PDF Version: Judicial Review on the Vires of Subordinate Legislation
Case Commented On: West Fraser Mills Ltd. v British Columbia (Workers’ Compensation Appeal Tribunal), 2018 SCC 22 (CanLII)
Judicial review on the vires of subordinate legislation is a subject I previously examined in a March 2016 post concerning subordinate legislation enacted by the Alberta College of Pharmacists and its dispute with Sobeys over the use of consumer inducements in retail pharmacies. I noted back in 2016 there was some uncertainty over the standard of review a court should apply when reviewing the vires of legislation enacted by a statutory tribunal or other delegate. Indeed, the whole concept of judicial review on the vires of subordinate legislation is a bit murky in Canadian administrative law. The Supreme Court’s decision in West Fraser Mills Ltd. v British Columbia (Workers’ Compensation Appeal Tribunal), 2018 SCC 22 (CanLII) addresses the topic, but unfortunately the Court is split and fails to situate its reasoning with the Court’s Katz Group Canada Inc. v. Ontario (Health and Long Term Care, 2013 SCC 64 (Katz) decision which also addresses the principles governing a vires determination of subordinate legislation. The majority in West Fraser Mills rules that the principles set out in Dunsmuir govern judicial review on the enactment of subordinate legislation by a statutory tribunal, and therefore where the tribunal’s governing legislation provides for the power to enact subordinate legislation the presumption of reasonableness applies to a review on the vires of that legislation. The dissenting justices hold the standard ought to be correctness.
