Recent successes in strategic glyphosate litigation may prompt Bayer to push for a US Supreme Court ruling that federal law supersedes conflicting state law requiring glyphosate-based products to carry warnings of cancer risks on their labels. During the registration of Roundup weedkiller, the Environmental Protection Agency approved product labelling omitting a cancer warning under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Bayer accepts that current claims may be settled where there is an economic advantage. However, the company publicly states that "a favorable [sic] ruling by the US Supreme Court on the federal pre-emption question could largely end the Roundup litigation".
