Yates v. Ford Motor Co.
113 F. Supp. 3d 841
E.D.N.C.2015Background
- Plaintiff Graham Yates alleges pleural mesothelioma caused by exposure to asbestos in defendants’ brake products (Ford and Honeywell/Bendix). Remaining claims: negligence and failure to warn.
- Defendants moved under Daubert to exclude experts Eugene Mark, M.D.; Arnold Brody, Ph.D.; and portions of industrial hygienist Steve Hays’s opinions, arguing unreliable methodology and reliance on an “each/any exposure” theory.
- The court held a multi-day Daubert hearing and received expert depositions and reports. Key contested points: (1) acceptance or rejection of the “each and every exposure” (single-fiber/any-exposure) theory; (2) whether experts established hazardous exposure levels for chrysotile brake asbestos and compared them reliably to Yates’s actual exposures; (3) whether Mark’s methods (including reliance on visible-dust metrics, epidemiology, and Helsinki Criteria) satisfy Rule 702.
- The court excluded any testimony adopting the “each and every exposure” theory and excluded opinions asserting that brake dust (or chrysotile from brakes) causes mesothelioma when unsupported.
- The court excluded Dr. Mark entirely for failing to (a) define reliable hazardous exposure levels for chrysotile, (b) apply a reliable method to compare Yates’s exposures to hazardous levels, and (c) support his visible-dust calculations and study selection process.
- The court limited Brody by excluding his “above-background / each and every exposure” opinion but allowed the remainder of his cellular-level testimony; it allowed Hays to testify on risk statements (not causation via any-exposure theory) but barred any unsupported opinion that brake dust causes mesothelioma.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of “each/any exposure” theory | Experts may attribute mesothelioma to any exposure above background; regulatory statements support no safe threshold | Theory is untestable, lacks peer-review, error rates, and sufficient facts/data; courts exclude it | Excluded: court barred testimony adopting “each and every exposure” theory (Brody’s portion excluded) |
| Whether experts can opine brake dust/chrysotile from brakes causes mesothelioma | Experts claim visible brake dust and cited literature support causation | Defendants: opinion lacks fiber-type-specific hazard levels, flawed conversions, and unreliable extrapolations | Excluded: testimony that brake dust causes mesothelioma is barred absent proper foundation (Mark excluded on this ground; Brody/Hays cannot offer unsupported causation opinion) |
| Reliability of Mark’s methodology to establish hazardous levels and compare to plaintiff exposure | Mark relied on visible-dust metrics, selected epidemiological studies, and Helsinki Criteria to attribute causation | Defendants: Mark’s visible-dust conversions are inconsistent/unsupported; study selection was selective; Helsinki Criteria does not allocate causation among multiple exposures | Excluded: Mark’s causation opinion excluded for failing to establish hazardous chrysotile levels, unreliable calculations, selective literature use, and no reliable exposure comparison |
| Scope of Brody and Hays testimony post-Daubert | Plaintiffs contend Brody/Hays provide cellular, mechanistic, and risk evidence relevant to causation | Defendants seek broad exclusion based on any-exposure reliance and lack of fit to the facts | Partially granted: Brody’s “each and every exposure/above-background” opinion excluded but his cellular-level testimony retained; Hays may testify about risk and exposure increases but not assert that every exposure is a legal cause or that brake dust per se causes mesothelioma without foundation |
