  The immediate source of the difficulties lies in the composite character of the ideal of principled consistency deployed by hybrid interpretivism, which entails that the interpreter must simultaneously aim at consistency and merit, understood as separate targets which needn’t coincide. Given the difficulties, it is unclear that interpretation could secure completeness, understood as the potential to resolve all possible disputes (which is often understood to be interpretation’s further, perhaps basic objective; see Raz 1994; Finnis 1987; see also Leiter 2007, who claims that the thesis that there is a right answer to all legal questions is at the core of Dworkin’s project). The composite conception of principled consistency is forced upon hybrid interpretivism by its fundamental commitment, to which the difficulties are ultimately traced: that the starting point of interpretation must be some norms constituted by the contingencies of institutional communication, and that interpretation’s purpose is to compare and somehow to reconcile those norms with ideals.
