Some of Kennedy’s recent representative matters include:

Antitrust

  • Representing the Blue Cross Blue Shield Association (“BCBSA”) and more than a dozen member plans in consolidated multidistrict antitrust class action litigation—one of the largest class actions in the country—brought by putative classes of healthcare providers and health insurance subscribers alleging that the Association and its members have used the Association’s agreements to fix prices and limit competition. She also represents BCBSA and various member plans in related opt‑out litigation across the country brought by large self‑funded subscribers and providers.
  • Representing BCBSA and several member plans in antitrust litigation brought by TranS1, a medical device company, alleging the Association and its members conspired to limit access to plaintiff’s AxiaLIF technology for performing spinal fusions.
  • Represented Florida Blue in winning the dismissal in February 2021 of antitrust litigation filed by competitor Oscar Insurance alleging that Florida Blue’s exclusive agency relationships violated the Sherman Act and state competition laws.
  • Represented American Express (“Amex”) in a lawsuit in the U.S. District Court for the Eastern District of New York brought by the Department of Justice and 17 state attorneys general alleging that certain provisions in Amex’s merchant agreements violate antitrust laws. The case culminated in a seven‑week bench trial, which was followed by successful appeals in favor of Amex in both the Second Circuit and the Supreme Court.

Won a significant portion of the case on summary judgment followed by a further victory after trial on the remaining counts, resulting in a substantial financial recovery for the client.

Securities and Shareholder Derivative Litigation

  • Represented GreenSky and its officers and directors in class action securities litigation in New York state and federal courts alleging disclosure deficiencies in connection with GreenSky’s May 2018 initial public offering.

  • Represented Chemed and various individual defendants in consolidated shareholder derivative litigation in Delaware federal court arising from alleged improper billing of Medicare and Medicaid.
