942 F.3d 401
8th Cir.2019Background
- Emerson (Missouri corp.) designs, markets, and sells RIDGID vacuums from Missouri and advertises their "peak horsepower," which is achievable only in lab conditions, not in typical home use.
- Plaintiffs sued claiming the peak-horsepower advertising is misleading, asserting MMPA claims, breach of express and implied warranty, unjust enrichment, various state consumer-protection claims, and a Louisiana redhibition subclass.
- The MDL panel consolidated related suits; after discovery plaintiffs moved to certify a nationwide class and the district court applied Missouri choice-of-law rules, concluding Missouri law governed all claims and certifying the class under Fed. R. Civ. P. 23(b)(3).
- Emerson appealed, arguing the MMPA does not reach out-of-state transactions and the court failed to perform separate choice-of-law analyses for the contract/unjust-enrichment claims.
- The Eighth Circuit reversed and remanded: it held that the district court erred in applying the MMPA to nationwide transactions (aligning the case with Perras) and failed to perform individualized choice-of-law analyses for the other claims.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Applicability of MMPA to out-of-state class members | Missouri law governs because Emerson’s advertising was designed and controlled in Missouri | MMPA applies only to commerce "in or from" Missouri; out-of-state purchases occurred in purchasers' home states | Reversed: MMPA does not cover those out-of-state transactions where only ad design occurred in Missouri (case like Perras) |
| Choice-of-law for breach of warranty and unjust enrichment | A single Missouri-law choice suffices for all claims | Different conflicts tests apply to tort (MMPA), contract, and unjust enrichment; court must analyze each claim separately | Reversed/remanded: district court failed to conduct individualized, claim-specific choice-of-law analyses |
| Rule 23(b)(3) predominance for a nationwide class | Common issues (advertising, representations) predominate | Variations in state laws will swamp common issues and defeat predominance | Remanded: unresolved choice-of-law issues prevent affirming nationwide class certification; court did not resolve predominance on the merits |
| Other class-certification challenges (Daubert, expert, adequacy) | Certification appropriate | District court erred on expert reliability and adequacy | Not decided: appellate court declined to reach these arguments pending proper choice-of-law analysis |
