SBX v The Queen

The High Court of Australia considered an appeal by SBX against a conviction for murder. The dispute concerned the admissibility of certain evidence during SBX's trial, specifically evidence relating to a prior inconsistent statement made by a key prosecution witness.

The central legal issue before the High Court was whether the trial judge had erred in admitting the prior inconsistent statement of the witness into evidence. This involved determining whether the statement was admissible as evidence of the truth of its contents, or merely for the purpose of showing that the witness had made a prior inconsistent statement. The Court also considered the potential for unfair prejudice arising from the admission of such evidence.

The High Court held that the trial judge had erred in admitting the prior inconsistent statement as substantive evidence of the facts contained within it. The Court reaffirmed the principle that a prior inconsistent statement of a witness is generally admissible only to impeach the credit of the witness, not to prove the truth of the matters asserted in the statement, unless specific exceptions apply. In this instance, the Court found that the admission of the statement for its truth had created a substantial risk of unfair prejudice to the appellant, outweighing its probative value.

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