Nebh Raj v. State (Delhi Administration) And Another
Factual and Procedural Background
On 17 October 1970 a Food Inspector of the Delhi Municipal Corporation purchased a sample of “Dal Biji” from the appellant’s shop. One part of the sample was analysed by the Public Analyst, who reported on 27 October 1970 that the product was adulterated because it contained an unpermitted coal-tar dye. No further action was taken for about two years. A criminal complaint was filed only on 13 November 1972.
On 17 April 1973 the appellant applied to have another part of the sample sent to the Director, Central Food Laboratory (CFL), Calcutta. The CFL received the sample on 2 May 1973 and, by a report dated 26 October 1973, found the product adulterated because the vanaspati in it contained 42.2 % “free fatty acid as oleic acid” (permissible limit 0.25 %). The report also stated that no added coal-tar dyes were present.
The Metropolitan Magistrate, Delhi convicted the appellant under Section 16 read with Section 7 of the Prevention of Food Adulteration Act, 1954, sentencing him to six months’ rigorous imprisonment and a fine of ₹1,000. The conviction and sentence were affirmed by the Additional Sessions Judge, Delhi, and a revision was dismissed in limine by the Delhi High Court. The present appeal was heard by the Supreme Court of India.
Legal Issues Presented
- Whether a conviction for adulteration can be sustained when the Director, Central Food Laboratory analysed the sample nearly three years after it was taken, thereby raising a strong possibility that the free-fatty-acid content increased naturally during storage.
- Where the CFL report supersedes the Public Analyst’s report, does the unexplained prosecutorial delay shift or satisfy the burden on the accused to show that the sample deteriorated?
Arguments of the Parties
Appellant's Arguments
- The CFL analysis occurred almost three years after the sample was taken, allowing oxidation during storage to raise the free-fatty-acid content far above permissible limits.
- Because the prosecution delayed both the filing of the complaint and the forwarding of the sample, the resultant deterioration should exonerate the appellant.
No specific arguments of the prosecution were recorded in the opinion.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| State of Tamil Nadu v. S. Shunmugham Chettiar, (1980) 4 SCC 487 | A short interval (three months and five days) between sampling and CFL analysis is insufficient to presume deterioration of free-fatty-acid content. | Distinguished: unlike the three-month gap in that case, the nearly three-year gap here made deterioration so probable that the conviction could not stand. |
Court's Reasoning and Analysis
The Supreme Court began by noting that under the Prevention of Food Adulteration Act the CFL report supersedes that of the Public Analyst, so the prosecution’s case rested entirely on the CFL’s finding of 42.2 % free fatty acid. Ordinarily the burden of proving natural increase would lie on the accused, but the Court found that the extraordinary delay—approximately three years between sampling and analysis—“sufficiently discharged” that burden.
The Court relied on recognised scientific literature (Woodman’s “Food Analysis” and David Pearson’s “Chemical Analysis of Foods”) to establish that exposure to air, light, moisture, heat, and traces of metal inevitably increase free-fatty-acid content in stored oils and fats. Given this universally accepted chemical process, the Court held that the possibility of deterioration in the present case was not merely speculative but highly probable.
Comparing the case to State of Tamil Nadu v. S. Shunmugham Chettiar, the Court found the earlier decision inapposite because the delay there was only three months, whereas the present delay was so long that deterioration could not be ruled out. In effect, the prosecution’s own inaction created reasonable doubt as to whether the sample was adulterated when taken.
The Court also expressly criticised the authorities for instituting proceedings more than two years after receiving the Public Analyst’s report, calling such tardiness “inexcusable” because it can both harass accused persons and allow guilty parties to escape punishment.
Holding and Implications
APPEAL ALLOWED; CONVICTION AND SENTENCE SET ASIDE. The appellant’s bail bonds were discharged and any fine paid was ordered to be refunded.
Implications: The ruling underscores that unexplained prosecutorial delay in forwarding food samples for CFL analysis can fatally undermine convictions under the Prevention of Food Adulteration Act when chemical changes during storage are probable. Although the Court did not lay down a fixed time-limit, it signalled that long delays are unacceptable and may compel acquittal. No new legal doctrine was announced, but the decision serves as a caution against tardiness in food-adulteration prosecutions.
O. Chinnappa Reddy, J.— On October 17, 1970, a Food Inspector of the Delhi Municipal Corporation purchased a sample of Dal Biji from the shop of the appellant. One part of the sample was sent to the Public Analyst for analysis. The Public Analyst reported on October 27, 1970 that the sample was adulterated because of the presence of unpermitted coal tar dye. Thereafter there was a stalemate for about two years. A complaint was finally filed against the appellant on November 13, 1972. On April 17, 1973, the appellant moved the trial court to send another part of the sample for analysis to the Director of the Central Food Laboratory. This was accordingly done. A sample was received by the Director, Central Food Laboratory, Calcutta on May 2, 1973. After analysis the Director, Central Food Laboratory sent his ‘report on October 26, 1973. The precise date of analysis by the Director, Central Food Laboratory is not evident from the record. According to the report the sample was adulterated as the vanaspati used in the sample of Dal Biji contained 42.2 per cent of “free fatty acid as oleic acid” as against the permissible .25 per cent. The report also mentioned that “added coal tar dyes” were absent. The appellant was convicted by the Metropolitan Magistrate, Delhi, under Section 16 read with Section 7 of the Prevention of Food Adulteration Act, 1954, and sentenced to undergo rigorous imprisonment for a period of six months and to pay a fine of Rs 1000. The conviction and sentence were confirmed, on appeal, by the learned Additional Sessions Judge, Delhi. A revision preferred to the High Court of Delhi was dismissed in limine. One of the submissions made before the lower courts and the only submission now made before us is that the analysis by the Director, Central Food Laboratory, Calcutta was made nearly three years after the sample was taken. There was every possibility of the free fatty acid content of the sample having increased enormously by oxidation during storage. We are afraid that on the facts of this particular case we have to accept the submission made on behalf of the appellant. The report of the Director, Central Food Laboratory, Calcutta having superseded the report of the Public Analyst, the prosecution must stand or fall on the report of the Director, Central Food Laboratory. The report shows that there was 42.2 per cent of “free fatty acid as oleic acid” as against the permissible .25 per cent. Prima facie the sample was adulterated. The burden of proving that the free fatty acid content of the vanaspati had increased due to natural causes was upon the appellant. But, in the present case the burden is sufficiently discharged by the very passage of so long a time as three years from the date of taking the sample to the date of the analysis by the Director, Central Food Laboratory. That oxidation due to exposure to air has the effect of increasing the free fatty acid content of edible fats and oil cannot be disputed. Woodman in his Food Analysis, 4th Edn., p. 170, points out:
“When acted on by the oxygen of the air, especially in the presence of light and moisture, free fatty acids are liberated and altered with the accompanying production of various aldehydes and acids of lower molecular weight having a disagreeable odour and acrid taste, the fat or oil then being termed ‘rancid’.”
David Pearson in his Chemical Analysis of Foods — 7th Edn., p. 494, says:
“Fats undergo changes during storage which result in the production of an unpleasant taste and odour, which is commonly referred to as rancidity. Rancidity is brought about by the action of air or by micro-organisms. Oxidative rancidity is accelerated by exposure to heat and light, by moisture and by the presence of traces of certain metals (e.g copper, nickel, iron).... With most oils and fats the free acidity increases during storage....”
In State of Tamil Nadu v. S. Shunumugham Chettiar (1980) 4 SCC 487 which we decided a few weeks ago there was a time-gap of three months and five days between the taking of the sample and the analysis by the Director, Central Food Laboratory. The “free fatty acid as oleic acid” content of the gingelly oil was found by the Director, Central Food Laboratory to be 6.2 per cent as against the permissible 3 per cent. We held that the time-gap was not such as to justify an inference that the free fatty acid content of the gingelly oil had increased during storage. We therefore, convicted the accused in that case. But, in the present case the time-gap is so wide that we cannot but hold that the free fatty and content of the sample which was sent to the Director, Central Food Laboratory might have well increased during storage and that it is a possibility which is so probable as to be incapable of being ruled out. We, therefore, allow the appeal and set aside the conviction and sentence passed on the appellant. The bail bonds will stand discharged. The fine if paid will be refunded. We desire to add that there was no justification whatever for launching the prosecution more than two years after the sample was taken and after obtaining the report of the Public Analyst. To launch a prosecution at such a belated stage may result in causing harassment to the accused in some cases and may also result in genuine offenders escaping punishment. We are unable to see why sample cases under the Prevention of Food Adulteration Act should be launched so late. Tardiness in these matters is inexcusable.
