Supreme Court ruling forces Bayer's Monsanto to seek $7.25B Roundup settlement

Bayer's Monsanto division appeared before Judge Timothy Boyer in St. Louis to request approval of a $7.25 billion settlement covering roughly 65,000 claims that Roundup caused cancer. The proceeding follows the Supreme Court's 7-2 ruling in Monsanto Co. v. Durnell, where Justice Brett Kavanaugh authored the majority opinion, joined by Roberts, Thomas, Sotomayor and Kagan, holding that the Federal Insecticide, Fungicide, and Rodenticide Act preempts state jury verdicts that impose labeling warnings beyond EPA requirements.

The decision stripped plaintiffs of their strongest failure-to-warn argument, leading attorney Hunter Shkolnik to note that many clients who had planned to pursue court action now support the settlement. EPA has repeatedly concluded glyphosate is unlikely to be carcinogenic, and the Court's reliance on the supremacy clause aims to ensure uniform pesticide labeling nationwide. While design-defect and testing claims remain viable, the ruling gives Bayer greater predictability and pressures mass-tort firms in future negotiations, affecting Bayer's litigation reserves now over €11 billion.
