A police officer resigned to avoid disciplinary action but later attempted to withdraw his resignation.
The Chief of Police refused the withdrawal, prompting the union to file a grievance.
The arbitrator ruled she lacked jurisdiction because police discipline is governed by the Police Act, 1990, not the collective agreement.
The Court of Queen's Bench upheld this decision, but the Court of Appeal reversed it.
The Supreme Court of Canada allowed the appeal, applying the Weber test to conclude that the essential character of the dispute was disciplinary and fell within the exclusive statutory scheme of the Police Act.
