The academic debate on officials within the EP only provides limited answers to the question under which conditions such actors have an impact on policy-making. We thus have to build on the more general debate on bureaucratic delegation processes to civil servants and work on ministerial bureaucracies. Any study on bureaucracy is-as our Research Master students in European Studies well know-inspired by Max Weber. The Weberian ideal type of a bureaucracy is characterized by hierarchical structures and the rule of law. Personnel of this ideal type are career officials recruited by way of "objective criteria and educational qualifications" (Barberis 2011, 15). These professionals adhere to principles of neutrality "free from all personal considerations" (Weber 1978, in: Barberis 2011, 962). From the debate on delegation in the US Congress we learn that competences are delegated to officials, given that clear administrative procedures and rules prevail. Administrative procedures lower the costs of monitoring and sharpen sanctions and thus contribute to greater compliance (McCubbins, Noll and Weingast. 1987, 246). Gailmard and Patty (2007) show that the risks of delegation can be minimized if issues are delegated to bureaucratic experts that have "some measure of control over policy issues they care about" and as such develop "politicized competence" (Gailmard and Patty 2007, 886). A merit system based on job tenure protections combined with discretion setting by the legislature, creates a main incentive for officials to invest in their career. These two factors provide a "payment" for expertise development (Gailmard and Patty 2007, 874-875). Politicized competence thus can be defined as the readiness to invest in "expertise development" and is not to be confused with politicization and partisanship (Peters and Pierre 2004). When trying to conceptualise the role officials play within policy-making, the work by Page and Jenkins (2005) is particularly instructive. Building on sociological theories of bureaucracy and drawing on 140 interviews, three types of policy roles of middle-level administrators working for UK ministries are identified (
