Cozen O’Connor has been hit with a sex discrimination suit by a female lawyer who claims she was ousted from the firm in September 2005, less than a month after she filed a formal complaint of gender discrimination with the firm’s director of human resources.

In the suit, attorney Patricia Biswanger claims that when her political activities in Haverford Township became controversial, Cozen O’Connor employed a double standard by prohibiting her from using any “firm resources” for political work, while having no objection to the political activities of male attorneys.
