How many justices comprised the original Supreme Court?

The original Supreme Court, established by the Judiciary Act of 1789, consisted of six justices. This foundational group was made up of one Chief Justice and five Associate Justices. The Court was designed to serve as the highest judicial authority in the United States, interpreting the Constitution and federal laws. Over time, the number of justices has changed, but the initial composition was indeed set at six. The other options do not reflect the correct historical context of the Court’s formation.
