Former Deputy Associate Attorney General Eric McArthur Rejoins Sidley in Washington, D.C.

Eric McArthur has rejoined Sidley Austin LLP in Washington, D.C., as a partner in its Supreme Court and Appellate practice. McArthur returned to Sidley after serving as Deputy Associate Attorney General in the U.S. Department of Justice (DOJ).

In a release, the firm said he will focus his practice on representing clients in appellate court proceedings as well as trial court litigation matters, particularly those involving critical motions and complex issues of constitutional, statutory and administrative law.

In his role as Deputy Associate Attorney General, McArthur assisted the Associate Attorney General in supervising and managing high-stakes litigation handled by the DOJ’s Civil and Environment and Natural Resources Divisions. He represented the DOJ in coordinating litigation with the White House Counsel’s Office and other federal agencies, including the Department of Health and Human Services, the Department of Labor, the Department of Commerce, the Department of State, the Department of Defense, the Department of Interior and the Environmental Protection Agency. McArthur also argued on behalf of the United States in significant cases in both the Second and Ninth Circuit Courts of Appeals.

“We are excited that Eric has rejoined the firm,” said Peter Keisler, co-leader of Sidley’s Supreme Court and Appellate practice. “The wealth of experience and sharp insights he gained through directly supervising and handling important cases will be critical in helping guide our clients through matters involving advocacy and negotiation with the Justice Department, as well as litigation involving federal agencies.”

Earlier in his career, McArthur served as a law clerk for both former Fourth Circuit U.S. Court of Appeals Judge J. Michael Luttig and U.S. Supreme Court Justice Clarence Thomas.
