The corporate authorities of a city specified in this Division 23 may provide that bonds of the city be issued for the purpose of (1) constructing and equipping a hospital building or buildings, (2) purchasing and maintaining an existing nonsectarian public hospital within the city's corporate limits, or of (3) reconstructing, repairing, remodeling, and improving, or of (4) extending and equipping, an existing hospital building or buildings now owned and operated by the city. These bonds shall be authorized by an ordinance and shall mature at such time, not to exceed 20 years from their date of issue, and bear such rate of interest, 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, as the corporate authorities may determine.
The ordinance providing for the issuance of these bonds shall be submitted to the electors of the city at an election conducted in accordance with the general election law. The proposition shall be certified by the municipal clerk and submitted by the proper election authority. If a majority of the votes cast on this proposition are favorable, the bonds shall be issued for the purpose and in the amount specified in the ordinance. Prior to July 1, 1944, however, in the event that aid is to be received from any agency of the Federal Government in the construction of the project for which these bonds are to be issued and a declaration of that fact is set forth in the ordinance providing for the issuance of the bonds, the ordinance shall become effective immediately upon passage, without submission to the electors and notwithstanding any provision in this Code or in any other law to the contrary. The declaration of the corporate authorities that the project is to be paid for either in whole or in part by a grant from a Federal agency, as set forth in the ordinance, is conclusive. These bonds shall be signed by the president and secretary of the hospital board and by the mayor and city clerk, or commissioner of accounts and finance of the city, and shall be payable out of the taxes to be collected for hospital purposes in that city.
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.
