Key Takeaways
- • Consumer class action plaintiffs are petitioning the Ninth Circuit Court of Appeals to recover attorney fees in their challenge to Kroger's abandoned $24.6 billion acquisition of Albertsons, arguing they substantially prevailed despite the deal's collapse.
- • Plaintiffs' counsel contends the lower court erred in determining the case was mooted by separate federal actions blocking the merger, asserting their class action was instrumental in preventing the transaction.
- • The fee petition hinges on a legal determination of "substantial prevailing party" status—a threshold that would entitle plaintiffs to recover legal costs despite the underlying merger being terminated through other regulatory intervention.
- • The case centers on whether consumer litigation directly contributed to the merger's failure or whether independent federal enforcement actions were the decisive factor in blocking the $24.6 billion deal.
Summary
Consumer plaintiffs in a class action lawsuit challenging Kroger's $24.6 billion proposed acquisition of Albertsons are seeking attorney fees at the Ninth Circuit Court of Appeals following the merger's abandonment. On May 19, 2026, counsel for the grocery store consumers argued before the appellate court that their clients substantially prevailed in the litigation and are entitled to recover legal expenses, despite the lower court's determination that the case was rendered moot by other federal actions blocking the transaction.
The core dispute centers on causation and the proper legal standard for awarding attorney fees in merger-challenge litigation. Plaintiffs' counsel contends that the lower court incorrectly concluded the case became moot after separate federal enforcement actions resulted in the deal's termination. According to the filing, the consumers' class action played a material role in compelling Kroger to abandon the merger, and therefore the plaintiffs should qualify as "substantially prevailing parties" entitled to recover their legal costs under applicable fee-shifting provisions.
The "substantial prevailing party" doctrine is a critical mechanism in consumer and antitrust litigation, allowing plaintiffs who achieve significant policy or injunctive victories—even without monetary recovery—to offset legal expenses. The Ninth Circuit's determination on this issue will affect how courts evaluate causation in merger-challenge cases where multiple parties (including federal agencies) pursue overlapping objectives to block a transaction.
This appellate decision carries implications for future consumer-initiated antitrust challenges, as it will clarify whether plaintiffs must demonstrate their litigation was the sole or primary factor driving a merger's failure to qualify for fee recovery, or whether material contribution to a deal's abandonment is a sufficient standard.
