Municipal Corporations are established in big cities according to the provisions made in the Acts enacted by the State Legislatures. The Councillors of Municipal Corporations are elected for 5 years. The elected Councillors elect one of them as Mayor annually.
The 74th Constitutional Amendment has provided for reservation of not less than 1/3rd of the total seats for women. There is also a provision of reservation of seats for Scheduled Castes, Scheduled Tribes and other weaker sections in proportion to their population.
In the event of dissolution of Municipal Corporation, the elections are held within six months. There is an official post of Municipal Commissioner, who is the Chief Executive Officer and is appointed by the State government. In case of Union Territories like Delhi it is done by the Central government.
