Betts v The Queen

Betts appealed his conviction for aggravated robbery to the High Court of Australia following a decision of the Supreme Court of Queensland. The central dispute concerned the admissibility of evidence obtained through a covert recording of the appellant in his prison cell.

The High Court was required to determine whether the admission of the covert recording, made in circumstances where the appellant had a reasonable expectation of privacy, constituted a miscarriage of justice. This involved considering the application of the common law exclusionary rule concerning improperly or illegally obtained evidence, and whether the circumstances of the recording warranted its exclusion.

The Court reasoned that while the recording was obtained in breach of the appellant's reasonable expectation of privacy, its admission did not necessarily occasion a miscarriage of justice. Applying the principles established in *Bannon v The Queen*, the Court held that the evidence was relevant and possessed significant probative value. The trial judge had properly considered the prejudicial effect of the evidence against its probative value and had given appropriate directions to the jury. Consequently, the High Court found no error in the admission of the evidence and dismissed the appeal.
