Thus far the discussion has related to martial rule as exercisable in time of peace, that is, in times when, to be sure, civil disorder prevails, but when war - public war - does not exist. We have now to speak of martial rule when this latter condition is present.

It has already been learned that in war the enemy, be he a foreign one, or a rebel to whom the status of belligerent has been given, has no legal rights which those opposed to him must respect.15

15 He has of course those rights which international law recognizes, but these are not of a constitutional, or, strictly speaking, of a legal nature. The property still persist, though subject, as in all other cases, to the exercise of the police powers of the State. Those who exercise these powers, though military in character, still remain liable for any abuse of their authority. The civil courts are not necessarily closed, nor are any of the private actions of individuals subject to restraint except in so far as the efficiency of public service may require.

When a civil contest becomes a public war, all persons living within limits declared to be hostile become ipso facto enemies, and subject to treatment as such. As the Supreme Court, in Ford v. Surget,16 say with reference to the Civil War: "The district of country declared by the constituted authorities, during the late Civil War, to be in insurrection against the government of the United States, was enemy territory, and all the people residing within such district were, according to public law, and for ail purposes connected with the prosecution of the war, liable to be treated by the United States, pending the war, and while they remained within the lines of insurrection, as enemies, without reference to their personal sentiments and dispositions."

Different conditions prevail, however, in loyal districts. In these the existence of war does not operate to destroy or suspend the civil rights of the inhabitants.

Upon the actual scene of war, there is no question but that, for the time being, the military authorities are supreme, and that these may do whatever may be necessary in order that the military operations which are being pursued may succeed. Here martial law becomes inextinguishable from military government. "When martial law is invoked in face of invasion or rebellion that rises to proportions of belligerency, it is war power pure and simple." 17 It is in this sense that Field defines martial law as "simply military authority exercised in accordance with the laws and usages of war," and the Supreme Court as "the law of necessity in the actual presence of war." 18

The necessities being great and extraordinary, the executive and administrative, that is to say, the military, action that will be justified is correspondingly extensive. But, the populace being loyal, and the territory domestic, private rights of person and rebel, though recognized as a belligerent, and, therefore, not entitled to claim from the government which he is resisting any of the rights created by its law, may, by that government, if it sees fit, be held responsible as a violator of its law.

Private property may be seized and appropriated to a public use without the consent of the owner, when the public necessity demands. This taking of private property is, however, the courts have declared, not an exercise of military power which gives to the owner no claim for compensation, but a taking for the public use which, under the provision of the Fifth Amendment, demands that compensation be made. The manner of taking may, however, be that of the police power, in that the urgency may not permit the ordinary proceedings for valuation and condemnation.19

In Mitchell v. Harmony20 Chief Justice Taney has stated the general principle governing the authority and responsibility of military officers in the following words:

"There are," he says, "occasions where private property may lawfully be taken possession of or destroyed to prevent it from falling into the hands of the public enemy, and also where a military officer charged with a particular duty may impress private property and take it for public use. Under these circumstances the government is bound to make full compensation to the owner; but the officer is not a trespasser. But in every such case the danger must be present or impending, and the necessity such as does not admit of delay or the intervention of the civil authority to provide the requisite means. It is impossible to define the particular circumstances in which the power may be lawfully exercised. Every case must depend on its own circumstances. It is the emergency that gives the right, and the emergency must be shown before the taking can be justified. In deciding upon this necessity, the state of facts as they appeared at the time will govern the decision, because the officer in command must act upon the information of others as well as his own observation. And if, with such information as he can obtain, there is reasonable ground for believing that the peril is immediate or the necessity urgent, he may do what the occasion seems to require, and the discovery that he was mistaken will not make him a wrongdoer. It is not enough to show that he exercised an honest judgment, and took the property to promote the public service, he must also prove what the nature of the emergency was, or what he had reasonable grounds to believe it to be; and it will then be for the court and jury to say whether it was so pressing as to justify an invasion of private right. Unless this is established, the defense must fail because it is very clear that the law will not permit private property to be taken merely to insure the success of an enterprise against a public enemy." . . . "It can never be maintained that a military officer can justify himself for doing an unlawful act, by producing the order of his superior. The order may palliate, but it cannot justify."

19 "Private property, the Constitution provides, shall not be taken for public use without just compensation. . . . Extraordinary and unforeseen occasions arise, however, beyond all doubt, in cases of extreme necessity in time of war or of immediate or impending danger, in which private property may be impressed into the public service, or may be seized and appropriated to the public use, or may even be destroyed without the consent of the owner. . . . Exigencies of this kind do arise in time of war or impending public danger, but it is the emergency, as was said by a great magistrate, that gives the right, and it is clear that the emergency must be shown to exist before the taking can be justified. Such a justification may be shown, and when shown, the rule is well settled that the officer taking private property for such a purpose, if the emergency is fully proved, is not a trespasser, and that the government is bound to make full compensation to the owner."
