Strict duty would require of me nothing more than the exercise of those powers with which I am now or may hereafter be invested for preserving the peace of the Union and for the execution of the laws; but the imposing aspect which opposition has assumed in this case, by clothing itself with State authority, and the deep interest which the people of the United States must all feel in preventing a resort to stronger measures while there is a hope that anything will be yielded to reasoning and remonstrance, perhaps demand, and will certainly justify, a full exposition to South Carolina and the nation of the views I entertain of this important question, as well as a distinct enunciation of the course which my sense of duty will require me to pursue. The ordinance is founded, not on the indefeasible right of resisting acts which are plainly unconstitutional and too oppressive to be endured, but on the strange position that any one State may not only declare an act of Congress void, but prohibit its execution; that they may do this consistently with the Constitution; that the true construction of that instrument permits a State to retain its place in the Union and yet be bound by no other of its laws than those it may choose to consider as constitutional. It is true, they add, that to justify this abrogation of a law it must be palpably contrary to the Constitution; but it is evident that to give the right of resisting laws of that description, coupled with the uncontrolled right to decide what laws deserve that character, is to give the power of resisting all laws; for as by the theory there is no appeal, the reasons alleged by the State, good or bad, must prevail. If it should be said that public opinion is a sufficient check against the abuse of this power, it may be asked why it is not deemed a sufficient guard against the passage of an unconstitutional act by Congress? There is, however, a restraint in this last case which makes the assumed power of a State more indefensible, and which does not exist in the other. There are two appeals from an unconstitutional act passed by Congress--one to the judiciary, the other to the people and the States. There is no appeal from the State decision in theory, and the practical illustration shows that the courts are closed against an application to review it, both judges and jurors being sworn to decide in its favor. But reasoning on this subject is superfluous when our social compact, in express terms, declares that the laws of the United States, its Constitution, and treaties made under it are the supreme law of the land, and, for greater caution, adds "that the judges in every State shall be bound thereby, anything in the constitution or laws of any State to the contrary notwithstanding." And it may be asserted without fear of refutation that no federative government could exist without a similar provision. Look for a moment to the consequence.
