The appellants, a mother and son, were convicted of first-degree murder in the death of the mother's husband.
The son admitted to killing the deceased but claimed self-defence, defence of his mother, or provocation, citing a history of severe domestic abuse by the deceased.
The Crown's theory was that the appellants conspired to kill the deceased for insurance money.
On appeal, the appellants argued that the trial judge erred in his jury instructions regarding self-defence, party liability, the use of co-accused statements, the standard of proof for reasonable doubt, and the need for a Vetrovec warning for unsavoury Crown witnesses.
The son also argued the Crown's cross-examination was abusive.
The Court of Appeal dismissed the appeals, finding no reversible errors in the jury charge and concluding that the cross-examination, while aggressive, did not compromise trial fairness.
