David L. Lillehaug brings to JAMS a rare combination of high-level federal and state experience as a Minnesota Supreme Court justice and a United States attorney for the District of Minnesota, along with decades of large-firm, first-chair practice litigating complex civil and regulatory cases in federal and state courts and in arbitrations.

During seven years on the Minnesota Supreme Court, Justice Lillehaug sat on more than 600 cases and wrote over 140 opinions. Legal scholars have focused on his civil jurisprudence, including on the standards for dismissal and summary judgment. He was the court’s liaison to its committees on professional responsibility, evidence and alternative dispute resolution.

In private practice, Justice Lillehaug’s clients included Fortune 100 companies, his state’s highest-ranking public officials, the cities of Minneapolis and St. Paul, the University of Minnesota, tribal nations and pro bono litigants.

Justice Lillehaug has particular experience in matters at the intersection of civil, criminal and regulatory law, such as white-collar and corporate internal investigations. He has represented clients on all three sides of False Claims Act cases: governments, defendants and relators. 

Justice Lillehaug also has a deep background in real estate and construction litigation, including pursuing and defending claims for delay, acceleration, scope changes, mechanic’s liens, defective work and design malpractice. He was the founding chair of the construction law section of his state bar association and is an honorary fellow of the American College of Construction Lawyers.

Reflecting Justice Lillehaug’s standing in the legal community, his state’s U.S. senators have twice appointed him to committees to recommend new federal judges.
