I shall proceed to state the grounds upon which I have arrived at the conclusion, that the judgment of the court below should be affirmed. The suit was brought in the court below by the plaintiff, for the purpose of asserting his freedom, and that of Harriet, his wife, and two children.

The defendant plead, in abatement to the suit, that the cause of action, if any, accrued to the plaintiff out of the jurisdiction of the court, and exclusively within the jurisdiction of the courts of the State of Missouri; for, that the said plaintiff is not a citizen of the State of Missouri, as alleged in the declaration, because he is a negro of African descent; his ancestors were of pure African blood, and were brought into this country and sold as negro slaves.

To this plea the plaintiff demurred, and the defendant joined in demurrer. The court below sustained the demurrer, holding that the plea was insufficient in law to abate the suit.

The defendant then plead over in bar of the action:

1. The general issue. 2. That the plaintiff was a negro slave, the lawful property of the defendant. And 3. That Harriet, the wife of said plaintiff, and the two children, were the lawful slaves of the said defendant. Issue was taken upon these pleas, and the cause went down to trial before the court and jury, and an agreed state of facts was presented, upon which the trial proceeded, and resulted in a verdict for the defendant, under the instructions of the court.

The facts agreed upon were substantially as follows:

That in the year 1834, the plaintiff, Scott, was a negro slave of Dr. Emerson, who was a surgeon in the army of the United States; and in that year he took the plaintiff from the State of Missouri to the military post at Rock Island, in the State of Illinois, and held him there as a slave until the month of April or May, 1836. At this date, Dr. Emerson removed, with the plaintiff, from the Rock Island post to the military post at Fort Snelling, situate on the west bank of the Mississippi river, in the Territory of Upper Louisiana, and north of the latitude thirty-six degrees thirty minutes, and north of the State of Missouri. That he held the plaintiff in slavery, at Fort Snelling, from the last-mentioned date until the year 1838.

That in the year 1835, Harriet, mentioned in the declaration, was a negro slave of Major Taliaferro, who belonged to the army of the United States; and in that year he took her to Fort Snelling, already mentioned, and kept her there as a slave until the year 1836, and then sold and delivered her to Dr. Emerson, who held her in slavery, at Fort Snelling, until the year 1838. That in the year 1836, the plaintiff and Harriet

were married, at Fort Snelling, with the consent of their master. The two children, Eliza and Lizzie, are the fruit of this marriage. The first is about fourteen years of age, and was born on board the steamboat Gipsey, north of the State of Missouri, and upon the Mississippi river; the other, about seven years of age, was born in the State of Missouri, at the military post called Jefferson Barracks.

In 1838, Dr. Emerson removed the plaintiff, Harriet, and their daughter Eliza, from Fort Snelling to the State of Missouri, where they have ever since resided. And that, before the commencement of this suit, they were sold by the Doctor to Sandford, the defendant, who has claimed and held them as slaves ever since.

The agreed case also states that the plaintiff brought a suit for his freedom, in the Circuit Court of the State of Missouri, on which a judgment was rendered in his favor; but that, on a writ of error from the Supreme Court of the State, the judgment of the court below was reversed, and the cause remanded to the circuit for a new trial.

On closing the testimony in the court below, the counsel for the plaintiff prayed the court to instruct the jury, upon the agreed state of facts, that they ought to find for the plaintiff; when the court refused, and instructed them that, upon the facts, the law was with the defendant.

With respect to the plea in abatement, which went to the citizenship of the plaintiff, and his competency to bring a suit in the Federal courts, the common-law rule of pleading is, that upon a judgment against the plea on demurrer, and that the defendant answer over, and the defendant submits to the judgment, and pleads over to the merits, the plea in abatement is deemed to be waived, and is not afterwards to be regarded as a part of the record in deciding upon the rights of the parties. There is some question, however, whether this rule of pleading applies to the peculiar system and jurisdiction of the Federal courts. As, in these courts, if the facts appearing on the record show that the Circuit Court had no jurisdiction, its judgment will be reversed in the appellate court for that cause, and the case remanded with directions to be dismissed.

In the view we have taken of the case, it will not be necessary to pass upon this question, and we shall therefore proceed at once to an examination of the case upon its merits. The question upon the merits, in general terms, is, whether or not the removal of the plaintiff, who was a slave, with his master, from the State of Missouri to the State of Illinois, with a view to a temporary residence, and after such residence and

return to the slave State, such residence in the free State works an emancipation.

As appears from an agreed statement of facts, this question has been before the highest court of the State of Missouri, and a judgment rendered that this residence in the free State has no such effect; but, on the contrary, that his original condition continued unchanged.

The court below, the Circuit Court of the United States for Missouri, in which this suit was afterwards brought, followed the decision of the State court, and rendered a like judgment against the plaintiff.

The argument against these decisions is, that the laws of Illinois, forbidding slavery within her territory, had the effect to set the slave free while residing in that State, and to impress upon him the condition and status of a freeman; and that, by force of these laws, this status and condition accompanied him on his return to the slave State, and of consequence he could not be there held as a slave.

This question has been examined in the courts of several of the slaveholding States, and different opinions expressed and conclusions arrived at. We shall hereafter refer to some of them, and to the principles upon which they are founded. Our opinion is, that the question is one which belongs to each State to decide for itself, either by its Legislature or courts of justice; and hence, in respect to the case before us, to the State of Missouri— a question exclusively of Missouri law, and which, when determined by that State, it is the duty of the Federal courts to follow it. In other words, except in cases where the power is restrained by the Constitution of the United States, the law of the State is supreme over the subject of slavery within its jurisdiction.

As a practical illustration of the principle, we may refer to the legislation of the free States in abolishing slavery, and prohibiting its introduction into their territories. Confessedly, except as restrained by the Federal Constitution, they exercised, and rightfully, complete and absolute power over the subject. Upon what principle, then, can it be denied to the State of Missouri? The power flows from the sovereign character of the States of this Union; sovereign, not merely as respects the Federal Government—except as they have consented to its limitation—but sovereign as respects each other. Whether, therefore, the State of Missouri will recognise or give effect to the laws of Illinois within her territories on the subject of slavery, is a question for her to determine. Nor is there any Constitutional power in this Government that can rightfully control her.5

Every State or nation possesses an exclusive sovereignty and jurisdiction within her own territory; and, her laws affect and bind all property and persons residing within it. It may regulate the manner and circumstances under which property is held, and the condition, capacity, and state, of all persons therein; and, also, the remedy and modes of administering justice. And it is equally true, that no State or nation can affect or bind property out of its territory, or persons not residing within it. No State, therefore, can enact laws to operate beyond its own dominions, and, if it attempts to do so, it may be lawfully refused obedience. Such laws can have no inherent authority extra-territorially. This is the necessary result of the independence of distinct and separate sovereignties.

Now, it follows from these principles, that whatever force or effect the laws of one State or nation may have in the territories of another, must depend solely upon the laws and municipal regulations of the latter, upon its own jurisprudence and polity, and upon its own express or tacit consent.

Judge Story observes, in his
Conflict of Laws, (p. 24,)

Nations, from convenience and comity, and from mutual interest, and a sort of moral necessity to do justice, recognise and administer the laws of other countries. But, of the nature, extent, and utility, of them, respecting property, or the state and condition of persons within her territories, each nation judges for itself; and is never bound, even upon the ground of comity, to recognise them, if prejudicial to her own interests. The recognition is purely from comity, and not from any absolute or paramount obligation.

Judge Story again observes,
(398,)

And he adds, (See also
2 Kent Com., p. 45717;
13 Peters, 519, 58918.)

These principles fully establish, that it belongs to the sovereign

State of Missouri to determine by her laws the question of slavery within her jurisdiction, subject only to such limitations as may be found in the Federal Constitution; and, further, that the laws of other States of the Confederacy, whether enacted by their Legislatures or expounded by their courts, can have no operation within her territory, or affect rights growing out of her own laws on the subject. This is the necessary result of the independent and sovereign character of the State. The principle is not peculiar to the State of Missouri, but is equally applicable to each State belonging to the Confederacy. The laws of each have no extra-territorial operation within the jurisdiction of another, except such as may be voluntarily conceded by her laws or courts of justice. To the extent of such concession upon the rule of comity of nations, the foreign law may operate, as it then becomes a part of the municipal law of the State. When determined that the foreign law shall have effect, the municipal law of the State retires, and gives place to the foreign law.

In view of these principles, let us examine a little more closely the doctrine of those who maintain that the law of Missouri is not to govern the status and condition of the plaintiff. They insist that the removal and temporary residence with his master in Illinois, where slavery is inhibited, had the effect to set him free, and that the same effect is to be given to the law of Illinois, within the State of Missouri, after his return. Why was he set free in Illinois? Because the law of Missouri, under which he was held as a slave, had no operation by its own force extra-territorially; and the State of Illinois refused to recognise its effect within her limits, upon principles of comity, as a state of slavery was inconsistent with her laws, and contrary to her policy. But, how is the case different on the return of the plaintiff to the State of Missouri? Is she bound to recognise and enforce the law of Illinois? For, unless she is, the status and condition of the slave upon his return remains the same as originally existed. Has the law of Illinois any greater force within the jurisdiction of Missouri, than the laws of the latter within that of the former? Certainly not. They stand upon an equal footing. Neither has any force extra-territorially, except what may be voluntarily conceded to them.

It has been supposed, by the counsel for the plaintiff, that a rule laid down by Huberus had some bearing upon this question. Huberus observes that

(
De Confl. Leg., lib. 1, tit. 3, sec. 12;
4 Dallas, 375 n.19;
1 Story Con. Laws, pp. 59, 60.)

The application sought to be given to the rule was this: that as Dred Scott was free while residing in the State of Illinois, by the laws of that State, on his return to the State of Missouri he carried with him the personal qualities of freedom, and that the same effect must be given to his status there as in the former State. But the difficulty in the case is in the total misapplication of the rule.

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, 45820;
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. 221.) 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 act22. 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

It has been supposed, in the argument on the part of the plaintiff, that the eighth section of the act of Congress passed March6, 1820, (
3 St. at Large, p. 54423,) which prohibited slavery north of thirty-six degrees thirty miutes, 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. 5024.)

In answer to this ground, the Chief Justice, in delivering the opinion of the court, observed:

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.

The consequences of any such construction are apparent. If Congress possesses the power, under the Constitution, to abolish slavery in a Territory, it must necessarily possess the like power to establish it. It cannot be a one-sided power, as may suit the convenience or particular views of the advocates. It is a power, if it exists at all, over the whole subject; and then, upon the process of reasoning which seeks to extend its influence beyond the Territory, and within the limits of a State, if Congress should establish, instead of abolish, slavery, we do

not see but that, if a slave should be removed from the Territory into a free State, his status would accompany him, and continue, notwithstanding its laws against slavery. The laws of the free State, according to the argument, would be displaced, and the act of Congress, in its effect, be substituted in their place. We do not see how this conclusion could be avoided, if the construction against which we are contending should prevail. We are satisfied, however, it is unsound, and that the true answer to it is, that even conceding, for the purposes of the argument, that this provision of the act of Congress is valid within the Territory for which it was enacted, it can have no operation or effect beyond its limits, or within the jurisdiction of a State. It can neither displace its laws, nor change the status or condition of its inhabitants.

Our conclusion, therefore, is, upon this branch of the case, that the question involved is one depending solely upon the law of Missouri, and that the Federal court sitting in the State, and trying the case before us, was bound to follow it.

The remaining question for consideration is, What is the law of the State of Missouri on this subject? And it would be a sufficient answer to refer to the judgment of the highest court of the State in the very case, were it not due to that tribunal to state somewhat at large the course of decision and the principles involved, on account of some diversity of opinion in the cases. As we have already stated, this case was originally brought in the Circuit Court of the State, which resulted in a judgment for the plaintiff. The case was carried up to the Supreme Court for revision. That court reversed the judgment below, and remanded the cause to the circuit, for a new trial. In that state of the proceeding, a new suit was brought by the plaintiff in the Circuit Court of the United States, and tried upon the issues and agreed case before us, and a verdict and judgment for the defendant, that court following the decision of the Supreme Court of the State. The judgment of the Supreme Court is reported in the
15 Misso. R., p. 57625. The court placed the decision upon the temporary residence of the master with the slaves in the State and Territory to which they removed, and their return to the slave State; and upon the principles of international law, that foreign laws have no extra-territorial force, except such as the State within which they are sought to be enforced may see fit to extend to them, upon the doctrine of comity of nations.

This is the substance of the grounds of the decision.

The same question has been twice before that court since, and the same judgment given, (
15 Misso. R., 59526;
17 Ib., 43427.) It must be admitted, therefore, as the settled law of the State,

and, according to the decision in the case of Strader et al. v.Graham, is conclusive of the case in this court.

It is said, however, that the previous cases and course of decision in the State of Missouri on this subject were different, and that the courts had held the slave to be free on his return from a temporary residence in the free State. We do not see, were this to be admitted, that the circumstance would show that the settled course of decision, at the time this case was tried in the court below, was not to be considered the law of the State. Certainly, it must be, unless the first decision of a principle of law by a State court is to be permanent and irrevocable. The idea seems to be, that the courts of a State are not to change their opinions, or, if they do, the first decision is to be regarded by this court as the law of the State. It is certain, if this be so, in the case before us, it is an exception to the rule governing this court in all other cases. But what court has not changed its opinions? What judge has not changed his?

Waiving, however, this view, and turning to the decisions of the courts of Missouri, it will be found that there is no discrepancy between the earlier and the present cases upon this subject. There are some eight of them reported previous to the decision in the case before us, which was decided in 1852. The last of the earlier cases was decided in 1836. In each one of these, with two exceptions, the master or mistress removed into the free State with the slave, with a view to a permanent residence—in other words, to make that his or her domicil. And in several of the cases, this removal and permanent residence were relied on, as the ground of the decision in favor of the plaintiff. All these cases, therefore, are not necessarily in conflict with the decision in the case before us, but consistent with it. In one of the two excepted cases, the master had hired the slave in the State of Illinois from 1817 to 1825. In the other, the master was an officer in the army, and removed with his slave to the military post of Fort Snelling, and at Prairie du Chien, in Michigan, temporarily, while acting under the orders of his Government. It is conceded the decision in this case was departed from in the case before us, and in those that have followed it. But it is to be observed that these subsequent cases are in conformity with those in all the slave States bordering on the free—in Kentucky, (
2 Marsh., 47628;
5 B. Munroe, 17629;
9 Ib., 56530) —in Virginia, (
1 Rand., 1531;
1 Leigh, 17232;
10 Grattan, 49533)—in Maryland, (
4 Harris and McHenry, 29534,
32235,
32536.) In conformity, also, with the law of England on this subject, Ex parte Grace, (
2 Hagg. Adm., R., 9437,) and with the opinions of the

most eminent jurists of the country. (
Story's Confl., 396 a;
2 Kent Com., 258 n.38;
18 Pick., 19339, Chief Justice Shaw. See Corresp. between Lord Stowell and Judge Story,
1 vol. Life of Story, p. 552, 558.)

Lord Stowell, in communicating his opinion in the case of the slave Grace to Judge Story, states, in his letter, what the question was before him, namely:

He observed, having reference to the decision of Lord Mansfield in the case of Somersett; but the practice, he observed, And so Lord Stowell held in the case.

Judge Story, in his letter in reply, observes:

Again he observes:

We may remark, in this connection, that the case before the Maryland court, already referred to, and which was decided in 1799, presented the same question as that before Lord Stowell, and received a similar decision. This was nearly thirty years before the decision in that case, which was in 1828. The Court of Appeals observed, in deciding the Maryland case, that

And Luther Martin, one of the counsel in that case, stated, on the argument, that the question had been previously decided the same way in the case of slaves returning from a residence in Pennsylvania, where they had become free under her laws.

The State of Louisiana, whose courts had gone further in

holding the slave free on his return from a residence in a free State than the courts of her sister States, has settled the law, by an act of her Legislature, in conformity with the law of the court of Missouri in the case before us. (
Sess. Law, 1846.)

The case before Lord Stowell presented much stronger features for giving effect to the law of England in the case of the slave Grace than exists in the cases that have arisen in this country, for in that case the slave returned to a colony of England over which the Imperial Government exercised supreme authority. Yet, on the return of the slave to the colony, from a temporary residence in England, he held that the original condition of the slave attached. The question presented in cases arising here is as to the effect and operation to be given to the laws of a foreign State, on the return of the slave within an independent sovereignty.

Upon the whole, it must be admitted that the current of authority, both in England and in this country, is in accordance with the law as declared by the courts of Missouri in the case before us, and we think the court below was not only right, but bound to follow it.

Some question has been made as to the character of the residence in this case in the free State. But we regard the facts as set forth in the agreed case as decisive. The removal of Dr. Emerson from Missouri to the military posts was in the discharge of his duties as surgeon in the army, and under the orders of his Government. He was liable at any moment to be recalled, as he was in 1838, and ordered to another post. The same is also true as it respects Major Taliaferro. In such a case, the officer goes to his post for a temporary purpose, to remain there for an uncertain time, and not for the purpose of fixing his permanent abode. The question we think too plain to require argument. The case of the Attorney Generalv.Napier, (
6 Welsh, Hurtst. and Gordon Exch. Rep., 21740,) illustrates and applies the principle in the case of an officer of the English army.

A question has been alluded to, on the argument, namely: the right of the master with his slave of transit into or through a free State, on business or commercial pursuits, or in the exercise of a Federal right, or the discharge of a Federal duty, being a citizen of the United States, which is not before us. This question depends upon different considerations and principles from the one in hand, and turns upon the rights and privileges secured to a common citizen of the republic under the Constitution of the United States. When that question arises, we shall be prepared to decide it.

Our conclusion is, that the judgment of the court below should be affirmed.
