 (from Ch. 46, par. 10-1)Sec. 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.  (Source: P.A. 97-81, eff. 7-5-11.)
