The practice is led by renowned appellate litigator Lisa Blatt, who has argued 55 cases—more than any woman in history—and has an 82% win rate in cases decided. The practice argued 22 Supreme Court merits cases over the past five Terms—a record for any group in private practice. During the past two Terms, Williams & Connolly argued eight merits cases.

The practice features a deep bench of attorneys with a wealth of experience in and out of government. Practice head Lisa Blatt served for 13 years in the Solicitor General’s Office, clerked for Justice Ruth Bader Ginsburg, and has won virtually every award or recognition in the legal field, including being named The American Lawyer’s 2021 “Litigator of the Year.” Partner Amy Saharia, who clerked for Justice Sotomayor, has argued more than thirty appeals, including three Supreme Court cases in the past several Terms. Partner Luke McCloud, who clerked for Justice Sotomayor and then-Judge Kavanaugh, has argued four Supreme Court cases in the past three Terms and served in the U.S. Department of Justice as Assistant to the Solicitor General before his return to Williams & Connolly. The practice counts Supreme Court clerks from a majority of chambers, and the firm’s ranks include 16 former Supreme Court clerks and approximately 200 former clerks from all 13 federal courts of appeals. 

Partners and associates alike routinely argue in federal and state appellate courts across the country, including in a wide array of pro bono matters ranging from immigration and asylum work to representing religious groups and nonprofits in the Supreme Court on religious liberty issues.
