John Elwood is the head of the firm's Appellate and Supreme Court practice. He has argued nine cases before the Supreme Court of the United States and appeared before most of the federal courts of appeals. He has successfully argued cases across a broad cross-section of subjects, with particular experience in environmental law, the False Claims Act, government contracting, and federal criminal law.
Mr. Elwood represented the petitioners before the Supreme Court in Kellogg Brown & Root v. United States ex rel. Carter, involving False Claims Act whistleblower issues and in Elonis v. United States, considering the intersection of free speech, social media and criminal threat statutes. The Court ruled for his clients in both cases. Mr. Elwood also has won mandamus three times from the Fourth Circuit and DC Circuit in the last five years, successfully invoking attorney-client privilege to protect from disclosure internal investigation documents generated under corporate compliance programs.
Mr. Elwood's work has earned him recognition as one of Washington's top Supreme Court lawyers (Washingtonian, 2013), as one of "a small group of lawyers" with an "outsized influence at the U.S. Supreme Court" (Reuters, 2014), as one of "the most successful petitioning attorneys" before the Supreme Court between 2012 and 2015 (Villanova Law Review, 2016), and as one of the country's most innovative lawyers (Financial Times, 2014). Chambers USA reports that "[t]he much-admired John Elwood is praised for his advocacy skills" (2013), and describes him as "phenomenal" (2014), a "brilliant writer" (2015), and "a much-loved and widely respected lawyer who is quick on his feet" (2010).
Mr. Elwood brings a wealth of experience to his role, having served as a former Assistant to the US Solicitor General and Senior Deputy in the Office of Legal Counsel at the US Department of Justice (2005-2009). He also clerked for Justice Anthony Kennedy (1996-1997).
