Abstract

The complexity of the relationship between democracy and modern constitutionalism is revealed by treating democracy as an incomplete ideal. This refers both to the empirical incompleteness of democracy as unable to supply its own terms of application – the internal dimension – and to the normative incompleteness of democracy as guide to good government – the external dimension. Constitutionalism is a necessary response to democratic incompleteness – seeking to realize and to supplement and qualify democracy . How democratic incompleteness manifests itself, and how constitutionalism responds to incompleteness evolves and alters, revealing the relationship between constitutionalism and democracy as iterative. The paper concentrates on the iteration emerging from the current globalizing wave. The fact that states are no longer the exclusive sites of democratic authority compounds democratic incompleteness and complicates how constitutionalism responds. Nevertheless, the key role of constitutionalism in addressing the double incompleteness of democracy persists under globalization. This continuity reflects how the deep moral order of political modernity, in particular the emphasis on individualism, equality, collective agency and progress, remains constant while its institutional architecture, including the forms of its commitment to democracy, evolves. Constitutionalism, itself both a basic orientation and a set of design principles for that architecture, remains a necessary support for and supplement to democracy. Yet post-national constitutionalism, even more than its state-centred predecessor, remains contingent upon non-democratic considerations, so reinforcing constitutionalism’s normative and sociological vulnerability. This conclusion challenges two opposing understandings of the constitutionalism of the global age – that which indicts global constitutionalism because of its weakened democratic credentials and that which assumes that these weakened democratic credentials pose no problem for post-national constitutionalism, which may instead thrive through a heightened emphasis on non-democratic values
