Overview
On 22 May 2026, the International Chamber of Commerce (ICC) released its updated Arbitration Rules, effective for all arbitrations begun on or after 1 June 2026. The new rules introduce a range of procedural changes, targeted at increasing speed and efficiency in ICC-administered arbitration, while retaining party flexibility. Notable additions include a highly expedited arbitration procedure, a formal mechanism for early dismissal of claims, expanded emergency arbitrator provisions, broader default expedited procedures, and elimination of the mandatory Terms of Reference.
What Happened
The ICC announced its 2026 Arbitration Rules, which will govern all arbitrations filed from 1 June 2026 onward. According to ICC Arbitration Court President Claudia Salomon, the aim is to make arbitration more efficient without compromising procedural integrity.
Key amendments include a new 'Highly Expedited Arbitration Provisions' (HEAP), allowing parties to opt for a streamlined process with a final award within three months of the initial case management conference, always handled by a sole arbitrator. HEAP does not apply automatically, and parties must opt in.
The updated Rules also grant tribunals explicit power to summarily dismiss claims or defences that are manifestly without merit or outside tribunal jurisdiction. This aligns ICC practice with other leading arbitral institutions such as the SIAC, LCIA, and HKIAC.
The emergency arbitrator regime has been broadened, allowing applications against non-signatories under certain conditions. Preliminary orders can now be issued without notice to prevent misuse of urgent relief requests and ensure effectiveness, with procedural safeguards in place.
The scope of the default Expedited Procedure Provisions (EPP) rises to disputes below $4 million, reflecting trust in streamlined management of higher-value claims. In 2025, 40% of ICC-registered cases were below this value.
The requirement for Terms of Reference has been dropped as a mandatory step, although parties can still adopt such terms voluntarily. Further, administrative expenses and arbitrators' fees were reduced for cases under $10 million but increased above that level.
Context
The ICC's amendments respond to demand for quicker, less costly arbitration amid consistently high caseloads, with 1,869 ongoing cases at the end of 2025 and almost $300 billion in pending disputes. These reforms reflect procedural innovations adopted by other prominent institutions and feedback from global arbitration users.
The introduction of highly expedited and early dismissal measures follows industry trends led by SIAC and others, enhancing options for parties seeking swift dispute resolution. The move to make Terms of Reference optional simplifies proceedings and may accelerate initial steps in ICC arbitration.
Why It Matters
- The 2026 ICC Rules aim to maintain the leading position of ICC arbitration by making proceedings faster and more accessible for various dispute values.
- Broader expedited options, streamlined early dismissal, and adjusted fee structures could lower time and cost barriers, attracting more moderate-value disputes and reinforcing the ICC's global competitiveness.
