As discussed above, the rule of law was recognized in the Quebec Secession Reference53as one of four unwritten constitutional principles that are fundamental to the Canadian constitutional order.

In a series of references involving the setting of judicial salaries, the Court has cited the unwritten principle of the rule of law in support of its conclusion that a commission independent of the judiciary and the state should be able to make recommendations to the legislature about judicial salaries.56This decision resulted in strong criticism by some including La Forest J who argued in dissent that the Court should not resort to unwritten constitutional principles.57The Court also relied on unwritten constitutional principles in the Quebec Secession Reference discussed above.
In recent years, the Court has been more hesitant to rely on unwritten constitutional principles.
