TANEY, C.J. . .. And upon a full and careful consideration of the subject, the court is of the opinion that, upon the facts stated in the plea in abatement, Dred Scott was not a citizen of Missouri within the meaning of the Constitution of the United States, and not entitled as such to sue in its courts; and, consequently, that the Circuit Court had no jurisdiction of the case, and that the judgment on the plea in abatement is erroneous....

We proceed, therefore, to inquire whether the facts relied on by the plaintiff entitled him to his freedom....

In considering this part of the controversy, two questions arise: 1st. Was he, together with his family, free in Missouri by reason of the stay in the territory of the United States hereinbefore mentioned? And 2nd, If they were not, is Scott himself free by reason of his removal to Rock Island, in the State of Illinois, as stated in the above admissions?

We proceed to examine the first question.

The Act of Congress, upon which the plaintiff relief, the Missouri Compromise declares that slavery and in voluntary servitude, except as a punishment for crime, shall be forever prohibited in all that part of the territory ceded by France, under the name of Louisiana, which lies north of thirty-six degrees thirty minutes north latitude, and not included within the limits of Missouri. And the difficulty which meets us at the threshold of this part of the inquiry is, whether Congress was authorized to pass this law under any of the powers granted to it by the Constitution; for if the authority is not given by that instrument, it is the duty of this court to declare it void and inoperative, and incapable of conferring freedom upon any one who is held as a slave under the laws of any one of the States.

The counsel for the plaintiff has laid much stress upon that article in the Constitution which confers on Congress the power "to dispose of and make an needful rules and regulations respecting the territory or other property belonging to the United States;" but, in the judgment of the court, that provision has no bearing on the present controversy, and the power there given, whatever it may be, is confined, and was intended to be confined, to the territory which at that time belonged to, or was claimed by, the United States, and was within their boundaries as settled by the treaty with Great Britain, and can have no influence upon a territory afterwards acquired from a foreign Government. It was a special provision for a known and particular territory, and to meet a present emergency, and nothing more...

If this clause is construed to extend to territory acquired by the present Government from a foreign nation, outside of the limits of any charter from the British Government to a colony, it would be difficult to say, why it was deemed necessary to give the Government the power to sell any vacant lands belonging to the sovereignty which might be found within it; and if this was necessary, why the grant of this power should precede the power to legislate over it and establish a Government there; and still more difficult to say, why it was deemed necessary so specially and particularly to grant the power to make needful rules and regulations in relation to any personal or movable property it might acquire there. For the words, other property necessarily, by every known rule of interpretation, must mean property of a different description from territory or land. And the difficulty would perhaps be in- surmountable in endeavoring to account for the last member of the sentence, which provides that "nothing in this Constitution shall be so construed as to prejudice any claims of the United States or any particular State," or to say how any particular State could have claims in or to a territory ceded by a foreign Government, or to account for associating this provision with the preceding provisions of the clause, with which it would appear to have no connection....

But the power of Congress over the person or property of a citizen can never be a mere discretionary power under our Constitution and form of Government. The powers of the Government and the rights and privileges of the citizen are regulated and plainly defined by the Constitution itself. And when the Territory becomes a part of the United States, the Federal Government enters into possession in the character impressed upon it by those who created it. It enters upon it with its powers over the citizen strictly defined, and limited by the Constitution, from which it derives its own existence, and by virtue of which alone it continues to exist and act as a Government and sovereignty. It has no power of any kind beyond it; and it cannot, when it enters a Territory of the United States, put off its character, and assume discretionary or despotic powers which the Constitution has denied to it. It cannot create for itself a new character separated from the citizens of the United States, and the duties it owes them under the provisions of the Constitution. The Territory being a part of the United States, the Government and the citizen both enter it under the authority of the Constitution, with their respective rights defined and marked out; and the Federal Government can exercise no power over his person or property, beyond what that instrument confers, nor lawfully deny any right which it has reserved...

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.... An Act of Congress which deprives a person 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....

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 . .. 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 . .. 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.

. .. 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 [the Missouri compromise] 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...

Upon the whole, therefore, it is the judgment of this court, that it appears by the record before us that the plaintiff in error is not a citizen of Missouri, in the sense in which that word is used in the Constitution; and that the Circuit Court of the United States, for that reason, had no jurisdiction in the case, and could give no judgment in it.

Its judgment for the defendant must, consequently, be reversed, and a mandate issued directing the suit to be dismissed for want of jurisdiction.
