R v Ogunseye

The appellant was convicted on one count of rape and brought an appeal against his conviction to the NSW Court of Criminal Appeal. The primary issue for the court to decide was whether there was a misdirection by the trial judge that led to a miscarriage of justice. The appellant argued that the trial judge erred in the direction given to the jury in relation to the prosecution's attack on the credit of the expert witness. The expert, a linguistics professor of Yoruba ethnicity, provided evidence that the appellant's apology in the pre-text telephone conversations was not an admission of guilt but an attempt to pacify the complainant. The court had to consider whether the trial judge's direction aligned with the applicable legal principles and whether this misdirection resulted in a miscarriage of justice.

The court considered the trial judge's direction to the jury and the principles outlined in Benchbook Direction 43 concerning bad character and previous convictions. The court found that the direction given did not adequately address the specific nature of the expert's evidence and the attack on their credit. The court held that the trial judge did not sufficiently explain to the jury how they should consider the prosecution's attack on the expert's credibility in relation to the specific evidence provided. This misdirection was significant because it undermined the integrity of the expert's testimony, which was central to the defence's case. The court concluded that the misdirection had a substantial and significant influence on the outcome of the trial, amounting to a miscarriage of justice.

Consequently, the appeal was allowed, and the conviction was set aside. The court ordered a retrial to ensure that the appellant had a fair chance to present his defence. This decision underscores the importance of accurate and comprehensive judicial directions in criminal trials, particularly when expert evidence is central to the defence's case. The court's ruling highlights the need for careful consideration of the specific context and nature of expert evidence when addressing attacks on the credibility of expert witnesses.
