The document discusses different types of emergencies under the Indian Constitution. It outlines three types: national emergency (Article 352), state emergency (Article 356), and financial emergency (Article 360). For national emergency, the President can proclaim emergency if the security of India is threatened by war, external aggression, or armed rebellion. There have been three instances of national emergency in India. For state emergency (President's Rule), emergency can be imposed if a state government cannot function as per the Constitution. Judicial reviews have established some limitations on imposing President's Rule. Financial emergency can be imposed if India's financial stability is threatened.
