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.

CRIMINAL PROCEDURE
(725 ILCS 5/) Code of Criminal Procedure of 1963.

725 ILCS 5/115-18

    (725 ILCS 5/115-18)
    Sec. 115-18. Employee protected. No employer shall discharge or terminate, or threaten to discharge or terminate, from his or her employment, or otherwise punish or penalize his or her employee who is a witness to a crime, because of time lost from regular employment resulting from his or her attendance at a proceeding under subpoena issued in any criminal proceeding relative to the crime. An employer who knowingly or intentionally violates this Section shall be proceeded against and punished for contempt of court. This Section shall not be construed as requiring an employer to pay an employee for time lost resulting from attendance at any proceeding.

725 ILCS 5/115-19

    (725 ILCS 5/115-19)
    Sec. 115-19. Polygraph. In the course of a criminal trial the court shall not require, request, or suggest that the defendant submit to a polygraphic detection deception test, commonly known as a lie detector test, to questioning under the effect of thiopental sodium, or to any other test or questioning by means of a mechanical device or chemical substance.

725 ILCS 5/115-20

    (725 ILCS 5/115-20)
    Sec. 115-20. Evidence of prior conviction.
    (a) Evidence of a prior conviction of a defendant for domestic battery, aggravated battery committed against a family or household member as defined in Section 112A-3, stalking, aggravated stalking, or violation of an order of protection is admissible in a later criminal prosecution for any of these types of offenses when the victim is the same person who was the victim of the previous offense that resulted in conviction of the defendant.
    (b) If the defendant is accused of an offense set forth in subsection (a) or the defendant is tried or retried for any of the offenses set forth in subsection (a), evidence of the defendant's conviction for another offense or offenses set forth in subsection (a) may be admissible (if that evidence is otherwise admissible under the rules of evidence) and may be considered for its bearing on any matter to which it is relevant if the victim is the same person who was the victim of the previous offense that resulted in conviction of the defendant.
    (c) In weighing the probative value of the evidence against undue prejudice to the defendant, the court may consider:
        (1) the proximity in time to the charged or predicate
    
offense;
        (2) the degree of factual similarity to the charged
    
or predicate offense; or
        (3) other relevant facts and circumstances.
    (d) In a criminal case in which the prosecution intends to offer evidence under this Section, it must disclose the evidence, including statements of witnesses or a summary of the substance of any testimony, at a reasonable time in advance of trial, or during trial if the court excuses pretrial notice on good cause shown.
    (e) In a criminal case in which evidence is offered under this Section, proof may be made by specific instances of conduct as evidenced by proof of conviction, testimony as to reputation, or testimony in the form of an expert opinion, except that the prosecution may offer reputation testimony only after the opposing party has offered that testimony.
(Source: P.A. 90-387, eff. 1-1-98.)

725 ILCS 5/115-21

    (725 ILCS 5/115-21)
    Sec. 115-21. Informant testimony.
    (a) For the purposes of this Section, "informant" means someone who is purporting to testify about admissions made to him or her by the accused while detained or incarcerated in a penal institution contemporaneously.
    (b) This Section applies to any criminal proceeding brought under Sections 9-1, 9-1.2, 9-2, 9-2.1, 9-3, 9-3.2, 9-3.3, 11-1.30, 11-1.40, or 20-1.1 of the Criminal Code of 1961 or the Criminal Code of 2012, in which the prosecution attempts to introduce evidence of incriminating statements made by the accused to or overheard by an informant.
    (c) Except as provided in subsection (d-5), in any case under this Section, the prosecution shall disclose at least 30 days prior to a relevant evidentiary hearing or trial:
        (1) the complete criminal history of the informant;
        (2) any deal, promise, inducement, or benefit that
    
the offering party has made or will make in the future to the informant;
        (3) the statements made by the accused;
        (4) the time and place of the statements, the time
    
and place of their disclosure to law enforcement officials, and the names of all persons who were present when the statements were made;
        (5) whether at any time the informant recanted that
    
testimony or statement and, if so, the time and place of the recantation, the nature of the recantation, and the names of the persons who were present at the recantation;
        (6) other cases in which the informant testified,
    
provided that the existence of such testimony can be ascertained through reasonable inquiry and whether the informant received any promise, inducement, or benefit in exchange for or subsequent to that testimony or statement; and
        (7) any other information relevant to the informant's
    
credibility.
    (d) Except as provided in subsection (d-5), in any case under this Section, the prosecution shall timely disclose at least 30 days prior to any relevant evidentiary hearing or trial its intent to introduce the testimony of an informant. The court shall conduct a hearing to determine whether the testimony of the informant is reliable, unless the defendant waives such a hearing. If the prosecution fails to show by a preponderance of the evidence that the informant's testimony is reliable, the court shall not allow the testimony to be heard at trial. At this hearing, the court shall consider the factors enumerated in subsection (c) as well as any other factors relating to reliability.
    (d-5) The court may permit the prosecution to disclose its intent to introduce the testimony of an informant with less notice than the 30-day notice required under subsections (c) and (d) of this Section if the court finds that the informant was not known prior to the 30-day notice period and could not have been discovered or obtained by the exercise of due diligence by the prosecution prior to the 30-day notice period. Upon good cause shown, the court may set a reasonable notice period under the circumstances or may continue the trial on its own motion to allow for a reasonable notice period, which motion shall toll the speedy trial period under Section 103-5 of this Code for the period of the continuance.
    (e) If a lawful recording of an incriminating statement is made of an accused to an informant or made of a statement of an informant to law enforcement or the prosecution, including any deal, promise, inducement, or other benefit offered to the informant, the accused may request a reliability hearing under subsection (d) of this Section and the prosecution shall be subject to the disclosure requirements of subsection (c) of this Section.
    (f) (Blank).
    (g) This Section applies to all criminal prosecutions under subsection (b) of this Section on or after the effective date of this amendatory Act of the 100th General Assembly.

        (1) whether the witness has received or been promised
    
anything, including pay, immunity from prosecution, leniency in prosecution, or personal advantage, in exchange for testimony;

(Source: P.A. 86-391.)

725 ILCS 5/116-2.1

    (725 ILCS 5/116-2.1)
    Sec. 116-2.1. Motion to vacate prostitution convictions for sex trafficking victims.
    (a) A motion under this Section may be filed at any time following the entry of a verdict or finding of guilty where the conviction was under Section 11-14 (prostitution) or Section 11-14.2 (first offender; felony prostitution) of the Criminal Code of 1961 or the Criminal Code of 2012 or a similar local ordinance and the defendant's participation in the offense was a result of having been a trafficking victim under Section 10-9 (involuntary servitude, involuntary sexual servitude of a minor, or trafficking in persons) of the Criminal Code of 1961 or the Criminal Code of 2012; or a victim of a severe form of trafficking under the federal Trafficking Victims Protection Act (22 U.S.C. Section 7102(13)); provided that:
        (1) a motion under this Section shall state why the
    
facts giving rise to this motion were not presented to the trial court, and shall be made with due diligence, after the defendant has ceased to be a victim of such trafficking or has sought services for victims of such trafficking, subject to reasonable concerns for the safety of the defendant, family members of the defendant, or other victims of such trafficking that may be jeopardized by the bringing of such motion, or for other reasons consistent with the purpose of this Section; and
        (2) reasonable notice of the motion shall be served
    
upon the State.
    (b) The court may grant the motion if, in the discretion of the court, the violation was a result of the defendant having been a victim of human trafficking. Evidence of such may include, but is not limited to:
        (1) certified records of federal or State court
    
proceedings which demonstrate that the defendant was a victim of a trafficker charged with a trafficking offense under Section 10-9 of the Criminal Code of 1961 or the Criminal Code of 2012, or under 22 U.S.C. Chapter 78;
        (2) certified records of "approval notices" or "law
    
enforcement certifications" generated from federal immigration proceedings available to such victims; or
        (3) a sworn statement from a trained professional
    
staff of a victim services organization, an attorney, a member of the clergy, or a medical or other professional from whom the defendant has sought assistance in addressing the trauma associated with being trafficked.
    Alternatively, the court may consider such other evidence as it deems of sufficient credibility and probative value in determining whether the defendant is a trafficking victim or victim of a severe form of trafficking.
    (c) If the court grants a motion under this Section, it must vacate the conviction and may take such additional action as is appropriate in the circumstances.

725 ILCS 5/116-3

    (725 ILCS 5/116-3)
    Sec. 116-3. Motion for fingerprint, Integrated Ballistic Identification System, or forensic testing not available at trial or guilty plea regarding actual innocence.
    (a) A defendant may make a motion before the trial court that entered the judgment of conviction in his or her case for the performance of fingerprint, Integrated Ballistic Identification System, or forensic DNA testing, including comparison analysis of genetic marker groupings of the evidence collected by criminal justice agencies pursuant to the alleged offense, to those of the defendant, to those of other forensic evidence, and to those maintained under subsection (f) of Section 5-4-3 of the Unified Code of Corrections, on evidence that was secured in relation to the trial or guilty plea which resulted in his or her conviction, and:
        (1) was not subject to the testing which is now
    
requested at the time of trial; or
        (2) although previously subjected to testing, can be
    
subjected to additional testing utilizing a method that was not scientifically available at the time of trial that provides a reasonable likelihood of more probative results.
    Reasonable notice of the motion shall be served upon the State.
    (b) The defendant must present a prima facie case that:
        (1) identity was the issue in the trial or guilty
    
plea which resulted in his or her conviction; and
        (2) the evidence to be tested has been subject to a
    
chain of custody sufficient to establish that it has not been substituted, tampered with, replaced, or altered in any material aspect.
    (c) The trial court shall allow the testing under reasonable conditions designed to protect the State's interests in the integrity of the evidence and the testing process upon a determination that:
        (1) the result of the testing has the scientific
    
potential to produce new, noncumulative evidence (i) materially relevant to the defendant's assertion of actual innocence when the defendant's conviction was the result of a trial, even though the results may not completely exonerate the defendant, or (ii) that would raise a reasonable probability that the defendant would have been acquitted if the results of the evidence to be tested had been available prior to the defendant's guilty plea and the petitioner had proceeded to trial instead of pleading guilty, even though the results may not completely exonerate the defendant; and
        (2) the testing requested employs a scientific method
    
generally accepted within the relevant scientific community.
    (d) If evidence previously tested pursuant to this Section reveals an unknown fingerprint from the crime scene that does not match the defendant or the victim, the order of the Court shall direct the prosecuting authority to request the Illinois State Police Bureau of Forensic Science to submit the unknown fingerprint evidence into the FBI's Integrated Automated Fingerprint Identification System (AIFIS) for identification.
    (e) In the court's order to allow testing, the court shall order the investigating authority to prepare an inventory of the evidence related to the case and issue a copy of the inventory to the prosecution, the petitioner, and the court.
    (f) When a motion is filed to vacate based on favorable post-conviction testing results, the State may, upon request, reactivate victim services for the victim of the crime during the pendency of the proceedings, and, as determined by the court after consultation with the victim or victim advocate, or both, following final adjudication of the case.

725 ILCS 5/116-4

    (725 ILCS 5/116-4)
    Sec. 116-4. Preservation of evidence for forensic testing.
    (a) Before or after the trial in a prosecution for a violation of Section 11-1.20, 11-1.30, 11-1.40, 11-1.50, 11-1.60, 12-13, 12-14, 12-14.1, 12-15, or 12-16 of the Criminal Code of 1961 or the Criminal Code of 2012 or in a prosecution for an offense defined in Article 9 of that Code, or in a prosecution for an attempt in violation of Section 8-4 of that Code of any of the above-enumerated offenses, unless otherwise provided herein under subsection (b) or (c), a law enforcement agency or an agent acting on behalf of the law enforcement agency shall preserve, subject to a continuous chain of custody, any physical evidence in their possession or control that is reasonably likely to contain forensic evidence, including, but not limited to, fingerprints or biological material secured in relation to a trial and with sufficient documentation to locate that evidence.
    (b) After a judgment of conviction is entered, the evidence shall either be impounded with the Clerk of the Circuit Court or shall be securely retained by a law enforcement agency. Retention shall be until the completion of the sentence, including the period of mandatory supervised release for the offense, or January 1, 2006, whichever is later, for any conviction for an offense or an attempt of an offense defined in Article 9 of the Criminal Code of 1961 or the Criminal Code of 2012 or in Section 11-1.20, 11-1.30, 11-1.40, 11-1.50, 11-1.60, 12-13, 12-14, 12-14.1, 12-15, or 12-16 of the Criminal Code of 1961 or the Criminal Code of 2012 or for 7 years following any conviction for any other felony for which the defendant's genetic profile may be taken by a law enforcement agency and submitted for comparison in a forensic DNA database for unsolved offenses.
    (c) After a judgment of conviction is entered, the law enforcement agency required to retain evidence described in subsection (a) may petition the court with notice to the defendant or, in cases where the defendant has died, his estate, his attorney of record, or an attorney appointed for that purpose by the court for entry of an order allowing it to dispose of evidence if, after a hearing, the court determines by a preponderance of the evidence that:
        (1) it has no significant value for forensic science
    
analysis and should be returned to its rightful owner, destroyed, used for training purposes, or as otherwise provided by law; or
        (2) it has no significant value for forensic science
    
analysis and is of a size, bulk, or physical character not usually retained by the law enforcement agency and cannot practicably be retained by the law enforcement agency; or
        (3) there no longer exists a reasonable basis to
    
require the preservation of the evidence because of the death of the defendant.
    (d) The court may order the disposition of the evidence if the defendant is allowed the opportunity to take reasonable measures to remove or preserve portions of the evidence in question for future testing.
    (d-5) Any order allowing the disposition of evidence pursuant to subsection (c) or (d) shall be a final and appealable order. No evidence shall be disposed of until 30 days after the order is entered, and if a notice of appeal is filed, no evidence shall be disposed of until the mandate has been received by the circuit court from the appellate court.
    (d-10) All records documenting the possession, control, storage, and destruction of evidence and all police reports, evidence control or inventory records, and other reports cited in this Section, including computer records, must be retained for as long as the evidence exists and may not be disposed of without the approval of the Local Records Commission.
    (e) In this Section, "law enforcement agency" includes any of the following or an agent acting on behalf of any of the following: a municipal police department, county sheriff's office, any prosecuting authority, the Illinois State Police, or any other State, university, county, federal, or municipal police unit or police force.
    "Biological material" includes, but is not limited to, any blood, hair, saliva, or semen from which genetic marker groupings may be obtained.

725 ILCS 5/116-5

    (725 ILCS 5/116-5)
    Sec. 116-5. Motion for DNA database search (genetic marker groupings comparison analysis).
    (a) Upon motion by a defendant charged with any offense where DNA evidence may be material to the defense investigation or relevant at trial, a court may order a DNA database search by the Illinois State Police. Such analysis may include comparing:
        (1) the genetic profile from forensic evidence that
    
was secured in relation to the trial against the genetic profile of the defendant,
        (2) the genetic profile of items of forensic evidence
    
secured in relation to trial to the genetic profile of other forensic evidence secured in relation to trial, or
        (3) the genetic profiles referred to in subdivisions
    
(1) and (2) against:
            (i) genetic profiles of offenders maintained
        
under subsection (f) of Section 5-4-3 of the Unified Code of Corrections, or
            (ii) genetic profiles, including but not limited
        
to, profiles from unsolved crimes maintained in state or local DNA databases by law enforcement agencies.
    (b) If appropriate federal criteria are met, the court may order the Illinois State Police to request the National DNA index system to search its database of genetic profiles.
    (c) If requested by the defense, a defense representative shall be allowed to view any genetic marker grouping analysis conducted by the Illinois State Police. The defense shall be provided with copies of all documentation, correspondence, including digital correspondence, notes, memoranda, and reports generated in relation to the analysis.
    (d) Reasonable notice of the motion shall be served upon the State.
