How does the Supremacy Clause affect state laws?

The Supremacy Clause, found in Article VI of the United States Constitution, establishes that federal law takes precedence over state law. This means that when there is a conflict between federal law and state law, federal law must be followed. This principle ensures a consistent legal framework across all states, promoting unity and coherence in the application of laws throughout the country.

It is critical for maintaining the structure of federalism in the United States, as it empowers the federal government to implement and enforce its laws without state interference. The clause also serves as a foundation for the judicial system to resolve disputes where such conflicts arise. The understanding of this clause is key to grasping the balance of power between federal and state governments within the framework of American governance.
