Members of Mallinckrodt PLC's board of directors are facing a putative class action alleging they defrauded investors during the pharmaceutical company's bankruptcy proceedings.

Plaintiff Darrel Edelman, represented by Haviland Hughes, filed the suit on behalf of himself and a proposed class of "potentially thousands" of other Mallinckrodt investors who opted out of individual releases offered during Mallinckrodt's Chapter 11 bankruptcy.
