The supremacy clause says that laws established by stand above all other laws

The Supremacy Clause is contained in Article VI.

It states 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, anything in the Constitution or laws of any State to the contrary notwithstanding.

So, the Federal Constitution stands above all the rest.
