John Marshall Quote

This great principle is that the Constitution and the laws made in pursuance thereof are supreme; that they control the Constitution and laws of the respective States, and cannot be controlled by them. From this, which may be almost termed an axiom, other propositions are deduced as corollaries, on the truth or error of which, and on their application to this case, the cause has been supposed to depend. These are, 1st. That a power to create implies a power to preserve; 2d. That a power to destroy, if wielded by a different hand, is hostile to, and incompatible with these powers to create and to preserve; 3d. That, where this repugnancy exists, that authority which is supreme must control, not yield to that over which it is supreme.
