ICC Arbitration Rules

Revision 2026 – Greater Efficiency, Greater Flexibility

The revised ICC Arbitration Rules 2026 entered into force on 1 June 2026. The amendments build on the well established framework of the previous Rules, with a strong focus on improving procedural efficiency, increasing flexibility and providing greater clarity for parties and arbitral tribunals.

Key changes include:

Terms of Reference no longer mandatory: The previously required document defining the framework of the proceedings is now optional. Instead, greater emphasis is placed on a structured early Case Management Conference, helping to reduce both time and costs.
Expedited proceedings: The threshold for the automatic application of the Expedited Procedure has been increased to USD 4 million. In addition, new Highly Expedited Arbitration Provisions have been introduced for cases requiring an even faster resolution.
Early determination of manifestly unmeritorious claims: Arbitral tribunals may decide claims or defences that are manifestly without merit or inadmissible at an early stage of the proceedings.
Further modernisation: The Rules strengthen digital case management, clarify confidentiality and disclosure obligations, and enhance transparency in the organisation of arbitral proceedings.With the ICC Arbitration Rules 2026, the ICC responds to the evolving needs of modern international dispute resolution. The objective is to make arbitration proceedings faster, more streamlined and more cost effective, while maintaining the high standards of due process and legal certainty.
