(65 ILCS 5/7-1-48) (from Ch. 24, par. 7-1-48)
    Sec. 7-1-48. For all annexations under this Article 7: (a) Except as may be otherwise expressly restricted, territory comprising more than one parcel of record, or more than one unsubdivided parcel, or more than one portion of a parcel, or owned by more than one owner of record, or any combination of the foregoing, may be annexed in a single annexation proceeding;
    (b) If any annexation shall not be in compliance with applicable requirements of this Article 7, and if such non-compliance relates only to one or more parcels or portions of the territory annexed or to be annexed, but does not relate to the entire annexation proceeding or to a substantial portion of the total area annexed, such annexation shall nonetheless be valid as to the remainder of the annexed territory, unless the exclusion or disconnection of the non-complying area would destroy the contiguity of any of the remaining territory;
    (c) In any proper proceeding, upon a judicial determination of partial invalidity of an annexation which has otherwise been completed, the court may, as equity may require, order the disconnection of the invalidly annexed parcels or portions, in which event the municipality shall promptly prepare and record a plat of disconnection of such area with the recorder of the county in which the land is situated, and shall immediately notify the county clerk of such disconnection.
