The applicants sought judicial review of an Ontario Labour Relations Board decision declaring them to be a single employer bound by a collective agreement and liable for damages.
The applicants argued procedural unfairness and challenged the Board's earlier certification and grievance decisions.
The Divisional Court dismissed the application, finding it to be an improper collateral attack on previous Board decisions.
The Court held that the Board's procedures were fair and its calculation of damages, based on established principles for breaches of union security provisions in the construction industry, was reasonable.
