Plaintiffs were seeking $28 million in damages. After remand from the Eighth Circuit Court of Appeals from an earlier dismissal, on September 30, 2012, the U.S. District Court for the Western District of Missouri again dismissed plaintiffs' claims because of discovery abuses resulting from plaintiffs’ failure to preserve, and permitted destruction of, key financial information.
