The United States Supreme Court is the highest court in the federal judiciary of the United States. Established in 1789, it has the authority to interpret the Constitution and review laws and decisions made by lower courts. The Court consists of nine justices, including a Chief Justice, who are appointed by the President and confirmed by the Senate. The Supreme Court plays a crucial role in upholding the rule of law and protecting individual rights. It hears cases that often involve significant legal questions, and its decisions set important precedents that guide future cases and legislation across the country.
