Luna Ngan Barrington


Luna Ngan
Luna Barrington is a partner in Weil’s Complex Commercial Litigation practice, where she represents clients in high-stakes, bet-the-company litigations across the country including antitrust litigation, consumer class actions, complex commercial disputes and multi-district litigations.

Her recent work has included defending Serta Simmons Bedding in multiple lawsuits challenging a first-of-its kind transaction in the leveraged loan market; representing Visa as trial counsel in an antitrust action in Texas federal court against its competitor Pulse; representing Cleveland-Cliffs, one of the largest global steel companies in the country, in a high-profile multi-district litigation against two of the nation’s four major Class I railroads alleging antitrust violations; and representing biotechnology giant United Therapeutics in a series of RICO cases challenging UT’s charitable donations that help patients secure UT’s life-saving treatments.

Additional notable experience includes:

  • Successfully defending one of the few antitrust class actions tried to verdict in recent years – with nearly a billion dollars in damages at stake – on behalf of C&S Wholesale Grocers in Minnesota federal court, and sustaining that victory before the Eighth Circuit.
  • Winning an Eleventh Circuit victory for Farmers Insurance in an industrywide antitrust MDL regarding insurance carriers’ reimbursement of auto body shops for repair work.
  • Securing a complete arbitration trial victory for a major e-commerce company in a nine-figure contract dispute relating to a multi-year operating agreement with a former business partner. The award followed a five-day evidentiary hearing and three rounds of pre- and post-trial briefing.
  • Serving as a key member of the trial team that won a complete defense verdict for Johnson & Johnson in New Jersey state court following a four-week jury trial alleging that exposure to trace amounts of asbestos in J&J’s Baby Powder caused cancer. The trial defense victory for J&J stemmed the tide of hundred-million-dollar plaintiff verdicts in the talc mass tort litigation.
  • Successfully defending international chemicals and energy company Sasol Limited in a $200 million securities class action alleging that the company made false or misleading statements.

Luna also has an active pro bono practice. Most recently, she secured a preliminary injunction enjoining the implementation of a statute that would have banned nearly all abortion across the state of North Dakota. After a week-long bench trial, she also secured a complete victory for a pro bono client in a Hague Convention proceeding. And in 2017, Luna was a member of the trial team that successfully challenged the enactment and enforcement of an Arizona state statute as discriminatory under the First and Fourteenth Amendments of the Constitution.

Luna is active in Firm and other professional organizations and focuses her time on mentoring, diversity, and development. Currently, she serves as a co-leader of AsianAttorneys@Weil, Weil’s global affinity group dedicated to the recruitment, retention, and professional development of Asian attorneys. Luna also is an active member of the Asian American Bar Association in New York (AABANY), and serves as co-chair of AABANY’s Litigation Committee.
