Jason W. Anderson focuses on appellate advocacy in Washington and Oregon and works closely with trial teams to secure key rulings and preserve issues for appeal.
Jason has handled appeals in state and federal courts for over two decades. He draws on deep experience with complex legal questions and understands how appellate courts evaluate arguments, shape doctrine, and review trial court decisions.
Clients bring Jason into high‑stakes matters because he knows how to position cases for appeal and navigate the appellate process. He often works on appeals involving significant financial exposure, major commercial disputes, and legal issues that carry consequences beyond a single case. He has represented a broad range of clients, including over a dozen Fortune 500 companies.
Jason’s appellate victories include precedent-setting decisions like Matter of Estate of Petelle, 195 Wash.2d 661 (2020) (holding that a separation agreement that settles all marital property rights waives a spouse’s statutory right to intestate succession), and Keodalah v. Allstate Insurance Company, 194 Wash.2d 339 (2019) (disallowing insurance-bad-faith claims against claims adjusters).
Jason’s practice includes full briefing and argument, major motion work, and strategic advice during trial proceedings. He helps trial teams frame legal issues, preserve key points, and build a record that supports meaningful appellate review. He also counsels clients on appellate risk and the broader impact an appeal may have on future litigation.
Before joining Carney Badley Spellman, Jason clerked for the Honorable David H. Armstrong at the Washington Court of Appeals, Division Two. He attended law school on a presidential scholarship and served as executive editor of the Seattle University Law Review.
Away from the office, Jason enjoys hiking and paddle boarding with his Schnoodle dog and watching his son and daughter compete in collegiate sailing.
