On August 6, 2025, Association of Home Appliance Manufacturers—a trade association with members that manufacture gas and electric cooking products and other appliances—filed a lawsuit in the federal district court for the District of Colorado challenging a Colorado law requiring dissemination of what the plaintiff alleged was “a non-consensus, scientifically controversial, and factually misleading government-mandated message about the purported ‘health impacts’ of gas stoves that is contrary to the view of the World Health Organization, the U.S. Government Accountability Office, and federal agencies responsible for ensuring the health and safety of American consumers.” The plaintiff alleged that the law’s disclosure requirements violate the First Amendment because they are content- and viewpoint-based. The plaintiff also alleged that the law violated its members’ First Amendment rights because the legislative record showed that the legislation was not driven by purported health impacts “but instead by the unrelated policy debate on climate change and decarbonization.”
