Which of the following is the highest court in the federal system?

The U.S. Supreme Court is the highest court in the federal system, serving as the ultimate court of appeal in the United States. Established by the Constitution, it has the final authority on matters of federal law and constitutional interpretation. Decisions made by the U.S. Supreme Court are binding across the entire country, and it has the power to overturn decisions made by lower federal courts and state courts.

This hierarchy of courts is crucial for understanding the judicial system: U.S. District Courts serve as trial courts, U.S. Courts of Appeals review decisions made by District Courts, and Congress, while influential in the legislative process, does not serve a judicial function. The Supreme Court's role is to interpret the law and ensure that it is applied consistently and fairly, which underscores its position as the highest court in the federal system.
