Civil Society in Investment Treaty Arbitration: Status and prospects

By Farouk El-Hosseny, Published by Brill | Nijhoff, January 2018

This book provides an overview of the evolution of civil society’s participation as amicus curiae before investment tribunals, an evolution that fits within a broader movement towards transparency in investment treaty arbitration. By looking at the procedural roles available to civil society before other jurisdictions, the author questions whether the amicus role could be expanded. El-Hosseny ultimately shows that the issue of civil society’s participation in investment treaty arbitration transcends the procedural realm: it is equally about arbitral tribunals’ openness vis-à-vis public interest, environmental protection and human rights issues.
