“If the federal government should overpass the just bounds of its authority and make a tyrannical use of its powers, the people, whose creature it is, must appeal to the standard they have formed, and take such measures to redress the injury done to the Constitution as the exigency may suggest and prudence justify. The propriety of a law, in a constitutional light, must always be determined by the nature of the powers upon which it is founded. .. would not be the supreme law of the land, but a usurpation of power not granted by the Constitution.” Federalist #33
