One of the partners involved in a gender bias lawsuit against Ogletree Deakins Nash Smoak & Stewart has opened a new front in the dispute, filing a lawsuit on Wednesday under California's Private Attorneys General Act.

Lawyers for Tracy Warren, a former equity shareholder at Ogletree, lodged the suit in San Diego federal court on behalf of her and other women lawyers at the law firm. Previously, Warren opted into a proposed class action filed in San Francisco early in 2018 by lead plaintiff Dawn Knepper, another former Ogletree shareholder.

Warren and Knepper have both landed at Buchalter after leaving Ogletree, and they're represented in the gender bias cases by Sanford Heisler Sharp, a firm that has been instrumental in a wave of recent lawsuits alleging unfair pay and promotion practices at large law firms.
