The appellant appealed his convictions for sexual assault with a weapon, uttering threats, and sexual interference.
The trial judge found that the appellant had sexually assaulted a 15-year-old complainant at a property he owned, holding a knife to her throat and forcing her to perform fellatio.
The appellant's defence relied on a medical condition affecting his genitals and a theory of innocent secondary transfer of semen.
The Court of Appeal upheld the convictions, finding no errors in the trial judge's assessment of credibility, treatment of DNA evidence, or application of the collateral fact rule.
