What is the highest law of the land?

The Constitution is recognized as the highest law of the land due to the Supremacy Clause, which is found in Article VI, Clause 2 of the United States Constitution. This clause establishes that the Constitution, along with federal laws made in accordance with it and treaties made under its authority, takes precedence over any conflicting state laws.

The foundational role of the Constitution lies in its function as the primary source of authority for the governance of the country, outlining the structure of government, the separation of powers, and individual rights. When any law, whether it be a state law, federal statute, or international treaty, contradicts the Constitution, the Constitution prevails. This principle ensures a uniform standard of law and protects citizens’ rights at a national level, preventing states from enacting contradictory laws that could undermine those rights or the federal governance structure.

While state laws, international treaties, and federal statutes play critical roles in the legal landscape, they must always align with the Constitution. Any laws or treaties that violate the Constitution can be deemed unconstitutional and thus null and void. This hierarchy of laws underscores the Constitution's position as the ultimate authority in the United States legal system.
