Prior to the delivery of and payment for any bonds authorized under this chapter, a three-fourths (¾) majority of the registered voters of such municipality voting at an election on the question of issuing such bonds shall approve of such bond issue; provided, that no such election shall be necessary in connection with the authorization of refunding bonds under this chapter. The governing body of the municipality shall, by resolution, direct the county election commission to hold the election and state the proposition to issue the bonds as it is to appear on the ballots. It shall not be necessary to submit to the voters any question other than the maximum amount of bonds to be issued and the purpose for the bonds, except that, if such bonds are to be secured by an industrial building, its rental or income, other than the industrial building for which the bonds are proposed to be issued, then the question of whether bonds so secured are to be issued shall be submitted to the voters. Upon receipt of the statement of the votes in the election from the county election commission, the governing body of the municipality, at or before its regular meeting, shall again canvass the returns and determine and declare the results of the election. The governing body shall enter upon its minutes the results and returns in the election, and the entry shall, after the delivery of and payment for any bonds voted upon at the election, be conclusive evidence of the result of the election, and no suit, action or other proceeding contesting the validity of such election shall be entertained in any of the courts of this state thereafter.
