Agius and The Queen

In *Agius and The Queen*, the High Court of Australia considered an appeal by the applicant, Agius, 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 and prior bad character. This evidence was admitted on the basis that it was relevant to establishing the applicant's propensity to commit the offence charged. The court was required to determine if this admission contravened the general rule against admitting such evidence, which is designed to prevent juries from convicting an accused on the basis of their past conduct rather than the evidence relating to the specific offence.

The High Court held that the admission of the evidence of prior convictions and bad character was an error. Their Honours applied the principle that evidence of an accused's prior convictions or bad character is generally inadmissible unless it has a specific relevance to an issue in the case, beyond merely showing a propensity to commit the crime. In this instance, the evidence did not possess such specific relevance and was therefore improperly admitted.

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