Any taxpayer feeling aggrieved by the levy or levies of any taxing district except levies authorized by a vote of the voters of the district may appeal therefrom to the department of revenue as hereinafter provided. Such taxpayer, upon the execution of a bond, with two or more sufficient sureties to be approved by the county auditor, payable to the state of Washington, in the penal sum of two hundred dollars and conditioned that if the petitioner shall fail in his or her appeal for a reduction of said levy or levies the taxpayer will pay the taxable costs of the hearings hereinafter provided, not exceeding the amount of such bond, may file a written complaint with the county auditor wherein such taxing district is located not later than ten days after the making and entering of such levy or levies, setting forth in such form and detail as the department of revenue shall by general rule prescribe, the taxpayer's objections to such levy or levies. Upon the filing of such complaint, the county auditor shall immediately transmit a certified copy thereof, together with a copy of the budget or estimates of such taxing district as finally adopted, including estimated revenues and such other information as the department of revenue shall by rule require, to the department of revenue. The department of revenue shall fix a date for a hearing on said complaint at the earliest convenient time after receipt of said record, which hearing shall be held in the county in which said taxing district is located, and notice of such hearing shall be given to the officials of such taxing district, charged with determining the amount of its levies, and to the taxpayer on said complaint by registered mail at least five days prior to the date of said hearing. At such hearings all interested parties may be heard and the department of revenue shall receive all competent evidence. After such hearing, the department of revenue shall either affirm or decrease the levy or levies complained of, in accordance with the evidence, and shall thereupon certify its action with respect thereto to the county auditor, who, in turn, shall certify it to the taxing district or districts affected, and the action of the department of revenue with respect to such levy or levies shall be final and conclusive.
