The two FAA grounds for vacating an award not found in the Model law are: (a) the award was procured by corruption, fraud, or undue means; (b) there was evident partiality or corruption in the arbitrators. Additionally, an award subject to the FAA can be set side on the ground of ‘manifest disregard of law’ which was added by the US Supreme Court in Wilko v Swan. Although the manifest disregard of the law standard has been applied extremely sparingly by the US courts, it has been used to vacate a number of domestic arbitral awards rendered in the US. Several courts have indicated that the standard is, in theory, applicable to international arbitration awards rendered in the US although it has not yet been applied to vacate an international award.
