Banditt v The Queen

The case of *Banditt v The Queen* concerned an appeal to the High Court of Australia by the applicant, Banditt, against his conviction for murder. The applicant had been found guilty of murder by a jury in the Supreme Court of New South Wales and subsequently sentenced to imprisonment. The appeal to the High Court raised questions regarding the fairness of the trial and the admissibility of certain evidence.

The central legal issue before the High Court was whether the trial judge had erred in admitting evidence of the applicant's prior convictions and prior bad character. Specifically, the court had to consider whether this evidence was relevant to the charge of murder and, if so, whether its prejudicial effect outweighed its probative value, thereby rendering its admission unfair and unsafe. The applicant argued that the admission of this evidence had unfairly prejudiced his defence and led to a miscarriage of justice.

In its reasoning, the High Court examined the principles governing the admission of evidence of prior convictions and bad character in criminal trials. The court affirmed that such evidence is generally inadmissible unless it possesses a sufficient degree of relevance to a fact in issue in the current proceedings, beyond merely demonstrating a propensity to commit crime. The court found that the evidence admitted in this case did not meet the required threshold of relevance and was therefore improperly admitted. Consequently, the High Court concluded that the admission of this evidence had created a substantial risk of unfair prejudice to the applicant, rendering the conviction unsafe.

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