What is the supreme law of the land?

The U.S. Constitution is regarded as the supreme law of the land primarily because it establishes the foundational framework for the federal government and delineates the rights and responsibilities of its citizens. It is the highest form of law in the United States, meaning that any law passed by federal or state legislatures that conflicts with the Constitution is deemed invalid. This principle is established by the Supremacy Clause found in Article VI of the Constitution, which clearly states that the Constitution, along with federal laws made pursuant to it, and treaties made under its authority, shall be the supreme law of the land.

In contrast, federal law, while it holds significant authority, is subordinate to the Constitution. State laws also hold power within their respective jurisdictions, but they cannot contravene federal laws or the Constitution itself. International law, while relevant in specific contexts, does not take precedence over the U.S. Constitution within domestic law. Thus, the U.S. Constitution's primacy underlines its role as the ultimate legal authority in the country.
