(a) Whenever 100 or more taxpaying electors of any county shall file a petition in the County Court asking that an annual tax on real and personal property be levied for the purpose of capital improvements to or construction of a public county library or a county library service or system and shall specify a rate of taxation not to exceed three mills on the dollar, the question as to whether said tax shall be levied shall be submitted to the qualified electors of such county at a general or special election. Such petition must be filed at least thirty days prior to the election at which it will be submitted to the voters. The ballot shall be in substantially the following form:



FOR a ______ mill tax on real and personal property to be used for capital improvements to or construction of a public county library or county library service or system.



AGAINST a ______ mill tax on real and personal property to be used for capital improvements to or construction of a public county library or county library service or system.



  (b) The voters may authorize the County Court to issue bonds as prescribed by law for capital improvements to or construction of the library and to authorize the pledge of all, or any part of, the tax authorized in Section 1 of this Amendment for the purpose of retiring the bonds. The interest rate on any bonds shall not exceed the rate provided in this Constitution. The ballot submitting the question to the voters shall be in substantially the following form:



For a ______ mill tax on real and personal property within the county, to be pledged to an issue or issues of bonds not to exceed $______, in aggregate principal amount, to finance capital improvements to or construction of the county library or county library service or system, and to authorize the issuance of the bonds on such terms and conditions as shall be approved by the County Court.



Against a ______ mill tax on real and personal property within the county, to be pledged to an issue or issues of bonds not to exceed $______, in aggregate principal amount, to finance capital improvements to or construction of the county library or county library service or system, and to authorize the issuance of the bonds on such terms and conditions as shall be approved by the County Court.



  (c) The maximum rate of any special tax to pay bonded indebtedness, as authorized by paragraph (b) hereof shall be stated on the ballot.



  (d) The special tax for payment of bonded indebtedness authorized in paragraph (b) hereof shall constitute a special fund pledged as security for the payment of such indebtedness. The special tax shall never be extended for any purpose, nor collected for any greater length of time than necessary to retire such bonded indebtedness, except that tax receipts in excess of the amount required to retire the debt according to its terms may, subject to covenants entered into with the holders of the bonds, be pledged as security for the issuance of additional bonds if authorized by the voters. The tax for such additional bonds shall terminate within the time provided for the tax originally imposed. Upon retirement of the bonded indebtedness, any surplus tax collections, which may have accumulated, shall be transferred to the general funds of the county, and shall be used for maintenance of the county library or county library service or system.



  (e) Notwithstanding any other provision of this Amendment, a tax approved by the voters for the purpose of paying the bonded indebtedness shall not be reduced or diminished, nor shall it be used for any other purpose than to pay principal of, premium or interest on, and the reasonable fees of a trustee or paying agent, so long as the bonded indebtedness shall remain outstanding and unpaid.
