Beyond Constitutionalism: The Pluralist Structure of Postnational Law. As I note in my review essay, Krisch’s book revolves around the question how best to deal with postnational law, that is characterized by a proliferation of international organizations and fields of international law in which states lose more and more of their sovereignty. This process of internationalization puts strains on democratic decision-making processes at the national level and could potentially lead to alienation from the international legal order of both states and their citizens. How should this problem of an ever-growing messiness at the international level be addressed from a legal perspective? And what should be the relationship between the legal orders – international, regional and national – that are part of this constellation of postnational law? With his plea for radical pluralism Krisch has positioned himself at the far-end of the spectrum in the debate that flows from these questions. His view constitutes a break with the constitutionalist approach, which aims for a transfer of the qualities of national legal systems – such as a clear hierarchy and enforcement mechanisms of legal rules – to the international level. Krisch aims for an international legal order which is founded on a pluralism that ‘eschews ultimate authority and overarching conflict norms’, in which also the nature of the relationship between the different suborders is principally unsettled.
