Judge Leval maintained that the majority mischaracterized Vermont’s interest as bare consumer curiosity. In his view, the record and the district court’s findings showed that Vermont acted in response to consumer concerns about possible long-term human-health effects, harms to cows, economic pressure on small dairy farms, and ethical objections to biotechnology.
The FDA’s present conclusion that rBST milk was safe did not, in Judge Leval’s view, eliminate the legitimacy of public concern about a relatively new biotechnology. He emphasized the limits of preapproval testing and the possibility that risks may emerge only after a product has been widely used over time.
Those health, animal-welfare, economic, and ethical concerns were substantial governmental interests, whether considered separately or together. Vermont did not need to establish that rBST was actually harmful before requiring disclosure of its use; the state could reasonably permit consumers to make choices in light of uncertainty and concerns surrounding the production method.
Judge Leval also stressed that a truthful disclosure requirement burdens commercial speech far less than a ban on speech. The First Amendment’s commercial-speech doctrine generally protects the consumer’s interest in receiving accurate information, so he viewed the manufacturers’ effort to withhold their use of rBST as contrary to the informational values underlying that doctrine.
The retailer sign expressly attributed its policy explanation to Vermont and also stated the FDA’s conclusion that no significant difference existed between milk from treated and untreated cows. Thus, Judge Leval believed consumers would not attribute the sign’s message to the manufacturers, and the disclosure did not force them to engage in an ideological debate.
He would have affirmed the denial of preliminary relief. He also noted that the majority’s likelihood-of-success ruling did not finally resolve the merits and that Vermont could further establish its substantial interests at trial.
