"The second is drawn from considerations equally general, concerning the right of self-government, and the nature of the political institutions which have been established by the people of the United States.

"While the third is said to rest upon the equal right of all citizens to go with their property upon the public domain, and the inequality of a regulation which would admit the property of some and exclude the property of other citizens; and, inasmuch as slaves are chiefly held by citizens of those particular States where slavery is established, it is insisted that a regulation excluding slavery from a Territory operates, practically, to make an unjust discrimination between citizens of different States, in respect to their use and enjoyment of the territory of the United States.

"With the weight of either of these considerations, when presented to Congress to influence its action, this court has no concern. One or the other may be justly entitled to guide or control the legislative judgment upon what is a needful regulation. The question here is, whether they are sufficient to authorize this court to insert into this clause of the Constitution an exception of the exclusion or allowance of slavery, not found therein, nor in any other part of that instrument. To ingraft on any instrument a substantive exception not found in it, must be admitted to be a matter attended with great difficulty. And the difficulty increases with the importance of the instrument and the magnitude and complexity of the interests involved in its construction. To allow this to be done with the Constitution, upon reasons purely political, renders its judicial interpretation impossible-because judicial tribunals, as such, cannot decide upon political considerations. Political reasons have not the requisite certainty to afford rules of juridical interpretation. They are different in different men. They are different in the same men at different times. And when a strict interpretation of the Constitution, according to the fixed rules which govern the interpretation of laws, is abandoned, and the theoretical opinions of individuals are allowed to control its meaning, we have no longer a Constitution; we are under the government of indi

vidual men, who, for the time being, have power to declare what the Constitution is, according to their own views of what it ought to mean. When such a method of interpretation of the Constitution obtains, in place of a republican Government, with limited and defined powers, we have a Government which is merely an exponent of the will of Congress; or what, in my opinion, would not be preferable, an exponent of the individual political opinions of the members of this court.

"If it can be shown, by any thing 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 any thing 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.

"There have been eminent instances in this court closely analogous to this one, in which such an attempt to introduce an exception, not found in the Constitution itself, has failed of success."

After referring to settled constructions of the grant to Congress of power of exclusive legislation in all cases whatsoever within the District of Columbia, and power to regulate commerce with foreign nations,-Judge Curtis, on page 623, proceeds to say:

"While the regulation is one 'respecting the territory,' while it is, in the judgment of Congress, 'a needful regulation,' and is thus completely within the words of the grant, while no other clause of the Constitution can be shown, which requires the insertion of an exception respecting slavery, and while the practical construction for a period of upwards of fifty years forbids such an exception, it would, in my opinion, violate every sound rule of interpretation to force that exception into the Constitution upon

the strength of abstract political reasoning, which we are bound to believe the people of the United States thought insufficient to induce them to limit the power of Congress, because what they have said contains no such limitation.

"Before I proceed further to notice some other grounds of supposed objection to this power of Congress, I desire to say, that if it were not for my anxiety to insist upon what I deem a correct exposition of the Constitution, if I looked only to the purposes of the argument, the source of the power of Congress asserted in the opinion of the majority of the court would answer those purposes equally well. For they admit that Congress has power to organize and govern the Territories until they arrive at a suitable condition for admission to the Union; they admit, also, that the kind of Government which shall thus exist should be regulated by the condition and wants of each Territory, and that it is necessarily committed to the discretion of Congress to enact such laws for that purpose as that discretion may dictate; and no limit to that discretion has been shown, or even suggested, save those positive prohibitions to legislate, which are found in the Constitution.

"I confess myself unable to perceive any difference whatever between my own opinion of the general extent of the power of Congress and the opinion of the majority of the court, save that I consider it derivable from the express language of the Constitution, while they hold it to be silently implied from the power to acquire territory. Looking at the power of Congress over the Territories as of the extent just described, what positive prohibition exists in the Constitution, which restrained Congress from enacting a law in 1820 to prohibit slavery north of thirtysix degrees thirty minutes north latitude ?

"The only one suggested is that clause in the fifth article of the amendments of the Constitution which declares that no person shall be deprived of his life, liberty, or property, without due process of law. I will now proceed to examine the question, whether this clause is entitled to the effect thus attributed to it. It is necessary, first, to have a clear view of the nature and incidents of that particular species of property which is now in question.

"Slavery, being contrary to natural right, is created only by municipal law. This is not only plain in itself, and agreed by all writers on the subject, but is inferable from the Constitution, and has been explicitly declared by this court. The Constitution refers to slaves as 'persons held to service in one State, under the laws thereof.' Nothing can more clearly describe a status created by municipal law. In Prigg v. Pennsylvania, (16 Pet. 611,) this court said: "The state of slavery is deemed to be a mere municipal regulation, founded on and limited to the range of territorial laws. In Rankin v. Lydia, (2 Marsh. 12, 470,) the Supreme Court of Appeals of Kentucky, said: 'Slavery is sanctioned by the laws of this State, and the right to hold them under our municipal regulations is unquestionable. But we view this as a right existing by positive law of a municipal character, without foundation in the law of nature or the unwritten common law.' I am not acquainted with any case or writer questioning the correctness of this doctrine. (See also 1 Burge, Col. and For. Laws, 738-741, where the authorities are collected.)

"The status of slavery is not necessarily always attended with the same powers on the part of the master. The master is subject to the supreme power of the State, whose will controls his action towards his slave, and this control must be defined and regulated by the municipal law. In one State, as at one period of the Roman law, it may put the life of the slave into the hand of the master; others, as those of the United States, which tolerate slavery, may treat the slave as a person, when the master takes his life; while in others, the law may recognize a right of the slave to be protected from cruel treatment. In other words, the status of slavery embraces every condition, from that in which the slave is known to the law simply as a chattel, with no civil rights, to that in which he is recognized as a person for all purposes, save the compulsory power of directing and receiving the fruits of his labor. Which of these conditions shall attend the status of slavery, must depend on the municipal law which creates and upholds it.

"And not only must the status of slavery be created and measured by municipal law, but the rights, powers, and obliga

tions, which grow out of that status, must be defined, protected, and enforced, by such laws. The liability of the master for the torts and crimes of his slave, and of third persons for assaulting or injuring, or harboring or kidnapping him, the forms and modes of emancipation and sale, their subjection to the debts of the master, succession by death of the master, suits for freedom, the capacity of the slave to be party to a suit, or to be a witness, with such police regulations as have existed in all civilized States. where slavery has been tolerated, are among the subjects upon which municipal legislation becomes necessary when slavery is introduced.

"Is it conceivable that the Constitution has conferred the right on every citizen to become a resident on the Territory of the United States with his slaves, and there to hold them as such, but has neither made nor provided for any municipal regulations which are essential to the existence of slavery?

"Is it not more rational to conclude that they who framed and adopted the Constitution were aware that persons held to service under the laws of a State are property only to the extent and under the conditions fixed by those laws; that they must cease to be available as property, when their owners voluntarily place them permanently within another jurisdiction, where no municipal laws on the subject of slavery exist; and that, being aware of these principles, and having said nothing to interfere with or displace them, or to compel Congress to legislate in any particular manner on the subject, and having empowered Congress to make all needful rules and regulations respecting the territory of the United States, it was their intention to leave to the discretion of Congress what regulations, if any, should be made concerning slavery therein? Moreover, if the right exists, what are its limits, and what are its conditions? If citizens of the United States have the right to take their slaves to a Territory, and hold them there as slaves, without regard to the laws of the Territory, I suppose this right is not to be restricted to the citizens of slaveholding States. A citizen of a State which does not tolerate slavery can hardly be denied the power of doing the same thing. And what law of slavery does either take with
