From Paris to Dublin: Domestic Politics and the Treaty of Lisbon

This article discusses the domestic politics of treaty reform in the European Union, from the failed referendum on the Constitutional Treaty held in France in May 2005 to the failed referendum on the Treaty of Lisbon held in Ireland in June 2008. A meticulous examination of the national level, it is argued here, helps us to better understand the European level and why some Member States manage to influence outcomes more than it would be expected. In particular, this article looks at the role played by actors beyond national governments, the impact of the political system and the general context on preference formation and inter-state bargaining, and the use that national negotiators made of ratification hurdles to receive extra concessions. More generally, by looking at the preparatory, negotiation and ratification process of the Treaty of Lisbon, this article aims to make a contribution to an emerging literature, which argues that we can no longer explain the evolution of the European Union without understanding the increased politicisation of the European project.
