When the security of India or a part of it is threatened by war, external attack, or armed insurrection, the President can declare a national emergency under Article 352.In these instances, the President can declare a national emergency even before a war, external attack, or armed revolt occurs, if he believes there is an impending threat. The 38th Amendment Act of 1975 added this criterion. The term ‘External Emergency’ refers to when a national emergency is declared due to ‘war’ or ‘external attack’.It is described as an ‘Internal Emergency’ when it is declared on the grounds of ‘armed rebellion’. A declaration of national emergency could include the entire country or only a portion of it. The President could use the 42nd Amendment Act of 1976 to confine the scope of a National Emergency to a certain area of the country.The Constitution originally listed “internal disturbance” as the third cause for declaring a national emergency, but the phrase was too imprecise and had a broader connotation. As a result, the 44th Amendment Act of 1978 substituted the words “internal unrest” for “armed insurrection.”Only after obtaining a written recommendation from the Cabinet can the President declare a national emergency (added by 44th Constitutional Amendment Act of 1978). This means that the emergency will only be declared with the cabinet’s approval, not just on the Prime Minister’s recommendation (PM).The Supreme Court held in the Minerva Mills case (1980) that the declaration of a national emergency may be challenged in court on the grounds of malfeasance, or that the declaration is based on completely irrelevant and extraneous circumstances, or that it is ludicrous or perverse.
