Whether the APA requires an agency to use notice-and-comment procedures when it significantly revises a prior definitive interpretation of one of its regulations.
Holding
No. The APA categorically exempts interpretive rules from notice-and-comment requirements unless another statute requires those procedures, so an agency may amend or repeal an interpretive rule without notice and comment.
Reasoning
The APA defines rulemaking broadly to include formulating, amending, and repealing rules. But the provision that defines rulemaking, 5 U.S.C. § 551(5), does not itself specify the procedures an agency must follow. Those procedures appear in § 553, which expressly states that notice and comment do not apply to interpretive rules unless another statute provides otherwise.
The D.C. Circuit correctly recognized that agencies ordinarily must use the same procedures to amend or repeal a rule as they used to issue it. But that principle defeats, rather than supports, the Paralyzed Veterans doctrine: because an agency need not use notice and comment to issue an initial interpretive rule, it likewise need not use those procedures to revise or withdraw that interpretation.
A revised interpretation is not itself an amendment of the regulation being interpreted. To amend ordinarily means to alter the wording or legal text of a rule; to interpret means to explain the meaning of existing text. Interpretive rules do not have the force and effect of law, so a changed interpretation does not formally alter the underlying regulation.
The Court also rejected the argument that practical fairness concerns justified the D.C. Circuit’s rule. Under Vermont Yankee, the APA establishes the maximum procedural requirements courts may impose on agencies. Courts may not create an additional, judge-made right to notice and comment merely because they think it would be sound policy.
Regulated parties retain protections against arbitrary agency reversals. Under FCC v. Fox Television Stations, an agency must adequately justify a new policy when it contradicts prior factual findings or disregards serious reliance interests. Congress may also enact safe harbors, as it did in the FLSA, to protect employers who in good faith relied on a written agency interpretation later modified or rescinded.
