Vidhan Sabha, also known as the State Legislative Assembly, is a legislative body in each of the states and certain union territories of India. In 22 states and 3 union territories, there is a unicameral legislature which is the sole legislative body. In 7 states, the legislative assembly is the lower house of their bicameral legislature with the upper house being the State Legislative Council. Each Member of the Legislative Assembly (MLA) is directly elected to serve 5-year terms by single-member constituencies. The Constitution of India states that a State Legislative Assembly must have no less than 60 and no more than 500 members, however, an exception may be granted via an Act of Parliament as is the case in the states of Goa, Sikkim, Mizoram, and the union territory of Puducherry which have fewer than 60 members.

The Vidhan Sabha is responsible for making laws and regulations for the state or union territory it represents. It has the power to create or abolish the State Legislative Council by passing a resolution to that effect by a majority of not less than two-thirds of the members present and voting. The Vidhan Sabha is also responsible for electing the Chief Minister of the state, who is the head of the state government.

In summary, Vidhan Sabha is the legislative assembly of each state and certain union territories of India. It is responsible for making laws and regulations for the state or union territory it represents, and electing the Chief Minister of the state.
