The appellants were convicted of offences relating to the death of their eight-month-old son, who was found to have suffered extensive physical abuse during his life.
The father was convicted of second-degree murder and assaults, while the mother was convicted of criminal negligence causing death and failing to provide the necessaries of life.
On appeal, they argued the verdicts were unreasonable because the exact medical cause of death could not be determined, and challenged the admission of demeanour evidence, evidence of injuries to their second child, and various jury instructions.
The Court of Appeal dismissed the appeals, finding that the Crown was not required to prove a specific medical cause of death, and that while there were minor errors in the admission of evidence and jury instructions, they did not occasion a substantial wrong or miscarriage of justice given the overwhelming evidence of ongoing abuse.
