This article contributes to the debate on non-signatories by relying on the Kluwer Research project. In particular, through the raw data underlying the Kluwer Research, we have identified cases at the enforcement stage, in which courts had to decide whether, despite the apparent lack of consent, nonsignatories were correctly brought into arbitration proceedings. In our view, the analysis of those courts’ decisions is perhaps a reminder that when considering non-signatory issues, the relevant facts of the case are always what matters the most. Non-signatories’ involvement in the relationship underlying the dispute is essential, absent a clear expression of it in the contract.We believe that the results show the judicial solution to the arbitrator’s dilemma, that is, the due consideration of the circumstances of any case, disregarding the rigid application of any theories.
