Grayhawk Law was founded by Matthew A. Seligman, an experienced federal litigator and constitutional law scholar. Before founding the firm, Mr. Seligman practiced at Kellogg, Hansen, Todd, Figel & Frederick in Washington, D.C., and at Stris & Maher in Los Angeles. His work spans trial and appellate litigation in federal courts, including the courts of appeals and the Supreme Court of the United States.

Mr. Seligman has represented clients in cases raising novel and consequential questions of constitutional and statutory interpretation, particularly in areas where legal doctrine intersects with democratic processes and institutional design. He has also written extensively on constitutional law and election administration, and his scholarship has been cited by courts, policymakers, and the media.

In addition to his litigation practice, Mr. Seligman is an accomplished constitutional scholar. He serves as a non-resident fellow at the Constitutional Law Center at Stanford Law School. Previously, he was a Climenko Fellow and Lecturer on Law at Harvard Law School, a fellow at the Center for Private Law at the Yale Law School, and a visiting assistant professor at Cardozo School of Law. His scholarship has been published in leading law reviews, including the Stanford Law Review, the Michigan Law Review, and the Vanderbilt Law Review. In 2024, his book How to Steal a Presidential Election co-authored with Lawrence Lessig was published by the Yale University Press.

His public writings have appeared in the New York Times, the New Republic, Slate, and other publications. He appears on CNN, MSNBC, and other news channels discussing legal issues of public importance.

Mr. Seligman holds a J.D. from Stanford Law School, a Ph.D. in moral and political philosophy from New York University, and a B.S in mathematics and a B.A. in philosophy from Stanford University. After law school, he clerked for the Honorable Judge Douglas H. Ginsburg on the United States Court of Appeals for the District of Columbia Circuit.
