Abstract

How should international law’s role in determining international distributive outcomes, economic and otherwise, affect how we think about its legitimate authority? Domestic institutions’ legitimate authority in respect of distribution derives in large part from their concurrent roles in enabling security and coordination. Internationally, by contrast, functional disaggregation means that distribution must be legitimised in its own right. I begin by distinguishing the phenomenon of Distributive International Law, on which my argument focuses. I next introduce a number of wide instrumental accounts of legitimate authority, including Rawls’ Natural Duty account, Buchanan’s metacoordination view, and Williams’ political realism, showing how each understands legitimacy as an institution-level characteristic, allowing an institution’s success in one area to support its legitimacy in another where it may be less successful. This poses the question of how we distinguish amongst distinct institutions, which I answer by reference to the causal and constitutive (in)dependence amongst activities. This approach explains why distributive legitimacy does not arise as a separate question domestically: we cannot distinguish the state’s security and coordination activities from its distributive activities, so if the former are legitimate then so, ipso facto, are the latter. Internationally, by contrast, these mutual dependencies are limited, requiring that the legitimacy of distribution be established independently of other roles that international law plays.
