The U.S. Supreme Court has overturned a lower court ruling in a landmark biotechnology case that has barred planting of genetically modified (GM) alfalfa since 2007. The ruling is a legal victory for Monsanto, which had appealed the lower court’s injunction preventing the company from selling the GM alfalfa. The case is important to Monsanto and other biotechnology firms because judicial reversal of USDA approvals could have dissuaded growers from using GM seeds if they are concerned approved traits could be rescinded years later, attorneys say. The high court’s decision also could affect a similar challenge related to GM sugar beets.
