Why use CEDR for ISDS Mediation?

Traditionally Investor-State disputes (ISDS) have been settled by Arbitration often through established International Arbitral bodies. CEDR is the only mediation-focused international ADR Body that has the experience of designing, setting up and managing complex international mediations,  with over 30 years’ experience of mediating international disputes with parties from over 70 countries involving commercial contracts subject to a range of national laws, and multiple types of business issue from acquisitions and energy to media and telecoms cases. 

ISDS is complex and raises issues that only an Institution with a mediation focus for over 30 years can assist in resolving. Our administrators are dedicated to assisting the parties and the mediators in establishing the platform for each case needed to resolve cases through to settlement. This includes assisting with:

  • Understanding the ISDS process
  • Understanding cross-culture dynamics
  • Stakeholder mapping
  • Press and communication protocols
  • Structuring co-mediations
  • Arranging hearing rooms and providing administrative and translation services
