10 ILCS 5/13-2
In counties under the township organization the county board shall at its meeting in July in each even-numbered year except in counties containing a population of 3,000,000 inhabitants or over and except when such judges are appointed by election commissioners, select in each election precinct in the county, 5 capable and discreet persons to be judges of election who shall possess the qualifications required by this Act for such judges. Where neither voting machines nor electronic, mechanical or electric voting systems are used, the county board may, for any precinct with respect to which the board considers such action necessary or desirable in view of the number of voters, and shall for general elections for any precinct containing more than 600 registered voters, appoint in addition to the 5 judges of election a team of 5 tally judges. In such precincts the judges of election shall preside over the election during the hours the polls are open, and the tally judges, with the assistance of the holdover judges designated pursuant to Section 13-6.2, shall count the vote after the closing of the polls. The tally judges shall possess the same qualifications and shall be appointed in the same manner and with the same division between political parties as is provided for judges of election.
However, the county board may appoint 3 judges of election to serve in lieu of the 5 judges of election otherwise required by this Section (1) to serve in any emergency referendum, or in any odd-year regular election or in any special primary or special election called for the purpose of filling a vacancy in the office of representative in the United States Congress or to nominate candidates for such purpose or (2) if the county board passes an ordinance to reduce the number of judges of election to 3 for primary elections.
In addition to such precinct judges, the county board shall appoint special panels of 3 judges each, who shall possess the same qualifications and shall be appointed in the same manner and with the same division between political parties as is provided for other judges of election. The number of such panels of judges required shall be determined by regulations of the State Board of Elections, which shall base the required number of special panels on the number of registered voters in the jurisdiction or the number of absentee ballots voted at recent elections or any combination of such factors.
No more than 3 persons of the same political party shall be appointed judges in the same election district or undivided precinct. The election of the judges of election in the various election precincts shall be made in the following manner: The county board shall select and approve 3 of the election judges in each precinct from a certified list furnished by the chair of the County Central Committee of the first leading political party in such election precinct and shall also select and approve 2 judges of election in each election precinct from a certified list furnished by the chair of the County Central Committee of the second leading political party in such election precinct. However, if only 3 judges of election serve in each election precinct, no more than 2 persons of the same political party shall be judges of election in the same election precinct; and which political party is entitled to 2 judges of election and which political party is entitled to one judge of election shall be determined in the same manner as set forth in the next two preceding sentences with regard to 5 election judges in each precinct. The respective County Central Committee chair shall notify the county board by June 1 of each odd-numbered year immediately preceding the annual meeting of the county board whether or not such certified list will be filed by such chair . Such list shall be arranged according to precincts. The chair of each county central committee shall, insofar as possible, list persons who reside within the precinct in which they are to serve as judges. However, he may, in his sole discretion, submit the names of persons who reside outside the precinct but within the county embracing the precinct in which they are to serve. He must, however, submit the names of at least 2 residents of the precinct for each precinct in which his party is to have 3 judges and must submit the name of at least one resident of the precinct for each precinct in which his party is to have 2 judges. Such certified list, if filed, shall be filed with the county clerk not less than 20 days before the annual meeting of the county board. The county board shall acknowledge in writing to each county chair the names of all persons submitted on such certified list and the total number of persons listed thereon. If no such list is filed or the list is incomplete (that is, no names or an insufficient number of names are furnished for certain election precincts), the county board shall make or complete such list from the names contained in the supplemental list provided for in Section 13-1.1. Provided, further, that in any case where a township has been or shall be redistricted, in whole or in part, subsequent to one general election for Governor, and prior to the next, the judges of election to be selected for all new or altered precincts shall be selected in that one of the methods above detailed, which shall be applicable according to the facts and circumstances of the particular case, but the majority of such judges for each such precinct shall be selected from the first leading political party, and the minority judges from the second leading political party. Provided, further, that in counties having a population of 3,000,000 inhabitants or over the selection of judges of election shall be made in the same manner in all respects as in other counties, except that the provisions relating to tally judges are inapplicable to such counties and except that the county board shall meet during the month of January for the purpose of making such selection, each township committeeperson shall assume the responsibilities given to the chair of the county central committee in this Section for the precincts within his or her township, and the township committeeperson shall notify the county board by the preceding October 1 whether or not the certified list will be filed. Such judges of election shall hold their office for 2 years from their appointment and until their successors are duly appointed in the manner provided in this Act. The county board shall fill all vacancies in the office of judges of elections at any time in the manner herein provided.
Such selections under this Section shall be confirmed by the circuit court as provided in Section 13-3 of this Article.
