Chadbourne & Parke on Monday formally asked a Manhattan federal judge to dismiss a high-profile gender bias suit filed against the firm two months ago by litigation partner Kerrie Campbell in Washington, D.C.

In its 25-page filing, Chadbourne’s lawyers from Proskauer Rose claim that Campbell and fellow plaintiff and former Chadbourne partner Jaroslawa Zelinsky Johnson lack standing to file a class action suit against the firm under current employment discrimination laws.
