A team of litigators from Debvoise & Plimpton last week shut down $14.5 billion qui tam suit against insurance and financial services providers Prudential, John Hancock, AXA, Guardian, MassMutual and TIAA in New York state court.

In what the firm called “a total victory” for its clients, Justice Andrea Masley of the Supreme Court of the State of New York, County of New York dismissed the qui tam suit with prejudice and denied the plaintiff’s request to re-plead.
