Roundup at the Supreme Court: Durnell Decision Pending as a $7.25B Class Settlement Advances
Two developments could reshape the Roundup litigation at once. The U.S. Supreme Court is poised to decide whether federal pesticide law preempts state-law failure-to-warn claims, and a separate proposed $7.25 billion class settlement for future claims is moving through a Missouri court over the MDL judge's objections.
Key Takeaways
- The Supreme Court heard argument in Monsanto v. Durnell on April 27, 2026 (FIFRA preemption of failure-to-warn claims); a decision is expected by the end of the term and had not yet issued as of late June
- A separate proposed $7.25 billion class settlement (King v. Monsanto) for current and future NHL claims received preliminary approval in March 2026 and is contested
- After a removal fight, the King case was remanded to Missouri state court in June 2026, where approval proceedings continue
- Roughly 65,000 claims remain nationwide; about 3,900 are in the federal MDL before Judge Chhabria
- Bayer has paid more than $10 billion resolving prior Roundup claims since 2020
The Supreme Court case: Monsanto v. Durnell
The Court granted review in January 2026 and heard oral argument on April 27, 2026. The question is whether the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) preempts state-law claims that Monsanto failed to warn that Roundup can cause non-Hodgkin lymphoma. A ruling for Monsanto could foreclose many failure-to-warn claims nationwide; a ruling the other way would let them proceed. As of late June 2026 no opinion had issued, and a decision is expected before the term ends. It is the single most consequential pending event for the litigation.
The $7.25 billion King v. Monsanto class settlement
Separately, a proposed class settlement reported at up to $7.25 billion over roughly 21 years would resolve current and future NHL claims. It received preliminary approval in a Missouri state court in March 2026 but is contested — it has drawn formal objections, and MDL Judge Vince Chhabria has been openly critical of it. After a federal removal fight, the case was remanded to Missouri state court in June 2026, where approval proceedings continue. Its ultimate path is unsettled, and it is a second attempt at a future-claims class structure after the 2021 fund Judge Chhabria rejected.
