The European Union and the Law of Treaties: A Fruitful Relationship

Abstract

Abstract This article examines the European Union’s (EU) treaty practice from the perspective of the international law of treaties, focusing on its most significant examples. The starting point is the EU’s attitude towards the codification of treaty law involving states and international organizations. The article discusses certain terminological specificities and a few remarkable aspects, such as the frequent use of provisional application mechanisms as opposed to much less use of reservations, the contributions regarding treaty interpretation, the wide variety of clauses and the difficulties in determining the legal nature of certain texts. The study underlines that treaty law is a useful instrument for the Union and is further enriched with creative contributions; the outcome is a fruitful relationship.
