Illinois Statutes § 5/10-1 Application of Article to minor political parties

(a) Political parties as defined in this Article and individual voters to the number and in the manner specified in this Article may nominate candidates for public offices whose names shall be placed on the ballot to be furnished, as provided in this Article. No nominations may be made under this Article 10, however, by any established political party which, at the general election next preceding, polled more than 5% of the entire vote cast in the State, district, or unit of local government for which the nomination is made. Those nominations provided for in Section 45-5 of the Township Code shall be made as prescribed in Sections 45-10 through 45-45 of that Code for nominations by established political parties, but minor political parties and individual voters are governed by this Article. Any convention, caucus, or meeting of qualified voters of any established political party as defined in this Article may, however, make one nomination for each office therein to be filled at any election for officers of a municipality with a population of less than 5,000 by causing a certificate of nomination to be filed with the municipal clerk no earlier than 113 and no later than 106 days before the election at which the nominated candidates are to be on the ballot. The municipal caucuses shall be conducted on the first Monday in December of even-numbered years , except that, when that Monday is a holiday or the eve of a holiday, the caucuses shall be held on the next business day following the holiday. Every certificate of nomination shall state the facts required in Section 10-5 of this Article and shall be signed by the presiding officer and by the secretary of the convention, caucus, or meeting, who shall add to their signatures their places of residence. The certificates shall be sworn to by them to be true to the best of their knowledge and belief, and a certificate of the oath shall be annexed to the certificate of nomination.

(b) Publication of the time and place of holding the caucus shall be given by the municipal clerk. For municipalities of over 500 population, notice of the caucus shall be published in a newspaper published in the municipality. If there is no such newspaper, then the notice shall be published in a newspaper published in the county and having general circulation in the municipality. For municipalities of 500 population or less, notice of the caucus shall be given by the municipal clerk by posting the notice in 3 of the most public places in the municipality. The publication or posting shall be given at least 10 days before the caucus.

(c) As provided in Sections 3.1-25-20 through 3.1-25-60 of the Illinois Municipal Code, a village may adopt a system of nonpartisan primary and general elections for the election of village officers.

(d) Any city, village, or incorporated town with a population of 5,000 or less may, by ordinance, determine that established political parties shall nominate candidates for municipal office in the city, village, or incorporated town by primary in accordance with Article 7.

(e) Only those voters who reside within the territory for which the nomination is made shall be permitted to vote or take part in the proceedings of any convention, caucus, or meeting of individual voters or of any political party held under this Section. No voter shall vote or take part in the proceedings of more than one convention, caucus, or meeting to make a nomination for the same office.
