Artificial intelligence (“AI”) is increasingly being used in international arbitration for legal research, document review, translation, and drafting. However, its use becomes difficult to assess when an arbitrator turns to AI not merely to process information, but to obtain a view on a legal issue that the tribunal must decide.
There is presently no generally applicable rule across international arbitration prohibiting an arbitrator from putting legal questions to AI. Indeed, in February 2026, UNCITRAL devoted part of a colloquium specifically to “Arbitrators and the Use of AI – Impact on Recognition and Enforcement”, reflecting the fact that the issue remains under consideration internationally.1
