An appeal by organic farmers [of] a court ruling last year turned into a wide-ranging protest this morning with speakers skewering Monsanto Co. for its policies and demanding labeling of genetically modified food. About 200 people, many from organic seed companies, rallied in a park directly across from the White House. The protest suggested an uptick in efforts to demand labeling, which was defeated in a California ballot initiative in November. Monsanto spent at least $8 million in an industry-wide effort to sink the California proposition. Organic farmers, who are pressing a lawsuit against Monsanto, often complain that their products are threatened by wind-blown pollen from genetically altered crops. We want and demand the right of clean seed not contaminated by a massive biotech company that's in it for the profit," Carol Koury, who operates Sow True Seeds in Asheville, N.C., said at the rally. The gathering was held in conjunction with an appeal heard today before a three-judge U.S. Court of Appeals panel in Washington. The suit questions the legality of Monsanto's seed patents and seeks protection from patent-infringement suits against farmers in the event their fields are found to contain genetically modified seed. Last February, U.S. District Judge Naomi Buchwald in the Southern District of New York dismissed the suit.
