As we saw above, Dworkin’s theory makes normative arguments relevant. But the type of normative argument that it makes relevant is very different from the normative arguments typically offered in favor of theories of legal interpretation. On Dworkin’s theory, the way to show that a method of interpretation accurately identifies how sources, such as statutory and constitutional provisions, contribute to the law is to show that the method yields the principles that best justify the enactment of those provisions. An argument that a method yields the best justification of enactments is, however, very different from the kind of normative argument typically offered in favor of theories of legal interpretation.
