Kannon K. Shanmugam

Partner, Williams & Connolly, LLP

Kannon Shanmugam is a partner focusing on Supreme Court and appellate litigation. He has been described as a "wunderkind" (Am Law Litigation Daily) and "rising star" (Legal Times) of the Supreme Court bar. He has argued ten cases before the Supreme Court, more than any other lawyer in the firm's history except Edward Bennett Williams. In 2009, he argued Merck & Co. v. Reynolds, which concerned the statute of limitations for private securities-fraud actions, and Hawaii v. Office of Hawaiian Affairs, which involved a challenge to an injunction barring the State of
Hawaii from selling public lands held in trust for Native Hawaiians. He is currently representing the petitioner in Textron v. United States, a closely watched case concerning the scope of the work-product privilege.

Mr. Shanmugam joined the firm in 2008 after serving as an Assistant to the Solicitor General in the Department of Justice. He
was the first lawyer to join the firm directly as a partner for 22 years. While representing the United States before the Supreme
Court, he developed a particular expertise in securities, antitrust, and complex criminal litigation. He successfully argued Tellabs v. Makor Rights, which concerned the standard for pleading state of mind in a federal securities-fraud action; Weyerhaeuser v. Ross-Simmons, which involved the standard for a claim of predatory bidding under the federal antitrust laws; and Oregon v. Guzek, which concerned the type of mitigating evidence that can be used at sentencing in capital cases.

During his tenure at the Justice Department, Mr. Shanmugam was also responsible for preparing the briefs of the United States in a number of other significant Supreme Court cases, including Stoneridge Investment Partners v. Scientific-Atlanta, a case involving the availability of “scheme liability” under the federal securities laws; United States v. Atlantic Research, a case
concerning the availability of actions for reimbursement of environmental cleanup costs under the Comprehensive
Environmental Response, Compensation, and Liability Act; and Arthur Andersen v. United States, an appeal by Arthur Andersen from its conviction for obstruction of justice in connection with the collapse of Enron. He received a commendation from the Justice Department's Environmental and Natural Resources Division for his work on environmental litigation.

Before joining the Justice Department, Mr. Shanmugam was an associate at the law firm of Kirkland & Ellis, where he worked on a variety of Supreme Court and appellate matters. Most notably, he was responsible for preparing the brief on behalf of Senator Mitch McConnell and other challengers to the McCain-Feingold campaign-finance law in McConnell v. FEC. He also represented the plaintiffs in Granholm v. Heald, a successful challenge to a state law prohibiting the direct shipment of wine to consumers.

Mr. Shanmugam was born in Lawrence, Kansas, the son of Indian immigrants. He grew up there and was co-valedictorian of his class at Lawrence High School. He went to Harvard at age 16, where he majored in classics and graduated summa cum laude. After being selected as a Marshall Scholar, he obtained a master’s degree in classics from the University of Oxford. He then returned to Harvard Law School and graduated magna cum laude in 1998; there, he served as executive editor of the Harvard Law Review and argued the case for the winning side in the moot court competition. After law school, he served as a law clerk to Justice Antonin Scalia on the United States Supreme Court and then-Judge J. Michael Luttig on the United States Court of Appeals for the Fourth Circuit.

Within the last year, Mr. Shanmugam was selected as one of Washingtonian magazine's "Top Supreme Court Lawyers,” and Law 360 featured him as one of its ten “Appellate Lawyers Under 40 To Watch.” He also has been listed as one of "Washington’s 40 Under 40" (National Law Journal) and "40 Top Lawyers Under 40" (Washingtonian). In a 2007 profile on "Up and Coming Lawyers" who are "on the fast track to making a significant impact on the profession," Lawyers USA described him as "a Supreme Court whiz kid." In 2006, The Topeka Capital-Journal named him as one of its
"Distinguished Kansans of the Year," citing his work "on the front lines of justice." In 2005, Washingtonian listed him as one of its "20 People to Watch." He was also featured by the Associated Press in a story on "The Supreme Court of Tomorrow."

Mr. Shanmugam has spoken extensively on the Supreme Court and legal issues. He currently serves on the boards of trustees of the Supreme Court Historical Society, the American Inns of Court, and the Association of Marshall Scholars. He has served as secretary of the Edward Coke Appellate Inn of Court, and as a member of the executive committee of the American Bar Association's Council of Appellate Lawyers. He is a member of the firm's pro bono committee and is active in the Washington community. He currently serves on the vestry of St. Francis Episcopal Church in Great Falls, Virginia, and has worked as a volunteer teacher at Anacostia High School in Southeast Washington.
