How do Commission officials conceive the Commission's role in the European Union? Should the Commission be the government of Europe or the servant of Member States? Is there a third possibility – that of institutional pragmatism, whereby Commission and Member States share authority? This article lays out jurisdictional options and role conceptions adopted by Commission officials, and estimates their relative incidence using a 2008 large-scale survey among Commission officials (N = 1,901). There is a plurality of views, though within relatively narrow parameters. In explaining variation, national background shapes views more than professional background.
