R v Nahn, William

The respondent, William Nahn, was convicted following a trial in the Supreme Court of South Australia of sexual intercourse without consent, as well as an indecent assault. The court was required to determine the sentence to be imposed on the respondent. The court considered whether the standard non-parole period applied to offences of attempt, and if so, whether it should be reduced due to the particular circumstances of the case. The court also considered the impact on the victim, the respondent’s criminal history, and his mental health condition.

The court found that the standard non-parole period applied to the offence of attempted sexual intercourse without consent. However, it found that special circumstances existed which warranted a reduction in the non-parole period. The court considered the victim impact statement, which detailed the significant impact the offences had on the victim, as well as the psychological report of the offender, which conflicted with his evidence of denial. The court also considered the respondent’s prior criminal history, as well as the subsequent offence, which was only considered in determining the likelihood of reoffending. The court found that the respondent’s mental health condition would be treated on sentence.

The court found that the offences were of high moral blameworthiness, and that a substantial sentence of imprisonment was necessary to adequately reflect the community’s condemnation of the respondent’s conduct. The court found that special circumstances existed which warranted a reduction in the non-parole period, including the respondent’s early guilty plea, his remorse, and the fact that he had no prior convictions for sexual offences. The court also found that the respondent’s mental health condition would be treated on sentence, and that this was a mitigating factor. The court ultimately determined that a full-time custodial sentence was appropriate, with a non-parole period of nine years.
