To explain the passing of the first directive, the MSA is (a) expanded from agenda-setting to the actual decision-making by introducing a second coupling process, and (b) adapted to the European level. The first coupling process explains how the liberalization issue could gain agenda-status although almost all veto players opposed this idea. The second coupling process with a focus on the actual decision-making allows to analyze precisely the strategies applied by policy entrepreneurs in order to gain the majorities needed for passing the directive. As the main explanation for the subsequent regulatory activity and shortened legislative process lies in the inception and dynamics of the policy community, a refinement of this concept within the MSA is introduced that facilitates analysis. Empirically, the analysis is based on primary materials, in particular legislative documents, and secondary sources such as media reporting and information gathered from the European Public Affairs Directory. Thereby the establishment of the policy community is illustrated with particular emphasis on its main centerpiece, the European Gas Regulatory Forum. The analysis of its achievements is followed by a discussion of the success of this forum in fostering consensus. The paper closes with a discussion of the lessons that can be learned for solving coordination problems in the European context.
