On Monday, the Supreme Court heard oral arguments in Monsanto Company v. Durnell, a case that will determine the balance of power between states and the federal government over cancer warnings on pesticide labels.
In 2019, the defendant, John Durnell, filed a lawsuit against Monsanto Co., arguing that he had developed non-Hodgkin's lymphoma due to exposure to glyphosate, an active ingredient in the company's weed killer Roundup. In 2023, a jury sided with Durnell, awarding him $1.25 million after it found Monsanto liable for failing to warn of the alleged cancer risk from glyphosate, even though the Environmental Protection Agency (and several other studies) have not found a link between glyphosate and higher cancer rates.
