Sir, I deny this power of State legislatures altogether. It cannot stand the test of examination. Gentlemen may say, that, in an extreme case, a State government might protect the people from intolerable oppression. Sir, in such a case, the people might protect themselves, without the aid of the State governments. Such a case warrants revolution. It must make, when it comes, a law for itself. A nullifying act of a State legislature cannot alter the case, nor make resistance any more lawful. In maintaining these sentiments, Sir, I am but asserting the rights of the people. I state what they have declared, and insist on their right to declare it. They have chosen to repose this power in the general government, and I think it my duty to support it, like other constitutional powers. For myself, Sir, I do not admit the competency of South Carolina, or any other State, to prescribe my constitutional duty; or to settle, between me and the people, the validity of laws of Congress for which I have voted. I decline her umpirage. I have not sworn to support the Constitution according to her construction of its clauses. I have not stipulated, by my oath of office or otherwise, to come under any responsibility, except to the people, and those whom they have appointed to pass upon the question, whether laws, supported by my votes, conform to the Constitution of the country. And, Sir, if we look to the general nature of the case, could anything have been more preposterous, than to make a government for the whole Union, and yet leave its powers subject, not to one interpretation, but to thirteen or twenty-four interpretations? Instead of one tribunal, established by all, responsible to all, with power to decide for all, shall constitutional questions be left to four-and-twenty popular bodies, each at liberty to decide for itself, and none bound to respect the decisions of others,--and each at liberty, too, to give a new construction on every new election of its own members? Would anything, with such a principle in it, or rather with such a destitution of all principle, be fit to be called a government? No, Sir. It should not be denominated a Constitution. It should be called, rather, a collection of topics for everlasting controversy; heads of debate for a disputatious people. It would not be a government. It would not be adequate to any practical good, or fit for any country to live under.
