This piece considers the interplay between arbitration and artificial intelligence (AI). It includes a general overview of the applicability of AI to arbitration proceedings. It questions the development from arbitration to ‘robotration’ and from human arbitrator to robot arbitrator. The author defines AI and focusses on the opportunities of its application in legal practice and in arbitration in particular. He acknowledges that Al does play an important and justified role in arbitration. It is impossible to imagine legal practice without legaltech nowadays and it will undoubtedly become increasingly sophisticated and helpful in the future; we all should be eager to participate in this process. However, by its nature, AI cannot decide law cases properly, as is argued by the author in a step-by-step analysis of the legal decision-making process in detail. This also applies to socalled ‘simple cases’. The author warns that cases can rarely be qualified in advance as being ‘simple’. Even dealing with default cases, for example, can be a delicate and complex matter: many technical legal issues may arise, especially in an international setting, and these require particular attention from a judge or arbitrator, sometimes even sua sponte. The detailed step-bystep analysis of the legal decision-making process in this article underlines that a judge or arbitrator never should be replaced by a robot, not even in simple cases.
