Decision-making dynamics in the European Commission: partisan, national or sectoral?

Abstract: Its monopoly power to formulate policy proposals and set the European Union's (EU's) legislative agenda guarantees the European Commission considerable prominence in EU legislative studies. It is commonly conceptualized as a unitary actor, acting cohesively - often in its own supranational interest - in EU decision-making. Recent theoretical developments and empirical studies, however, cast doubt on this conceptualization. This paper takes up these matters and investigates the decision-making mechanisms and dynamics of the Commission's executive politics. Two case studies show that the formal division of power along portfolios puts formally responsible Commissioners in a privileged position to influence the content of legislative proposals in internal decision-making. This influence, however, is circumscribed by the opposition of other Commissioners. At least in the cases studied here, Commissioners' position-taking and conflict in internal decision-making follow a national and, to some extent, a sectoral rather than a partisan pattern.
