Jarnail Singh v. State of Punjab — NDPS chain of custody, chemical examiner

Part of the Forensic Docket on Legal Desire Forensics — a conviction confirmed through final appeal, kept here as a method-of-crime record.

The facts

The case concerned the scope of Section 50 of the Narcotic Drugs and Psychotropic Substances Act, 1985, which the Supreme Court held applies only where the drug or narcotic is recovered as a consequence of a body search of the accused, and not where it is recovered from a container.

On the facts, opium had been seized from the accused, and there was a gap of twelve days between the seizure and the sending of the sample to the Chemical Examiner.

The Court held that this delay was not fatal to the prosecution’s case, and found no infirmity in the chain of custody (‘link evidence’) connecting the seized sample to the chemical examiner’s report.

The conviction was upheld.

Status: conviction upheld through final appeal.

Why this belongs in the Forensic Docket: A twelve-day gap before a narcotics sample reaches the chemical examiner will not, by itself, sink a prosecution — but only because the chain of custody was otherwise unbroken, which is exactly the kind of documentation an examiner must be able to show.
