The appellant was convicted of sexually assaulting his cellmate at a detention centre by forcing him to engage in oral sex on three occasions.
He was sentenced to four years' imprisonment.
On appeal, the appellant challenged both his conviction and sentence.
The conviction appeal was dismissed as the trial judge's credibility assessments were properly reasoned and entitled to substantial deference.
The sentence appeal was also dismissed, with the court finding the four-year sentence was fit and properly reflected the principles of sentencing.
The victim surcharge imposed at trial was set aside.
