 Does the idea of constitutionalism require, as a matter of conceptual or practical necessity, the division of government powers urged by Montesquieu and celebrated by Americans as a bulwark against abuse of state power? In Regina’s case, there is no such separation: legislative, executive and judicial power all reside in her person. But how, it might be asked, can she be the one (qua judge) who determines whether her legislation satisfies the prescribed constitutional limitation? Even if, in theory, Regina’s constitution prohibits her from removing her constitutional restriction at will (because she must observe the 2/3rds meta-rule) can she not always choose to ignore her restrictions, or to interpret them so as to escape their binding force? Perhaps Bishop Hoadly was right when he said (1717) in a sermon before the English King: “Whoever hath an ultimate authority to interpret any written or spoken laws, it is he who is truly the Law-giver to all intents and purposes, and not the person who first wrote or spoke them.” (quoted in Gray 1986, p.12). Although some constitutional limits, e.g., the one which restricts the Mexican President to a single term of office, seldom raise questions of interpretation, many others (particularly those that concern civil rights) are ripe for such questions. Regina might argue that a decree requiring all shops to close on Sundays (the common Sabbath) does not concern a religious matter because its aim is a common day of rest, not religious observance. Others might argue, with seemingly equal plausibility, that it does concern a religious matter and therefore lies outside Regina’s legislative competence.
