The accused, J.M., appealed his conviction for sexual assault.
The appeal focused on the trial judge's improper use of judicial notice, including drawing on personal experience as counsel and relying on external social science research (a magazine article and parallels to battered woman syndrome from *R. v. Lavallee*), to assess the complainant's credibility.
The Court of Appeal found that the trial judge exceeded the proper boundaries of judicial notice and violated procedural fairness by relying on information not put into evidence or subject to submissions.
The errors materially infected the credibility findings, which were central to the trial.
The curative proviso was not applicable due to the procedural unfairness.
The appeal was allowed, the conviction set aside, and a new trial ordered.
