I. INTRODUCTION
International investment arbitration has become the “fastest growing area of international law”1 and is now the preferred option for the settlement of investment disputes.2 This increased use of international investment arbitration has also translated in more challenges of appointed arbitrators.3
Several reasons explain why challenges of arbitrators are now more common. In part, this is caused by the repeated use of a limited number of arbitrators to resolve similar international disputes, which increases the potential for real or perceived conflicts of interest, whether personal, professional, or case – or issue – related. Additionally, in certain instances, challenges are frivolous, and are merely used to delay and protract proceedings.
