Yesterday, the Supreme Court issued a ruling in Monsanto v. Geerston Farms, the first ever GMO crops case to be presented before the Court. A lower court ruled in 2007 that Monsanto Round-Up resistant alfalfa seeds could not be planted by farmers. The Supreme Court overturned much of the ruling, saying "the lower court had gone too far and that the USDA had the power to approve planting in small and controlled settings" (Serious Eats).
Monsanto is happy for the possibility to get their seeds on the market, but the ruling came with enough restrictions that many basically view the ban as still active.
The Center for Food Safety posted yesterday:
"Although the High Court decision reverses parts of the lower courts’ rulings, the judgment holds that a vacatur bars the planting of Monsanto’s Roundup Ready Alfalfa until and unless future deregulation occurs."
