EU external representation and the International Law Commission: an increasingly significant international role for the European Union?

With this working paper, CLEER aims to offer a better insight into selected legal aspects concerning the European Union’s redefined diplomatic persona. In particular, the working paper will address issues pertaining to the Lisbon Treaty’s organising principles of EU external action, both under EU law and international law, and the growing practice of external representation of the European Union, especially in the context of other international organisations and bodies. Many questions remain unanswered in this respect, for instance: how can we best understand the relationship between the way the EU decides upon international positions and organises its external representation on the one hand, and its influence, performance and/or effectiveness on the other hand? Does the European Union’s formal status as a subject of international law justify an upgraded observer status within international organisations, a seat additional to that of the EU Member States, or should the EU replace them? Does it matter who speaks for the EU, and in what way? How should we square the emergence of the European External Action Service (EEAS), a hybrid organ consisting of EU civil servants and seconded diplomats from the Member States, with the traditionally state-centred body of international diplomatic law? And what can be expected from the High Representative, the EEAS and its vast network of diplomatic representations in third countries and multilateral settings in the pursuit of the Treaty’s external objectives?
