Theory:

The Legislative Council is also known as the upper house of the State Legislature. It is a permanent body but can be abolished by passing a resolution in Parliament.
The Legislative Council's minimum strength must be 40, and the maximum strength must be one-third of the total members of the Legislative Assembly.
Example:
e.g. if the total number of legislative assembly members is 240, then the maximum number of Legislative Council should be 80.
The tenure of its members is six years. The Chairman elected by its members is the presiding officer, conducts the meetings and maintains the house's decorum. The Deputy Chairman will conduct the meetings in the absence of the Chairman. Chairman and Deputy Chairman are the legislative council members and are elected by the other members.
