General Context

The Conference and book analyze and discuss the connection between customary international law (CIL) and International Investment Law. While custom is a familiar companion to international investment law and arbitration, including treaty interpretation, state responsibility or the minimum standard of treatment, among many others, several areas and topics that highlight and investigate this inter-connection remain woefully under-analyzed and consistently overlooked. The present Conference and book aim at addressing this lacuna. It asks the question: how are custom’s relevant rules and principles being interpreted and applied by investor-state arbitral tribunals and how should they be interpreted and applied? The particular challenge lies, of course, in the object of interpretation: custom does not feature a written text. Hence, the interpretation of the unwritten word of custom, first, requires conceptual distinction from its identification and then, second, begs the questions how such interpretation of customary rules is conducted. This is further exacerbated in international investment arbitration, by the myriad of ad hoc investor-state arbitral tribunals whose approach to very same subject matter at issue may vary significantly. The contributions in the book and the Conference panels explore these and other related questions with a focus on custom identification, the interpretation of secondary rules and current challenges, such as the Covid-19 pandemic, natural resources and the precautionary principle.

No registration fee will be charged for the Conference. The program and registration link will be published soon.
