The U.S. Supreme Court has ruled in favor of Bayer, dismissing thousands of lawsuits alleging that its glyphosate-based products caused cancer. The decision effectively removes the legal basis for claims arguing Bayer failed to adequately warn consumers about potential health risks. Plaintiffs had argued that Bayer’s Roundup weedkiller caused non-Hodgkin’s lymphoma, and sought billions in damages. The court found that federal law preempts state law claims relating to the labeling of agricultural chemicals when the label has been approved by the Environmental Protection Agency (EPA). This ruling significantly limits the ability of plaintiffs to sue over glyphosate’s alleged cancer risks, potentially shielding Bayer from further substantial financial liabilities. The decision impacts a large number of ongoing and future cases concerning the herbicide.
