What figure is the federal court system best described as?

The federal court system in the United States is best described as a hierarchical structure consisting of three main levels: the District Courts, the Courts of Appeals, and the Supreme Court. District Courts serve as the trial courts where cases are initially heard, while the Courts of Appeals review decisions made by the District Courts. Finally, the Supreme Court is the highest court, which has the authority to interpret the Constitution and resolve significant legal questions. This structure ensures a system of checks and balances, promoting fairness and uniformity in the application of federal law.
