The Idea of Constitutional Pluralism

Constitutional discourse has perhaps never been more popular, nor more comprehensively challenged than it is today. The development of new constitutional settlements and languages at state and post-state level has to be balanced against the deepening of a formidable range of sceptical attitudes. These include the claim that constitutionalism remains too state-centered, overstates its capacity to shape political community, exhibits an inherent normative bias against social developments associated with the politics of difference, provides a language easily susceptible to ideological manipulation and, that, consequent upon these challenges, it increasingly represents a fractured and debased conceptual currency. A rehabilitated language of constitutionalism would meet these challenges through a version of constitutional pluralism. Constitutional pluralism recognises that in the post-Westphalian world there exists a range of different constitutional sites and processes configured in a heterarchical rather than a hierarchical pattern, and seeks to develop a number of empirical indices and normative criteria which allow us to understand this emerging configuration and assess the legitimacy of its development.
