Board declines to hear jurisdictional dispute already decided by private arbitration plan, applying issue estoppel.
The applicant union filed a complaint regarding a work assignment dispute.
The responding union raised a preliminary objection, arguing that the matter had already been decided by an arbitrator under the Plan for Settlement of Jurisdictional Disputes, to which all parties were bound.
The Ontario Labour Relations Board agreed, finding that the applicant was bound by the Plan's decision through its collective agreement.
Applying the doctrine of issue estoppel, the Board exercised its discretion under section 99 of the Labour Relations Act, 1995 to decline to inquire further into the complaint, emphasizing the policy of deferring to private dispute resolution mechanisms agreed to by the parties.
