Illinois Compiled Statutes

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.

ELECTIONS
(10 ILCS 5/) Election Code.

10 ILCS 5/24C-11

    (10 ILCS 5/24C-11)
    Sec. 24C-11. Functional requirements. A Direct Recording Electronic Voting System shall, in addition to satisfying the other requirements of this Article, fulfill the following functional requirements:
    (a) Provide a voter in a primary election with the means of casting a ballot containing votes for any and all candidates of the party or parties of his or her choice, and for any and all non-partisan candidates and public questions and preclude the voter from voting for any candidate of any other political party except when legally permitted. In a general election, the system shall provide the voter with means of selecting the appropriate number of candidates for any office, and of voting on any public question on the ballot to which he or she is entitled to vote.
    (b) If a voter is not entitled to vote for particular candidates or public questions appearing on the ballot, the system shall prevent the selection of the prohibited votes.
    (c) Once the proper ballot has been selected, the system devices shall provide a means of enabling the recording of votes and the casting of said ballot.
    (d) System voting devices shall provide voting choices that are clear to the voter and labels indicating the names of every candidate and the text of every public question on the voter's ballot. Each label shall identify the selection button or switch, or the active area of the ballot associated with it. The system shall be able to incorporate minimal, easy-to-follow on-screen instruction for the voter on how to cast a ballot.
    (e) Voting devices shall (i) enable the voter to vote for any and all candidates and public questions appearing on the ballot for which the voter is lawfully entitled to vote, in any legal number and combination; (ii) detect and reject all votes for an office or upon a public question when the voter has cast more votes for the office or upon the public question than the voter is entitled to cast; (iii) notify the voter if the voter's choices as recorded on the ballot for an office or public question are fewer than or exceed the number that the voter is entitled to vote for on that office or public question and the effect of casting more or fewer votes than legally permitted; (iv) notify the voter if the voter has failed to completely cast a vote for an office or public question appearing on the ballot; and (v) permit the voter, in a private and independent manner, to verify the votes selected by the voter, to change the ballot or to correct any error on the ballot before the ballot is completely cast and counted. A means shall be provided to indicate each selection after it has been made or canceled.
    (f) System voting devices shall provide a means for the voter to signify that the selection of candidates and public questions has been completed. Upon activation, the system shall record an image of the completed ballot, increment the proper ballot position registers, and shall signify to the voter that the ballot has been cast. The system shall then prevent any further attempt to vote until it has been reset or re-enabled by a judge of election.
    (g) Each system voting device shall be equipped with a public counter that can be set to zero prior to the opening of the polling place, and that records the number of ballots cast at a particular election. The counter shall be incremented only by the casting of a ballot. The counter shall be designed to prevent disabling or resetting by other than authorized persons after the polls close. The counter shall be visible to all judges of election so long as the device is installed at the polling place.
    (h) Each system voting device shall be equipped with a protective counter that records all of the testing and election ballots cast since the unit was built. This counter shall be designed so that its reading cannot be changed by any cause other than the casting of a ballot. The protective counter shall be incapable of ever being reset and it shall be visible at all times when the device is configured for testing, maintenance, or election use.
    (i) All system devices shall provide a means of preventing further voting once the polling place has closed and after all eligible voters have voted. Such means of control shall incorporate a visible indication of system status. Each device shall prevent any unauthorized use, prevent tampering with ballot labels and preclude its re-opening once the poll closing has been completed for that election.
    (j) The system shall produce a printed summary report of the votes cast upon each voting device. Until the proper sequence of events associated with closing the polling place has been completed, the system shall not allow the printing of a report or the extraction of data. The printed report shall also contain all system audit information to be required by the election authority. Data shall not be altered or otherwise destroyed by report generation and the system shall ensure the integrity and security of data for a period of at least 6 months after the polls close.
    (k) If more than one voting device is used in a polling place, the system shall provide a means to manually or electronically consolidate the data from all such units into a single report even if different voting systems are used to record ballots. The system shall also be capable of merging the vote tabulation results produced by other vote tabulation systems, if necessary.
    (l) System functions shall be implemented such that unauthorized access to them is prevented and the execution of authorized functions in an improper sequence is precluded. System functions shall be executable only in the intended manner and order, and only under the intended conditions. If the preconditions to a system function have not been met, the function shall be precluded from executing by the system's control logic.
    (m) All system voting devices shall incorporate at least 3 memories in the machine itself and in its programmable memory devices.
    (n) The system shall include capabilities of recording and reporting the date and time of normal and abnormal events and of maintaining a permanent record of audit information that cannot be turned off. Provisions shall be made to detect and record significant events (e.g., casting a ballot, error conditions that cannot be disposed of by the system itself, time-dependent or programmed events that occur without the intervention of the voter or a judge of election).
    (o) The system and each system voting device must be capable of creating, printing and maintaining a permanent paper record and an electronic image of each ballot that is cast such that records of individual ballots are maintained by a subsystem independent and distinct from the main vote detection, interpretation, processing and reporting path. The electronic images of each ballot must protect the integrity of the data and the anonymity of each voter, for example, by means of storage location scrambling. The ballot image records may be either machine-readable or manually transcribed, or both, at the discretion of the election authority.
    (p) The system shall include built-in test, measurement and diagnostic software and hardware for detecting and reporting the system's status and degree of operability.
    (q) The system shall contain provisions for maintaining the integrity of memory voting and audit data during an election and for a period of at least 6 months thereafter and shall provide the means for creating an audit trail.
    (r) The system shall be fully accessible so as to permit blind or visually impaired voters as well as voters with physical disabilities to exercise their right to vote in private and without assistance.
    (s) The system shall provide alternative language accessibility if required pursuant to Section 203 of the Voting Rights Act of 1965.
    (t) Each voting device shall enable a voter to vote for a person whose name does not appear on the ballot.
    (u) The system shall record and count accurately each vote properly cast for or against any candidate and for or against any public question, including the names of all candidates whose names are written in by the voters.
    (v) The system shall allow for accepting provisional ballots and for separating such provisional ballots from precinct totals until authorized by the election authority.
    (w) The system shall provide an effective audit trail as defined in Section 24C-2 in this Code.
    (x) The system shall be suitably designed for the purpose used, be durably constructed, and be designed for safety, accuracy and efficiency.
    (y) The system shall comply with all provisions of federal, State and local election laws and regulations and any future modifications to those laws and regulations.

10 ILCS 5/24C-12

    (10 ILCS 5/24C-12)
    Sec. 24C-12. Procedures for counting and tallying of ballots. In an election jurisdiction where a Direct Recording Electronic Voting System is used, the following procedures for counting and tallying the ballots shall apply:
    Before the opening of the polls, the judges of elections shall assemble the voting equipment and devices and turn the equipment on. The judges shall, if necessary, take steps to activate the voting devices and counting equipment by inserting into the equipment and voting devices appropriate data cards containing passwords and data codes that will select the proper ballot formats selected for that polling place and that will prevent inadvertent or unauthorized activation of the poll-opening function. Before voting begins and before ballots are entered into the voting devices, the judges of election shall cause to be printed a record of the following: the election's identification data, the device's unit identification, the ballot's format identification, the contents of each active candidate register by office and of each active public question register showing that they contain all zero votes, all ballot fields that can be used to invoke special voting options, and other information needed to ensure the readiness of the equipment and to accommodate administrative reporting requirements. The judges must also check to be sure that the totals are all zeros in the counting columns and in the public counter affixed to the voting devices.
    After the judges have determined that a person is qualified to vote, a voting device with the proper ballot to which the voter is entitled shall be enabled to be used by the voter. The ballot may then be cast by the voter by marking by appropriate means the designated area of the ballot for the casting of a vote for any candidate or for or against any public question. The voter shall be able to vote for any and all candidates and public measures appearing on the ballot in any legal number and combination and the voter shall be able to delete, change or correct his or her selections before the ballot is cast. The voter shall be able to select candidates whose names do not appear upon the ballot for any office by entering electronically as many names of candidates as the voter is entitled to select for each office.
    Upon completing his or her selection of candidates or public questions, the voter shall signify that voting has been completed by activating the appropriate button, switch or active area of the ballot screen associated with end of voting. Upon activation, the voting system shall record an image of the completed ballot, increment the proper ballot position registers, and shall signify to the voter that the ballot has been cast. Upon activation, the voting system shall also print a permanent paper record of each ballot cast as defined in Section 24C-2 of this Code. This permanent paper record shall (i) be printed in a clear, readily readable format that can be easily reviewed by the voter for completeness and accuracy and (ii) either be self-contained within the voting device or be deposited by the voter into a secure ballot box. No permanent paper record shall be removed from the polling place except by election officials as authorized by this Article. All permanent paper records shall be preserved and secured by election officials in the same manner as paper ballots and shall be available as an official record for any recount, redundant count, or verification or retabulation of the vote count conducted with respect to any election in which the voting system is used. The voter shall exit the voting station and the voting system shall prevent any further attempt to vote until it has been properly re-activated. If a voting device has been enabled for voting but the voter leaves the polling place without casting a ballot, 2 judges of election, one from each of the 2 major political parties, shall spoil the ballot.
    Throughout the election day and before the closing of the polls, no person may check any vote totals for any candidate or public question on the voting or counting equipment. Such equipment shall be programmed so that no person may reset the equipment for reentry of ballots unless provided the proper code from an authorized representative of the election authority.
    The precinct judges of election shall check the public register to determine whether the number of ballots counted by the voting equipment agrees with the number of voters voting as shown by the applications for ballot. If the same do not agree, the judges of election shall immediately contact the offices of the election authority in charge of the election for further instructions. If the number of ballots counted by the voting equipment agrees with the number of voters voting as shown by the application for ballot, the number shall be listed on the "Statement of Ballots" form provided by the election authority.
    The totals for all candidates and propositions shall be tabulated. One copy of an "In-Precinct Totals Report" shall be generated by the automatic tabulating equipment for return to the election authority. One copy of an "In-Precinct Totals Report" shall be generated and posted in a conspicuous place inside the polling place, provided that any authorized pollwatcher or other official authorized to be present in the polling place to observe the counting of ballots is present. The judges of election shall provide, if requested, a set for each authorized pollwatcher or other official authorized to be present in the polling place to observe the counting of ballots. In addition, sufficient time shall be provided by the judges of election to the pollwatchers to allow them to copy information from the copy which has been posted.
    Until December 31, 2019, in elections at which fractional cumulative votes are cast for candidates, the tabulation of those fractional cumulative votes may be made by the election authority at its central office location, and 4 copies of a "Certificate of Results" shall be printed by the automatic tabulation equipment and shall be posted in 4 conspicuous places at the central office location where those fractional cumulative votes have been tabulated.
    If instructed by the election authority, the judges of election shall cause the tabulated returns to be transmitted electronically to the offices of the election authority via modem or other electronic medium.
    The precinct judges of election shall select a bi-partisan team of 2 judges, who shall immediately return the ballots in a sealed container, along with all other election materials and equipment as instructed by the election authority; provided, however, that such container must first be sealed by the election judges with filament tape or other approved sealing devices provided for the purpose in a manner that the ballots cannot be removed from the container without breaking the seal or filament tape and disturbing any signatures affixed by the election judges to the container. The election authority shall keep the office of the election authority, or any receiving stations designated by the authority, open for at least 12 consecutive hours after the polls close or until the ballots and election material and equipment from all precincts within the jurisdiction of the election authority have been returned to the election authority. Ballots and election materials and equipment returned to the office of the election authority which are not signed and sealed as required by law shall not be accepted by the election authority until the judges returning the ballots make and sign the necessary corrections. Upon acceptance of the ballots and election materials and equipment by the election authority, the judges returning the ballots shall take a receipt signed by the election authority and stamped with the time and date of the return. The election judges whose duty it is to return any ballots and election materials and equipment as provided shall, in the event the ballots, materials or equipment cannot be found when needed, on proper request, produce the receipt which they are to take as above provided.

    (10 ILCS 5/24C-13)
    Sec. 24C-13. Vote by mail ballots; early voting ballots; proceedings at location for central counting; employees; approval of list.
    (a) All jurisdictions using Direct Recording Electronic Voting Systems shall use paper ballots or paper ballot sheets approved for use under Articles 16, 24A or 24B of this Code when conducting vote by mail voting. All vote by mail ballots shall be counted at the central ballot counting location of the election authority. The provisions of Section 24A-9, 24B-9 and 24C-9 of this Code shall apply to the testing and notice requirements for central count tabulation equipment, including comparing the signature on the ballot envelope with the signature of the voter on the permanent voter registration record card taken from the master file. Vote results shall be recorded by precinct and shall be added to the vote results for the precinct in which the vote by mail voter was eligible to vote prior to completion of the official canvass.
    (b) All proceedings at the location for central counting shall be under the direction of the county clerk or board of election commissioners. Except for any specially trained technicians required for the operation of the Direct Recording Electronic Voting System, the employees at the counting station shall be equally divided between members of the 2 leading political parties and all duties performed by the employees shall be by teams consisting of an equal number of members of each political party. Thirty days before an election the county clerk or board of election commissioners shall submit to the chair of each political party, for his or her approval or disapproval, a list of persons of his or her party proposed to be employed. If a chair fails to notify the election authority of his or her disapproval of any proposed employee within a period of 10 days thereafter the list shall be deemed approved.

10 ILCS 5/24C-14

    (10 ILCS 5/24C-14)
    Sec. 24C-14. Tabulating Votes; Direction; Presence of Public; Computer Operator's Log and Canvass. The procedure for tabulating the votes by the Direct Recording Electronic Voting System shall be under the direction of the election authority and shall conform to the requirements of the Direct Recording Electronic Voting System. During any election-related activity using the automatic Direct Recording Electronic Voting System equipment, the election authority shall make a reasonable effort to dedicate the equipment to vote processing to ensure the security and integrity of the system.
    A reasonable number of pollwatchers shall be admitted to the counting location. Such persons may observe the tabulating process at the discretion of the election authority; however, at least one representative of each established political party and authorized agents of the State Board of Elections shall be permitted to observe this process at all times. No persons except those employed and authorized for the purpose shall touch any ballot, ballot box, return, or equipment.
    The computer operator shall be designated by the election authority and shall be sworn as a deputy of the election authority. In conducting the vote tabulation and canvass, the computer operator must maintain a log which shall include the following information:
        (a) alterations made to programs associated with the
    
vote counting process;
        (b) if applicable, console messages relating to the
    
program and the respective responses made by the operator;
        (c) the starting time for each precinct counted, the
    
number of ballots counted for each precinct, any equipment problems and, insofar as practicable, the number of invalid security designations encountered during that count; and
        (d) changes and repairs made to the equipment during
    
the vote tabulation and canvass.
    The computer operator's log and canvass shall be available for public inspection in the office of the election authority for a period of 60 days following the proclamation of election results. A copy of the computer operator's log and the canvass shall be transmitted to the State Board of Elections upon its request and at its expense.

10 ILCS 5/24C-15

    (10 ILCS 5/24C-15)
    Sec. 24C-15. Official return of precinct; check of totals; audit. The precinct return printed by the Direct Recording Electronic Voting System tabulating equipment shall include the number of ballots cast and votes cast for each candidate and public question and shall constitute the official return of each precinct. In addition to the precinct return, the election authority shall provide the number of applications for ballots in each precinct, the total number of ballots and vote by mail ballots counted in each precinct for each political subdivision and district and the number of registered voters in each precinct. However, the election authority shall check the totals shown by the precinct return and, if there is an obvious discrepancy regarding the total number of votes cast in any precinct, shall have the ballots for that precinct audited to correct the return. The procedures for this audit shall apply prior to and after the proclamation is completed; however, after the proclamation of results, the election authority must obtain a court order to unseal voted ballots or voting devices except for election contests and discovery recounts. The certificate of results, which has been prepared and signed by the judges of election after the ballots have been tabulated, shall be the document used for the canvass of votes for such precinct. Whenever a discrepancy exists during the canvass of votes between the unofficial results and the certificate of results, or whenever a discrepancy exists during the canvass of votes between the certificate of results and the set of totals reflected on the certificate of results, the ballots for that precinct shall be audited to correct the return.
    Prior to the proclamation, the election authority shall test the voting devices and equipment in 5% of the precincts within the election jurisdiction, as well as 5% of the voting devices used in early voting. The precincts and the voting devices to be tested shall be selected after election day on a random basis by the State Board of Elections, so that every precinct and every device used in early voting in the election jurisdiction has an equal mathematical chance of being selected. The State Board of Elections shall design a standard and scientific random method of selecting the precincts and voting devices that are to be tested. The State central committee chair of each established political party shall be given prior written notice of the time and place of the random selection procedure and may be represented at the procedure.
    The test shall be conducted by counting the votes marked on the permanent paper record of each ballot cast in the tested precinct printed by the voting system at the time that each ballot was cast and comparing the results of this count with the results shown by the certificate of results prepared by the Direct Recording Electronic Voting System in the test precinct. The election authority shall test count these votes either by hand or by using an automatic tabulating device other than a Direct Recording Electronic voting device that has been approved by the State Board of Elections for that purpose and tested before use to ensure accuracy. The election authority shall print the results of each test count. If any error is detected, the cause shall be determined and corrected, and an errorless count shall be made prior to the official canvass and proclamation of election results. If an errorless count cannot be conducted and there continues to be difference in vote results between the certificate of results produced by the Direct Recording Electronic Voting System and the count of the permanent paper records or if an error was detected and corrected, the election authority shall immediately prepare and forward to the appropriate canvassing board a written report explaining the results of the test and any errors encountered and the report shall be made available for public inspection.
    The State Board of Elections, the State's Attorney and other appropriate law enforcement agencies, the county chair of each established political party and qualified civic organizations shall be given prior written notice of the time and place of the test and may be represented at the test.
    The results of this post-election test shall be treated in the same manner and have the same effect as the results of the discovery procedures set forth in Section 22-9.1 of this Code.

    Any voting system vendor, person, or other private entity seeking the State Board of Elections' approval of a voting system shall, as part of the approval application, submit to the State Board a non-refundable fee. The State Board of Elections by rule shall establish an appropriate fee structure, taking into account the type of voting system approval that is requested (such as approval of a new system, a modification of an existing system, the size of the modification, etc.). No voting system or modification of a voting system shall be approved unless the fee is paid.
    No vendor, person, or other entity may sell, lease, or loan, or have a written contract, including a contract contingent upon State Board approval of the voting system or voting system component, to sell, lease, or loan, a Direct Recording Electronic Voting System or system component to any election jurisdiction unless the system or system component is first approved by the State Board of Elections pursuant to this Section.

    (a) When a vacancy occurs in the office of State Senator or Representative in the General Assembly, the vacancy shall be filled within 30 days by appointment of the legislative or representative committee of that legislative or representative district of the political party of which the incumbent was a candidate at the time of his election. Prior to holding a meeting to fill the vacancy, the committee shall make public (i) the names of the committeeperson on the appropriate legislative or representative committee, (ii) the date, time, and location of the meeting to fill the vacancy, and (iii) any information on how to apply or submit a name for consideration as the appointee. A meeting to fill a vacancy in office shall be held in the district or virtually, and any meeting shall be accessible to the public. The appointee shall be a member of the same political party as the person he succeeds was at the time of his election, and shall be otherwise eligible to serve as a member of the General Assembly.
    (b) When a vacancy occurs in the office of a legislator elected other than as a candidate of a political party, the vacancy shall be filled within 30 days of such occurrence by appointment of the Governor. The appointee shall not be a member of a political party, and shall be otherwise eligible to serve as a member of the General Assembly. Provided, however, the appropriate body of the General Assembly may, by resolution, allow a legislator elected other than as a candidate of a political party to affiliate with a political party for his term of office in the General Assembly. A vacancy occurring in the office of any such legislator who affiliates with a political party pursuant to resolution shall be filled within 30 days of such occurrence by appointment of the appropriate legislative or representative committee of that legislative or representative district of the political party with which the legislator so affiliates. The appointee shall be a member of the political party with which the incumbent affiliated.
    (c) For purposes of this Section, a person is a member of a political party for 23 months after (i) signing a candidate petition, as to the political party whose nomination is sought; (ii) signing a statement of candidacy, as to the political party where nomination or election is sought; (iii) signing a Petition of Political Party Formation, as to the proposed political party; (iv) applying for and receiving a primary ballot, as to the political party whose ballot is received; or (v) becoming a candidate for election to or accepting appointment to the office of ward, township, precinct or state central committeeperson.
    (d) In making appointments under this Section, each committeeperson of the appropriate legislative or representative committee shall be entitled to one vote for each vote that was received, in that portion of the legislative or representative district which he represents on the committee, by the Senator or Representative whose seat is vacant at the general election at which that legislator was elected to the seat which has been vacated and a majority of the total number of votes received in such election by the Senator or Representative whose seat is vacant is required for the appointment of his successor; provided, however, that in making appointments in legislative or representative districts comprising only one county or part of a county other than a county containing 2,000,000 or more inhabitants, each committeeperson shall be entitled to cast only one vote.
    (e) Appointments made under this Section shall be in writing and shall be signed by members of the legislative or representative committee whose total votes are sufficient to make the appointments or by the Governor, as the case may be. Such appointments shall be filed with the Secretary of State and with the Clerk of the House of Representatives or the Secretary of the Senate, whichever is appropriate.
    (f) An appointment made under this Section shall be for the remainder of the term, except that, if the appointment is to fill a vacancy in the office of State Senator and the vacancy occurs with more than 28 months remaining in the term, the term of the appointment shall expire at the time of the next general election at which time a Senator shall be elected for a new term commencing on the determination of the results of the election and ending on the second Wednesday of January in the second odd-numbered year next occurring. Whenever a Senator has been appointed to fill a vacancy and was thereafter elected to that office, the term of service under the authority of the election shall be considered a new term of service, separate from the term of service rendered under the authority of the appointment.
