In a parliamentary form of government the executive, headed by Chief Minister, and the legislature are supposed to work in close co-operation with one other.
As leader of the House he makes all policy statements in the House and whenever he feels his cabinet colleagues are not in a position to satisfy the House, he comes forward to help them. He defines government policies and programmes in the House and faces the opposition.
He communicates the views of the House to the Governor and as such he acts as a channel between the two. He decides for all practical purposes the agenda of the House. But in respect of legislature his most important power is that of the dissolution of the House.
At any time the Chief Minister can advise the Governor that the Vidhan sabha be dissolved, though the latter isn’t bound by that, but usually such an advice is accepted.
