Administrative law 2024 ONCA 910

West Whitby Landowners Group Inc. v. Elexicon Energy Inc.

Leave to appeal was granted because the issues raise questions of public importance and legal significance that affect the development of Ontario jurisprudence—specifically whether certain OEB decisions or staff opinions are insulated from judicial review—and therefore warrant determination by the Court of Appeal rather than being treated as final under a rigid application of Re Sault Dock.

Criminal law 2023 NSCA 85

R. v. Cummings

The motions judge correctly dismissed the Notice of Judicial Review as filed beyond the time limits in CPR 64.03 and 7.05; the appellant's jurisdictional complaints were without merit; and the Court of Appeal cannot validly declare the appellant a vexatious litigant in relation to criminal proceedings because Parliament has exclusive authority over criminal law and procedure and the appellant retains a statutory appeal right under s.784 of the Criminal Code, therefore the Crown's motion is dismissed and the appeal is dismissed.

  • Judicial review
  • Certiorari
  • Prohibition
  • Vexatious litigant
  • Timeliness/limitation rules
  • Separation of powers
