Reg v Swaffield

In *Reg v Swaffield*, the High Court of Australia considered the appeal of a conviction for murder. The appellant, Swaffield, had been found guilty of murder by a jury in the Supreme Court of New South Wales. The central issue on appeal concerned the proper direction to be given to a jury regarding the defence of provocation.

The High Court was required to determine whether the trial judge's summing up to the jury on the issue of provocation was adequate and correctly stated the relevant legal principles. Specifically, the court had to consider whether 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 particular accused did in fact lose self-control.

The Court held that the trial judge's summing up was flawed. It was found that the judge had failed to adequately explain that the jury must consider whether the provocation was capable of causing an ordinary person to lose self-control, and that this was a question for the jury to determine. Furthermore, the judge had not sufficiently distinguished between the objective and subjective aspects of the defence. The High Court reiterated the principle that provocation, if established, reduces the crime of murder to manslaughter.

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