Babczak v. Abbvie Corporation

Court IL Appellate, 3rd District
Filed Monday, May 18, 2026
Citation 2026 IL App (3d) 250414

Key Takeaways

  • 1 Without a qualifying expert, a strict product liability plaintiff cannot survive summary judgment on causation.
  • 2 A product recall and post-surgery injuries alone are legally insufficient to establish causation in a product liability claim.
  • 3 Relevant for plaintiffs' and defense counsel in product liability cases involving complex medical causation and expert disclosure requirements.

Summary

Robert Babczak filed a strict product liability claim against AbbVie Corporation alleging that its XEN gel stent — an intraocular device used to treat glaucoma — caused him excessive tearing, irritation, and a blind spot due to chemical residue (a polishing compound) left on the device. After repeated failures to properly disclose expert witnesses under Illinois Supreme Court Rules 213(f)(2) and (f)(3), AbbVie moved for summary judgment arguing Babczak could not establish causation without expert testimony. The trial court granted AbbVie's motion and denied Babczak's cross-motion for partial summary judgment on liability. Babczak appealed both rulings, along with challenges to a protective order, interrogatory limits, and the striking of his expert disclosure.

The Illinois Appellate Court, Third District, affirmed on all issues. AbbVie met its initial summary judgment burden by presenting deposition testimony from Babczak's own treating physicians establishing that his injuries were caused by underlying glaucoma and surgical side effects — not chemical residue. The burden then shifted to Babczak, who failed to produce admissible evidence beyond speculation. The court held that expert testimony was necessary because whether a polishing agent or glutaraldehyde could cause prolonged eye irritation is beyond common knowledge. Babczak's final expert, Dr. Chaku, expressly declined to opine on causation, rendering her disclosure non-compliant with Rule 213(f)(3).

For practicing attorneys, this case underscores that in complex medical product liability cases, a plaintiff must secure a properly disclosed, causation-opining expert or face summary judgment. Courts will not infer defect or causation from a product recall or the mere occurrence of post-surgical injuries. Additionally, the decision illustrates that repeated failures to comply with expert disclosure rules — even after multiple court-granted extensions — will not be excused.

Key Holdings

1. In a strict product liability case involving complex medical causation, expert testimony is required to establish that a product defect caused the plaintiff's injuries; without a properly disclosed expert, summary judgment for the defendant is proper.

2. A product recall and the occurrence of post-surgery injuries are legally insufficient, standing alone, to establish causation as a matter of law in a strict product liability claim.

3. An expert disclosure under Rule 213(f)(3) is non-compliant — and subject to being stricken — where the expert expressly declines to opine on causation, defect, or the presence of the alleged harmful substance.

4. A trial court does not abuse its discretion in denying further leave to disclose experts where the plaintiff has already received multiple extensions and warnings and continues to submit non-compliant disclosures.
