In September 2015 the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced plans to list the pesticide glyphosate as a possible cancer threat under Proposition 65. OEHHA made the decision to list glyphosate following the International Agency for Research on Cancer March 2015 finding that glyphosate is “probably carcinogenic to humans.” Monsanto sued OEHAA in January 2016, in an effort to block the listing. Global sales of glyphosate were about $7.8 billion in 2014, as a carcinogen under Proposition 65. It is the main ingredient in Monsanto’s Roundup.
A tentative ruling by California Superior Court Judge Kristi Culver Kapetan states that the court intends to dismiss Monsanto’s lawsuit. In the lawsuit, Monsanto claimed that the listing was unconstitutional because OEHHA delegated law-making authority “to an unelected and non-transparent foreign body that is not under the oversight or control of any federal or state government entity,” and because the labor code process violated the due process clauses of the California and U.S. constitutions. In its motion to dismiss the lawsuit, California argued that IARC’s scientific determinations are “the gold standard in carcinogen identification.” The court found that Monsanto’s petition failed to state facts sufficient to constitute a cause of action.
Judge Kapetan will be issuing a formal decision soon.
