“Arbitrators, like judges, are required to follow the law of the land. Section 31 of the Arbitration Act, 1991 provides:
Application of law and equity
31 An arbitral tribunal shall decide a dispute in accordance with law, including equity, and may order specific performance, injunctions and other equitable remedies.
In Omers Realty Corp. v. Sears Canada Inc. (2005), 2005 CanLII 3983 (ON SC), 74 O.R. (3d) 423 (S.C.), at para. 22, aff’d (2006), 2006 CanLII 16477 (ON CA), 80 O.R. (3d) 561 (C.A.), Pepall J. (as she then was) explained at para. 22:
Section 31 of the Arbitration Act, 1991 provides that an arbitral tribunal is to decide a dispute in accordance with the law. The arbitration represents a process to address a dispute; it does not confer jurisdiction to ignore or rewrite the law and established legal principles. Put differently, the arbitration provision does not confer on the arbitrators the ability to do what they please unencumbered by applicable legal principles.
There are many sources of law. The courts do not have a monopoly on establishing the content of the law. But the Arbitration Act, 1991 creates a hierarchy that feeds into the judicial hierarchy and attracts the doctrine of stare decisis. Section 37 of the statute provides:
Binding nature of award
37 An award binds the parties, unless it is set aside or varied under section 45 or 46 (appeal, setting aside award).
Subsection 45(5) of the Arbitration Act, 1991 provides,
Idem
(5) The court may confirm, vary or set aside the award or may remit the award to the arbitral tribunal with the court’s opinion on the question of law, in the case of an appeal on a question of law, and give directions about the conduct of the arbitration.
The effect of these provisions is that once an arbitrator’s decision is set aside, it no longer binds. The court is expressly provided with the authority to opine on questions of law and to give directions to the arbitrator in consequence. It is implicit in the section and consonant with stare decisis and common sense, that the court’s determination of the law and the court’s directions do indeed bind the arbitrator as they bind the parties.”
