What is the supreme law of the land?

The Constitution is considered the supreme law of the land because it establishes the framework of the American government and defines the rights of its citizens. It serves as the ultimate legal authority, meaning that all laws and government actions must be consistent with the Constitution. This principle is rooted in the Supremacy Clause, found in Article VI, Clause 2, which asserts that the Constitution, federal laws made pursuant to it, and treaties made under its authority are the highest form of law.

As such, when conflicts arise between federal law and state law, the Constitution prevails, ensuring uniformity and protecting individual rights across the nation. While federal laws and state laws govern various aspects of society, they cannot contravene the Constitution. International laws, while significant in foreign affairs and treaties, do not take precedence over the U.S. Constitution. The foundation and authority of the Constitution make it the ultimate legal framework in the United States.
