Underlying the CBB's approach in paragraph MIE-3.1.8 is the fundamental principle of proportionality. The enforcement measures contained in this Module are of varying severity, and will be used accordingly in keeping with the CBB's assessment of the contravention. Thus, the CBB will reserve its most serious enforcement measures — such as initiating prosecution for imposing criminal sanctions, cancellation of license or withdrawal of "fit and proper" status — for the most serious contraventions.
