What has the Investor-State Taskforce achieved so far?

IMI’s Investor-State Mediation Taskforce has assisted the development of Investor-State mediation competency standards, a model instrument for States implementing an Investor-State conflict management framework and revised mediation rules and guides for Investor-State dispute resolution provider organisations. IMI has also teamed with other Investor-State organisations to launch a series of Investor-State mediator skills training programmes.


  1. Offer practical guidelines for using the cooling off period to give mediation a viable chance
  2. Determine minimum standards of knowledge, skills and relevant experience for neutrals involved in Investor-State mediation
  3. Assist the parties in finding competent and suitable mediators or co-mediators for Investor-State disputes.
  4. Ensure a Designating Authority is identified if the parties cannot agree on one
  5. Provide model documents, decision trees, and case assessment tools to assist the parties and their counsel in Investor-State disputes to gain fresh insights into their case, and better understand each party’s interests, needs and concerns
  6. Keep the Mediation Rules quite distinct from Conciliation Rules
  7. Enable the creative use of hybrids, such as Dispute Resolution Boards
