• Dred Scott v. Sanford (1857)

Mr. Chief Justice TANEY delivered the opinion of the court.

…There are two leading questions presented by the record: 1. Had the Circuit Court of the United States jurisdiction to hear and determine the case between these parties? And 2. If it had jurisdiction, is the judgment it has given erroneous or not?

….Before we speak of the pleas in bar, it will be proper to dispose of the questions which have arisen on the plea in abatement. That plea denies the right of the plaintiff to sue in a court of the United States, for the reasons therein stated. If the question raised by it is legally before us, and the court should be of opinion that the facts stated in it disqualify the plaintiff from becoming a citizen, in the sense in which that word is used in the Constitution of the United States, then the judgment of the Circuit Court is erroneous, and must be reversed….

[A]lthough the United States is sovereign and supreme in its appropriate sphere of action, yet it does not possess all the powers which usually belong to the sovereignty of a nation. Certain specified powers, enumerated in the Constitution, have been conferred upon it; and neither the legislative, executive, nor judicial departments of the Government can lawfully exercise any authority beyond the limits marked out by the Constitution. And in regulating the judicial department, the cases in which the courts of the United States shall have jurisdiction are particularly and specifically enumerated and defined; and they are not authorized to take cognizance of any case which does not come within the description therein specified. Hence, when a plaintiff sues in a court of the United States, it is necessary that he should show, in his pleading, that the suit he brings is within the jurisdiction of the court, and that he is entitled to sue there. And if he omits to do this, and should, by any oversight of the Circuit Court, obtain a judgment in his favor, the judgment would be reversed in the appellate court for want of jurisdiction in the court below….

It becomes, therefore, our duty to decide whether the facts stated in the plea are or are not sufficient to show that the plaintiff is not entitled to sue as a citizen in a court of the United States.

This is certainly a very serious question, and one that now for the first time has been brought for decision before this court. But it is brought here by those who have a right to bring it, and it is our duty to meet it and decide it.

The question is simply this: Can a negro, whose ancestors were imported into this country, and sold as slaves, become a member of the political community formed and brought into existence by the Constitution of the United States, and as such become entitled to all the rights, and privileges, and immunities, guarantied by that instrument to the citizen? One of which rights is the privilege of suing in a court of the United States in the cases specified in the Constitution.

It will be observed, that the plea applies to that class of persons only whose ancestors were negroes of the African race, and imported into this country, and sold and held as slaves. The only matter in issue before the court, therefore, is, whether the descendants of such slaves, when they shall be emancipated, or who are born of parents who had become free before their birth, are citizens of a State, in the sense in which the word citizen is used in the Constitution of the United States. And this being the only matter in dispute on the pleadings, the court must be understood as speaking in this opinion of that class only, that is, of those persons who are the descendants of Africans who were imported into this country, and sold as slaves.

…We proceed to examine the case as presented by the pleadings.

The words ‘people of the United States’ and ‘citizens’ are synonymous terms, and mean the same thing. They both describe the political body who, according to our republican institutions, form the sovereignty, and who hold the power and conduct the Government through their representatives. They are what we familiarly call the ‘sovereign people,’ and every citizen is one of this people, and a constituent member of this sovereignty. The question before us is, whether the class of persons described in the plea in abatement compose a portion of this people, and are constituent members of this sovereignty? We think they are not, and that they are not included, and were not intended to be included, under the word ‘citizens’ in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States. On the contrary, they were at that time considered as a subordinate and inferior class of beings, who had been subjugated by the dominant race, and, whether emancipated or not, yet remained subject to their authority, and had no rights or privileges but such as those who held the power and the Government might choose to grant them.

It is not the province of the court to decide upon the justice or injustice, the policy or impolicy, of these laws. The decision of that question belonged to the political or law-making power; to those who formed the sovereignty and framed the Constitution. The duty of the court is, to interpret the instrument they have framed, with the best lights we can obtain on the subject, and to administer it as we find it, according to its true intent and meaning when it was adopted.

…The question then arises, whether the provisions of the Constitution, in relation to the personal rights and privileges to which the citizen of a State should be entitled, embraced the negro African race, at that time in this country, or who might afterwards be imported, who had then or should afterwards be made free in any State; and to put it in the power of a single State to make him a citizen of the United States, and endue him with the full rights of citizenship in every other State without their consent? Does the Constitution of the United States act upon him whenever he shall be made free under the laws of a State, and raised there to the rank of a citizen, and immediately clothe him with all the privileges of a citizen in every other State, and in its own courts?

The court think the affirmative of these propositions cannot be maintained. And if it cannot, the plaintiff in error could not be a citizen of the State of Missouri, within the meaning of the Constitution of the United States, and, consequently, was not entitled to sue in its courts.

It is true, every person, and every class and description of persons, who were at the time of the adoption of the Constitution recognised as citizens in the several States, became also citizens of this new political body; but none other; it was formed by them, and for them and their posterity, but for no one else. And the personal rights and privileges guarantied to citizens of this new sovereignty were intended to embrace those only who were then members of the several State communities, or who should afterwards by birthright or otherwise become members, according to the provisions of the Constitution and the principles on which it was founded. It was the union of those who were at that time members of distinct and separate political communities into one political family, whose power, for certain specified purposes, was to extend over the whole territory of the United States. And it gave to each citizen rights and privileges outside of his State  which he did not before possess, and placed him in every other State upon a perfect equality with its own citizens as to rights of person and rights of property; it made him a citizen of the United States.

It becomes necessary, therefore, to determine who were citizens of the several States when the Constitution was adopted. And in order to do this, we must recur to the Governments and institutions of the thirteen colonies, when they separated from Great Britain and formed new sovereignties, and took their places in the family of independent nations. We must inquire who, at that time, were recognised as the people or citizens of a State, whose rights and liberties had been outraged by the English Government; and who declared their independence, and assumed the powers of Government to defend their rights by force of arms.

In the opinion of the court, the legislation and histories of the times, and the language used in the Declaration of Independence, show, that neither the class of persons who had been imported as slaves, nor their descendants, whether they had become free or not, were then acknowledged as a part of the people, nor intended to be included in the general words used in that memorable instrument.

There are two clauses in the Constitution which point directly and specifically to the negro race as a separate class of persons, and show clearly that they were not regarded as a portion of the people or citizens of the Government then formed.

One of these clauses reserves to each of the thirteen States the right to import slaves until the year 1808, if it thinks proper. And the importation which it thus sanctions was unquestionably of persons of the race of which we are speaking, as the traffic in slaves in the United States had always been confined to them. And by the other provision the States pledge themselves to each other to maintain the right of property of the master, by delivering up to him any slave who may have escaped from his service, and be found within their respective territories. By the first above-mentioned clause, therefore, the right to purchase and hold this property is directly sanctioned and authorized for twenty years by the people who framed the Constitution. And by the second, they pledge themselves to maintain and uphold the right of the master in the manner specified, as long as the Government they then formed should endure. And these two provisions show, conclusively, that neither the description of persons therein referred to, nor their descendants, were embraced in any of the other provisions of the Constitution; for certainly these two clauses were not intended to confer on them or their posterity the blessings of liberty, or any of the personal rights so carefully provided for the citizen.

No one of that race had ever migrated to the United States voluntarily; all of them had been brought here as articles of merchandise. The number that had been emancipated at that time were but few in comparison with those held in slavery; and they were identified in the public mind with the race to which they belonged, and regarded as a part of the slave population rather than the free. It is obvious that they were not even in the minds of the framers of the Constitution when they were conferring special rights and privileges upon the citizens of a State in every other part of the Union.

Indeed, when we look to the condition of this race in the several States at the time, it is impossible to believe that these rights and privileges were intended to be extended to them….

Undoubtedly, a person may be a citizen, that is, a member of the community who form the sovereignty, although he exercises no share of the political power, and is incapacitated from holding particular offices. Women and minors, who form a part of the political family, cannot vote; and when a property qualification is required to vote or hold a particular office, those who have not the necessary qualification cannot vote or hold the office, yet they are citizens.

So, too, a person may be entitled to vote by the law of the State, who is not a citizen even of the State itself. And in some of the States of the Union foreigners not naturalized are allowed to vote. And the State may give the right to free negroes and mulattoes, but that does not make them citizens of the State, and still less of the United States. And the provision in the Constitution giving privileges and immunities in other States, does not apply to them….

The only two provisions which point to them and include them, treat them as property, and make it the duty of the Government to protect it; no other power, in relation to this race, is to be found in the Constitution; and as it is a Government of special, delegated, powers, no authority beyond these two provisions can be constitutionally exercised. The Government of the United States had no right to interfere for any other purpose but that of protecting the rights of the owner, leaving it altogether with the several States to deal with this race, whether emancipated or not, as each State may think justice, humanity, and the interests and safety of society, require. The States evidently intended to reserve this power exclusively to themselves.

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

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

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

Whether, therefore, we take the particular clause in question, by itself, or in connection with the other provisions of the Constitution, we think it clear, that it applies only to the particular territory of which we have spoken, and cannot, by any just rule of interpretation, be extended to territory which the new Government might afterwards obtain from a foreign nation. Consequently, the power which Congress may have lawfully exercised in this Territory, while it remained under a Territorial Government, and which may have been sanctioned by judicial decision, can furnish no justification and no argument to support a similar exercise of power over territory afterwards acquired by the Federal Government. We put aside, therefore, any argument, drawn from precedents, showing the extent of the power which the General Government exercised over slavery in this Territory, as altogether inapplicable to the case before us…..

This brings us to examine by what provision of the Constitution the present Federal Government, under its delegated and restricted powers, is authorized to acquire territory outside of the original limits of the United States, and what powers it may exercise therein over the person or property of a citizen of the United States, while it remains a Territory, and until it shall be admitted as one of the States of the Union.

There is certainly no power given by the Constitution to the Federal Government to establish or maintain colonies bordering on the United States or at a distance, to be ruled and governed at its own pleasure; nor to enlarge its territorial limits in any way, except by the admission of new States. That power is plainly given; and if a new State is admitted, it needs no further legislation by Congress, because the Constitution itself defines the relative rights and powers, and duties of the State, and the citizens of the State, and the Federal Government. But no power is given to acquire a Territory to be held and governed permanently in that character….

All we mean to say on this point is, that, as there is no express regulation in the Constitution defining the power which the General Government may exercise over the person or property of a citizen in a Territory thus acquired, the court must necessarily look to the provisions and principles of the Constitution, and its distribution of powers, for the rules and principles by which its decision must be governed….

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

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

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

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

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

So, too, it will hardly be contended that Congress could by law quarter a soldier in a house in a Territory without the consent of the owner, in time of peace; nor in time of war, but in a manner prescribed by law. Nor could they by law forfeit the property of a citizen in a Territory who was convicted of treason, for a longer period than the life of the person convicted; nor take private property for public use without just compensation.

The powers over person and property of which we speak are not only not granted to Congress, but are in express terms denied, and they are forbidden to exercise them. And this prohibition is not confined to the States, but the words are general, and extend to the whole territory over which the Constitution gives it power to legislate, including those portions of it remaining under Territorial Government, as well as that covered by States. It is a total absence of power everywhere within the dominion of the United States, and places the citizens of a Territory, so far as these rights areconcerned, on the same footing with citizens of the States, and guards them as firmly and plainly against any inroads which the General Government might attempt, under the plea of implied or incidental powers. And if Congress itself cannot do this-if it is beyond the powers conferred on the Federal Government-it will be admitted, we presume, that it could not authorize a Territorial Government to exercise them. It could confer no power on any local Government, established by its authority, to violate the provisions of the Constitution.

It seems, however, to be supposed, that there is a difference between property in a slave and other property, and that different rules may be applied to it in expounding the Constitution of the United States. And the laws and usages of nations, and the writings of eminent jurists upon the relation of master and slave and their mutual rights and duties, and the powers which Governments may exercise over it, have been dwelt upon in the argument.

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

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

Upon the whole, therefore, it is the judgment of this court, that it appears by the record before us that the plaintiff in error is not a citizen of Missouri, in the sense in which that word is used in the Constitution; and that the Circuit Court of the United States, for that reason, had no jurisdiction in the case, and could give no judgment in it. Its judgment for the defendant must, consequently, be reversed, and a mandate issued, directing the suit to be dismissed for want of jurisdiction.

Mr. Justice McLEAN and Mr. Justice CURTIS dissented.

Mr. Justice McLEAN dissenting.

….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….

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….

I will now consider the relation which the Federal Government bears to slavery in the States:

Slavery is emphatically a State institution. In the ninth section of the first article of the Constitution, it is provided ‘that the migration or importation of such persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the year 1808, but a tax or duty may be imposed on such importation, not exceeding ten dollars for each person.’

In the Convention, it was proposed by a committee of eleven to limit the importation of slaves to the year 1800, when Mr. Pinckney moved to extend the time to the year 1808. This motion was carried-New Hampshire, Massachusetts, Connecticut, Maryland, North Carolina, South Carolina, and Georgia, voting in the affirmative; and New Jersey, Pennsylvania, and Virginia, in the negative. In opposition to the motion, Mr. Madison said: ‘Twenty years will produce all the mischief that can be apprehended from the liberty to import slaves; so long a term will be more dishonorable to the American character than to say nothing about it in the Constitution.’

The provision in regard to the slave trade shows clearly that Congress considered slavery a State institution, to be continued and regulated by its individual sovereignty; and to conciliate that interest, the slave trade was continued twenty years, not as a general measure, but for the ‘benefit of such States as shall think proper to encourage it….’

The only connection which the Federal Government holds with slaves in a State, arises from that provision of the Constitution which declares that ‘No person held to service or labor in one State, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor, but shall be delivered up, on claim of the party to whom such service or labor may be due.’

This being a fundamental law of the Federal Government, it rests mainly for its execution, as has been held, on the judicial power of the Union; and so far as the rendition of fugitives from labor has become a subject of judicial action, the Federal obligation has been faithfully discharged.

In the formation of the Federal Constitution, care was taken to confer no power on the Federal Government to interfere with this institution in the States. In the provision respecting the slave trade, in fixing the ratio of representation, and providing for the reclamation of fugitives from labor, slaves were referred to as persons, and in no other respect are they considered in the Constitution.

We need not refer to the mercenary spirit which introduced the infamous traffic in slaves, to show the degradation of negro slavery in our country. This system was imposed upon our colonial settlements by the mother country, and it is due to truth to say that the commercial colonies and States were chiefly engaged in the traffic. But we know as a historical fact, that James Madison, that great and good man, a leading member in the Federal Convention, was solicitous to guard the language of that instrument so as not to convey the idea that there could be property in man.

I prefer the lights of Madison, Hamilton, and Jay, as a means of construing the Constitution in all its bearings, rather than to look behind that period, into a traffic which is now declared to be piracy, and punished with death by Christian nations. I do not like to draw the sources of our domestic relations from so dark a ground. Our independence was a great epoch in the history of freedom; and while I admit the Government was not made expecially for the colored race, yet many of them were citizens of the New England States, and exercised, the rights of suffrage when the Constitution was adopted, and it was not doubted by any intelligent person that its tendencies would greatly ameliorate their condition.

Many of the States, on the adoption of the Constitution, or shortly afterward, took measures to abolish slavery within their respective jurisdictions; and it is a well-known fact that a belief was cherished by the leading men, South as well as North, that the institution of slavery would gradually decline, until it would become extinct. The increased value of slave labor, in the culture of cotton and sugar, prevented the realization of this expectation. Like all other communities and States, the South were influenced by what they considered to be their own interests.

But if we are to turn our attention to the dark ages of the world, why confine our view to colored slavery? On the same principles, white men were made slaves. All slavery has its origin in power, and is against right.

The power of Congress to establish Territorial Governments, and to prohibit the introduction of slavery therein, is the next point to be considered….

The sovereignty of the Federal Government extends to the entire limits of our territory. Should any foreign power invade our jurisdiction, it would be repelled. There is a law of Congress to punish our citizens for crimes committed in districts of country where there is no organized Government. Criminals are brought to certain Territories or States, designated in the law, for punishment. Death has been inflicted in Arkansas and in Missouri, on individuals, for murders committed beyond the limit of any organized Territory or State; and no one doubts that such a jurisdiction was rightfully exercised. If there be a right to acquire territory, there necessarily must be an implied power to govern it. When the military force of the Union shall conquer a country, may not Congress provide for the government of such country? This would be an implied power essential to the acquisition of new territory.  This power has been exercised, without doubt of its constitutionality, over territory acquired by conquest and purchase.

And when there is a large district of country within the United States, and not within any State Government, if it be necessary to establish a temporary Government to carry out a power expressly vested in Congress-as the disposition of the public lands-may not such Government be instituted by Congress? How do we read the Constitution? Is it not a practical instrument?…

The prohibition of slavery north of thirty-six degrees thirty minutes, and of the State of Missouri, contained in the act admitting that State into the Union, was passed by a vote of 134, in the House of Representatives, to 42. Before Mr. Monroe signed the act, it was submitted by him to his Cabinet, and they held the restriction of slavery in a Territory to be within the constitutional powers of Congress. It would be singular, if in 1804 Congress had power to prohibit the introduction of slaves in Orleans Territory from any other part of the Union, under the penalty of freedom to the slave, if the same power, embodied in the Missouri compromise, could not be exercised in 1820.

But this law of Congress, which prohibits slavery north of  Missouri and of thirty-six degrees thirty minutes, is declared to have been null and void by my brethren. And this opinion is founded mainly, as I understand, on the distinction drawn between the ordinance of 1787 and the Missouri compromise line. In what does the distinction consist?…

When Dred Scott, his wife and children, were removed from Fort Snelling to Missouri, in 1838, they were free, as the law was then settled, and continued for fourteen years afterwards, up to 1852, when the above decision was made. Prior to this, for nearly thirty years, as Chief Justice Gamble declares, the residence of a master with his slave in the State of Illinois, or in the Territory north of Missouri, where slavery was prohibited by the act called the Missouri compromise, would manumit the slave as effectually as if he had executed a deed of emancipation; and that an officer of the army who takes his slave into that State or Territory, and holds him there as a slave, liberates him the same as any other citizen- and down to the above time it was settled by numerous and uniform decisions, and that on the return of the slave to Missouri, his former condition of slavery did not attach. Such was the settled law of Missouri until the decision of Scott and Emerson….

But there is no pretence that the case of Dred Scott v. Emerson turned upon the construction of a Missouri statute; nor was there any established rule of property which could have rightfully influenced the decision. On the contrary, the decision overruled the settled law for near thirty years.

This is said by my brethren to be a Missouri question; but there is nothing which gives it this character, except that it involves the right to persons claimed as slaves who reside in Missouri, and the decision was made by the Supreme Court of that State. It involves a right claimed under an act of Congress and the Constitution of Illinois, and which cannot be decided without the consideration and construction of those laws. But the Supreme Court of Missouri held, in this case, that it will not regard either of those laws, without which there was no case before it; and Dred Scott, having been a slave, remains a slave. In this respect it is admitted this is a Missouri question-a case which has but one side, if the act of Congress and the Constitution of Illinois are not recognised….

But there is another ground which I deem conclusive, and which I will re-state.

The Supreme Court of Missouri refused to notice the act of Congress or the Constitution of Illinois, under which Dred Scott, his wife and children, claimed that they are entitled to freedom.

This being rejected by the Missouri court, there was no case before it, or least it was a case with only one side. And this is the case which, in the opinion of this court, we are bound to follow. The Missouri court disregards the express provisions of an act of Congress and the Constitution of a sovereign State, both of which laws for twenty-eight years it had not only regarded, but carried into effect.

If a State court may do this, on a question involving the liberty of a human being, what protection do the laws afford? So far from this being a Missouri question, it is a question, as it would seem, within the twenty- fifth section of the judiciary act, where a right to freedom being set up under the act of Congress, and the decision being against such right, it may be brought for revision before this court, from the Supreme Court of Missouri. I think the judgment of the court below should be reversed.

Mr. Justice CURTIS dissenting….

….If it can be shown, by anything in the Constitution itself, that when it confers on Congress the power to make all needful rules and regulations respecting the territory belonging to the United States, the exclusion or the allowance of slavery was excepted; or if anything in the history of this provision tends to show that such an exception was intended by those who framed and adopted the Constitution to be introduced into it, I hold it to be my duty carefully to consider, and to allow just weight to such considerations in interpreting the positive text of the Constitution. But where the Constitution has said all needful rules and regulations, I must find something more than theoretical reasoning to induce me to say it did not mean all….

For these reasons, I am of opinion that so much of the several acts of Congress as prohibited slavery and involuntary servitude within that part of the Territory of Wisconsin lying north of thirty-six degrees thirty minutes north latitude, and west of the river Mississippi, were constitutional and valid laws.
