The appellant school board appealed a decision of the Quebec Court of Appeal affirming a Superior Court judgment that granted the respondent union's application for judicial review of an arbitral award.
The Supreme Court of Canada allowed the appeal, finding that the arbitrator's award, which interpreted the collective agreement regarding the assignment of teaching staff, contained no patently unreasonable error.
The Court held that the arbitrator's approach was rational and based on the collective agreement and education legislation, meaning it could not be challenged before the courts.
