Postiglione v The Queen (Ss63-98) SLA

The High Court of Australia considered an appeal by the applicant, Postiglione, against a decision of the Supreme Court of South Australia. The dispute concerned the applicant's conviction for murder and the subsequent dismissal of his appeal by the Full Court of the Supreme Court of South Australia.

The primary legal issue before the High Court was whether the trial judge had erred in law by failing to direct the jury on the defence of provocation. Specifically, the court had to determine if there was sufficient evidence presented at trial to raise an issue of provocation, thereby necessitating a direction to the jury.

The High Court analysed the evidence adduced at trial, particularly concerning the events leading up to the deceased's death. Their Honours considered the legal test for provocation, which requires evidence of a loss of self-control induced by a sudden or temporary loss of reason, and that the act of killing was a response to that provocation. Gummow and Hayne JJ concluded that, on the facts presented, no reasonable jury, properly instructed, could have found that the applicant acted under provocation. Therefore, the trial judge was not obliged to direct the jury on this defence. The appeal was dismissed.
