State Government
(1) There shall be a Council of Ministers with the Chief Minister at the head to aid and advise the Governor, except where the Governor is required by the Constitution to act in his own discretion. (2) If a question arises whether a matter is one for the Governor's discretion, the Governor's decision on that is final, and cannot be challenged on the ground that they should or shouldn't have used discretion. (3) What advice Ministers gave the Governor cannot be inquired into by any court.
This mirrors Article 74 at the state level: real governing power rests with the elected Council of Ministers headed by the Chief Minister, not the Governor personally - except for a specific, limited set of situations where the Constitution requires the Governor to act using their own independent judgment ("discretion"), such as certain decisions about inviting someone to form a government.
This "discretion" carve-out is why a Governor's choice of which party leader to invite to form a government after a hung/unclear election result is sometimes controversial - it's one of the few areas where the Governor can act on their own judgment rather than simply following ministerial advice.
