Supreme Court’s 2026 Monsanto v. Durnell Ruling: Federal Preemption Shields Bayer from Thousands of Glyphosate Lawsuits
Overview
On June 25, 2026, the U.S. Supreme Court issued a landmark decision in Monsanto Co. v. Durnell, focusing on federal preemption. The Court ruled that federal law, specifically the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), gives the EPA exclusive authority to approve and regulate pesticide labels. Monsanto (Bayer) successfully argued that because the EPA had approved its product labels, state-level 'failure-to-warn' claims could not proceed. This decision provides strong legal support for manufacturers using preemption defenses, significantly strengthening their position against similar lawsuits and reshaping the landscape of product liability litigation.
