McIntosh v The State of Western Australia

The appellant, McIntosh, appealed against his conviction for murder and the sentence imposed by the Supreme Court of Western Australia. McIntosh was convicted for the murder of a man, alongside an accomplice. McIntosh argued that the trial judge caused a miscarriage of justice by informing the jury about the effect of section 37A of the Sentencing Act 1995 (WA) in relation to the accomplice's evidence, and by not directing the jury that the accomplice's previous guilty plea to the murder charge was not admissible evidence against McIntosh. McIntosh also argued that the sentence of life imprisonment with a non-parole period of 20 years was manifestly excessive and contravened the parity principle.

The court considered whether the trial judge's directions to the jury regarding the accomplice's evidence caused a miscarriage of justice. The court found that the trial judge's directions were not erroneous and did not cause a miscarriage of justice. The court held that the trial judge was entitled to inform the jury about the effect of section 37A of the Sentencing Act 1995 (WA) on the accomplice's evidence, as it was relevant to the weight to be given to that evidence. The court also found that the trial judge was not required to direct the jury that the accomplice's previous plea of guilty was not admissible evidence against McIntosh, as the plea was not evidence of the appellant's guilt. The court rejected McIntosh's argument that the sentence imposed on him was manifestly excessive and contravened the parity principle, finding that the sentence was within the range of appropriate sentences for the crime committed.

The Supreme Court of Western Australia dismissed McIntosh's appeal against his conviction and sentence. The court held that the trial judge did not occasion a miscarriage of justice by informing the jury of the effect of section 37A of the Sentencing Act 1995 (WA) or by failing to direct the jury that the accomplice's previous guilty plea was not admissible evidence against McIntosh. The court also found that the sentence imposed on McIntosh was not manifestly excessive and did not contravene the parity principle. McIntosh's appeal was dismissed, and his conviction and sentence were upheld.
