Supreme Court sides with Monsanto in Roundup labeling case
High court rules federal pesticide-labeling rules preempt state claims over Roundup’s cancer warning.
The U.S. Supreme Court reversed a Missouri Court of Appeals decision that had allowed state-law liability claims against Monsanto for failing to include a cancer warning on the label of its Roundup herbicide. The justices ruled that federal pesticide-labeling requirements preempt those state-law claims.
