While there have been numerous recent analyses of the legitimacy of suprastate governance institutions such as the World Trade Organization (WTO) or United Nations Security Council, few accounts have considered individual duties in relation to those institutions, broadly analogous to suprastate political obligation. Identified in this chapter are three categories of duties that should be salient to a range of institutions. These include duties to support their reform, to resist specific institutional features or practices, and to reject the continued operation of some institutions and support the creation of alternate ones. These duties would correspond roughly to how well an institution would appear to fit into a global institutional scheme that actually would fulfill cosmopolitan aims for rights promotion and protections and related global moral goods. An implication is that the current global system itself is a candidate for rejection, given its inherent tendencies toward the gross underfulfillment of individual rights.
