Representative Matters

Serving as court-appointed co-lead counsel, Robins Kaplan reached a $5.6 billion antitrust class action settlement on behalf of a class of more than 10 million U.S. merchants who accepted Visa and Mastercard credit and debit cards for the purchase of goods and services. Plaintiffs alleged that Visa and Mastercard, as well as major card-issuing banks such as JPMorgan Chase, Bank of America, Citibank, Wells Fargo, and Capital One, violated antitrust laws and charged merchants who accept credit and debit cards supra-competitive fees on card transactions. The settlement, which was granted final approval in December of 2019 and affirmed on appeal in March of 2023, represents the largest settlement of a private antitrust action in the 130-year history of the Sherman Act. In re Payment Card Interchange Fee and Merchant Discount Antitrust Litigation, MDL No. 1720 (E.D.N.Y.)
