How many justices serve on the Supreme Court?

The Supreme Court of the United States has nine justices. This includes one Chief Justice and eight Associate Justices. The number of justices has been set at nine since 1869, though it has changed in the past. The decision to establish nine justices allows for a balance in decision-making and provides a clear structure for the court's operations.

The Supreme Court plays a vital role in interpreting the Constitution and federal laws, and having an odd number of justices helps to avoid ties in rulings, which is essential for the court's function. The composition of the court can shift due to appointments made by the President and confirmations by the Senate, but the established number remains an important aspect of the judicial system.
