Palmer v The Queen

In *Palmer v The Queen*, the High Court of Australia considered an appeal by the applicant, Palmer, against his conviction for murder. The applicant had been found guilty of murder by a jury in the Supreme Court of Queensland and subsequently sentenced to life imprisonment. The appeal to the High Court concerned the interpretation and application of the law relating to provocation as a defence to murder.

The central legal issue before the High Court was whether the trial judge had erred in directing the jury on the defence of provocation. Specifically, the court had to determine whether the judge's directions adequately explained the elements of provocation, particularly the requirement that the provocation must be such as to cause an ordinary person to lose self-control and act as the accused did. This involved considering the objective and subjective elements of the provocation defence.

The High Court, in a joint judgment, held that the trial judge's directions were inadequate. Their Honours explained that the defence of provocation requires the jury to consider whether the provocation was sufficient to cause an ordinary person to lose self-control and to act in the way the accused did. This involves a two-stage test: first, whether the provocation was such as to cause an ordinary person to lose self-control, and second, whether the accused did in fact lose self-control and act as a result of that provocation. The court found that the jury had not been properly instructed on the objective element of the test, which requires an assessment of the reaction of an "ordinary person" to the alleged provocation.

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