The original judiciary branch included a Supreme Court made up of six justices.

Explanation:

The Constitution does not specify the number of members that the Supreme Court must have. It is the Congress that has the power to set the number of judges. Originally, the total number of judges was set at six by the Judiciary Act of 1789. When the country grew geographically, the number of judges increased. The Court was extended to seven members in 1807, to nine in 1837 and to ten in 1863.

By the Circuit Judges Act of 1869, the number of judges was again set at nine (a Chief Justice and eight Associate Justices), a composition that has been maintained ever since.
