• William J. Trunk handles high-stakes litigation matters. Bill represents corporations, their boards of directors, financial institutions, hedge funds, administrative agents and trustees, ad hoc groups and other investors, and individuals in all manner of complex commercial litigation. He has tried cases in federal and state courts across the country, argued appeals in the U.S. Circuit Courts of Appeal, and represented parties before the U.S. Supreme Court.

    Bill frequently represents hedge funds and other investors in litigation arising from complex refinancing and liability-management transactions. He represented a prominent hedge fund in bet-the-company litigation against telecommunications carrier Windstream Services, alleging that Windstream had defaulted under its bond indenture. Following a bench trial, the court sided with Bill’s client on every issue and awarded more than $300 million in damages. He represented holders of defaulted bonds in yearslong litigation against the Republic of Argentina, culminating in a $4.6 billion settlement. Bill also defends companies and their boards of directors against derivative lawsuits, breach of fiduciary duty claims, and related matters. He represented the former independent directors of a Guernsey-based fund sponsored by The Carlyle Group, successfully defending his clients against a $2 billion lawsuit brought by the fund’s liquidators.

    In addition to his trial work in state and federal courts around the country, Bill regularly handles appeals in the U.S. Circuit Courts of Appeal and the U.S. Supreme Court. He briefed and argued the Fourth Circuit criminal appeal of Jeffrey Sterling, a former CIA agent who was convicted under the Espionage Act for leaking classified material to a New York Times reporter. He also represented parties filing amicus briefs in support of the winning side in two landmark Supreme Court decisions: Murphy v. NCAA, overturning the decades-old federal ban on state-authorized sports betting, and National Labor Relations Board v. Noel Canning, clarifying the scope of the President’s recess-appointment power.
