If three-fifths of the votes cast at any election under the provisions of RCW 87.52.010 through 87.52.060 shall contain the words "Disorganize, Yes," then the board of directors shall present to the superior judge of the county in which said irrigation district is located an application for an order of said superior court that such irrigation district be declared disorganized and dissolved, and that its affairs be liquidated and wound up, as provided for in RCW 87.52.010 through 87.52.060, and reciting that at an election of such irrigation district, held as provided in RCW 87.52.010 through 87.52.060, three-fifths of the votes cast contained the words "Disorganize, Yes," and such petition shall be certified to by the directors of said district. They shall also file with said superior court a statement, sworn to by the directors of said irrigation district, showing all outstanding indebtedness of said irrigation district, or if there be no such indebtedness, then the directors shall make oath to that effect. Notice of said application shall be given by the clerk, which notice shall set forth the nature of the application, and shall specify the time and place at which it is to be heard, and shall be published in a newspaper of the county printed and published nearest to said irrigation district, once each week for four weeks, or if no newspaper is published in the county, by publication in the newspaper nearest thereto in the state.
