Jacob Turner (a pseudonym)[1] v The Queen

Jacob Turner, appealing against his criminal conviction and sentence, sought leave to appeal to the High Court. Turner had pleaded guilty to raping the intellectually disabled daughter of his de facto partner. The court was tasked with deciding whether the primary judge had erred in characterising Turner’s actions as an act of commission rather than omission, and whether Turner's state of mind – not considering whether the complainant was consenting – reduced his culpability. The High Court needed to determine if the sentence was a manifest excess of judicial discretion.

Turner argued that the primary judge had mischaracterised his actions by treating the offence as an act of commission rather than an omission, which could have impacted the severity of the sentence. Turner further contended that his state of mind, which involved not giving any thought to the complainant's ability to consent, should have rendered him less culpable. The High Court considered whether these arguments were sufficient to show that the sentence was manifestly excessive, warranting leave to appeal.

The High Court found that Turner’s arguments did not establish a substantial miscarriage of justice or that the sentence was manifestly excessive. The court held that Turner’s failure to consider the complainant's capacity to consent did not significantly mitigate his culpability, and the sentence was within the appropriate range for such a serious offence. Consequently, the High Court refused Turner’s application for leave to appeal.
