What is considered the supreme law of the land?

The Constitution is considered the supreme law of the land due to its foundational role in establishing the framework of the federal government and delineating the rights of the states and the people. It serves as the highest legal authority in the United States, meaning that all laws, policies, and actions taken by government entities must align with its provisions. The Constitution's supremacy is established in Article VI, which explicitly states that it shall be the supreme law, meaning no state laws or individual actions can contravene it. This principle ensures a cohesive legal standard across the entire country, promoting unity and stability within the governance system.

While the Declaration of Independence is a significant historical document that declared the colonies' separation from Britain, it does not function as law. The Bill of Rights, which comprises the first ten amendments to the Constitution, specifically enshrines individual freedoms but does not supersede the Constitution itself. Additionally, federal regulations are rules enacted by federal agencies to enforce statutory laws and are subject to the Constitution, further affirming that the Constitution holds the highest authority in the legal hierarchy.
