 argument to the contrary is to be deduced from the restraint laid upon the States in relation to duties on imports and exports. This restriction implies an admission, that if it were not inserted, the States would possess the power it excludes; and it implies a further admission, that as to all other taxes the authority of the States remains undiminished. In any other view it would be both unnecessary and dangerous; it would be unnecessary, because if the grant to the Union of the power of laying such duties implied the exclusion of the States, or even their subordination in this particular, there could be no need of such a restriction; it would be dangerous, because the introduction of it leads directly to the conclusion which has been mentioned, and which, if the reasoning of the objectors be just, could not have been intended; I mean that the States, in all cases to which the restriction did not apply, would have a concurrent power of taxation with the Union. The restriction in question amounts to what lawyers call a ; that is, a negation of one thing, and an affirmation of another: a negation of the authority of the States to impose taxes on imports and exports, and an affirmance of their authority to impose them on all other articles. It would be mere sophistry to argue that it was meant to exclude them absolutely from the imposition of taxes of the former kind, and to leave them at liberty to lay others subject to the control of the National Legislature. The restraining or prohibitory clause only says, that they shall not, without the consent of Congress, lay such duties; and if we are to understand this in the sense last mentioned, the Constitution would then be made to introduce a formal provision for the sake of a very absurd conclusion; which is, that the States, with the consent of the National Legislature, might tax imports and exports; and that they might tax every other article, unless controlled by the
