So, too, it will hardly be contended that Congress could by law quarter a soldier in a house in a Territory without the consent of the owner, in time of peace; nor in time of war, but in a manner prescribed by law. Nor could they by law forfeit the property of a citizen in a Territory who was convicted of treason, for a longer period than the life of the person convicted; nor take private property for public use without just compensation. The powers over person and property of which we speak are not only not granted to Congress, but are in express terms denied, and they are forbidden to exercise them. And this prohibition is not confined to the States, but the words are general, and extend to the whole territory over which the Constitution gives it power to legislate, including those portions of it remaining under Territorial Government, as well as that covered by States. It is a total absence of power everywhere within the dominion of the United States, and places the citizens of a Territory, so far as these rights are concerned, on the same footing with citizens of the States, and guards them as firmly and plainly against any inroads which the General Government might attempt, under the plea of implied or incidental powers. And if Congress itself cannot do this--if it is beyond the powers conferred on the Federal Government--it will be admitted, we presume, that it could not authorize a Territorial Government to exercise them. It could confer no power on any local Government, established by its authority, to violate the provisions of the Constitution. It seems, however, to be supposed, that there is a difference between property in a slave and other property, and that different rules may be applied to it in expounding the Constitution of the United States. And the laws and usages of nations, and the writings of eminent jurists upon the relation of master and slave and their mutual rights and duties, and the powers which Governments may exercise over it, have been dwelt upon in the argument.
