The European Union has a unique sui generis status on the international plane, which is reflected in its capability to enter into diplomatic relations with third states and international organizations. Over nearly six decades, the European Union (EU) has gradually built its own worldwide bilateral and multilateral diplomatic network, which is made subject — through specific agreements with the host country — to the 1961 Vienna Convention on Diplomatic Relations. The ‘Union delegations’ are now operating as the diplomatic missions of the EU as a whole, in contrast to the former Commission delegations. This article examines the relationship between the EU and international diplomatic law. How does the EU establish and conduct diplomatic relations? What legal instruments are being used? How do the Vienna Convention and customary diplomatic law come into play? What is the exact legal status of EU ambassadors and diplomatic staff? By critically analysing these issues, this article assesses the specific contribution the EU makes to the further development of international diplomatic law.
This contribution briefly discusses the methodological and conceptual issues faced by the ILC during its work on the responsibility of international organizations. It examines some of the key challenges faced by the ILC, including the lack of relevant international practice, and the diversity of international organizations. It argues that while the responsibility of international organizations remains an important topic for international law, the law is not yet developed enough for codification of secondary rules to apply to all international organizations. In some cases, this led the ILC to rely heavily on its Articles of States Responsibility. This approach pushed the work of the ILC closer to ‘progressive development’ of the law than to codification.
As the title suggests, in this contribution we will devote some reflections to a number of challenges we see for the law of international organizations, and more specifically for the teaching of this discipline. This exercise is part of the introduction of a masters' course on the law of international organizations in the framework of the Bachelor-Master (more popularly: "Bama") reforms at Leuven University. As such, it reflects our personal point of view, but we hope it may be useful for our colleagues – likewise, we would be very grateful for any constructive comments as this is an ongoing process.First, we will address the teaching method, second, the link between research and teaching and third, the study material. We will conclude by briefly outlining our approach to teaching in this field of law, as one possible way this teaching can be done.
