Third Circuit Rejects “Reasonable Indication” Opt-Out Standard
The Third Circuit recently rejected the so-called “reasonable indication” opt-out standard, which refers to whether a class member can opt out of a class action by merely providing a “reasonable indication” of their intent to do so, regardless of whether this indication adheres to the letter of the procedures established by the district court. See Perrigo Institutional Investor Group v. Papa, No. 24-2861, 2025 WL 2315977 (3rd Cir. Aug. 12, 2025).
Appellants inadvertently failed to opt out of class membership in a securities-related class action. This failure came to light on the eve of settlement in parallel litigation, which was premised on the erroneous assumption that Appellants had properly opted out. On appeal, Appellants urged the Third Circuit to adopt the “reasonable indication” standard and conclude the separate litigation was sufficient evidence of their intention to opt out of the class. The Third Circuit declined to do so, reasoning that it was contrary to the text of Rule 23 and that it would complicate administrability of class membership opt-outs.Continue Reading Third Circuit Rejects “Reasonable Indication” Opt-Out Standard
Ninth Circuit Affirms Class Certification Based on Unexecuted Damages Model
Extending its recent decision in Lytle v. Nutramax Laboratories, Inc., 114 F.4th 1011, 1032 (9th Cir. 2024), the Ninth Circuit recently affirmed class certification in a false advertising case based in part on an unexecuted and “not yet fully developed” damages model. The panel reasoned that the expert’s explanation of the damages model he proposed to (but had not yet) run established that the model “could reliably measure damages on a classwide basis and adequately for present purposes matched [plaintiff’s] theory of harm.” The panel also confirmed that in some cases, false advertising plaintiffs can benefit from an inference of classwide materiality and reliance under California law.Continue Reading Ninth Circuit Affirms Class Certification Based on Unexecuted Damages Model
Illinois Federal Court Permits Citric Acid Case To Proceed
A court in the Northern District of Illinois recently denied a motion to dismiss a lawsuit alleging that the alleged inclusion of artificial citric acid in a product rendered the “No Artificial Flavors, Preservatives, or Dyes” representation on the front label false and/or misleading. Hayes v. Kraft Heinz Co., 2024 WL 4766319 (N.D. Ill. Nov. 13, 2024). Continue Reading Illinois Federal Court Permits Citric Acid Case To Proceed
Ninth Circuit Further Refines Rule on When Back Labels Should Be Considered in False Advertising Claims
Last year, in an important decision for companies that routinely face false advertising claims, the Ninth Circuit held that when “a front label is ambiguous, the ambiguity can be resolved by reference to the back label.” McGinity v. Procter & Gamble Co., 69 F.4th 1093, 1099 (9th Cir. 2023). The Ninth Circuit recently further clarified when reference to the back label is appropriate. See Whiteside v. Kimberly Clark Corp., 108 F.4th 771 (9th Cir. 2024).Continue Reading Ninth Circuit Further Refines Rule on When Back Labels Should Be Considered in False Advertising Claims

Ninth Circuit Confirms Courts Should Consider Whether Back Panel Disclosures Help Clarify Ambiguous Front-of-Pack Claims
The Ninth Circuit recently issued an important decision for consumer companies that routinely face false advertising litigation. Resolving an issue that had split district courts in the circuit, the panel held that when “a front label is ambiguous, the ambiguity can be resolved by reference to the back label.” McGinity v. Procter & Gamble Co.,– F.4d –, 2023 WL 3911531, at *4 (9th Cir. June 9, 2023). The court also issued a memorandum affirming the dismissal of a complaint against Icelandic Provisions on the same grounds; Covington represented the company in that matter. See Steinberg v. Icelandic Provisions, Inc., 2023 WL 3918257, at *1 (9th Cir. June 9, 2023). With these decisions, the Ninth Circuit joins the growing consensus that back labels must be considered when a challenged front label claim is ambiguous. See, e.g., Foster v. Whole Foods Mkt. Grp., Inc., 2023 WL 1766167, at *3 (E.D.N.Y. Feb. 3, 2023).Continue Reading Ninth Circuit Confirms Courts Should Consider Whether Back Panel Disclosures Help Clarify Ambiguous Front-of-Pack Claims
