The primary function of higher-level appellate courts is to hear appeals from lower trial courts. In the judicial system, appellate courts review decisions made by trial courts to ensure that the law was applied correctly and that the legal proceedings were conducted fairly. They do not retry cases or hear new evidence; instead, they focus on whether legal errors occurred during the trial that could have impacted the outcome. This function is crucial for maintaining the integrity of the judicial system, ensuring that individuals have a mechanism to challenge and appeal decisions they believe to be unjust or improperly adjudicated.

Other functions mentioned, such as supervising parolees and conducting preliminary hearings, are typically associated with lower courts or specific legal processes rather than the primary role of appellate courts, which are focused on the review of previously decided cases. Administering justice in the community can encompass various judicial roles, but it is not a specific duty of appellate courts. Thus, the function of reviewing trial court decisions most accurately defines the role of higher-level appellate courts.
