Answer: The declaration of a state of emergency in the event of a war, external aggression, or armed rebellion is the subject of Article 352 of the Constitution. This situation is commonly referred to as a “National Emergency.”
In accordance with Article 352, the President of India has the authority to declare a state of national emergency whenever the safety of all or a portion of India is endangered as a result of a state of war, external aggression, or armed insurrection.
In addition, the president has the authority to declare a state of national emergency even before a war, act of external aggression, or armed insurrection has actually taken place, provided that he is convinced that there is an immediate threat.
