Richardson v. Union Pacific Railroad
386 S.W.3d 77
Ark. Ct. App.2011Background
- Richardson sued Union Pacific under FELA alleging cancer from diesel exhaust, creosote, herbicides, and pesticides exposure during 1971–2006 employment.
- Pulaski County Circuit Court granted in limine exclusion of Richardson’s expert testimony, then summary judgment for UP since causation proof was lacking.
- Arkansas law uses an abuse-of-discretion standard to review trial court gatekeeping of Daubert/Foote admissibility decisions.
- FELA allows broader causation considerations than state tort law; general and specific causation must be proven, with general causation evaluated before specific.
- Richardson presented Wabeke (industrial hygienist/toxicologist) and Brautbar (MD) as experts; UP challenged their reliability under Rule 702 and Daubert/Foote.
- The trial court excluded both experts as unreliable or unhelpful; the appellate court affirmed, holding no admissible causation evidence remained.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Standard of review for Daubert/Foote rulings | Abuse-of-discretion misapplied; should be de novo review. | Abuse-of-discretion governs gatekeeping and reliability determinations. | Abuse-of-discretion applies; review limits on reliability assessment and admissibility. |
| Necessity of precise exposure data for causation | Qualified experts need not provide exact ppm; substantial exposure suffices. | Precise exposure data or robust methodology is required to support causation. | Courts require general and specific causation methods; lacking reliable exposure data, admissibility upheld. |
| Applicability of Daubert/Foote framework to toxic-tort evidence | Nebraska/Kimberly approaches should guide admissibility in toxic torts. | Daubert/Foote framework governs admissibility; gatekeeping is flexible per case. | Daubert/Foote framework applies; Kumho allows flexible, case-specific reliability analysis. |
| Admissibility of expert opinions on general/specific causation | Evidence supports general/specific causation via literature and differential etiology. | Study flaws, selective citations, and lack of exposure data render opinions unreliable. | Trial court did not abuse discretion in excluding opinions; insufficient reliable causation evidence. |
