Chieu v The Queen

In *Chieu v The Queen*, the High Court of Australia considered an appeal from a conviction for murder. The appellant, Chieu, had been found guilty of murder by a jury in the Supreme Court of New South Wales and subsequently appealed to the Court of Criminal Appeal of New South Wales, which dismissed his appeal. The High Court granted special leave to appeal from the decision of the Court of Criminal Appeal.

The central legal issue before the High Court was whether the trial judge had erred in law by failing to direct the jury adequately on the issue of self-defence, specifically concerning the appellant's subjective belief as to the necessity of using force. The appeal also raised questions regarding the proper application of the principles governing the admissibility of evidence of prior consistent statements.

The High Court, in allowing the appeal and ordering a new trial, held that the trial judge’s summing up had failed to properly convey to the jury the subjective nature of the appellant's belief regarding the need to use force in self-defence. Their Honours emphasised that the jury was required to consider whether the appellant genuinely believed that the force he used was necessary, irrespective of whether that belief was reasonable. The Court reiterated that for a defence of self-defence to be established, the accused must have acted in defence of themselves or another, and that the force used must have been a reasonable response to the circumstances as the accused perceived them. The Court also addressed the admissibility of prior consistent statements, noting that such statements are generally inadmissible to bolster credibility unless an issue has been raised as to recent fabrication.

The High Court ordered that the appeal be allowed, the conviction be quashed, and a new trial be held in the Supreme Court of New South Wales.
