What type of courts can Congress create?

Congress has the authority to establish "inferior courts" as specified in Article III, Section 1 of the U.S. Constitution. This section provides that the judicial power of the United States shall be vested in one Supreme Court and in such inferior courts as Congress may from time to time ordain and establish. The term "inferior courts" refers to all lower federal courts that fall beneath the Supreme Court in the federal judiciary. This includes district courts and courts of appeals, which Congress has indeed created under its constitutional power.

The option related to Supreme Courts specifically refers only to the one Supreme Court established by the Constitution, which is not something Congress can create but rather recognizes the existing court. Therefore, the focus on inferior courts aligns directly with Congress's authority to create a structure within the federal judiciary, allowing for the diverse needs of legal cases across the nation.
