Kaye Scholer has been hit with a legal malpractice suit by a former client that claims the New York law firm’s discovery mistakes forced it to enter into a $107 million antitrust settlement.

Dallas-based chemical and plastics giant Celanese Corp. announced June 13 it was paying that amount to resolve multidistrict litigation brought in federal court in North Carolina by several textile manufacturers that had accused the company of fixing prices in the market for polyester staple fibers. Kaye Scholer had represented Celanese in the disputes from March 2002 to July 2006.
