Chair of the Supreme Court and Appellate Practice Group and managing partner of the Washington office, Kannon Shanmugam is widely recognized as one of the nation's top appellate lawyers. He was named 2021 Appellate Litigator of the Year by Benchmark Litigation. Kannon has argued 32 cases before the Supreme Court, including four cases in the current 2020-2021 term. A recent study found that, over the last five years, Kannon had the highest rate of successful petitions for review of any Supreme Court practitioner. He was lead counsel in the successful constitutional challenge to the structure of the Consumer Financial Protection Bureau, described by the Wall Street Journal as the “constitutional case of the year.”
Prior to private practice, Kannon served as an Assistant to the Solicitor General at the U.S. Department of Justice. He also served as a law clerk to Supreme Court Justice Antonin Scalia and to Judge J. Michael Luttig of the U.S. Court of Appeals for the Fourth Circuit.
One longtime Supreme Court reporter recently said that Kannon “has perhaps the most eloquent and elegant manner … that I’ve ever seen in my 40 years covering the Court,” adding that he “projects calm, confidence, and authority from the moment he takes to the lectern.” In ranking Kannon in Band 1 of appellate advocates nationwide, Chambers USA described him as “absolutely extraordinary” and praised him as “smooth, unflappable, effective, and elegant … an incredible lawyer in all respects.” Benchmark Litigation noted that Kannon is “one of the most respected and admired appellate practitioners” in the country.
