Ronald Dworkin has shown that the doctrine of judicial self-restraint, although packaged as a defense of constitutional tradition, is grounded in a legalmoral skepticism that either inadvertently or covertly rejects the possibility of a genuinely normative constitution. The influence of Dworkin's argument challenges exponents of judicial self-restraint to show that their position is consistent with constitutionalist assumptions. This paper considers two attempts to meet that challenge. One defends restraint on epistemologieal grounds; the other on a substantive theory of natural rights. Together, these attempts constitute a comprehensive and systematic attempt to justify restraint within constitutionalist assumptions. Their failure indicates that the doctrine of restraint can form no part of a normative theory of the Constitution.
