Southwest Airlines sought judicial review of the arbitration award, arguing that the arbitrator exceeded his authority by ignoring the CBA’s terms. Upon review to the district court, the court cited the narrow scope of judicial review for labor arbitration awards and declined to overturn the arbitrator’s ruling. On appeal, the Fifth Circuit reversed and remanded, holding: “Despite the significant deference that we must pay to arbitrators, this case is an example of when an arbitrator goes too far.” The appellate court ruled that in concluding that the effective date was the date the agreement was signed, the arbitrator “ignored the unambiguous terms of the CBA.” Southwest Airlines Co. v. Local 555, Transport Workers Union of America AFL-CIO, No. 18-10122 (5th Cir. January 9, 2018).
