GBF v The Queen

The appellant, GBF, was convicted in the Supreme Court of Queensland on seven counts of sexual offences allegedly committed against his half-sister when she was between 13 and 14 years old. The prosecution's case relied entirely on the complainant's evidence, and the appellant did not give or call evidence at trial. The appeal concerned the trial judge's directions to the jury, specifically a statement made after initial directions regarding the presumption of innocence and the onus and standard of proof.

The central legal issue before the High Court of Australia was whether the trial judge's impugned statement, that the appellant's failure to give sworn evidence "may make it easier" to assess the complainant's credibility, occasioned a miscarriage of justice. This required the Court to consider whether the statement invited the jury to impermissibly reason to the appellant's guilt from his exercise of the right to silence, and whether the influence of this statement was diminished by it being a judicial observation on the facts rather than a direction of law. The Court also had to consider whether the failure of either counsel to seek a redirection from the trial judge weighed against a conclusion that the trial's integrity was compromised, and whether the ambiguity of the statement meant there was no reasonable possibility the jury would have reasoned impermissibly.

The High Court allowed the appeal, finding that the impugned statement created a real chance that the jury would have engaged in a false process of reasoning, drawing an inference of guilt from the appellant's silence. Their Honours held that the statement, by suggesting that the absence of the appellant's evidence could assist in assessing the complainant's credibility, undermined the fundamental principle that an accused is not required to prove their innocence and that their silence cannot be used as evidence against them. The Court concluded that this irregularity, despite the absence of a redirection application, compromised the integrity of the trial and constituted a miscarriage of justice. Consequently, the convictions were set aside, and a new trial was ordered.
