The Entry into Force of the Lisbon Treaty: The European Union in Retrospect and Prospect

Abstract

SummaryThe history of European integration unmistakably shows that it has progressed step by step and is indeed an ongoing and irreversible process. One such step is the conclusion of the Lisbon Treaty, which came into force on 1 December 2009, following negotiations spanning nearly a decade. The treaty aims, inter alia, at improving the functioning of the European Union (EU) and significantly amends the treaty basis of the EU as a supranational organization. It formally establishes the EU as a legal entity under public international law, strengthens the role of the European Parliament, and significantly reforms the role of the high representative of the union for foreign affairs and security policy. Moreover, the treaty has made the EU Charter on Fundamental Rights a legally binding and enforceable instrument and has expanded the competences of the EU in the fields of trade and other external commercial relations by providing it with exclusive competence to conduct the EU’s Common Commercial Policy. The author reviews these and other innovations of the Lisbon Treaty and briefly evaluates the treaty and its implications for the EU.
