9    Sec. 8-2901. Opinion testimony by lay witnesses. If the
10witness is not testifying as an expert, the witness' testimony
11in the form of opinions or inferences is limited to those
12opinions or inferences which are (a) rationally based on the
13perception of the witness, (b) helpful to a clear understanding
14of the witness' testimony or the determination of a fact in
15issue, and (c) not based on scientific, technical, or other
16specialized knowledge within the scope of Section 8-2903.
17    (735 ILCS 5/8-2902 new)
18    Sec. 8-2902. Testimony by experts. If scientific,
19technical, or other specialized knowledge will assist the trier

HB5807- 2 -LRB097 18194 AJO 63418 b

1experience, training, or education may testify thereto in the
2form of an opinion or otherwise, if (a) the testimony is based
3upon sufficient facts or data, (b) the testimony is the product

9or data in the particular case upon which an expert bases an
10opinion or inference may be those perceived by or made known to

13opinions or inferences upon the subject, the facts or data need
14not be admissible in evidence in order for the opinion or
15inference to be admitted. Facts or data that are otherwise
16inadmissible shall not be disclosed to the jury by the
17proponent of the opinion or inference unless the court
18determines that their probative value in assisting the jury to

20prejudicial effect.
21    (735 ILCS 5/8-2904 new)
22    Sec. 8-2904. Bars to expert testimony.
23    (a) A witness qualified as an expert by knowledge, skill,

2expert is qualified.
3    (b) An expert witness may receive a reasonable and
4customary fee for the rendering of professional services,
5provided that the testimony of an expert witness shall not be
6admitted if any such compensation is contingent on the outcome

8being offered.
9    (735 ILCS 5/8-2905 new)
10    Sec. 8-2905. Mandatory pre-trial hearing. If the witness is
11testifying as an expert, then upon motion of a party, the court

14satisfies the requirements of Sections 8-2902, 8-2903, and
158-2904. The court shall allow sufficient time for a hearing and
16shall rule on the qualifications of the witness to testify as
17an expert and whether or not the testimony satisfies the
18requirements of Sections 8-2902, 8-2903, and 8-2904. Such
19hearing and ruling shall be completed no later than the final
20pre-trial hearing. The trial court's ruling shall set forth the
21findings of fact and conclusions of law upon which the order to
22admit or exclude expert evidence is based.

4disclose to other parties the identity of any person who may be
5used at trial to present expert evidence.
6    (b) Except as otherwise stipulated or directed by the
7court, this disclosure shall, with respect to a witness who is
8retained or specially employed to provide expert testimony in
9the case or whose duties as an employee of the party regularly
10involve giving expert testimony, be accompanied by a written
11report prepared and signed by the witness. The report shall
12contain a complete statement of all opinions to be expressed
13and the basis and reasons therefor; the data or other
14information considered by the witness in forming the opinions;
15any exhibits to be used as a summary of or support for the
16opinions; the qualifications of the witness, including a list
17of all publications authored by the witness within the
18preceding 10 years; the compensation to be paid for the study

23sequence directed by the court. In the absence of other
24directions from the court or stipulation by the parties, the
25disclosures shall be made at least 90 days before the trial
26date or the date the case is to be ready for trial or, if the



HB5807- 5 -LRB097 18194 AJO 63418 b

1evidence is intended solely to contradict or rebut evidence on
2the same subject matter identified by another party under
3paragraph (b), within 30 days after the disclosure made by the
4other party.
5    (d) A party may depose any person who has been identified
6as an expert whose opinions may be presented at trial. If a
7report from the expert is required under paragraph (b), the
8deposition shall not be conducted until after the report is
10    (735 ILCS 5/8-2907 new)
11    Sec. 8-2907. Interpretation. In interpreting and applying
12this Act, the courts of this State shall follow the opinions of
13the Supreme Court of the United States in Daubert v. Merrell
14Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), General
15Electric Co. v. Joiner, 522 U.S. 136 (1997), Kumho Tire Co.
16Ltd. v. Carmichael, 526 U.S. 137 (1999), Weisgram v. Marley,
17528 U.S. 440 (2000), and their progeny; moreover, the courts of
18this State may draw from other precedents binding in the
19federal courts of this State applying the standards announced
20by the Supreme Court of the United States in the foregoing
22    (735 ILCS 5/8-2908 new)
23    Sec. 8-2908. Interlocutory appeal. Interlocutory appeal of
24a ruling on the admissibility of expert evidence shall be



HB5807- 6 -LRB097 18194 AJO 63418 b

1available at the discretion of the appellate court. In deciding
2whether to grant the interlocutory appeal, the court shall
3consider whether: (i) the ruling involved any challenge to the
4constitutionality of this Act; (ii) the ruling will help prove
5or disprove criminal liability; or (iii) the ruling will help
6establish civil liability at or above $75,000, where the
7testimony could be outcome-determinative for establishing
8liability or determining damages. Neither a party's failure to
9seek interlocutory appeal nor an appellate court's decision to
10deny a motion for interlocutory appeal shall waive a party's
11right to appeal a ruling on the admissibility of expert
12evidence after an entry of judgment in the case.
13    (735 ILCS 5/8-2909 new)
14    Sec. 8-2909. Standard of review.
15    (a) As the proper construction of the expert evidence
16admissibility framework prescribed by this Act is a question of
17law, the reviewing court shall apply a de novo standard of
18review in determining whether the trial court fully applied the
19proper legal standard in considering the admissibility of
20expert evidence.
21    (b) As the application of this Act to determine the
22admissibility of expert testimony is a question of fact, the
23reviewing court shall apply an abuse of discretion standard in
24determining whether the trial court properly admitted or
25excluded particular expert evidence.



HB5807- 7 -LRB097 18194 AJO 63418 b

7amendatory Act of the 97th General Assembly.
