The appellant appealed a jury conviction for sexual assault arising from sexual activity at a house party involving an intoxicated complainant and later DNA confirmation.
The court held that the jury charge was fatally deficient because it failed to properly put the defence position, conflated actual and mistaken belief in consent, misstated the burden of proof by implying the accused had to prove consent beyond a reasonable doubt, and referred to wilful blindness without defining it.
Although the charge also included unnecessary references to vitiating factors unsupported by the evidence, that error alone was not reversible.
Considering the cumulative effect of the charge errors, the court declined to apply the curative proviso, quashed the conviction, and ordered a new trial.
