military necessity.Int’l law. A principle of warfare allowing coercive force to achieve a desired end, as long as the force used is not more than is called for by the situation. • This principle dates from the Hague Convention on Laws and Customs of War on Land of October 18, 1907, which prohibits the destruction or seizure of enemy property “unless such destruction or seizure be imperatively demanded by the necessities of war.” [Cases: War and National Emergency 9. C.J.S. War and National Defense § 4.]
