613 F. App'x 340
5th Cir.2015Background
- Plaintiffs Macy and Santos sued Whirlpool after alleged carbon monoxide (CO) exposure from a KitchenAid gas range in their Texas home; Center Point Energy technician "red-tagged" the range after recording 2,000 ppm in the oven probe.
- Plaintiffs claimed low-level, chronic CO exposure caused neurological injuries; they relied on experts Dr. David Penney (causation) and Paul Carper (design/standards compliance and field testing).
- Whirlpool moved to exclude both experts under Fed. R. Evid. 702 and for summary judgment arguing the range met applicable standards and Plaintiffs lacked admissible proof of causation or excess CO emissions.
- The district court struck both expert reports and granted Whirlpool summary judgment for lack of admissible evidence on (1) that Plaintiffs’ symptoms were caused by CO poisoning and (2) that the range produced CO above industry standards.
- The Fifth Circuit affirmed, holding the district court did not abuse its gatekeeping discretion in excluding the experts and that summary judgment was proper given the exclusions.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of general-causation expert (Dr. Penney) | Penney: literature (including WHO piece and case series) supports that low-level chronic CO can cause Plaintiffs’ injuries | Whirlpool: cited literature is insufficient, inapposite, and relies on non-endorsed WHO guideline | Excluded — court found studies relied on were not sufficiently reliable or directly applicable under Rule 702/Daubert |
| Admissibility of design/standards expert (Carper) | Carper: field testing showed the range produced unsafe CO and failed ANSI Z21.1 | Whirlpool: Carper lacks relevant qualifications on CO/appliance standards; his testing also did not follow ANSI protocol | Excluded — Carper not shown qualified for gas appliance/CO opinions; methodology unreliable |
| Sufficiency of evidence for causation | Macy/Santos: expert testimony would show general and specific causation from the range | Whirlpool: without admissible experts, Plaintiffs have no reliable proof of causation | Summary judgment for Whirlpool — Plaintiffs lacked admissible evidence to show causation |
| Sufficiency of evidence that range exceeded industry standards | Plaintiffs: Carper’s testing and opinions show noncompliance with ANSI standard | Whirlpool: testing/opinions inadmissible and, per record, range met standards when properly tested | Summary judgment for Whirlpool — no admissible evidence of standards violation |
