Laura Revolinsky v. Bayer Corporation: Date Argued: February 13th, 2026; Docket Number: 25-2401

Case Summary:In the case of Laura Revolinsky v. Bayer Corporation (Docket No. 25-2401), argued before the U.S. Court of Appeals for the Seventh Circuit on February 13, 2026, the relevant facts are as follows:The litigation is a class action lawsuit involving allegations that Seresto flea and tick collars, developed by Bayer and sold by Elanco Animal Health, were defectively designed and caused significant harm or death to thousands of pets.The plaintiff, Laura Revolinsky, is one of the lead representatives for a certified class of consumers who purchased the collars based on representations that the product was safe for dogs and cats.A central factual element of the case is the combination of two pesticides, imidacloprid and flumethrin, which the plaintiffs allege create a toxic effect that was not adequately disclosed to consumers or regulators.The factual record includes more than 75,000 incident reports submitted to the EPA since 2012, including approximately 1,700 reported pet deaths and nearly 1,000 reports of human harm, such as skin rashes and neurological symptoms.The defendants maintain that the collars are safe when used as directed and that the reported incidents do not establish a scientific causal link between the product and the alleged injuries.The case follows a $15 million class action settlement that was preliminarily approved in 2024; however, the current appeal focuses on a July 25, 2025, district court order regarding the scope of the class or the fairness of the final distribution.The appellate record examines whether the district court erred in its certification of the class or in its handling of objections from class members who claimed the settlement amount was insufficient given the scale of the alleged veterinary expenses.During the oral arguments on February 13, 2026, the Seventh Circuit panel scrutinized whether the district court properly applied the standards for "adequacy of representation" for the diverse group of pet owners included in the settlement.
