Monsanto Co. v. Geertson Seed Farms, 561 U.S. 139 (2010), is a United States Supreme Court case decided 7-1 in favor of Monsanto.[1] The decision allowed Monsanto to sell genetically modified alfalfa seeds to farmers, and allowed farmers to plant them, grow crops, harvest them, and sell the crop into the food supply. The case came about because the use of the seeds was approved by regulatory authorities; the approval was challenged in district court by Geertson Seed Farms and other groups who were concerned that the genetically modified alfalfa would spread too easily, and the challengers won. Monsanto appealed the district court decision and lost, and appealed again to the Supreme Court, where Monsanto won, thus upholding the original approval and allowing the seeds to be sold.[2]
In 2005 the United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) deregulated Monsanto's Roundup-ready alfalfa (RRA) based on an Environmental Assessment (EA) of Monsanto's RRA.[3] In 2006, Geertson Seed Farm and others filed suit in a California district court against APHIS' deregulation of RRA.[4]
