On 1 June, the new arbitration rules of the International Chamber of Commerce (ICC) entered into force, introducing significant changes to the practice of international dispute resolution. The new set of rules applies to all new cases submitted to the ICC International Court of Arbitration and is designed to enhance efficiency, transparency, and the speed of proceedings.

Why is this relevant for businesses and their legal counsel?

The ICC Rules continue to provide one of the most respected frameworks for international arbitration. The 2026 reform is particularly important for businesses engaged in complex contractual relationships across multiple jurisdictions, as the new rules offer modern, practice-oriented solutions for the swift and predictable resolution of disputes.

Key innovations

The new rules introduce several innovative features reflecting market demands:

• Expedited and “highly expedited” proceedings
  The so-called Highly Expedited Arbitration Provisions (HEAP) make it possible for parties to receive a final decision within as little as three months in certain less complex cases.
• More flexible commencement of proceedings
  The reduced emphasis on the mandatory use of the Terms of Reference increases procedural flexibility and lowers formalities.
• Strengthening arbitrator independence and transparency
  The rules on conflicts of interest and disclosure obligations applicable to arbitrators have been further tightened, increasing the parties’ confidence in the proceedings.
• Possibility of early determination
  The “early determination” mechanism makes it possible to resolve certain issues swiftly and on the merits at an early stage of the proceedings.
• Digitalisation and efficiency
  The modernisation of the rules on communications, deadlines, and the rendering of awards clearly serves the goal of faster and more cost-effective proceedings.

What does this mean in practice?

The new ICC Rules clearly point the international arbitration market toward faster, more structured, and more business-friendly dispute resolution models. This is particularly relevant for international contractual structures such as energy, infrastructure, or distribution projects, where prompt decision-making represents significant commercial value.
