 (from Ch. 24, par. 8-1-7)Sec. 8-1-7.         (a) Except as provided otherwise in this Section, no  contract shall be made by the corporate authorities, or by  any committee or member thereof, and no expense shall be incurred by any of  the officers or departments of any municipality, whether the object of the  expenditure has been ordered by the corporate authorities or not, unless an  appropriation has been previously made concerning that contract or expense.  Any contract made, or any expense otherwise incurred, in violation of the  provisions of this section shall be null and void as to the municipality,  and no money belonging thereto shall be paid on account thereof. However,  pending the passage of the annual appropriation ordinance for any fiscal  year, the corporate authorities may authorize heads of departments or other  separate agencies of the municipality to make necessary expenditures for  the support thereof upon the basis of the appropriations of the preceding  fiscal year. However, if it is determined by two-thirds vote of the  corporate authorities then holding office at a regularly scheduled meeting  of the corporate authorities that it is expedient and in the best public  interest to begin proceedings for the construction of a needed public work,  then the provisions of this section shall not apply to the extent that the  corporate authorities may employ or contract for professional services  necessary for the planning and financing of such public work.(b) Notwithstanding any provision of this Code to the contrary, the  corporate authorities of any municipality may make contracts for a term  exceeding one year and not exceeding the term of the mayor or president  holding office at the time the contract is executed,  relating to: (1) the employment of a municipal manager, administrator,  engineer, health officer, land planner, finance director, attorney, police  chief or other officer who requires technical training or knowledge; (2)  the employment of outside professional consultants such as engineers,  doctors, land planners, auditors, attorneys or other professional  consultants who require technical training or knowledge; (3) the provision  of data processing equipment and services; or (4) the provision of services  which directly relate to the prevention, identification or eradication of  disease.  In such case the corporate authorities shall include in the  annual appropriation ordinance for each fiscal year, an appropriation of a  sum of money sufficient to pay the amount which, by the terms of the  contract, is to become due and payable during the current fiscal year.(c) This section shall not apply to municipalities operating under special  charters.(d) In order to promote orderly collective bargaining relationships, to  prevent labor strife and to protect the interests of the public and the  health and safety of the citizens of Illinois, this Section shall not apply  to multi-year collective bargaining agreements between public employers and  exclusive representatives governed by the provisions of the Illinois Public  Labor Relations Act.Notwithstanding any provision of this Code to the contrary, the  corporate authorities of any municipality may enter into multi-year  collective bargaining agreements with exclusive representatives under the  provisions of the Illinois Public Labor Relations Act.(e) Notwithstanding any provision of this Code to the contrary, the  corporate  authorities of any municipality may enter into any multi-year contract or  otherwise  associate for any term under the provisions of Section 10 of Article VII of the  Illinois  Constitution or the Intergovernmental Cooperation Act.
