The International Chamber of Commerce International Court of Arbitration (ICC), established in 1923, has released an update to its rules which will apply to arbitrations which begin on or after 1 June 2026 unless otherwise agreed by the parties (2026 ICC Rules). The new rules build on previous iterations developed over the past century while incorporating several new innovations – including a process for having a claim or defence dealt with summarily at an early stage; a new three-month highly expedited procedure; and a mechanism for a party to seek emergency relief without alerting the other side.
