Kirpal Singh vs. The State of Punjab
Background
In November 1997, Balwinder Singh was fatally attacked at night in his home in Punjab, and his wife Sharan Kaur, the main eyewitness, was also injured. She named the appellant, Kirpal Singh, as one of two attackers but did not initially name a second man, Kulwinder Singh, whom she only implicated later through separate complaints alleging a biased police investigation. The trial court convicted Kirpal Singh (while acquitting Kulwinder Singh) and the Punjab and Haryana High Court upheld this in 2008, over a decade before this Supreme Court appeal was finally decided in 2024.
Decision Breakdown
The Supreme Court found the evidence of Sharan Kaur and her son, the two central prosecution witnesses, to be riddled with contradictions and improbabilities: their claim to have carried the fatally injured/dead victim to two separate hospitals before returning home (bypassing a police station on the way) was contradicted by the treating doctor's own records; the alleged motive (business jealousy) was vague and uncorroborated; and the witnesses' credibility was further undermined by their own petitions alleging a "tainted" investigation, later contradicted under cross-examination. No weapon was recovered, and independent police inquiries had concluded the case against the accused was false. Applying the principle that a conviction cannot rest on "wholly unreliable" testimony lacking corroboration, the Court acquitted Kirpal Singh, who had already spent years on bail.
Lesson Learnt
Even a first informant's direct testimony cannot sustain a conviction if it is riddled with material contradictions and unnatural conduct that independent evidence (like hospital records) actively contradicts. Courts require corroboration when witness testimony is not "wholly reliable."
