A little more than a month after being sued by recently departed partner Constance Ramos in a California state court, Winston & Strawn is seeking to push her sexual discrimination and retaliation complaint into arbitration.

In court papers filed last week in San Francisco County Superior Court, Winston & Strawn and its lawyers claimed that Ramos is bound by the firm’s partnership agreement to arbitrate any “disputes or controversies” arising from her time at the firm, which she joined in 2014 from Hogan Lovells.
