Introduction

Part III.A of the evident partiality segment of this series discussed the parties’ reasonable expectations of neutrality.  Today we consider how those expectations are enforced. 

“Evident partiality” challenges typically arise out of one of two scenarios.  First, there are “presumed bias” cases in which the arbitrator’s relationship to the parties or the controversy would lead a reasonable person to conclude that the arbitrator was biased, even though the challenger cannot prove actual bias.    Second, there are evident partiality challenges based on allegations of actual bias.  For example, suppose a neutral said on the record during the proceedings prior to deliberations:  ”Party A, frankly I have distrusted your company’s business motives for many years, but hearing your witnesses’ testimony has simply confirmed what I’ve suspected all along.”  While the chances of an arbitrator making such a statement (let alone on the record) are exceedingly slim to non-existent, it would provide the basis for an evident partiality challenge (which would probably succeed) based on proof of actual bias. 

The difference between “presumed” and “actual” bias is simply one of proof.  One is based on circumstantial evidence and the other on direct evidence.  Our focus will be on “presumed bias” cases, because they arise with greater frequency.  Actual bias is very difficult to prove, and if it or something approaching it can be established, then that proof would in any (or most any) event meet the standards necessary to establish evident partiality.    Continue Reading »
