Case Explained: LYNNETTE J. KAISER v. ALCOA USA CORP., et al

Court: United States Court of Appeals for the Seventh Circuit Filed: 2026-08-14 The seventh-circuit affirmed the district court’s order certifying a class action under Federal Rule of Civil Procedure 23(b)(2) but reversed the grant of partial summary judgment in favor of the plaintiffs on the merits of their claims for lifetime retiree healthcare benefits. Regarding class certification, the court held that the district court did not abuse its discretion in finding commonality and typicality under Rules 23(a)(2) and 23(a)(3). The court reasoned that although the collective bargaining agreements (CBAs) were silent regarding the duration of retiree healthcare benefits, the plaintiffs proffered common objective evidence—specifically testimony from Alcoa’s lead labor negotiator stating he believed the company could not unilaterally alter benefits for pre-1993 retirees and the company’s historical conduct—to demonstrate a latent ambiguity sufficient to rebut the presumption against vesting. The court further determined that Rule 23(b)(2) was appropriate because the primary relief sought was declaratory and injunctive, with any monetary damages being incidental to the determination of the class-wide contractual rights. Regarding the summary judgment ruling, the court reversed based on its application of the equitable doctrine of judicial estoppel. The district court had granted summary judgment by estopping Alcoa from denying vested lifetime benefits because statements made by the company in prior litigation (*Curtis v. Alcoa, Inc.*) appeared to contradict its current position. The appellate court found that the prior statements were not clearly inconsistent with Alcoa’s present stance. The court noted that *Curtis* concerned post-1993 retirees subject to a benefit cap, whereas this case involves pre-1993 retirees; Alcoa’s references to “lifetime” benefits in *Curtis* were conditional or specific to the capped group and did not constitute an unambiguous admission regarding the uncapped rights of the pre-1993 class. Consequently, the court held that judicial estoppel did not apply and remanded the case for further proceedings consistent with this opinion, leaving it to the district court’s discretion to determine whether to conduct a new summary judgment analysis or proceed to trial.
