When a Trial Judge Offers an Opinion on a Contested Fact: Jury Trial
In charging juries, trial judges are obliged to review the substantial
parts of the evidence and relate that evidence to the issues the jurors must
decide.
Beyond summarizing the evidence, a trial judge is permitted to opine on
the evidence adduced at trial subject to certain limits.[1]
The overarching principle is fairness. Within this principle of fairness
is the recognition that the jury must remain the arbiter of the facts and that
any comments made by the trial judge cannot amount to a rebuttal of the defence
address to the jury or unfairly denigrate or undermine the position of the
defence.[2]
In R. v. Walker, 2019 ONCA 806, the trial judge offended this
rule by offering an opinion on a critical piece of evidence that was stronger than
the one the Crown had been prepared to advance: the Crown had conceded that a
gun was not clearly identifiable in security video footage, while the trial
judge opined to the jury that a gun was identifiable in the video. The Crown withdrew its concession and, in
closing, took a position with respect to
the gun that aligned with the judge’s. The Court of Appeal for Ontario held
that the trial judge’s comment rendered the trial unfair, as it had profoundly
impacted the course of argument on a critical piece of evidence.
In this case it was clear that the Crown had felt emboldened or obligated
to take a more aggressive position with respect to the gun evidence in light of
the judicial comment. However, the Court of Appeal may still have found the
trial unfair if the reason for the Crown’s shift in position had not been as
clear, for as the well-known legal axiom states: “ justice should not only be
done, but should manifestly and undoubtedly be seen to be done.”[3]
