Civic administration :

Mumbai consists of two distinct regions: the city and the suburbs, which also form two separate districts of Maharashtra. The city region is also commonly referred to as the Island City. Mumbai, both island city and suburbs as a whole, is administered by the Brihanmumbai Municipal Corporation (BMC) (formerly the Bombay Municipal Corporation), with executive power vested in the Municipal Commissioner, who is an IAS officer appointed by the state government. The Corporation comprises 227 directly elected Councillors representing the twenty four municipal wards, five nominated Councillors, and a titular Mayor. The BMC is in charge of the civic and infrastructure needs of the metropolis. An Assistant Municipal Commissioner oversees each ward for administrative purposes. Almost all the state political parties field candidates in the elections for Councillors.

The Mumbai Metropolitan Region consists of 7 Municipal Corporations and 13 Municipal Councils. In addition to the BMC, it includes the Municipal Corporations of Thane, Kalyan-Dombivali, Navi Mumbai, Mira-Bhayandar, Bhiwandi-Nizampur and Ulhasnagar. Greater Mumbai forms two districts of Maharashtra, each under the jurisdiction of a District Collector. The Collectors are in charge of property records and revenue collection for the Central Government, and oversee the national elections held in the city.

The Mumbai Police is headed by a Police Commissioner, who is an IPS officer. The Mumbai Police comes under the state Home Ministry. The city is divided into seven police zones and seventeen traffic police zones, each headed by a Deputy Commissioner of Police. The Traffic Police is a semi-autonomous body under the Mumbai Police. The Mumbai Fire Brigade department is headed by the Chief Fire Officer, who is assisted by four Deputy Chief Fire Officers and six Divisional Officers.

Mumbai is the seat of the Bombay High Court, which exercises jurisdiction over the states of Maharashtra and Goa, and the Union Territories of Daman and Diu and Dadra and Nagar Haveli. Mumbai also has two lower courts, the Small Causes Court for civil matters, and the Sessions Court for criminal cases. Mumbai also has a special TADA (Terrorist and Disruptive Activities) court for people accused of conspiring and abetting acts of terrorism in the city.

The city elects six members to the Lok Sabha and thirty-four members to the Maharashtra Vidhan Sabha (State Assembly). Mumbai is headed by mayor Shubha Raul, Municipal Commissioner Jairaj Phatak, and Sheriff Indu Shahani.
