As several prior posts on this blog have discussed (see here, here, and here), corruption has emerged as a significant and controversial issue in international investor-state arbitration proceedings, with a number high-profile cases in which the tribunal refuses to provide relief on the grounds that the underlying contract was procured through corruption. In these cases, corruption allegations usually surface at the initiative of one of the parties. For example, this summer, Djibouti filed an arbitration against Dubai-owned port operator DP World, seeking annulment of a port concession because DP World allegedly formed its contract with Djibouti for the operation of Africa’s largest container terminal through corrupt means. However, in rare instances, corruption can enter the picture without either party raising the issue during the proceedings. In these cases, the arbitral tribunal considers the issue of corruption sua sponte, even when neither party alleges corruption by the other.

Perhaps the most prominent example of this is the tribunal’s decision in Metal-Tech v. Uzbekistan. In Metal-Tech, the ICSID tribunal, in its words, “required explanations” from the parties for suspicious facts that “emerged in the course of the arbitration”–in particular the fact that Metal-Tech had paid exorbitant, seemingly unjustifiable sums for consulting services to an Uzbeki government official and individuals with close ties to Uzbeki leadership. The ICSID tribunal then essentially placed the burden of disproving corruption in light of this circumstantial evidence on Metal-Tech, which could not come up with enough evidence to overcome the tribunal’s presumption. The ICSID tribunal held it did not have jurisdiction and dismissed Metal-Tech’s claim.

On the surface, sua sponte efforts by tribunals to address corruption may seem like a positive step in the anticorruption fight. Indeed, it might seem irresponsible for the tribunal to stick its head in the sand given such facially suspicious facts. As Michael Hwang and Kevin Lim assert in a recent paper endorsing this sua sponte practice, “Tribunals must remain vigilant and alert to the possibility of corrupt dealings being hidden by one or both parties, otherwise they may become unwitting accessories to heinous acts.” But in fact, the approach adopted by the tribunal in Metal-Tech, might do more harm than good. Indeed, by engaging in sua sponte considerations of corruption, arbitral tribunals might unwittingly perpetuate corruption under several different scenarios: Continue reading →
