The appellant, Richard Pereira, was convicted of second degree murder in the death of Kathryn Horne.
At trial, the defence conceded that Pereira killed Horne, but argued he was not criminally responsible (NCR) due to mental disorder.
The Court of Appeal reviewed whether the trial judge erred in applying the NCR test, in analyzing post-offence conduct, and in considering expert evidence.
The appeal was dismissed, with the court finding no error in the trial judge’s approach to the NCR defence, the use of post-offence conduct, or the treatment of expert evidence.
