How many justices serve on the Supreme Court?

The Supreme Court of the United States is composed of nine justices. This has been the standard since 1869, when Congress established the number to ensure a definitive decision-making body. The justices are appointed by the President and confirmed by the Senate, serving lifetime appointments unless they resign, retire, or are removed by impeachment. The structure of having an odd number of justices helps to prevent tie votes in cases that are heard by the Court. This established framework contributes to the Court's authority and stability in interpreting the Constitution and federal law. Other choices, which suggest different numbers of justices, do not align with the historical and legal framework surrounding the Supreme Court's composition.
