In this matter arising out of the purchase of a vehicle, the court considered whether parties may expand the scope of judicial review of an arbitration agreement governed by the Federal Arbitration Act (FAA), 9 U.S.C. §§ 1 to 16. The agreement here contained a clause that permitted a court to review an arbitrator's award for errors of New Jersey law. Guided by the United States Supreme Court's holding in Hall St. Assocs., LLC v. Mattel, Inc., 552 U.S. 576 (2008), the court concluded that when the FAA controls an arbitration agreement, its vacatur terms are exclusive and cannot be modified by contract. Therefore, the pertinent clause in the arbitration agreement is unenforceable and severable from the remainder of the agreement. The court affirmed the trial court's order dismissing plaintiffs' complaint seeking to vacate the arbitration award.
