Shyamal Saha and Another v. State of West Bengal
Background
A man disappeared after allegedly crossing the Ganges with two acquaintances, and his body was found later. The trial court acquitted the acquaintances because important witnesses made substantial additions to their earlier accounts. The High Court reversed that decision, principally relying on the claim that the accused were last seen with the victim.
Decision Breakdown
The Supreme Court allowed the appeal and restored the acquittal. The High Court needed to identify a serious error in the trial court's reasoning, rather than simply adopt its own preferred view when acquittal was a reasonable possibility. Here the testimony underlying the supposed last-seen event was doubtful, leaving the first link in the circumstantial chain unproved. Medical evidence about the time of death did not identify the killers or repair that missing link.
Lesson Learnt
A last-seen theory cannot establish guilt when the evidence of that event itself is unreliable. An appellate court must respect a reasonable acquittal and give sound reasons before replacing it with a conviction.
