Answer:
The Supremacy Clause of the U.S. Constitution states that the Constitutions itself, the treaties adopted under its authority and the federal laws are the supreme law within the United States territory.
Explanation:
By the Supremacy Clause, all the laws under the ones cited before must not be against these. Like the state constitutions. If there is an incongruency between laws the one with higher rank prevails.
The Constitution is the higher supreme law so all the laws including the federals and the treatises must be done according to what it says. If not it would be declared unconstitutional by the Supreme Court.
An example of this clause is the opinion in Marbury V. Madison in which the Supreme Court stated that Congress is not able to pass laws that went against what the Constitution said.
