Nearly two months after voting to expel a former partner who is leading a $100 million gender bias suit against Chadbourne & Parke, the firm failed on Wednesday to escape a proposed class action alleging it's run by an ” all-male dictatorship.”

U.S. District Judge J. Paul Oetken in Manhattan shot down Chadbourne's motions for summary judgment and to dismiss class and collective action claims in a suit led by former partner, Kerrie Campbell, and two other former Chadbourne partners—Mary Yelenick, who remains at the firm in an of counsel role, and former Kiev, Ukraine, office leader Jaroslawa Zelinsky Johnson.

The decision comes on the heels of new filings lodged late Tuesday in a similar but separate suit in Washington, D.C., federal court against Proskauer Rose. That firm filed pleadings late Tuesday seeking dismissal of an unnamed woman partner's gender bias claims and a $50 million damages claim.
