How many justices serve on the Supreme Court?

The Supreme Court of the United States is composed of nine justices. This structure was established by the Judiciary Act of 1869, which set the number of justices at nine, and it has remained unchanged since then. The justices include one Chief Justice and eight Associate Justices, who are nominated by the President and confirmed by the Senate. Their role involves interpreting the Constitution, reviewing laws, and deciding cases that have significant legal implications. Having nine justices allows for a majority vote, which is essential for making decisions that guide U.S. law and policy.
