R v S

In the case of R v S, the appellant was convicted of multiple sexual offences against two of his step-daughters. The appellant made admissions to each girl about his sexual activity with the other, and the trial judge declined to order separate trials for the offences. The appellant challenged the decision, arguing that the trial judge erred in ruling that evidence of the commission of offences against one girl was inadmissible in the case involving the other girl, as it did not meet the criteria for similar fact evidence. This ruling impacted the admissibility of crucial evidence in the case.

The court was required to determine whether the trial judge had correctly applied the criteria for admitting similar fact evidence in the context of sexual offences. The court examined the established tests from cases such as Pfennig, O’Keefe, Wackerow, and Hooper to ascertain whether the evidence of the commission of offences against one girl was admissible in the case involving the other girl. The court had to weigh the probative value of the evidence against the potential prejudice to the appellant, and assess whether the similar fact evidence was sufficiently connected to the offences for which the appellant was being tried.

The court found that the trial judge had erred in ruling that the evidence was inadmissible, as it did not meet the criteria for similar fact evidence. The court held that the evidence of the commission of offences against one girl was relevant and probative in the case involving the other girl, and that the probative value of the evidence outweighed any potential prejudice to the appellant. The court concluded that the trial judge's ruling was incorrect, and that the evidence should have been admitted. As a result, the convictions on counts 1, 2, 3, 5, 6, 7, 8 and 10 were set aside with a direction for re-trial, while the application for leave to appeal against sentence was dismissed.

The court’s decision in this case underscores the importance of correctly applying the criteria for admitting similar fact evidence in sexual offence cases. The ruling highlights the need for careful consideration of the probative value and potential prejudice of such evidence, and the necessity of ensuring that the evidence is sufficiently connected to the offences for which the accused is being tried. The court's decision in this case will likely have implications for future cases involving similar fact evidence in sexual offence cases.
