Section 58 — Canada Labour Code: Decisions not to be reviewed by court

Every order or decision of an arbitrator or arbitration board is final and shall not be questioned or reviewed in any court. No order shall be made, process entered or proceeding taken in any court, whether by way of injunction, certiorari , prohibition, quo warranto or otherwise, to question, review, prohibit or restrain an arbitrator or arbitration board in any of their proceedings under this Part. For the purposes of the Federal Courts Act , an arbitrator appointed pursuant to a collective agreement or an arbitration board is not a federal board, commission or other tribunal within the meaning of that Act.
