The OPMA addresses the public’s right to observe, not to participate, in a public meeting. However, a member of the public shall not be required, as a condition to attend a meeting, to register his or her name and other information, to complete a questionnaire, or otherwise to fulfill any condition precedent to attendance. RCW 42.30.040.

There is no right to participate, unless the agency has adopted rules requiring or permitting such participation. 

If a meeting is interrupted by a person or a group so as to render the orderly conduct of the meeting unfeasible and order cannot be restored by the removal of individuals who are interrupting the meeting, the members of the governing body conducting the meeting may order the meeting room cleared and continue in session or may adjourn the meeting and reconvene at another location selected by a majority vote of the members. RCW 42.30.050. However, representatives of the press or other news media, except those participating in the disturbance, shall not be removed and may attend any session held after members of the public have been excluded due to disruption.
