Examine the provisions under Art-356 of Indian Constitution.

Article 356 of the Indian Constitution deals with the provisions for the imposition of President's rule in a state. It gives the President of India the power to take over the administration of a state if the state government is unable to function according to the Constitution.

According to this article, if the President, on the basis of a report from the Governor of the state or otherwise, is satisfied that a situation has arisen in which the government of the state cannot be carried on in accordance with the provisions of the Constitution, he may issue a proclamation:

Directing that the powers of the legislature of the state shall be exercisable by or under the authority of Parliament.

Declaring that the powers of the Governor of the state, or such of them as may be specified in the proclamation, shall be exercisable by the President or by such person or persons as he may direct.

Dissolving the legislative assembly of the state.

The President's rule can be imposed for a maximum period of six months, after which it must be approved by both houses of Parliament. The President's rule can be extended for an additional six months if the circumstances warrant it, but it must be approved by Parliament every six months. The President's rule can be revoked at any time by the President.

It is worth noting that the imposition of President's rule is a measure of last resort and is used only in exceptional circumstances, when the state government is unable to function according to the Constitution. It is also subject to judicial review, and the Supreme Court of India has the power to declare it unconstitutional if it finds that it has been imposed improperly.
