On June 20, the Supreme Court concluded that marketing denial orders (MDOs) issued by the Food and Drug Administration (FDA) can be challenged not only by the applicants (typically, the manufacturer or importer of the products), but also by retailers who would sell such products. As a result, more challenges to MDOs are likely to be brought before the U.S. Court of Appeals for the Fifth Circuit, where litigants have generally had greater success to date in challenging MDOs relative to other appellate courts.
