Background
Warren Michael William Welton, a 55-year-old boarder in the complainant’s family home, was tried in the District Court at Brisbane on allegations involving the 13-year-old complainant. The prosecution alleged that in October 2023 he digitally penetrated her on two occasions and indecently touched her during the second incident.
In June 2025, a jury convicted Welton of two counts of rape and one count of unlawful and indecent treatment of a child under 16. He received three and a half years’ imprisonment. His sole appeal ground alleged a miscarriage of justice because the trial judge did not direct the jury on the permissible use of evidence that, before the charged incidents, Welton had grabbed the complainant’s wrists, touched or grazed her waist, and stared or smiled at her in a way she described as creepy.
Although the prosecutor initially characterized the earlier contact as narrative or contextual evidence rather than evidence of sexual interest, her closing address argued that Welton had been “testing the waters” to learn how the complainant would react before escalating to the charged conduct. The trial judge repeated the prosecution’s escalation theory when summarizing its case but, consistently with both counsel’s submissions, gave no specific direction restricting the jury’s use of the evidence.
The Court’s Holding
The Court of Appeal unanimously allowed the appeal. Smith J, with Bond JA and Doyle JA agreeing, held that the prosecution’s use of the earlier conduct invited the jury to infer that Welton had a sexual interest in the complainant and was the kind of person likely to commit the charged offences. Taken together with the evidence of creepy staring and “weird vibes,” the evidence created a real risk of impermissible propensity reasoning.
The trial judge therefore should have directed the jury that the evidence was admitted only as narrative evidence, could not be used as proof of sexual motive or interest, and could not support reasoning that Welton was the type of person who would commit the charged offences. The responsibility to ensure a fair trial remained with the judge even though defence counsel had not requested such a direction.
The omission could realistically have affected the jury’s reasoning and tipped the balance toward conviction. The prosecution had emphasized the “testing the waters” theory, the judge repeated it, the complainant’s account lacked corroborating evidence, and other boarders had observed nothing of the alleged offending. The Court set aside all three guilty verdicts and ordered a new trial.
Key Takeaways
- Evidence presented as background or narrative may require a limiting direction when the prosecution’s argument invites the jury to use it as proof of sexual interest or propensity.
- In a sexual-offence trial, jurors ordinarily must be warned not to infer guilt merely because an accused allegedly engaged in earlier conduct suggesting a reprehensible tendency.
- A trial judge’s duty to ensure a fair trial may require such a direction even when neither prosecution nor defence counsel requests it.
Why It Matters
The decision underscores that the practical use made of evidence at trial—not merely the label assigned to it—determines whether a propensity warning is needed. A prosecutor cannot characterize earlier conduct as context while inviting jurors to treat it as a deliberate prelude to the charged sexual offending without creating a risk of impermissible reasoning.
For trial judges and counsel, the case highlights the need to reassess jury directions after closing submissions. When an address gives ostensibly narrative evidence a tendency-based significance, a tailored limiting direction may be essential to prevent a miscarriage of justice.
