What is the supreme law of the land?

The Constitution is recognized as the supreme law of the land because it serves as the foundational legal document that establishes the framework of the United States government and defines the rights of its citizens. This principle is rooted in the Supremacy Clause found in Article VI of the Constitution, which explicitly states that the Constitution, along with federal laws made pursuant to it, and treaties made under its authority, take precedence over state laws and constitutions. This hierarchy ensures a uniform legal standard across the nation, meaning that when state laws conflict with the Constitution, the Constitution prevails. The strength and authority of the Constitution underlie the structure of American law, making it the ultimate source for judicial interpretation and law enforcement.
