• The Supreme Court

The U.S. Supreme Court has complete authority over all federal courts. Its rulings have a significant effect. A Supreme Court ruling can affect the outcome of many cases in the lower courts. The Supreme Court’s interpretations of federal laws and of the Constitution are final. The Supreme Court is limited in its power over the states. It cannot make decisions about state law or state constitutions. The Court can decide that a state law or action conflicts with federal law or with the U.S. Constitution. If this happens, the state law becomes invalid. The Supreme Court case ruling Marbury v. Madison established this power, known as “judicial review.” The Supreme Court also rules on cases about significant social and public policy issues that affect all Americans. The Supreme Court ruled on the court case Brown v. the Board of Education of Topeka, which ended racial segregation in schools.

•   Reviews laws
•   Explains laws
•   Resolves disputes (disagreements)
•   Decides if a law goes against the Constitution

The judicial branch is one of the three branches of government. The Constitution established the judicial branch of government with the creation of the Supreme Court. Congress created the other federal courts. All these courts together make up the judicial branch. The courts review and explain the laws, and they resolve disagreements about the meaning of the law. The U.S. Supreme Court makes sure that laws are consistent with the Constitution. If a law is not consistent with the Constitution, the Court can declare it unconstitutional. In this case, the Court rejects the law. The Supreme Court makes the final decision about all cases that have to do with federal laws and treaties. It also rules on other cases, such as disagreements between states.
