Monsanto is asking for a second shot at convincing a federal appeals court to block claims from a Georgia landowner who says he developed a rare form of cancer after years of using Roundup weedkiller.

The company’s petition for rehearing, filed Monday in the 11th U.S. Circuit Court of Appeals, could also set the stage for a Supreme Court battle to relieve Monsanto from thousands of similar claims from Roundup users nationwide.

In a ruling earlier this month, the 11th Circuit rejected Monsanto’s argument that the Federal Insecticide, Fungicide and Rodenticide Act blocked a state-level claim from John Carson that Monsanto had failed to warn customers about the health risks of using Roundup.


Monsanto, which is now owned by Bayer, argued that EPA had already determined a warning was not necessary.
