Summary

Case summaries are prepared by the Office of the Registrar of the Supreme Court of Canada (Law Branch). Please note that summaries are not provided to the Judges of the Court. They are placed on the Court file and website for information purposes only.

The respondents sought an order to have the applicant’s action dismissed as frivolous, vexatious, and an abuse of process under Ontario’s Rules of Civil Procedure. A judge at the Ontario Superior Court of Justice granted the respondents’ request and dismissed the applicant’s action; the applicant was also prohibited from commencing any other claims, applications or other judicial proceedings against the respondents. A panel at the Court of Appeal unanimously dismissed the applicant’s appeal from the first judge’s order; the same panel then dismissed the applicant’s motion to set aside or reconsider its earlier decision.
