Final answer:
Congress, as per Article III of the U.S. Constitution, has the power to create inferior federal courts, taking part in shaping the federal judiciary system and ensuring a complete national judicial structure.
Step-by-step explanation:
According to Article III of the Constitution, Congress has the power to create inferior federal courts. This provision allows Congress to establish a system of lower courts under the Supreme Court. The idea behind this structure is to ensure that there is a comprehensive judicial system capable of handling various cases and appeals across the United States. The judicial power granted by the Constitution includes the creation of these lower courts as part of the federal judiciary system.
Under Article III, not only is the Supreme Court established as the highest court, but Congress also has the responsibility for developing the judiciary beyond this. The generality of Article III in terms of the judiciary was later expanded upon with the passage of the Federal Judiciary Act of 1789, which organized the Supreme Court and established the lower federal courts.
The creation of these inferior courts is a reflection of the significant role that the legislative branch plays in shaping the federal judiciary.
