Congress is the only body that can make laws
States cannot make laws that go against the US Constitution
The Supreme Court has final say in all court matters
The President is the supreme executive of the government and no other branch of government is as powerful.

It means that the Constitution is the highest law in the United States and all other laws, whether federal or state, must comply with it. The Constitution establishes the framework for the government, outlines the rights and responsibilities of citizens, and sets limits on the powers of the government. Any law or action that is inconsistent with the Constitution can be declared unconstitutional by the courts. Essentially, the Constitution is the ultimate authority in determining the legitimacy of laws and actions within the country.
