2021 Illinois Compiled Statutes|Chapter 10 - ELECTIONS|10 ILCS 5/ - Election Code.|Article 24C - Direct Recording Electronic Voting Systems

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.
