The Calcutta High Court has delivered a significant ruling reinforcing that convictions under the Essential Commodities Act cannot rest on speculative or unscientific measurements. In a case involving alleged stock shortages of high-speed diesel oil, the Court emphasized that the prosecution must establish guilt beyond reasonable doubt through reliable, methodical evidence - not on the basis of improvised tools or inconsistent testimony.
Background & Facts
The Dispute
The appellant, Bidhi Chand Chawrasia, was convicted under Section 7(1)(a)(ii) of the Essential Commodities Act for allegedly maintaining an unreported stock of 279 litres of high-speed diesel oil (HSD) at his service station in Dankuni. The prosecution alleged that during a raid on November 22, 1990, officials from the Department of Explosives and Boilers (DEB) discovered a wooden board stating "Tail Nahi Hai" (No Oil Available) and measured a shortage in the underground tanks. A separate barrel containing 100 litres of HSD was also seized. The appellant was not present during the raid; his employee, Anil Kumar Mishra, was arrested on-site.
Procedural History
- November 22, 1990: DEB officials conducted raid at Chawrasia Service Station
- December 18, 1992: Special Court convicted appellant and sentenced him to six months’ imprisonment and a ₹2,000 fine
- 1993: Criminal appeal filed under Section 374(2) CrPC challenging conviction
- February 6, 2026: Calcutta High Court allowed appeal and set aside conviction
Relief Sought
The appellant sought quashing of the conviction on grounds of flawed evidence, hostile witnesses, improper measurement techniques, and failure to prove possession or intent. He also challenged the non-joinder of his partnership firm and the absence of a valid license production record.
The Legal Issue
The central question was whether the prosecution proved beyond reasonable doubt that the appellant violated Paragraph 3(2) of the West Bengal Declaration of Stocks and Prices of Essential Commodities Order, 1977, given the absence of scientific stock measurement, hostile witnesses, and contradictory evidence regarding the display of the stock and price board.
Arguments Presented
For the Appellant
The learned Amicus Curiae contended that the measurement of HSD in the underground tanks was conducted using only a wooden stick, without accounting for the tank’s sloping base - a fact admitted by all witnesses. No measurement chart existed, and the officials lacked technical knowledge of tank geometry. The prosecution failed to prove that the board stating "No Oil Available" was displayed at the time of the raid, as it was removable and later found stored in an almirah. Two key prosecution witnesses, including the constable who accompanied the raid, were declared hostile. The license for HSD sales, though claimed to be with the District Magistrate’s office, was never corroborated by any receipt or official record.
For the Respondent
The State argued that the prosecution had established the case beyond reasonable doubt through seven witnesses, physical seizure of stock and documents, and the admission of the appellant as the main partner. It relied on the Special Court’s finding that the opening stock in registers matched the physical count, and the shortage of 279 litres was sufficient to infer violation. The State maintained that the hostile nature of some witnesses did not invalidate the entire case, particularly the testimony of the investigating officer and the scientific report on the seized sample.
The Court's Analysis
The Court undertook a meticulous review of the evidence and found the prosecution’s case fundamentally flawed. The measurement of oil in the underground tank, which formed the core of the allegation, was conducted without any calibrated instrument or scientific methodology. P.W.1, the DEB officer, admitted he had no knowledge of the tank’s diameter, slope, or volume calibration. The use of a stick to measure depth, without taking readings from both ends of the sloping tank, rendered the calculation inherently unreliable.
"The quantity that was decided was not on the basis of a robust scientific mechanism, but mostly on primary measurement made with a stick."
The Court further noted that the board allegedly displaying "No Oil Available" was found stored in an almirah, not on display, and its presence during the raid was uncorroborated. The hostile testimony of multiple eyewitnesses - including the constable who claimed to have arrested the appellant - undermined the credibility of the entire raid narrative. The prosecution also failed to establish that the appellant, who was absent during the raid, had actual control over the stock or the board. The non-joinder of the partnership firm and the absence of any proof regarding the license’s renewal status further weakened the case.
The Court held that the burden of proving violation under the Essential Commodities Act lies squarely on the prosecution, and where the foundational evidence is speculative and the witnesses unreliable, conviction cannot stand. The Special Court’s reliance on a single officer’s unverified measurement, despite the admission of technical inadequacy, amounted to a misapplication of the standard of proof.
The Verdict
The appellant won. The Calcutta High Court set aside the conviction and sentence, holding that the prosecution failed to prove the alleged violation beyond reasonable doubt due to unscientific measurement, hostile witnesses, and lack of corroborative evidence regarding the display of the stock and price board. The Court recorded appreciation for the Amicus Curiae’s assistance.
What This Means For Similar Cases
Scientific Measurement Is Mandatory
- Practitioners must challenge any prosecution relying on visual or stick-based measurements of storage tanks without calibration charts or technical expertise
- In Essential Commodities Act cases, courts will demand scientifically verifiable methods for stock quantification
- Expert testimony on tank geometry and evaporation loss must be sought where volume discrepancies are alleged
Hostile Witnesses Invalidate Core Testimony
- When multiple eyewitnesses to a raid turn hostile, especially those involved in measurement or arrest, the prosecution’s case collapses unless independently corroborated
- Courts will not sustain convictions based on the testimony of a single official when others recant or contradict
- Defence counsel should aggressively seek declarations of hostility to undermine the prosecution’s narrative
Display of Stock Board Must Be Proven, Not Assumed
- Mere seizure of a board does not prove it was displayed at the relevant time
- Prosecution must establish continuous and conspicuous display as mandated under Paragraph 3(2)
- Absence of corroborative evidence (e.g., photographs, third-party sightings) renders display allegations speculative
