M'Culloch v. Maryland · ¶61

The sovereignty of a State extends to every thing which exists by its own authority, or is introduced by its permission; but does it extend to those means which are employed by Congress to carry into execution powers conferred on that body by the people of the United States? We think it demonstrable that it does not. Those powers are not-given by the people of a single State. They are given by the people of the United States, to a government whose laws, made in pursuance of the constitution, are declared to be supreme. Consequently, the people of a single State cannot confer a sovereignty which will extend over them.
