The ICC’s 2026 Arbitration Rules: An Early Preview Of The Changes (Part 2)

The International Court of Arbitration of the International Chamber of Commerce (ICC) has announced its revised 2026 ICC Arbitration Rules (the Rules), which entered into force on June 1, 2026. Per the ICC, the amendments are aimed at enhancing transparency and efficiency in ICC proceedings, strengthening confidence in the arbitral process, and codifying several practices that have already developed under existing ICC case administration.

The ICC published a series of preview articles highlighting key amendments and additions to the Rules in the lead up to their launch, and the Rules have now been published in their entirety. Part 1 of our Advisory summarized the first set of early insights from the ICC and highlighted the implications for ICC arbitration practice. This article, Part 2, reviews the other significant changes made in the Rules and the practical effects these changes may have for parties, counsel, and arbitrators engaged in disputes at the ICC.
