Matthew D. McGill is a partner in the Washington, D.C. office of Gibson, Dunn & Crutcher. He practices in the firm’s Litigation Department and its Appellate and Constitutional Law and Intellectual Property practice groups.

Mr. McGill is a Chambers-ranked appellate litigator and previously was named a national Rising Star by Law360, which identified him as one of ten appellate lawyers under 40 to watch. In 2016, the National Law Journal named him as a “Litigation Trailblazer” for his pioneering work against foreign sovereigns. He has participated in 21 cases before the Supreme Court of the United States, prevailing in 16. Spanning a wide range of substantive areas, those representations have included several high-profile triumphs over foreign and domestic sovereigns:

• Murphy v. NCAA (2018) – This “historic decision” (Sports Illustrated) struck down an Act of Congress as unconstitutional and clears the path for States across the country to legalize sports betting. By establishing that the federal government has no power to “dictate[] what a state legislature may and may not do,” this “landmark ruling” (USA Today) safeguards the power of States to govern themselves. The decision capped off nearly six years of litigation in which Mr. McGill represented the Governor of the State of New Jersey in defense of New Jersey’s efforts to legalize sports betting in the Garden State.
• Puerto Rico v. Franklin California Tax-Free Trust (2016) – Arguing before the Supreme Court on behalf of creditors that found themselves on the leading edge of Puerto Rico’s debt crisis, Mr. McGill successfully defended an injunction invalidating Puerto Rico’s emergency municipal bankruptcy legislation. The ruling protected bondholders against the “chance that the territory could write its own bankruptcy plan” (Wall Street Journal) and ensured that Congress would retain control over Puerto Rico’s rescue plan.
• Bank Markazi v. Peterson (2016) – In this important separation-of-powers case, Mr. McGill represented victims of the 1983 Beirut Marine Corps Barracks Bombing who hold judgments against the government of Iran. Ruling in favor of the Beirut Marines, the Supreme Court rejected arguments from Iran’s central bank that Congress had impermissibly invaded the province of the Judicial Branch by authorizing victims of terrorism to seize certain assets. The ruling allowed nearly $2 billion to be distributed to Iran’s victims.
• Argentina v. NML Capital, Ltd. (2014) – For ten years, Mr. McGill represented NML Capital in litigation against the Republic of Argentina in what the Financial Times called “the trial of the century in sovereign debt restructuring.” The Supreme Court’s decision confirmed the availability of discovery in aid of enforcement of money judgments against foreign sovereigns and helped set the stage for NML’s multi-billion-dollar settlement of its claims.
• Hollingsworth v. Perry (2013) – This “historic” decision (Washington Post) secured the right of same-sex couples in California to marry. The Supreme Court’s decision followed a landmark trial that had invalidated California’s voter-enacted ban on same-sex marriage, Proposition 8, for violating the Fourteenth Amendment’s guarantees of due process and equal protection of the laws.
• Citizens United v. Federal Election Commission (2010) – Hailed by the New York Times as a “doctrinal earthquake,” this decision overruled two Supreme Court precedents and established the First Amendment right of corporations to spend general treasury funds on speech activities to influence the outcomes of elections.

Outside the Supreme Court, Mr. McGill’s practice focuses on cases involving novel and complex questions of federal law, often in high-profile litigation against governmental entities. For example, he currently represents a creditor of the Commonwealth of Puerto Rico that is challenging Puerto Rico’s federally-appointed Oversight Board under the Constitution’s Appointments Clause. He also represents victims of the 1998 U.S. Embassy Bombings in appeals brought by the government of Sudan raising questions under the Foreign Sovereign Immunities Act.

In the intellectual property area, Mr. McGill regularly participates in significant copyright and patent cases before the Supreme Court and the courts of appeals. In the Supreme Court, he represented Nautilus in Nautilus v. Biosig, Microsoft in Microsoft v. AT&T and Microsoft v. i4i, and publisher John Wiley & Sons in Kirtsaeng v. John Wiley & Sons.

Mr. McGill also maintains an active pro bono practice. He currently represents three adoptive couples in a constitutional challenge to the Indian Child Welfare Act, and he represents persons born in American Samoa in their constitutional challenge to a federal statute that designates them “non-citizen nationals.” In 2008, he successfully defended Senator John McCain in cases contending that Senator McCain was not a “natural-born citizen” and therefore was ineligible to be President.

Prior to joining Gibson Dunn, Mr. McGill served as a Bristow Fellow in the Office of the Solicitor General at the U.S. Department of Justice. He clerked for the Hon. Joseph M. McLaughlin of the U.S. Court of Appeals for the Second Circuit and the Hon. John G. Roberts, Jr. of the U.S. Court of Appeals for the D.C. Circuit.

Mr. McGill earned a Bachelor of Arts degree, magna cum laude, from Dartmouth College in 1996. In 2000, he graduated from Stanford Law School, where he was elected to the Order of the Coif.

Mr. McGill is licensed to practice in New York and the District of Columbia and he has been admitted to practice before the Supreme Court of the United States, the United States Courts of Appeals for the First, Second, Third, Fourth, Fifth, Ninth, Tenth, Eleventh, District of Columbia, and Federal Circuits, and the United States District Courts for the District of Columbia and the Southern District of New York.
