Final answer:
The basis of all law in the U.S. is the U.S. Constitution, known as the supreme law of the land. All other laws, including those passed by Congress, state laws, and local ordinances, are subordinate to the Constitution.
Step-by-step explanation:
The basis of all law in the United States is the U.S. Constitution, which is the fundamental law of the country. It creates the branches of government, identifies their powers and limitations, and outlines the basic rights and obligations of citizens. It is considered the supreme law of the land, as laid out in Article VI of the Constitution. This hierarchy places the Constitution at the peak, followed by federal treaties and laws, then state constitutions, state laws, and local ordinances. The rule of law emphasizes that all decisions by those who govern must adhere to the principles outlined in the Constitution, ensuring that no one, regardless of status, is above the law. The role of Congress is to make laws, but this power is balanced by the President, who can veto legislation, and the Supreme Court, which can review laws' constitutionality through judicial review.
