In any municipality with a population of 500,000 or more the corporate authorities may levy a tax annually upon all the taxable property in the municipality at a rate that will produce not to exceed $4,500,000 upon the valuation to be ascertained by the assessment of such property for purposes of taxation for the year in which each such levy is made. This tax, if levied, shall be for the purpose of paying judgments entered against the municipality prior to January 1, 1941, and tort judgments and judgments for damage to or for the taking of private property for public use entered after January 1, 1941. This tax shall be levied and collected in the same manner as the general taxes of the municipality. It shall be known as the judgment tax and shall be in addition to the maximum of all other taxes which the municipality is now, or may be hereafter, authorized by law to levy upon the aggregate valuation of all taxable property within the municipality.
All money received from this tax shall be set apart in a separate fund and shall be used solely for the purpose of paying judgments as provided for in this section. Judgments against the municipality shall be paid out of this fund in the order in which the judgments were obtained. This order of payment shall not apply to judgments of $1000 or less, which judgments may be paid out of said order and in the order in which these judgments of $1000 or less were obtained.
Interest accrued on these judgments shall be paid with the principal thereof. However, the interest accrued to any particular date on all judgments payable out of this fund may be paid ratably at any time without payment of the principal thereof. Warrants issued in anticipation of the judgment tax under the provisions of Sections 8-1-11 and 8-1-12 shall 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.
With respect to instruments for the payment of money issued under this Section either before, on, or after the effective date of this amendatory Act of 1989, 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 Act that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Act that may appear to be or to have been more restrictive than those Acts.
