Supremacy Clause
U.S. Const. art. VI, cl. 2
The Constitution, federal laws made pursuant to it, and treaties are the 'supreme Law of the Land.' When valid federal law conflicts with state law, federal law preempts (overrides) the state law. State judges are bound by it regardless of contrary state constitutions or statutes.
