How many justices are on the Supreme Court?

The number of justices on the Supreme Court of the United States is nine. This has been the case since 1869, when Congress established the size of the Court. The Supreme Court is the highest federal court in the United States and plays a vital role in interpreting the Constitution and federal law. Having nine justices allows for a balance of opinions and helps to prevent ties in decision-making, as the Court's rulings require a majority.

This number can sometimes be misunderstood, as the composition of the Court has changed over time, but it has remained nine since the late 19th century. The other answer choices incorrectly suggest different numbers of justices, which do not reflect the current structure of the Supreme Court.
