The respondents, former employees and officers of a union local, brought an application before the Ontario Labour Relations Board alleging unfair labour practices.
They requested the vice-chair recuse himself because he had previously acted for one of the respondents in an employment dispute.
The vice-chair declined and dismissed the application for serving no labour relations purpose.
The Divisional Court quashed the decisions, finding a conflict of interest.
The Court of Appeal allowed the appeal, holding that the Divisional Court erred by applying the test for a lawyer's conflict of interest rather than the test for reasonable apprehension of bias by an adjudicator.
The Court found the presumption of impartiality was not rebutted and reinstated the vice-chair's decisions.
