Courts of Appeal are higher-level courts that review decisions made by lower courts, such as trial courts. Their primary role is to ensure that the law was applied correctly and that legal procedures were followed. These courts do not conduct new trials; instead, they examine the records from the original case and listen to arguments from both sides. In many legal systems, including the United States, Courts of Appeal are divided into different circuits or districts. They typically consist of a panel of judges who deliberate and issue written opinions, which can set important legal precedents for future cases.
