Generally, cognisable offence means an offence in which a police officer has the authority to make an arrest without a warrant and to start an investigation with or without the permission of a court. By contrast, in the case of a non-cognisable offence, a police officer does not have the authority to make an arrest without a warrant and an investigation cannot be initiated without a court order. The police can file a
first information report (FIR) only for cognisable offences. In cognisable cases police can make an investigation without prior permission of a magistrate. Cognisable cases are more serious than non-cognisable cases. Normally, serious offences are defined as cognisable and usually carry a sentence of 3 years or more. For a non-cognisable offence, a
community service register is registered instead of a first information report. == In India ==
