Selection of Judges

The Mesa City Council established a Judicial Advisory Board in 1997. This Board is responsible for:

  • recommending to the City Council the best qualified persons to become judges and
  • evaluating the performance of appointed judges and advising the City Council about retaining them.

The City Council reviews the recommendations from the Judicial Advisory Board and appoints the judges. The initial appointment is for a two-year term; if reappointed, the second term is a two-year term; subsequent reappointments are for four-year terms. Commissioners are appointed by the Presiding City Magistrate and preside over Civil Traffic Offenses.
