Supreme Court Narrows Roundup Cancer Claims, Shifting Warnings to EPA

The Supreme Court, in a 7-2 ruling, limited thousands of state lawsuits alleging Roundup caused cancer by holding that only the EPA can require warning labels, effectively preempting state actions. The decision follows reporting on Monsanto ghostwriting studies used in regulatory assessments; plaintiffs can press the EPA to reevaluate, but thousands of cases remain and billions have already been paid in settlements as investigations into the ghostwriting continue.
