ICSID Convention Arbitration Rules

​​​​The Arbitration Rules apply to proceedings under the ICSID Convention after registration of the request for arbitration. They address:

  • establishment of the Tribunal (Chapter I);
  • working of the Tribunal (Chapter II);
  • general procedural provisions (Chapter III);
  • written and oral procedures (Chapter IV);
  • particular procedures (Chapter V), such as provisional measures, preliminary objections, and discontinuance;
  • the Award (Chapter VI);
  • the post-award remedies of Interpretation, Revision, and Annulment of the Award (Chapter VII); and
  • final provisions (Chapter VIII).
Article 44 of the ICSID Convention provides that arbitrations will be conducted in accordance with the Arbitration Rules in effect on the date on which the parties consented to arbitration, except as the parties otherwise agree.
The Arbitration Rules were adopted on September 25, 1967 and were effective as of January 1, 1968. These were published with non-binding explanatory notes: ICSID Arbitration Rules (1968).
The Arbitration Rules have subsequently been amended three times. The first amendment was approved and took immediate effect on September 26, 1984: ICSID Arbitration Rules (1984). The second amendment was approved on September 29, 2002 and was effective on January 1, 2003: ICSID Arbitration Rules (2003).
The current rules were approved by written vote of the Administrative Council in 2006 and came into effect on April 10, 2006. These rules were adopted after a 2-year period of public consultation.  This consultation included a discussion paper released on October 22, 2004 on Possible Improvements of the Framework for ICSID Arbitration and a working paper released on May 12, 2005 on Suggested Changes to the ICSID Rules and Regulations.
