Sunil Rai @ Paua & Ors. v. Union Territory, Chandigarh — Bloodstain evidence without blood-group matching

Part of the Forensic Docket on Legal Desire Forensics — a case where forensic or identification evidence broke down on appeal.

The facts

Three accused were convicted of murder under Sections 302/34 IPC by the trial court, largely on circumstantial evidence and an extra-judicial confession, and the High Court affirmed the conviction.

The Supreme Court held that the first link in the chain — that the deceased had been seen being chased by the accused — was not established, and that the witness who claimed the main accused had tried to shield one person while implicating another could not be relied upon.

Crucially, the Court held that the recovery of a blood-stained jacket belonging to the main accused was of no evidentiary consequence, because his own blood sample had never been taken to ascertain his blood group and compare it against the stains on the jacket.

Without that comparison, the bloodstain evidence could not corroborate the prosecution’s case, and the appeal was allowed.

Why this belongs in the Forensic Docket: A blood-stained garment proves nothing on its own — without a blood-group comparison against the accused, it is just a stained piece of cloth, and the Supreme Court will say so plainly when investigators skip that step.
