On May 22, 2026, the International Chamber of Commerce (“ICC”) released its new arbitration rules (the “2026 Rules”), which place greater emphasis on early case management and procedural structuring, increase the availability of expedited procedures, and codify new mechanisms to narrow or resolve disputes at an early stage. In practice, parties may need to define the scope of the case and crystallize key arguments at the outset, while also benefiting from expanded opportunities to reduce time and cost where appropriate. Key changes eliminate burdensome procedural tools, expand expedited procedures, introduce a new highly expedited track, and codify a mechanism for early dismissal of unmeritorious claims. The ICC’s recent rule changes reflect its commitment to providing users across jurisdictions with a range of tools for the efficient and expeditious resolution of disputes.
Background
The ICC provides a leading forum for resolving cross‑border commercial disputes, used across industries such as construction, energy, finance, and technology. The ICC periodically updates its rules to reflect evolving arbitration practice. The 2026 Rules replace the prior version that took effect on January 1, 2021 and will apply to arbitrations commenced on or after June 1, 2026, unless the parties’ contract provides otherwise; cases already underway will continue under the 2021 Rules.[i]
Streamlining Early Case Management
The 2026 Rules elevate the Case Management Conference as the central step for organizing a case. This early procedural meeting—typically the first substantive interaction among the tribunal and the parties—serves as the forum for setting the course of the arbitration, including the scope of the dispute and the procedural framework. This conference is mandatory and must now take place within 30 days of the tribunal receiving the initial file. This shift is driven in part by the removal of mandatory Terms of Reference—a document historically prepared early in the case that summarized the parties’ claims and defenses and defined the scope of the arbitration—which added time and cost, particularly in complex or multi‑party arbitrations.[ii]
Expanding the Tools to Accelerate Arbitration
The 2026 Rules expand the tools available to tribunals to accelerate proceedings, including broader use of expedited processes and new mechanisms to resolve issues earlier in the case.
Emergency Arbitration. Emergency arbitration allows a party to obtain urgent interim relief before the tribunal is constituted. Under the 2026 Rules, relief may now be sought against any party the President of the ICC Court believes may be bound by the arbitration agreement, not just original signatories and their successors. The Rules also introduce “preliminary orders,” which the emergency arbitrator may issue without notifying the other side where advance notice would defeat the relief’s purpose, subject to procedural safeguards.[iii]
Expedited Procedure. The Expedited Procedure provides a streamlined arbitration: a single arbitrator, compressed timetable, fewer submissions, limited document production and no full evidentiary hearing (where appropriate). The 2026 Rules raise the automatic threshold for expedited procedures from US$3 million to US$4 million, bringing more mid-sized disputes within this track by default unless the parties agree otherwise.
Highly Expedited Arbitration. A new opt-in track is designed to deliver a final decision within three months of the initial Case Management Conference, regardless of the amount in dispute. Cases may be decided by a single arbitrator on a documents-only basis; parties must present their full case at the outset; and the parties may agree to dispense with a reasoned award.[iv]
Early Determination of Claims or Defenses That Are Manifestly Without Merit. The 2026 Rules allow arbitrators to dispose of claims or defenses that are manifestly without merit or fall outside the tribunal’s authority. While previous ICC guidance indicated that the tribunal had discretion to determine whether to allow an application by a party for expeditious determination of manifestly unmeritorious claims to proceed, the 2026 Rules formalize and codify the tribunal’s authority.[v] The threshold for early dismissal remains high, and its application is expected to develop through arbitral practice.
Time Limit for the Final Award. The prior six-month default deadline, measured from finalization of the Terms of Reference, no longer applies. The President of the ICC Court will set—and, where appropriate, extend—the time limit for the final award based on the circumstances of the case or a reasoned request from the tribunal.[vi] Simpler disputes may move faster, while complex or multi-party cases can be given the time they reasonably require.
Enhancing the Early Detection of Conflicts of Interest
A core feature of arbitration is that the decision‑maker must be neutral.[vii] Arbitrators must therefore disclose any relationships or circumstances that could raise questions—real or perceived—about their independence. The 2026 Rules add two practical clarifications to the existing disclosure framework: where in doubt, arbitrators are expected to err on the side of disclosure; and disclosure does not, by itself, suggest bias. Parties also face new obligations at the outset: they must identify individuals or entities relevant for conflict checks and explain why.[viii] Taken together, these changes are intended to surface potential conflicts earlier and reduce the risk of later challenges to the tribunal.
Other Notable Changes
The 2026 Rules also include a number of practical changes. First, if one arbitrator is unable to continue late in a case—including after the final hearing—the remaining arbitrators may be permitted to complete the arbitration, helping avoid delay and additional cost. Second, the Rules clarify the role of tribunal secretaries (the assistants who support the arbitrators), requiring them to meet the same independence standards as arbitrators and confirming that their compensation cannot be arranged directly with the parties. Third, written communications will now be conducted electronically by default, with paper copies required only in limited circumstances, and awards may be signed and delivered electronically—reflecting a broader shift toward digital processes, while future guidance on emerging technologies is expected to be developed outside the Rules framework. Fourth, detailed “case management techniques” have been moved out of the Rules and into separate guidance, allowing those best practices to be updated more easily over time. Fifth, ICC administrative fees have been reduced for disputes under US$10 million, which should make smaller cases more cost‑effective, while modest increases apply to larger disputes. Finally, the ICC Secretariat will now handle routine financial matters, such as setting advances on costs, while the ICC Court continues to oversee arbitrators’ fees and overall charges.[ix]
