noun
offense prosecutable without a formal complaint
Legal term for crimes that can be prosecuted even if the victim does not file a complaint, contrasting with 親告罪 (offenses requiring a complaint).
強盗は非親告罪なので、被害者が告訴しなくても起訴される。
Robbery is an offense prosecutable without a formal complaint, so the perpetrator can be indicted even if the victim does not press charges.
親告罪 requires a formal complaint from the victim for prosecution, whereas 非親告罪 does not.
Compound of 非 (non-) + 親告罪 (offense requiring a complaint). The exact historical derivation is uncertain; the term is a modern legal coinage.
