What does Article VI, Section 2 of the US Constitution establish?

Article VI, Section 2 of the U.S. Constitution establishes that the Constitution, along with federal laws and treaties made under its authority, constitutes the supreme law of the land. This principle implies that when state laws conflict with federal laws, federal law prevails. This provision underscores the concept of federalism in the United States, which delineates the relationship between the national government and the states. By articulating that the Constitution is the supreme law, it ensures that all judges are bound by it, regardless of state laws that may contradict it.

This section serves to unify the legal framework within which the country operates, affirming the superiority of federal law in legal disputes and reinforcing the authority of the Constitution as the foundational document for the nation's governance.
