These personal qualities, to which Huberus refers, are those impressed upon the individual by the law of the domicil; it is this that the author claims should be permitted to accompany the person into whatever country he might go, and should supersede the law of the place where he had taken up a temporary residence.
Now, as the domicil of Scott was in the State of Missouri, where he was a slave, and from whence he was taken by his master into Illinois for a temporary residence, according to the doctrine of Huberus, the law of his domicil would have accompanied him, and during his residence there he would remain in the same condition as in the State of Missouri. In order to have given effect to the rule, as claimed in the argument, it should have been first shown that a domicil had been acquired in the free State, which cannot be pretended upon the agreed facts in the case. But the true answer to the doctrine of Huberus is, that the rule, in any aspect in which it may be viewed, has no bearing upon either side of the question before us, even if conceded to the extent laid down by the author; for he admits that foreign Governments give effect to these laws of the domicil no further than they are consistent with their own laws, and not prejudicial to their own subjects; in other words, their force and effect depend upon the law of comity of the foreign Government. We should add, also, that this general rule of Huberus, referred to, has not been admitted in the practice of nations, nor is it sanctioned by the most approved jurists of international law. (Story Con., sec. 91, 96, 103, 104; 2 Kent. Com., p. 457, 458; 1 Burge Con. Laws, pp. 12, 127.)
We come now to the decision of this court in the case of Strader et al. v. Graham, (10 How., p. 2.) The case came up from the Court of Appeals, in the State of Kentucky. The question in the case was, whether certain slaves of Graham, a resident of Kentucky, who had been employed temporarily at several places in the State of Ohio, with their master's consent, and had returned to Kentucky into his service, had thereby become entitled to their freedom. The Court of Appeals held that they had not. The case was brought to this court under the twenty-fifth section of the judiciary act. This court held that it had no jurisdiction, for the reason, the question was one that belonged exclusively to the State of Kentucky. The Chief Justice, in delivering the opinion of the court, observed that "every State has an undoubted right to determine the status or domestic and social condition of the persons domiciled within its territory, except in so far as the powers of the States in this respect are restrained, or duties and obligations imposed upon them, by the Constitution of the United States. There is nothing in the Constitution of the United States, he observes, that can in any degree control the law of Kentucky upon this subject. And the condition of the negroes, therefore, as to freedom or slavery, after their return, depended altogether upon the laws of that State, and could not be influenced by the laws of Ohio. It was exclusively in the power of Kentucky to determine, for herself, whether their employment in another State should or should not make them free on their return."
It has been supposed, in the argument on the part of the plaintiff, that the eighth section of the act of Congress passed March 6, 1820, (3 St. at Large, p. 544,) which prohibited slavery north of thirty-six degrees thirty minutes, within which the plaintiff and his wife temporarily resided at Fort Snelling, possessed some superior virtue and effect, extra-territorially, and within the State of Missouri, beyond that of the laws of Illinois, or those of Ohio in the case of Strader et al. v. Graham. A similar ground was taken and urged upon the court in the case just mentioned, under the ordinance of 1787, which was enacted during the time of the Confederation, and re-enacted by Congress after the adoption of the Constitution, with some amendments adapting it to the new Government. (1 St. at Large, p. 50.)
In answer to this ground, the Chief Justice, in delivering the opinion of the court, observed: "The argument assumes that the six articles which that ordinance declares to be perpetual, are still in force in the States since formed within the territory, and admitted into the Union. If this proposition could be maintained, it would not alter the question; for the regulations of Congress, under the old Confederation or the present Constitution, for the government of a particular Territory, could have no force beyond its limits. It certainly could not restrict the power of the States, within their respective territories, nor in any manner interfere with their laws and institutions, nor give this court control over them.
"The ordinance in question, he observes, if still in force, could have no more operation than the laws of Ohio in the State of Kentucky, and could not influence the decision upon the rights of the master or the slaves in that State."
This view, thus authoritatively declared, furnishes a conclusive answer to the distinction attempted to be set up between the extra-territorial effect of a State law and the act of Congress in question.
It must be admitted that Congress possesses no power to regulate or abolish slavery within the States; and that, if this act had attempted any such legislation, it would have been a nullity. And yet the argument here, if there be any force in it, leads to the result, that effect may be given to such legislation; for it is only by giving the act of Congress operation within the State of Missouri, that it can have any effect upon the question between the parties. Having no such effect directly, it will be difficult to maintain, upon any consistent reasoning, that it can be made to operate indirectly upon the subject.
The argument, we think, in any aspect in which it may be viewed, is utterly destitute of support upon any principles of constitutional law, as, according to that, Congress has no power whatever over the subject of slavery within the State; and is also subversive of the established doctrine of international jurisprudence, as, according to that, it is an axiom that the laws of one Government have no force within the limits of another, or extra-territorially, except from the consent of the latter.
It is perhaps not unfit to notice, in this connection, that many of the most eminent statesmen and jurists of the country entertain the opinion that this provision of the act of Congress, even within the territory to which it relates, was not authorized by any power under the Constitution. The doctrine here contended for, not only upholds its validity in the territory, but claims for it effect beyond and within the limits of a sovereign State—an effect, as insisted, that displaces the laws of the State, and substitutes its own provisions in their place.
