The Supreme Court's Monsanto ruling works like this: if glyphosate's cancer risk isn't on the label, the EPA said there's no issue, so you can't sue for failure to warn. If it is on the label, you were warned, so you still can't sue.

"You can't bring a failure to warn claim in any state under any state law," @AaronSiri explained. "That is basically effectively immunity granted by the members of the US Supreme Court."

The bigger problem is who controls the label in the first place. Industry funds and conducts its own safety studies, then decides what to hand over to the EPA. If the EPA accepts the industry's version and finds no harm, that finding now bars any future lawsuits nationwide.

"There's a reason the industry wanted the EPA to be in charge of deciding what harms are caused," Siri said. "They know that is an actor they can control, unlike juries."
