What happened
A proposed class action was filed against Costco Wholesale Corporation, apparently alleging fraud involving items sold by Costco. The complaint alleged there were thousands of proposed class members and that the aggregate amount in controversy exceeded $5 million. The court questioned whether the amount-in-controversy requirement was met, and the plaintiff voluntarily dismissed the case.
