Betz v. Pneumo Abex LLC
44 A.3d 27
| Pa. | 2012Background
- Betz sues as executrix for mesothelioma arising from exposure to asbestos in friction products during decades of automotive work.
- Case was selected as a test for admissibility of any-exposure causation theory under Frye general-acceptance standard.
- Dr. Maddox opined that every inhaled asbestos fiber contributes to disease; defendants argued theory is novel and unreliable.
- Judge Colville conducted a Frye hearing, ruled the any-exposure theory was not generally accepted, and precluded it.
- Superior Court en banc reversed, prompting Pennsylvania Supreme Court review of Frye standard and methodology.
- Court addresses whether the Frye challenge was appropriate and how to evaluate extrapolation versus accepted methods.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Was a Frye hearing appropriate? | Betz argues theory is mainstream and not novel. | Colville erred by treating theory as novel requiring Frye. | Yes; Frye hearing appropriate to assess methodology. |
| Is the any-exposure opinion generally accepted in the relevant scientific community? | Maddox's approach is mainstream and supported by Helsinki criteria. | Methodology is not generally accepted; relies on selective literature. | Court found lack of general acceptance; affirmed Frye ruling against admissibility. |
| Is extrapolation/downward extrapolation (downstream from high-dose to low-dose) a valid component of the methodology? | Extrapolation/downward extrapolation is a valid, generally accepted scientific practice. | Downward extrapolation is scientifically problematic and not generally accepted. | Court deemed extrapolationing as lacking adequate support; rejected for this theory. |
| Did the trial court abuse its discretion reviewing the Frye evidence? | Superior Court relied on record; Colville's findings were reasonable. | Superior Court abused discretion by discounting record support for general acceptance. | Yes; the Supreme Court reversed, remanding for other preserved issues. |
| Should the case be governed by the frequency-regularity-proximity standard (Gregg) or by any-exposure causation? | Any-exposure theory is valid for substantial-factor causation and fits burden shift. | Any-exposure conflicts with substantial-factor causation and dose-response. | Court rejects any-exposure as sole basis for substantial-factor causation; remands. |
