A judicial system is a framework of courts and legal institutions that interprets and applies the law. It ensures that justice is served by resolving disputes, protecting rights, and punishing wrongdoers. The system typically includes various levels of courts, such as trial courts, appellate courts, and supreme courts, each with specific roles in the legal process. Judicial systems vary by country but generally follow similar principles, such as the right to a fair trial and the presumption of innocence. Key players in this system include judges, lawyers, and jurors, all working together to uphold the rule of law and maintain social order.
