Bill Davies
Department Chair
Dr. Davies is approaching the study of the European Union legal system from a fresh perspective by critically examining the development of the constitutional practice of law in the EU from a historical perspective. Dr. Davies has traveled extensively to uncover the primary documents that will contribute to a fresh and empirically accurate narrative of the emergence of the European constitutional system and to answer the question of how the controversial consolidation of power at the European level has been received in the EU’s member states.
