CODE.
§ 1. A place, district, or country, invested or occupied by an enemy, stands, in consequence of the occupation, under the Martial Law of the investing or invading army, whether any proclamation declaring Martial Law, or any public warning to the inhabitants, has been issued or not. Martial Law is the immediate and direct effect and consequence of occupation or conquest.
The presence of a hostile army proclaims its Martial Law.
§ 2. Martial Law does not cease during the hostile occupation, except by special proclamation, ordered by the commander in chief; or by special mention in the treaty of peace, concluding the war, when the occupation of a place or territory continues beyond the conclusion of peace, as one of the conditions of the same.
§ 3. Martial Law in a hostile country, consists in the suspension, by the occupying military authority, of the criminal and civil law, and of the domestic administration and government in the occupied place or territory, and in the substitution of military rule and force, for the same; as well as in the dictation of general laws—as far as military necessity requires this suspension, substitution, and dictation.
It is not unusual to proclaim that the administration of all civil and penal law shall continue, as in times of peace, unless specially interfered with by the military authority.
§ 4. Martial Law, although called law, does not consist in a body of rules of action. There is not even a distinct term for it in other languages.
Martial Law in a conquered or invaded country, or place, is temporary Military Absolutism, in the hands of commanders, who, therefore, must take care that it does not degenerate into arbitrary despotism. Martial Law is not the reckless use of military power by the highest or lowest in arms. Military oppression is not Martial Law.
