Pick up any textbook or treatise on arbitration law, and you’ll find the same thing in the chapter on enforcing arbitral awards: courts cannot conduct a merits review of awards. Courts, in other words, do not second guess the conclusions of the arbitrators about law or facts.
Or at least they’re not supposed to do so.
Still, losing parties often try to convince a reviewing court that the arbitrator “exceeded her powers.” These sorts of excess of authority arguments have become quite common.
