What is the supreme law of the land?

The Constitution of the United States is established as the supreme law of the land by the Supremacy Clause found in Article VI, Clause 2. This clause asserts that the Constitution, along with federal laws and treaties made pursuant to it, take precedence over state laws and constitutions. This foundational principle ensures that federal law is the final authority in the legal hierarchy of the United States.

The Declaration of Independence, while a pivotal document in American history, is not a binding legal text and serves primarily as a statement of principles and grievances against the British Crown. The Bill of Rights, which comprises the first ten amendments to the Constitution, outlines specific protections for individual liberties but does not serve as the foundational governing document. Federal Law is contingent upon and must align with the Constitution; it does not independently hold the status of supreme law.
