A United States Supreme Court Justice is a member of the highest court in the federal judiciary of the United States. This court interprets the Constitution and federal laws, making decisions that can have a significant impact on American society. Justices are nominated by the President and confirmed by the Senate, serving lifetime appointments unless they resign, retire, or are removed. The Supreme Court consists of nine justices, including one Chief Justice and eight Associate Justices. They hear cases that often involve important legal questions, such as civil rights, federal authority, and individual liberties. Their rulings set precedents that guide lower courts and influence future legislation.
