Nicholson v The Queen

In *Nicholson v The Queen*, the High Court of Australia considered an appeal by the applicant, Nicholson, against his conviction for murder. The applicant had been found guilty by a jury in the Supreme Court of Queensland and subsequently appealed to the Court of Criminal Appeal of Queensland, which dismissed his appeal. The matter then proceeded to the High Court.

The central legal issue before the High Court was whether the trial judge had erred in law by failing to adequately direct the jury on the defence of provocation. Specifically, the court had to determine if the jury had been properly instructed on the objective elements of provocation, namely whether the provocation was such as to cause an ordinary person to lose self-control, and the subjective elements, namely whether the applicant himself had in fact lost self-control.

Deane and Gaudron JJ, in their joint judgment, found that the trial judge's summing up had been deficient in its explanation of the objective test for provocation. They held that the jury had not been sufficiently guided to consider whether the provocation was of a kind that could have caused an ordinary person to act as the applicant did. The judges emphasised that for the defence of provocation to succeed, it must be established that the provocation was sufficient to cause an ordinary person to lose self-control, and that the accused person did, in fact, lose self-control as a result of that provocation. The failure to properly articulate this dual test meant that the jury may not have properly considered the available defence.

The High Court allowed the appeal, quashed the conviction for murder, and ordered a new trial.
