The Lisbon Treaty fundamentally changed the presidency regime of the European Union at the expense of one of the oldest and most central institutions of European integration: the rotating presidency. The chair positions of the European Council, the Foreign Affairs Council and the Eurogroup have been decoupled from the rotating presidency. Understanding the reduced role of the rotating presidency requires attention for the changing dynamics of EU policymaking, especially for the new intergovernmentalism which implies decision-making outside the classic community method and for the rise of the European Council to the status of a lead institution.
