It is important for aggrieved parties to have their day in court and to have the best possible representation.


David Mitchell is a partner in Robbins Geller Rudman & Dowd LLP’s San Diego office and focuses his practice on antitrust and securities fraud litigation. He is a former federal prosecutor who has tried nearly 20 jury trials. As head of the Firm’s Antitrust and Competition Law Practice Group, he has served as lead or co-lead counsel in numerous cases and has helped achieve substantial settlements for shareholders. His most notable antitrust cases include Dahl v. Bain Cap. Partners, LLC, obtaining more than $590 million for shareholders, and In re Payment Card Interchange Fee and Merchant Discount Antitrust Litig., in which a settlement of $5.5 billion was approved in the Eastern District of New York. This case was brought on behalf of millions of U.S. merchants against Visa and MasterCard and various card-issuing banks, challenging the way these companies set and collect tens of billions of dollars annually in merchant fees. The settlement is believed to be the largest antitrust class action settlement of all time. 

Additionally, David served as co-lead counsel in the ISDAfix Benchmark action against 14 major banks and broker ICAP plc, obtaining $504.5 million for plaintiffs. Currently, David serves as court-appointed lead counsel in In re Aluminum Warehousing Antitrust Litig., City of Providence, Rhode Island v. BATS Global Markets Inc., In re SSA Bonds Antitrust Litig., In re Remicade Antitrust Litig. and In re 1-800 Contacts Antitrust Litig.
