How many members are there on the Supreme Court?

The Supreme Court of the United States is composed of nine members, which includes one Chief Justice and eight Associate Justices. This structure has been in place since the Judiciary Act of 1869, which established that the Court should have nine justices. The number is significant because it allows for a full court to deliberate on cases without the possibility of a tie, ensuring that decisions can be made efficiently and effectively.

Having nine justices also reflects the importance of having a diverse panel to interpret the Constitution and federal laws from multiple perspectives. This composition enables the Court to address a wide range of legal and constitutional issues that arise in American society. The other choices reflect incorrect numbers, as there have never been seven, eleven, or twelve justices on the Supreme Court, highlighting the established tradition of nine justices in the Court's history.
