All bonds issued under the provisions of this Division shall mature within 20 years from their date and bear interest at a rate not to exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, payable annually or semi-annually, and may be sold as the county board may direct at not less than par and accrued interest, and the proceeds derived from the sale thereof shall be used solely and only for the payment of such claims, or the bonds may be exchanged par for par for such claims.
Before or at the time of issuing any such bonds, the county board shall provide by resolution for the collection of a direct annual tax upon all the taxable property within such county sufficient to pay and discharge the principal of any such bonds at maturity, and to pay the interest thereon as it falls due. A certified copy of such resolution shall be filed in the office of the county clerk, as tax extension officer of said county, and he shall extend the tax therein provided for each of the years while any of such bonds are outstanding. Such tax shall be in addition to any and all other county taxes now or hereafter authorized within the Constitutional limitation. Statutory tax limitations applicable to the county shall not apply to the levy of taxes for the payment of interest or principal of any bonds issued under this Division.
With respect to instruments for the payment of money issued under this Section or its predecessor either before, on, or after the effective date of Public Act 86-4, it is and always has been the intention of the General Assembly (i) that the Omnibus Bond Acts are and always have been supplementary grants of power to issue instruments in accordance with the Omnibus Bond Acts, regardless of any provision of this Division or "An Act to authorize counties having a population of not less than 180,000 and not more than 200,000 to issue bonds for the payment of claims", approved May 25, 1953, that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section or its predecessor are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section or its predecessor within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Division or "An Act to authorize counties having a population of not less than 180,000 and not more than 200,000 to issue bonds for the payment of claims", approved May 25, 1953, that may appear to be or to have been more restrictive than those Acts.
