A U.S. appeals court…struck down a law that requires tobacco companies to use graphic health warnings, such as of a man exhaling smoke through a hole in his throat. The 2-1 decision by the court…contradicts another appeals court's ruling in a similar case earlier this year, setting up the possibility the U.S. Supreme Court will weigh in on the dispute. The court's majority in the latest ruling found the label requirement from the U.S. Food and Drug Administration violated corporate speech rights…Five tobacco companies representing most of the major cigarette makers in the United States challenged the FDA rules: Reynolds American Inc, Lorillard Inc; Commonwealth Brands Inc, which is owned by Britain's Imperial Tobacco Group Plc; Liggett Group LLC and Santa Fe Natural Tobacco Co Inc. The FDA has argued the images of rotting teeth and diseased lungs are accurate and necessary to warn consumers…about the risks of smoking.
