State Government
(1) The Chief Minister is appointed by the Governor, other Ministers by the Governor on the CM's advice; Ministers hold office at the Governor's pleasure. Certain states must have a Minister for tribal welfare. (1A) The Council of Ministers (including the CM) cannot exceed 15% of the State Legislative Assembly's membership, with a floor of 12 Ministers. (1B) Anti-defection disqualification under the Tenth Schedule also bars Minister appointment for the relevant period. (2) The Council of Ministers is collectively responsible to the State's Legislative Assembly. (3)-(5) Ministers take oaths before the Governor; a non-legislature-member Minister ceases to be one after six consecutive months; salaries are fixed by the State Legislature by law.
This mirrors Article 75 at the state level, including the same 15%-of-the-House cap on Cabinet size (with a 12-Minister floor for smaller assemblies) and the same collective-responsibility principle - a state government falls if it loses the confidence of its Legislative Assembly, just as the Union government falls if it loses the Lok Sabha's confidence.
Just as at the Union level, a state government can be brought down by a no-confidence motion succeeding in the State Legislative Assembly - the entire Council of Ministers, not just the Chief Minister individually, stands or falls together.
