Dinesh Kumar vs. The State of Haryana
Background
The deceased left his village on a tractor to visit his sister and never returned; his body was recovered three days later from a canal, with a post-mortem confirming death by strangulation. The prosecution's case rested entirely on circumstantial evidence: that the appellant and a co-accused (who died during the appeal) were "last seen" with the deceased, plus recoveries of the deceased's watch and other items from the appellant's house. The trial court and the Punjab and Haryana High Court convicted the appellant of murder, kidnapping and robbery, relying heavily on his failure to explain his whereabouts.
Decision Breakdown
The Supreme Court found the medical evidence troubling: rigor mortis was still present in the limbs at the time of post-mortem, roughly 90 hours after the alleged time of death, an unusually long persistence that the prosecution never explained, casting doubt on the timeline connecting the "last seen" evidence to the death. The Court held that the lower courts had misapplied Section 106 of the Evidence Act (the rule that a fact especially within the accused's own knowledge must be explained by him): that provision only supplements the prosecution's case once its own evidence is otherwise solid, and cannot substitute for a weak chain of circumstantial evidence. Applying the settled five-fold test for circumstantial evidence cases, the Court found the chain of evidence incomplete and inconsistent with guilt beyond reasonable doubt, and allowed the appeal, setting aside the conviction and ordering the appellant's release.
Lesson Learnt
In a case built purely on circumstantial evidence, courts cannot lean on an accused's failure to explain himself (Section 106 of the Evidence Act) to fill gaps in a fundamentally weak or incomplete prosecution case: the burden always remains on the prosecution to prove guilt beyond reasonable doubt through a complete and unbroken chain of evidence.
