Circuit Courts are a type of state court in the United States that handle a variety of cases, including civil and criminal matters. They serve as trial courts, meaning they are where cases are first heard and decided. Each state has its own system of Circuit Courts, which are usually organized by geographic regions, allowing them to serve local communities effectively. These courts play a crucial role in the judicial system, as they often hear appeals from lower courts and make important legal decisions. Judges in Circuit Courts are typically elected or appointed, and their rulings can significantly impact the law and the lives of individuals involved in legal disputes.
