SUPREMACY CLAUSE

The Supremacy Clause, found in Article VI, Clause 2 of the U.S. Constitution, establishes that the Constitution, federal laws made pursuant to it, and treaties are the “supreme Law of the Land”. It mandates that federal law takes precedence over conflictin state or local laws, making it a foundation of American Federalism and judicial review.

It ensures that judges in every state are bound by the Constitution and federal laws, even if state constitutions or laws contradict them.

Essentially, when state and federal law conflict, the federal government wins under the Supremacy Clause.
