The appropriate total sentence for two offences of sexual assault and one of blackmail was an immediate custodial term of three years. When imposing a suspended sentence of 18 months’ imprisonment, the sentencing judge had given too much weight to mitigating factors, including the fact that the offender had Asperger’s Syndrome, and insufficient weight to the seriousness of the blackmail offence. He had also erred in finding that the victim’s apparent consent to sexual activity on one occasion had lessened the seriousness of the subsequent sexual assaults.
