The Constitution Comes Before Statutes, Edicts, Ordinances, Rules or Regulations Article VI, U.S. Constitution 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, anything in the Constitution or laws of any State to the contrary notwithstanding. The Senators and Representatives before mentioned, and the members of the several state legislatures, and all executive and judicial officers, both of the United States and of the several states, shall be bound by oath or affirmation, to support this Constitution; but no religious test shall ever be required as a qualification to any office or public trust under the United States. From Law.Cornell.Edu: "This means that state governments and officials cannot take actions or pass laws that interfere with the Constitution, laws passed by Congress, or treaties. The Constitution was interpreted, in 1819, as giving the Supreme Court the power to invalidate any state actions that interfere with the Constitution and the laws and treaties passed pursuant to it. That power is not itself explicitly set out in the Constitution but was declared to exist by the Supreme Court in the decision of McCulloch v. Maryland."
