In November and December 2013, tribunals constituted under the Rules of the International Centre for Settlement of Investment Disputes (“ICSID”) considered three proposals for arbitrator disqualification stemming from investment disputes in Latin America, and ultimately disqualified two arbitrators in pending proceedings. While the ICSID procedural rules envision challenges to arbitrators, arbitrator disqualification is traditionally an extremely rare result in ICSID proceedings. Accordingly, it is worth analyzing whether the recent rise in successful challenges to ICSID arbitrators marks the beginning of a new adjudicatory trend, and what such a trend may mean for ICSID arbitration.
