Lawyers for former Steptoe associate Ji-In Houck—a 2011 Georgetown University Law Center graduate now working as a litigator at the Stalwart Law Group in Los Angeles—filed a brief on Monday opposing Steptoe's motion to compel arbitration of Houck's gender bias allegations.

The filing marks the latest in the case since Steptoe, on Aug. 10, forcefully denied Houck's allegations that the firm has a pay gap between men and women lawyers. Houck, who initially joined Steptoe as a contract lawyer and later became an associate, alleges that she was paid less than her male and other peers at the firm, despite taking on similar work.
