A reference to a few of the provisions of the Constitution will illustrate this proposition.

For example, no one, we presume, will contend that Congress can make any law in a Territory respecting the establishment of religion, or the free exercise thereof, or abridging the freedom of speech or of the press, or the right of the people of the Territory peacably to assemble, and to petition the Government for the redress of grievances.

Nor can Congress deny to the people the right to keep and bear arms, nor the right to trial by jury, nor compel any one to be a witness against himself in a criminal proceeding.

These powers, and others, in relation to rights of person, which it is not necessary here to enumerate, are, in express and positive terms, denied to the General Government; and the rights of private property have been guarded with equal care. Thus the rights of property are united with the rights of person, and placed on the same ground by the fifth amendment to the Constitution, which provides that no person shall be deprived of life, liberty, and property, without due process of law. And an act of Congress which deprives a citizen of the United States of his liberty or property, merely because he came himself or brought his property into a particular Territory of the United States, and who had committed no offense against the laws, could hardly be dignified with the name of due process of law.

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.

But in considering the question before us, it must be borne in mind that there is no law of nations standing between the people of the United States and their Government, and interfering with their relation to each other. The powers of the Government, and the rights of the citizen under it, are positive and practical regulations plainly written down. The people of the United States have delegated to it certain enumerated powers, and forbidden it to exercise others. It has no power over the person or property of a citizen but what the citizens of the United States have granted. And no laws or usages of other nations, or reasoning of statesmen or jurists upon the relations of master and slave, can enlarge the powers of the Government, or take from the citizens the rights they have reserved. And if the Constitution recognizes the right of property of the master in a slave, and makes no distinction between that description of property and other property owned by a citizen, no tribunal, acting under the authority of the United States, whether it be legislative, executive, or judicial, has a right to draw such a distinction, or deny to it the benefit of the provisions and guarantees which have been provided for the protection of private property against the encroachments of the Government.

Now, as we have already said in an earlier part of this opinion, upon a different point, the right of property in a slave is distinctly and expressly affirmed in the Constitution. The right to traffic in it, like an ordinary article of merchandise and property, was guaranteed to the citizens of the United States, in every State that might desire it, for twenty years. And the Government in express terms is pledged to protect it in all future time, if the slave escapes from his owner. This is done in plain words—too plain to be misunderstood. And no word can be found in the Constitution which gives Congress a greater power over slave-property, or which entitles property of that kind to less protection than property of any other description. The only power conferred is the power coupled with the duty of guarding and protecting the owner in his rights.

Upon these considerations, it is the opinion of the court that the act of Congress which prohibited a citizen from holding and owning property of this kind in the territory of the United States north of the line therein mentioned, is not warranted by the Constitution, and is therefore void; and that neither Dred Scott himself, nor any of his family, were made free by being carried into this territory; even if they had been carried there by the owner, with the intention of becoming a permanent resident.
