The appellant was convicted of two counts of second-degree murder after stabbing two strangers.
At trial, he did not contest the stabbings but claimed he intended to commit suicide.
On appeal, the appellant sought to introduce fresh psychiatric evidence indicating he suffered from catatonic schizophrenia at the time of the offences.
The Court of Appeal admitted the fresh evidence, finding it met the Palmer criteria.
Based on the unanimous and uncontradicted opinions of three forensic psychiatrists, the Court found the appellant established the defence of not criminally responsible on account of mental disorder.
The appeal was allowed, the convictions were set aside, and verdicts of not criminally responsible were substituted.
