The Organizing Committee of the Conference “Custom and International Investment Law” is pleased to invite to the Conference, which will hold six thematic panels, an expert roundtable and feature several keynote speakers (with invited experts and speakers, inter alia former judge of International Court of Justice and arbitrators). Scholars and practitioners interested in presenting during the Conference are encouraged to send their proposals.

Organizers: Universidad Externado de Colombia; TRICI-Law (University of Groningen);Universität Tübingen; American University Washington College of Law.

The Conference’s subject is “Custom and International Investment Law”. The connection between customary international law (CIL) and International Investment Law has never been more pronounced. Despite this, several areas and topics that highlight this inter-connection remain woefully under-analyzed and consistently overlooked. The present Conference aims at addressing this lacuna. Therefore, we invite submissions of proposals engaging with any aspect that falls under the purview of these thematic issues:

  • Thematic Issue One: Importance and Evolution of CIL in International Investment Law
  • Thematic Issue Two: Interpretation of CIL in International Investment Law
  • Thematic Issue Three: State Responsibility and Wrongfulness in International Investment Law
  • Thematic Issue Four: State Responsibility and Compensation
  • Thematic Issue Five: CIL and Execution and Annulment Proceedings Before Domestic Courts
  • Thematic Issue Six: TWAIL,CIL and International Investment Law

More information on the thematic issues can be found here.
