Cognizable and non-cognizable offences Cognizable offences are those
offences for which a police officer may arrest without a court-mandated
warrant in accordance with the first schedule of the code. For non-cognizable cases the police officer may arrest only after being duly authorized by a warrant. Non-cognizable offences are, generally, relatively less serious offences than cognizable ones. Cognizable offences reported under section 154 CrPC while non-cognizable offences reported under section 155 CrPC. For non-cognizable offences the Magistrate empowered to take cognizance under section 190 CrPC. Under section 156(3) CrPC the Magistrate is competent to direct the police to register the case, investigate the same and submit the
challan/report for cancellation.
