881 F.3d 658
8th Cir.2018Background
- Jones Stephens sold and a contractor installed a PlumBest stainless-steel braided toilet supply line (with a plastic coupling nut) at an Apex-owned building in 2004–2005.
- In January 2013 the plastic coupling nut fractured at its base/thread junction, causing a water leak and property damage.
- Apex’s expert opined the coupling nut was improperly manufactured because the plastic contained voids and testified that industry knowledge about void formation predated 2004.
- Apex sued Jones Stephens in Arkansas state law claims (strict liability, negligence, negligent failure to warn, deceptive trade practices, etc.); the district court granted summary judgment for Jones Stephens.
- On appeal (diversity jurisdiction), the Eighth Circuit reviewed de novo and affirmed, finding insufficient evidence to support Apex’s theories.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Strict liability: was the product "unreasonably dangerous"? | The supply line (plastic coupling nut) failed due to manufacturing defects (voids) and thus was unreasonably dangerous beyond ordinary contemplation. | An ordinary consumer would contemplate possible leaks or failures over time from plastic plumbing components; the failure is not beyond consumer contemplation. | Affirmed dismissal — Apex failed to show the danger was beyond what an ordinary, reasonable user would expect. |
| Negligence (design/manufacture): did Jones Stephens breach a duty? | Jones Stephens should have known voids can form in coupling nuts and should have prevented them. | Even if Jones Stephens should have known void formation was possible, there is no evidence it knew voids would cause structural failure (causation). | Affirmed dismissal — absent evidence linking voids to part failure, causation/speculation problem defeats negligence claim. |
| Negligent failure to warn: did Jones Stephens have a duty to warn Apex of the risk? | Jones Stephens should have warned users about risk of voids leading to failure. | No evidence Jones Stephens knew that voids would cause failure or that Apex relied on any warnings; no foreseeability/causal link. | Affirmed dismissal — no evidence Jones Stephens should have foreseen voids causing this failure. |
| Deceptive Trade Practices (ADTPA): did the "Leak proof" label cause Apex's damage? | The label "Leak proof seal" was deceptive; Apex relied on it and suffered damage. | Apex did not read or rely on the label before the incident; ADTPA requires that the deceptive practice cause the injury. | Affirmed dismissal — insufficient evidence of reliance/causation under the ADTPA as applied pre-2017 amendment. |
