Adams (a pseudonym) v The Queen; Bradley (a pseudonym) v The Queen

In *Adams (a pseudonym) v The Queen* and *Bradley (a pseudonym) v The Queen*, the Court of Appeal of the Supreme Court of South Australia considered appeals against convictions for offences related to a home invasion. The prosecution's case relied on the evidence of an accomplice, Mr Daley, who testified about the appellants' involvement in the planning and execution of the offences, supported by circumstantial evidence. The central dispute on appeal concerned the admission of evidence relating to the first appellant's brother's membership in an outlaw motorcycle gang and its potential prejudicial effect on the jury.

The legal issues before the Court were whether the trial judge erred in admitting the evidence of the first appellant's brother's gang membership, whether this admission created a significant risk of unfair prejudice to the appellants, and if so, whether this risk was outweighed by the evidence's probative value. Additionally, the Court had to determine if the trial judge erred in refusing to declare a mistrial or withdraw the evidence, and whether the directions given to the jury regarding the use of this evidence were adequate to prevent a miscarriage of justice.

The Court reasoned that the impugned evidence was relevant to establishing the appellants' connection to the plan and the motive for retrieving vehicles, particularly as Mr Daley testified that the plan was initiated at the request of the first appellant's brother, who was his superior in the motorcycle club. The Court found that the trial judge's directions to the jury on the permissible and impermissible uses of this evidence were clear, correct, and comprehensive, effectively mitigating any potential for unfair prejudice. Consequently, the Court concluded that there was no miscarriage of justice and dismissed the appeals.
