(1) The governing authority of any political subdivision may, without an election on the question of the issuance thereof, issue the bonds of such subdivision for the purpose of refunding any bonded indebtedness of such subdivision now or hereafter outstanding, whether such bonded indebtedness shall at the time of such refunding be due or to mature in the future, and regardless of whether the issuance of such refunding bonds shall create a total bonded indebtedness of such subdivision in excess of the then existing statutory limitation of debt.

(2) The board of supervisors of any county may issue the bonds of any county, consolidated school district, rural separate school district or separate road district, for the purpose of refunding the outstanding bonded indebtedness of any such county or district when the same shall mature, whether now due or to become due in the future without notice and without an election on the question of the issuance of same, regardless of whether or not the issuance of such bonds shall create a total bonded indebtedness in excess of the then existing statutory limitation of debt.

(3) Such bonds may be issued in sufficient amount to pay and retire any of the then outstanding bonds, whether matured or to mature in the future, together with interest thereon to the date of the refunding bonds or to such prior date as the governing authority may determine; and such power to refund such bonds and interest may be exercised whenever funds available from taxes are not sufficient to pay such outstanding bonds and the interest thereon whenever they may mature.
