(820 ILCS 130/9) (from Ch. 48, par. 39s-9)
    Sec. 9. To effectuate the purpose and policy of this Act each public body shall, during the month of June of each calendar year, investigate and ascertain the prevailing rate of wages as defined in this Act and publicly post or keep available for inspection by any interested party in the main office of such public body its determination of such prevailing rate of wage and shall promptly file, no later than July 15 of each year, a certified copy thereof in the office of the Illinois Department of Labor.
    The Department of Labor shall during the month of June of each calendar year, investigate and ascertain the prevailing rate of wages for each county in the State. If a public body does not investigate and ascertain the prevailing rate of wages during the month of June as required by the previous paragraph, then the prevailing rate of wages for that public body shall be the rate as determined by the Department under this paragraph for the county in which such public body is located. The Department shall publish on its official website a prevailing wage schedule for each county in the State, no later than August 15 of each year, based on the prevailing rate of wages investigated and ascertained by the Department during the month of June. Nothing prohibits the Department from publishing prevailing wage rates more than once per year.
    Where the Department of Labor ascertains the prevailing rate of wages, it is the duty of the Department of Labor within 30 days after receiving a notice from the public body authorizing the proposed work, to conduct an investigation to ascertain the prevailing rate of wages as defined in this Act and such investigation shall be conducted in the locality in which the work is to be performed. The Department of Labor shall send a certified copy of its findings to the public body authorizing the work and keep a record of its findings available for inspection by any interested party in the office of the Department of Labor at Springfield.
    The public body except for the Department of Transportation with respect to highway contracts shall within 30 days after filing with the Department of Labor, or the Department of Labor shall within 30 days after filing with such public body, publish in a newspaper of general circulation within the area that the determination is effective, a notice of its determination and shall promptly mail a copy of its determination to any employer, and to any association of employers and to any person or association of employees who have filed their names and addresses, requesting copies of any determination stating the particular rates and the particular class of workers whose wages will be affected by such rates. If the Department of Labor ascertains the prevailing rate of wages for a public body, the public body may satisfy the newspaper publication requirement in this paragraph by posting on the public body's website a notice of its determination with a hyperlink to the prevailing wage schedule for that locality that is published on the official website of the Department of Labor.
    At any time within 30 days after the Department of Labor has published on its official web site a prevailing wage schedule, any person affected thereby may object in writing to the determination or such part thereof as they may deem objectionable by filing a written notice with the public body or Department of Labor, whichever has made such determination, stating the specified grounds of the objection. It shall thereafter be the duty of the public body or Department of Labor to set a date for a hearing on the objection after giving written notice to the objectors at least 10 days before the date of the hearing and said notice shall state the time and place of such hearing. Such hearing by a public body shall be held within 45 days after the objection is filed, and shall not be postponed or reset for a later date except upon the consent, in writing, of all the objectors and the public body. If such hearing is not held by the public body within the time herein specified, the Department of Labor may, upon request of the objectors, conduct the hearing on behalf of the public body.
    The public body or Department of Labor, whichever has made such determination, is authorized in its discretion to hear each written objection filed separately or consolidate for hearing any one or more written objections filed with them. At such hearing, the public body or Department of Labor shall introduce in evidence the investigation it instituted which formed the basis of its determination, and the public body or Department of Labor, or any interested objectors may thereafter introduce such evidence as is material to the issue. Thereafter, the public body or Department of Labor, must rule upon the written objection and make such final determination as it believes the evidence warrants, and promptly file a certified copy of its final determination with such public body, and serve a copy by personal service or registered mail on all parties to the proceedings. The final determination by the Department of Labor or a public body shall be rendered within 30 days after the conclusion of the hearing.
    If proceedings to review judicially the final determination of the public body or Department of Labor are not instituted as hereafter provided, such determination shall be final and binding.
    The provisions of the Administrative Review Law, and all amendments and modifications thereof, and the rules adopted pursuant thereto, shall apply to and govern all proceedings for the judicial review of final administrative decisions of any public body or the Department of Labor hereunder. The term "administrative decision" is defined as in Section 3-101 of the Code of Civil Procedure.
    Appeals from all final orders and judgments entered by the court in review of the final administrative decision of the public body or Department of Labor, may be taken by any party to the action.
    Any proceeding in any court affecting a determination of the Department of Labor or public body shall have priority in hearing and determination over all other civil proceedings pending in said court, except election contests.
    In all reviews or appeals under this Act, it shall be the duty of the Attorney General to represent the Department of Labor, and defend its determination. The Attorney General shall not represent any public body, except the State, in any such review or appeal.
