The U.S. Court of Appeals for the Eighth Circuit reversed a lower court's order remanding a case to Missouri state court, as it determined Walmart had showed the amount in controversy exceeded $5 million.

U.S. Court of Appeals Judge Michael Joseph Melloy for the Eighth Circuit concluded Walmart had adequately shown the amount in controversy had exceeded $5 million, specifically that it had sold more than $5 million in cough suppressant products containing dextromethorphan hydrobromide (DXM) and featuring a "non-drowsy" label, in a May 24 opinion.
