In case any Hospital District organized hereunder shall be coterminous with or shall include within its corporate limits in whole or in part any pre-existing public agency authorized to own, operate and maintain a public hospital and to levy taxes for any such purpose, then such public agency shall cease to exercise any power in respect to hospitals within such Hospital District from and after the date that it receives written notice from the Director of Public Health to cease operation of its hospital, which notice shall be given only after the Director of Public Health has ascertained that the Hospital District has placed its hospital facilities in operation, and such public agency shall not thereafter own, operate, maintain, manage, control or have an interest in any public hospital within the corporate limits of said Hospital District. The Director of Public Health, upon request of the Board of Directors of any Hospital District, shall ascertain whether its hospital facilities are in operation so that it may supersede the power of any public agency to operate a hospital within the boundaries of the District. Where in any case any pre-existing public agency is in fact owning, operating and maintaining a public hospital located within the corporate limits of a Hospital District organized under this Act, such public agency shall be paid and reimbursed, upon such terms as may be agreed upon by its corporate authorities and the Board of Directors of such Hospital District, its actual expenditures theretofore made in acquiring the land for any such hospital and in acquiring, constructing, improving or developing any existing hospital facilities, not including funds advanced for that purpose or otherwise paid or expended either directly or indirectly by State or Federal governments. The terms of payment shall provide for reimbursement in full within not less than twenty years from the date of such agreement.
     In case the amount and terms of reimbursement cannot be determined or agreed upon between the corporate authorities of any existing public agency and the Board of Directors of the Hospital District, the Board of Directors of such Hospital District shall cause a description of the existing hospital facilities to be made, together with an estimate of all actual expenditures made by the public agency therefor and shall tender payment of the total amount so estimated in writing to the corporate authorities of such public agency. Such tender shall provide for payment by the District of the amount tendered within ten years from date thereof, and that portion of said sum to be paid on and after twelve months from the date of such tender 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. In case such a tender is not accepted in writing by the corporate authorities of such public agency within thirty days after the same is made, the Hospital District by its Board of Directors shall file a petition in the Circuit Court of the county in which the Hospital District and such public agency or the major portions thereof are situated, making such public agency a party defendant thereto, setting forth a description of the hospital facilities, the estimated amount of expenditures made by the defendants thereon, the fact that a tender had been made for the payment of the actual expenditures in accordance with the estimate, and praying that it be determined by the Circuit Court the true amount of such expenditures by said public agency. A copy of such petition shall be served upon the presiding officer of such public agency within five days after filing of the petition and upon presentation to the court of proof of such service said petition shall be set down for hearing within not more than sixty days from the date of filing said petition. The hearing thereon may be continued from time to time upon the request of either party within the discretion of the Circuit Court and upon the hearing the Circuit Court shall consider such evidence as may be submitted by either party and shall determine the amount of such actual expenditures made by the public agency for the existing hospital facilities. The amount so determined shall be conclusive as between said parties and shall be paid by the Hospital District within five years after the entry of the order by the Circuit Court and that portion of the amount which is not to be paid within twelve months from date of the order 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, and the public agency shall accept said sums in full payment for all existing hospital facilities owned by it and said public agency shall from and after the entry of the order of the Circuit Court and receipt of notice from the Director of Public Health cease to exercise any power in respect to public hospitals within the corporate limits of the said Hospital District.
     Any money received by a public agency pursuant to this section shall be used to discharge any debt resulting from the construction, operation or maintenance of its public hospital, and the balance shall be used for its general corporate purposes.
     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.
