The Supreme Court on Thursday sided with Monsanto in a high-stakes dispute over cancer warnings on pesticide labels. In an by Justice Brett Kavanaugh in Monsanto Company v. Durnell<\/em>, the court ruled, by a vote of 7-2, that state lawsuits aimed at holding the company liable for failing to warn consumers about the potential risks of Roundup exposure are barred by the federal law governing pesticide sales.<\/p>\n

Justice Ketanji Brown Jackson wrote a dissenting opinion, joined by Justice Neil Gorsuch. In it, she contended that Thursday\u2019s ruling is based on \u201ca labeling requirement that does not exist,\u201d and described the effects of the majority\u2019s interpretation of the law as \u201cboth remarkable and regrettable.\u201d<\/p>\n

The court\u2019s ruling comes after decades of debate and litigation over the safety of glyphosate, a highly effective and popular herbicide that serves as the main active ingredient in Monsanto\u2019s Roundup weedkiller. Since 1974, when the Environmental Protection Agency first reviewed and registered glyphosate-based pesticides, clearing the way for their sale in the United States, the EPA has repeatedly concluded that such products do not need to carry a cancer warning. However, the EPA\u2019s determinations have not dispelled concerns about Roundup\u2019s cancer risks. These concerns increased in 2015, when a working group of the International Agency for Research on Cancer, part of the World Health Organization, classified glyphosate as \u201cprobably carcinogenic to humans.\u201d<\/p>\n

The IARC\u2019s report led to tens of thousands of lawsuits against Monsanto over how Roundup products were labeled. Plaintiffs such as John Durnell, who brought the case that was before the court, contended that the company was liable for failing to warn them about the alleged link between glyphosate and cancer, while Monsanto countered that the EPA, which oversees pesticide labeling, had not required a cancer warning.<\/p>\n

Over the past decade, Monsanto has paid billions in damages and settlement agreements in these lawsuits even as it has continued to assert that state-level claims over Roundup labels are preempted by the Federal Insecticide, Fungicide, and Rodenticide Act, which authorizes the EPA to regulate the use, sale, and labeling of pesticides and which includes a uniformity requirement prohibiting states from imposing \u201cany requirements for labeling or packaging in addition to or different from those required\u201d by the federal government.<\/p>\n

When it the Supreme Court to clarify the scope of FIFRA, Monsanto emphasized that thousands of lawsuits over Roundup\u2019s label remain pending and claimed that the future of U.S. agriculture was at stake in the case. In January, the justices agreed to weigh in.<\/p>\n

On Thursday, the court held that FIFRA expressly preempts a state-law failure-to-warn claim against Monsanto, because such a claim would require the company \u201cto add a cancer warning to Roundup\u2019s label\u201d that is not part of the EPA-approved label. That outcome, Kavanaugh wrote, runs afoul of FIFRA\u2019s uniformity requirement.<\/p>\n

Kavanaugh also noted that the EPA has repeatedly assessed the safety of glyphosate-based pesticides and \u201crepeatedly concluded that glyphosate is not likely to cause cancer.\u201d \u201cTherefore, as a matter of federal law,\u201d Kavanaugh wrote, \u201cMonsanto legally must use a label without a cancer warning unless and until EPA approves or requires a change.\u201d<\/p>\n

In her 24-page dissent, Jackson wrote that the court should have joined the \u201cchorus\u201d of \u201cstate and federal courts that have rejected this preemption argument,\u201d asserting that FIFRA gives the EPA the authority to review product labels when assessing pesticides, but not the authority to have the final say on cancer warnings. \u201cIn accepting Monsanto\u2019s argument and holding that Durnell\u2019s failure-to-warn claim is preempted, the Court misunderstands FIFRA\u2019s requirements, misinterprets the scope of FIFRA\u2019s preemption, and ultimately leaves Durnell without a remedy for the significant harms he has suffered,\u201d she wrote.<\/p>\n
