'that which is otherwise not lawful is made lawful by necessity', Henry de Bracton
Wikipedia defines the term Doctrine of Necessity as the basis of extra legal actions taken by state actors, which are designed to restore order and are found to be constitutional. Wikipedia states further that the doctrine originates from the writings of Henry de Bracton, a medieval jurist.
Clearly, the definition excludes non state actors. It does however empower arms of the state to restore order out of the chaos a country is in.
The most recent application of the Doctrine of Necessity, according to Wikipedia, was in February 2010 where the Nigerian National Assembly passed a resolution making the Vice President Acting President and Commander in Chief of the Armed forces. It was also used in 1985 by the Supreme Court of Granada to legitimize the existence of a lower court established when the Constitution had been suspended. The first time it was applied in modern times was in 1954, when the Governor General of Pakistan dissolved the Constituent Assembly and appointed a Council of Ministers because in he’s opinion the former did not represent the wishes of the people.
Why is it necessary to toss around this potent doctrine?
I believe the nation is currently in such disarray at the moment that some saner state actor(s) need(s) to restore order.
