Abstract

The United Nations International Law Commission occasionally deals with the law relating to international organizations. A well-known example is its work in preparation of the Vienna Convention on the Law of Treaties between States and International Organizations or between International Organizations of 1986. It is less well-known, but perhaps more important for the practice of international organizations, that the Commission has in recent years also addressed other relevant issues in this field. Those include the responsibility of international organizations (2011), the role which the practice of international organizations may play in the interpretation of their constituent instruments (2018) and in the formation of customary international law (2018), as well as considerations on whether the topic ‘Settlement of disputes to which international organizations are parties’ (2016) should be put on its agenda. This chapter reflects the 2018 aiib Law Lecture, summarizing the work of the Commission on these aspects of the law of international organizations and engages in some general reflections.

Treaties and their Practice

Symptoms of Their Rise or Decline

Georg Nolte

The book describes the development of certain important treaties from the perspective of their practice, with a view to assessing whether these treaties are, or have been, on the “rise” or in “decline”. Following a glance at major European peace treaties prior to the UN Charter, the book focuses on developments over the last thirty years with respect to the UN Charter and its rules on the use of force, human rights treaties, the WTO agreements, investment treaties, and environmental treaties. It looks at these treaties from the perspective of an observer as well as from the perspective of a practitioner who is called to apply a treaty, taking into account the rules of interpretation under the Vienna Convention on the Law of Treaties. The book describes, in particular, how the International Law Commission has elucidated the significance of the rules of interpretation in its conclusions on “Subsequent agreements and subsequent practice in relation to the interpretation of treaties” (2018), and it connects this work with the broader developments.
