The Ninth Circuit Court of Appeals has affirmed a dismissal of a consumer lawsuit against Costco Wholesale Corp. alleging mislabeling claims against VitaRain Tropical Mango Vitamin Enhanced Water Beverage. Maple v. Costco Wholesale Corp., No. 13-36089 (9th Cir., order entered May 9, 2016). The plaintiff had alleged the product was mislabeled because the product contains added caffeine, precluding the use of “natural” on the label. The district court dismissed the case because the plaintiff did not read the label before purchasing it; on appeal, the plaintiff asserted that he could amend the complaint to add “a subclass of plaintiffs who did read the relevant parts of the label.” Because he did not rely on the label, the plaintiff’s claim failed, and “the potential existence of other classes of which Plaintiff is not a member is irrelevant,” the court found. Further, the “district court abused its discretion by dismissing the action without prejudice,” the court held, and directed the lower court to enter a dismissal with prejudice.
