Rights of the Accused — Article 20 — KSLU Constitutional Law Notes

Rights of the Accused — Article 20

The State prosecutes; the individual stands alone against its machinery. Article 20 is the Constitution levelling that fight — three ancient protections rolled into one article, and (unusually) rights that cannot be suspended even during an Emergency. Every crime-drama objection you have heard — “you can’t punish me under a law made after I acted”, “you can’t try me twice”, “you can’t make me confess” — is really Article 20.

Three shields for the accused

Article 20 gives every accused person three protections:

Protection against ex-post-facto law — Art 20(1). No one may be convicted for an act that was not an offence when it was done, and no one may be given a penalty greater than what the law allowed at that time. (You cannot be punished under a law that did not yet exist when you acted.)
Protection against double jeopardy — Art 20(2). No person shall be prosecuted and punished for the same offence more than once. The key: there must have been a previous prosecution AND punishment before a court or judicial tribunal. A departmental inquiry is not a “prosecution”, so departmental action followed by a criminal trial is not double jeopardy.
Protection against self-incrimination — Art 20(3). No person accused of an offence shall be compelled to be a witness against himself. Three ingredients: (i) he is accused of an offence, (ii) there is compulsion, and (iii) it makes him a witness against himself (i.e. testimonial).

A crucial limit on 20(3): it bars testimonial compulsion only. Physical evidence — fingerprints, specimen handwriting, blood samples — is not “being a witness”, so taking it does not violate Art 20(3) (State of Bombay v Kathi Kalu Oghad).

⚠️ DON’T CONFUSE — departmental penalty vs double jeopardy.

Being dismissed after a departmental inquiry and then criminally prosecuted is not double jeopardy — a departmental proceeding is not a “prosecution and punishment” before a court. Art 20(2) bites only where there was a prior judicial prosecution and punishment for the same offence.

🧩 WORKED EXAMPLE — fingerprints taken against the accused’s will

Facts. A magistrate orders that an accused’s specimen handwriting and fingerprints be taken against his will; he pleads Art 20(3).

Rule. Art 20(3) bars testimonial compulsion only; giving physical specimens is not “being a witness against oneself” (Kathi Kalu Oghad).

Apply. Fingerprints and handwriting specimens are physical, not testimonial; compelling them does not make the accused a witness against himself.

Conclusion. No violation of Art 20(3); the order is valid.

🧩 WORKED EXAMPLE — dismissed, then prosecuted

Facts. An officer is dismissed after a departmental inquiry under an anti-corruption rule, then criminally prosecuted for the same misconduct; he pleads double jeopardy.

Rule. Art 20(2) needs a prior prosecution and punishment before a court; a departmental inquiry is not a prosecution (S.A. Venkataraman v Union of India, 1954; and cf. Maqbool Hussain for customs confiscation).

Apply. The dismissal was departmental, not a judicial prosecution, so the later criminal trial is the first prosecution.

Conclusion. No double jeopardy; the criminal prosecution is valid.

Article 20(3), Constitution of India: “No person accused of any offence shall be compelled to be a witness against himself.”

In Simple Terms: the State cannot force you to give evidence that proves your own guilt — but it can still take physical proof like fingerprints.

Case Laws

Maqbool Hussain v State of Bombay (1953) — customs confiscation is not a “prosecution”; a later criminal trial is not double jeopardy.
[C-13] State of Bombay v Kathi Kalu Oghad (1961) — Art 20(3) bars testimonial compulsion only; fingerprints/handwriting specimens are allowed.
Nandini Satpathy v P.L. Dani (1978) — 20(3) protection extends to the police-interrogation stage, not just the trial.
Selvi v State of Karnataka (2010) — narco-analysis/polygraph without consent violates Art 20(3).
