Filing with the U.S. Supreme Court: Questions and Answers 

On February 23, 2026, Monsanto filed its opening brief with the U.S. Supreme Court in Durnell, a case that will address the split in authority among federal circuit courts on whether the “uniformity” provision of FIFRA preempts state-based claims grounded in failure-to-warn-theories that EPA has not required, a cross cutting issue in the Roundup™ litigation. A favorable outcome would contribute to significantly containing the Roundup™ litigation – including any opt-outs from the recently announced class settlement. The case will be argued on April 27, and the company anticipates a decision on the merits during the Court’s 2026 term, which concludes in June.
