The appellant, A.B., appealed his conviction for sexual assault, arguing errors in the trial judge's jury charge regarding prior inconsistent statements, demeanour evidence, and wilful blindness/recklessness.
The Court of Appeal dismissed the first two grounds but found that the trial judge erred in instructing the jury on the mens rea requirement for sexual assault, specifically regarding recklessness and wilful blindness.
The trial judge's instruction incorrectly suggested an objective standard ("should have inquired") rather than the required subjective standard of knowledge.
The court found this error was not harmless, especially given the jury's acquittal on other counts, suggesting a potential reasoning error based on what a reasonable person ought to have known.
The appeal was allowed, and a new trial was ordered.
