The appellant was convicted of three counts of first-degree murder for the deaths of his mother, aunt, and cousin.
At trial, he denied involvement, but his counsel advanced a defence of not criminally responsible (NCR) due to mental disorder.
The Crown called reply evidence from psychiatrists who had assessed the appellant under court order.
On appeal, the appellant challenged the constitutionality of the psychiatric assessment provisions, the jury instructions on the sequence of considering the NCR defence, the Crown's closing address, and the admission of evidence from a warrantless police entry into his apartment.
The Court of Appeal dismissed the appeal, finding that the constitutional challenge could not be raised for the first time on appeal due to a tactical decision at trial, the jury instructions did not constitute reversible error, and the warrantless entry was justified by exigent circumstances.
