Ted Sampsell-Jones


Ted began teaming with Riordan & Horgan in 2003 after clerking for the Ninth Circuit with Judge William Fletcher. Ted thereafter played a lead role in drafting appeals in numerous cases handled by the firm, including both Barry Bonds appeals in the Ninth Circuit.  Several years ago, Ted argued to an en banc panel of the Ninth Circuit in United States v. Nosal, which led to a victory for the client and a watershed limitation of the Computer Fraud and Abuse Act. More recently, he argued United States v. Shayota, which presents a groundbreaking question about the scope of the 6th Amendment’s Confrontation Clause and its exceptions at common law. In all of these cases, Ted has combined traditional doctrinal argument with deep historical research and academic rigor, leading to novel and compelling arguments.

In addition to his work with Riordan & Horgan, Ted is a tenured professor of law at Mitchell Hamline School of Law in St. Paul, Minnesota. Ted has published articles in leading law reviews, with a particular focus on criminal evidence law. His articles have been cited by courts and scholars around the country. Recognized as a leading scholar of evidence law, Ted was appointed by the Minnesota Supreme Court to serve as chair of the Minnesota Rules of Evidence advisory committee.

Ted also maintains an active pro bono practice in Minnesota, where he has argued appeals in cases ranging from city ordinance violations to homicide.  In his pro bono practice, he has succeeded in overturning convictions for indigent defendants in multiple cases. He was recently named one of the “Attorneys of the Year” by Minnesota Lawyer.

Ted earned his law degree from Yale Law School, where he was an editor for the Yale Law Journal and a Coker Fellow. While in law school, he worked in the appellate group at Jenner & Block in Washington D.C. He earned his bachelor's degree from Dartmouth College, where he graduated summa cum laude, ranked in the top five of his class, and was also awarded the Story Prize for best honors thesis in philosophy.
