State law

Monsanto has alleged that the OEHHA's decision to list glyphosate on the Proposition 65 list of chemicals that are known to the state to cause cancer is unconstitutional as applied to glyphosate, and has attempted to challenge the Labor Code listing mechanism as unconstitutional on its face. After failing in court, Monsanto fails again at the appellate court on 4.19.2018. The ruling became final on 8.15.2018 when the state’s high court denied review.
