A supernumerary judge or supernumerary magistrate is a judge who has retired from a full-time position on a court, but continues to work part-time.
Generally, when a judge becomes supernumerary a vacancy is created, and the appropriate person or body may subsequently make a new appointment to that Court.
The role of supernumerary judges varies by jurisdiction.
[2][3] Supernumerary judicial positions are also widely used in Canada.
The salary of each supernumerary judge of a superior court is the salary annexed to the office of a judge of that court other than a chief justice, senior associate chief justice, or associate chief justice.
