Bonny Sweeney


Bonny E. Sweeney, a leading antitrust litigator, is a Partner in the San Francisco office of Hausfeld. Sweeney has represented clients in some of the most significant antitrust cases in the United States in the last 20 years. She served as co-lead counsel in In re Payment Card Interchange Fee and Merchant Discount Antitrust Litig. (E.D.N.Y.), which resulted in a settlement of $5.7 billion, likely the largest private antitrust class action settlement in history. Following the settlement, Judge John Gleeson of the Eastern District of New York applauded counsel’s “skill and tenacity” in achieving an extraordinary result for their clients. Sweeney, together with Hausfeld, also served as co-lead counsel in In re Aftermarket Auto Lights Antitrust Litig. (C.D. Cal.), which settled for more than $50 million, and in which they obtained a landmark decision denying a leniency applicant’s bid for reduced civil damages under the Antitrust Criminal Penalty Enhancement and Reform Act (ACPERA), because the defendant had not provided satisfactory or timely cooperation under the statute.

The Daily Journal recognized these legal achievements in May 2014, naming Sweeney as one of the Top Women Lawyers in its Annual List of 100 Leading Women Lawyers in California. Sweeney was also named as Litigator of the Week by Global Competition Review on October 1, 2014 for successfully defeating Apple’s bid for summary judgment in In re iPod iTunes Antitrust Litig. (N.D. Cal.). Bonny was also lead trial counsel for the plaintiff class in In re iPod iTunes Antitrust Litig., which was tried to a jury in 2014.

Sweeney was also one of the trial lawyers in Law v. NCAA/Hall v. NCAA/ Schreiber v. NCAA (D. Kan.), in which the jury awarded $67 million to three classes of college coaches. She has participated in the successful prosecution and settlement of numerous other antitrust and unfair competition cases, including In re Currency Conversion Fee Antitrust Litig. (S.D.N.Y.), which settled for $336 million.
