In 2000, the BC government sued 14 "tobacco manufacturers" pursuant to the Tobacco Damages and Health Care Costs Recovery Act. The Tobacco Companies challenged the constitutionality of the legislation, alleging amongst other things that the Tobacco Act violated the rule of law. In this paper, I begin by showing that the Supreme Court of Canada adopts a formal approach to the rule of law devoid of much substantive content. This, I argue, is in line with the views of Joseph Raz. I then argue that the Tobacco Companies' reliance on Raz's views for support in its claim that the Tobacco Act violates the rule of law is misguided. Far from invalidating the Tobacco Act, Raz's view can be understood to license it. In the last section of the paper, I show that a formal approach to the rule of law such as Raz's does not confine Charter interpretation.
