor, stamp duty and petroleum) or to
bring in uniformity of rates. This would constitute an impermissible judicial
encroachment on legislative power. Likewise, when the first proviso to
Section 54(3) has provided for a restriction on the entitlement to refund       E
it would be impermissible for the Court to redraw the boundaries or to
expand the provision for refund beyond what the legislature has provided.
If the legislature has intended that the equivalence between goods and
services should be progressively realized and that for the purpose of
determining whether refund should be provided, a restriction of the kind
                                                                                F
which has been imposed in clause (ii) of the proviso should be enacted,
it lies within the realm of policy.
      61. The submission which has been urged on behalf of the
assessees is that registered persons constitute a class within the meaning
of sub-Section (3) of Section 54 and each of them is entitled to claim a
refund of unutilized ITC whether its origin lies in input goods or input        G
services. In other words, it has been urged that Section 54(3) constitutes
one homogenous class of registered persons who have unutilized ITC.
The fallacy of the argument is in the hypothesis that unutilized ITC cannot
be unbundled for the purpose of fiscal legislation. Accumulated ITC
may result due to a variety of circumstances, some of which may while           H
246             SUPREME COURT REPORTS                           [2021] 15 S.C.R.


A     others may not lie within the volition of a registered person. We have
      referred to some of these factors earlier, including
             (i) High discount pricing;
             (ii) Predatory pricing;
B            (iii) Shut down of business or industry;
             (iv) Business loss;
             (v) Economic compulsion to sell at below value prices; and
             (vi) Stoppage of work.
C
              62. These examples are indicators that the class, comprising of
      registered persons with unutilized ITC, covers a bundle of species as
      opposed to one unique or homogenous specie. Once we recognize this,
      it is necessary to allow the legislature the latitude to distinguish between
      credits arising out of the input goods stream and input service stream.
D     GST legislation in India is the product of hard constitutional and legislative
      work which stretched over several decades. Our fiscal regime is yet to
      arrive at an ideological position of one bundle for goods and services
      based on a single rate structure. Broadly speaking, goods and services
      are taxed at 5 per cent, 12 per cent, 18 per cent and 40 per cent. As on
      date, there is an absence of uniformity in rates and it is the multiplicity of
E
      rates which has given rise to an inverted duty structure. Registered
      persons with unutilized ITC may conceivably form one class but it is not
      possible to ignore that this class consists of species of different hues.
      Given these intrinsic complexities, the legislature has to draw the balance
      when it decides upon granting a refund of accumulated ITC which has
F     remained unutilized. In doing so, Parliament while enacting sub-Section
      (3) of Section 54 has stipulated that no refund of unutilized ITC shall be
      allowed other than in the two specific situations envisaged in clauses (i)
      and (ii) of the first proviso. Whereas clause (i) has dealt with zero rated
      supplies made without the payment of tax, clause (ii), which governs
      domestic supplies, has envisaged a more restricted ambit where the credit
G
      has accumulated on account of the rate of tax on inputs being higher
      than the rate of tax on output supplies. While the CGST Act defines the
      expression ‘input’ in Section 2(59) by bracketing it with goods other than
      capital goods, it is true that the plural expression ‘inputs’ has not been
      specifically defined. But there is no reason why the ordinary principle of

         [DR DHANANJAYA Y CHANDRACHUD, J.]

construing the plural in the same plane as the singular should not be                  A
applied. To construe ‘inputs’ so as to include both input goods and input
services would do violence to the provisions of Section 54(3) and would
run contrary to the terms of Explanation-I which have been noted earlier.
Consequently, it is not open to the Court to accept the argument of the
assessee that in the process of construing Section 54(3) contextually,
                                                                                       B
the Court should broaden the expression ‘inputs’ to cover both goods
and services.
       F.4 Construing the proviso
       63. Provisos in a statute have multi-faceted personalities. As
interpretational principles governing statutes have evolved, certain basic             C
ideas have been recognized, while heeding to the text and context. Justice
GP Singh, in his seminal text, Principles of Statutory Interpretation28
formulates the governing principles of interpretation which have been
adopted by courts while construing a statutory proviso. The first rule of
interpretation is that:
                                                                                       D
       “The normal function of a proviso is to except something
       out of the enactment or to qualify something enacted therein
       which but for the proviso would be within the purview of
       the enactment. As stated by LUSH, J.: “When one finds a proviso
       to a section the natural presumption is that, but for the proviso, the
                                                                                       E
       enacting part of the section would have included the subject- matter
       of the proviso. In the words of LORD MACMILLAN: “The proper
       function of a proviso is to except and to deal with a case which
       would otherwise fall within the general language of the main
       enactment and its effect is confined to that case.” The proviso
       may, as LORD MACNAGHTEN laid down, be “a qualification                          F
       of the preceeding enactment which is expressed in terms too
       general to be quite accurate”. The general rule has been stated by
       HIDAYATULLAH, J., in the following words: “As a general rule,
       a proviso is added to an enactment to qualify or create an exception
       to what is in the enactment, and ordinarily, a proviso is not
                                                                                       G
       interpreted as stating a general rule”. And in the words of KAPUR,
       J.: “The proper function of a proviso is that it qualifies the generality
       of the main enactment by providing an exception and taking out as

              proviso would fall within the main enactment.” 29
                                                            (emphasis supplied)
             64. But then these principles are subject to other principles of
      statutory interpretation which may supplement or even substitute the
B     above formula. These other rules which have been categorized by Justice
      GP Singh are summarized as follows:
              (i) A proviso is not construed as excluding or adding something
                  by implication:

C                 “Except as to cases dealt with by it, a proviso has no
                  repercussion on the interpretation of the enacting portion of the
                  section so as to exclude something by implication which is
                  embraced by clear words in the enactment.”30
              (ii) A proviso is construed in relation to the subject matter of the
D                  statutory provision to which it is appended:
                  “The language of a proviso even if general is normally to be
                  construed in relation to the subject-matter covered by the section
                  to which the proviso is appended. In other words normally a
                  proviso does not travel beyond the provision to which it is a
                  proviso. “It is a cardinal rule of interpretation”, observed
E
                  BHAGWATI, J., “that a proviso to a particular provision of a
                  statute only embraces the field which is covered by the main
                  provision. It carves out an exception to the main provision to
                  which it has been enacted as a proviso and to no other.” 31
              (iii) Where the substantive provision of a statute lacks clarity, a
F
                    proviso may shed light on its true meaning:
                  “If the enacting portion of a section is not clear, a proviso
                  appended to it may give an indication as its true meaning. As
                  stated by LORD HERSCHELL: “ Of course a proviso may be
                  used to guide you in the selection of one or other of two possible
G
                  constructions of the words to be found in the enactment, and
                  show when there is doubt about its scope, when it may

          reasonably admit of doubt as to having this scope or that, which       A
          is the proper view to take of it.”32
       (iv) An effort should be made while construing a statute to give
            meaning both to the main enactment and its proviso bearing
            in mind that sometimes a proviso is inserted as a matter of
            abundant caution:                                                    B
          “The general rule in construing an enactment containing a
          proviso is to construe them together without making either of
          them redundant or otiose. Even if the enacting part is clear
          effort is to be made to give some meaning to the proviso and to
          justify its necessity. But a clause or a section worded as a           C
          proviso, may not be a true proviso and may have been placed
          by way of abundant caution.”33
       (v) While ordinarily, it would be unusual to interpret the proviso
           as an independent enacting clause, as distinct from its main
           enactment, this is true only of a real proviso and the draftsperson   D
           of the statute may have intended for the proviso to be, in
           substance, a fresh enactment:
          “To read a proviso as providing something by way of an
          addendum or as dealing with a subject not covered by the main
          enactment or as stating a general rule as distinguished from an        E
          exception or qualification is ordinarily foreign to the proper
          function of a proviso. However, this is only true of a real proviso.
          The insertion of a proviso by the draftsman has not always
          strictly adhered to its legitimate use and at times a section worded
          as a proviso may wholly or partly be in substance a fresh
          enactment adding to and not merely excepting something out             F
          of or qualifying what goes before.”34
      65. Perhaps the most comprehensive and oft-cited precedent
governing the interpretation of a proviso is the decision of this Court in S
Sundaram Pillai v. V R Pattabiraman35. Justice S Murtaza Fazal Ali
speaking for a three judge Bench of this Court held:                             G

250             SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A           “43. …To sum up, a proviso may serve four different purposes:
            (1) qualifying or excepting certain provisions from the main
            enactment:
            (2) it may entirely change the very concept of the intendment of
            the enactment by insisting on certain mandatory conditions to be
B           fulfilled in order to make the enactment workable:
            (3) it may be so embedded in the Act itself as to become an integral
            part of the enactment and thus acquire the tenor and colour of the
            substantive enactment itself; and
            (4) it may be used merely to act as an optional addenda to the
C           enactment with the sole object of explaining the real intendment
            of the statutory provision.”
            66. While enunciating the above principles, S Sundaram Pillai
      (supra) took note of the decision in Hiralal Rattanlal v. State of UP36
      where Justice KS Hegde, speaking for a four judge Bench of this Court
      observed that while ordinarily, a proviso is in the nature of an exception,
D
      the precedents indicate that sometimes a proviso is in the nature of a
      separate provision, with a life of its own. The Court held:
            “22… Ordinarily a proviso to a section is intended to take out a
            part of the main section for special treatment. It is not expected to
            enlarge the scope of the main section. But cases have arisen in
E           which this Court has held that despite the fact that a provision is
            called a proviso, it is really a separate provision and the so-called
            proviso has substantially altered the main section.
            In CIT v. Bipinchandra Maganlal & Co. Ltd., Bombay [AIR
            1961 SC 1040 : (1961) 2 SCR 493 : (1961) 41 ITR 290] this Court
F           held that by the fiction in Section 10(2)(vii) second proviso read
            with Section 2(6-C) of the Indian Income Tax Act, 1922 what is
            really not income is, for the purpose of computation of assessable
            income, made taxable income.”
            Besides the decision in CIT v. Bipinchandra Maganlal37, the
      Court in Hiralal Rattanlal (supra) adverted to the earlier decisions in
G
      State of Rajasthan v. Leela Jain 38 and Bihar Cooperative

       67. In their effort to persuade this Court to accept the submission              A
that the first proviso to Section 54(3) is in the nature of an eligibility
condition as distinct from a restriction on the substantive part (contained
in the opening words) of the provision, Counsel appearing on behalf of
the assessees have sought to buttress their submissions with the following
facets:
                                                                                        B
       (i)     Clause (ii) of the first proviso refers to “rate of tax” as
               distinct from the quantum of tax;
       (ii)    The expression “in cases other than where…” adverts to
               situations or circumstances;
       (iii)   The expression “on account of” would mean “due to”;                      C

       (iv)    The use of the expression ‘inputs’ (the singular being defined
               in Section 2(59) but not the plural) and the corresponding
               use of the expression “output supplies” (which is not defined,
               though “outward supply” is defined in Section 2(83));
                                                                                        D
       (v)     Section 54(8) and Section 49(6) provide that the balance in
               the electronic credit ledger is to be refunded and makes no
               distinction between a credit relatable to goods or to services;
       (vi)    The expression “on account of” has been used in Section
               22(3) and Section 18(3) and is distinct from the use of the
                                                                                        E
               expression “to the extent of” in Section 23(1)(b) and the
               proviso to Section 12(2). “To the extent of” is a limiting
               expression and has a distinct connotation from “on account
               of”;
       (vii)   The Ministry of Finance has issued a circular dated 31

A              specified in rule 89(5) of the CGST Rules. The matter has
               been examined and the following issues are clarified:
      a)       Refund of unutilized ITC in case of inverted tax structure,
               as provided in section 54(3) of the CGST Act, is available
               where ITC remains unutilized even after setting off of
B              available ITC for the payment of output tax liability. Where
               there are multiple inputs attracting different rates of tax, in
               the formula provided in rule 89(5) of the CGST Rules, the
               term “Net ITC covers the ITC availed on all inputs in the
               relevant period, irrespective of their rate of tax.
C     b)       The calculation of refund of accumulated ITC on account
               of inverted tax structure, in cases where several inputs are
               used in supplying the final product/output, can be clearly
               understood with help of the following example:
      i.         Suppose a manufacturing process involves the use of an
D                input A (attracting 5 per cent GST) and input B (attracting
                 18 per cent GST) to manufacture output Y (attracting 12
                 per cent GST).
      ii.        The refund of accumulated ITC in the situation at (i) above,
                 will be available under section 54(3) of the CGST Act
E                read with rule 89(5) of the CGST Rules, which prescribes
                 the formula for the maximum refund amount permissible
                 in such situations.
      iii.       Further assume that the claimant supplies the output Y
                 having value of Rs. 3,000/- during the relevant period for
F                which the refund is being claimed. Therefore, the turnover
                 of inverted rated supply of goods and services will be Rs.
                 3,000/-. Since the claimant has no other outward supplies,
                 his adjusted total turnover will also be Rs. 3,000/-.
      iv.        If we assume that Input A, having value of Rs. 500/- and
                 Input B, having value of Rs. 2,000/-, have been purchased
G
                 in the relevant period for the manufacture of Y, then Net
                 ITC shall be equal to Rs. 385/- (Rs. 25/- and Rs. 360/- on
                 Input A and Input B respectively).
      v.         Therefore, multiplying Net ITC by the ratio of turnover of
                 inverted rated supply of goods and services to the adjusted
H                total turnover will give the figure of Rs. 385/-.

        [DR DHANANJAYA Y CHANDRACHUD, J.]

       vi.      From this, if we deduct the tax payable on such inverted         A
                rated supply of goods or services, which is Rs. 360/-, we
                get the maximum refund amount, as per rule 89(5) of the
                CGST Rules which is Rs. 25/-.”
       68. Para 4(b) of the Circular thereafter proceeds to give certain
illustrations. The above circular, it is urged, would demonstrate that the       B
phrase “on account of” in the proviso is interpreted by the State qua
goods as a threshold condition. Hence even if one input in the basket of
inputs of a manufacturer results in an inverted duty structure, the whole
of the accumulated ITC can be availed of. On the other hand, for services
the same phrase is interpreted so as to mean ‘to the extent of’. The
expression “on account of” as understood for goods by the above circular         C
must apply for services as well, meaning thereby that it is a threshold
condition alone.
        69. The above submissions demonstrate the scholarship which
has been brought to bear upon the controversy by Counsel appearing on
behalf of the assessees. The above aspects of the statutory provision –          D
Section 54(3) - must be juxtaposed together with all the features of the
statutory provision including Explanation- I which have been adverted to
earlier. The analysis earlier indicates why on a reading of the provision
as a whole, clauses (i) and (ii) of the first proviso are restrictions and not
mere conditions of eligibility. It is not possible for the Court to restrict     E
the ambit of clause (ii) of the proviso, based on a circular which has
been issued by the Ministry of Finance on 31 December 2018. In
substance, the argument boils down to an effort to lead this Court to hold
that in spite of the language which has been used in clause (ii) of the first
proviso, (where the credit is accumulated on account of rate of tax on
inputs being higher than the rate of tax on output supplies), input services     F
must be read into the term “inputs”. The assessees argue that the
Departmental understanding, as reflected in the circular, should be the
basis of interpreting a statutory provision. Such an exercise would be
impermissible, when its effect is to expand the area of refund
contemplated by the first proviso to cover input services in addition to         G
input goods despite statutory language to the contrary. Sub-Section (3)
of Section 54 begins, in its main part, with the stipulation that a registered
person may claim refund of any ‘unutilised ITC at the end of any tax
period’. Whether we construe the first proviso as an exception or in the
nature of a fresh enactment, the clear intent of Parliament was to confine
                                                                                 H

A     the grant of refund to the two categories spelt out in clauses (i) and (ii)
      of the first proviso. That clauses (i) and (ii) are the only two situations in
      which a refund can be granted is evident from the opening words of the
      first proviso which stipulates that “no refund of unutilised input tax
      credit shall be allowed in cases other than”. What follows is clauses
      (i) and (ii). The intent of Parliament is evident by the use of a double –
B
      negative format by employing the expression “no refund” as well as the
      expression “in cases other than”. In other words, a refund is contemplated
      in the situations provided in clauses (i) and (ii) and no other. To put it
      differently, the first proviso can be recast, without altering its meaning to
      read that a refund of unutilised ITC shall be allowed only in the cases
C     governed by clauses (i) and (ii). Clause (i) deals with zero rated supplies
      without payment of tax. Explanation-1 to Section 54 clarifies that the
      expression ‘refund’ includes refund of tax paid on zero rated supplies on
      goods or services or both, or on inputs or input services used in making
      such zero-rated supplies. On the other hand, in the case of deemed
      exports, Explanation-1 refers to a refund of tax on the supply of goods.
D
      Likewise in regard to domestic supplies, governed by clause (ii) of the
      first proviso, the expression ‘refund’ means refund of unutilised ITC as
      provided under sub-Section (3). With the clear language which has been
      adopted by Parliament while enacting the provisions of Section 54(3),
      the acceptance of the submission which has been urged on behalf of the
E     assessee would involve a judicial re-writing of the provision which is
      impermissible in law. Clause (ii) of the proviso, when it refers to “on
      account of” clearly intends the meaning which can ordinarily be said to
      imply ‘because of or due to’. When proviso (ii) refers to “rate of tax”, it
      indicates a clear intent that a refund would be allowed where and only if
      the inverted duty structure has arisen due to the rate of tax on input
F
      being higher than the rate of tax on output supplies. Reading the expression
      ‘input’ to cover input goods and input services would lead to recognising
      an entitlement to refund, beyond what was contemplated by Parliament.
              70. We must be cognizant of the fact that no constitutional right is
      being asserted to claim a refund, as there cannot be. Refund is a matter
G     of a statutory prescription. Parliament was within its legislative authority
      in determining whether refunds should be allowed of unutilised ITC
      tracing its origin both to input goods and input services or, as it has
      legislated, input goods alone. By its clear stipulation that a refund would
      be admissible only where the unutilised ITC has accumulated on account
H     of the rate of tax on inputs being higher than the rate of tax on output

supplies, Parliament has confined the refund in the manner which we              A
have described above. While recognising an entitlement to refund, it is
open to the legislature to define the circumstances in which a refund can
be claimed. The proviso to Section 54(3) is not a condition of eligibility
(as the assessees’ Counsel submitted) but a restriction which must govern
the grant of refund under Section 54(3). We therefore, accept the
                                                                                 B
submission which has been urged by Mr N Venkataraman, learned ASG.
         F.5 Constitutional validity: The ultra vires doctrine
       71. The submission which has been urged on behalf of the
assessees is that if Section 54(3) is construed to confine a refund of
unutilised ITC only to the extent that the accumulation arises on account        C
of the rate of tax on inputs (meaning input goods) exceeding the rate of
tax on outward supplies, the principles underlying Article 14 of the
Constitution would be attracted and the statutory provision would suffer
from the vice of arbitrariness. The submission is that this has become an
incident of a class legislation: the class consists of registered persons
having unutilised ITC. The class comprises of the following species (i)          D
domestic suppliers; and (ii) exporters. The sub-species are (i) input goods;
and (ii) input services. Opposing this submission, the learned ASG’s
submission is that this is a valid classification, denying one of the species
namely input services the benefit of refund.
       72. The principle which Counsel for the assesses espouse is sought        E
to be buttressed by relying upon the decision in State of Jammu &
Kashmir v. Triloki Nath Khosa41 and in Re The Special Courts
Bill, 197842. The principles which are gleaned by Counsel from the
above decisions, in their application to the present case, are that:
         (i)    Once the ITC comes within the fold of the electronic credit      F
                ledger and is comprised into a homogenous credit, a ‘micro
                distinction’ cannot be carried out; and
         (ii)   A similarity of features between species comprised in the
                class is sufficient: in the case of goods as well as services,
                the taxable event is the value addition tax and the              G
                administrative machinery treats goods as well as services
                similarly. The mere fact of goods being tangible is a matter
                of no consequence.

A            73. Equality, it has been stressed in the above submission, cannot
      be cabined, cribbed and confined. Differentiating between goods and
      services, it has been urged, is not permissible and does not have a
      reasonable nexus to the object sought to be achieved. There is an evident
      difference in the rates at which goods and services are taxed but,
      according to the submission, this is not a provision for revenue harvesting.
B
      Finally, on this limb of submission, it has been urged that the wide latitude
      which is available with the legislature in the case of fiscal legislation is
      only where a revenue harvesting measure is involved. The twin test of
      reasonableness and the nexus with the object sought to be achieved
      must be demonstrated. The nexus (a) must be based on the object of the
C     legislation alone; and (b) indicate a discernible principle which emanates
      from the classification. With the clarification on inputs by the Ministry of
      Finance, it is urged that no discernible principle emerges.
             74. Counsel for the assesses also argued that before the High
      Courts of Gujarat and Madras, the Union Government did not urge that
D     outflow of finance was the reason to exclude refunds on input services
      and it is not open to the Court to conjure up a reason. In support of the
      above submissions on constitutional validity, which have been urged by
      Mr Sujit Ghosh, learned Counsel, Mr Arvind Datar, learned Senior
      Counsel has urged that it would be paradoxical to posit on the one hand
      that goods and services are pari materia for the purpose of levy, collection
E     and penalty but, that a distinction will be made between them for the
      purpose of refund.
              75. As a matter of first principle, it is not possible to accept the
      premise that the guiding principles which impart a measure of flexibility
      to the legislature in designing appropriate classifications for the purpose
F     of a fiscal regime should be confined only to the revenue harvesting
      measures of a statute. The precedents of this Court provide abundant
      justification for the fundamental principle that a discriminatory provision
      under tax legislation is not per se invalid. A cause of invalidity arises
      where equals are treated as unequally and unequals are treated as equals.
G     Both under the Constitution and the CGST Act, goods and services and
      input goods and input services are not treated as one and the same and
      they are distinct species.
            76. Parliament engrafted a provision for refund Section 54(3). In
      enacting such a provision, Parliament is entitled to make policy choices
H     and adopt appropriate classifications, given the latitude which our

           [DR DHANANJAYA Y CHANDRACHUD, J.]

constitutional jurisprudence allows it in matters involving tax legislation        A
and to provide for exemptions, concessions and benefits on terms, as it
considers appropriate. The consistent line of precedent of this Court
emphasises certain basic precepts which govern both judicial review
and judicial interpretation of tax legislation. These precepts are:
         (i)    Selecting the objects to be taxed, determining the quantum         B
                of tax, legislating for the conditions for the levy and the
                socio-economic goals which a tax must achieve are matters
                of legislative policy. Chief Justice M. Hidayatullah, speaking
                for the Constitution Bench in Assistant Commissioner
                of Urban Land Tax v. Buckingham and Carnatic Co.
                Ltd.43 held:                                                       C

                “10…The objects to be taxed, the quantum of tax to be
                levied, the conditions subject to which it is levied and the
                social and economic policies which a tax is designed to
                subserve are all matters of political character and these
                matters have been entrusted to the Legislature and not to          D
                the Courts. In applying the test of reasonableness it is also
                essential to notice that the power of taxation is generally
                regarded as an essential attribute of sovereignty and
                constitutional provisions relating to the power of taxation
                are regarded not as grant of power but as limitation upon          E
                the power which would otherwise be practically without
                limit.
         (ii)   The same principle has been reiterated in Federation of
                Hotel & Restaurant Association of India v. Union of
                India44, where Justice MN Venkatachaliah (as the learned           F
                Chief Justice then was), speaking for the Constitution Bench
                held:
                “46. It is now well settled that though taxing laws are not
                outside Article 14, however, having regard to the wide variety
                of diverse economic criteria that go into the formulation of       G
                a fiscal policy legislature enjoys a wide latitude in the matter
                of selection of persons, subject-matter, events, etc., for
                taxation. The tests of the vice of discrimination in a taxing

A             law are, accordingly, less rigorous. In examining the
              allegations of a hostile, discriminatory treatment what is
              looked into is not its phraseology, but the real effect of its
              provisions. A legislature does not, as an old saying goes,
              have to tax everything in order to be able to tax something.
              If there is equality and uniformity within each group, the
B
              law would not be discriminatory. Decisions of this Court on
              the matter have permitted the legislatures to exercise an
              extremely wide discretion in classifying items for tax
              purposes, so long as it refrains from clear and hostile
              discrimination against particular persons or classes.
C             47. But, with all this latitude certain irreducible desiderata
              of equality shall govern classifications for differential
              treatment in taxation laws as well. The classification must
              be rational and based on some qualities and characteristics
              which are to be found in all the persons grouped together
D             and absent in the others left out of the class. But this alone
              is not sufficient. Differentia must have a rational nexus with
              the object sought to be achieved by the law. The State, in
              the exercise of its governmental power, has, of necessity, to
              make laws operating differently in relation to different groups
              or classes of persons to attain certain ends and must,
E             therefore, possess the power to distinguish and classify
              persons or things. It is also recognised that no precise or set
              formulae or doctrinaire tests or precise scientific principles
              of exclusion or inclusion are to be applied. The test could
              only be one of palpable arbitrariness applied in the context
F             of the felt needs of the times and societal exigencies informed
              by experience.”
      (iii)   In matters of classification, involving fiscal legislation, the
              legislature is permitted a larger discretion so long as there
              is no transgression of the fundamental principle underlying
G             the doctrine of classification. In Hiralal Rattanlal (supra),
              Justice KS Hegde, speaking for a four judge Bench
              observed:
              “20. It must be noticed that generally speaking the primary
              purpose of the levy of all taxes is to raise funds for public
H             good. Which person should be taxed, what transaction should
       UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                               259
           [DR DHANANJAYA Y CHANDRACHUD, J.]

                be taxed or what goods should be taxed, depends upon                A
                social, economic and administrative considerations. In a
                democratic set up it is for the Legislature to decide what
                economic or social policy it should pursue or what
                administrative considerations it should bear in mind. The
                classification between the processed or split pulses and
                                                                                    B
                unprocessed or unsplit pulses is a reasonable classification.
                It is based on the use to which those goods can be put.
                Hence, in our opinion, the impugned classification is not
                violative of Article 14.”
         (iv)   More recently in Union of India v. NITDIP Textile
                Processors Private Limited 45 , a two judge Bench                   C
                observed:
                “67. It has been laid down in a large number of decisions of
                this Court that a taxation statute, for the reasons of functional
                expediency and even otherwise, can pick and choose to tax
                some. A power to classify being extremely broad and based           D
                on diverse considerations of executive pragmatism, the
                judicature cannot rush in where even the legislature warily
                treads. All these operational restraints on judicial power must
                weigh more emphatically where the subject is taxation.
                Discrimination resulting from fortuitous circumstances              E
                arising out of particular situations, in which some of the tax-
                payers find themselves, is not hit by Article 14 if the
                legislation, as such, is of general application and does not
                single them out for harsh treatment. Advantages or
                disadvantages to individual assessees are accidental and
                inevitable and are inherent in every taxing statute as it has       F
                to draw a line somewhere and some cases necessarily fall
                on the other side of the line.”
      77. The principles governing a benefit, by way of a refund of tax
paid, may well be construed on an analogous frame with an exemption
from the payment of tax or a reduction in liability (Assistant                      G
Commissioner of Commercial Tax (Asst.) v. Dharmendra Trading
Company46).

A            78. In Elel Hotels and Investments Limited and Others v.
      Union of India47, Justice MN Venkatachaliah (as the learned Chief
      Justice then was) held that:
               “20…It is now well settled that a very wide latitude is available to
               the legislature in the matter of classification of objects, persons
B              and things for purposes of taxation. It must need to be so, having
               regard to the complexities involved in the formulation of a taxation
               policy. Taxation is not now a mere source of raising money to
               defray expenses of Government. It is a recognised fiscal tool to
               achieve fiscal and social objectives. The differentia of classification
               presupposes and proceeds on the premise that it distinguishes and
C              keeps apart as a distinct class hotels with higher economic status
               reflected in one of the indicia of such economic superiority. The
               presumption of constitutionality has not been dislodged by the
               petitioners by demonstrating how even hotels, not brought into the
               class, have also equal or higher chargeable receipts and how the
D              assumption of economic superiority of hotels to which the Act is
               applied is erroneous or irrelevant.”
             79. In Spences Hotel Pvt Ltd. v. State of West Bengal48, a
      two judge Bench, speaking through Justice KN Saikia, revisited the
      precedents of this Court governing the principles of classification in tax
E     legislation and held:
               “24…The history of taxation is one of evolution as is the case in
               all human affairs. Its progress is one of constant growth and
               development in keeping with the advancing economic and social
               conditions; and the fiscal intelligence of the State has been
F              advancing concomitantly, subjecting by new means and methods
               hitherto untaxed property, income, service and provisions to
               taxation. With the change of scientific, commercial and economic
               conditions and ways of life new species of property, both tangible
               and intangible gaining enormous values have come into existence
               and new means of reaching and subjecting the same to contribute
G              towards public finance are being developed, perfected and put
               into practical operation by the legislatures and courts of this country,
               of course within constitutional limitations.”

        80. The Court held that the principle of equality does not preclude      A
the classification of property, trade, profession and events for taxation –
subjecting one kind to one rate of taxation and another to a different
rate. The State may exempt certain classes of property from any taxation
at all and impose different specific taxes upon different species which it
seeks to regulate. The Court held:
                                                                                 B
       “27. ”Perfect equality in taxation has been said time and again, to
       be impossible and unattainable. Approximation to it is all that can
       be had. Under any system of taxation, however, wisely and
       carefully framed, a disproportionate share of the public burdens
       would be thrown on certain kinds of property, because they are
       visible and tangible, while others are of a nature to elude vigilance.    C
       It is only where statutes are passed which impose taxes on false
       and unjust principle, or operate to produce gross inequality, so that
       they cannot be deemed in any just sense proportional in their effect
       on those who are to bear the public charges that courts can interpose
       and arrest the course of legislation by declaring such enactments         D
       void.” “Perfectly equal taxation”, it has been said, “will remain an
       unattainable good as long as laws and government and man are
       imperfect.” ‘Perfect uniformity and perfect equality of taxation’,
       in all the aspects in which the human mind can view it, is a baseless
       dream.”
                                                                                 E
       81. Parliament while enacting the provisions of Section 54(3),
legislated within the fold of the GST regime to prescribe a refund. While
doing so, it has confined the grant of refund in terms of the first proviso
to Section 54(3) to the two categories which are governed by clauses (i)
and (ii). A claim to refund is governed by statute. There is no constitutional
entitlement to seek a refund. Parliament has in clause (i) of the first          F
proviso allowed a refund of the unutilized ITC in the case of zero-rated
supplies made without payment of tax. Under clause (ii) of the first
proviso, Parliament has envisaged a refund of unutilized ITC, where the
credit has accumulated on account of the rate of tax on inputs being
higher than the rate of tax on output supplies. When there is neither a          G
constitutional guarantee nor a statutory entitlement to refund, the
submission that goods and services must necessarily be treated at par
on a matter of a refund of unutilized ITC cannot be accepted. Such an
interpretation, if carried to its logical conclusion would involve unforeseen
consequences, circumscribing the legislative discretion of Parliament to
                                                                                 H

A     fashion the rate of tax, concessions and exemptions. If the judiciary
      were to do so, it would run the risk of encroaching upon legislative choices,
      and on policy decisions which are the prerogative of the executive. Many
      of the considerations which underlie these choices are based on complex
      balances drawn between political, economic and social needs and
      aspirations and are a result of careful analysis of the data and information
B
      regarding the levy of taxes and their collection. That is precisely the
      reason why courts are averse to entering the area of policy matters on
      fiscal issues. We are therefore unable to accept the challenge to the
      constitutional validity of Section 54(3).
            G Rule 89(5)
C
              82. Rule 89(5) of the CGST Rules provides for the computation
      of the refund of ITC on account of an inverted duty structure. The rule,
      as it was originally enacted, provided for a refund of ITC paid both on
      input goods and input services. Rules 89(5) was amended on 18 April
      2018 with prospective effect. On 13 June 2018, Rule 89(5) as amended
D     was substituted with retrospective effect from 1 July 2017. The effect
      of this amendment is that refund of unutilized ITC can only be availed on
      input goods.
             83. Section 164 of the CGST Act empowers the ‘government’
      (the expression ‘government’ being defined in Section 2(53) to mean the
E     Central Government) to make rules for carrying out the provisions of
      the Act on the recommendations of the GST Council. Sub-Section (3) of
      Section 164 stipulates that that power to make rules shall include the
      power to make rules with retrospective effect not earlier than the date
      on which the provisions of the Act came into force. As a result of the
F     amendment of Rule 89(5), the formula which has been specified for the
      refund of ITC is as follows:
            “Maximum Refund Amount = {(Turnover of inverted rated supply
            of goods and services) x Net ITC ÷ Adjusted Total Turnover} –
            tax payable on such inverted rated supply of goods and services.
G           Explanation- For the purposes of this sub-rule, the expressions-
            (a)     Net ITC shall mean input tax credit availed on inputs during
                    the relevant period other than the input tax credit availed
                    for which refund is claimed under sub-rules (4A) or (4B) or
                    both; and
H
    UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                             263
        [DR DHANANJAYA Y CHANDRACHUD, J.]

      (b)    Adjusted Total turnover shall have the same meaning as            A
             assigned to them in sub-rule (4).”
      G.1 The validity of Rule 89(5) of CGST Rules in exercise of
the rule-making power under Section 164 of the CGST Act
       84. A preliminary submission which has been urged by
Mr V Sridharan, learned Senior Counsel is that the rule-making power           B
under Section 164 of the CGST Act can only be used if specific authority
for making the rule is granted by the particular section of the CGST Act.
Elaborating on this submission, Mr V Sridharan has submitted that under
the CGST Act, various sections expressly employ the word “prescribed”
to indicate that rules may be formulated by way of delegated legislation       C
for that particular section. As an instance, Mr Sridharan points out that
Section 9 provides that the manner in which tax is to be collected may
be ‘prescribed’; Section 16(1) provides for conditions and restrictions
for availing ITC which may be ‘prescribed’ and Section 31(2) provides
that the time within which a person supplying a taxable service must
issue an invoice may be ‘prescribed’. These are examples where the             D
statute has expressly contemplated that rules would have to be framed
to give effect to a specific provision. It is the submission of Mr Sridharan
that in the absence of such words in the text of the legislation, the
government cannot exercise its authority under Section 164 of the CGST
Act to frame rules for other sections. Thus, since Section 54(3) does not      E
provide any words which indicate that specific authority has been granted
for framing rules, Rule 89(5) is (according to the submission) invalid.
       85. We are unable to accept the above submission as it proceeds
on a misconception. Under Section 164(1), confers an express power
on the Central Government to make rules for carrying out the provisions        F
of the CGST Act on the recommendations of the GST Council. It may
be true that in certain specific statutory provisions, the Act recognizes,
by using the expression ‘prescribes’, that rules may be framed for that
purpose. But the converse cannot be assumed inferentially, by presuming
that in other areas, recourse to the rule making power cannot be taken.
By its very nature, a statutory provision may not visualize every              G
eventuality which may arise in implementing the provisions of the Act.
Hence it is open to the rule making authority to frame rules, so long as
they are consistent with the provisions of the parent enactment. The
rules may interstitially fill-up gaps which are unattended in the main
legislation or introduce provisions for implementing the legislation. So       H
264             SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A     long as the authority which frames the rules has not transgressed a
      provision of the statute, it cannot be deprived of its authority to exercise
      the rule making power. The wide powers given under Section 164 of the
      CGST Act are only limited by the provisions of the Act itself, in
      furtherance of which a rule maybe framed. It is for this reason that the
      powers under Section 164 are not restricted to only those sections which
B
      grant specific authority to frame rules. If such a construction, as Mr
      Sridharan has hypothesised, were to be acceptable, it would render the
      provisions of Section 164 otiose. Thus, we find that the absence of the
      words “as may be prescribed” in Section 54(3) does not deprive the rule
      making authority to make rules for carrying out the provisions of the
C     Act.
          G.2 The vires of Rule 89(5) vis-à-vis Section 54(3) of the
      CGST Act
             86. The next submission which has been urged by Mr V Sridharan,
      learned Senior Counsel is that Rule 89(5) is not in line with Section
D     54(3). The rule, as retrospectively amended, is asserted to be ultra vires
      Section 54(3) in as much as it restricts the computation of refund by
      taking into account only the credit availed on input goods. Moreover,
      under Section 54(1), the CGST Rules can provide only the form and
      manner in which an application for refund can be made and the substantive
E     provisions of the CGST Act cannot, it is urged, be curtailed by making a
      contrary rule. The above submission which seeks to apply the doctrine
      of ultra vires is based on the hypothesis that the rule is not in line with
      Section 54(3). The submission, in other words, is based on the assumption
      that Section 54(3) allows for a refund of unutilized ITC as a result of an
      inverted duty structure due to input goods as well as input services.
F
              87. The second limb of Mr Sridharan’s submission is that any
      rules framed under Section 164 of the CGST Act must be for “carrying
      out the provisions of the Act”. According to the submission, Section
      54(3) provides for entitlement to refund of unutilized ITC, its quantum
      and for cases in which refund is to be granted. This is a complete code
G     which does not require any rules for its operations and there is no
      reference in Section 54(3) enabling the Government to frame rules in
      this regard. Hence, the exercise of the rule making power is urged to be
      unnecessary and unwarranted.

H
    UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                            265
        [DR DHANANJAYA Y CHANDRACHUD, J.]

        88. The rule-making power under Section 164(1) of the CGST            A
Act may be exercised in numerous situations. As we have already noticed
earlier in this judgment accumulation of credit may occur due to a variety
of reasons including the absence of outwards supplies in a tax period,
making supplies at a loss including by discount or predatory pricing, bulk
purchase of inputs, large opening balance of credit or change in the rate
                                                                              B
of tax during the tax period. A rule providing for identifying unutilized
ITC which is attributable to supplies having an inverted duty structure
and bifurcating it from credit which has accumulated due to other causes
would be a rule required for carrying out the provisions of the Act. A
second instance to illustrate the same point is that a rule may provide a
proportionate formula for determining the pro rata amount of ITC relatable    C
to the inverted duty structure vis-à-vis the total turnover. Such a formula
is necessary where the assessee is engaged in outward supplies involving
an inverted duty structure as well as those not involving an inverted duty
structure. In fact, Mr Sridharan in his submissions also accepts that
such a formula would be a rule made for carrying out provisions of the
                                                                              D
Act. The third illustration in the link is with reference to exports. Under
the CGST Act, ITC relatable to exports (which are zero-rated supplies)
has to be refunded. The assessee may have both domestic sales as well
as exports in which event there is a need for a proportionate formula.
Rule 89(4) provides a formula for refund of ITC to cover a situation in
which zero-rated supplies of goods or services or both has been done          E
without payment of tax under bond or letter of undertaking in accordance
with Section 16(3) of the IGST Act.
        89. Mr Sridharan, while arguing that Section 54(3) is a complete
code in itself and does not warrant a rule to further the provisions of the
Act, fairly concedes in his written note that a formula maybe required        F
for bifurcating the accumulated ITC for the purpose of refund. According
to the illustration which has been furnished by Mr Sridharan in his written
note, where an assessee has supplies which fall under an inverted duty
structure and supplies which do not, a refund of unutilized ITC can be
availed of only related to the former but not the latter. A formula would
be required to compute the ITC attributable to the two categories so that     G
a refund is granted to the former and not the latter. Rule 89(5) estimates
the refund attributable to the inverted duty structure by adopting a
proportionate turnover basis, that is by dividing the turnover of inverted
duty structure supplies by the adjusted total turnover and multiplying it
                                                                              H
266               SUPREME COURT REPORTS                         [2021] 15 S.C.R.


A     with the ‘Net ITC’. The submission proceeds to concede that the need
      and rationale for the formula contained in Rule 89(5) in considering the
      turnover of supplies relating to inverted duty structure vis-à-vis overall
      turnover is “understandable and reasonable”.
             90. The grievance however is that Rule 89(5) goes beyond the
B     “provisions of the Act” when in the garb of fixing a formula, it restricts
      the refund of ITC to input goods by denying ITC of input services. This
      is done by defining ‘Net ITC’ to mean ITC availed of inputs. The
      gravamen of the challenge is that this consequently ignores ITC relatable
      to input services. In other words, the submission is that Rule 89(5) cannot
      be construed to be a rule for carrying out the “provisions of the Act”.
C
             91. Mr V Sridharan has also submitted that in case a rule restricts
      the purpose of the legislation, it can be struck down if it is ultra vires the
      principal statute. This is because despite a provision for laying rules
      before a House of Parliament, subjecting them to the procedure for
      modification and annulment, a rule can never be equated with the process
D     of legislation since in particular the rule lacks the assent of the President
      or the Governor as the case may be. In support of his submission, he has
      relied on the decision of a Constitution Bench in Kerala State Electricity
      Board v. Indian Alluvium Co. Ltd.49 and the decision in Bharat Hari
      Singhania v. Commissioner of Wealth Tax (Central)50 rendered by
E     a three judge Bench.
              92. The second limb of the line of challenge is that even though
      the rules are required to be recommended by the GST Council this will
      not elevate them to the status of a law enacted by the legislature. The
      submission which has been urged by Mr V Sridharan proceeds on an
F     underlying assumption which is that Rule 89(5) by restricting the definition
      of Net ITC to mean ITC availed on input goods is an affront to Section
      54(3). It is on this foundation, that it has been urged that a rule which is
      contrary to the statute cannot be saved merely on the ground that either
      (i) the rule has been laid before Parliament and is subject to its power of
      modification annulment or amendment; or (ii) the rule was made on the
G     recommendations of the GST Council. The application of the second
      layer of the argument does not arise in the present case for the simple
      reason that Rule 89(5) in defining Net ITC to mean “input tax credit
      availed on inputs” does not transgress the statutory restriction which is

contained in proviso (ii) of Section 54(3). The challenge to Rule 89(5) as      A
a piece of delegated legislation on the ground that it is ultra vires Clause
(ii) of the first proviso to Section 54(3) is therefore lacking in substance.
As reasoned in the earlier part of this judgment, Clause (ii) of the first
proviso is not merely a condition of eligibility for availing of a refund but
a substantive restriction under which a refund of unutilized ITC can be
                                                                                B
availed of only when the accumulation is relatable to an inverted duty
structure, namely the tax on input goods being higher than the rate of tax
on output supplies. There is therefore no disharmony between Rule 89(5)
on the one hand and Section 54(3) particularly Clause (ii) of its first
proviso on the other hand.
      93. For the sake of clarity, it is necessary to reproduce para 24.6       C
and para 24.7 of the written submissions of Mr V Sridharan:
      “24.5 Similarly, this… court has in several cases extended the
      benefit of exemption/ lower rate in case where such denial to a
      particular case was ultra vires or unconstitutional, thereby enlarging
      the scope of beneficial provision.                                        D

      24.6 In the present case, challenge to the vires of Rule 89(5) is
      only because of definition of Net ITC in Explanation to the said
      rule which defines “Net ITC” as under:
      “Net ITC” shall mean input tax credit availed on inputs during the        E
      relevant period other than the input tax credit availed for which
      refund is claimed under sub-rules (4A) or (4B) or both”
      94. Mr Sridharan urges that the words ‘inputs’ in Explanation (a)
to Rule 89(5) be struck down as being severable to bring it “entirely in
line with the main provision”. We are unable to accept this submission.         F
Explanation (a) to Rule 89(5) in defining ‘Net ITC’ to mean ITC availed
on inputs (goods) is, as a matter of fact, entirely in line with the main
provision, Section 54(3). On the contrary, to accept the submission of
Mr Sridharan, would expand the ambit of Rule 89(5) beyond the terms
governing the admissibility of a refund under Section 54(3) and would be
hence impermissible.                                                            G
      G.3 The validity of the formula prescribed in Rule 89(5)
     95. Mr G Natarajan, Mr Sujit Ghosh, learned Counsel, and
Mr V Sridharan, learned Senior Counsel, have also urged an alternative
submission for the challenge to Rule 89(5). It has been submitted that
                                                                                H
268            SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A     the formula prescribed in Rule 89(5) which seeks to grant refund of the
      ITC accumulated on account of input goods, is inherently flawed and
      will lead to anomalous results. The alternative submission is made on the
      assumption that Section 54(3)(ii) read with Rule 89(5) is restricted to
      refund of ITC accumulated on account of input goods only, and not input
      services.
B
              96. Mr G Natarajan, learned Counsel appearing on behalf of the
      intervenor, has submitted that as it was originally framed, ‘Net ITC’ in
      Rule 89(5) allowed for a refund on account of an inverted duty structure
      both for input goods and input services. The position was amended initially
      on 18 April 2018 with prospective effect and thereafter on 13 June 2018
C     with retrospective effect on 1 July 2017. The formula prescribed in Rule
      89(5) seeks to identify the quantum of ITC availed on input goods
      attributable to the outward supplies having an inverted rate structure.
      From such quantum of ITC on input goods, the tax payable by the supplier
      on such inverted rated supplies of goods and services is reduced to arrive
D     at the quantum of credit accumulating on account of inverted rate
      structure, which is eligible for refund. The submission of Mr Natarajan
      is that in the formula prescribed under Rule 89(5), while reducing “tax
      payable on such inverted rated supplies of goods or services”, the tax-
      payer should first be allowed to utilize the ITC availed on input services
      which is otherwise not eligible for refund. If the formula prescribed under
E     Rule 89(5) is not construed in the above manner, it is alleged that it will
      lead to inequality between taxpayers dealing with outward supplies
      involving only an inverted rate structure (single line of goods) and
      taxpayers dealing with outward supplies having both an inverted rate
      structure and those not having inverted rate structure. Thus, it has been
F     submitted that the Court should read down the formula prescribed in
      Rule 89(5) to the effect that while calculating the refund entitlement as
      the difference between Net ITC and tax payable on such supplies having
      inverted rate structure, it is presumed that the ITC accumulated on
      account of input services be allowed to be used for payment of tax
      payable on inverted goods and services, and the remaining balance of
G     tax, which is paid out of accumulated ITC on account of input goods, is
      deducted from Net ITC in the formula.
              97. Mr G Natarajan’s submission indicates an aberration where
      a registered person with a single product with an inverted duty structure
      is neither able to use the unutilized ITC for the payment of tax on output

        [DR DHANANJAYA Y CHANDRACHUD, J.]

supply nor is allowed a refund. On the other hand, a registered person        A
with products involving an inverted duty structure and otherwise, is in a
position to utilise the ITC availed on input services for payment of tax on
turnover not having an inverted rate structure. Mr G Natarajan has given
the following example:
                                                                              B




                                                                              C




                                                                              D




                                                                              E




      98. The submission of Mr Natarajan has also been supported by
                                                                              F
Mr V Sridharan in rebuttal. The formula in Rule 89(5) is reproduced
below:
      “Maximum Refund Amount=
      {(Turnover of inverted rated supply of goods and services) x Net
      ITC ÷ Adjusted Total Turnover} ? tax payable on such inverted           G
      rated supply of goods and services”
      (emphasis supplied)
        99. Mr V Sridharan has urged that the second leg of the formula,
that is, “tax payable on such inverted rated supply of goods and services”
                                                                              H

A     takes into account the entire tax payable on output supplies. In reality,
      the tax payable on output supplies would have been discharged by utilising
      the ITC on input goods and input services. However, the formula under
      Rule 89(5) presumes that nothing has been utilised from the ITC on
      input services and the entire tax on output supplies is discharged by
      utilising ITC on input goods. It was urged that although the stated
B
      objective of the formula is to grant refund of unutilised ITC accumulated
      on account of input goods, by deducting the entire sum of tax payable on
      output supplies, the quantum of such refund is reduced and the cascading
      effect of taxes is maximised. As a solution to the said anomaly, Mr
      Sridharan has proposed that for the purposes of Rule 89(5), an assumption
C     must be made that ITC accumulated on account of input services, which
      is not refundable under Section 54(3), is used for discharging the output
      tax payable on inverted rate supply of goods and services. The remaining
      balance of output tax, must be then presumed to have been discharged
      from the ITC accumulated on account of input goods and it is only this
      remaining balance that should be deducted from the formula to calculate
D
      the refund. In other words, Mr Natarajan and Mr Sridharan propose an
      order of utilisation in the formula by which the ITC accumulated on
      account of input services is used first for discharging the tax liability and
      only then is the ITC accumulated on account of input goods used. During
      the course of his submissions, Mr Sridharan has relied on the decision of
E     this Court in Commissioner of Income Tax, Coimbatore v. Lakshmi
      Machine Works51 and has urged before us to adopt a purposeful and
      schematic interpretation to the formula which will make it comparable
      and workable.
              100. Mr Sujit Ghosh has urged before us that the formula in Rule
F     89(5) creates a distinction between suppliers of services having a higher
      component of input goods than input services as against suppliers of
      services having a higher component of input services than input goods.
      In his submissions, Rule 89(5) would favour the former as they would be
      entitled to a larger quantum of refund on account of more use of input
      goods.
G
            101. In response to these submissions, Mr N Venkataraman,
      learned ASG, has conceded that certain inadequacies might exist in the
      formula. However, he has sought to justify the need for a formula in
      Rule 89(5). The ASG has submitted that under the scheme of the CGST
      51

Act, the accumulated ITC arising out of input goods and input services           A
is booked into the electronic credit ledger and is to be utilised thereafter
for payment of tax on outward supplies on goods and services in
accordance with Section 49 of the CGST Act. Once payments are made
from the electronic ledger, the remaining quantum of unutilised ITC
becomes one homogenous nucleus and it is impossible to attribute the
                                                                                 B
unutilised ITC to its source, that is, it cannot be identified whether the
balance unutilised ITC is arising from input goods or input services. In
order to bifurcate the unutilised ITC into input goods and input services
for the purpose of granting refund in accordance with Section 54(3)(ii)
on ITC on inputs, Rule 89(5)3 has resorted to prescribing a formula to
legally dissect the unutilised ITC. The learned ASG has urged that the           C
prescription of formulae to artificially determine refund or utilisation is a
common practice in the field of taxation and was used prior to the
enactment of the CGST Act in MODVAT/CENVAT Rules for
determining quantum of eligibility of credit. Another instance is Rule 42
and 43 of the CGST Rules 2017 which provide specific formulae in
                                                                                 D
restricting the ITC when a registered supplier uses input goods, input
services and capital goods for purpose of business and other than business
purposes.
        102. The ASG, having justified the need for a formula, has then
argued that a formula prescribed by delegated legislation may not be
perfect and may have certain aberrations. However, a wide discretion is          E
given to the policy makers in this regard and only if the formula is arbitrary
and violative of Article 14 of the Constitution, can it be struck down. For
this, the ASG has relied on the decision of a Constitution Bench of this
Court in RK Garg v. Union of India52, where it was observed that
economic legislation ought not to be measured by abstract symmetry,              F
since it is essentially empirical in nature and is based on experimentation.
We note however, that the ASG has not refuted the anomalies point out
by the Counsel for the assessees.
       103. In our view, the justification of the formula under Rule 89(5)
given by the ASG to create a legal bifurcation is valid. In this context, it     G
would be material to advert to the provisions of Rule 42. Rule 42(1)
provides that the ITC in respect of input goods or input services which
attract the provisions of sub-Section (1) or sub-Section (2) of Section 17
being partly used for the purpose of business and partly for other purposes

A     or partly used for affecting taxable supplies including zero rated supplies
      and partly for effecting exempts supplies shall be attributed for the
      purposes of business or for effecting taxable supplies in the manner
      which is indicated in the Rule. Sub-Section (1) of Section 17 provides
      that where the goods and services or both are used by a registered
      person partly for the purposes of any business and partly for any other
B
      purpose, the amount of credit shall be restricted to so much of the input
      tax as is attributable to the purpose of its business. Sub-Section (2) of
      Section 17 provides that where the goods or services or both are used
      by a registered person partly for effecting taxable supplies including
      zero rated supplies under the CGST Act or under the IGST Act and
C     partly for effecting exempt supplies the amount of credit shall be restricted
      to so much of the input tax as is attributable to the taxable supplies
      including zero rated supplies. Rule 42, in other words, provides for the
      manner in which the attributions of ITC in respect of the input or input
      services under sub-Sections (1) or (2) of Section 17 shall be carried out.
      Rule 43 similarly provides the manner in which ITC in respect of capital
D
      goods attracting the provisions of sub-Section (1) of Section 17, used
      partly for business and partly for other purposes or partly for effecting
      taxable supplies including zero rated supplies and partly for effecting
      exempt supplies would be attracted to the purpose of business or for
      effecting taxable supplies. Both Rules 42 and 43 provide for a formula
E     for attribution. Rule 86 provides for the maintenance of an electronic
      credit ledger. Rule 89(5) provides for a refund. In both sets of rule clusters,
      Rules 42 and 43 on the one hand and Rule 89(5) on the other hand, a
      formula is used for the purpose of attribution in a post assimilated scenario.
      The use of such formulae is a familiar terrain in fiscal legislation including
      delegated legislation under parent norms and is neither untoward nor
F
      ultra vires.
               104. We now turn to the submissions of the counsel for the
      assessees regarding the anomalies in the formula. In our view, the
      submission of Mr Sujit Ghosh, that the formula creates a distinction
      between suppliers having a higher component of input goods than those
G     having a higher component of input services, and must be read down
      accordingly, must be rejected. The purpose of the formula in Rule 89(5)
      is to give effect to Section 54(3)(ii) which makes a distinction between
      input goods and input services for grant of refund. Once the principle
      behind Section 54(3)(ii) of the CGST Act is upheld, the formula cannot
H     be struck down merely for giving effect to the same.

        [DR DHANANJAYA Y CHANDRACHUD, J.]

       105. The aberrations which have been pointed out by the Mr              A
Sridharan and Mr G Natarajan certainly indicate that the formula is not
perfect. The formula makes a presumption that the output tax payable
on supplies has been entirely discharged from the ITC accumulated on
account of input goods and there has been no utilisation of the ITC on
input services. While a similar formula is provided in Rule 89(4) with
                                                                               B
regard to zero rated supplies, in that case, the ‘Net ITC’ includes input
goods and input services and thus, there is no imbalance between the
different components of the formula. The formula prescribed in Rule
89(5) however, seeks to deduct the total output tax from only one
component of the ITC, namely ITC on input goods. This in our view is at
odds with reality, where the ITC on both input goods and input services        C
is accumulated in the electronic ledger and is then utilised for the payment
of output tax. In making such an assumption, the formula tilts the balance
in favour of the Revenue by reducing the refund granted. We are equally
cognizant of the fact that the proposed solution, that is prescribing an
order of utilisation of the ITC accumulated on input services and input
                                                                               D
goods, may tilt the balance entirely in favour of the assessee as that
would make a contrary assumption that the output tax is discharged by
the ITC accumulated on account of input services entirely. Another
possible solution could be that the Rule itself provides for a statutory
assumption or a deeming fiction of utilisation of a certain percentage of
ITC on input services towards the payment of output tax for the purpose        E
of calculation of refund.
       106. While we are alive to the anomalies of the formula, an anomaly
per se cannot result in the invalidation of a fiscal rule which has been
framed in exercise of the power of delegated legislation. In RK Garg
(supra), Justice P N Bhagwati (as the learned Chief Justice then was)          F
speaking for the Constitution Bench underscored the importance of the
rationale for viewing laws relating to economic activities with greater
latitude than laws touching civil rights. The Court held:
      “8. Another rule of equal importance is that laws relating to
      economic activities should be viewed with greater latitude than          G
      laws touching civil rights such as freedom of speech, religion etc.
      It has been said by no less a person than Holmes, J., that the
      legislature should be allowed some play in the joints, because it
      has to deal with complex problems which do not admit of solution
      through any doctrinaire or strait-jacket formula and this is
                                                                               H
274      SUPREME COURT REPORTS                           [2021] 15 S.C.R.


A     particularly true in case of legislation dealing with economic matters,
      where, having regard to the nature of the problems required to be
      dealt with, greater play in the joints has to be allowed to the
      legislature. The court should feel more inclined to give judicial
      deference to legislative judgment in the field of economic regulation
      than in other areas where fundamental human rights are involved.
B
      Nowhere has this admonition been more felicitously expressed
      than in Morey v. Doud [351 US 457 : 1 L Ed 2d 1485 (1957)]
      where Frankfurter, J., said in his inimitable style:
         “In the utilities, tax and economic regulation cases, there are
C        good reasons for judicial self-restraint if not judicial deference
         to legislative judgment. The legislature after all has the
         affirmative responsibility. The courts have only the power to
         destroy, not to reconstruct. When these are added to the
         complexity of economic regulation, the uncertainty, the liability
         to error, the bewildering conflict of the experts, and the number
D        of times the judges have been overruled by events — self-
         limitation can be seen to be the path to judicial wisdom and
         institutional prestige and stability.”
      The Court must always remember that “legislation is directed to
      practical problems, that the economic mechanism is highly sensitive
E     and complex, that many problems are singular and contingent, that
      laws are not abstract propositions and do not relate to abstract
      units and are not to be measured by abstract symmetry”; “that
      exact wisdom and nice adaption of remedy are not always possible”
      and that “judgment is largely a prophecy based on meagre and
F     uninterpreted experience”. Every legislation particularly in
      economic matters is essentially empiric and it is based on
      experimentation or what one may call trial and error method
      and therefore it cannot provide for all possible situations or
      anticipate all possible abuses. There may be crudities and
      inequities in complicated experimental economic legislation
G     but on that account alone it cannot be struck down as invalid.
      The courts cannot, as pointed out by the United States
      Supreme Court in Secretary of Agriculture v. Central Roig
      Refining Company [94 L Ed 381 : 338 US 604 (1950)] be
      converted into tribunals for relief from such crudities and
H     inequities. There may even be possibilities of abuse, but
   UNION OF INDIA v. VKC FOOTSTEPS INDIA PVT LTD.                                275
       [DR DHANANJAYA Y CHANDRACHUD, J.]

      that too cannot of itself be a ground for invalidating the                 A
      legislation, because it is not possible for any legislature to
      anticipate as if by some divine prescience, distortions and
      abuses of its legislation which may be made by those subject
      to its provisions and to provide against such distortions and
      abuses. Indeed, howsoever great may be the care bestowed
                                                                                 B
      on its framing, it is difficult to conceive of a legislation which
      is not capable of being abused by perverted human ingenuity.
      The Court must therefore adjudge the constitutionality of such
      legislation by the generality of its provisions and not by its crudities
      or inequities or by the possibilities of abuse of any of its provisions.
      If any crudities, inequities or possibilities of abuse come to light,      C
      the legislature can always step in and enact suitable amendatory
      legislation. That is the essence of pragmatic approach which must
      guide and inspire the legislature in dealing with complex economic
      issues.”                                        (emphasis supplied)
        107. The dictum in RK Garg (supra) squarely applies to the present       D
case in which the Government has exercised its powers of delegated
legislation to frame a formula, which has certain inequities. However,
these inequities are to be ironed out by the Government in the course of
the application of the formula. We are affirmatively of the view that this
Court should not in the exercise of the power of judicial review allow           E
itself to become a one-time arbiter of any and every anomaly of a fiscal
regime despite its meeting the jurisdictional framework for the validity
of the legislation, including delegated legislation.
       108. Mr Sridharan had also urged that the formula may be read
down as was done by this Court in Lakshmi Machine Works (supra).                 F
In this case, the Court was faced with a question of whether excise duty
and sales tax were to be included in the ‘total turnover’, which was a
denominator in the formula prescribed under Section 80-HHC(3) of the
Income Tax Act 1961 for the purpose of arriving at the deduction from
profits retained for export business. In order to arrive at the deduction,
the formula apportioned business profits by the ratio of export turnover         G
to total turnover. Various amendments had been made by the legislature
to the formula in Section 80-HHC(3) to make the formula workable.
The Court, speaking through Justice SH Kapadia (as the learned Chief
Justice then was), observed that
                                                                                 H
276      SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A     “21. According to The Law and Practice of Income Tax by Kanga
      and Palkhivala, the word “profits” in Section 28 should be
      understood in normal and proper sense. However, subject to special
      requirements of the income tax, profits have got to be assessed
      provided they are real profits. Such profits have got to be
B     ascertained on ordinary principles of commercial trading and
      accounting. However, the Income Tax Act has laid down certain
      rules to be applied in deciding how the tax should be assessed and
      even if the result is to tax as profits what cannot be construed as
      profits, still the requirements of the Income Tax Act must be
C     complied with. Where a deduction is necessary in order to ascertain
      the profits and gains, such deductions should be allowed. Profits
      should be computed after deducting the expenses incurred for
      business though such expenses may not be admissible expressly
      under the Act, unless such expenses are expressly disallowed by
      the Act (see p. 455 of The Law and Practice of Income Tax by
D
      Kanga and Palkhivala). Therefore, schematic interpretation for
      making the formula in Section 80-HHC workable cannot be ruled
      out. Similarly, purposeful interpretation of Section 80-HHC which
      has undergone so many changes cannot be ruled out, particularly,
      when those legislative changes indicate that the legislature intended
E     to exclude items like commission and interest from deduction on
      the ground that they did not possess any element of “turnover”
      even though commission and interest emanated from exports. We
      have to read the words “total turnover” in Section 80-HHC as
      part of the formula which sought to segregate the “export profits”
F     from the “business profits”. Therefore, we have to read the formula
      in entirety. In that formula the entire business profit is not given
      deduction. It is the business profit which is proportionately reduced
      by the above fraction/ratio of export turnover ÷ total turnover which
      constitutes Section 80-HHC concession (deduction). Income in
G     the nature of “business profits” was, therefore, apportioned. The
      above formula fixed a ratio in which “business profits” under
      Section 28 of the Act had to be apportioned. Therefore, one has to
      give weightage not only to the words “total turnover” but also to
      the words “export turnover”, “total export turnover” and “business
      profits”. That is the reason why we have quoted hereinabove

         extensively the illustration from the Direct Taxes (Income Tax)        A
         Ready Reckoner of the relevant word.”
       109. The Court in Lakshmi Machine Works (supra) was dealing
with a question of interpretation, where the formula was silent on inclusion
of sales tax or excise duty, in the definition of total turnover. Thus, a
schematic interpretation was adopted to give effect to the intent of the        B
legislature.
       110. In Commissioner of Income Tax v. HCL Technologies
Limited53, a two judge Bench of this Court considered whether, while
calculating ‘export profit’ for the deduction under Section 10-A of the
                                                                                C
Income Tax Act 1961, software development charges are to be excluded
from the definition of ‘total turnover’. For calculating the export profit,
the total profits of the business were apportioned by the ratio of export
turnover to total turnover. The issue was complicated as these charges
were allowed to be deducted from export turnover, which was a
component of the total turnover and the numerator in the formula.               D
However, the Revenue had denied the deduction from the total turnover,
the denominator. The Court interpreted and revised the formula as
otherwise it would lead to undesirable results. In doing so, Justice RK
Agrawal observed that
                                                                                E
         “16. The respondent Company has claimed deduction under Section
         10-A as per certificates filed on Form 56-F. The respondent, while
         computing the deduction, has taken the same figure of export
         turnover as of total turnover. […]
         17. In the above backdrop, we are of the opinion that the definition   F
         of total turnover given under Sections 80-HHC and 80-HHE cannot
         be adopted for the purpose of Section 10-A as the technical
         meaning of total turnover, which does not envisage the reduction
         of any expenses from the total amount, is to be taken into
         consideration for computing the deduction under Section 10-A.
                                                                                G
         When the meaning is clear, there is no necessity of importing the
         meaning of total turnover from the other provisions. If a term is
         defined under Section 2 of the IT Act, then the definition would be
         applicable to all the provisions wherein the same term appears. As

A              the term “total turnover” has been defined in the Explanation to
               Sections 80-HHC and 80-HHE, wherein it has been clearly stated
               that “for the purposes of this section only”, it would be applicable
               only for the purposes of those sections and not for the purpose of
               Section 10-A. If denominator includes certain amount of
B              certain type which numerator does not include, the formula
               would render undesirable results.
               […]
               22. In the instant case, if the deductions on freight,

C
               delivery of computer software under Section 10-A of the IT
               Act are allowed only in export turnover but not from the
               total turnover then, it would give rise to inadvertent,
               unlawful, meaningless and illogical result which would cause
               grave injustice to the respondent which could have never
D              been the intention of the legislature.
               23. Even in common parlance, when the object of the formula is
               to arrive at the profit from export business, expenses excluded
               from export turnover have to be excluded from total turnover also.
               Otherwise, any other interpretation makes the formula unworkable
E
               and absurd. Hence, we are satisfied that such deduction shall be
               allowed from the total turnover in same proportion as well.

      appellants argued that the amended Rule did not provide the assessee
      with the right to claim before the assessing officer that there was no
G
      “concession” in the matter of rent with respect to the accommodation
      provided and thus, Section 17(2) and Rule 3 were not applicable. An
      argument was raised to “read down” the Rule by introducing the principle

       [DR DHANANJAYA Y CHANDRACHUD, J.]

of audi alteram partem. Rejecting this argument, the Court, speaking           A
through Justice CK Thakker, noted that
      “55. The doctrine of “reading down” is well known in the field of
      constitutional law. Colin Howard in his well-known
      work Australian Federal Constitutional Law states:
                                                                               B
      Reading down puts into operation the principle that so far as it is
      reasonably possible to do so, legislation should be construed as
      being within power. It has the practical effect that where an Act is
      expressed in language of a generality which makes it capable, if
      read literally, of applying to matters beyond the relevant legislative
                                                                               C
      power, the Court will construe it in a more limited sense so as to
      keep it within power.”
      The Court after reviewing the judicial precedents on this point
observed:
      “61. But it is equally well settled that if the provision of law         D
      is explicitly clear, language unambiguous and interpretation
      leaves no room for more than one construction, it has to be
      read as it is. In that case, the provision of law has to be
      tested on the touchstone of the relevant provisions of law
      or of the Constitution and it is not open to a court to invoke           E
      the doctrine of “reading down” with a view to save the
      statute from declaring it ultra vires by carrying it to the point
      of “perverting the purposes of the statute.
      […]
                                                                               F
      65. As we have already indicated earlier, Rule 3 prior to its
      amendment in 2001 was totally different. It dealt with the method
      of calculation of concession keeping in view the concept of “fair
      rental value”. In the light of the principle and phraseology in Rule
      3, the rule-making authority provided an opportunity to the assessee
      to satisfy the assessing officer that the rent sought to be recovered    G
      from the employee could not be said to be “concession” as it was
      “fair rent”, “reasonable rent”, “market rent” or “standard rent’.
      When the rule is amended and the concept of “fair rental value”
      has been done away with and the only method which has been
                                                                               H
280             SUPREME COURT REPORTS                          [2021] 15 S.C.R.


A           adopted is to calculate the rent on the basis of population of the
            city in question, it cannot be successfully contended that the
            intention of the rule-making authority was to afford an opportunity
            to the assessee to convince the assessing officer that the rent
            recovered by the employer from his employee was not in the nature
B           of concession. Nor a court of law would, by interpretative process,
            grant such opportunity to the assessee so as to enable him to
            convince the assessing officer that the rent fixed was not covered
            by Section 17(2)(ii) of the Act and therefore was not a “perquisite”.
            We are, therefore, unable to accept the argument of Mr Salve and
C           allow import of the principles of natural justice in Rule 3.”
                                                          (emphasis supplied)
              111. The above judicial precedents indicate that in the field of
      taxation, this Court has only intervened to read down or interpret a formula
      if the formula leads to absurd results or is unworkable. In the present
D     case however, the formula is not ambiguous in nature or unworkable,
      nor is it opposed to the intent of the legislature in granting limited refund
      on accumulation of unutilised ITC. It is merely the case that the practical
      effect of the formula might result in certain inequities. The reading down
      of the formula as proposed by Mr Natarjan and Mr Sridharan by
E     prescribing an order of utilisation would take this Court down the path of
      recrafting the formula and walk into the shoes of the executive or the
      legislature, which is impermissible. Accordingly, we shall refrain from
      replacing the wisdom of the legislature or its delegate with our own in
      such a case. However, given the anomalies pointed out by the assessees,
F     we strongly urge the GST Council to reconsider the formula and take a
      policy decision regarding the same.
            H Conclusion
             112. Having devoted our attention to the submissions at the Bar,
      we have come to the conclusion that the judgment of the Madras High
G
      Court needs to be affirmed by dismissing the appeals challenging that
      verdict while the appeals against the judgment of the Gujarat High Court
      by the Union of India should be allowed.
            113. The Division Bench of the Gujarat High Court having examined
H     the provisions of Section 54(3) and Rule 89(5) held that the latter was

         [DR DHANANJAYA Y CHANDRACHUD, J.]

ultra vires. In its decision in VKC Footsteps India Pvt. Ltd. (supra),                A
the Gujarat High Court held that by prescribing a formula in sub-Rule
(5) of Rule 89 of the CGST Rules to execute refund of unutilized ITC
accumulated on account of input services, the delegate of the legislature
had acted contrary to the provisions of sub-Section (3) of Section 54 of
the CGST Act which provides for a claim of refund of any unutilized                   B
ITC. The Gujarat High Court noted the definition of ITC in Section
2(62) and held that Rule 89(5) by restricting the refund only to input
goods had acted ultra vires Section 54(3). The Division Bench of the
Madras High Court on the other hand while delivering its judgment in
Tvl. Transtonnelstory Afcons Joint Venture (supra) declined to follow                 C
the view of the Gujarat High Court noting that the proviso to Section
54(3) and, more significantly, its implications do not appear to have been
taken into consideration in VKC Footsteps India Pvt. Ltd. (supra)
except for a brief reference. Having considered this batch of appeals,
and for the reasons which have been adduced in this judgment, we affirm
                                                                                      D
the view of the Madras High Court and disapprove of the view of the
Gujarat High Court. We accordingly order and direct that:

               of the Gujarat High Court dated 4 July 2020 in VKC
               Footsteps India Pvt. Ltd. (supra) and connected cases                  E
