In support of this opinion, they rely, in the first place, on the second section of the sixth article, which provides that — "This constitution, and the laws of the United States, which shall be made in pursuance thereof, and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land: and the judges in every State shall be bound thereby, any thing in the constitution or laws of any State to the contrary notwithstanding."
It is sufficient, in reply, to state, that the clause is declaratory; that it vests no new power whatever in the government, or in any of its departments. Without it, the constitution and the laws made in pursuance of it, and the treaties made under its authority, would have been the supreme law of the land, as fully and perfectly as they now are; and the judges in every State would have been bound thereby, any thing in the constitution or laws of a State, to the contrary notwithstanding. Their supremacy results from the nature of the relation between the federal government, and those of the several States, and their respective constitutions and laws. Where two or more States form a common constitution and government, the authority of these, within the limits of the delegated powers, must, of necessity, be supreme, in reference to their respective separate constitutions and governments. Without this, there would be neither a common constitution and government, nor even a confederacy. The whole would be, in fact, a mere nullity. But this supremacy is not an absolute supremacy. It is limited in extent
