Hartwick v The Queen

In *Hartwick v The Queen*, the High Court of Australia considered an appeal by the applicant, Hartwick, 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 raised questions concerning the application of the rules of evidence, particularly those relating to the admissibility of character evidence and the potential for such evidence to prejudice the jury against the accused.

The High Court held that the admission of the evidence of prior convictions and bad character was improper and had occasioned a substantial miscarriage of justice. Brennan CJ, Dawson and Toohey JJ reasoned that the evidence was not relevant to any issue in the trial and was likely to have led the jury to infer guilt based on the applicant's past conduct rather than the evidence presented in relation to the charge of murder. The Court emphasised the importance of ensuring that convictions are based on evidence directly relevant to the offence charged, and that the prejudicial effect of character evidence must be carefully weighed against its probative value.

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