Norton Rose Fulbright, now a defendant in a $100 million gender discrimination lawsuit that was originally filed against merger partner Chadbourne & Parke, is facing new claims that it aided and abetted Chadbourne’s conduct by encouraging the firm to fire named plaintiff Kerrie Campbell before the merger deal closed.

A newly amended complaint also adds claims by a third plaintiff, Mary Yelenick, that Chadbourne pressured female partners to sign a letter disavowing the lawsuit.
