Who consults? The configuration of expert groups in the European union (in Special Issue: Towards a New Executive Order in Europe?)

Abstract: This article examines and explains the committee system of the EU as a crucial property of the EU governance system using a database on the European Commission's experts groups. What is the extent of the expert consultative system? What is the distribution of expert groups? Are these groups best understood as loose networks or do they constitute a stable, well-established consultative system? We observe a proliferation of expert groups over time and across sectors. They have become permanent properties of the EU governance system; yet they are remarkably unevenly distributed among different policy domains. Sectoral differentiation is accentuated by weak horizontal coordination between the Directorates-General. We argue that this heterogeneity is not only a result of deliberate design attempts and differences in policy tasks, but also the result of differences in legal and administrative capabilities, as well as the gradual development of different routines and norms among the DGs.
