How many justices are on the Supreme Court?

The Supreme Court of the United States is composed of nine justices. This composition has been in place since 1869. The nine justices include one Chief Justice and eight Associate Justices. This number is established through legislation passed by Congress, signaling the importance of a stable and consistent structure at the highest court level. Having nine justices allows for a majority to be reached during hearings and decisions, enabling the court to effectively address legal issues and controversies that arise before it.

In contrast, the other options suggest differing numbers of justices that do not align with current federal law or practice. Seven, eleven, or thirteen justices do not reflect the historical or current composition of the Supreme Court, which underscores the significance of the judicial system being organized and well-defined. Understanding this structure is essential for grasping how the judicial branch operates and how it plays a critical role in interpreting the law within the United States.
