An Appellate Court is a higher court that reviews decisions made by lower courts, such as trial courts. Its primary function is to determine whether legal errors occurred during the trial that could have affected the outcome. Appellate Courts do not conduct new trials or hear new evidence; instead, they focus on the application of the law and the procedures followed in the original case. These courts typically consist of a panel of judges who examine written briefs submitted by both parties and may hold oral arguments. The judges then issue a ruling, which can affirm, reverse, or modify the lower court's decision, ensuring that justice is served according to the law.
