Whether FDA’s 20-parts-per-billion aflatoxin action level was a legislative rule that required notice-and-comment rulemaking under the Administrative Procedure Act.
Holding
Yes. FDA gave the action level present, binding effect, making it a legislative rule that could not validly be issued without notice and comment.
Reasoning
The APA exempts interpretive rules and general statements of policy from notice-and-comment procedures, but not legislative rules. Under D.C. Circuit precedent, the central inquiries are whether the agency pronouncement creates present rights or obligations and whether it genuinely leaves agency decisionmakers free to exercise discretion. FDA’s label for its own action levels as enforcement-policy statements received some deference, but the court gave greater weight to the language FDA used and the practical effect FDA assigned to the levels.
FDA’s regulations described an action level as defining the contamination level at which food “will be deemed” adulterated and as potentially prohibiting any detectable quantity of a substance. That mandatory language did not merely forecast future enforcement priorities. It indicated that, once set, an action level established a presently applicable and binding norm.
FDA’s exemption procedure reinforced that conclusion. The agency allowed it to exempt from regulatory action food that was otherwise unlawfully contaminated. Requiring a producer to obtain an exception implies that food over the action level is unlawful unless exempted; that consequence could arise only because FDA treated the action level itself as binding.
FDA’s own enforcement communications likewise treated 20 parts per billion as a fixed legal threshold. In a Federal Register notice, FDA stated that food containing more than 20 parts per billion of aflatoxin was adulterated and could not be shipped in interstate commerce. Such language conveyed more than an agency intention that might later be reconsidered case by case.
The court acknowledged that an action level did not bind producers in every respect: in an enforcement action, FDA would still have to prove that the food was adulterated under the statute rather than simply prove noncompliance with the level. But FDA had effectively bound itself, because it would be extraordinarily difficult for the agency to justify prosecuting a producer whose corn contained less than 20 parts per billion. That substantial restriction on enforcement discretion made the action level legislative in character.
The ruling was narrow. FDA remained free under the FDC Act to use genuinely nonbinding action levels as policy statements. But if FDA chose to accord an action level substantive and binding significance, it had to promulgate that level through APA notice-and-comment procedures.
