Gina Glazer and Trina Allison, Ohio purchasers of Whirlpool Duet front-loading washing machines, brought a proposed consumer class action alleging that the machines shared a design defect. According to the plaintiffs, the machines did not adequately clean internal components, allowing residue known as biofilm to accumulate and promote mold, mildew, bacteria, foul odors, and damage to laundry. They also alleged that Whirlpool knew of this propensity but inadequately warned consumers.
The plaintiffs’ evidence included Whirlpool internal documents showing that engineers had identified residue buildup and mold issues across the relevant Duet platforms, despite differences in consumer laundry habits. Whirlpool maintained that mold was rare, that the models and consumers’ usage patterns materially differed, and that owners without a manifested mold problem had suffered no injury.
The multidistrict-litigation court certified an Ohio liability class under Rules 23(a) and 23(b)(3) for claims of tortious breach of warranty, negligent design, and negligent failure to warn. It declined to certify a consumer-protection claim and reserved damages for individual proceedings. The Sixth Circuit initially affirmed. After the Supreme Court granted certiorari, vacated the judgment, and remanded for reconsideration in light of Comcast Corp. v. Behrend, Whirlpool sought a further remand to the district court.
Issue #1
Whether the Supreme Court’s grant-vacate-remand order required the Sixth Circuit to remand the case to the district court for initial consideration of Comcast.
Holding
No. The Sixth Circuit could reconsider its own class-certification ruling directly and denied Whirlpool’s motion to remand.
Reasoning
A grant-vacate-remand order is not a merits reversal and does not signal that the Supreme Court believes the prior result was wrong. It directs the lower court to consider whether the intervening authority changes the result.
Unlike cases in which a new Supreme Court decision required the district court to exercise discretion or make initial factual determinations, this remand required only reconsideration of the appellate court’s Rule 23 analysis in light of Comcast. The Sixth Circuit therefore retained an adequate basis to decide the question itself.
Issue #2
Whether the district court conducted the rigorous Rule 23 analysis required at the class-certification stage, including an appropriate consideration of merits-related evidence.
Holding
Yes. The district court properly considered merits issues to the extent they bore on the Rule 23 requirements.
Reasoning
Rule 23 requires a rigorous analysis, and that analysis may overlap with the merits when merits questions are relevant to certification. But a court may not conduct a free-ranging inquiry that turns certification into a trial on the merits.
Although the district court had cited older language suggesting that a merits inquiry was not required, its actual process was sufficient. It reviewed extensive corporate records, expert and witness affidavits, evidentiary submissions, and oral argument; it also allowed Whirlpool to present live testimony, which Whirlpool ultimately chose not to offer.
The district court evaluated the evidence relevant to the proposed claims, denied certification on one claim, and certified only a liability class while reserving damages. That approach satisfied the rigorous-analysis requirement without prematurely resolving ultimate liability.
Issue #3
Whether the proposed Ohio purchaser class satisfied Rule 23(a), particularly numerosity, commonality, typicality, and adequate representation.
Holding
Yes. The district court did not abuse its discretion in finding that all four Rule 23(a) requirements were met.
Reasoning
Numerosity was readily established because Whirlpool shipped many thousands of the relevant machines to Ohio for retail sale, making joinder of all affected purchasers impracticable. Whirlpool did not meaningfully dispute this point.
The central common questions were whether shared design defects in the Duet machines caused biofilm, mold, or mildew growth, and whether Whirlpool adequately warned consumers about that propensity. Answers to those questions would resolve issues central to each class member’s design-defect, warranty, and failure-to-warn claims.
The fact that the machines encompassed different models and two engineering platforms did not defeat commonality. The plaintiffs’ evidence, including Whirlpool’s own internal materials, supported the conclusion that the platforms were nearly identical in the relevant respects and that the alleged residue-and-mold problem extended across them. Differences in styling and limited functions did not eliminate the common alleged defect.
Variations in consumers’ laundry practices also did not require individual causation trials at the certification stage. Whirlpool’s internal evidence indicated that mold growth occurred under varied household conditions, while plaintiffs’ expert explained that consumer practices could affect the amount of biofilm but were not its underlying cause. The common issue remained whether the machines’ design created the propensity for biofilm and mold.
The class could include purchasers whose machines had not yet manifested a mold problem. Under the plaintiffs’ theory, every purchaser was injured at sale by paying for a product allegedly worth less because of its common defect and by receiving inadequate warnings. Whether a particular purchaser later suffered additional losses went to individual damages, not to the existence of the common liability questions.
Glazer and Allison were typical and adequate representatives because they bought the same kinds of machines for ordinary household use and asserted the same theory as the class: that Whirlpool sold defectively designed machines without adequate warnings. Their own experiences with mold did not make them adverse to purchasers whose losses had not yet manifested, because both groups relied on the same alleged point-of-sale injury.
Issue #4
Whether common issues predominated and a class action was superior under Rule 23(b)(3).
Holding
Yes. Common liability questions predominated over individual issues, and a liability-only class action was the superior method of adjudication.
Reasoning
Under Amgen, predominance asks whether common questions can be proved with common evidence, not whether the plaintiffs have already proved that they will win those questions. If the alleged design defect or warning failure could not be proved, the class would fail together; that failure would not create a set of individual issues that defeated predominance.
The common proof in this case would establish or disprove, for the class as a whole, whether the alleged design features caused residue and mold growth and whether Whirlpool had a duty to warn that it breached. Whirlpool identified no material class-member dissimilarity that would make representative adjudication unfair or inefficient.
Comcast did not require a different result. Comcast rejected certification of a combined liability-and-damages antitrust class because the plaintiffs’ damages model did not measure damages attributable solely to the one antitrust theory the district court had allowed. Here, by contrast, the district court certified a liability-only class and expressly reserved damages for individual determination.
Comcast reaffirmed that certification cannot evade Rule 23’s requirements, but it did not discard the established rule that individualized damages calculations do not bar certification when common liability questions predominate. Rule 23(c)(4) permits liability issues to be resolved on a classwide basis while damages are addressed later.
A class action was also superior because the likely cost of individual litigation would exceed the potential recovery for most purchasers. Without class treatment, the realistic alternative was likely no litigation at all. Class members retained the opportunity to opt out and pursue their own claims if they preferred.
