Supreme Court Hears Roundup Warning Liability Fight Monday

The Supreme Court’s ruling could affect pesticide warning claims well beyond Roundup. Richard Gupton with the Ag Retailers Association joins us to explain the importance of federal pesticide labeling standards and discuss the potential impact on the ag industry and supply chain.

NASHVILLE, TENN. (RFD NEWS) — The U.S. Supreme Court will hear arguments Monday in a case that could affect pesticide lawsuits across agriculture. Brigit Rollins with the National Agricultural Law Center said the ruling could shape how failure-to-warn claims are handled for Roundup and other crop protection products.

In the case Durnell v. Monsanto, a Missouri man claims Roundup exposure caused his non-Hodgkin’s lymphoma. A jury awarded him $1.25 million, and Missouri courts allowed that verdict to stand.

Bayer, which owns Monsanto, argues the case should be blocked by federal law. The company says FIFRA gives the EPA authority over pesticide labeling and that states cannot impose warning requirements that differ from federal standards.

The plaintiff argues his claim can still move forward. He says federal law already bars misbranding and that his case also points to older marketing materials that described Roundup as safe.

The outcome could extend well beyond a single product. The Court’s decision may influence thousands of pending cases and help define how far federal pesticide law reaches when state courts hear product-warning disputes.

The Supreme Court is preparing to hear arguments in a case centered around the herbicide Roundup, one of thousands of lawsuits filed over the past decade, with a decision that could impact all crop protection products. Richard Gupton with the Agricultural Retailers Association (ARA) joined us on Monday’s Market Day Report to provide insight into the case and its potential broader implications on the agriculture industry as whole.

In his interview with RFD News, Gupton explained the crux of the case and discussed how the Federal Insecticide, Fungicide, and Rodenticide Act has governed pesticide labeling and use for decades, emphasizing the importance of uniform labeling standards. He also addressed how the case before the Supreme Court could impact that system and what could happen if national uniformity were to end.

Finally, Gupton outlined potential ripple effects across the ag supply chain and shared his outlook for the case going forward, including what the industry should consider ahead of the Court’s decision.
