Returning to the firm where she began her legal career, Lisa Blatt is leaving Arnold & Porter to rejoin Williams & Connolly, where she will head the firm’s Supreme Court and appellate practice.

Blatt has argued 37 cases before the U.S. Supreme Court—more than any other woman—and won 33 of them (two are pending). Her Feb. 5 move to Williams & Connolly comes as the firm’s current appellate practice head, Kannon Shanmugam, decamps to Paul Weiss, Rifkind, Wharton & Garrison, creating an opening for a new appellate leader at the Washington, D.C.-based litigation firm.

Blatt joined Williams & Connolly in 1990 as an associate and departed three years later for the general counsel’s office at the Department of Energy, followed by the Office of the Solicitor General, where she worked from 1996 to 2009.

At Arnold & Porter, Blatt headed the firm’s appellate and Supreme Court practice. A firm spokeswoman did not respond to an email seeking comment on Sunday.

Blatt’s husband, David Blatt, is a partner at Williams & Connolly focusing on general civil and commercial litigation, products liability litigation and professional liability litigation. They met when Blatt joined the firm in 1990.

Williams & Connolly chairman Joe Petrosinelli in a written statement said, “We are thrilled to have Lisa come home. She has remained a close friend to many of us throughout her time away from the firm, and we take great pride in her amazing accomplishments. We look forward to having her represent our clients in appeals courts everywhere, including the United States Supreme Court. Welcome home, Lisa.”
