Background

M.M. was convicted of sexual assault in the Ontario Court of Justice on October 18, 2024. He appealed the conviction to the Court of Appeal for Ontario.

The appeal alleged, as its primary ground, that the trial judge’s conduct created a reasonable apprehension of bias. The appeal court’s reasons do not set out the underlying facts of the alleged assault.

The Court’s Holding

The Court of Appeal allowed the appeal. It held that the trial judge’s prolonged and at times confrontational questioning of M.M. amounted to cross-examination, rather than permissible judicial questioning to clarify evidence or address matters counsel should have explored.

The court found that this conduct would lead a reasonable observer to doubt the judge’s neutrality. The concern was heightened because the judge questioned M.M. before his counsel re-examined him, directly challenged his credibility, and relied on evidence she elicited in rejecting his testimony. The court rejected the Crown’s submission that the absence of a contemporaneous objection supported an inference that no reasonable apprehension of bias existed.

Key Takeaways

  • A trial judge may clarify evidence, but may not assume the role of cross-examiner.
  • Judicial questioning that challenges an accused’s credibility can create a reasonable apprehension of bias.
  • Whether judicial conduct undermines trial fairness is assessed objectively by the appellate court; the lack of an objection at trial is not determinative.

Why It Matters

The decision underscores that judicial neutrality must be maintained both in fact and appearance. When a judge’s intervention crosses into adversarial questioning and is then used to assess credibility, the resulting unfairness can require a new trial.

Having allowed the appeal on this ground, the court did not address M.M.’s other ground of appeal. It quashed the conviction and ordered a new trial.
