Pitts v. Genie Indus.
921 N.W.2d 597
Neb.2019Background
- Trevor Pitts, an electrician, was injured when a Genie TZ-34/20 aerial lift tipped over while he was ~30 ft above ground; left-rear outrigger was retracted at the scene.
- Lift had a history of repairs (~30 work orders over 2 years) including issues with auto-leveling and limit switches; a taped-over button was observed on the platform control.
- Genie manufactured >4,600 of this model type, tested functions at manufacture, and was unaware of other similar tip-over incidents; Genie contended post-sale alterations or repairs could explain the malfunction.
- Plaintiffs (Pitts and wife) sued for strict liability (design and manufacturing defects, failure to warn), negligence, and breach of implied warranty.
- Plaintiffs’ sole expert, electrical engineer Dr. John Boye, opined generally that an electrical malfunction caused the tip-over and identified multiple possible causes (some design-related, some post-sale or component failures), but could not identify the specific cause; he also proposed, untested and non-peer-reviewed, an alternative four-position keyed switch.
- The district court excluded Boye’s alternative-design testimony as unreliable, admitted limited design-related opinions, but granted summary judgment for Genie because Boye’s causation opinion was speculative and the malfunction theory was inapplicable where specific design defects were alleged.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Boye's testimony created a factual dispute on causation for design-defect strict liability | Boye tied several possible electrical failures to design shortcomings and argued design defects made the lift unreasonably dangerous | Boye offered only possibilities; no expert tied a specific design defect to the accident | Court: Boye's causation opinions were speculative; insufficient to create genuine issue of material fact; summary judgment affirmed |
| Admissibility of Boye's alternative-design opinion (four-position switch) | Boye proposed a safer alternative that would have isolated outrigger power | Genie: Boye lacked relevant lift-design experience, testing, peer review, or industry support for the design change | Court: Excluded alternative-design testimony under Daubert/Schafersman as unreliable and not within his demonstrated expertise |
| Applicability of malfunction (indeterminate defect) theory to prove manufacturing defect | Plaintiffs argued malfunction theory permits circumstantial proof when specific defect evidence is lacking | Genie argued plaintiffs alleged specific design defects and thus cannot invoke malfunction theory | Court: Malfunction theory applies to strict liability generally but is unavailable where plaintiffs allege specific defects (O’Brien); court refused to apply it here |
| Whether admitted portions of Boye’s testimony created triable issues on manufacturing defect | Boye asserted a circuitry flaw caused the malfunction and cited post-sale evidence of malfunction and poor wiring | Genie emphasized alternative, non-manufacturing causes (repairs, taped button, component failure) and lack of pre-sale defect proof | Court: Admitted opinions still did not establish that a manufacturing defect at time of sale more likely than not caused the accident; summary judgment proper |
