The decision of Lord Mansfield was, "that so high an act of dominion" as the master exercises over his slave, in sending him abroad for sale, could not be exercised in England under the American laws, and contrary to the spirit of their own.

The decision of Lord Stowell is, that the authority of the English laws terminated when the slave departed from England. That the laws of England were not imported into Antigua, with the slave, upon her return, and that the colonial forum had no warrant for applying a foreign code to dissolve relations which had existed between persons belonging to that island, and which were legal according to its own system. There is no distinguishable difference between the case before us and that determined in the admiralty of Great Britain.

The complaint here, in my opinion, amounts to this: that the judicial tribunals of Missouri have not denounced as odious the Constitution and laws under which they are organized, and have not superseded them on their own private authority, for the purpose of applying the laws of Illinois, or those passed by Congress for Minnesota, in their stead. The eighth section of the act of Congress of the 6th of March, 1820, (3 Statutes at Large, 545,) entitled, "An act to authorize the people of Missouri to form a State Government," &c., &c., is referred to, as affording the authority to this court to pronounce the sentence which the Supreme Court of Missouri felt themselves constrained to refuse. That section of the act prohibits slavery in the district of country west of the Mississippi, north of thirty-six degrees thirty minutes north latitude, which belonged to the ancient province of Louisiana, not included in Missouri.

It is a settled doctrine of this court, that the Federal Government can exercise no power over the subject of slavery within the States, nor control the intermigration of slaves, other than fugitives, among the States. Nor can that Government affect the duration of slavery within the States, other than by a legislation over the foreign slave trade. The power of Congress to adopt the section of the act above cited must therefore depend upon some condition of the Territories which distinguishes them from States, and subjects them to a control more extended. The third section of the fourth article of the Constitution is referred to as the only and all-sufficient grant to support this claim. It is, that "new States may be admitted by the Congress to this Union; but no new State shall be formed or erected within the jurisdiction of any other State, nor any State be formed by the junction of two or more States, or parts of States, without the consent of the Legislatures of the States concerned, as well as of the Congress. The Congress shall have power to dispose of and make all needful rules and regulations respecting the territory or other property belonging to the United States; and nothing in this Constitution shall be so construed as to prejudice any claims of the United States, or of any particular State."

It is conceded, in the decisions of this court, that Congress may secure the rights of the United States in the public domain, provide for the sale or lease of any part of it, and establish the validity of the titles of the purchasers, and may organize Territorial Governments, with powers of legislation. (3 How., 212; 12 How., 1; 1 Pet., 511; 13 P., 436; 16 H., 164.)

But the recognition of a plenary power in Congress to dispose of the public domain, or to organize a Government over it, does not imply a corresponding authority to determine the internal polity, or to adjust the domestic relations, or the persons who may lawfully inhabit the territory in which it is situated. A supreme power to make needful rules respecting the public domain, and a similar power of framing laws to operate upon persons and things within the territorial limits where it lies, are distinguished by broad lines of demarcation in American history. This court has assisted us to define them. In Johnson v. McIntosh, (8 Wheat., 595—543,) [Transcriber's Note: modern citation form is 8 Wheat. 543, 595] they say: "According to the theory of the British Constitution, all vacant lands are vested in the Crown; and the exclusive power to grant them is admitted to reside in the Crown, as a branch of the royal prerogative.

"All the lands we hold were originally granted by the Crown, and the establishment of a royal Government has never been considered as impairing its right to grant lands within the chartered limits of such colony."

And the British Parliament did claim a supremacy of legislation coextensive with the absoluteness of the dominion of the sovereign over the Crown lands. The American doctrine, to the contrary, is embodied in two brief resolutions of the people of Pennsylvania, in 1774: 1st. "That the inhabitants of these colonies are entitled to the same rights and liberties, within the colonies, that the subjects born in England are entitled within the realm." 2d. "That the power assumed by Parliament to bind the people of these colonies by statutes, in all cases whatever, is unconstitutional, and therefore the source of these unhappy difficulties." The Congress of 1774, in their statement of rights and grievances, affirm "a free and exclusive power of legislation" in their several Provincial Legislatures, "in all cases of taxation and internal polity, subject only to the negative of their sovereign, in such manner as has been heretofore used and accustomed." (1 Jour. Cong., 32.)

The unanimous consent of the people of the colonies, then, to the power of their sovereign, "to dispose of and make all needful rules and regulations respecting the territory" of the Crown, in 1774, was deemed by them as entirely consistent with opposition, remonstrance, the renunciation of allegiance, and proclamation of civil war, in preference to submission to his claim of supreme power in the territories.

I pass now to the evidence afforded during the Revolution and Confederation. The American Revolution was not a social revolution. It did not alter the domestic condition or capacity of persons within the colonies, nor was it designed to disturb the domestic relations existing among them. It was a political revolution, by which thirteen dependent colonies became thirteen independent States. "The Declaration of Independence was not," says Justice Chase, "a declaration that the United Colonies jointly, in a collective capacity, were independent States, &c., &c., &c., but that each of them was a sovereign and independent State; that is, that each of them had a right to govern itself by its own authority and its own laws, without any control from any other power on earth." (3 Dall., 199; 4 Cr., 212.)

These sovereign and independent States, being united as a Confederation, by various public acts of cession, became jointly interested in territory, and concerned to dispose of and make all needful rules and regulations respecting it. It is a conclusion not open to discussion in this court, "that there was no territory within the (original) United States, that was claimed by them in any other right than that of some of the confederate States." (Harcourt v. Gaillord, 12 Wh., 523.) "The question whether the vacant lands within the United States," says Chief Justice Marshall, "became joint property, or belonged to the separate States, was a momentous question, which threatened to shake the American Confederacy to its foundations. This important and dangerous question has been compromised, and the compromise is not now to be contested." (6 C.R., 87.)

The cessions of the States to the Confederation were made on the condition that the territory ceded should be laid out and formed into distinct republican States, which should be admitted as members to the Federal Union, having the same rights of sovereignty, freedom, and independence, as the other States. The first effort to fulfil this trust was made in 1785, by the offer of a charter or compact to the inhabitants who might come to occupy the land.

Those inhabitants were to form for themselves temporary State Governments, founded on the Constitutions of any of the States, but to be alterable at the will of their Legislature; and permanent Governments were to succeed these, whenever the population became sufficiently numerous to authorize the State to enter the Confederacy; and Congress assumed to obtain powers from the States to facilitate this object. Neither in the deeds of cession of the States, nor in this compact, was a sovereign power for Congress to govern the Territories asserted. Congress retained power, by this act, "to dispose of and to make rules and regulations respecting the public domain," but submitted to the people to organize a Government harmonious with those of the confederate States.

The next stage in the progress of colonial government was the adoption of the ordinance of 1787, by eight States, in which the plan of a Territorial Government, established by act of Congress, is first seen. This was adopted while the Federal Convention to form the Constitution was sitting. The plan placed the Government in the hands of a Governor, Secretary, and Judges, appointed by Congress, and conferred power on them to select suitable laws from the codes of the States, until the population should equal 5,000. A Legislative Council, elected by the people, was then to be admitted to a share of the legislative authority, under the supervision of Congress; and States were to be formed whenever the number of the population should authorize the measure.

This ordinance was addressed to the inhabitants as a fundamental compact, and six of its articles define the conditions to be observed in their Constitution and laws. These conditions were designed to fulfil the trust in the agreements of cession, that the States to be formed of the ceded Territories should be "distinct republican States." This ordinance was submitted to Virginia in 1788, and the 5th article, embodying as it does a summary of the entire act, was specifically ratified and confirmed by that State. This was an incorporation of the ordinance into her act of cession. It was conceded, in the argument, that the authority of Congress was not adequate to the enactment of the ordinance, and that it cannot be supported upon the Articles of Confederation. To a part of the engagements, the assent of nine States was required, and for another portion no provision had been made in those articles. Mr. Madison said, in a writing nearly contemporary, but before the confirmatory act of Virginia, "Congress have proceeded to form new States, to erect temporary Governments, to appoint officers for them, and to prescribe the conditions on which such States shall be admitted into the Confederacy; all this has been done, and done without the least color of constitutional authority." (Federalist, No. 38.) Richard Henry Lee, one of the committee who reported the ordinance to Congress, transmitted it to General Washington, (15th July, 1787,) saying, "It seemed necessary, for the security of property among uninformed and perhaps licentious people, as the greater part of those who go there are, that a strong-toned Government should exist, and the rights of property be clearly defined." The consent of all the States represented in Congress, the consent of the Legislature of Virginia, the consent of the inhabitants of the Territory, all concur to support the authority of this enactment. It is apparent, in the frame of the Constitution, that the Convention recognised its validity, and adjusted parts of their work with reference to it. The authority to admit new States into the Union, the omission to provide distinctly for Territorial Governments, and the clause limiting the foreign slave trade to States then existing, which might not prohibit it, show that they regarded this Territory as provided with a Government, and organized permanently with a restriction on the subject of slavery. Justice Chase, in the opinion already cited, says of the Government before, and it is in some measure true during the Confederation, that "the powers of Congress originated from necessity, and arose out of and were only limited by events, or, in other words, they were revolutionary in their very nature. Their extent depended upon the exigencies and necessities of public affairs;" and there is only one rule of construction, in regard to the acts done, which will fully support them, viz: that the powers actually exercised were rightfully exercised, wherever they were supported by the implied sanction of the State Legislatures, and by the ratifications of the people.

The clauses in the 3d section of the 4th article of the Constitution, relative to the admission of new States, and the disposal and regulation of the territory of the United States, were adopted without debate in the Convention.

There was a warm discussion on the clauses that relate to the subdivision of the States, and the reservation of the claims of the United States and each of the States from any prejudice. The Maryland members revived the controversy in regard to the Crown lands of the Southwest. There was nothing to indicate any reference to a government of Territories not included within the limits of the Union; and the whole discussion demonstrates that the Convention was consciously dealing with a Territory whose condition, as to government, had been arranged by a fundamental and unalterable compact.

An examination of this clause of the Constitution, by the light of the circumstances in which the Convention was placed, will aid us to determine its significance. The first clause is, "that new States may be admitted by the Congress to this Union." The condition of Kentucky, Vermont, Rhode Island, and the new States to be formed in the Northwest, suggested this, as a necessary addition to the powers of Congress. The next clause, providing for the subdivision of States, and the parties to consent to such an alteration, was required, by the plans on foot, for changes in Massachusetts, New York, Pennsylvania, North Carolina, and Georgia. The clause which enables Congress to dispose of and make regulations respecting the public domain, was demanded by the exigencies of an exhausted treasury and a disordered finance, for relief by sales, and the preparation for sales, of the public lands; and the last clause, that nothing in the Constitution should prejudice the claims of the United States or a particular State, was to quiet the jealousy and irritation of those who had claimed for the United States all the unappropriated lands. I look in vain, among the discussions of the time, for the assertion of a supreme sovereignty for Congress over the territory then belonging to the United States, or that they might thereafter acquire. I seek in vain for an annunciation that a consolidated power had been inaugurated, whose subject comprehended an empire, and which had no restriction but the discretion of Congress. This disturbing element of the Union entirely escaped the apprehensive previsions of Samuel Adams, George Clinton, Luther Martin, and Patrick Henry; and, in respect to dangers from power vested in a central Government over distant settlements, colonies, or provinces, their instincts were always alive. Not a word escaped them, to warn their countrymen, that here was a power to threaten the landmarks of this federative Union, and with them the safeguards of popular and constitutional liberty; or that under this article there might be introduced, on our soil, a single Government over a vast extent of country—a Government foreign to the persons over whom it might be exercised, and capable of binding those not represented, by statutes, in all cases whatever. I find nothing to authorize these enormous pretensions, nothing in the expositions of the friends of the Constitution, nothing in the expressions of alarm by its opponents—expressions which have since been developed as prophecies. Every portion of the United States was then provided with a municipal Government, which this Constitution was not designed to supersede, but merely to modify as to its conditions.

The compacts of cession by North Carolina and Georgia are subsequent to the Constitution. They adopt the ordinance of 1787, except the clause respecting slavery. But the precautionary repudiation of that article forms an argument quite as satisfactory to the advocates for Federal power, as its introduction would have done. The refusal of a power to Congress to legislate in one place, seems to justify the seizure of the same power when another place for its exercise is found.

This proceeds from a radical error, which lies at the foundation of much of this discussion. It is, that the Federal Government may lawfully do whatever is not directly prohibited by the Constitution. This would have been a fundamental error, if no amendments to the Constitution had been made. But the final expression of the will of the people of the States, in the 10th amendment, is, that the powers of the Federal Government are limited to the grants of the Constitution.

Before the cession of Georgia was made, Congress asserted rights, in respect to a part of her territory, which require a passing notice. In 1798 and 1800, acts for the settlement of limits with Georgia, and to establish a Government in the Mississippi Territory, were adopted. A Territorial Government was organized, between the Chattahoochee and Mississippi rivers. This was within the limits of Georgia. These acts dismembered Georgia. They established a separate Government upon her soil, while they rather derisively professed, "that the establishment of that Government shall in no respects impair the rights of the State of Georgia, either to the jurisdiction or soil of the Territory." The Constitution provided that the importation of such persons as any of the existing States shall think proper to admit, shall not be prohibited by Congress before 1808. By these enactments, a prohibition was placed upon the importation of slaves into Georgia, although her Legislature had made none.

This court have repeatedly affirmed the paramount claim of Georgia to this Territory. They have denied the existence of any title in the United States. (6 C.R., 87; 12 Wh., 523; 3 How., 212; 13 How., 381.) Yet these acts were cited in the argument as precedents to show the power of Congress in the Territories. These statutes were the occasion of earnest expostulation and bitter remonstrance on the part of the authorities of the State, and the memory of their injustice and wrong remained long after the legal settlement of the controversy by the compact of 1802. A reference to these acts terminates what I have to say upon the Constitutions of the Territory within the original limits of the United States. These Constitutions were framed by the concurrence of the States making the cessions, and Congress, and were tendered to immigrants who might be attracted to the vacant territory. The legislative powers of the officers of this Government were limited to the selection of laws from the States; and provision was made for the introduction of popular institutions, and their emancipation from Federal control, whenever a suitable opportunity occurred. The limited reservation of legislative power to the officers of the Federal Government was excused, on the plea of necessity; and the probability is, that the clauses respecting slavery embody some compromise among the statesmen of that time; beyond these, the distinguishing features of the system which the patriots of the Revolution had claimed as their birthright, from Great Britain, predominated in them.

The acquisition of Louisiana, in 1803, introduced another system into the United States. This vast province was ceded by Napoleon, and its population had always been accustomed to a viceroyal Government, appointed by the Crowns of France or Spain. To establish a Government constituted on similar principles, and with like conditions, was not an unnatural proceeding.

But there was great difficulty in finding constitutional authority for the measure. The third section of the fourth article of the Constitution was introduced into the Constitution, on the motion of Mr. Gouverneur Morris. In 1803, he was appealed to for information in regard to its meaning. He answers: "I am very certain I had it not in contemplation to insert a decree de coercendo imperio in the Constitution of America.... I knew then, as well as I do now, that all North America must at length be annexed to us. Happy indeed, if the lust of dominion stop here. It would therefore have been perfectly utopian to oppose a paper restriction to the violence of popular sentiment, in a popular Government." (3 Mor. Writ., 185.) A few days later, he makes another reply to his correspondent. "I perceive," he says, "I mistook the drift of your inquiry, which substantially is, whether Congress can admit, as a new State, territory which did not belong to the United States when the Constitution was made. In my opinion, they cannot. I always thought, when we should acquire Canada and Louisiana, it would be proper to GOVERN THEM AS PROVINCES, AND ALLOW THEM NO VOICE in our councils. In wording the third SECTION OF THE fourth article, I went as far as circumstances would permit, to establish the exclusion. CANDOR OBLIGES ME TO ADD MY BELIEF, THAT HAD IT BEEN MORE POINTEDLY EXPRESSED, A STRONG OPPOSITION WOULD HAVE BEEN MADE." (3 Mor. Writ., 192.) The first Territorial Government of Louisiana was an Imperial one, founded upon a French or Spanish model. For a time, the Governor, Judges, Legislative Council, Marshal, Secretary, and officers of the militia, were appointed by the President.[3]

[Footnote 3: Mr. Varnum said: "The bill provided such a Government as had never been known in the United States." Mr. Eustis: "The Government laid down in this bill is certainly a new thing in the United States." Mr. Lucas: "It has been remarked, that this bill establishes elementary principles never previously introduced in the Government of any Territory of the United States. Granting the truth of this observation," &c., &c. Mr. Macon: "My first objection to the principle contained in this section is, that it establishes a species of government unknown to the United States." Mr. Boyle: "Were the President an angel instead of a man, I would not clothe him with this power." Mr. G.W. Campbell: "On examining the section, it will appear that it really establishes a complete despotism." Mr. Sloan: "Can anything be more repugnant to the principles of just government? Can anything be more despotic?"—Annals of Congress, 1803-'4.]

Besides these anomalous arrangements, the acquisition gave rise to jealous inquiries, as to the influence it would exert in determining the men and States that were to be "the arbiters and rulers" of the destinies of the Union; and unconstitutional opinions, having for their aim to promote sectional divisions, were announced and developed. "Something," said an eminent statesman, "something has suggested to the members of Congress the policy of acquiring geographical majorities. This is a very direct step towards disunion, for it must foster the geographical enmities by which alone it can be effected. This something must be a contemplation of particular advantages to be derived from such majorities; and is it not notorious that they consist of nothing else but usurpations over persons and property, by which they can regulate the internal wealth and prosperity of States and individuals?"

The most dangerous of the efforts to employ a geographical political power, to perpetuate a geographical preponderance in the Union, is to be found in the deliberations upon the act of the 6th of March, 1820, before cited. The attempt consisted of a proposal to exclude Missouri from a place in the Union, unless her people would adopt a Constitution containing a prohibition upon the subject of slavery, according to a prescription of Congress. The sentiment is now general, if not universal, that Congress had no constitutional power to impose the restriction. This was frankly admitted at the bar, in the course of this argument. The principles which this court have pronounced condemn the pretension then made on behalf of the legislative department. In Groves v. Slaughter, (15 Pet.,) the Chief Justice said: "The power over this subject is exclusively with the several States, and each of them has a right to decide for itself whether it will or will not allow persons of this description to be brought within its limits." Justice McLean said: "The Constitution of the United States operates alike in all the States, and one State has the same power over the subject of slavery as every other State." In Pollard's Lessee v. Hagan, (3 How., 212,) the court say: "The United States have no constitutional capacity to exercise municipal jurisdiction, sovereignty, or eminent domain, within the limits of a State or elsewhere, except in cases where it is delegated, and the court denies the faculty of the Federal Government to add to its powers by treaty or compact."

This is a necessary consequence, resulting from the nature of the Federal Constitution, which is a federal compact among the States, establishing a limited Government, with powers delegated by the people of distinct and independent communities, who reserved to their State Governments, and to themselves, the powers they did not grant. This claim to impose a restriction upon the people of Missouri involved a denial of the constitutional relations between the people of the States and Congress, and affirmed a concurrent right for the latter, with their people, to constitute the social and political system of the new States. A successful maintenance of this claim would have altered the basis of the Constitution. The new States would have become members of a Union defined in part by the Constitution and in part by Congress. They would not have been admitted to "this Union." Their sovereignty would have been restricted by Congress as well as the Constitution. The demand was unconstitutional and subversive, but was prosecuted with an energy, and aroused such animosities among the people, that patriots, whose confidence had not failed during the Revolution, began to despair for the Constitution.[4] Amid the utmost violence of this extraordinary contest, the expedient contained in the eighth section of this act was proposed, to moderate it, and to avert the catastrophe it menaced. It was not seriously debated, nor were its constitutional aspects severely scrutinized by Congress. For the first time, in the history of the country, has its operation been embodied in a case at law, and been presented to this court for their judgment. The inquiry is, whether there are conditions in the Constitutions of the Territories which subject the capacity and status of persons within their limits to the direct action of Congress. Can Congress determine the condition and status of persons who inhabit the Territories?

[Footnote 4: Mr. Jefferson wrote: "The Missouri question is the most portentous one that ever threatened our Union. In the gloomiest moments of the revolutionary war, I never had any apprehension equal to that I feel from this source."]

The Constitution permits Congress to dispose of and to make all needful rules and regulations respecting the territory or other property belonging to the United States. This power applies as well to territory belonging to the United States within the States, as beyond them. It comprehends all the public domain, wherever it may be. The argument is, that the power to make "ALL needful rules and regulations" "is a power of legislation," "a full legislative power;" "that it includes all subjects of legislation in the territory," and is without any limitations, except the positive prohibitions which affect all the powers of Congress. Congress may then regulate or prohibit slavery upon the public domain within the new States, and such a prohibition would permanently affect the capacity of a slave, whose master might carry him to it. And why not? Because no power has been conferred on Congress. This is a conclusion universally admitted. But the power to "make rules and regulations respecting the territory" is not restrained by State lines, nor are there any constitutional prohibitions upon its exercise in the domain of the United States within the States; and whatever rules and regulations respecting territory Congress may constitutionally make are supreme, and are not dependent on the situs of "the territory."

The author of the Farmer's Letters, so famous in the ante-revolutionary history, thus states the argument made by the American loyalists in favor of the claim of the British Parliament to legislate in all cases whatever over the colonies: "It has been urged with great vehemence against us," he says, "and it seems to be thought their FORT by our adversaries, that a power of regulation is a power of legislation; and a power of legislation, if constitutional, must be universal and supreme, in the utmost sense of the word. It is therefore concluded that the colonies, by acknowledging the power of regulation, acknowledged every other power."

This sophism imposed upon a portion of the patriots of that day. Chief Justice Marshall, in his life of Washington, says "that many of the best-informed men in Massachusetts had perhaps adopted the opinion of the parliamentary right of internal government over the colonies;" "that the English statute book furnishes many instances of its exercise;" "that in no case recollected, was their authority openly controverted;" and "that the General Court of Massachusetts, on a late occasion, openly recognised the principle." (Marsh. Wash., v. 2, p. 75, 76.)

But the more eminent men of Massachusetts rejected it; and another patriot of the time employs the instance to warn us of "the stealth with which oppression approaches," and "the enormities towards which precedents travel." And the people of the United States, as we have seen, appealed to the last argument, rather than acquiesce in their authority. Could it have been the purpose of Washington and his illustrious associates, by the use of ambiguous, equivocal, and expansive words, such as "rules," "regulations," "territory," to re-establish in the Constitution of their country that fort which had been prostrated amid the toils and with the sufferings and sacrifices of seven years of war? Are these words to be understood as the Norths, the Grenvilles, Hillsboroughs, Hutchinsons, and Dunmores—in a word, as George III would have understood them—or are we to look for their interpretation to Patrick Henry or Samuel Adams, to Jefferson, and Jay, and Dickinson; to the sage Franklin, or to Hamilton, who from his early manhood was engaged in combating British constructions of such words? We know that the resolution of Congress of 1780 contemplated that the new States to be formed under their recommendation were to have the same rights of sovereignty, freedom, and independence, as the old. That every resolution, cession, compact, and ordinance, of the States, observed the same liberal principle. That the Union of the Constitution is a union formed of equal States; and that new States, when admitted, were to enter "this Union." Had another union been proposed in "any pointed manner," it would have encountered not only "strong" but successful opposition. The disunion between Great Britain and her colonies originated in the antipathy of the latter to "rules and regulations" made by a remote power respecting their internal policy. In forming the Constitution, this fact was ever present in the minds of its authors. The people were assured by their most trusted statesmen "that the jurisdiction of the Federal Government is limited to certain enumerated objects, which concern all members of the republic," and "that the local or municipal authorities form distinct portions of supremacy, no more subject within their respective spheres to the general authority, than the general authority is subject to them within its own sphere." Still, this did not content them. Under the lead of Hancock and Samuel Adams, of Patrick Henry and George Mason, they demanded an explicit declaration that no more power was to be exercised than they had delegated. And the ninth and tenth amendments to the Constitution were designed to include the reserved rights of the States, and the people, within all the sanctions of that instrument, and to bind the authorities, State and Federal, by the judicial oath it prescribes, to their recognition and observance. Is it probable, therefore, that the supreme and irresponsible power, which is now claimed for Congress over boundless territories, the use of which cannot fail to react upon the political system of the States, to its subversion, was ever within the contemplation of the statesmen who conducted the counsels of the people in the formation of this Constitution? When the questions that came to the surface upon the acquisition of Louisiana were presented to the mind of Jefferson, he wrote: "I had rather ask an enlargement of power from the nation, where it is found necessary, than to assume it by a construction which would make our powers boundless. Our peculiar security is in the possession of a written Constitution. Let us not make it blank paper by construction. I say the same as to the opinion of those who consider the grant of the treaty-making power as boundless. If it is, then we have no Constitution. If it has bounds, they can be no others than the definitions of the powers which that instrument gives. It specifies and delineates the operations permitted to the Federal Government, and gives the powers necessary to carry them into execution." The publication of the journals of the Federal Convention in 1819, of the debates reported by Mr. Madison in 1840, and the mass of private correspondence of the early statesmen before and since, enable us to approach the discussion of the aims of those who made the Constitution, with some insight and confidence.

I have endeavored, with the assistance of these, to find a solution for the grave and difficult question involved in this inquiry. My opinion is, that the claim for Congress of supreme power in the Territories, under the grant to "dispose of and make all needful rules and regulations respecting territory," is not supported by the historical evidence drawn from the Revolution, the Confederation, or the deliberations which preceded the ratification of the Federal Constitution. The ordinance of 1787 depended upon the action of the Congress of the Confederation, the assent of the State of Virginia, and the acquiescence of the people who recognised the validity of that plea of necessity which supported so many of the acts of the Governments of that time; and the Federal Government accepted the ordinance as a recognised and valid engagement of the Confederation.

In referring to the precedents of 1798 and 1800, I find the Constitution was plainly violated by the invasion of the rights of a sovereign State, both of soil and jurisdiction; and in reference to that of 1804, the wisest statesmen protested against it, and the President more than doubted its policy and the power of the Government.

Mr. John Quincy Adams, at a later period, says of the last act, "that the President found Congress mounted to the pitch of passing those acts, without inquiring where they acquired the authority, and he conquered his own scruples as they had done theirs." But this court cannot undertake for themselves the same conquest. They acknowledge that our peculiar security is in the possession of a written Constitution, and they cannot make it blank paper by construction.

They look to its delineation of the operations of the Federal Government, and they must not exceed the limits it marks out, in their administration. The court have said "that Congress cannot exercise municipal jurisdiction, sovereignty, or eminent domain, within the limits of a State or elsewhere, beyond what has been delegated." We are then to find the authority for supreme power in the Territories in the Constitution. What are the limits upon the operations of a Government invested with legislative, executive, and judiciary powers, and charged with the power to dispose of and to make all needful rules and regulations respecting a vast public domain? The feudal system would have recognised the claim made on behalf of the Federal Government for supreme power over persons and things in the Territories, as an incident to this title—that is, the title to dispose of and make rules and regulations respecting it.

The Norman lawyers of William the Conqueror would have yielded an implicit assent to the doctrine, that a supreme sovereignty is an inseparable incident to a grant to dispose of and to make all needful rules and regulations respecting the public domain. But an American patriot, in contrasting the European and American systems, may affirm, "that European sovereigns give lands to their colonists, but reserve to themselves a power to control their property, liberty, and privileges; but the American Government sells the lands belonging to the people of the several States (i.e., United States) to their citizens, who are already in the possession of personal and political rights, which the Government did not give, and cannot take away." And the advocates for Government sovereignty in the Territories have been compelled to abate a portion of the pretensions originally made in its behalf, and to admit that the constitutional prohibitions upon Congress operate in the Territories. But a constitutional prohibition is not requisite to ascertain a limitation upon the authority of the several departments of the Federal Government. Nor are the States or people restrained by any enumeration or definition of their rights or liberties.

To impair or diminish either, the department must produce an authority from the people themselves, in their Constitution; and, as we have seen, a power to make rules and regulations respecting the public domain does not confer a municipal sovereignty over persons and things upon it. But as this is "thought their fort" by our adversaries, I propose a more definite examination of it. We have seen, Congress does not dispose of or make rules and regulations respecting domain belonging to themselves, but belonging to the United States.

These conferred on their mandatory, Congress, authority to dispose of the territory which belonged to them in common; and to accomplish that object beneficially and effectually, they gave an authority to make suitable rules and regulations respecting it. When the power of disposition is fulfilled, the authority to make rules and regulations terminates, for it attaches only upon territory "belonging to the United States."

Consequently, the power to make rules and regulations, from the nature of the subject, is restricted to such administrative and conservatory acts as are needful for the preservation of the public domain, and its preparation for sale or disposition. The system of land surveys; the reservations for schools, internal improvements, military sites, and public buildings; the pre-emption claims of settlers; the establishment of land offices, and boards of inquiry, to determine the validity of land titles; the modes of entry, and sale, and of conferring titles; the protection of the lands from trespass and waste; the partition of the public domain into municipal subdivisions, having reference to the erection of Territorial Governments and States; and perhaps the selection, under their authority, of suitable laws for the protection of the settlers, until there may be a sufficient number of them to form a self-sustaining municipal Government—these important rules and regulations will sufficiently illustrate the scope and operation of the 3d section of the 4th article of the Constitution. But this clause in the Constitution does not exhaust the powers of Congress within the territorial subdivisions, or over the persons who inhabit them. Congress may exercise there all the powers of Government which belong to them as the Legislature of the United States, of which these Territories make a part. (Loughborough v. Blake, 5 Wheat., 317.) Thus the laws of taxation, for the regulation of foreign, Federal, and Indian commerce, and so for the abolition of the slave trade, for the protection of copyrights and inventions, for the establishment of postal communication and courts of justice, and for the punishment of crimes, are as operative there as within the States. I admit that to mark the bounds for the jurisdiction of the Government of the United States within the Territory, and of its power in respect to persons and things within the municipal subdivisions it has created, is a work of delicacy and difficulty, and, in a great measure, is beyond the cognizance of the judiciary department of that Government. How much municipal power may be exercised by the people of the Territory, before their admission to the Union, the courts of justice cannot decide. This must depend, for the most part, on political considerations, which cannot enter into the determination of a case of law or equity. I do not feel called upon to define the jurisdiction of Congress. It is sufficient for the decision of this case to ascertain whether the residuary sovereignty of the States or people has been invaded by the 8th section of the act of 6th March, 1820, I have cited, in so far as it concerns the capacity and status of persons in the condition and circumstances of the plaintiff and his family.

These States, at the adoption of the Federal Constitution, were organized communities, having distinct systems of municipal law, which, though derived from a common source, and recognising in the main similar principles, yet in some respects had become unlike, and on a particular subject promised to be antagonistic.

Their systems provided protection for life, liberty, and property, among their citizens, and for the determination of the condition and capacity of the persons domiciled within their limits. These institutions, for the most part, were placed beyond the control of the Federal Government. The Constitution allows Congress to coin money, and regulate its value; to regulate foreign and Federal commerce; to secure, for a limited period, to authors and inventors, a property in their writings and discoveries; and to make rules concerning captures in war; and, within the limits of these powers, it has exercised, rightly, to a greater or less extent, the power to determine what shall and what shall not be property.

But the great powers of war and negotiation, finance, postal communication, and commerce, in general, when employed in respect to the property of a citizen, refer to, and depend upon, the municipal laws of the States, to ascertain and determine what is property, and the rights of the owner, and the tenure by which it is held.

Whatever these Constitutions and laws validly determine to be property, it is the duty of the Federal Government, through the domain of jurisdiction merely Federal, to recognise to be property.

And this principle follows from the structure of the respective Governments, State and Federal, and their reciprocal relations. They are different agents and trustees of the people of the several States, appointed with different powers and with distinct purposes, but whose acts, within the scope of their respective jurisdictions, are mutually obligatory. They are respectively the depositories of such powers of legislation as the people were willing to surrender, and their duty is to co-operate within their several jurisdictions to maintain the rights of the same citizens under both Governments unimpaired. A proscription, therefore, of the Constitution and laws of one or more States, determining property, on the part of the Federal Government, by which the stability of its social system may be endangered, is plainly repugnant to the conditions on which the Federal Constitution was adopted, or which that Government was designed to accomplish. Each of the States surrendered its powers of war and negotiation, to raise armies and to support a navy, and all of these powers are sometimes required to preserve a State from disaster and ruin. The Federal Government was constituted to exercise these powers for the preservation of the States, respectively, and to secure to all their citizens the enjoyment of the rights which were not surrendered to the Federal Government. The provident care of the statesmen who projected the Constitution was signalized by such a distribution of the powers of Government as to exclude many of the motives and opportunities for promoting provocations and spreading discord among the States, and for guarding against those partial combinations, so destructive of the community of interest, sentiment, and feeling, which are so essential to the support of the Union. The distinguishing features of their system consist in the exclusion of the Federal Government from the local and internal concerns of, and in the establishment of an independent internal Government within, the States. And it is a significant fact in the history of the United States, that those controversies which have been productive of the greatest animosity, and have occasioned most peril to the peace of the Union, have had their origin in the well-sustained opinion of a minority among the people, that the Federal Government had overstepped its constitutional limits to grant some exclusive privilege, or to disturb the legitimate distribution of property or power among the States or individuals. Nor can a more signal instance of this be found than is furnished by the act before us. No candid or rational man can hesitate to believe, that if the subject of the eighth section of the act of March, 1820, had never been introduced into Congress and made the basis of legislation, no interest common to the Union would have been seriously affected. And, certainly, the creation, within this Union, of large confederacies of unfriendly and frowning States, which has been the tendency, and, to an alarming extent, the result, produced by the agitation arising from it, does not commend it to the patriot or statesman. This court have determined that the intermigration of slaves was not committed to the jurisdiction or control of Congress. Wherever a master is entitled to go within the United States, his slave may accompany him, without any impediment from, or fear of, Congressional legislation or interference. The question then arises, whether Congress, which can exercise no jurisdiction over the relations of master and slave within the limits of the Union, and is bound to recognise and respect the rights and relations that validly exist under the Constitutions and laws of the States, can deny the exercise of those rights, and prohibit the continuance of those relations, within the Territories.

And the citation of State statutes prohibiting the immigration of slaves, and of the decisions of State courts enforcing the forfeiture of the master's title in accordance with their rule, only darkens the discussion. For the question is, have Congress the municipal sovereignty in the Territories which the State Legislatures have derived from the authority of the people, and exercise in the States?

And this depends upon the construction of the article in the Constitution before referred to.

And, in my opinion, that clause confers no power upon Congress to dissolve the relations of the master and slave on the domain of the United States, either within or without any of the States.

The eighth section of the act of Congress of the 6th of March, 1820, did not, in my opinion, operate to determine the domestic condition and status of the plaintiff and his family during their sojourn in Minnesota Territory, or after their return to Missouri.

The question occurs as to the judgment to be given in this case. It appeared upon the trial that the plaintiff, in 1834, was in a state of slavery in Missouri, and he had been in Missouri for near fifteen years in that condition when this suit was brought. Nor does it appear that he at any time possessed another state or condition, de facto. His claim to freedom depends upon his temporary elocation, from the domicil of his origin, in company with his master, to communities where the law of slavery did not prevail. My examination is confined to the case, as it was submitted upon uncontested evidence, upon appropriate issues to the jury, and upon the instructions given and refused by the court upon that evidence. My opinion is, that the opinion of the Circuit Court was correct upon all the claims involved in those issues, and that the verdict of the jury was justified by the evidence and instructions.

The jury have returned that the plaintiff and his family are slaves.

Upon this record, it is apparent that this is not a controversy between citizens of different States; and that the plaintiff, at no period of the life which has been submitted to the view of the court, has had a capacity to maintain a suit in the courts of the United States. And in so far as the argument of the Chief Justice upon the plea in abatement has a reference to the plaintiff or his family, in any of the conditions or circumstances of their lives, as presented in the evidence, I concur in that portion of his opinion. I concur in the judgment which expresses the conclusion that the Circuit Court should not have rendered a general judgment.

The capacity of the plaintiff to sue is involved in the pleas in bar, and the verdict of the jury discloses an incapacity under the Constitution. Under the Constitution of the United States, his is an incapacity to sue in their courts, while, by the laws of Missouri, the operation of the verdict would be more extensive. I think it a safe conclusion to enforce the lesser disability imposed by the Constitution of the United States, and leave to the plaintiff all his rights in Missouri. I think the judgment should be affirmed, on the ground that the Circuit Court had no jurisdiction, or that the case should be reversed and remanded, that the suit may be dismissed.

* * * * *

Mr. Justice CATRON.

The defendant pleaded to the jurisdiction of the Circuit Court, that the plaintiff was a negro of African blood; the descendant of Africans, who had been imported and sold in this country as slaves, and thus had no capacity as a citizen of Missouri to maintain a suit in the Circuit Court. The court sustained a demurrer to this plea, and a trial was had upon the pleas, of the general issue, and also that the plaintiff and his family were slaves, belonging to the defendant. In this trial, a verdict was given for the defendant.

The judgment of the Circuit Court upon the plea in abatement is not open, in my opinion, to examination in this court upon the plaintiff's writ.

The judgment was given for him conformably to the prayer of his demurrer. He cannot assign an error in such a judgment. (Tidd's Pr., 1163; 2 Williams's Saund., 46 a; 2 Iredell N.C., 87; 2 W. and S., 391.) Nor does the fact that the judgment was given on a plea to the jurisdiction, avoid the application of this rule. (Capron v. Van Noorden, 2 Cr., 126; 6 Wend., 465; 7 Met., 598; 5 Pike, 1005.)

The declaration discloses a case within the jurisdiction of the court—a controversy between citizens of different States. The plea in abatement, impugning these jurisdictional averments, was waived when the defendant answered to the declaration by pleas to the merits. The proceedings on that plea remain a part of the technical record, to show the history of the case, but are not open to the review of this court by a writ of error. The authorities are very conclusive on this point. Shepherd v. Graves, 14 How., 505; Bailey v. Dozier, 6 How., 23; 1 Stewart, (Alabama,) 46; 10 Ben. Monroe, (Kentucky,) 555; 2 Stewart, (Alabama,) 370, 443; 2 Scammon, (Illinois,) 78. Nor can the court assume, as admitted facts, the averments of the plea from the confession of the demurrer. That confession was for a single object, and cannot be used for any other purpose than to test the validity of the plea. Tompkins v. Ashley, 1 Moody and Mackin, 32; 33 Maine, 96, 100.

There being nothing in controversy here but the merits, I will proceed to discuss them.

The plaintiff claims to have acquired property in himself, and became free, by being kept in Illinois during two years.

The Constitution, laws, and policy, of Illinois, are somewhat peculiar respecting slavery. Unless the master becomes an inhabitant of that State, the slaves he takes there do not acquire their freedom; and if they return with their master to the slave State of his domicil, they cannot assert their freedom after their return. For the reasons and authorities on this point, I refer to the opinion of my brother Nelson, with which I not only concur, but think his opinion is the most conclusive argument on the subject within my knowledge.

It is next insisted for the plaintiff, that his freedom (and that of his wife and eldest child) was obtained by force of the act of Congress of 1820, usually known as the Missouri compromise act, which declares: "That in all that territory ceded by France to the United States, which lies north of thirty-six degrees thirty minutes north latitude, slavery and involuntary servitude shall be, and are hereby, forever prohibited."

From this prohibition, the territory now constituting the State of Missouri was excepted; which exception to the stipulation gave it the designation of a compromise.

The first question presented on this act is, whether Congress had power to make such compromise. For, if power was wanting, then no freedom could be acquired by the defendant under the act.

That Congress has no authority to pass laws and bind men's rights beyond the powers conferred by the Constitution, is not open to controversy. But it is insisted that, by the Constitution, Congress has power to legislate for and govern the Territories of the United States, and that by force of the power to govern, laws could be enacted, prohibiting slavery in any portion of the Louisiana Territory; and, of course, to abolish slavery in all parts of it, whilst it was, or is, governed as a Territory.

My opinion is, that Congress is vested with power to govern the Territories of the United States by force of the third section of the fourth article of the Constitution. And I will state my reasons for this opinion.

Almost every provision in that instrument has a history that must be understood, before the brief and sententious language employed can be comprehended in the relations its authors intended. We must bring before us the state of things presented to the Convention, and in regard to which it acted, when the compound provision was made, declaring: 1st. That "new States may be admitted by the Congress into this Union." 2d. "The Congress shall have power to dispose of and make all needful rules and regulations respecting the territory or other property belonging to the United States. And nothing in this Constitution shall be so construed as to prejudice any claims of the United States, or any particular State."

Having ascertained the historical facts giving rise to these provisions, the difficulty of arriving at the true meaning of the language employed will be greatly lessened.

The history of these facts is substantially as follows:

The King of Great Britain, by his proclamation of 1763, virtually claimed that the country west of the mountains had been conquered from France, and ceded to the Crown of Great Britain by the treaty of Paris of that year, and he says: "We reserve it under our sovereignty, protection, and dominion, for the use of the Indians."

This country was conquered from the Crown of Great Britain, and surrendered to the United States by the treaty of peace of 1783. The colonial charters of Virginia, North Carolina, and Georgia, included it. Other States set up pretensions of claim to some portions of the territory north of the Ohio, but they were of no value, as I suppose. (5 Wheat., 375.)

As this vacant country had been won by the blood and treasure of all the States, those whose charters did not reach it, insisted that the country belonged to the States united, and that the lands should be disposed of for the benefit of the whole; and to which end, the western territory should be ceded to the States united. The contest was stringent and angry, long before the Convention convened, and deeply agitated that body. As a matter of justice, and to quiet the controversy, Virginia consented to cede the country north of the Ohio as early as 1783; and in 1784 the deed of cession was executed, by her delegates in the Congress of the Confederation, conveying to the United States in Congress assembled, for the benefit of said States, "all right, title, and claim, as well of soil as of jurisdiction, which this Commonwealth hath to the territory or tract of country within the limits of the Virginia charter, situate, lying, and being to the northwest of the river Ohio." In 1787, (July 13,) the ordinance was passed by the old Congress to govern the Territory.

Massachusetts had ceded her pretension of claim to western territory in 1785, Connecticut hers in 1786, and New York had ceded hers. In August, 1787, South Carolina ceded to the Confederation her pretension of claim to territory west of that State. And North Carolina was expected to cede hers, which she did do, in April, 1790. And so Georgia was confidently expected to cede her large domain, now constituting the territory of the States of Alabama and Mississippi.

At the time the Constitution was under consideration, there had been ceded to the United States, or was shortly expected to be ceded, all the western country, from the British Canada line to Florida, and from the head of the Mississippi almost to its mouth, except that portion which now constitutes the State of Kentucky.

Although Virginia had conferred on the Congress of the Confederation power to govern the Territory north of the Ohio, still, it cannot be denied, as I think, that power was wanting to admit a new State under the Articles of Confederation.

With these facts prominently before the Convention, they proposed to accomplish these ends:

1st. To give power to admit new States.

2d. To dispose of the public lands in the Territories, and such as might remain undisposed of in the new States after they were admitted.

And, thirdly, to give power to govern the different Territories as incipient States, not of the Union, and fit them for admission. No one in the Convention seems to have doubted that these powers were necessary. As early as the third day of its session, (May 29th,) Edmund Randolph brought forward a set of resolutions containing nearly all the germs of the Constitution, the tenth of which is as follows:

"Resolved, That provision ought to be made for the admission of States lawfully arising within the limits of the United States, whether from a voluntary junction of government and territory or otherwise, with the consent of a number of voices in the National Legislature less than the whole."

August 18th, Mr. Madison submitted, in order to be referred to the committee of detail, the following powers as proper to be added to those of the General Legislature:

"To dispose of the unappropriated lands of the United States." "To institute temporary Governments for new States arising therein." (3 Madison Papers, 1353.)

These, with the resolution, that a district for the location of the seat of Government should be provided, and some others, were referred, without a dissent, to the committee of detail, to arrange and put them into satisfactory language.

Gouverneur Morris constructed the clauses, and combined the views of a majority on the two provisions, to admit new States; and secondly, to dispose of the public lands, and to govern the Territories, in the mean time, between the cessions of the States and the admission into the Union of new States arising in the ceded territory. (3 Madison Papers, 1456 to 1466.)

It was hardly possible to separate the power "to make all needful rules and regulations" respecting the government of the territory and the disposition of the public lands.

North of the Ohio, Virginia conveyed the lands, and vested the jurisdiction in the thirteen original States, before the Constitution was formed. She had the sole title and sole sovereignty, and the same power to cede, on any terms she saw proper, that the King of England had to grant the Virginia colonial charter of 1609, or to grant the charter of Pennsylvania to William Penn. The thirteen States, through their representatives and deputed ministers in the old Congress, had the same right to govern that Virginia had before the cession. (Baldwin's Constitutional Views, 90.) And the sixth article of the Constitution adopted all engagements entered into by the Congress of the Confederation, as valid against the United States; and that the laws, made in pursuance of the new Constitution, to carry out this engagement, should be the supreme law of the land, and the judges bound thereby. To give the compact, and the ordinance, which was part of it, full effect under the new Government, the act of August 7th, 1789, was passed, which declares, "Whereas, in order that the ordinance of the United States in Congress assembled, for the government of the Territory northwest of the river Ohio, may have full effect, it is requisite that certain provisions should be made, so as to adapt the same to the present Constitution of the United States." It is then provided that the Governor and other officers should be appointed by the President, with the consent of the Senate; and be subject to removal, &c., in like manner that they were by the old Congress, whose functions had ceased.

By the powers to govern, given by the Constitution, those amendments to the ordinance could be made, but Congress guardedly abstained from touching the compact of Virginia, further than to adapt it to the new Constitution.

It is due to myself to say, that it is asking much of a judge, who has for nearly twenty years been exercising jurisdiction, from the western Missouri line to the Rocky Mountains, and, on this understanding of the Constitution, inflicting the extreme penalty of death for crimes committed where the direct legislation of Congress was the only rule, to agree that he had been all the while acting in mistake, and as an usurper.

More than sixty years have passed away since Congress has exercised power to govern the Territories, by its legislation directly, or by Territorial charters, subject to repeal at all times, and it is now too late to call that power into question, if this court could disregard its own decisions; which it cannot do, as I think. It was held in the case of Cross v. Harrison, (16 How., 193-'4,) that the sovereignty of California was in the United States, in virtue of the Constitution, by which power had been given to Congress to dispose of and make all needful rules and regulations respecting the territory or other property belonging to the United States, with the power to admit new States into the Union. That decision followed preceding ones, there cited. The question was then presented, how it was possible for the judicial mind to conceive that the United States Government, created solely by the Constitution, could, by a lawful treaty, acquire territory over which the acquiring power had no jurisdiction to hold and govern it, by force of the instrument under whose authority the country was acquired; and the foregoing was the conclusion of this court on the proposition. What was there announced, was most deliberately done, and with a purpose. The only question here is, as I think, how far the power of Congress is limited.

As to the Northwest Territory, Virginia had the right to abolish slavery there; and she did so agree in 1787, with the other States in the Congress of the Confederation, by assenting to and adopting the ordinance of 1787, for the government of the Northwest Territory. She did this also by an act of her Legislature, passed afterwards, which was a treaty in fact.

Before the new Constitution was adopted, she had as much right to treat and agree as any European Government had. And, having excluded slavery, the new Government was bound by that engagement by article six of the new Constitution. This only meant that slavery should not exist whilst the United States exercised the power of government, in the Territorial form; for, when a new State came in, it might do so, with or without slavery.

My opinion is, that Congress had no power, in face of the compact between Virginia and the twelve other States, to force slavery into the Northwest Territory, because there, it was bound to that "engagement," and could not break it.

In 1790, North Carolina ceded her western territory, now the State of Tennessee, and stipulated that the inhabitants thereof should enjoy all the privileges and advantages of the ordinance for governing the territory north of the Ohio river, and that Congress should assume the government, and accept the cession, under the express conditions contained in the ordinance: Provided, "That no regulation made, or to be made, by Congress, shall tend to emancipate slaves."

In 1802, Georgia ceded her western territory to the United States, with the provision that the ordinance of 1787 should in all its parts extend to the territory ceded, "that article only excepted which forbids slavery." Congress had no more power to legislate slavery out from the North Carolina and Georgia cessions, than it had power to legislate slavery in, north of the Ohio. No power existed in Congress to legislate at all, affecting slavery, in either case. The inhabitants, as respected this description of property, stood protected whilst they were governed by Congress, in like manner that they were protected before the cession was made, and when they were, respectively, parts of North Carolina and Georgia.

And how does the power of Congress stand west of the Mississippi river? The country there was acquired from France, by treaty, in 1803. It declares, that the First Consul, in the name of the French Republic, doth hereby cede to the United States, in full sovereignty, the colony or province of Louisiana, with all the rights and appurtenances of the said territory. And, by article third, that "the inhabitants of the ceded territory shall be incorporated in the Union of the United States, and admitted as soon as possible, according to the principles of the Federal Constitution, to the enjoyment of all the rights, advantages, and immunities, of citizens of the United States; and, in the mean time, they shall be maintained and protected in the free enjoyment of their liberty, property, and the religion which they profess."

Louisiana was a province where slavery was not only lawful, but where property in slaves was the most valuable of all personal property. The province was ceded as a unit, with an equal right pertaining to all its inhabitants, in every part thereof, to own slaves. It was, to a great extent, a vacant country, having in it few civilized inhabitants. No one portion of the colony, of a proper size for a State of the Union had a sufficient number of inhabitants to claim admission into the Union. To enable the United States to fulfil the treaty, additional population was indispensable, and obviously desired with anxiety by both sides, so that the whole country should, as soon as possible, become States of the Union. And for this contemplated future population, the treaty as expressly provided as it did for the inhabitants residing in the province when the treaty was made. All these were to be protected "in the mean time;" that is to say, at all times, between the date of the treaty and the time when the portion of the Territory where the inhabitants resided was admitted into the Union as a State.

At the date of the treaty, each inhabitant had the right to the free enjoyment of his property, alike with his liberty and his religion, in every part of Louisiana; the province then being one country, he might go everywhere in it, and carry his liberty, property, and religion, with him, and in which he was to be maintained and protected, until he became a citizen of a State of the Union of the United States. This cannot be denied to the original inhabitants and their descendants. And, if it be true that immigrants were equally protected, it must follow that they can also stand on the treaty.

The settled doctrine in the State courts of Louisiana is, that a French subject coming to the Orleans Territory, after the treaty of 1803 was made, and before Louisiana was admitted into the Union, and being an inhabitant at the time of the admission, became a citizen of the United States by that act; that he was one of the inhabitants contemplated by the third article of the treaty, which referred to all the inhabitants embraced within the new State on its admission.

That this is the true construction, I have no doubt.

If power existed to draw a line at thirty-six degrees thirty minutes north, so Congress had equal power to draw the line on the thirtieth degree—that is, due west from the city of New Orleans—and to declare that north of that line slavery should never exist. Suppose this had been done before 1812, when Louisiana came into the Union, and the question of infraction of the treaty had then been presented on the present assumption of power to prohibit slavery, who doubts what the decision of this court would have been on such an act of Congress; yet, the difference between the supposed line, and that on thirty-six degrees thirty minutes north, is only in the degree of grossness presented by the lower line.

The Missouri compromise line of 1820 was very aggressive; it declared that slavery was abolished forever throughout a country reaching from the Mississippi river to the Pacific ocean, stretching over thirty-two degrees of longitude, and twelve and a half degrees of latitude on its eastern side, sweeping over four-fifths, to say no more, of the original province of Louisiana.

That the United States Government stipulated in favor of the inhabitants to the extent here contended for, has not been seriously denied, as far as I know; but the argument is, that Congress had authority to repeal the third article of the treaty of 1803, in so far as it secured the right to hold slave property, in a portion of the ceded territory, leaving the right to exist in other parts. In other words, that Congress could repeal the third article entirely, at its pleasure. This I deny.

The compacts with North Carolina and Georgia were treaties also, and stood on the same footing of the Louisiana treaty; on the assumption of power to repeal the one, it must have extended to all, and Congress could have excluded the slaveholder of North Carolina from the enjoyment of his lands in the Territory now the State of Tennessee, where the citizens of the mother State were the principal proprietors.

And so in the case of Georgia. Her citizens could have been refused the right to emigrate to the Mississippi or Alabama Territory, unless they left their most valuable and cherished property behind them.

The Constitution was framed in reference to facts then existing or likely to arise: the instrument looked to no theories of Government. In the vigorous debates in the Convention, as reported by Mr. Madison and others, surrounding facts, and the condition and necessities of the country, gave rise to almost every provision; and among those facts, it was prominently true, that Congress dare not be intrusted with power to provide that, if North Carolina or Georgia ceded her western territory, the citizens of the State (in either case) could be prohibited, at the pleasure of Congress, from removing to their lands, then granted to a large extent, in the country likely to be ceded, unless they left their slaves behind. That such an attempt, in the face of a population fresh from the war of the Revolution, and then engaged in war with the great confederacy of Indians, extending from the mouth of the Ohio to the Gulf of Mexico, would end in open revolt, all intelligent men knew.

In view of these facts, let us inquire how the question stands by the terms of the Constitution, aside from the treaty? How it stood in public opinion when the Georgia cession was made, in 1802, is apparent from the fact that no guaranty was required by Georgia of the United States, for the protection of slave property. The Federal Constitution was relied on, to secure the rights of Georgia and her citizens during the Territorial condition of the country. She relied on the indisputable truths, that the States were by the Constitution made equals in political rights, and equals in the right to participate in the common property of all the States united, and held in trust for them. The Constitution having provided that "The citizens of each State shall be entitled to all privileges and immunities of citizens of the several States," the right to enjoy the territory as equals was reserved to the States, and to the citizens of the States, respectively. The cited clause is not that citizens of the United States shall have equal privileges in the Territories, but the citizen of each State shall come there in right of his State, and enjoy the common property. He secures his equality through the equality of his State, by virtue of that great fundamental condition of the Union—the equality of the States.

Congress cannot do indirectly what the Constitution prohibits directly. If the slaveholder is prohibited from going to the Territory with his slaves, who are parts of his family in name and in fact, it will follow that men owning lawful property in their own States, carrying with them the equality of their State to enjoy the common property, may be told, you cannot come here with your slaves, and he will be held out at the border. By this subterfuge, owners of slave property, to the amount of thousand of millions, might be almost as effectually excluded from removing into the Territory of Louisiana north of thirty-six degrees thirty minutes, as if the law declared that owners of slaves, as a class, should be excluded, even if their slaves were left behind.

Just as well might Congress have said to those of the North, you shall not introduce into the territory south of said line your cattle or horses, as the country is already overstocked; nor can you introduce your tools of trade, or machines, as the policy of Congress is to encourage the culture of sugar and cotton south of the line, and so to provide that the Northern people shall manufacture for those of the South, and barter for the staple articles slave labor produces. And thus the Northern farmer and mechanic would be held out, as the slaveholder was for thirty years, by the Missouri restriction.

If Congress could prohibit one species of property, lawful throughout Louisiana when it was acquired, and lawful in the State from whence it was brought, so Congress might exclude any or all property.

The case before us will illustrate the construction contended for. Dr. Emerson was a citizen of Missouri; he had an equal right to go to the Territory with every citizen of other States. This is undeniable, as I suppose. Scott was Dr. Emerson's lawful property in Missouri; he carried his Missouri title with him; and the precise question here is, whether Congress had the power to annul that title. It is idle to say, that if Congress could not defeat the title directly, that it might be done indirectly, by drawing a narrow circle around the slave population of Upper Louisiana, and declaring that if the slave went beyond it, he should be free. Such assumption is mere evasion, and entitled to no consideration. And it is equally idle to contend, that because Congress has express power to regulate commerce among the Indian tribes, and to prohibit intercourse with the Indians, that therefore Dr. Emerson's title might be defeated within the country ceded by the Indians to the United States as early as 1805, and which embraces Fort Snelling. (Am. State Papers, vol. 1, p. 734.) We must meet the question, whether Congress had the power to declare that a citizen of a State, carrying with him his equal rights, secured to him through his State, could be stripped of his goods and slaves, and be deprived of any participation in the common property? If this be the true meaning of the Constitution, equality of rights to enjoy a common country (equal to a thousand miles square) may be cut off by a geographical line, and a great portion of our citizens excluded from it.

Ingenious, indirect evasions of the Constitution have been attempted and defeated heretofore. In the passenger cases, (7 How. R.,) the attempt was made to impose a tax on the masters, crews, and passengers of vessels, the Constitution having prohibited a tax on the vessel itself; but this court held the attempt to be a mere evasion, and pronounced the tax illegal.

I admit that Virginia could, and lawfully did, prohibit slavery northwest of the Ohio, by her charter of cession, and that the territory was taken by the United States with this condition imposed. I also admit that France could, by the treaty of 1803, have prohibited slavery in any part of the ceded territory, and imposed it on the United States as a fundamental condition of the cession, in the mean time, till new States were admitted in the Union.

I concur with Judge Baldwin, that Federal power is exercised over all the territory within the United States, pursuant to the Constitution; and, the conditions of the cession, whether it was a part of the original territory of a State of the Union, or of a foreign State, ceded by deed or treaty; the right of the United States in or over it depends on the contract of cession, which operates to incorporate as well the Territory as its inhabitants into the Union. (Baldwin's Constitutional Views, 84.)

My opinion is, that the third article of the treaty of 1803, ceding Louisiana to the United States, stands protected by the Constitution, and cannot be repealed by Congress.

And, secondly, that the act of 1820, known as the Missouri compromise, violates the most leading feature of the Constitution—a feature on which the Union depends, and which secures to the respective States and their citizens an entire EQUALITY of rights, privileges, and immunities.

On these grounds, I hold the compromise act to have been void; and, consequently, that the plaintiff, Scott, can claim no benefit under it.

For the reasons above stated, I concur with my brother judges that the plaintiff, Scott, is a slave, and was so when this suit was brought.

Mr. Justice McLEAN dissenting.

This case is before us on a writ of error from the Circuit Court for the district of Missouri.

An action of trespass was brought, which charges the defendant with an assault and imprisonment of the plaintiff, and also of Harriet Scott, his wife, Eliza and Lizzie, his two children, on the ground that they were his slaves, which was without right on his part, and against law.

The defendant filed a plea in abatement, "that said causes of action, and each and every of them, if any such accrued to the said Dred Scott, accrued out of the jurisdiction of this court, and exclusively within the jurisdiction of the courts of the State of Missouri, for that to wit, said plaintiff, Dred Scott, is not a citizen of the State of Missouri, as alleged in his 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; and this the said Sandford is ready to verify; wherefore he prays judgment whether the court can or will take further cognizance of the action aforesaid."

To this a demurrer was filed, which, on argument, was sustained by the court, the plea in abatement being held insufficient; the defendant was ruled to plead over. Under this rule he pleaded: 1. Not guilty; 2. That Dred Scott was a negro slave, the property of the defendant; and 3. That Harriet, the wife, and Eliza and Lizzie, the daughters of the plaintiff, were the lawful slaves of the defendant.

Issue was joined on the first plea, and replications of de injuria were filed to the other pleas.

The parties agreed to the following facts: In the year 1834, the plaintiff was a negro slave belonging to Dr. Emerson, who was a surgeon in the army of the United States. In that year, Dr. Emerson took the plaintiff from the State of Missouri to the post of Rock Island, in the State of Illinois, and held him there as a slave until the month of April or May, 1836. At the time last mentioned, Dr. Emerson removed the plaintiff from Rock Island to the military post at Fort Snelling, situate on the west bank of the Mississippi river, in the territory known as Upper Louisiana, acquired by the United States of France, and situate north of latitude thirty-six degrees thirty minutes north, and north of the State of Missouri. Dr. Emerson held the plaintiff in slavery, at Fort Snelling, from the last-mentioned date until the year 1838.

In the year 1835, Harriet, who is named in the second count of the plaintiff's declaration, was the negro slave of Major Taliaferro, who belonged to the army of the United States. In that year, Major Taliaferro took Harriet to Fort Snelling, a military post situated as hereinbefore stated, and kept her there as a slave until the year 1836, and then sold and delivered her as a slave, at Fort Snelling, unto Dr. Emerson, who held her in slavery, at that place, until the year 1838.

In the year 1836, the plaintiff and Harriet were married at Fort Snelling, with the consent of Dr. Emerson, who claimed to be their master and owner. Eliza and Lizzie, named in the third count of the plaintiff's declaration, are the fruit of that marriage. Eliza is about fourteen years old, and was born on board the steamboat Gipsey, north of the north line of the State of Missouri, and upon the river Mississippi. Lizzie is about seven years old, and was born in the State of Missouri, at the military post called Jefferson Barracks.

In the year 1838, Dr. Emerson removed the plaintiff and said Harriet and their daughter Eliza from Fort Snelling to the State of Missouri, where they have ever since resided.

Before the commencement of the suit, Dr. Emerson sold and conveyed the plaintiff, Harriet, Eliza, and Lizzie, to the defendant, as slaves, and he has ever since claimed to hold them as slaves.

At the times mentioned in the plaintiff's declaration, the defendant, claiming to be the owner, laid his hands upon said plaintiff, Harriet, Eliza, and Lizzie, and imprisoned them; doing in this respect, however, no more than he might lawfully do, if they were of right his slaves at such times.

In the first place, the plea to the jurisdiction is not before us, on this writ of error. A demurrer to the plea was sustained, which ruled the plea bad, and the defendant, on leave, pleaded over.

The decision on the demurrer was in favor of the plaintiff; and as the plaintiff prosecutes this writ of error, he does not complain of the decision on the demurrer. The defendant might have complained of this decision, as against him, and have prosecuted a writ of error, to reverse it. But as the case, under the instruction of the court to the jury, was decided in his favor, of course he had no ground of complaint.

But it is said, if the court, on looking at the record, shall clearly perceive that the Circuit Court had no jurisdiction, it is a ground for the dismissal of the case. This may be characterized as rather a sharp practice, and one which seldom, if ever, occurs. No case was cited in the argument as authority, and not a single case precisely in point is recollected in our reports. The pleadings do not show a want of jurisdiction. This want of jurisdiction can only be ascertained by a judgment on the demurrer to the special plea. No such case, it is believed, can be cited. But if this rule of practice is to be applied in this case, and the plaintiff in error is required to answer and maintain as well the points ruled in his favor, as to show the error of those ruled against him, he has more than an ordinary duty to perform. Under such circumstances, the want of jurisdiction in the Circuit Court must be so clear as not to admit of doubt. Now, the plea which raises the question of jurisdiction, in my judgment, is radically defective. The gravamen of the plea is this: "That the plaintiff is a negro of African descent, his ancestors being of pure African blood, and were brought into this country, and sold as negro slaves."

There is no averment in this plea which shows or conduces to show an inability in the plaintiff to sue in the Circuit Court. It does not allege that the plaintiff had his domicil in any other State, nor that he is not a free man in Missouri. He is averred to have had a negro ancestry, but this does not show that he is not a citizen of Missouri, within the meaning of the act of Congress authorizing him to sue in the Circuit Court. It has never been held necessary, to constitute a citizen within the act, that he should have the qualifications of an elector. Females and minors may sue in the Federal courts, and so may any individual who has a permanent domicil in the State under whose laws his rights are protected, and to which he owes allegiance.

Being born under our Constitution and laws, no naturalization is required, as one of foreign birth, to make him a citizen. The most general and appropriate definition of the term citizen is "a freeman." Being a freeman, and having his domicil in a State different from that of the defendant, he is a citizen within the act of Congress, and the courts of the Union are open to him.

It has often been held, that the jurisdiction, as regards parties, can only be exercised between citizens of different States, and that a mere residence is not sufficient; but this has been said to distinguish a temporary from a permanent residence.

To constitute a good plea to the jurisdiction, it must negative those qualities and rights which enable an individual to sue in the Federal courts. This has not been done; and on this ground the plea was defective, and the demurrer was properly sustained. No implication can aid a plea in abatement or in bar; it must be complete in itself; the facts stated, if true, must abate or bar the right of the plaintiff to sue. This is not the character of the above plea. The facts stated, if admitted, are not inconsistent with other facts, which may be presumed, and which bring the plaintiff within the act of Congress.

The pleader has not the boldness to allege that this plaintiff is a slave, as that would assume against him the matter in controversy, and embrace the entire merits of the case in a plea to the jurisdiction. But beyond the facts set out in the plea, the court, to sustain it, must assume the plaintiff to be a slave, which is decisive on the merits. This is a short and an effectual mode of deciding the cause; but I am yet to learn that it is sanctioned by any known rule of pleading.

The defendant's counsel complain, that if the court take jurisdiction on the ground that the plaintiff is free, the assumption is against the right of the master. This argument is easily answered. In the first place, the plea does not show him to be a slave; it does not follow that a man is not free whose ancestors were slaves. The reports of the Supreme Court of Missouri show that this assumption has many exceptions; and there is no averment in the plea that the plaintiff is not within them.

By all the rules of pleading, this is a fatal defect in the plea. If there be doubt, what rule of construction has been established in the slave States? In Jacob v. Sharp, (Meigs's Rep., Tennessee, 114,) the court held, when there was doubt as to the construction of a will which emancipated a slave, "it must be construed to be subordinate to the higher and more important right of freedom."

No injustice can result to the master, from an exercise of jurisdiction in this cause. Such a decision does not in any degree affect the merits of the case; it only enables the plaintiff to assert his claims to freedom before this tribunal. If the jurisdiction be ruled against him, on the ground that he is a slave, it is decisive of his fate.

It has been argued that, if a colored person be made a citizen of a State, he cannot sue in the Federal court. The Constitution declares that Federal jurisdiction "may be exercised between citizens of different States," and the same is provided in the act of 1789. The above argument is properly met by saying that the Constitution was intended to be a practical instrument; and where its language is too plain to be misunderstood, the argument ends.

In Chirae v. Chirae, (2 Wheat., 261; 4 Curtis, 99,) this court says: "That the power of naturalization is exclusively in Congress does not seem to be, and certainly ought not to be, controverted." No person can legally be made a citizen of a State, and consequently a citizen of the United States, of foreign birth, unless he be naturalized under the acts of Congress. Congress has power "to establish a uniform rule of naturalization."

It is a power which belongs exclusively to Congress, as intimately connected with our Federal relations. A State may authorize foreigners to hold real estate within its jurisdiction, but it has no power to naturalize foreigners, and give them the rights of citizens. Such a right is opposed to the acts of Congress on the subject of naturalization, and subversive of the Federal powers. I regret that any countenance should be given from this bench to a practice like this in some of the States, which has no warrant in the Constitution.

In the argument, it was said that a colored citizen would not be an agreeable member of society. This is more a matter of taste than of law. Several of the States have admitted persons of color to the right of suffrage, and in this view have recognised them as citizens; and this has been done in the slave as well as the free States. On the question of citizenship, it must be admitted that we have not been very fastidious. Under the late treaty with Mexico, we have made citizens of all grades, combinations, and colors. The same was done in the admission of Louisiana and Florida. No one ever doubted, and no court ever held, that the people of these Territories did not become citizens under the treaty. They have exercised all the rights of citizens, without being naturalized under the acts of Congress.

There are several important principles involved in this case, which have been argued, and which may be considered under the following heads:

1. The locality of slavery, as settled by this court and the courts of the States.

2. The relation which the Federal Government bears to slavery in the States.

3. The power of Congress to establish Territorial Governments, and to prohibit the introduction of slavery therein.

4. The effect of taking slaves into a new State or Territory, and so holding them, where slavery is prohibited.

5. Whether the return of a slave under the control of his master, after being entitled to his freedom, reduces him to his former condition.

6. Are the decisions of the Supreme Court of Missouri, on the questions before us, binding on this court, within the rule adopted.

In the course of my judicial duties, I have had occasion to consider and decide several of the above points.

1. As to the locality of slavery. The civil law throughout the Continent of Europe, it is believed, without an exception, is, that slavery can exist only within the territory where it is established; and that, if a slave escapes, or is carried beyond such territory, his master cannot reclaim him, unless by virtue of some express stipulation. (Grotius, lib. 2, chap. 15, 5, 1; lib. 10, chap. 10, 2, 1; Wicqueposts Ambassador, lib. 1, p. 418; 4 Martin, 385; Case of the Creole in the House of Lords, 1842; 1 Phillimore on International Law, 316, 335.)

There is no nation in Europe which considers itself bound to return to his master a fugitive slave, under the civil law or the law of nations. On the contrary, the slave is held to be free where there is no treaty obligation, or compact in some other form, to return him to his master. The Roman law did not allow freedom to be sold. An ambassador or any other public functionary could not take a slave to France, Spain, or any other country of Europe, without emancipating him. A number of slaves escaped from a Florida plantation, and were received on board of ship by Admiral Cochrane; by the King's Bench, they were held to be free. (2 Barn. and Cres., 440.)

In the great and leading case of Prigg v. The State of Pennsylvania, (16 Peters, 594; 14 Curtis, 421,) this court say that, by the general law of nations, no nation is bound to recognise the state of slavery, as found within its territorial dominions, where it is in opposition to its own policy and institutions, in favor of the subjects of other nations where slavery is organized. If it does it, it is as a matter of comity, and not as a matter of international right. The state of slavery is deemed to be a mere municipal regulation, founded upon and limited to the range of the territorial laws. This was fully recognised in Somersett's case, (Lafft's Rep., 1; 20 Howell's State Trials, 79,) which was decided before the American Revolution.

There was some contrariety of opinion among the judges on certain points ruled in Prigg's case, but there was none in regard to the great principle, that slavery is limited to the range of the laws under which it is sanctioned.

No case in England appears to have been more thoroughly examined than that of Somersett. The judgment pronounced by Lord Mansfield was the judgment of the Court of King's Bench. The cause was argued at great length, and with great ability, by Hargrave and others, who stood among the most eminent counsel in England. It was held under advisement from term to term, and a due sense of its importance was felt and expressed by the Bench.
