Martial Law when some national emergency or crisis threatens public order in the United States, the comment is made that the President may ultimately resort to imposing martial law in order to preserve discipline and good behavior is the imposition of the highest-ranking military officer as the military governer or as the
head of the government, thus removing all power from the previous executive, legislative, and judicial branches of government.It is usually imposed temporarily when the government or civilian authorities fail to function effectively (e.g., maintain order and security, or provide essential services).
Martial law can be used by governments to enforce their rule over the public. Such incidents may occur when threatened by popular protest to suppress political opposition or to stabilize insurrections or perceived insurrections. Martial law may be declared in cases of major natural disasters; however, most countries use a different legal construct, such as a state of emergency.
Martial law has also been imposed during conflicts and in cases of occupations, where the absence of any other civil government provides for an unstable population.Typically, the imposition of martial law accompanies
curfews, the suspension of
civil law,
civil rights,
habeas corpus, and the application or extension of
military law or
military justice to civilians. Civilians defying martial law may be subjected to
military tribunal.
