Court Faults Party for Failing to Preserve Challenge to Arbitrator

The U.S. District Court for the District of Vermont denied a motion to vacate an arbitration award after it concluded that the party seeking vacatur had failed to identify information it claimed made the arbitrator evidently partial and then failed to ask the arbitrator to recuse himself once that information came to light.

ICI Mutual Insurance Co. (ICIM) and reinsurers Hamilton Managing Agency Ltd. and Antares Managing Agency Ltd. arbitrated a reinsurance matter. The arbitrator ruled in favor of ICIM. ICIM moved to confirm the award and the reinsurers moved to vacate it. The reinsurers argued, among other things, that the arbitrator had failed to timely disclose relevant testimony he had previously given and that the award should be overturned for evident partiality as a result.

The District of Vermont rejected the reinsurers’ claim. It noted that the reinsurers could have discovered the arbitrator’s testimony through basic searches before selecting the arbitrator or by asking for the arbitrator’s CV. The reinsurers apparently failed to conduct those searches or even ask for the arbitrator’s CV. They instead agreed to the arbitrator. The reinsurers then learned about the arbitrator’s prior testimony during the arbitration but did not formally request that the arbitrator withdraw or seek recusal. They instead informally asked the arbitrator to consider whether his prior opinions would inhibit his ability to decide the issues fairly. The district court explained that the reinsurers had waived any challenge to the arbitrator by failing to investigate the arbitrator’s testimony and not formally asking the arbitrator to recuse himself. The district court also held that the reinsurers had not established that the arbitrator was evidently partial in any event. The court also rejected the reinsurers’ arguments that the arbitrator had exceeded the scope of his authority and manifestly disregarded the law.
