Between 1991 and 1997, Melaleuca was investigated by Michigan regulators, the Idaho attorney general's office, and the U.S. Food and Drug Administration for various marketing violations. In 1991 Melaleuca received a cease-and-desist order for violating Michigan’s anti–pyramid scheme laws.[68] In 1992, Melaleuca signed a consent decree with the states of Michigan and Idaho agreeing to "not engage in the marketing and promotion of an illegal pyramid." By September of that year, "officials in both states cleared the company's marketing plan and blamed 'renegade' distributors for any problems."[72] In its voluntary agreement, the Idaho Attorney General found the company's policies and product catalog did not violate Idaho law, but that "certain independent marketing executives of Melaleuca... failed to comply with certain policies of Melaleuca, and that the actions of these independent marketing executives are in violation of Idaho law."[71] In 1997, the U.S. Food and Drug Administration sent Melaleuca a warning letter for "false and misleading" claims about two of its supplements.
