(1) Any aggrieved party may request an administrative review of the initial determination. If the secretary does not receive a request, in writing, for an administrative review within twenty-one days of service of the initial determination then the initial determination automatically becomes a final determination. If the parties have not requested an administrative review, the secretary may review the presiding officer's adjudication on his or her own motion as provided by RCW 34.05.491.

(2) The reviewing officer may be the secretary, the assistant or deputy secretary, or the director of elections, except that the same person may not serve as both the presiding officer and reviewing officer. The reviewing officer shall give each party an opportunity to explain the party's view of the matter, but must render a final determination within ninety days after the original filing of the complaint unless the complainant consents to a longer period. The determination of the reviewing officer is final and no further administrative review is available. The final determination shall include notice that judicial review may be available.
