Maher v The Queen

The case of *Maher v The Queen* concerned an appeal to the High Court of Australia following a conviction for murder. The appellant, Maher, had been found guilty of murder by a jury in the Supreme Court of Queensland and sentenced to life imprisonment. The appeal to the High Court challenged the validity of that conviction.

The central legal issue before the High Court was whether the trial judge had erred in law by admitting evidence of the appellant's prior convictions. Specifically, the court had to determine if the admission of this evidence, which was presented by the Crown, was unfairly prejudicial to the appellant and therefore ought to have been excluded under the rules of evidence governing the admissibility of such material.

The High Court, in allowing the appeal, held that the admission of the prior convictions was indeed an error of law. The majority reasoned that the evidence of prior convictions was not relevant to any issue in the trial for the current murder charge, nor did it fall within any recognised exception to the general rule prohibiting the admission of evidence of bad character. The court emphasised that such evidence risked prejudicing the jury against the appellant, leading them to infer guilt based on past conduct rather than the evidence presented in relation to the present offence. The principles of a fair trial required that the jury consider only the evidence relevant to the charge before them.

Consequently, the High Court quashed the conviction and ordered a new trial.
