Holding

The Supreme Court dismissed the petition, holding that the butter was safe within AERB’s permissible limits and that the court should not intervene in the technical scientific assessment.

Summary

The petitioners sought a writ of mandamus to stop the release of 7,500 cartons of Irish butter imported for the Operation Flood programme, alleging that the butter was contaminated with radioactive fallout from the Chernobyl disaster. The Bombay High Court declined to issue such a writ, holding that the matter was technical and that the authorities had complied with scientific testing. The Supreme Court appointed a three‑member expert committee which examined the radiological data and concluded that the butter contained Cs‑137 well below the permissible limit of 40 Bq/kg set by the Atomic Energy Regulatory Board (AERB) and was therefore safe for human consumption. Relying on the committee’s opinion, international radiological standards, and the fact that AERB’s limits are among the lowest worldwide, the Court dismissed the petition, stating that the judiciary should not intervene in complex scientific determinations and that no labeling direction was warranted. The order of status‑quo by the High Court was discharged.

Issues considered

Whether the imported Irish butter exceeded the radioactive contamination limits prescribed by the Atomic Energy Regulatory Board.
Whether the Supreme Court can issue a mandamus directing the respondents to forbear from releasing the butter.
Whether the permissible limits set by AERB are valid and sufficient to ensure safety for public consumption.
Whether a labeling requirement for the butter is necessary.

Seeking brm on release of Irish. butter for public distribution and
human consumption on the ground that the butter was contaminated by
nuclear fall-out after Chernobyl disaster .
. --!..
This special leave petition was directed against the judgment and C
order of the Bombay High Court, declining to issue a writ in the nature
of Mandamuj and other appropriate writ, directions or orders, direct-
ing the respondents to forbear from releasing 7500 cartons (200 MT) of
Irish butter imported into India for operation Flood Programme,
supplied to the Greater Bombay Milk Scheme by respondent No. : , D
National Dairy Development Board, on the ground that the butter was
contaminated by nuclear fall-<iut.

Soon after the Chernobyl disaster, when it was realised that the
imported milk and food products particularly from the EEC countries
had the possibility of radio-active contamination, the Bhabha Atomic E
Research Centre took up the matter with the respective agencies and
advised them to get the representative samples for radio-active analysis
before releasing them for public distribution in India.

This Court appointed a Committee of three experts,
F
(i) Professor M.G.K. Menon, Member Planning Commission & Scien-
tific Advisor to the Prime Minister (2) Dr. P .K. Iyenger, Director
Bhabha Atomic Research Centre, Bombay and (3) G.V.K. Rao, Vice--
chairman, Economic & Planning Council, Govt. of Karnataka, Banga-
lore to give its opinion on the question whether milk and dairy products
and other food products containing man-made radionuclides within G
permissible levels fixed by the Atomic Energy Regulatory Board on
27th August, 1987, were safe and/or harmless for human consumption.
The Committee of Experts examineri the question in depth and by its
report dt. February 19, 1988, expressed its opinion that the consign-
ment of the imported butter was safe and harmless for human con-
sumption. A

Dismissing the special leave petition, the Court, i
HELD: There was no substance in any of the objections formu-
lated by the petitioners. In its most recent recommendations, the Inter-
national Commission on Radiological Protection observed that 'limits
for. the inhalation or ingestion of radio-active material depend on the
B concentration of those materials in limiting target organs'. The
petitioners showed different permissible limits in different countries as -..\
France, UK, E.E.C., and Australia at 3700, 2000, 370 and iOO. These
I are the limits of radioactivity prescribed by these countries for
imported foodstuffs. As against these, the prescribed limit for India
'-f
1 '
admittedly is 40 (bq!I). II20C-E]
c The analysis of the imported butter by the Bhabha Atomic Re-
search Centre, which according to the Committee of Experts must be
treated to be accurate, showed the presence in the samples of imported
butter of CS-i37 at limits ranging from 0.6 Bq/kg to 2.9 Bq/kg. The
petitioners relied upon letters sent by some internationally known scien-
D tists including Nobel laureates tending to show that it was desirable to
avoid foodstuffs containing low level radio-activity which, according to
them, might in the long run prove to be hazardous. Those letters were
in general terms and only represented a particular school of thought.
Surely, the Committee of Experts comprising two eminent scientists
and an equally well-known Agro-Economist, was well aware of this
E point of view. I120E-G I

The Court could not accept the contention of the petitioners that
the Court should give a direction that all articles of foodstuffs using the
imported butter should carry a label 'Manufactured out of Butter
Imported from the EEC countries.' Il20G-H]
F
The Court shared the opinion of this Court expressed in the
Vincent's case, where a direction was sought in public interest for
banning the import, manufacture, sale and distributiOn of certain drugs
recommended by the Drugs Consultative Committee and this Court had
observed that having regard to the magnitude, complexity and technical
G nature of the enquiry involved in the matter and keeping in view the
far-reaching implications of the total ban of certain medicines for
which the petitioner had prayed, it must be indicated that a judicial
proceeding of the nature initiated was not an appropriate one for
determination of such matters. II21A-C]

ORDER

This special leave petition is directed against the judgment and
order of the Bombay High Court dated November 24, 1987 declining
to·issue a writ in the nature of mandamus and other appropriate writs,
directions or orders under Art. 226 of the Constitution as prayed for E
by the petitioners to direct the respondents to forbear from releasing
•
7500 cartons (200 MT) of Irish butter imported into India under the
L EEC Grant-in-Aid for Operation Flood Programme, supplied to_ the
Greater Bombay Milk Scheme by respondent No. 2 National Dairy
Development Board, on the ground that the butter was contaminated
~~u~~- F

From the counter-affidavit filed on behalf of respondent No.1
Union of India and respondent No. 2 National Dairy Development
Board it appears that soon after the Chernoby 1 disaster when it was
realised that the imported milk and food products particularly from
the EEC countries had the possibility of radio-active contamination, G
and so the Bhabha Atomic Research Centre took up the matter with
).. the respective agencies and advised them to get the representative
samples for radio-active analysis before releasing them for public
distribution in India .. It further appears that the Atomic Energy
Regulatory Board which is a statutory body, has set limits for radio-
activity for imported foodstuffs. In disallowing the writ petition, the H
High Court observed:
118 SUPREME COURT REPORTS [1988] 3 S.C.R.

A
"We are satisfied that the best scientific brain available in
the country has applied itself to the question. The question
ii
is whether in the product with which we are concerned here
there is radioactivity above the permissible limit. This
question has been sought to be ~nswered by the respon-
dents on the basis of laboratory tests conducted on their
B behalf, Fixation of the permissible limit of radioactivity in a
product, naturally, is for the scientists to decide, but the
tests themselves are carried on by persons working in the
laboratory, naturally, again under the guidance of the
scientists concerned. We have not found that any defect is
disclosed in the material which has been placed before us in
the manner of testing. We have also not been shown that
-
c any other better method is "available. Mr. Setalvad appear-
ing for respondent No. 2 has told us that if any other
method of sampling is suggested the respondents will
willingly examine the same and conduct the tests accor-
dingly."
D
At one stage, the High Court felt disturbed about the concept of
the 'permissible limit' and asked counsel appearing for both the sides
to examine the question in the light of certain queries which arose in its
mind. It wanted to know on what basis the permissible limit of radio-
activity was determined, and in particular, whether this permissible
E limit had been determined on the basis of consumption by human
beings of any natural food in which radio-activity was present or was it
based upon the external irraditation, and added:

"This question can, naturally, be answered if there is also -
answer to the question whether natural foods contain re-
F dioactivity under normal circumstances."

The High Court relied upon a letter dated November 13, 1987
from the Secretary, Atomic Energy Regulatory Board produced along
with an affidavit which furnished an answer to the question. As re-
gards the contention that the radio-activity that is found naturally in
G articles of human consumption and the radio-activity that is found in
such articles acquired by pollution are qualitatively different, and
therefore, the concept of permissible limit evolved by the scientists in ..I.,
India should not be accepted, and further that the permissible limit so
evolved based upon studies on articlo for human consumption, which
include articles such as Potassium, was a dangerous concept because
H Potassium and Caesium-137 have different radio-active properties,
DR. S.S. WAGLE v. U.0.1. 119

the High Court declined to be drawn into the controversy which was of
A
a highly technical nature placing reliance to the words of caution
administered by this Court in Vincent v. Union of India, A.LR. (1987)
SC 990. In conclusion, the High Court observed:

"We have already broadly indicated the complicated
natiire of the questions involved. We are also satisfied that B
the authorities concerned are fully aware of the problem at
the highest level. They have adopted methods reg'l!"ded by
them as best suited-methods which have been approved by
scientists. In these circumstances, we do not see how in a
petition under Article 226 of the Constitution it is possible
for us to resolve this controversy."
c
After hearing Ms. Indira Jai Singh, learned counsel for the
petitioners, Shri Atul Setalvad, learned counsel for respondent No. 2
National Dairy Development Board and Shri Kuldeep Singh, learned
Additional Solicitor General at quite some length on January 20, 1988
this Court having given the matter its anxious consideration thought it D
desirable to appoint a committee of three experts, namely (1) Profes-
sor M.G.K. Menon (2) Dr. P.K. Iyengar and (3) G.V.K. Rao to give
its opinion on the following question:

"Whether milk and dairy products and other food products
containing man-made radionuclides within permissible E
levels by the Atomic Energy Regulatory Board on 27th
August, 1987, are safe and/or, harmless for human con-.
sumption."

The Committee of Experts after due deliberation examined the ques-
tion in depth and by its report dated February 19, 1988 has expressed F
its opinion that the consignment of imported butter was safe ahd harm-
less for human consumption. The conclusions reached by the Commit-
tee can best be stated in its own words:

"!. The permissible levels of radioactivity in milk, dairy
and other food products fixed by the Atomic Energy G
Regulatory Board as per its communication of August.27,
1987 have been arrived at after due consideration of ICRP
does limits for the General population.

3. The consumption of milk, dairy and other food pro-

lation, and through-out the year, are safe and harmless." ....
The report of the Committee of Experts shall become and form part of

~-
-
We have heard learned counsel for the petitioners at consider-
c able length on the objections formulated by them in the counter-aft-
idavit and gone through the annexures thereto. We do not find any 1
substance in any of them. In its most recent recommendations, the
International Commission on Radiological Protection observes that
'limits for the inhalation or ingestion of radioactive material depend on
D the concentration of those materials in limiting target organs'. The
petitioners in their counter-affidavit have shown different permissible
limits in different countries such as France, U.K.; E.E.C., and
Australia at 3700, 2000, 370 and 100. These are the limits of radioacti-
vity prescribed by these countries for imported foodstuffs. As against
this, the prescribed limit for India admittedly is 40 (bq/l). As already
E stated, the analysis of the imported butter by the Bhabha Atomic ~
Research Centre which according to the Committee of Experts must
be treated to be accurate, showed the presence in the samples of
imported butter of CS-137 at limits ranging from 0.6 Bq/kg to 2.9.
Bq/kg. The learned counsel for the petitioners read out letters sent in
reply by some internationally known scientists including Nobel
F laureates tending to show that it is desirable to avoid foodstuffs
containing low level radio-activity which according to them might in
~
the long run prove to be hazardous. What is remarkable about these
letters is that they are in general terms and only represent a particular
school of thought. Surely, the Committee of Experts comprising of two
eminent scientists and an equally well-known Agro-Economist was
G well aware of this point of view. Lastly, learned counsel for the
petitioners suggested that the Court should give a direction that all
articles of foodstuffs using the imported butter should carry a label ,t,
'Manufactured Out of Butter Imported From The EEC Countries'.
We are afraid, the contention cannot be accepted.

H In Vincent's case, this Court in dealing with a case where a direc-

REPORT OF THE COMMITTEE

Background

The Hon'ble Supreme Court by its order dated January 20, 1988
c appointed this Expert Committee to give its opinion to the Court on
the following question, arising in the proceedings of the Special Leave
Petition (Civil) No. 15408 of 1987. ·

"Whether milk and dairy products and other food products
D containing man-made radionuclides within permissible
levels by the Atomic Energy Regulatory Board on 27the
August, 1987, are safe and/or, harmless for human con-
sumption".

1. The committe'e examined in detail the Special Leave Petition,
E various affidavits and other supplementary documents sent by the
Hon. Court. The Committee have also deliberated on the issues raised
by the petitioners, and explanations of the respondents for under-
standing the background of the petition.
I

F
2. The internationally followed practices in radiation protection
were examined, and it was observed that the concept of permissible
j-
levels of radioactivity and radiaiion exposure is universally followed
both for occupational workers and members of the public. India is no
exception.

3. After ascertaining this, the Committee went into the basis
G used by Atomic Energy Regulatory Board (AERB) in arriving at the
permissible levels for milk, dairy and food products prescribed by the
Board. It concluded its deliberations by discussing the specific ques-
tion referred to the Committee and arrived at the unanimous opinion
given at the end.

H Scientific Background
DR. S.S. WAGLE v. U.0.1. 123
t l. The issues raised and apprehensions expressed by the petition-
A
ers arise from the fact that Chemebyl reactor accident, which occured
in USSR in April, 1986, deposited radioactivity in measurable and
varying quantities in several European countries. Consequently, the
possibility exists that milk and dairy products droduced soon after the
accident in such countries contain radioactive contamination. The
specific issue raised is· about Irish butter imported into India after the B
}..
J accident. The apprehension is that if such contaminated food products
are consumed by the Indian population, harmful effects may be
caused.

2. On the basis of scientific information available, the following
facts would by the relevant background to take a balanced view on the
issues raised.
c

1. Man has evolved in the background of natural radioactivity,
and atomic and nuclear radiations, which have been present on
the earth since its formation. The important sources of natural
radiation exposures to man have been continuous cosmic radia- D
tions coming from the Sun and Outer space, natural radioactivity
such as due to K-40, and to a lesser extent due to uranium and
thorium and their daughter products in the environment. The
human body itself contains several (of the order of three)
thousands bequerels of radioactivity, mostly due to K--40.
Exposure to natural radiation sources is thus unavoidable. E

The Cosmic ray component of natural radiation exposure
varies with altitude and latitude. Terrestrial component also
varies from place to place due to differences in the concentra-
-~ tions of K--40, uranium and thorium in the soils, Exposure due
\
to inhalation of radon and its daughters, from uranium present F
in the soil, varies even at the same place with the time of the
day and season of the year. Similarly,. concentrations of natural
radionuclides in food items vary depending on the place where
they are produced. Thus, the. total exposure to man from
natural causes varies considerably (upto a factor of 10) in
different parts of India. G

2. The effects of radioactivity or radiation exposure in human
beings are related to the radiation dose delivered· to body
tissues. The radiation dose depends on a number of para-
meters i.e. physical half-life, energy and type of radiation,
biological half-life, sensitive body organ etc. H
124 SUPREME COURT REPORTS 11988] 3 S.C.R.

3. The effect on human body is, thus, determined by the
A
above complex parameters. The human body does not
differentiate between natural and man-made sources of radi-
ation exposure as regards their effects.

4. Consequent to the chernobyl reactor accident, radio-
B active fallout deposited over several European countries.
Ireland was also affected by this radioactive fallout, though to
a smaller extent as compared to several other European
countries, e.g. Sweden, Norway, Poland, Finland, Switzer-
land, etc. The most important radionuclides so dispersed
were I-131, Cs-137 and Sr-90. I-131 being a short-lived
radionuclide (half-life 8 days) was of concern to the countries
c receiving the fallout, and not to India. By the ti~e imported
food items arrived in India, I-131 even if it was present when i
the item was proquced, it must have decayed. Strontium-90
being long lived (half-life 29 years) could have been of con~
cern, but it was deposited in small amounts, and the ratio of
D Sr-90/Cs-137 in milk observed in European countries was of
the order of 1% (UN Scientific Committee on the Effects of
Atomic Radiation draft report No. A/AC. 82/R. 461 dt.
4.4.87, relevant papers annexed to SLP, Additional Docu-
ments submitted by Respondent 2 pp 47-49). Measurements
in India on selected dairy product samples also confirmed
E Sr-90/Cs-137 ratio reported by UNSCEAR to be in the range
0.5-1.5%. In most of the imported milk powder samples
Sr-90 was below detection limits. Therefore, Cs-137 is the
most important loqg-lived radionuclide from the Chernoby 1
accident; life time of Cs-137 is 30 years. Since it can also be
measured in a short-time by a sensitive gamma spectrometer,
F it is the·'ideal radionuclide for screening of imported food
items. It is for these reasons that not only India, but most of
the other countries also adopted Cs-137 measurements for
screening of the imported food items.

5. Direct deposition of radioactive fallout on a grass surface
G (called foliar deposition) can rapidly transfer Cs-137 contami-
nation to milk, through the grass--<:attle-milk pathway.
Therefore, in the first few months after the fallout, there is a
greater possibility of milk and dairy products from such areas.
to be contaminated, as compared to other food ·items. Of
course, over long periods this mode of radioactivity transfer is
H reduced because once Cs-137 deposits on the soil, its up-take
DR. S.S. WAGLE v. U.0:1. 125

by grass through roots is smaller. In view of these facts, milk
A
and dairy prodncts become important items of food which
should be carefully measured for possible contamination.
Since milk is the staple diet of children, they are a particularly
sensitive group of the population.

6. Even though .milk and other dairy products are more B
susceptible to radioactive contamination due to fallout,
amongst various dairy products, butter oil is likely to be less
contaminated with Cs-137. This is because butter oil is .com-
posed of fat, which is separated from the liquid milk fraction
in the process of its manufacture. Caesium compounds being
highly water soluble, almost all of the Cs-137 is left behind in C
the liquid portion .

. 7. The International Commission on Radiological Protection
(ICRP) is an unique international non-governmental body of
professionals from related disciplines involved in:assessing
· radiation effects and recommending guidelines for the protec- D
tion of man and_ his e~vironment_. It was established in 1928.
ICRP recommenda.tions are followed universally. ICRP has
defined ·limits for the general. public as 1 mSv per year
averaged over a life span,_ but in any single year; it should not
exceed 5 mSv. The maximum· permissible limits for food items
,. , etc, are derived by each.country as per its national policy, E
·dietary components etc. Therefore, derived limits for food
items and dairy prod)lcts vary from country to_ country.

8 .. The Atomic Energy Regulatory-.Board (AERB) constitu-
··~
ted by the Government of India in 1983 is the competent
authority for this country. for radilogical protection, and has F
been empowered -to prescribe acceptable limits of radiation
exposure to . occupational workers, and members of the
. public, and to approve acceptable limits of environmental re·
lease of radioactive substances.

9. In arriving at maximum permissiole limits for butter oil, G
milk and other food products, AERB has considered ICRP
J, recommendaiions regarding does limits for the members 9f
• the public and several other factors, e.g. sensitive population
group, dietary pattern etc. It has adopted a more conservative ·
approach than other countries. For example, out of 1 mSv/
year does limit recommended by ICRP, AERB has allowed H
126 SUPREME COURT REPORTS [1988] 3 S.C.R.
'f··
only 10% to the exposure through intake of food items (0.1
A
mSv /y). Further, taking into account the dietary pattern in
India and considering milk, meat, cereals and vegetables as
the important constituents of Indian diet and their daily con-
sumption by an average Indian, it has allowed only 0.013
mSv /y through milk and dairy products, Therefore, if the milk
B and dairy products containing the permissible level of Cs-137
are consumed in an unrestricted manner throughout the year _...
by an average Indian, the resulting .does for one full year
would only be 0.013 mSv, which is less than the dose permit-
ted by ICRP by a factor of more than 50. It is because of this ~
extra safety and caution, that the limits prescribed by AERB, ,
as given in the table at the end, are one of the lowest. Several '
c other countries, and agencies like FAO, on the other hand,
have allowed a higher portion of the permitted dose by ICRP
(upto full 1 mSv/year) to milk and dairy products, and conse-
quently their permissible limits are higher than those pres-
cribed by AERB.
D
10. The ·natural radiation dose varies from place to place in
India by a factor oMO, the average being around .7 mSv/year.
Even at the same place it can vary by a factor of 2 and more in
different seasons. The biological effects,·if any, due to the
consumption of food items containing permissible levels of _>...-
radionuclides will be insignificant and indistinguishable, from
those, if any, due to natural sources of radiation in the general
populadon.

11. The concept of permissible levels is not unique to radio-
nuclides. Such levels are prescribed by appropriate agencies \. _
F for other harmful substances as well, in the case of air and I
water pollutants and contaminants (microbial, chemical etc.).

12. Man-made radiosotopes like Cs-137 existed in milk and
other dairy and food products in measurable quantities due to
atmospheric testing of nuclear weapons, even prior to
G 'Chernoby 1 aceident. In India, a net-work of monitoring sta-
tions for such food items has been in operation at BARC since
mid-fifties. After the cessation of• large scale testing of ·).'
nuclear weapons in the atmosphere in 1962, as a result of the
partial test ban treaty, the levels of Cs-137 in India started
declining, after reaching their highest levels during 1964-65.
H China and France continued atmospheric testing of weapons
DR. S.S. WAGLE v. U.0.1. 127

t upto 70's, though on a much smaller scale, which gave rise to A
measurable levels of Cs-137 in Indian milk and dairy pro-
ducts. However, at no time the levels exceeded the permissi-
ble levels prescribed by AERB.

13. As a consequence of the above monitoring programme
B
pursued at BARC, very sensitive equipment and techniques
J- as well as sampling and monitoring experience has accumu-
' lated over the years. AERB, therefore, entrusted them with

-1- the task of measuring postehernoby 1 samples of imported
food items including milk and dairy products. Thus, in the
opinion of the Committee, measurement of butter oil samples
has been entrusted to the most competent agency in the c
'~- country.

14. The butter oil is normally used to make up the fat con-
tent of the reconstituted milk (6% for whole milk, for exam-
pie), and hence it will not form more than a few per cent
(maximum 6 per cent) of the milk to be distributed to the D
public. The level of radioactivity in reconstituted milk .will,
therefore, be diluted.by a .large .factor. Even if it is used for
. -
preparation of ghee as the end product, the le:vel of radio-
, activity in gh~e will not be significantly different, as both have
nearly same (around 99 per ,cent) fat _,content. Thus, no
mechanism is envisaged by which the radioactivity in the pro- E
duct meant for public distribution, using this butter oil,_can
get concentrated.
·'·
-_ .. ,-,
15. The petition makes a mention of sampling and ineasure-
'-ment.procedures for the butter oil consignment ·received by
·-~ IDC (now NDDB). IO this connection it is observe(! that three F
\
sets of samples from the consignment have been measured at
BARC. The first set comprises of 2 samples collected by IDC,
the second set of 10 samples collected and sent by the Quality
Control.. Officer of _Greater Bombay Milk Scheme. (GBMS)
and the third set of 20 samples copected jointly by the Quality
Control Officer of GBMS and the scientists '?f BARC. Only G
the first 2 samples showed very small levels of Cs-137 (2.9
~' Bq/kg and 1.3 Bq/kg), close to the detection levd and all the
rest showed below detection levels (detection level being 0.6
Bq/kg of Cs-137 activity). The fact that none of the packages
sampled in the three sets of samples collected have shown any
H
128 SUPREME COURT REPORTS [1988] 3 S.C.R.

A significant amount of radioactivity, with the most sensitive
equipment used in BARC, is a clear indication that it is most
unlikely that any of the unsampled packages are contamina-
ted with Cs-137 to the permissible limit set by AERB.

OPINION
"p.
On a consideration of all. the relevant facts, the unanimous opi-
D nion of !he Committee on the question referred to it is as follows:

1. The permissible level~ of radioactivity in n;ilk, dairy and other
food products fixed by the Atomic Energy Regulatory Bo2rd as
per its communication of August 27, 1987 have been arrived at
after due consideration of ICRP dose limits for the general
E
population.

2. The AERB has allowed more safety margin than other
countries, and international organisations like FAO and WHO,
in arriving at the levels fixed for milk, dairy and other food
F products. The !evels adopted by AERB are one of the lowest in
the world."

3. The consumption of milk, dairy and other food products,
having levels of man-made radionuclides below'the permissible
levels fixed by AERB, by all sections or' ·population, and
G
through-Out the year,'are safe and harmless.
