(1) Based on the investigation conducted under RCW 42.52.420 or 42.52.450, and subject to rules issued by each board, the board or the staff of the appropriate ethics board may issue an order of dismissal based on any of the following findings:

(a) Any violation that may have occurred is not within the jurisdiction of the board;

(b) The complaint is obviously unfounded or frivolous; or

(c) Any violation that may have occurred does not constitute a material violation because it was inadvertent and minor, or has been cured, and, after consideration of all of the circumstances, further proceedings would not serve the purposes of this chapter.

The written notice to the complainant shall include a statement of the complainant's right to appeal to the board under subsection (3) of this section if the dismissal order was issued by staff.

(b) Direct the staff to conduct further investigation; or

(c) Issue a determination that there is reasonable cause to believe that a violation has been or is being committed.
