Illinois Statutes Chapter 65. Municipalities § 5/7-1-15. Annexation of adjoining municipality by ordinance; referendum

(1) the annexation provided in these ordinances is certified by the clerk to the proper election authority who shall submit the question to a vote of the electors of both municipalities at an election in accordance with the general election law; and if

(2) the annexation is approved in each municipality by a majority of all the voters voting on that question in each municipality. If the ordinances fail to specify the terms of annexation or specify only partially the terms of annexation, the provisions of this article relating to the annexation of one municipality to another shall apply but not as to any terms agreed to in the ordinances of annexation.

The proposition shall be in substantially the following form:

Annexation shall neither affect nor impair any rights or liabilities either in favor of or against either municipality. Actions founded upon any right or liability may be commenced despite the annexation and, together with pending actions, may be prosecuted to final judgment and the enforcement thereof as if annexation had not taken place.
