(70 ILCS 1005/13) (from Ch. 111 1/2, par. 85a)
    Sec. 13. The owner or owners of record of any area of land consisting of one or more tracts lying within the corporate limits of any mosquito abatement district may have the area disconnected from the mosquito abatement district in the following manner:
    The owner or owners of record of any such tract or tracts of land shall file a petition in the Circuit Court of the county in which the district was organized alleging facts in support of disconnection, including the following:
    (1) That the tract or tracts involved are located upon the border of the district;
    (2) That disconnection will not result in the isolation of any part of the district from the remainder of the district;
    (3) That disconnection will not destroy, or impair the effectiveness of the mosquito abatement district in the performance of its lawful functions of controlling and exterminating mosquitoes, flies and other insects within the district;
    (4) That disconnection will not jeopardize the financial position of the district;
    (5) And that disconnection will not adversely affect the public health and welfare.
    The mosquito abatement district from which disconnection is sought shall be made a defendant, and it or any taxpayer residing in the district may appear and defend against the petition.
    The court shall set the petition for hearing on a date not less than 30 days after the filing of the petition, and copy of the petition shall be mailed to the Department of Public Health of the State of Illinois and to the Illinois State Natural History Survey by the clerk of the court, such copies to be furnished by the petitioners. The court shall not proceed to final hearing of the petition without a joint written report from the Department of Public Health and the Illinois State Natural History Survey as to the probable effect upon the public health and welfare and upon the effectiveness of the mosquito abatement district in the performance of its lawful duties if disconnection were granted as prayed. A copy of such report shall also be mailed to the petitioners or their attorneys of record. The court shall upon request grant to any party the right to examine witnesses from such state agencies as may have investigated the facts incorporated in any such reports.
    If the court finds that the allegations of the petition are true and that the area of land is entitled to disconnection, it shall order the specified land disconnected from the mosquito abatement district and thereupon said land shall cease to be a part of such district. Said land shall not, however, be relieved from any bonded indebtedness of the district previously created as to its proportionate share thereof.
    The decision of the court is appealable as in other civil cases.
    The provisions of this section 13 shall not apply to districts incorporated in counties of over 500,000 population.
