Toby Quinn (a pseudonym)[1] v The Queen

The case of Toby Quinn (a pseudonym) v The Queen involves an appeal against a conviction for sexual penetration of and indecent acts with a child under 16, along with other misconduct. The court addressed the admissibility of text messages exchanged between the appellant and the complainant and the failure of the trial judge to provide an anti-propensity warning as required by the Jury Directions Act 2015. The appellant argued that the admission of the text messages led to a substantial miscarriage of justice because it allowed the jury to infer a sexual relationship between the appellant and the complainant, which was not directly relevant to the charges. The appeal was heard in the Victorian Court of Appeal.

The legal issues before the court included whether the trial judge was required to give a warning about the potential for propensity reasoning when admitting the text messages and whether the failure to do so constituted a substantial miscarriage of justice. The court also needed to determine whether the convictions on specific charges should stand or if a new trial was necessary. The admissibility of the text messages under sections 97 and 101 of the Evidence Act 2008 was another significant point of contention, with arguments centring on whether the prosecution had invoked tendency reasoning by using the messages to demonstrate a sexual relationship.

The court found that neither defence counsel nor the prosecutor requested the trial judge to give an anti-propensity warning regarding the text messages, but concluded that there were substantial and compelling reasons for such a direction to be given. The failure to provide the warning resulted in a substantial miscarriage of justice, leading to the upholding of the second ground of appeal. The convictions on charges 2, 3, 4, 5, and 6 were deemed to be unsustainable, necessitating a new trial on those charges. However, the conviction on charge 1 was considered inevitable. The court also addressed the admissibility of the text messages, finding that the prosecution's use of the messages constituted tendency reasoning, and thus, the evidence should have been subject to the safeguards provided by sections 97 and 101 of the Evidence Act.
