The appellant, Cindy Ali, appealed her conviction for first-degree murder in the death of her profoundly disabled daughter.
The Crown alleged the appellant suffocated her daughter and fabricated a home invasion story to cover it up.
The defence argued the death was seizure-related or caused by a home invader, and that the home invasion was real.
The Court of Appeal found that the trial judge erred in narrowing the jury's consideration of the cause of death to only suffocation and in unduly restricting the jury's consideration of alternative explanations for the fabricated home invasion narrative.
The trial judge's instructions effectively invited the jury to convict of murder if they found the home invasion story fabricated, without adequately considering other culpable acts (like failure to provide necessaries) or innocent explanations for the fabrication.
The appeal was allowed, the conviction set aside, and a new trial ordered.
