11    (735 ILCS 5/8-3007 new)
12    Sec. 8-3007. Interpretation. In interpreting and applying
13this Part, the courts of this State shall follow the opinions
14of the United States Supreme Court in Daubert v. Merrell Dow
15Pharmaceuticals, Inc., 509 U.S. 579 (1993), General Electric
16Co. v. Joiner, 522 U.S. 136 (1997), Kumho Tire Co. Ltd. v.
17Carmichael, 526 U.S. 137 (1999), Weisgram v. Marley, 528 U.S.
18440 (2000), and their progeny; moreover, the courts of this
19State may draw from other precedents applying the standards
20announced by the United States Supreme Court in the foregoing
21cases and binding in the federal courts of this State.
22    (735 ILCS 5/8-3008 new)
23    Sec. 8-3008. Interlocutory appeal. Interlocutory appeal of

2deciding whether to grant the interlocutory appeal, the court
3shall consider whether: (i) the ruling involved any challenge
4to the constitutionality of this Part; (ii) the ruling will
5help prove or disprove criminal liability; or (iii) the ruling
6will help establish civil liability at or above $75,000, where
7the testimony 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 5/8-3009 new)
14    Sec. 8-3009. Standard of review.
15    (a) The proper construction of the expert evidence
16admissibility framework under this Part is a question of law;
17therefore, the reviewing court shall apply a de novo standard
18of review in determining whether the trial court fully applied
19the proper legal standard in considering the admissibility of
20expert evidence.
21    (b) The application of this Part to determine the
22admissibility of expert testimony is a question of fact;
23therefore, the reviewing court shall apply an abuse of
24discretion standard in determining whether the trial court
25properly admitted or excluded particular expert evidence.
