State of Bombay v. Kathi Kalu Oghad (1961)

Constitutional Law I · Rights of the Accused — Article 20

Facts.

In a criminal investigation the accused were required to give specimen handwriting, signatures and thumb impressions for comparison. They argued that this compelled them to be witnesses against themselves under Article 20(3).

Issue.

Does taking physical or specimen evidence from an accused amount to “being a witness against himself” and so violate Article 20(3)?

Held.

An eleven-judge Bench held that Article 20(3) bars only testimonial compulsion — being forced to communicate knowledge or make a statement. Giving fingerprints, handwriting or specimen signatures is physical evidence, not testimony, and may lawfully be compelled.

Why it matters.

It draws the enduring line between testimonial and physical evidence, the very distinction on which every self-incrimination problem turns.
