• Under the 7th Schedule of the Constitution, ‘Police’ is under the State list, meaning individual states typically legislate and exercise control over this subject. In the arrangement in force at the district level, a ‘dual system’ of control exists, in which the Superintendent of Police (SP) has to work with the District Magistrate (DM) for supervising police administration.
• At the metropolitan level, many states have replaced the dual system with the commissionerate system, as it is supposed to allow for faster decision-making to solve complex urban-centric issues.
• In the commissionerate system, the Commissioner of Police (CP) is the head of a unified police command structure, is responsible for the force in the city, and is accountable to the state government. The office also has magisterial powers, including those related to regulation, control, and licensing.
