Under CPLR 7511, a party may move to vacate or modify an award if it demonstrates by clear and convincing proof that its rights were prejudiced by the arbitrator's partiality. Partiality can be established by proof of actual bias or the appearance of bias from which a conflict of interest may be inferred.
