The appellant was convicted of second degree murder following a fatal stabbing during a bar altercation.
At trial, the appellant raised self-defence and sought to introduce the deceased's criminal record and a transcript of a guilty plea to demonstrate the deceased's propensity for violence.
The trial judge excluded this evidence.
Furthermore, in response to a jury question, the trial judge instructed that 'recklessness' for murder meant foreseeing a 'risk' of death rather than a 'likelihood'.
The Court of Appeal held that the trial judge erred in excluding the propensity evidence and in the jury charge on recklessness.
The curative proviso was not applied, the appeal was allowed, and a new trial was ordered.
