Kavita v. State of Tamil Nadu — Post-mortem evidence, unexplained inconsistency

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

The facts

The accused was prosecuted under Sections 302 and 309 of the Penal Code after she jumped into a well, having first thrown her two young children into it; an extra-judicial confession was also part of the evidence against her.

The Supreme Court reiterated that the value of an extra-judicial confession depends on the veracity of the witness to whom it was made, and that the witness need not reproduce the accused’s exact words.

Turning to the medical evidence, the Court found that the doctor who conducted the post-mortem examination could not clearly explain why the body of the son floated to the surface almost instantly while the body of the daughter sank completely into the water — an inconsistency the post-mortem evidence left unresolved.

Because this central medical detail remained unclear, the Supreme Court held that the prosecution’s version could not be safely accepted, and allowed the appeal.

Why this belongs in the Forensic Docket: When the post-mortem evidence cannot explain a basic physical detail of how the bodies were found, that gap in the science becomes a gap in the case — an unresolved medical inconsistency deserves the same scrutiny as a missing weapon or a botched identification.
