So, Sir, I understood the gentleman, and am happy to find that I did not misunderstand him. What he contends for is that it is constitutional to interrupt the administration of the Constitution itself, in the hands of those who are chosen and sworn to administer it, by the direct interference, in form of law, of the States, in virtue of their sovereign capacity. The inherent right in the people to reform their government I do not deny; and they have another right, and that is to resist unconstitutional laws, without overturning the government. It is no doctrine of mine that unconstitutional laws bind the people. The great question is, Whose prerogative is it to decide on the constitutionality or unconstitutionality of the laws? On that the main debate hinges. The proposition that, in case of a supposed violation of the Constitution by Congress, the States have a constitutional right to interfere and annul the law of Congress, is the proposition of the gentleman. I do not admit it. If the gentleman had intended no more than to assert the right of revolution for justifiable cause, he would have said only what all agree to. But I cannot conceive that there can be a middle course, between submission to the laws, when regularly pronounced constitutional, on the one hand, and open resistance, which is revolution or rebellion, on the other. I say the right of a State to annul a law of Congress cannot be maintained, but on the ground of the inalienable right of man to resist oppression; that is to say, upon the ground of revolution. I admit that there is an ultimate violent remedy, above the Constitution and in defiance of the Constitution, which may be resorted to when a revolution is to be justified. But I do not admit that, under the Constitution and in conformity with it, there is any mode in which a State government, as a member of the Union, can interfere and stop the progress of the general government, by force of her own laws, under any circumstances whatever.
