Mathew L. Harrington

Shareholder | Seattle


Over the better part of two decades as an attorney and commercial litigator, Mat Harrington has taken over 20 cases to verdict or arbitration decision as lead or co-lead counsel, some of which involved claims worth hundreds of millions of dollars. He has argued numerous appeals and litigated successfully before the U.S. Supreme Court. He has represented individuals and entities in a wide array of industries and in venues ranging from county courthouses to an arbitration in the New York Times building in Manhattan. His practice emphasizes employment law, trust and estate litigation, and Indian law.

Mat’s litigation experience is broad. He has advocated for clients in lawsuits relating to employment law, non-compete agreements, trusts and estates, fiduciary duties, public disclosure laws, the Public Records Act, antitrust law, class actions, breach of contract, deceptive trade practices, fraud, and trade secret misappropriation. He is frequently called upon to advise professionals and Boards of Directors in disputes pertaining to duties, departures, and responsibilities. He also offers mediation services to parties seeking a neutral’s assistance to mediate a dispute.

Mat handles all aspects of complex litigation — from pre-suit investigation and discovery through dispositive motion practice and trial. He was counsel of record in Washington State Department of Licensing v. Cougar Den, 139 S. Ct. 1000 (2019), a landmark U.S. Supreme Court decision affirming a case he argued and prevailed on before the Washington Supreme Court, announcing that the Treaty of 1855 granted Yakama Nation members the right to travel the public highways of the United States free from taxes which encumber that treaty right. His representation of the Tulalip Tribe helped contribute to the passage of a law providing that tribes and the State of Washington may share sale tax receipts for sales occurring on reservations.

In 2016, Mat was named one of the Top 100 Lawyers in Washington State by Washington Super Lawyers. For the past 14 years, he has been recognized as a “Super Lawyer” and a “Rising Star.” He currently serves on the Executive Committee of the firm.

In addition to his experience in commercial litigation, Mat has a deep commitment to the public interest, arguing a 2019 case before the Washington Supreme Court that that State of Washington must improve the quality of public defense services provided to indigent juveniles accused of offenses.
