78 F.4th 677
4th Cir.2023Background
- In 2018 Marriott disclosed a data breach of the Starwood guest reservation database affecting ~133.7 million U.S. records; plaintiffs filed consolidated MDL actions including claims against Marriott and Accenture (IT vendor).
- Plaintiffs asserted state-law contract and consumer-protection claims against Marriott and negligence claims against Marriott and Accenture; MDL in D. Md.; bellwether plaintiffs selected by state.
- District court certified three state-specific Rule 23(b)(3) damages classes against Marriott (limited to SPG members after typicality/standing concerns) and four state-specific Rule 23(c)(4) negligence "issue" classes (duty and breach only) against Marriott and Accenture.
- The district court limited classes to SPG (Starwood Preferred Guest) members because class reps had signed SPG Terms & Conditions containing a class-action waiver, but declined to resolve the enforceability/timing of the waiver at certification, saying it could be addressed later.
- Disting. rulings: district court accepted an expert overpayment model for classwide damages on the overpayment theory (Daubert ruling) and rejected a market-value damages model for negligence; it nonetheless certified issue classes on duty/breach and left injury/causation/damages for individualized proceedings.
- Fourth Circuit vacated the entire certification order and remanded because the district court erred by certifying classes composed entirely of SPG members without first resolving the class-action waiver; that error also undermined the Rule 23(c)(4) superiority analysis for Accenture issue classes.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the district court could certify classes of SPG members without deciding the SPG class-action waiver | Plaintiffs: Marriott waived/repudiated the waiver or it is unenforceable; court could defer | Marriott: waiver bars class relief and must be resolved at certification to protect contractual bargain | Court: District court erred; class waivers must be addressed before certification; vacated and remanded |
| Whether a class-action waiver is a "merits" issue that may be deferred until after class certification | Plaintiffs: waiver is a merits/affirmative defense and can be resolved later | Marriott: waiver is not a merits defense to liability but bars class procedure and must be decided at certification | Court: Waiver is procedural re right to class relief; even if merit-linked, rigorous Rule 23 analysis requires resolving it pre-certification |
| Ascertainability / standing adjustments limiting classes to non‑reimbursed payors (overpayment theory) | Plaintiffs: limiting classes to persons who bore room costs fixes standing and keeps class ascertainable | Marriott: limiting creates administrability/ascertainability problems and heterogeneity | Court below found classes ascertainable and limited to non-reimbursed payors, but this issue was not resolved on appeal; appellate decision vacated certification on other grounds |
| Whether Rule 23(c)(4) issue classes (duty and breach) against Accenture satisfy Rule 23(b)(3) superiority given individualized injury/causation | Plaintiffs: issue certification is efficient because district court also certified Marriott damages classes; common duty/breach issues predominate | Accenture: superiority fails if Marriott damages classes are not certified; issue classes leave extensive individualized follow-on litigation | Court: Vacated issue-class certification because its superiority analysis depended on the now-vacated Marriott damages classes; remand for reconsideration |
