Lumley v The Queen

In *Lumley v The Queen*, the High Court of Australia considered an appeal by the applicant, Lumley, against his conviction for armed robbery. The dispute arose from the applicant's assertion that the trial judge had erred in admitting evidence of a prior conviction for a similar offence.

The central legal issue before the High Court was whether the evidence of the applicant's prior conviction was admissible under the tendency limb of section 97 of the *Uniform Evidence Law* (or equivalent legislation in the relevant jurisdiction). Specifically, the court had to determine if the evidence was relevant to prove a fact in issue in the current proceedings, namely that the applicant had a propensity to commit armed robberies, and if its probative value outweighed its prejudicial effect.

The High Court held that the evidence of the prior conviction was not admissible under the tendency limb. Their Honours reasoned that for evidence to be admissible under this limb, there must be a sufficient degree of relevance to establish a tendency to commit the offence charged. In this instance, the similarities between the prior offence and the current offence were not so striking as to demonstrate a specific tendency or pattern of behaviour that made it more probable that the applicant committed the offence charged. The court emphasised that the prejudicial effect of admitting evidence of a prior conviction, particularly for a similar offence, is significant and must be carefully weighed against its probative value.

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