The California Supreme Court joined several federal courts in finding that state enforcement of federal organic standards is not preempted. See Quesada v. Herb Thyme Farms, Inc., 62 Cal. 4th 298 (2015). The plaintiff alleged that an herb grower violated California false advertising and fraud laws by selling conventionally grown herbs as organic. The court found that while federal law excludes states from defining “organic” or setting or approving certification procedures, federal law does not prevent state enforcement of the federal standards. The court observed that allowing “prosecution of [the type of fraud alleged in the case], whether by public prosecutors . . . or through civil suits by individuals or groups of consumers, can only serve to deter mislabeling and enhance consumer confidence.” The case did not involve the trickier situation where a plaintiff might seek to challenge whether a grower should have obtained organic certification. At least one court has found that such a state law challenge is preempted.
