Which court hears exclusively appeal cases?

The U.S. Court of Appeals is specifically designed to handle appeals from lower courts and certain federal administrative agencies. Its primary function is to review decisions made by district courts, focusing on issues of law rather than fact. This means that when a case is appealed, it goes to the Court of Appeals where judges examine the trial's legal proceedings to determine if there were errors that materially affected the outcome. This appellate review is essential for ensuring that the law is applied consistently and fairly across different cases.

In contrast, the U.S. District Courts serve as the trial courts for federal cases, hearing matters at the initial level rather than appeals. State Superior Courts also operate primarily as trial courts within their respective states and manage various legal disputes without a specific appellate function. The U.S. Supreme Court primarily acts as the highest appellate court in the country, but it holds discretionary power over which cases to hear, focusing on significant legal issues or cases that could have broad implications. The distinct role of the U.S. Court of Appeals in handling exclusively appellate cases is what makes it the correct choice in this context.
