An arbitral award may only be set aside under Article 34(2) of the Model Law in limited circumstances. The public policy ground under Article 34(2)(b)(ii) must be restrictively construed to preserve the basic objective of finality in arbitration. An award is not contrary to public policy merely because the arbitrator's reasoning or conclusions are wrong in fact or in law. An award will only be set aside on public policy grounds where the reasoning or conclusions violate some fundamental principle of law, morality or justice, or constitute a palpable inequity so far reaching and outrageous in its defiance of logic or accepted moral standards that a sensible and fair-minded person would consider that the conception of justice would be intolerably hurt by the award. Where parties refer a dispute to arbitration without formally specifying particular issues, the arbitrator has broad discretion to resolve all aspects of the dispute that fall within the general subject matter of the submission.
