A court may correct an arbitration award if (a) there is an evident miscalculation or mistake of description, (b) the arbitrator exceeded his powers and the award can be corrected without affecting the merits of the decision, or (c) the award is imperfect in a matter of form not affecting the merits. Here, the arbitrator allowed a set off of one party’s recovery against the other’s recovery. A lender to one of the parties intervened in the court proceeding to confirm or correct the award to assert its prior security interest in one party’s claim against the other, which the offset undercut. This decision holds that the court did not have the power to correct the award to undo the offset because it would affect the merits of the decision–remedies as well as liability are part of the “merits” of the decision. The party that borrowed from the lender did not seek to vacate the award, and as correction was not possible, the award had to be confirmed. A strong dissent argues that the parties have no power to waive the rights of a non-arbitrating party.
