Which article of the Indian Constitution allows for the imposition of President's Rule in states?

Article 356 is considered the most controversial article of the Indian Constitution as it provides for the imposition of President's Rule when a state government is unable to function according to constitutional provisions. This results in the dissolution of the state legislature and direct administration by the central government. The Supreme Court's 1994 SR Bommai case established that the imposition of President's Rule is subject to judicial review, addressing concerns about potential misuse of this power.
