Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (a) Whenever the question of incorporation as a city under this Code is submitted for adoption to the electors of any territory, village, incorporated town, or city under special charter, there may be submitted at the same time for adoption or rejection the question of minority representation in the city council. The proposition shall be in the following form:
        Shall minority representation in the city council be
    (b) If a majority of the votes cast on the question at any election are for minority representation in the city council, the members of the city council, except as otherwise provided, thereafter shall be elected as provided in Section 3.1-15-35.
    (c) The city council, at least 30 days before the first day fixed by law for the filing of candidate petitions for the next general municipal election, shall apportion the city by dividing its population, as ascertained by an official publication of any national, state, school, or city census, by any number not less than 2 nor more than 6. The quotient shall be the ratio of representation in the city council. Districts shall be formed of contiguous and compact territory and contain, as near as practicable, an equal number of inhabitants.
    (d) If a majority of the votes cast on the question at any election are against minority representation in the city council, the members of the city council shall be elected as otherwise provided in this Code.
    (e) At any time after the incorporation of a city under this Code, on petition of electors equal in number to one-eighth the number of legal votes cast at the next preceding general municipal election, the city clerk shall certify the question of the adoption or retention of minority representation to the proper election authority for submission to the electors of that city.

65 ILCS 5/3.1-15-35

    (65 ILCS 5/3.1-15-35) (from Ch. 24, par. 3.1-15-35)
    Sec. 3.1-15-35. Alderpersons under minority representation plan. Every district under a minority representation plan shall be entitled to 3 alderpersons. Alderpersons shall hold their offices for 4 years and until their successors have been elected and qualified, except in cities that have adopted a 2 year term under Section 3.1-10-65. There shall be elected in each district as many alderpersons as the district is entitled to. In all of these elections for alderpersons, each elector may cast as many votes as there are alderpersons to be elected in the elector's district, or may distribute his or her votes, or equal parts of the votes, among the candidates as the elector sees fit. The candidate highest in votes is elected if only one alderperson is elected; the candidates highest and next highest in votes are elected if only 2 alderpersons are elected; and the 3 highest candidates in votes are elected when 3 alderpersons are elected. Vacancies shall be filled as provided in Sections 3.1-10-50 and 3.1-10-55 by either interim election or appointment. An appointment to fill a vacancy shall be made within 60 days after the vacancy occurs. The requirement that an appointment be made within 60 days is an exclusive power and function of the State and is a denial and limitation under Article VII, Section 6, subsection (h) of the Illinois Constitution of the power of a home rule municipality to require that an appointment be made within a different period after the vacancy occurs.

This Section does not prohibit a city from voting in favor of a 2 year term for city officers as provided in Section 3.1-10-65. The provisions of the general election law shall govern elections under this Section.
