Initially, the President’s Rule is imposed for a period of six months but it can be extended upto a maximum period of three years. During this emergency, the President can suspend or dissolve the State Legislative Assembly. The President can himself assume all or any of the functions of the State. He may vest all or any of those functions in the Governor or any other executive authority.
