Opponents of Vermont’s new GMO labeling law are citing a recent federal court ruling in Hawaii to try to block the Center for Food Safety from helping to defend Vermont, Politico reported Wednesday.

On Aug. 22, Judge Barry Kurren denied the Center for Food Safety’s request to intervene on behalf of Hawaii County to defend the county’s new partial ban on genetically engineered crops. The Hawaii Floriculture and Nursery Association and several other farming groups sued the county in June saying that the law was unfair and burdensome.

Politico reported that just five days after the ruling, the Grocery Manufacturers Association filed a notice of supplemental authority in its case challenging Vermont’s new GMO labeling law.

“CFS had failed to rebut the presumption of adequate representation by the government, and that amicus status would provide CFS sufficient means to express its views,” GMA argued.

Hawaii has become a hotbed for legislation and litigation regarding genetically modified farming as more residents have grown fearful of living near fields owned by Monsanto Company and other biotech giants.

Kurren recently struck down a Kauai County ordinance that required more disclosure from biotech companies, saying that counties don’t have the authority to regulate pesticide use.
