Thus, despite the importance of interpretation in Dworkin’s work, his focus is on the theory of law, not on legal interpretation as it is understood here. He seems to take for granted that there is little or no space between a theory of law and a theory of legal interpretation. (On the issue of how such theories may come apart, see section 5.2.) Consequently, he assumes that, if he is right that the content of the law is constitutively determined by constructive interpretation, then the best way to ascertain a provision’s contribution is to ask which principles best fit and justify the enactment or ratification of the provision.
