The Open Public Meetings Act applies to “all meetings of a governing body of a public agency”. RCW 42.30.030. The act defines a “public agency” as “Any state board, commission, committee, department, educational institution, or other state agency which is created by or pursuant to statute, other than courts and the legislature.” RCW 42.30.020(1)(a) (Emphasis added).
The courts are explicitly exempt from the OPMA. (The Public Records Act doesn’t explicitly exempt the courts but the case of Nast v. Michaels has been interpreted as exempting courts from compliance with the PRA). Nast v. Michaels, 107 Wn.2d 300 (1986).
