The branch is in charge of deciding the meaning of laws, how to use them in real situations, and whether a law breaks the rules of the Constitution. The Constitution is the highest law of our Nation. The U.S. Supreme Court, the highest court in the United States, is part of the judicial branch. The Supreme Court is made up of 9 judges called justices who are nominated by the President and confirmed by the Senate. The justices hear cases that have made their way up through the court system!
