Cognizable offence
An offence for which police may arrest without a warrant and investigate without a magistrate's order, as listed in the First Schedule of the criminal procedure code.

Liability of a master for torts committed by a servant in the course of employment; the control test and the course-of-employment test determine whether the relationship exists.
