The Federal Supreme Court is the highest court in the United States, responsible for interpreting the Constitution and federal laws. It has the authority to review decisions made by lower courts and can rule on cases that involve significant legal questions or disputes between states. Established in 1789, the court consists of nine justices, including a Chief Justice. Justices are nominated by the President and confirmed by the Senate. The court's decisions set important legal precedents that influence the interpretation of laws and the rights of individuals across the country.
