The process for selecting a military judge is closely analogous to that found in the civilian system. People who wish to make application to be assessed for appointment as military judges provide their names to the military judges selection committee. The administration of the process of that committee is actually done for us by the Commissioner for Federal Judicial Affairs--the body that does a similar process for the administration of assessment of civilian nominees.
The military judges selection committee currently comprises five persons: a retired Superior Court judge; a nominee of the Canadian Bar Association; a civilian lawyer; the officer occupying the position of Chief of Military Personnel; and, to ensure that the perspective of non-commissioned members is represented, a Canadian Forces chief warrant officer.
The military judges selection committee would provide a recommendation on each applicant to the Minister of National Defence. He would then select the name of the person he considers to be advisable and take it forward to cabinet. That would ultimately lead to an appointment of the military judge by the Governor in Council.
