A former Winston & Strawn partner suing the firm for gender bias is appealing her case being sent to arbitration.

In court papers filed Friday with California's First District Court of Appeal, Constance Ramos and her legal team pushed back against a late November ruling by a San Francisco judge that sent her case to arbitration. A status conference in the litigation set for Jan. 31 had recently been pushed back to August as a result of that decision.

Ramos, a former Hawaiian high school classmate of President Barack Obama, sued Winston & Strawn last August in San Francisco County Superior Court. Ramos accused the firm of discriminating and retaliating against her after a male colleague she joined Winston & Strawn with in 2014 resigned from the firm less than two years later.
