Sir, the human mind is so constituted that the merits of both sides of a controversy appear very clear, and very palpable, to those who respectively espouse them; and both sides usually grow clearer as the controversy advances. South Carolina sees unconstitutionality in the tariff; she sees oppression there also, and she sees danger. Pennsylvania, with a vision not less sharp, looks at the same tariff, and sees no such thing in it; she sees it all constitutional, all useful, all safe. The faith of South Carolina is strengthened by opposition, and she now not only sees, but resolves, that the tariff is palpably unconstitutional, oppressive, and dangerous; but Pennsylvania, not to be behind her neighbors, and equally willing to strengthen her own faith by a confident asseveration, resolves, also, and gives to every warm affirmative of South Carolina, a plain, downright, Pennsylvania negative. South Carolina, to show the strength and unity of her opinion, brings her assembly to a unanimity, within seven voices; Pennsylvania, not to be outdone in this respect any more than in others, reduces her dissentient fraction to a single vote. Now, Sir, again I ask the gentleman, What is to be done? Are these States both right? Is he bound to consider them both right? If not, which is in the wrong? or rather, which has the best right to decide? And if he, and if I, are not to know what the Constitution means, and what it is, till those two State legislatures, and the twenty-two others, shall agree in its construction, what have we sworn to, when we have sworn to maintain it? I was forcibly struck, Sir, with one reflection, as the gentleman went on in his speech. He quoted Mr. Madison’s resolutions, to prove that a State may interfere, in a case of deliberate, palpable, and dangerous exercise of a power not granted. The honorable member supposes the tariff law to be such an exercise of power; and that consequently a case has arisen in which the State may, if it see fit, interfere by its own law. Now, it so happens, nevertheless, that Mr. Madison deems this same tariff law quite constitutional. Instead of a clear and palpable violation, it is, in his judgment, no violation at all. So that, while they use his authority for a hypothetical case, they reject it in the very case before them. All this, Sir, shows the inherent futility, I had almost used a stronger word, of conceding this power of interference to the State, and then attempting to secure it from abuse by imposing qualifications of which the States themselves are to judge. One of two things is true: either the laws of the Union are beyond the discretion and beyond the control of the States; or else we have no constitution of general government, and are thrust back again to the days of the Confederation.

I must now beg to ask, Sir, Whence is this supposed right of the States derived? Where do they find the power to interfere with the laws of the Union? Sir, the opinion which the honorable gentleman maintains is a notion founded in a total misapprehension, in my judgment, of the origin of this government, and of the foundation on which it stands. I hold it to be a popular government, erected by the people; those who administer it responsible to the people; and itself capable of being amended and modified, just as the people may choose it should be. It is as popular, just as truly emanating from the people, as the State governments. It is created for one purpose; the State governments for another. It has its own powers; they have theirs. There is no more authority with them to arrest the operation of a law of Congress, than with Congress to arrest the operation of their laws. We are here to administer a Constitution emanating immediately from the people, and trusted by them to our administration. It is not the creature of the State governments. It is of no moment to the argument, that certain acts of the State legislatures are necessary to fill our seats in this body. That is not one of their original State powers, a part of the sovereignty of the State. It is a duty which the people, by the Constitution itself, have imposed on the State legislatures; and which they might have left to be performed elsewhere, if they had seen fit. So they have left the choice of President with electors; but all this does not affect the proposition that this whole government, President, Senate, and House of Representatives, is a popular government. It leaves it still all its popular character. The governor of a State (in some of the States) is chosen, not directly by the people, but by those who are chosen by the people, for the purpose of performing, among other duties, that of electing a governor. Is the government of the State, on that account, not a popular government? This government, Sir, is the independent offspring of the popular will. It is not the creature of State legislatures; nay, more, if the whole truth must be told, the people brought it into existence, established it, and have hitherto supported it, for the very purpose, amongst others, of imposing certain salutary restraints on State sovereignties. The States cannot now make war; they cannot contract alliances; they cannot make, each for itself, separate regulations of commerce; they cannot lay imposts; they cannot coin money. If this Constitution, Sir, be the creature of State legislatures, it must be admitted that it has obtained a strange control over the volitions of its creators.

The people erected the government.

A constitution with enumerated powers.

The main design of the Constitution to free the government from State agency.

The failure of the Confederation the cause of the Constitution.

The people, then, Sir, erected this government. They gave it a Constitution, and in that Constitution they have enumerated the powers which they bestow on it. They have made it a limited government. They have defined its authority. They have restrained it to the exercise of such powers as are granted; and all others, they declare, are reserved to the States or the people. But, Sir, they have not stopped here. If they had, they would have accomplished but half their work. No definition can be so clear as to avoid possibility of doubt; no limitation so precise as to exclude all uncertainty. Who, then, shall construe this grant of the people? Who shall interpret their will, where it may be supposed they have left it doubtful? With whom do they repose this ultimate right of deciding on the powers of the government? Sir, they have settled all this in the fullest manner. They have left it with the government itself, in its appropriate branches. Sir, the very chief end, the main design, for which the whole Constitution was framed and adopted, was to establish a government that should not be obliged to act through State agency, or depend on State opinion and State discretion. The people had had quite enough of that kind of government under the Confederation. Under that system, the legal action, the application of law to individuals, belonged exclusively to the States. Congress could only recommend; their acts were not of binding force till the States had adopted and sanctioned them. Are we in that condition still? Are we yet at the mercy of State discretion and State construction? Sir, if we are, then vain will be our attempt to maintain the Constitution under which we sit.

But, Sir, the people have wisely provided, in the Constitution itself, a proper, suitable mode and tribunal for settling questions of constitutional law. There are in the Constitution grants of powers to Congress, and restrictions on these powers. There are, also, prohibitions on the States. Some authority must, therefore, necessarily exist, having the ultimate jurisdiction to fix and ascertain the interpretation of these grants, restrictions, and prohibitions. The Constitution has itself pointed out, ordained, and established that authority. How has it accomplished this great and essential end? By declaring, Sir, that “the Constitution, and the laws of the United States, made in pursuance thereof, shall be the supreme law of the land, any thing in the constitution or laws of any State to the contrary notwithstanding.”

The supremacy of the Constitution.

The final decision of the Supreme Court.
