As per case facts, the appellant, a manager at the Employee State Insurance Corporation, was accused of demanding a bribe to reduce an alleged outstanding ESI contribution from a bakery ... owner. A written complaint was made, a trap was arranged, and currency notes, treated with phenolphthalein powder, were recovered from the appellant's bag after he allegedly accepted the money. The trial court subsequently convicted him under the Prevention of Corruption Act. The appellant appealed, contending that the prosecution failed to establish a clear demand for illegal gratification, the sanction for prosecution was not properly proved, and witness testimonies were contradictory, rendering the trap doubtful. The central legal question was whether the prosecution had sufficiently proven the demand for illegal gratification, a fundamental requirement for conviction under the Prevention of Corruption Act, through either direct or circumstantial evidence. Finally, the High Court, citing various Supreme Court judgments, held that proof of demand is a sine qua non for such offenses. Upon reviewing the evidence, the Court found significant contradictions and unreliability in the complainant's and other witnesses' testimonies, indicating a failure to establish the demand for bribe. The Court also noted the absence of sufficient material to prove the alleged outstanding ESI dues or the appellant's specific role in their assessment. Consequently, the High Court determined that the prosecution could not prove its case beyond a reasonable doubt, particularly regarding the essential element of demand, and thus, the statutory presumption under the Act did not apply. The conviction and sentence were set aside, and the appellant was acquitted, receiving the benefit of doubt.
