What does the supremacy clause establish about federal and state laws?

The supremacy clause, found in Article VI, Clause 2 of the United States Constitution, establishes that federal law takes precedence over state laws whenever there is a conflict between the two. This means that if a state law contradicts a federal law, the federal law is considered the supreme law of the land and must be followed. The supremacy clause aims to ensure a consistent legal framework across the nation and resolve disputes that may arise from differing state laws.

Understanding this principle is crucial because it reinforces the idea that while states have the power to create and enforce their own laws, they cannot enact laws that undermine or contradict federal authority on matters that fall under federal jurisdiction. This concept is foundational in maintaining a balance of power between state and federal governments.
