Working Paper no. 2 (2026) - Celine Lange, Alexandre Senegacnik, “A Call for Proactive Approaches in ISDS Arbitral Practice and Procedure - Engaging with local communities in environment-related disputes”. This Paper examines how a more proactive procedural engagement of arbitral tribunals with local communities' interests could contribute to ensuring that relevant public interest concerns are meaningfully considered in ISDS cases. The Paper seeks to demonstrate that, contrary to prevailing assumptions, arbitral tribunals are empowered, under existing procedural frameworks and through the exercise of their procedural discretion, to take on a more proactive role.
