The respondent was convicted of second degree murder after an accomplice shot and killed a victim they had kidnapped for ransom.
The trial judge instructed the jury on constructive murder under s. 213(a) of the Criminal Code.
The Court of Appeal struck down s. 213(a) based on R. v. Vaillancourt and ordered a new trial.
The Supreme Court of Canada dismissed the Crown's appeal, holding that s. 213(a) violates ss. 7 and 11(d) of the Charter and is not saved by s. 1, for the reasons given in R. v. Martineau.
The Court also declined to apply the curative proviso, as a properly instructed jury would not necessarily have convicted the respondent.
