Illinois Compiled Statutes
Information maintained by the Legislative
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
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the
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.

(10 ILCS 5/24C-11)
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
(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
(m) All system voting devices shall incorporate at least 3
memories in the machine itself and in its programmable memory
(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
(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.
