The High Court has dismissed an appeal concerning evidence of other misconduct in a historic child sexual abuse prosecution. The accused, aged 58, was convicted of three sexual offences against his younger sister (by two years and ten months): carnal knowledge when the accused was 17 and the complainant was 14; rape when the accused was 28 and the complainant was 25 and a second rape when the accused was 29 and the complainant was 26. At the trial, the prosecution also presented evidence of other sexual incidents, including in a bathtub when the accused was 6 and the complainant was 3; in an implement shed when the accused was 8 and the complainant was 5; in a bedroom when the accused was 9 and the complainant was 6; in a shearing shed when the accused was around 10 and the complainant was around 7; and persistent sexual offending when the accused was aged 18 to 20 and the complainant was aged 15 to 17. The accused was originally convicted of offences in relation to the shearing shed and the persistent sexual offending, but these were quashed by the Full Court of the South Australian Supreme Court on the grounds that the accused was too young to be criminally responsible for the shearing shed incident and the evidence of the persistent sexual offending was too imprecise to support a conviction for that offence. The Full Court nevertheless upheld the accused’s convictions for carnal knowledge and two rapes.
The High Court (Kiefel CJ, Bell, Gageler, Nettle and Gordon JJ) unanimously dismissed the accused’s argument that he should be retried on the remaining convictions because the prosecution offered evidence of the other uncharged (or charged, but incapable of sustaining a guilty verdict) incidents. The joint judgment noted (at [17]) that the Court’s recent ruling in Bauer v The Queen means that evidence of uncharged acts involving the complainant and the accused ‘will commonly have very high probative value as circumstantial evidence of the accused’s propensity to act on his or her sexual attraction to the complainant’; however, despite originally asking to use the evidence in this way, the prosecution in this case did not use the evidence for that purpose at the trial. The probative value of such ‘non-propensity’ evidence – to place otherwise inexplicable evidence in context; or to explain the complainant’s or accused’s conduct – ‘lies in its capacity to assist in evaluating the evidence of the offence’, while its prejudicial effect ‘is concerned is the risk that the jury will make some improper use of the evidence’ ([19]). There is seldom such a risk when the evidence is sourced from the complainant, especially where the jury is carefully directed on use ([20]) and there is no logical reason why the length of time since the alleged events will increase this risk ([21]).
The joint judgment held that the evidence offered to support the count of persistent sexual abuse, although inadequate for that purpose, was important to the evaluation of the two counts of rape. Continue reading →
