The article examines recent theories of legal and constitutional pluralism, especially their adoption of sociological perspectives and criticisms of the concept of sovereignty. The author argues that John Griffiths's original dichotomy of “weak” and “strong” pluralism has to be reassessed because “weak” jurisprudential theories contain useful sociological analyses of the internal differentiation and operations of specific legal orders, their overlapping, parallel validity and collisions in global society. Using the sociological methodology of legal pluralism theories and critically elaborating on Teubner's societal (...) constitutionalism, the author subsequently reformulates the question of sovereignty as a sociological problem of complex power operations communicated through the constitutional state's organization and reconfigured within the global legal and political framework.
