Since it was adopted in 1969, the Vienna Convention on the Law of Treaties (VCLT) has come to be widely regarded as one of the International Law Commission’s (ILC’s) greatest successes. Indeed, the VCLT’s drafting history reflects that the ILC sought to create an enduring set of provisions constituting a law of treaties – regardless of the specific features of the individual treaties to which such rules might come to be applied. This enduring legacy is quite notably reflected in the VCLT's role in modern international investment law and investor-State dispute settlement (ISDS). In the decades since it entered into force, the VCLT has profoundly influenced investor-State disputes. In the coming decades, such disputes are only likely to become more relevant to understanding the VCLT’s rules. The VCLT will, in turn, impact and shape investment law and arbitration opportunities in the future. The relationship between the ILC’s work, the VCLT, and international investment law and ISDS is developed in the recently published book, The Vienna Convention on the Law of Treaties in Investor-State Disputes: History, Evolution, and Future edited by Esmé Shirlow & GW Law Professor Kiran Nasir Gore (Kluwer, 2022). While the VCLT alone does not provide solutions to all the challenges currently faced by international investment law and ISDS, nor all of the challenges likely to emerge in the future for this body of law, the ILC’s vision and the VCLT’s tools certainly have a key role to play.

This “in conversation” webinar will engage present and past members of the ILC in an interactive format to examine these themes. Moderated by Lucy Reed, the event will feature Professor Sean D. Murphy, ILC Member 2012-2022, Dr. Vilawan Mangklatanakul, ILC Member 2023-2027, Professor Martins Paparinskis, ILC Member 2023-2027, and Dr. Penelope Ridings, ILC Member 2023-2027. The program will highlight the role of the ILC and VCLT in understanding the development and future of international investment law and ISDS and will be relevant to adjudicators, practitioners, government officials, and scholars interested in the future of this field of law and public international law more broadly.


Open to everyone.
