The governing body of any municipality desiring to enter into the plan authorized in this chapter, after receiving a certificate of public purpose and necessity from the committee, as provided by this chapter, by resolutions spread upon its minutes, shall declare its intention of entering into such plan, and prior to the delivery and payment for any bonds authorized under this chapter a three-fourths (3/4) majority of the registered voters of such municipality voting at an election on the special 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 shall, by resolution, direct the county election commission to hold an election on the question of issuing the bonds. 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. It is the duty of the governing body of such municipality to enter upon its minutes the results and returns of such election, and, after the delivery of any bonds voted upon at such election and payment for the bonds, such entry upon its minutes shall be conclusive evidence of the result of such election, and no suit, action or other proceeding contesting the validity of such election shall be entertained in any of the courts of the state thereafter. If such election results unfavorably to the proposition, then no second or other election shall be ordered or held until the committee shall determine that such election may be held.
