Your Voice Is Evidence, Not Testimony: Magistrates Can Direct Voice Samples From Accused and Witnesses Alike

Voice-based evidence — intercepted calls, ransom demands, bribe negotiations on tape — decides modern prosecutions, and comparison requires samples. Ritesh Sinha v. State of U.P. (2019) filled the old CrPC's gap by recognising a Magistrate's power to direct an accused to give samples; this case asked the next questions: does the power reach witnesses, and does compulsion offend Article 20(3)?

The Key Question Before the Court

Can a Magistrate compel voice samples from persons other than the accused — and does any such compulsion violate the privilege against self-incrimination?

The Fingerprint Logic of the Voice

The Court applied the settled distinction of Kathi Kalu Oghad: Article 20(3) protects a person from being compelled to be a witness against himself — from conveying personal knowledge through testimony. A voice sample conveys nothing of the kind: like fingerprints, specimen signatures or handwriting, it is identificatory material whose worth lies in comparison by experts, not in its communicative content. Compelling it is therefore constitutionally unobjectionable — for the accused, and a fortiori for witnesses, to whom the privilege does not extend at all.

From Judicial Gap-Filling to Statutory Power

The judgment knits the law's two eras together: the Ritesh Sinha power, exercised in the statute's silence, now has legislative form in Section 349 BNSS, which authorises a Magistrate to order specimen signatures, handwriting, finger impressions and voice samples — including, in defined circumstances, from persons not arrested. Magistrates may accordingly direct any person connected with the matter to furnish samples, the safeguards being judicial authorisation and relevance to the investigation.

What the Court Actually Held

• A Magistrate may direct any person — accused or witness — to furnish voice samples.
• A voice sample is physical, identificatory evidence; compelling it does not attract Article 20(3).
• The power, recognised in Ritesh Sinha, now stands codified in Section 349 BNSS and operates accordingly.

Why This Judgment Matters

• It completes the law of voice identification for the interception age — samples can be compelled wherever comparison is needed.
• Extending the power to witnesses closes the gap that let key voices on tape stay unverified.
• It harmonises the judge-made rule with the BNSS, giving investigators one clear statutory route.
• The testimonial/physical distinction it reinforces governs the next technologies too — from gait to biometric comparisons.

What Should Advocates Take Away From the Judgment?

For Defence Counsel

• Resist voice-sample orders on relevance and procedure — the judicial-authorisation requirement and the sample's chain of custody — not on Article 20(3), which is foreclosed.

For Investigators and Prosecutors

• Route every sample through a Section 349 BNSS order, including for witnesses; a properly authorised, properly preserved sample is now near-unchallengeable at trial.

Frequently Asked Questions

Because Article 20(3) bars compelled testimony — communication of personal knowledge. A voice sample, like a fingerprint, communicates nothing; it merely provides material for expert comparison.

Not when a Magistrate directs it — the power extends to any person connected with the investigation, and the privilege against self-incrimination does not shield witnesses from identificatory procedures.

Section 349 of the BNSS, 2023 — the codification of the power first recognised judicially in Ritesh Sinha (2019), as applied in this judgment.
