    • The National Football League in the defense and landmark settlement, upheld on appeal, of hundreds of lawsuits filed by thousands of former NFL players seeking to hold the League liable for allegedly concealing the risks associated with concussions sustained while playing professional football. We continue to serve as counsel for the NFL in the implementation of the 65-years settlement.
    • Citigroup in several major litigation and regulatory enforcement matters, including:
      • a complete defense win in an arbitral panel ruling, subsequently upheld by a federal district and an appellate court, in a $7.5 billion ICDR arbitration brought by the Abu Dhabi Investment Authority (ADIA);
      • a multi-year federal grand jury investigation of its compliance with BSA/AML requirements that resulted in a non-prosecution agreement and a significantly reduced penalty;

    • A Special Committee of the Board of Directors of Credit Suisse in an internal review of Credit Suisse’s relationship with hedge fund Archegos Capital and the events leading to losses incurred by the bank as a result of Archegos’s default, culminating in the release of a 165-page report detailing observations and recommendations for remedial measures.
    • News Corp and News America Marketing (NAM) in several antitrust matters, including most recently the defense of a $700 million monopolization claim brought by competitor Valassis Communications, which Paul, Weiss successfully tried to a jury in a three-week trial in 2021 in the Southern District of New York; securing the dismissal of another antitrust claim by Valassis alleging that NAM violated a consent order resolving an earlier dispute through unlawful bundling and tying; and the favorable settlement of a significant antitrust class action brought by customers of NAM’s in-store marketing products, including consumer products companies Dial, Heinz and Smithfield Foods, claiming that NAM illegally monopolized an alleged market for in-store promotional services by engaging in a variety of alleged exclusionary practices.

    • Blackstone Alternative Asset Management (BAAM) in securing a landmark appellate win in the Kentucky Supreme Court concerning a $50 billion derivative claim brought by beneficiaries of Kentucky's public pension fund. The ruling brought the long-running case to a close, with the Kentucky Supreme Court unanimously holding that defined-benefit beneficiaries of the state's pension plans lacked statutory and constitutional standing to bring their claims on behalf of the fund of the Commonwealth. With a number of states contending with underfunded pension plans, the lawsuit has been viewed as a critical test case for whether beneficiaries of underfunded public pension plans may assert claims against third-party asset managers on behalf of those plans, and this decision has significant implications for the future of such claims.
