Appeals courts, also known as appellate courts, are higher-level courts that review decisions made by lower courts, such as trial courts. Their primary role is to determine whether legal errors occurred during the trial that could have affected the outcome. Appeals courts do not conduct new trials; instead, they examine the records from the original case and listen to arguments from both sides. These courts typically consist of a panel of judges who evaluate the case based on written briefs and oral arguments. If the appeals court finds that an error was made, it can reverse or modify the lower court's decision, or sometimes send the case back for a new trial.
