The pleas of autrefois acquit and autrefois convict are related to which principle?

The pleas autrefois acquit and autrefois convict assert an earlier acquittal or conviction and prevent a second trial in the circumstances prescribed by criminal procedure. They are related to double jeopardy, although Article 20(2) specifically requires prior prosecution and punishment and is narrower than the statutory protection.

Current law: For proceedings governed by BNSS from 1 July 2024, section 337 replaces CrPC section 300. Proceedings saved under BNSS section 531 continue under the former Code; the constitutional guarantee remains unchanged.
