How Federal Agencies Repeal Regulations: The APA Workflow

Repealing a federal regulation is often described in the press as if an agency can simply announce a rule no longer applies. In reality, undoing a regulation generally requires almost the same formal process that created it in the first place, governed by the Administrative Procedure Act of 1946. Skipping steps in this process is one of the most common reasons repeal efforts get struck down in court.

Why Repeal Isn’t Simpler Than Creation

The Administrative Procedure Act treats the repeal of an existing rule as itself a form of rulemaking, meaning an agency generally cannot simply announce that a regulation is no longer in effect. The Supreme Court reinforced this principle in a 1983 case involving an automobile safety standard, holding that an agency changing its regulatory position must supply a reasoned explanation for the change, not merely assert a new policy preference, and must genuinely grapple with the factual findings that supported the original rule.

Step 1: Internal Agency Review

Before any public action, the agency typically conducts an internal review of the existing rule, gathering updated data, legal analysis, and often an updated cost-benefit assessment, especially for economically significant regulations that originally required formal review by the Office of Management and Budget’s Office of Information and Regulatory Affairs.

Step 2: Notice of Proposed Rulemaking

The agency publishes a Notice of Proposed Rulemaking in the Federal Register, explaining the proposed repeal or revision and the reasoning behind it. This notice must include enough detail for the public to meaningfully understand and respond to what is being proposed; a notice that is too vague or that fails to disclose the agency’s actual reasoning is itself a common ground for later legal challenge.

Step 3: Public Comment Period

Following publication, the agency must provide a period, commonly 30 to 60 days though it varies, during which members of the public, businesses, advocacy groups, and other stakeholders can submit comments. This is not a symbolic formality. Courts have repeatedly required agencies to genuinely consider significant comments raised during this period and to explain, in the final rule, why they accepted or rejected the substantive points raised, particularly comments presenting new data or research that cuts against the agency’s proposed action.

Step 4: Responding to Comments and Drafting the Final Rule

After the comment period closes, agency staff compile and respond to the comments received, which can take anywhere from several months to multiple years depending on the volume and complexity of public input and the rule’s significance. The final repeal document must explain how the agency weighed the evidence, including evidence that originally justified the rule being repealed, and why it now reaches a different conclusion.

Step 5: Publication and Effective Date

The final rule is published in the Federal Register with an effective date, typically no sooner than 30 days after publication for most rules, giving regulated parties time to adjust. Major rules, generally those with an annual economic effect above a set threshold, are also subject to congressional review procedures that can, in narrow circumstances, allow Congress to overturn the action through a joint resolution.

Step 6: Judicial Review

Parties who believe the repeal was improperly conducted, whether because the agency failed to adequately justify the change, ignored significant record evidence, or skipped required procedural steps, can challenge the repeal in federal court. Courts applying the “arbitrary and capricious” standard under the APA do not re-decide the underlying policy question themselves, but they do closely examine whether the agency’s own stated reasoning holds together and whether it engaged seriously with the existing factual record, including the findings that justified the original rule.

The Workflow at a Glance

Shortcuts That Tend to Backfire

Agencies sometimes attempt to bypass part of this process by invoking the APA’s “good cause” exception, which allows skipping notice and comment when it is impracticable, unnecessary, or contrary to the public interest, typically reserved for genuine emergencies. Courts have been notably skeptical of agencies invoking this exception simply to move faster on a politically desired repeal, and rules repealed this way face a materially higher risk of being vacated and sent back through the full process. This is the core reason why even a repeal effort with clear political and executive support can take a year or more to survive legal scrutiny if the underlying rule was substantial and well-documented when it was first adopted.

What Happens When a Court Vacates a Repeal

If a court finds a repeal procedurally deficient, the typical remedy is to vacate the repeal, meaning the original regulation legally snaps back into effect as though the repeal had never happened, rather than leaving a regulatory gap. This can create considerable practical confusion for regulated businesses that had already adjusted their operations to the repeal’s assumption, since compliance obligations can suddenly reappear with little advance notice. Agencies sometimes respond to a vacated repeal by attempting the process again, this time more carefully addressing the specific procedural defect the court identified, which can mean the entire multi-step process described above effectively restarts from the notice-and-comment stage.

Why Some Rules Are Easier to Repeal Than Others

Not all regulations carry equal legal weight once an agency decides to revisit them. A rule adopted hastily with a thin factual record and limited public comment is generally easier to repeal cleanly, since there is less underlying analysis the agency must directly contradict or explain away. A rule built on extensive scientific or economic research, defended through multiple rounds of litigation, and reaffirmed across several years presents a much higher bar, because the repealing agency must engage substantively with all of that accumulated record rather than simply asserting a change in policy preference. This asymmetry is one reason some regulatory repeal efforts move quickly while others become multi-year legal battles even when the responsible agency and the president are in full agreement about the desired outcome.
