Peters v The Queen

In *Peters v The Queen*, the High Court of Australia considered an appeal by the applicant, Peters, against his conviction for murder. The dispute centred on the admissibility of certain evidence during his trial.

The primary legal issue before the High Court was whether the trial judge had erred in admitting evidence of the applicant's prior convictions. Specifically, the court had to determine if this evidence was improperly used to suggest that the applicant had a propensity to commit criminal acts, thereby prejudicing the jury against him.

Dawson J, delivering the judgment, reasoned that evidence of prior convictions is generally inadmissible if its sole purpose is to establish a person's character or propensity to commit the crime charged. However, such evidence may be admitted if it has a relevant probative value for a purpose other than establishing propensity, such as demonstrating a common design or a particular system. In this instance, Dawson J found that the evidence of prior convictions was admitted without sufficient consideration of its potential prejudicial effect and its limited probative value for a purpose other than propensity. The court concluded that the admission of this evidence constituted a miscarriage of justice.

The High Court allowed the appeal, quashed the conviction, and ordered a new trial.
