The case provides a comprehensive application of the principles governing propensity evidence under s 31A of the Evidence Act 1906 (WA) in multi-complainant child sexual offence trials, confirming that 'striking similarity' or 'underlying unity' are not required for admissibility. It also confirms that mixed verdicts (guilty on some counts, not guilty on others relating to the same complainant) are not inconsistent but rather demonstrate careful jury deliberation. The case reaffirms that the test for miscarriage of justice based on incompetent counsel focuses on the effect on the trial, not the quality of counsel's performance.
