The U.S. Supreme Court today overturned (.pdf) some aspects of a lower court's nationwide injunction against genetically modified (GM) alfalfa.
However, it appears that GM alfalfa planting will not restart right away. A USDA decision would be required for temporary approval. More importantly, the court left in place the lower court's ruling that a formal Environmental Impact Statement (EIS) is required before the technology receives permanent approval.
I feel the result is not exactly a victory for those who oppose all GM technology, nor exactly a victory for the technology's sponsor, Monsanto. It seems to be a victory for the idea that GM technology deserves a strong federal environmental review, including careful attention to the right of conventional farmers to preserve non-GM production if they choose. Monsanto's opponents in this case were farmers who objected to having GM seeds blow into their conventional fields, limiting their ability to market a non-GM crop.
A Monsanto press release claimed the Supreme Court decision as a win. So did a press release from the anti-GM Center for Food Safety. The story was covered by Reuters and AP. On related issues, I follow Grist Magazine's food channel. Matt Jenkins at High Country News in 2007 had a nice long feature on this controversy.
