A Supreme Court Justice is a member of the highest court in the United States, known as the Supreme Court. This court interprets the Constitution and federal laws, making decisions that can impact the entire country. Justices are appointed by the President and confirmed by the Senate, serving lifetime terms unless they choose to retire or are removed. There are nine justices on the Supreme Court, including one Chief Justice and eight Associate Justices. They hear cases that often involve significant legal questions, such as civil rights, federal authority, and individual freedoms, shaping the law and society in profound ways.
