Monsanto Co. v. Durnell — SCOTUS (argued April 27, 2026)
The Supreme Court considers whether federal pesticide law blocks a Missouri failure-to-warn verdict over Roundup. John Durnell said about twenty years of using the herbicide caused his non-Hodgkin's lymphoma, and a jury found Monsanto should have added a cancer warning. The EPA had approved Roundup's label without one. FIFRA, the Federal Insecticide, Fungicide, and Rodenticide Act, treats a pesticide as misbranded if its label is false, misleading, or omits a necessary health warning. Preemption means federal law displaces conflicting state law. Monsanto says FIFRA bars Missouri from imposing an extra warning and federal rules prevented it from adding one without EPA approval. Durnell says registration is only rebuttable evidence of compliance, so a parallel state claim may proceed. The Court later reversed, seven to two, holding FIFRA expressly preempted Durnell's claim.
