Few lawyers have done more to champion the rights of consumers, businesses, and investors who have been harmed by anticompetitive conduct, fraud, and negligence than high-stakes litigator Stacey Slaughter.
Recognized by The Legal 500 as “smart, hard-working, collegial,” Ms. Slaughter is a partner and co-chair of the Antitrust and Trade Regulation Group at Robins Kaplan LLP, with decades-long experience in antitrust and consumer class action litigation, complex commercial litigation, as well as securities and financial markets litigation. The cases Ms. Slaughter has litigated have recovered more than $1 billion for victims of deceptive or unlawful conduct, and have included some of the largest, high profile, and most innovative cases arising under antitrust and federal securities laws. At home in the courtroom, Ms. Slaughter has litigated numerous cases to trial, arbitration, and resolution, with experience in courts and arbitration forums around the United States.
A Fierce Champion
For over 20 years, Ms. Slaughter has regularly served in court-appointed leadership roles representing clients whose rights have been compromised or who face significant commercial disputes, complex business problems, and novel legal issues. She currently represents cattle ranchers and industry trade groups alleging that the country's four largest meatpackers colluded to suppress the prices paid for cattle used in beef production. She represents a class of over 10 million U.S. merchants who allege Visa, Mastercard, and their member banks violated antitrust laws by charging supracompetitive interchange fees on card transactions—a case that has settled for a historic $5.6 billion. She also currently represents direct action plaintiffs alleging manipulation of the LIBOR benchmark in the billion-dollar multi-district litigation in the Southern District of New York against numerous bank defendants surrounding the BBA LIBOR-rigging scandal.
Among the other noteworthy results she has obtained on behalf of organizations and investors, Ms. Slaughter represented financial institutions in a class action lawsuit against Equifax regarding its unprecedented security failure, one of the largest data breaches in history that impacted an estimated 143 million Americans. She represented investors in an antitrust class action lawsuit against the largest private equity firms for a conspiracy to suppress the buyout price for public companies, which settled for $590.5 million. Ms. Slaughter represented an institutional investor to recover a confidential settlement amount for toxic, residential mortgage-backed securities. She also represented three institutional investors in a closely-held company to recover $40 million arising from a failed tax shelter instituted as part of a stock sale. Ms. Slaughter also recovered millions in a FINRA arbitration for a sovereign nation whose financial broker recommended investments in unsuitable, non-traded real estate investment trusts.

She is currently Co-chair of the Federal Bar Association's Minnesota Chapter Committee on Class Actions, Mass Tort, and MDL’s.
Among her many notable recognitions, Ms. Slaughter was recently ranked one of Lawdragon's 500 Leading Litigators in America (2023) and in the Chambers USA Guide for Antitrust in Minnesota (2022).

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.
