Effective June 1, 2026, the new ICC Arbitration Rules are now in force. Here are the 4 key changes that matter most to practitioners:
1. Removal of Mandatory ToR #
The Terms of Reference is no longer mandatory for all cases. Arbitral tribunals now have discretion to decide whether a ToR is necessary. This reduces unnecessary procedural delays and costs.
2. Expedited Procedure threshold raised to $4M #
More cases can now benefit from the streamlined expedited procedure. Plus, a brand-new HEAP (Highly Expedited Arbitration Procedure) has been introduced——awards within 3 months for eligible cases!
3. Digitalization formalized #
No hard copy, no heavy luggage dragging! Electronic communications are now the default. E-signatures EXPLICITLY authorized. Tribunal may sign electronically after consulting parties. Cross-border arbitration just got a lot more efficient.
4. Enhanced transparency & emergency relief #
Arbitrator disclosure obligations strengthened (“when in doubt, disclose”). Emergency arbitrators can now issue ex parte preliminary orders and target third parties in exceptional circumstances.
