Subject(s):

EU Treaty — Treaties, effect for third states

This chapter examines the EU’s robust and complex treaty-making. The first section deals with the EU’s treaty-making capacity from the perspective of EU law, and then of international treaty practice. It examines the ways in which international treaty-making practice has accommodated EU participation in bilateral and in multilateral agreements. The second section discusses the legal effects of treaties concluded by the EU, first as regards the EU legal order, including their enforcement and interpretation by the Court of Justice of the European Union and the legal effects of mixed agreements. A discussion of the impact of EU treaty-making on the powers of the Member States follows: through the doctrines of exclusivity and pre-emption, the impact of EU law on treaties concluded by the Member States, and finally EU treaty-making from the perspective of international responsibility.
