Supreme Court Weighs Bayer Roundup Cancer Case That Could End 100,000 Lawsuits

The U.S. Supreme Court heard oral arguments in a case brought by Bayer AG concerning its Roundup weedkiller, which faces over 100,000 lawsuits alleging the product causes cancer. At issue is whether the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) preempts state-law failure-to-warn claims. A ruling in favor of Bayer could effectively gut the vast majority of pending litigation. The case stems from a lawsuit by a California groundskeeper who developed non-Hodgkin lymphoma after years of using Roundup. The justices' decision, expected by late June, will have major implications for product liability law and the regulation of pesticides.
