Jamie Wilden v. Laury Transp.
901 F.3d 644
6th Cir.2018Background
- In 2013 Janice Wilden and her infant son were in a side-underride crash with an 18‑wheel trailer manufactured by Great Dane; Janice suffered severe brain injuries. The trailer (manufactured 1998) lacked side-underride protection.
- Wilden sued Great Dane in a Kentucky products‑liability (crashworthiness) action alleging an alternative, safer design existed: a horizontally telescoping side guard that would extend when the trailer’s rear axle was slid rearward.
- Plaintiffs proffered two experts (Ponder and Enz) who offered computer modeling and design drawings of a telescoping side guard; no horizontally telescoping side guard has ever been built or crash‑tested in the real world.
- The district court excluded the experts’ testimony under Federal Rule of Evidence 702/Daubert primarily because (1) the telescoping design had not been physically prototyped or crash‑tested, (2) it lacked industry general acceptance, and (3) the proposed design was developed for this litigation.
- The district court granted summary judgment for Great Dane on the ground that plaintiffs’ crashworthiness claim depended on the excluded expert testimony; the Sixth Circuit affirmed, finding no abuse of discretion in the Daubert rulings and that summary judgment was therefore proper.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility under Rule 702 (testing) | Ponder/Enz’s computer modeling and prior related work suffice; physical prototype not required. | No one has built/tested a horizontal telescoping side guard; physical prototype testing is necessary to validate a novel safety device. | Court upheld exclusion: district court permissibly required physical‑prototype/testing given novelty and complexity. |
| General acceptance (Daubert factor) | Telescoping side guard concepts appear in patents and literature; feasibility is recognized. | Design has never been built or adopted by industry; thus not generally accepted. | Court held lack of real‑world use/support meant general‑acceptance factor weighed against admissibility. |
| Prepared‑for‑litigation (bias/reliability) | Experts have experience in underride protection generally; their work is reliable. | The specific telescoping design was developed after litigation began, not from independent research. | Court treated this factor as neutral-to-weighing-against admission because the particular design was litigation‑driven. |
| Disposition (summary judgment) | Expert proof was available and admissible to prove alternative design and enhanced injury. | Without admissible expert proof, crashworthiness claim cannot be sustained. | Court affirmed summary judgment for Great Dane because plaintiffs’ claim depended on excluded expert testimony. |
