FIRST DISCUSSIONS ON DAMAGES IN THE INVESTOR-STATE DISPUTE SETTLEMENT SYSTEM AT UNCITRAL WORKING GROUP III

By José Manuel Alvarez Zárate

This paper summarises the history of initial discussions within UNCITRAL Working Group III (WG.III) on the reform of investor-state dispute settlement (ISDS) regarding the lack of correctness, consistency and predictability of compensation awards. It covers the period up to 2022, beginning with the initial concerns expressed by some countries of the Global South regarding the methodologies used to assess damages and the Draft on Damage Assessment and Compensation prepared by the UNCITRAL Secretariat, which served as the basis for subsequent discussions among the members of WG.III. It then describes the comments made by some states and observers on this draft and the discussions that ensued, including the discussion of damages as part of the issues of ISDS reform. A second paper on this topic will describe the period from September 2022 to the publication by the Secretariat of the second draft of procedural and cross-cutting issues on July 8, 2024.

The purpose of this paper is to provide Global South States with a track record of the main concerns expressed by States on various aspects of damages during the discussions in UNCITRAL WG.III, which have often been lost at some point during the long process of discussions on ISDS reform.
