The accused appealed from a Court of Appeal order setting aside his jury acquittal for first degree murder and directing a new trial.
The Supreme Court held that the trial judge seriously misdirected the jury by inviting application of the reasonable doubt standard to individual pieces of evidence rather than to the ultimate issues on the whole of the evidence, while recognizing a limited exception in credibility instructions.
The Court further held that psychiatric evidence elicited from a defence expert, tending only to place the accused within an abnormal group capable of the offence, was not admissible on identity because it lacked sufficiently distinctive traits and its prejudicial propensity effect predominated.
Although the Court found the Court of Appeal erred on the psychiatric evidence issue, it concluded the Crown met the stringent burden applicable on an appeal from acquittal by showing the verdict would not necessarily have been the same absent the misdirection.
The appeal was therefore dismissed and the order for a new trial stood.
