number of states having bicameral legislature in india
Bicameralism Seven Indian States, Andhra Pradesh, Telangana, Bihar, Jammu-Kashmir, Karnataka, Maharashtra and Uttar Pradesh, have bicameral Legislatures, these are called legislative councils (Vidhan Parishad), one third of whom are elected every two years, there are graduate constituencies (members elected exclusively by graduates), teachers constituencies (members elected exclusively by teachers), municipal constituencies (members elected exclusively by Mayors and council members of the city Governments). From 1956 to 1958 the Andhra Pradesh Legislature was unicameral. In 1958, when the Legislative Council was formed, it became bicameral until 1 June 1985 when it was abolished. This continued until March 2007 when the Legislative Council was reestablished and elections were held for its seats. Since then the Andhra Pradesh Legislature has become once again bicameral. In Tamil Nadu, a resolution was passed on 14 May 1986 and the Legislative Council was dissolved on 1 November 1986. Again on 12 April 2010, a resolution was passed to bring it back bicameral, but became unsuccessful in 2011.
