A magistrate judge serves in the United States federal court system by assisting district court judges with their caseloads. The primary role of a person in this position is to handle ancillary duties often performed by district judges so that those judges can handle more trials. In some cases, he or she will decide a criminal or civil case if both parties consent to having the trial handled by a magistrate judge instead of a district judge.
According to the Federal Judicial Center, the U.S. federal court system hears more than one million cases per year. The position of federal magistrate was created in 1968 by the U.S. Congress’ Federal Magistrates Act to help federal courts handle more trials; the job title was changed to magistrate judge in 1990. These positions are given to federal district courts based on caseload criteria.
The U.S. Congress established powers and responsibilities that magistrate judges can perform, but because of the diversity of district courts, it is up to the court’s discretion which duties are given to magistrate-level judges. The district court chooses to use these judges in whatever capacity they need to in order to expedite cases. These judges are appointed by a majority vote of active district judges and are eligible for reappointment.
