Whenever at least 100 electors of a city with a population of less than 100,000 present a petition to the city clerk of the city asking that an annual tax, not to exceed .06% of the value, as equalized or assessed by the Department of Revenue, be levied each year on all taxable property of the city for the establishment and maintenance of a public hospital, or for the purchase and maintenance of an existing nonsectarian public hospital, within the city, the city clerk shall certify the proposition for submission at an election in accordance with the general election law. The proposition shall be in substantially the following form: "Shall a ....% tax, for establishing and maintaining (or for purchasing and maintaining) a public hospital be levied against the taxable property of the city of ....?" and shall specify the rate of taxation mentioned in the petition. If a majority of all votes cast on the proposition are in favor of the proposition, the tax specified in the notice shall be levied and collected annually in the same manner as are other general taxes in the city, and shall be known as the hospital fund. However, municipalities authorized to levy this tax on July 1, 1967, shall have a rate limit of .06%, or the limit in effect on July 1, 1967, whichever is greater. Thereafter, the city council shall include an appropriation in the annual appropriation ordinance of such sums of money as may be necessary to defray all necessary expenses and liabilities of the hospital. This annual hospital tax shall be in addition to the amount authorized to be levied for general purposes under Section 8-3-1 and shall be exclusive thereof and not included within any limitation of rate or amount for other municipal purposes.
The foregoing limitations upon tax rates may be increased or decreased under the referendum provisions of the General Revenue Law of Illinois.
