Mayer Brown Legal Update

Dec. 31, 2008), the Third Circuit vacated a district court's decision to certify a class in a significant antitrust lawsuit, and held that the lower court had failed to resolve disputed issues concerning whether each requirement of Federal Rule of Civil Procedure 23 had been satisfied.
