Bayer (BAYGn.DE) said on [April 4, 2025] it was again petitioning the U.S. Supreme Court to sharply limit legal claims that its Roundup weedkiller causes cancer, seeking to avoid potentially billions of dollars in damages.
Bayer said in its petition that consumers should not be able to sue it under state law for failing to warn that Roundup increases cancer risk because the U.S. Environmental Protection Agency has found no such risk and requires no such warning. In fact, it argued, federal law does not allow it to add any warning to the product beyond the EPA-approved label.
The company has paid about $10 billion to settle claims that Roundup, based on the herbicide glyphosate, causes cancer. About 67,000 further cases are pending, for which the group has set aside $5.9 billion in legal provisions.

The company has warned U.S. lawmakers it could stop selling Roundup, which is widely used by U.S. farmers, unless they can strengthen legal protection against the litigation.
