Illinois § 115-20

§ 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.
