What is the highest authority in the federal hierarchy of law?

The Constitution is the highest authority in the federal hierarchy of law due to its foundational role in the United States legal system. It serves as the supreme law of the land, establishing the framework of government and outlining the rights and responsibilities of both the state and federal authorities.

Any legislation, administrative regulations, or judicial opinions must align with the Constitution; if there is a conflict, the Constitution prevails. This supremacy ensures that all laws enacted by Congress or regulations created by administrative agencies are subordinate to constitutional principles. Furthermore, the Constitution provides the basis for the judicial branch to interpret laws and settle disputes, reinforcing its position as the highest authority. This hierarchy underscores the importance of the Constitution in maintaining the rule of law and protecting individual rights within the United States.
