The applicant, a military musician in the Canadian Forces, grieved the denial of a promotion to Sergeant after a new ranking policy replaced the previous policy.
The Military Grievances External Review Committee recommended allowing the grievance, but the Final Authority dismissed it.
The Federal Court granted the application for judicial review, holding that the Final Authority's decision was unreasonable because it failed to adequately justify its departure from the Committee's recommendations regarding the fairness of the transition period and unreasonably assessed the applicant's eligibility for an Acting/Lacking promotion under the applicable policies.
