Francine Friedman Griesing, the former Greenberg Traurig shareholder suing the firm for gender discrimination in a proposed $200 million class action, has asked a Philadelphia federal judge to dismiss the law firm’s motion to compel arbitration or, at the least, change the venue.

On the same day Griesing filed her proposed class action against Greenberg Traurig in New York federal court, the law firm filed a petition in Philadelphia federal court to compel arbitration, which it said was required under the firm’s partnership agreement.
