Paul Sampson is a litigation partner with a wealth of experience in all aspects of high-stakes litigation, including significant trial experience. He recently joined Kunzler Bean & Adamson’s litigation team after splitting a decade in Washington, D.C. at one of the nation’s leading trial litigation boutiques and at a top-10 ranked “big law” firm.

Paul has worked with clients in a variety of industries, including biotechnology, pharmaceutical, healthcare, consumer products, interstate shipping, energy, and financial services. He has represented clients in antitrust and consumer class actions; shareholder derivative actions; defamation lawsuits; and government investigation and enforcement actions involving the U.S. Department of Justice, the Securities and Exchange Commission, the Federal Trade Commission, state attorneys general, and the City of New York. He also represented a “special litigation committee” of a large pharmaceutical distributor’s board of directors in shareholder derivative litigation involving opioid distribution and executive compensation issues.

Paul has also successfully represented clients in appellate matters in federal and state appellate courts throughout the country. He has briefed dozens of appeals to the U.S. Supreme Court, several federal circuit courts, and several state supreme courts. And he recently prevailed after presenting oral argument to the District of Columbia Court of Appeals.

Prior to joining Kunzler Bean & Adamson, Paul practiced law for a decade in Washington, D.C. From 2016 to April 2021, Paul worked as an associate attorney, and later as counsel, for Wilkinson Walsh + Eskovitz LLP (now Wilkinson Stekloff LLP), a high-stakes, bet-the-company trial boutique that Paul joined at its founding in 2016. Paul’s representative matters at Wilkinson Walsh included, among others:

  • Larsen v. Philip Morris USA Inc. Member of the trial team that secured a complete defense verdict for Altria in state court on a $1.5 billion fraud claim following a six-week trial.
  • City & State of New York v. FedEx Ground Package Sys., Inc. Represented FedEx Ground in a $600 million lawsuit brought by the State and City of New York alleging that FedEx Ground improperly shipped untaxed cigarettes. Conducted multiple depositions, including the deposition of plaintiffs’ public health expert, and defended depositions of key company witnesses and trial experts. Prevailed in excluding plaintiffs’ public health expert from testifying at trial. Drafted summary judgment briefing that resulted in a dramatic reduction in potential damages and led to a favorable settlement shortly before trial.
  • Infuse (Medtronic) Prod. Cases. Conducted numerous depositions of treating physicians and plaintiffs’ experts in products liability bellwether cases involving a spine fusion product that settled on favorable terms before trial.
  • Essure (Bayer) Product Cases. Represented Bayer in bellwether litigation addressing suits filed by users of a birth control product. Defended depositions of two critical company witnesses before cases settled on favorable terms.
  • In re McKesson Corp. Derivative Litig. Represented Special Litigation Committee of the McKesson board of directors in shareholder derivative litigation involving opioid distribution and executive compensation issues. Helped negotiate a favorable settlement.

Prior to joining Wilkinson Walsh, Paul was an associate at Sidley Austin LLP where he gained significant litigation experience, including defending numerous fortune 500 companies subject to government criminal and civil investigations. At Sidley, Paul also drafted appellate briefs to multiple federal appellate courts, including briefing that persuaded the U.S. Supreme Court to reverse the Eleventh Circuit on a complicated fuel-excise taxation issue.

Throughout his career, Paul has maintained an active pro bono practice. Fluent in Spanish, he has successfully represented an unaccompanied minor in a petition for asylum, and he secured full custody of three children for an El Salvadoran immigrant following a multi-day evidentiary hearing. In early 2021, Paul presented oral argument to the District of Columbia Court of Appeals and won reversal of a federal agency order denying the employment compensation claims of a pro se petitioner.

At the beginning of his legal career, Paul served two judicial clerkships — for the Honorable Justice Thomas R. Lee of the Utah Supreme Court and for the Honorable Kent A. Jordan of the U.S. Court of Appeals for the Third Circuit.

Paul graduated magna cum laude from the J. Reuben Clark Law School at Brigham Young University, where he served as an Executive Editor of the law review. He received his undergraduate degree in history, with a minor in economics, from Brigham Young University.
