How many justices are on the U.S. Supreme Court?

The U.S. Supreme Court is comprised of nine justices, a number that has been established since 1869. This includes one Chief Justice and eight Associate Justices. The composition of the Court is crucial as it reflects the judicial philosophy and ideologies that can influence landmark decisions affecting various aspects of law and society.

The number of justices is set by Congress, and throughout history, it has varied. However, since the late 19th century, maintaining nine justices has become standard practice, thereby ensuring a full bench can deliberate and decide on cases without deadlocks, which could occur with an even number of justices. This structure aims to uphold the stability and functionality of the highest court in the nation.
