The answer depends more on the subcommittee’s authority and activities than on its “advisory” label.
The OPMA (Ch. 42.30 RCW) applies to agency “governing bodies,” which can include "any committee thereof when the committee acts on behalf of the governing body, conducts hearings, or takes testimony or public comment."
Truly advisory committees that only conduct internal discussions and advise governing bodies are not subject to the OPMA. See Citizens Alliance v. San Juan County (2015). But even subcommittees that are labeled “advisory” can act on a governing body’s behalf by exercising the body’s actual or de facto decision-making authority. This can happen when a governing body gives its decision-making authority to an advisory committee, or when a governing body routinely approves an advisory committee’s recommendations without discussion.
Identifying a subcommittee’s roles and responsibilities by reviewing its formation documents (such as bylaws or other policies or procedures) can also be an important step to determine whether the OPMA to it. The city attorney should ultimately review this documentation to determine if it qualifies as a city council committee subject to the OPMA.
