65 ILCS 5/11-51-1
Whenever any cemetery is embraced within the limits of any city, village, or incorporated town, the corporate authorities thereof, if, in their opinion, any good cause exists why such cemetery should be removed, may cause the remains of all persons interred therein to be removed to some other suitable place. However, the corporate authorities shall first obtain the assent of the trustees or other persons having the control or ownership of such cemetery, or a majority thereof. When such cemetery is owned by one or more private parties, or private corporation or chartered society, the corporate authorities of such city may require the removal of such cemetery to be done at the expense of such private parties, or private corporation or chartered society, if such removal be based upon their application. Nothing in this Section limits the powers of the City of Chicago to acquire property or otherwise exercise its powers under Section 15 of the O'Hare Modernization Act.
