The gender discrimination class action that Sanford Wittels & Heisler is pursuing on behalf of five former female employees of KPMG is the latest in a string of sexual bias cases that the firm has brought against some of the biggest companies in the world.

On Thursday, a U.S. district court judge in Manhattan denied a motion by KPMG’s lawyers at Ogletree, Deakins, Nash, Smoak & Stewart to dismiss the claims, or in the alternative, to force each of the five plaintiffs to pursue her claims individually.
