In all cases where any county having a population of 500,000 or more inhabitants has incurred indebtedness prior to August 7, 1947 for proper county purposes, such indebtedness being evidenced by judgments rendered prior to August 7, 1947 against such county, such county may issue negotiable coupon bonds in such an amount not exceeding $3,000,000 as is necessary for the purpose of paying same, and may levy taxes upon all the taxable property in such county sufficient to pay the principal of such bonds at maturity and to pay the interest thereon, as it falls due, within the constitutional limitation of 75 cents per $100 of valuation, without submitting the question of issuing such bonds and levying such taxes to a vote of the people of such county. Such bonds shall bear interest at a rate of not to exceed five per centum per annum and the maturity thereof shall be determined by the county board within twenty years from their date and such bonds shall be authorized by resolution adopted by the county board prescribing all details of issue and determining the amount of unpaid indebtedness incurred for proper county purposes evidenced by judgments, which finding shall be conclusive as to the amount and validity thereof.
Such bonds shall be sold for not less than their par value upon sealed bids. The County Board shall from time to time as bonds are to be sold, advertise in a daily newspaper of general circulation of such county for proposals to purchase such bonds, at least ten days prior to the opening of the bids. The County Board may reserve the right to reject any and all bids. The judgments shall be satisfied and released simultaneously upon the delivery of the bonds, and proper records shall be made showing such payment and satisfaction thereof. Such payments may be made without any prior appropriation therefor under any budget law.
Such bonds and coupons shall be payable in lawful money of the United States of America at such place or places as may be fixed in the resolution authorizing same and shall be signed in the manner and by the officials directed by such resolution and such bonds may be issued in an amount, including existing indebtedness, not to exceed the constitutional limitation as to debt notwithstanding any statutory debt limitation to the contrary.
The validity of any bonds hereby authorized to be issued shall remain unimpaired although one or more of the officials executing such bonds shall cease to be such officer or officers before the date of delivery thereof.
