How many justices are on the Supreme Court?

The Supreme Court of the United States is comprised of nine justices. This number has been established since 1869 and includes one Chief Justice and eight Associate Justices. The role of these justices is to interpret the Constitution and federal law, and they are appointed for life, allowing for continuity and stability in the interpretation of laws over time. The decision to have nine justices balances the need for a diverse range of opinions while ensuring a majority can reach decisions on important legal matters. This structure plays a crucial role in the judicial system, making the selection of justices a highly significant process given their lasting impact on American law and society.
