Upon general principles, then, the government of the United States possesses this authority; and this would hardly be denied were it not that there are other governments. But since there are State governments, and since these, like other governments, ordinarily construe their own powers, if the government of the United States construes its own powers also, which construction is to prevail in the case of opposite constructions? And again, as in the case now actually before us, the State governments may undertake, not only to construe their own powers, but to decide directly on the extent of the powers of Congress. Congress has passed a law as being within its just powers; South Carolina denies that this law is within its just powers, and insists that she has the right so to decide this point, and that her decision is final. How are these questions to be settled?

In my opinion, Sir, even if the Constitution of the United States had made no express provision for such cases, it would yet be difficult to maintain, that, in a Constitution existing over four-and-twenty States, with equal authority over all, one could claim a right of construing it for the whole. This would seem a manifest impropriety; indeed, an absurdity. If the Constitution is a government existing over all the States, though with limited powers, it necessarily follows, that, to the extent of those powers, it must be supreme. If it be not superior to the authority of a particular State, it is not a national government. But as it is a government, as it has a legislative power of its own, and a judicial power coextensive with the legislative, the inference is irresistible that this government, thus created by the whole and for the whole, must have an authority superior to that of the particular government of any one part. Congress is the legislature of all the people of the United States; the judiciary of the general government is the judiciary of all the people of the United States. To hold, therefore, that this legislature and this judiciary are subordinate in authority to the legislature and judiciary of a single State, is doing violence to all common sense, and overturning all established principles. Congress must judge of the extent of its own powers so often as it is called on to exercise them, or it cannot act at all; and it must also act independent of State control, or it cannot act at all.

The right of State interposition strikes at the very foundation of the legislative power of Congress. It possesses no effective legislative power, if such right of State interposition exists; because it can pass no law not subject to abrogation. It cannot make laws for the Union, if any part of the Union may pronounce its enactments void and of no effect. Its forms of legislation would be an idle ceremony, if, after all, any one of four-and-twenty States might bid defiance to its authority. Without express provision in the Constitution, therefore, Sir, this whole question is necessarily decided by those provisions which create a legislative power and a judicial power. If these exist in a government intended for the whole, the inevitable consequence is, that the laws of this legislative power and the decisions of this judicial power must be binding on and over the whole. No man can form the conception of a government existing over four-and-twenty States, with a regular legislative and judicial power, and of the existence at the same time of an authority, residing elsewhere, to resist, at pleasure or discretion, the enactments and the decisions of such a government. I maintain, therefore, Sir, that, from the nature of the case, and as an inference wholly unavoidable, the acts of Congress and the decisions of the national courts must be of higher authority than State laws and State decisions. If this be not so, there is, there can be, no general government.

But, Mr. President, the Constitution has not left this cardinal point without full and explicit provisions. First, as to the authority of Congress. Having enumerated the specific powers conferred on Congress, the Constitution adds, as a distinct and substantive clause, the following, viz.: "To make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this Constitution in the government of the United States, or in any department or officer thereof." If this means anything, it means that Congress may judge of the true extent and just interpretation of the specific powers granted to it, and may judge also of what is necessary and proper for executing those powers. If Congress is to judge of what is necessary for the execution of its powers, it must, of necessity, judge of the extent and interpretation of those powers.

And in regard, Sir, to the judiciary, the Constitution is still more express and emphatic. It declares that the judicial power shall extend to all cases in law or equity arising under the Constitution, laws of the United States, and treaties; that there shall be one Supreme Court, and that this Supreme Court shall have appellate jurisdiction of all these cases, subject to such exceptions as Congress may make. It is impossible to escape from the generality of these words. If a case arises under the Constitution, that is, if a case arises depending on the construction of the Constitution, the judicial power of the United States extends to it. It reaches the case, the question; it attaches the power of the national judicature to the case itself, in whatever court it may arise or exist; and in this case the Supreme Court has appellate jurisdiction over all courts whatever. No language could provide with more effect and precision than is here done, for subjecting constitutional questions to the ultimate decision of the Supreme Court. And, Sir, this is exactly what the Convention found it necessary to provide for, and intended to provide for. It is, too, exactly what the people were universally told was done when they adopted the Constitution. One of the first resolutions adopted by the Convention was in these words, viz.: "That the jurisdiction of the national judiciary shall extend to cases which respect the collection of the national revenue, and questions which involve the national peace and harmony." Now, Sir, this either had no sensible meaning at all, or else it meant that the jurisdiction of the national judiciary should extend to these questions, with a paramount authority. It is not to be supposed that the Convention intended that the power of the national judiciary should extend to these questions, and that the power of the judicatures of the States should also extend to them, with equal power of final decision. This would be to defeat the whole object of the provision. There were thirteen judicatures already in existence. The evil complained of, or the danger to be guarded against, was contradiction and repugnance in the decisions of these judicatures. If the framers of the Constitution meant to create a fourteenth, and yet not to give it power to revise and control the decisions of the existing thirteen, then they only intended to augment the existing evil and the apprehended danger by increasing still further the chances of discordant judgments. Why, Sir, has it become a settled axiom in politics that every government must have a judicial power coextensive with its legislative power? Certainly, there is only this reason, namely, that the laws may receive a uniform interpretation and a uniform execution. This object cannot be otherwise attained. A statute is what it is judicially interpreted to be; and if it be construed one way in New Hampshire, and another way in Georgia, there is no uniform law. One supreme court, with appellate and final jurisdiction, is the natural and only adequate means, in any government, to secure this uniformity. The Convention saw all this clearly; and the resolution which I have quoted, never afterwards rescinded, passed through various modifications, till it finally received the form which the article now bears in the Constitution.

It is undeniably true, then, that the framers of the Constitution intended to create a national judicial power, which should be paramount on national subjects. And after the Constitution was framed, and while the whole country was engaged in discussing its merits, one of its most distinguished advocates, Mr. Madison, told the people that it was true, that, in controversies relating to the boundary between the two jurisdictions, the tribunal which is ultimately to decide is to be established under the general government. Mr. Martin, who had been a member of the Convention, asserted the same thing to be the legislature of Maryland, and urged it as a reason for rejecting the Constitution. Mr. Pinckney, himself also a leading member of the Convention, declared it to the people of South Carolina. Everywhere it was admitted, by friends and foes, that this power was in the Constitution. By some it was thought dangerous, by most it was thought necessary; but by all it was agreed to be a power actually contained in the instrument. The Convention saw the absolute necessity of some control in the national government over State laws. Different modes of establishing this control were suggested and considered. At one time, it was proposed that the laws of the States should, from time to time, be laid before Congress, and that Congress should possess a negative over them. But this was thought inexpedient and inadmissible; and in its place, and expressly as a substitute for it, the existing provision was introduced; that is to say, a provision by which the federal courts should have authority to overrule such State laws as might be in manifest contravention of the Constitution. The writers of the Federalist, in explaining the Constitution, while it was yet pending before the people, and still unadopted, give this account of the matter in terms, and assign this reason for the article as it now stands. By this provision Congress escaped the necessity of any revision of State laws, left the whole sphere of State legislation quite untouched, and yet obtained a security against any infringement of the constitutional power of the general government. Indeed, Sir, allow me to ask again, if the national judiciary was not to exercise a power of revision on constitutional questions over the judicatures of the States, why was any national judicature erected at all? Can any man give a sensible reason for having a judicial power in this government, unless it be for the sake of maintaining a uniformity of decision on questions arising under the Constitution and laws of Congress, and insuring its execution? And does not this very idea of uniformity necessarily imply that the construction given by the national courts is to be the prevailing construction? How else, Sir, is it possible that uniformity can be preserved?

Gentlemen appear to me, Sir, to look at but one side of the question. They regard only the supposed danger of trusting a government with the interpretation of its own powers. But will they view the question in its other aspect? Will they show us how it is possible for a government to get along with four-and-twenty interpreters of its laws and powers? Gentlemen argue, too, as if, in these cases, the State would be always right, and the general government always wrong. But suppose the reverse,--suppose the State wrong (and, since they differ, some of them must be wrong),--are the most important and essential operations of the government to be embarrassed and arrested, because one State holds the contrary opinion? Mr. President, every argument which refers the constitutionality of acts of Congress to State decision appeals from the majority to the minority; it appeals from the common interest to a particular interest; from the counsels of all to the counsel of one; and endeavors to supersede the judgment of the whole by the judgment of a part.

I think it is clear, Sir, that the Constitution, by express provision, by definite and unequivocal words, as well as by necessary implication, has constituted the Supreme Court of the United States the appellate tribunal in all cases of a constitutional nature which assume the shape of a suit, in law or equity. And I think I cannot do better than to leave this part of the subject by reading the remarks made upon it in the convention of Connecticut, by Mr. Ellsworth; a gentleman, Sir, who has left behind him, on the records of the government of his country, proofs of the clearest intelligence and the deepest sagacity, as well as of the utmost purity and integrity of character. "This Constitution," says he, "defines the extent of the powers of the general government. If the general legislature should, at any time, overleap their limits, the judicial department is a constitutional check. If the United States go beyond their powers, if they make a law which the Constitution does not authorize, it is void; and the judiciary power, the national judges, who, to secure their impartiality, are to be made independent, will declare it to be void. On the other hand, if the States go beyond their limits, if they make a law which is a usurpation upon the general government, the law is void; and upright, independent judges will declare it to be so." Nor did this remain merely matter of private opinion. In the very first session of the first Congress, with all these well-known objects, both of the Convention and the people, full and fresh in his mind, Mr. Ellsworth, as is generally understood, reported the bill for the organization of the judicial department, and in that bill made provision for the exercise of this appellate power of the Supreme Court, in all the proper cases, in whatsoever court arising; and this appellate power has now been exercised for more than forty years, without interruption, and without doubt.

As to the cases, Sir, which do not come before the courts, those political questions which terminate with the enactments of Congress, it is of necessity that these should be ultimately decided by Congress itself. Like other legislatures, it must be trusted with this power. The members of Congress are chosen by the people, and they are answerable to the people; like other public agents, they are bound by oath to support the Constitution. These are the securities that they will not violate their duty, nor transcend their powers. They are the same securities that prevail in other popular governments; nor is it easy to see how grants of power can be more safely guarded, without rendering them nugatory. If the case cannot come before the courts, and if Congress be not trusted with its decision, who shall decide it? The gentleman says, each State is to decide it for herself. If so, then, as I have already urged, what is law in one State is not law in another. Or, if the resistance of one State compels an entire repeal of the law, then a minority, and that a small one, governs the whole country.

Sir, those who espouse the doctrines of nullification reject, as it seems to me, the first great principle of all republican liberty; that is, that the majority must govern. In matters of common concern, the judgment of a majority must stand as the judgment of the whole. This is a law imposed on us by the absolute necessity of the case; and if we do not act upon it, there is no possibility of maintaining any government but despotism. We hear loud and repeated denunciations against what is called majority government. It is declared, with much warmth, that a majority government cannot be maintained in the United States. What, then, do gentlemen wish? Do they wish to establish a minority government? Do they wish to subject the will of the many to the will of the few? The honorable gentleman from South Carolina has spoken of absolute majorities and majorities concurrent; language wholly unknown to our Constitution, and to which it is not easy to affix definite ideas. As far as I understand it, it would teach us that the absolute majority may be found in Congress, but the majority concurrent must be looked for in the States; that is to say, Sir, stripping the matter of this novelty of phrase, that the dissent of one or more States, as States, renders void the decision of a majority of Congress, so far as that State is concerned. And so this doctrine, running but a short career, like other dogmas of the day, terminates in nullification.
