The International Chamber of Commerce has updated its Arbitration Rules, effective June 1, to improve procedural efficiency and transparency in resolving international commercial disputes. The new rules, known as the ICC Arbitration Rules 2026, aim to enhance case management and facilitate expeditious resolution of disputes.
The revisions reflect the ICC’s continued effort to modernize arbitral procedure while preserving flexibility and party autonomy. One significant reform is the abolition of the mandatory terms of reference, which previously defined the scope of arbitration before substantive proceedings could advance.
The revised framework places the initial case management conference at the core of procedural administration, requiring it to be convened within 30 days of the tribunal receiving the case file. New claims are barred after the initial conference unless the tribunal permits otherwise, considering factors such as the stage of proceedings and cost implications.

They also authorize tribunals to convene multiple conferences throughout the proceedings, enabling continuous case management and more proactive supervision of the arbitration. A notable innovation is the introduction of early determination, allowing parties to seek disposal of claims or defenses that are manifestly without merit or outside the tribunal’s jurisdiction.
The 2026 rules introduce Highly Expedited Arbitration, which operates with the consent of all parties and requires front-loaded pleadings, adjudication by a sole arbitrator, and delivery of the final award within three months of the initial conference.
The rules also strengthen interim relief by authorizing emergency arbitrators to issue ex parte preliminary orders where appropriate. The scope of emergency proceedings expands to encompass certain non-signatories in appropriate circumstances, and parties are now required to identify persons and entities relevant to arbitrator disclosures.
It is likely that the amendments will be welcomed by commercial parties and arbitral institutions, but they may also raise concerns about reduced early crystallization of issues and greater variations in procedural practice. The availability of ex parte preliminary orders may invite closer scrutiny from parties concerned with procedural fairness.

The updated rules constitute a carefully calibrated procedural modernization, prioritizing efficiency, transparency, and case management. The ICC’s primary goal seems to be balancing efficiency with the need for procedural fairness and party autonomy. As it continues to evolve its arbitral framework, it remains to be seen how these reforms will impact the resolution of international commercial disputes.
The International Chamber of Commerce has long been a leading institution in international arbitration, and these reforms aim to further solidify its position.
