Case Brief Summary & Legal Analysis
tl;dr: An agency issued policy letters defining a term in its regulations without public notice and comment. The D.C. Circuit held these were permissible “interpretive rules,” not “legislative rules,” because they only clarified an existing legal duty rather than creating a new one.
Legal Significance: This case established a key D.C. Circuit test for distinguishing legislative from interpretive rules under the Administrative Procedure Act, focusing on whether a rule has independent legal effect or effectively amends a prior legislative rule.

Case Facts & Court Holding
Key Facts & Case Background
The Mine Safety and Health Administration (MSHA) promulgated regulations via notice-and-comment rulemaking requiring mine operators to report any “diagnosed” occupational illness, including pneumoconiosis. The term “diagnosed” was not defined in the regulation. In response to industry inquiries, MSHA issued a series of Program Policy Letters (PPLs) without notice and comment. The PPLs stated that for reporting purposes, a chest x-ray rating of 1/0 or higher on the International Labor Office (ILO) scale constituted a “diagnosis” of pneumoconiosis. The American Mining Congress, a trade association, challenged the PPLs, arguing they were legislative rules that effectively amended the existing regulation and were therefore invalid because MSHA failed to follow the Administrative Procedure Act’s (APA) notice-and-comment procedures. MSHA defended its actions by asserting that the PPLs were merely interpretive rules, which are exempt from notice-and-comment requirements under APA § 553(b)(3)(A).
Court Holding & Legal Precedent
Issue: Are an agency’s Program Policy Letters, which define a term contained in a pre-existing, validly promulgated legislative rule, exempt from the APA’s notice-and-comment requirements as interpretive rules?
The Program Policy Letters are interpretive rules and are therefore exempt from Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
