International arbitration cannot withstand the inexorable march of technological progress any more than the national courts with which it competes for jurisdiction. As recently as this month, Clifford Chance – a leading law firm – announced a comprehensive training programme for its lawyers that covers cybersecurity, block chain technology and predictive coding. In this article, I will argue that predictive coding can, and should, bring efficiency gains and costs savings to the document production phase, and thus the arbitration process overall. given the flexibility already inherent within the arbitral process, predictive coding can, and should, fit into proceedings without any need for changes to arbitration laws or institutional rules. In all likelihood, it is already doing so. examples of quick adoption in other jurisdictions indicate that predictive coding is likely to become commonplace sooner than many practitioners expect.
