Court rules for Roundup maker in dispute over cancer warnings on pesticide labels

The Supreme Court ruled 7-2 in favor of Monsanto, holding that state lawsuits against the company for failing to warn consumers about Roundup's potential cancer risks are preempted by federal pesticide labeling laws. The majority opinion by Justice Brett Kavanaugh emphasized that the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) bars states from imposing additional labeling requirements beyond those approved by the EPA, while Justice Ketanji Brown Jackson dissented, arguing the ruling creates a non-existent labeling requirement.
