The appellant appealed his conviction for the sexual assault of his stepdaughter.
At trial, the Crown called a clinical and forensic psychologist to address frailties in the complainant's evidence, including delayed disclosure and memory issues.
The trial judge relied heavily on this expert opinion to find the complainant credible.
However, the tape of the expert's cross-examination was lost before it could be transcribed.
The Court of Appeal held that the missing transcript prevented a proper assessment of whether the trial judge erred in her use of the expert evidence, raising serious concerns about the safety of the verdict.
The appeal was allowed and a new trial ordered.
