Background
GR was tried in the District Court of New South Wales on allegations of sexual offending against his two stepdaughters. An earlier trial had included additional charges concerning his biological daughter, but those charges were discontinued after she testified that she could not identify who had assaulted her. That jury was discharged, and a new trial began the following day on an amended indictment that excluded those charges.
During the second trial, three witnesses made references capable of suggesting that GR had also sexually offended against his biological daughter or other sisters of the complainants. Two answers were struck from the record and followed by brief directions to disregard them, while the third attracted no contemporaneous direction. The trial judge refused the defence application to discharge the jury. The jury later convicted GR of five offences against his stepdaughters, and he appealed on the sole ground that the refusal to discharge the jury caused a miscarriage of justice.
The Court’s Holding
The Court of Criminal Appeal unanimously allowed the appeal. Rigg J, with Free JA and Sirtes J agreeing, held that the three passages, considered in the context of the trial, created an irregularity that could realistically have affected the jury’s reasoning toward the guilty verdicts. The evidence was highly prejudicial because it could suggest additional sexual misconduct against GR’s biological daughter and thereby improperly bolster the complainants’ credibility or indicate a broader propensity to offend. The brief directions did not eliminate that risk.
The Court declined to apply the proviso permitting convictions to stand where no substantial miscarriage of justice occurred. The case depended substantially on contested credibility: the complainants gave evidence that the offences occurred, while GR testified and denied them. Although text messages were capable of being treated as admissions, GR offered alternative explanations connected to his drinking and family relationships. Given the appellate court’s limitations in assessing witnesses from the record, it could not conclude beyond reasonable doubt that GR was guilty of every charge. It granted leave, quashed the convictions, and ordered a retrial.
Key Takeaways
- A conviction appeal may succeed where improperly received evidence had a realistic capacity to influence the jury’s reasoning, even if the evidence was introduced inadvertently.
- Directions to disregard prejudicial evidence will not invariably cure the harm, particularly where repeated references imply similar uncharged sexual misconduct.
- The proviso is difficult to apply when guilt turns on competing witness credibility and the prejudicial material may have affected the jury’s assessment of that credibility.
Why It Matters
The decision underscores the need for trial courts to assess the cumulative effect of prejudicial references, rather than treating each remark in isolation. In sexual-offence trials, suggestions of misconduct against an additional child can carry exceptional weight and may compromise the fairness of the proceeding despite limiting directions.
It also confirms the restricted role of an appellate court under the proviso. Where resolving guilt requires choosing between competing accounts given by witnesses whom the appellate judges did not observe, a strong prosecution case is not enough: the court must itself be satisfied beyond reasonable doubt before allowing affected convictions to stand.
