In Garza v Swift Transportation Co, Inc, the Arizona Supreme Court held that the court of appeals lacked jurisdiction to entertain an appeal from an order denying a motion for class certification. The plaintiff, a truck driver, had filed a class action complaint on behalf of drivers who had contracted with the defendant trucking company, alleging that the company systematically underpaid its drivers. The trial court denied class certification. The court of appeals assumed appellate jurisdiction and vacated the lower court’s ruling. The Arizona Supreme Court vacated the decision of the court of appeals on two primary grounds. First, the court relied on the U.S. Supreme Court’s decision in Coopers & Lybrand v. Livesay, which concluded that class certification orders were not independently appealable as a matter of right. Second, the court concluded that the Arizona statute providing for appellate jurisdiction essentially limited review to appeals from final judgments and the denial of class certification did not fall within any of the statutory exceptions. The court’s holding expressly overruled Reader v. Magma- Superior Copper Co., a 1972 decision in which the Arizona Supreme Court had determined that a narrow exception to statutorily mandated finality applied to denials of class certification.
