Judith Wurster v. The Plastics Group
917 F.3d 608
8th Cir.2019Background
- Mr. James Wurster died after a Wedco Model W520 gas can manufactured by The Plastics Group, Inc. (TPG) exploded while he was burning trash; vapors ignited and the can detonated.
- The can had a front nozzle with a mesh flame arrester but an unprotected rear vent hole; experts disagreed which opening he used to pour gasoline.
- By 2000 many competitors used flame arresters and a basket-type arrester could have been added for minimal cost; TPG later revised warnings on new cans but provided no post-sale warnings to past purchasers.
- Mrs. Wurster sued TPG for negligence (design defect and failure to warn); the district court submitted the case to a jury on negligence theories and granted JMOL on a post-sale failure-to-warn claim.
- The jury found no defectively designed can but found inadequate warnings and apportioned fault: TPG 45%, Mr. Wurster 55%; under Iowa comparative fault (Iowa Code § 668.3(1)) judgment was entered for TPG.
- Mrs. Wurster appealed, challenging jury instructions (design-defect instruction refusal; reasonable-alternative-design instruction; dual assumption-of-risk instructions) and the JMOL on post-sale warning.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Refusal to give strict-products-liability design-defect instruction | Wurster: court should have given Iowa CJI 1000.2 (strict products-liability formulation) | TPG: Iowa law treats design-defect as negligence; cannot submit negligence and strict liability for same design theory | Affirmed — court properly refused because instruction conflicted with Iowa law and design-defect was submitted as negligence |
| Giving reasonable-alternative-design instruction without CJI 1000.2 | Wurster: cannot give 1000.4 factors absent 1000.2; causes confusion | TPG: factors appropriate to guide jury on negligence/risk-utility | Affirmed — court may mix instructions; 1000.4 was proper to guide negligent-design (risk-utility) analysis |
| Inclusion of assumption-of-risk both in comparative-fault instruction and as separate instruction | Wurster: dual treatment violates Coker and unduly emphasizes plaintiff fault | TPG: instruction defined elements and allowed apportionment of fault | Affirmed — although imperfectly worded, no prejudice; dual use served as definitional guidance and did not impair plaintiff's case |
| JMOL on post-sale failure-to-warn claim | Wurster: TPG knew explosion risk and should have warned prior purchasers | TPG: lacked ability to identify or warn individual purchasers; could not reasonably provide post-sale warnings | Affirmed — insufficient evidence of ability to identify/notify purchasers; no post-sale duty as matter of law under Restatement (Third) §10 factors |
