A District Court Judge is a judicial officer who presides over cases in a district court, which is a trial court in the state or federal court system. Their primary role is to interpret the law, ensure fair trials, and make decisions on various legal matters, including civil and criminal cases. District court judges often handle preliminary hearings, motions, and jury selections. These judges are appointed or elected, depending on the jurisdiction, and they serve a specific term or until retirement. They play a crucial role in the legal system by ensuring that justice is administered fairly and efficiently within their respective districts.
