Varinder Kumar v. State of Himachal Pradesh
Background
The appellant was apprehended in 1995 carrying "charas" in gunny bags on his scooter. The trial court acquitted him citing non-compliance with search/seizure procedural safeguards, but the High Court reversed the acquittal and convicted him under the NDPS Act, sentencing him to 20 years. Before the Supreme Court, the appellant additionally argued, relying on the recent precedent in Mohan Lal v. State of Punjab, that his conviction was vitiated because the same police officer acted as both the informant and the investigating officer, which that precedent had held violates the right to a fair investigation.
Decision Breakdown
On the facts, the Court held the trial court's doubts about the seizure (missing seals, witness issues) were unfounded since the seals were duly produced and marked as exhibits, Section 50 of the NDPS Act did not apply since the contraband was recovered from bags and not the appellant's person, and the absence/hostility of independent witnesses did not vitiate the search given the surrounding facts. On the Mohan Lal argument, the Court held that while an investigation by the same person as the informant is indeed improper going forward, applying that rule retrospectively to invalidate convictions, trials, and investigations that had already concluded or were in progress before Mohan Lal was decided would cause disproportionate disruption to the criminal justice system. The Court therefore held Mohan Lal's rule applies only prospectively, and dismissed the appeal.
Lesson Learnt
When the Supreme Court lays down a new, stricter procedural safeguard in criminal investigations, it may apply that rule only going forward (prospectively) rather than retrospectively, to avoid unsettling convictions and prosecutions that were conducted when the law was unsettled.
