About the Event

The 9th Intersessional Meeting of UNCITRAL Working Group III on Procedural Rules and Cross-Cutting Issues will take place on 5–7 November 2025 in Santiago, Chile. The meeting will gather government representatives, practitioners, academics, and stakeholders to discuss key aspects of the ongoing reform of investor–State dispute settlement (ISDS).

The meeting will focus on draft provisions under consideration by the Working Group, with particular attention to procedural rules and cross-cutting issues that are central to the reform process. It will also provide an opportunity for dialogue, capacity-building, and the exchange of perspectives that will enrich the discussions taking place in Vienna and New York.

By creating an open and inclusive space for engagement, this intersessional meeting will contribute to advancing UNCITRAL’s work towards a more effective and balanced ISDS system.
