Double jeopardy

Rare card · No. 70073

In jurisprudence, double jeopardy is a procedural defence (primarily in common law jurisdictions) that prevents an accused person from being tried again on the same or similar charges following an acquittal or conviction. Double jeopardy is a common concept in criminal law – in civil law, a similar concept is that of res judicata. A variation in common law countries is the peremptory plea, which may take the specific forms of autrefois acquit ('previously acquitted') or autrefois convict ('previously convicted'). These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem ('not twice against the same').
