Doctrine of Necessity

The Doctrine of Necessity is a judicial and political doctrine invoked to legitimise actions—often by executives or courts—that would normally be unconstitutional or illegal, on the grounds that they are indispensable to the survival of the state, restoration of order, or continuity of government. It draws on the Roman maxim necessitas non habet legem ("necessity knows no law") and overlaps with concepts of state of emergency, raison d'état, and the common-law defence of necessity.

The doctrine became prominent in constitutional law through The State v. Dosso (Pakistan, 1958), in which Chief Justice Muhammad Munir validated the military coup of General Ayub Khan by citing Hans Kelsen's theory of revolutionary legality and the necessity principle. It was subsequently invoked—and sometimes repudiated—by courts in Pakistan, Nigeria, Grenada, Uganda, Cyprus, and Fiji to legitimise coups, dissolutions of parliament, or emergency rule. The Supreme Court of Cyprus famously applied it in Attorney-General v. Mustafa Ibrahim (1964) to keep state institutions functioning after the breakdown of the bicommunal constitution.

In international law and IR, the doctrine appears in a related but distinct form: Article 25 of the International Law Commission's 2001 Articles on Responsibility of States for Internationally Wrongful Acts permits a state to invoke necessity to preclude wrongfulness, but only under strict cumulative conditions—the act must be the only way to safeguard an essential interest against a grave and imminent peril, and must not seriously impair the interests of other states or the international community. The ICJ examined these conditions in the Gabčíkovo–Nagymaros Project case (Hungary/Slovakia, 1997).

Critics argue the doctrine is dangerously elastic, often retrofitting legality onto raw power. Pakistan's Supreme Court itself repudiated earlier necessity-based rulings in Asma Jilani v. Government of Punjab (1972) and again in 2009, signalling growing judicial discomfort with its abuse.
