Double Jeopardy — Person Once Convicted or Acquitted Not to Be Tried for Same Offence
Double jeopardy — no second trial for same offence after acquittal or conviction by competent court
Legal Commentary
Explanation
Section 300 is the statutory double jeopardy protection. Reinforced by Article 20(2): 'No person shall be prosecuted and punished for the same offence more than once.' The provision: (1) bars re-trial after acquittal for same offence; (2) bars re-trial after conviction for same offence; (3) bars trial for different offence on same facts that could have been charged in original trial. Key limitations: only applies to trials before 'competent jurisdiction' courts; appeals are not new trials — they are continuation of same proceedings. The protection attaches to the 'same offence' — if new facts establish a genuinely separate offence, prosecution is not barred.
