Doctrine of necessity

The doctrine of necessity is the basis on which extra-legal actions by state actors, which are designed to restore order, are found to be constitutional. It also includes the ability of a private person to violate a law without punishment where the violation of law was necessary to prevent even worse harm. The on which the doctrine is based originated in the writings of the medieval jurist, and similar justifications for this kind of extra-legal action have been advanced by more recent legal authorities, including.

In modern times, the doctrine was first used in a controversial 1954 judgment in which Pakistani Chief Justice validated the extra-constitutional use of emergency powers by,. In his judgment, the Chief Justice cited, 'that which is otherwise not lawful is made lawful by necessity', thereby providing the label that would come to be attached to the judgment and the doctrine that it was establishing.

The doctrine of necessity has since been applied in a number of countries, and in 2010 was invoked to justify extra-legal actions in.

Pakistan, 1954: First use
On 24 October 1954 the Governor-General of Pakistan,, dissolved the and appointed a new Council of Ministers on the grounds that the existing one no longer represented the people of Pakistan. argues that the real reason for the dissolution was because Mohammad objected to the constitution which the Assembly was about to adopt. The President of the Constituent Assembly,, appealed to the Chief Court of Sind at Karachi to restrain the new Council of Ministers from implementing the dissolution and to determine the validity of the appointment of the new Council under Section 223-A of the constitution.

In response, members of the new Council of Ministers appealed to the court saying that it had no jurisdiction to approve the request of the President to overturn the dissolution and appointments. They argued that Section 223-A of the constitution had never been validly enacted into the Constitution because it was never approved of by the Governor-General, and therefore anything submitted under it was invalid. The Chief Court of Sind ruled in favour of President Tamizuddin and held that the Governor-General's approval was not needed when the Constituent Assembly was acting only as a Constituent Assembly and not as the Federal Legislature. The Federation of Pakistan and the new Council of Ministers then appealed to the court, the appeal was heard in March 1955 (Federation of Pakistan v Maulvi Tamizuddin Khan).

In the appeal hearing under Chief Justice Muhammad Munir, the court decided that the Constituent Assembly functioned as the 'Legislature of the Domain' and that the Governor-General's assent was necessary for all legislation to become law. Therefore, the Chief Court of Sind had no jurisdiction to overturn the Governor General's dissolution and it was held as valid.

However, the ground of which the court found in favour of the Federation of Pakistan called into question the validity of all legislation passed by the Assembly, not to mention the unconstitutionality of the Assembly itself since 1950. To solve this problem, the Governor-General invoked Emergency Powers to retrospectively validate the Acts of the Constituent Assembly. An appeal was filed against the Governor-General for invoking emergency powers and the Chief Justice had to determine the constitutionality of invoking the Emergency Powers and whether the Governor-General could give his assent to legislation retroactively.

The Court held that in this case the Governor-General could not invoke emergency powers because in doing so he validated certain laws that had been invalid because he had not assented to them previously. Justice Munir also ruled that constitutional legislation could not be validated by the Governor General but had to be approved by the Legislature. The lack of a Constituent Assembly did not transfer the Legislature's powers over to the Governor-General.

The Court was referred to for an opinion. On 16 May 1955 it ruled:


 * 1) The Governor General in certain circumstances had the power to dissolve the Constituent Assembly.
 * 2) The Governor-General has during the interim period the power 'under the common law of civil or state necessity' of retrospectively validating the laws listed in the Schedule to the Emergency Powers ordinance.
 * 3)  The new Assembly (formed under the Constituent Convention Order 1955) would be valid and able to excerise all powers under the .

In his verdict, Munir declared it was necessary to go beyond the constitution to what he claimed was the Common Law, to general legal maxims, and to English historical precedent. He relied on maxim, 'that which is otherwise not lawful is made lawful by necessity', and the Roman law maxim urged by, 'the well-being of the people is the supreme law'.

Grenada, 1985: Second use
In a 1985 judgment, the Chief Justice of the High Court of invoked the doctrine of necessity to validate the legal existence of a court then trying for murder the persons who had conducted a coup against former leader. The court had been established under an unconstitutional "People's Law" following the overthrow of the country's constitution, which had subsequently been restored. The defendants argued that the court before which they were being tried had no legal existence under the restored constitution, and they were therefore being deprived of their constitutional right to a trial before a "Court established by law". The High Court acknowledged that the lower court "had come into existence in an unconstitutional manner", but "the doctrine of necessity validated its acts." On this basis, the murder trials were allowed to proceed.

Nigeria, 2010: Nigerian parliament creates an Acting President
A related (although non-judicial) use of the doctrine took place when, on 9 February 2010, the n National Assembly passed a resolution making Vice President the Acting President and Commander in Chief of the Armed Forces. Both chambers of the Assembly passed the resolution after President, who for 78 days had been in receiving medical treatment, was unable to formally empower the vice president to exercise full powers as acting president, as provided for in Section 145 of the country's constitution. No provision of the Nigerian constitution empowering the National Assembly to pass any such resolution, causing Senate President to assert that the Senate had been guided by the "doctrine of necessity" in arriving at its decision.

Private Parties
Necessity is a defense to violating a law where the violation was done in order to stop or prevent worse harm. For example, a person must have a license to operate a motor vehicle. However, if a person was requiring immediate medical attention and the only person who could drive them to the hospital did not have a license, it would be permissible for them to drive the sick person to the hospital.
