Caffin v The Queen

In *Caffin v The Queen*, the High Court of Australia considered an appeal by the applicant, Caffin, against his conviction for conspiracy to import a prohibited import contrary to s 233B(1)(b) of the *Customs Act 1901* (Cth). The applicant had been convicted in the Supreme Court of New South Wales, and his appeal to the Court of Criminal Appeal of New South Wales was dismissed.

The central legal issue before the High Court was whether the trial judge had erred in law by admitting evidence of the applicant's prior convictions. Specifically, the court had to determine if the evidence of these prior convictions was relevant to proving the applicant's guilt in the present charge, or if it was merely evidence of his bad character, thereby prejudicing the jury against him.

Dawson J, delivering the judgment of the High Court, held that the evidence of prior convictions was not admissible to prove the applicant's guilt in the present offence. His Honour reasoned that the prior convictions did not demonstrate a common purpose or a particular modus operandi that was relevant to the conspiracy charge. The evidence was therefore inadmissible as it tended to show that the applicant was a person likely to commit such an offence, rather than proving that he actually committed the offence charged. The admission of this evidence was considered a material misdirection to the jury, which had the potential to cause a miscarriage of justice.

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