On July 16, 2026, the First Department issued a decision in Matter of Light & Wonder, Inc. v. Mohawk Gaming Enters. LLC, 2026 NY Slip Op. 04474, upholding a court’s refusal to vacate a class arbitration award, explaining:
Petitioners failed to establish any of the limited statutory bases for vacating an arbitration award under the Federal Arbitration Act (FAA) (9 USC § 1 et seq.), which, according to the parties’ agreement, governs review of the arbitrator’s class determination award. Petitioners did not establish that the arbitrator manifestly disregarded the law as set forth in Lamps Plus v Varela (587 US 176 [2019]) and Stolt-Nielsen S.A. v AnimalFeeds Intl. Corp. (559 US 662 [2010]), in rendering his award. Petitioners failed to show that the arbitrator knew of a governing legal principle that was well defined, explicit, and clearly applicable, and yet refused to apply it or ignored it altogether.
Petitioners argued that under Lamps Plus and Stolt-Neilsen, the arbitrator was required to review each absent class member’s contract to determine whether each member affirmatively consented to class arbitration before certifying the class.
However, as Supreme Court properly concluded, Lamps Plus and Stolt-Neilsen address the propriety of class arbitration under the arbitration clauses at issue in those cases. Neither case addresses the issue of class certification, nor do they discuss whether the same analysis would be relevant in the context of class certification. As a result, even assuming that petitioners’ interpretation of Lamps Plus and Stolt-Nielsen is valid, it cannot be said that the law is so well defined, or so clearly applicable to the absent class member contracts at issue, that the arbitrator’s findings constituted a manifest disregard of the law. This conclusion is especially true in light of the fact that judicial review of arbitration awards is extremely limited in scope.
Additionally, the arbitrator did not exceed his powers within the meaning of the FAA, because the record does not support a conclusion that the arbitrator strayed from his delegated task of interpreting a contract. The arbitrator addressed relevant authorities, including Lamps Plus and Stolt-Neilsen; reviewed the arguments and the documents submitted by both parties, including sample clauses from the contracts of absent putative class members; and assessed in detail the relevant American Arbitration Association rule for class certification. After the arbitrator conducted this analysis, he determined that the class members’ agreements were substantially similar, and that any of the narrow differences in the agreements did not preclude certification of the class. Notwithstanding petitioners’ argument that it was improper for the arbitrator to consider the practical consequences of adopting their interpretation of Lamps Plus, those considerations were only one component of the arbitrator’s analysis, and he fully set forth his rationale for disagreeing with petitioners’ interpretation of Lamps Plus and its applicability to this case.
