This essay suggests that the accountability trends explored by Stian Øby Johansen and Gisela Hirschmann in their respective monographs should be viewed as indicating the emergence of a right to justification in global governance. Both Johansen and Hirschmann seek to advance the interdisciplinary conversation about the accountability of international organizations—Johansen by developing a normative framework assessing the quality of IO accountability mechanisms, and Hirschmann by seeking to identify the variables that shape the evolution of what she calls pluralist accountability. Building upon their analyses, I put forward a set of hypotheses about the procedural and substantive dimensions of the right to justification as well as the conditions for its consolidation in global governance.

In this article I press four different objections on Forst’s theory of the ‘Right to Justification’. These are (i) that the principle of justification is not well-formulated; (ii) that ‘reasonableness and reciprocity’, as these notions are used by Rawls, are not apt to support a Kantian conception of morality; (iii) that the principle of justification, as Forst understands it, gives an inadequate account of what makes actions wrong; and (iv) that, in spite of his protestations to the contrary, Forst’s account veers towards a version of moral realism that is prima facie incompatible with Kantian constructivism. I then evaluate Forst’s theory in the light of a distinction made by Sharon Street between restricted and unrestricted constructivism. I show that Forst has reason to deny that it is either the one or the other, but he is not able to show that it is both or neither. I conclude that the arguments Forst advances in support of his constructivist theory of the right to justification entail that it is a metaphysical and comprehensive conception in the relevant, Rawlsian sense. Forst’s theory of the right to justification therefore fails to fulfil one of the main stated aims.
