755 F.2d 1098 (4th Cir. 1985)
Chocolate Manufacturers v. Block is a staple of Administrative Law courses because it crystallizes the "logical outgrowth" doctrine under the Administrative Procedure Act's notice-and-comment requirements.
Whether the USDA's final WIC regulation prohibiting WIC nutrition education materials from promoting or mentioning certain sweetened foods (including chocolate milk) was a logical outgrowth of the proposed rule, as required by the APA's notice-and-comment procedures.
Under APA § 553, an agency must publish notice of either the terms or substance of the proposed rule or a description of the subjects and issues involved, and must allow interested persons an opportunity to comment. A final rule is valid only if it is a logical outgrowth of the proposed rule—meaning the notice must alert interested parties to the possibility of the agency adopting the final approach so that they have a fair opportunity to comment. Agencies may refine proposals in response to comments, but they may not materially alter the content or scope of the rule in a way that interested parties could not reasonably have anticipated based on the notice. When notice is inadequate, the failure of a party to comment does not bar judicial review, and the remedy is typically to vacate the offending portions and remand to the agency.
No. The final prohibition on promoting or mentioning certain sweetened foods in WIC nutrition education materials, including the specific reference to flavored (chocolate) milk, was not a logical outgrowth of the USDA's proposed rule. The court vacated the challenged portion of the regulation and remanded to the agency.
Chocolate Manufacturers v. Block is a cornerstone for the logical outgrowth doctrine. It teaches that agencies cannot use notice-and-comment as a placeholder and then adopt a final rule that is qualitatively different from what was proposed. The case is routinely cited to assess whether a final rule is fairly encompassed within the subjects and issues identified in the notice. For law students, it highlights how procedural safeguards shape substantive outcomes: inadequate notice can invalidate regulatory choices regardless of their merits. The case also underscores that a party's failure to comment does not foreclose judicial relief when the rulemaking notice itself was deficient.
