Fried Frank Harris Shriver & Jacobson has responded forcefully to a former associate's $50m (£32m) lawsuit against the firm, reports The Am Law Daily.

The suit was filed in December by Julie Kamps, a Harvard Law School graduate who worked at Fried Frank for a decade before the firm allegedly fired her during the middle of an arbitration in January 2009.

Kamps has accused the firm of denying her partnership because she is gay, ignoring her complaints about sexual harassment and instructing lawyers to write exaggerated negative performance reviews of unpopular associates.

She also claims that litigation partner Janice Mac Avoy sexually harassed her, that partners told her to wear more feminine clothing, and that senior figures at the firm retaliated against her for complaining.

Kamps is being represented by Daryl Davis of employment firm Doman Davis.

In a response filed late last month, Fried Frank, represented by Proskauer Rose partner Bettina Plevan, denied all of Kamps's allegations and argued that Kamps failed to state a valid claim, failed to seek other remedies, and missed the statute of limitations deadline.

Proskauer also is defending Fried Frank in an employment discrimination case filed in June by a former document specialist. The plaintiff in that case, Ivory Fuller, alleges that Fried Frank failed to pay her overtime, denied her medical leave, and fired her after she complained. Fuller, who is black, also claims the firm discriminated against her based on her race.

A representative for The Goldsmith Law Firm, which is representing Fuller, declined to comment. Fried Frank has denied Fuller's allegations in that case.

A third former employee, Roseanne Zito, filed an employment discrimination case against Fried Frank in late November, court records show.
