Path-dependent institutions and strategic veto players: National parliaments in the European Union

According to the prevailing concept of 'dual legitimacy', national parliaments constitute an important source of democratic legitimacy in the EU. Reinforced parliamentary scrutiny and control of the national representatives in the Council of Ministers seem to contribute to a more democratic Europe. However, if parliaments tie the hands of their governments when they negotiate at the European level, effectiveness of policy-making is jeopardised and national interests may be defeated. Realising this dilemma, members of national parliaments develop strategies to deal with conflicting requirements of national party politics and European policy-making. These strategies and their implications for democracy are influenced by the path-dependent institutional changes in national parliamentary systems. They therefore vary considerably between member states.
