It is common to encounter the criticism that Joseph Raz’s service conception of authority is flawed because it appears to justify too much. This essay examines the extent to which the service conception accommodates this critique. Two variants of this critical strategy are considered. The first, exemplified by Kenneth Einar Himma, alleges that the service conception fails to conceptualize substantive limits on the legitimate exercise of authority. This variant fails; Raz has elucidated substantive limits on jurisdiction within the service conception (...) of authority, albeit reluctantly and equivocally. The second, exemplified by Scott Hershovitz, alleges that the service conception fails to conceptualize procedural limits on the legitimate exercise of authority. He objects that the normal justification thesis fails to deny legitimacy to rational and expert dictators. This argument is more potent, but its force is concealed when it is aimed at the normal justification thesis rather than the quite separate jurisdictional limits of Raz’s theory. Clarifying those jurisdictional aspects of the service conception shows why the first argument fails and exposes the real strength of the second. Both variants have important consequences for our understanding of the service conception. (shrink)

According to Joseph Raz's sources thesis, the existence and content of authoritative directives must be identifiable by resort to the social fact of their provenance from a de facto authority, without regard to any of the normative considerations that the authority in question is supposed to rely on in its judgment. This article argues that the sources thesis fails to account for the role of jurisdictional considerations (namely, considerations about the scope of a de facto authority's power) in the identification (...) of valid law. It examines a legal system with a legislature and courts and a practice of constitutional review of legislation by the courts for its conformity with fundamental rights and argues that the special normative status of (at least some) authoritative directives in this legal system depends on respect for jurisdiction. An assessment of whether an authority has stayed intra vires involves recourse to the normative considerations that it is the authority's job to weigh up. This criticism of the sources thesis highlights the importance of incorporating jurisdiction into our philosophical accounts of legal authority. (shrink)
