Bayer shares soar 11% after key U.S. legal win against Roundup cancer claims
Bayer shares jumped in morning trade as the German life sciences company said it scored a legal victory in its suit over claims that exposure to its popular Roundup weed killer led to cancer.

Writing for a three-judge panel, Chief Judge Michael Chagares said that the Federal Insecticide, Fungicide, and Rodenticide Act demands uniformity of state law labeling requirements, preventing the obligation to add a cancer warning to Roundup in Pennsylvania in this case.
Chip Becker, a lawyer for the Schaffners, expressed disappointment in the court decision and said that federal law should not preempt the failure-to-warn claim of his clients, who will review their legal options, according to Reuters.

On Thursday, Bayer noted that the Philadelphia ruling conflicts with decisions made by other federal
