In August 2011, five tobacco companies filed a lawsuit against the FDA in an effort to reverse the new warning mandate. Tobacco companies claimed that being required to promote government anti-smoking campaigns by placing the new warnings on packaging violates the companies' free speech rights. Additionally, R.J. Reynolds, Lorillard, Commonwealth Brands Inc., Liggett Group LLC and Santa Fe Natural Tobacco Company Inc. claimed that the graphic labels are an unconstitutional way of forcing tobacco companies to engage in anti-smoking advocacy on the government's behalf. A First Amendment lawyer, Floyd Abrams, represented the tobacco companies in the case, contending that requiring graphic warning labels on a lawful product cannot withstand constitutional scrutiny. The Association of National Advertisers and the American Advertising Federation also filed a brief in the suit, arguing that the labels infringe on commercial free speech and could lead to further government intrusion if left unchallenged.
