The appellant, R.H., appealed his conviction for sexual assault.
The complainant testified that she consented to the sexual touching, which occurred due to the appellant's drug-induced paranoid hallucinations about her infidelity.
The trial judge, despite the complainant's testimony of consent and the Crown's argument focusing on the complainant's inconsistent police statement, convicted the appellant on the basis that her consent was vitiated by the history of violence in their relationship.
This theory of vitiated consent was not advanced by either counsel during the trial, nor was it raised by the judge with the parties before the decision.
The Court of Appeal found that convicting the appellant on an unargued and uncanvassed theory constituted a fundamental unfairness and denied the appellant his constitutional right to make full answer and defence.
The appeal was allowed, the sexual assault conviction was set aside, and a new trial was ordered on that count.
