 The second approach takes features of individuals—their interests or their rights—as basic for legitimacy. At present, the most comprehensive contemporary philosophical treatment of international legitimacy of this kind is probably Allen Buchanan’s Justice, Legitimacy, and Self-Determination (2003). As mentioned above (section 2.2.), Buchanan advocates a moralized conception of legitimacy, according to which entities are legitimate if they are morally justified to wield political power. Specifically, political legitimacy requires that a minimal standard of justice is met.
