Supremacy Clause

Definition

The Supremacy Clause is a provision in Article VI of the U.S. Constitution stating that federal law takes precedence over state laws when there is a conflict. This clause ensures that the Constitution, along with federal laws and treaties made under its authority, serves as the supreme law of the land. It plays a crucial role in establishing a strong federal government by clarifying that state laws cannot undermine or contradict federal laws, particularly when it comes to treaties and executive agreements.

Review Questions

• How does the Supremacy Clause affect the relationship between state and federal governments?
  • The Supremacy Clause fundamentally shapes the relationship between state and federal governments by establishing that when there is a conflict between federal law and state law, federal law prevails.

Similarly, while executive agreements do not require Senate approval, they also must align with the Supremacy Clause, meaning states cannot enact laws that contradict them. This ensures that international commitments made by the U.S. government are upheld consistently across all states.

  • Court decisions have played a crucial role in interpreting the Supremacy Clause and shaping U.S. governance by confirming its authority in various contexts. Landmark cases like McCulloch v. Maryland established that states could not interfere with or tax legitimate activities of the federal government, thereby reinforcing federal supremacy. Such rulings have contributed to a clearer understanding of how state and federal powers interact, highlighting that while states retain their own powers, these powers cannot contradict or undermine federal authority as defined by the Constitution.
