Croll v The Queen

In *Croll v The Queen*, the High Court of Australia considered an appeal by the applicant, Croll, 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 convictions of a co-accused. This evidence was admitted on the basis that it was relevant to the question of whether the applicant had a propensity to commit the offence charged.

Gummow and Kirby JJ held that the admission of this evidence was an error. Their Honours applied the principle that evidence of prior convictions is generally inadmissible to prove a propensity to commit the crime charged, as it is unfairly prejudicial to the accused. The court reasoned that such evidence could lead the jury to infer guilt based on past behaviour rather than on the evidence relating to the specific offence before them. The appeal was allowed, and a new trial was ordered.
