Judicial review of labour board decision dismissed; board's interpretation of collective agreement was reasonable.
The applicant union sought judicial review of an Ontario Labour Relations Board decision regarding a work jurisdiction dispute over exterior concrete formwork at a hospital construction project.
The Board had upheld the employer's assignment of the work to a composite crew of Carpenters and Labourers, finding that the Labourers' collective agreement did not explicitly claim the disputed work.
The Divisional Court dismissed the application, holding that the Board's interpretation of the collective agreement was reasonable and that the Board was not bound to follow its prior decisions where the circumstances or arguments differed.
