Plaintiff-Appellant Melissa Smith appeals a district court order vacating a modification of an arbitration award. Defendant-Appellee Transport Workers Union
I.
Smith, former president of the Union, initially sued the Union about matters no longer pertinent in this appeal. The issue presently before us arose after the parties agreed to stay litigation and submit to binding arbitration, and indeed after an initial arbitral award in favor of Smith. Questions about taxation of additional costs and the arbitration panel’s authority to modify its initial award gave rise to this controversy. The arbitral panel determined that it had such authority and modified the award to tax additional costs against the Union, favoring Smith.
In district court Smith moved to confirm the modified award and the Union opposed confirmation of the award as modified, but not the original award. The district court agreed with the Union and vacated the modified award, confirming only the original award. 1
Our review of the district court’s confirmation or vacatur of an arbitrator’s award is de novo; our review of the arbitrator’s award itself, however, is very deferential. 2
Whether a contract requires arbitration of a given dispute is a matter of contract interpretation and a question of law for the court. 3 The arbitration agreement states that, “The arbitrators sua sponte may amend or correct their award within three business days after the award, but the parties shall not have a right to seek correction of the award.” 4
More than a month after the initial award, the arbitration panel found a modification to be “consistent with the arbitration agreement of the parties and the intention of the drafter of the award.” 5 Smith argues that the district court should accept the arbitration panel’s interpretation because it was based on evidence that was not before the district court. She contends that, without a transcript of the arbitration proceedings, we must presume the evidence was adequate to support the award. While Smith asks us to defer to the panel, we view the real question as a matter of contract interpretation and one for the courts, since it involves the question of the arbitrators’ authority. 6
Arbitration is a matter of contract; a party cannot be required to submit to arbitration unless it agreed in advance that the dispute would be arbitrated.
The plain wording of the arbitration agreement contemplates that the arbitrators will not consider correcting the arbitral award at all at the behest of the parties, and forbids a correction or amendment on the arbitrators own motion more than three business days after the award. We conclude that the modification made was beyond the reach of the arbitrators’ power. If an arbitral panel exceeds its authority, it provides grounds for a court to vacate that aspect of its decision. 9
II.
As a second ground to reverse, Smith points to the Union’s contractual limitation on its right of appeal to “arbitrator misconduct.” We note, however, that the Union did not appeal the merits of the arbitral award at all. As discussed above, the Union lodged its objection to Smith’s request to confirm based on the power of the arbitrators to modify the award, a question of law for the court. We do not find that the Union violated its agreement to waive appeal of certain matters.
III. CONCLUSION
By modifying the original award, the arbitration panel in this case exceeded the authority granted by the parties’ agreement to arbitrate. Consequently, we affirm the district court’s judgment vacating the modified award and confirming the original arbitration award.
AFFIRMED.
