In the context of Indian Constitutional law, President's Rule in a State under Article 356 of the Constitution of India is governed and interpreted by various judicial precedents. The landmark case that specifically addresses this issue is S.R. Bommai v. Union of India, AIR 1994 SC 1918.
Article 356 allows the President of India to take direct control of a state's machinery under certain conditions, often referred to as the imposition of President's Rule. The judgment in the case of S.R. Bommai v. Union of India is critical because it clarified circumstances under which such a rule could be applied and delimited the scope of misuse of Article 356.
