The court system is a structured network of legal institutions that interpret and apply the law. It consists of various levels, including trial courts, appellate courts, and supreme courts, each serving different functions. Trial courts handle initial cases, while appellate courts review decisions made by trial courts to ensure the law was correctly applied. Judges and juries play key roles in the court system. Judges oversee court proceedings, ensuring fairness and adherence to legal procedures, while juries, composed of citizens, may be called to determine the facts of a case. This system aims to uphold justice and resolve disputes.
