Cheung v The Queen

In *Cheung v The Queen*, the High Court of Australia considered an appeal from a conviction for armed robbery. The appellant, Cheung, had been found guilty by a jury and sentenced to a term of imprisonment. The appeal concerned the admissibility of certain evidence and the fairness of the trial process.

The central legal issue before the High Court was whether the trial judge had erred in admitting evidence of a prior inconsistent statement made by a key prosecution witness. This statement, made to police shortly after the alleged offence, differed in material respects from the witness's testimony at trial. The appellant argued that the admission of this statement, without adequate directions to the jury regarding its use, had prejudiced his defence.

The High Court, in allowing the appeal, held that the trial judge had misdirected the jury concerning the use of the prior inconsistent statement. While such statements may be admissible for the purpose of undermining the credit of a witness, they are generally not admissible as evidence of the truth of their contents unless specific exceptions apply. The Court found that the jury had not been sufficiently cautioned that the statement could not be used as proof of the facts it asserted, thereby creating a risk that they would treat it as substantive evidence against the appellant. This failure to provide adequate directions constituted a miscarriage of justice.

Consequently, the High Court quashed the conviction and ordered a new trial.
