Warner v The Queen

In *Warner v The Queen*, the High Court of Australia considered an appeal by the applicant, Warner, 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 certain statements made by him to police. This evidence was admitted on the basis that it was relevant to the applicant's propensity to commit the offence charged.

The High Court held that the admission of evidence of prior convictions and the statements made to police was an error. Brennan, Deane and Dawson JJ reasoned that such evidence was not relevant to proving the commission of the offence charged, but rather served to demonstrate the applicant's bad character and propensity to commit offences. This, they found, was contrary to the principle that evidence of prior convictions is generally inadmissible to prove guilt of a subsequent offence, unless it possesses a specific probative value beyond mere propensity. The court affirmed that the onus was on the prosecution to demonstrate that the evidence had a relevance that outweighed its prejudicial effect.

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