 A more recent strand to the question of the legal enforcement of morality is Rawlsian in origin, most notably the claim that constitutional essentials and matters of basic justice should be subject to a constraint of public reason (Section 7). An alternative perspective challenges the assumption that the limits of law is simply an evaluative question focussed on law as a neutral instrument put to good ends and bad. It takes the limits of law as in part a conceptual question. Law of its nature has an internal morality of its own, so it is claimed, with its own built-in limits (Section 8). A further question relates to the deployment by the law of techniques beyond coercion (Section 8).
