Deregulation Without Repeal: Why the Rules Are Still on the Books
Most of the current US deregulation has not removed a single line from the Code of Federal Regulations. It suspended enforcement instead, leaving obligations legally live, judicially contestable and reversible by the next administration.

The consensus reads the past eighteen months as a sweeping deregulatory push, and compliance budgets have started to move accordingly. The quieter fact is that comparatively little has been repealed. The dominant instruments have been non-enforcement announcements, delays and fast-track repeals that either sit unfinished or rest on a legal theory agencies themselves have declined to use. In May 2026 the Government Accountability Office ruled that one such announcement was itself a rule, reviewable by Congress. What a firm is legally obliged to do and what it is currently asked to do have come apart, and the gap closes between 2027 and 2029.
Signal Identification
This is a regulatory pivot masquerading as a regulatory retreat. Obligations that appear withdrawn remain codified and enforceable by successors, courts, state authorities and private litigants. The signal is the accumulating stock of live-but-unenforced rules, not the volume of announcements.
What's Changing
The legal status of non-enforcement has been tested and found wanting. Reviewing Commerce's announcement that it would not enforce the AI Diffusion Rule, the GAO concluded that "the Press Release meets the APA definition of a rule and that no CRA exception applies" (GAO, 12/05/2026). Commerce itself confirmed the rule "remains in the Code of Federal Regulations" pending a rulemaking it has not completed. An instruction to enforcement staff is therefore a reviewable act, and the obligation it suspends stays live.
The fast-track repeal route has meanwhile stalled. A Bloomberg Law review found that of "about 2,800 rules" published since the mandated review period closed, "only two other agencies have used the good cause exception based on one of the cases that the White House highlighted" (Bloomberg Law, 26/05/2026). Where good cause is used it works narrowly: the FCC's seventh direct final rule accounts for roughly "1,274 rule provisions, 149,566 words, and more than 338 pages" of deletions, and takes effect automatically only absent adverse comment (Federal Register, 22/06/2026).
The paperwork tells the same story. The 2026 Unified Agenda runs to 3,954 entries, "the highest count since 2012", against only 1,519 final rules published, because undoing a rule usually requires writing one (Competitive Enterprise Institute, 06/07/2026). Brookings tracks the resulting mixture of "new, delayed, and repealed rules, notable guidance and policy revocations, executive actions, and important court battles" (Brookings Institution, 02/07/2026), including a status category for rules only partially in effect.

Disruption Pathway
Stage one, through 2027, is legal testing. Anticipatory repeals, in which agencies argue a rule was unlawful from the outset, reach the courts; the Harvard Law Review reading is that the strategy seeks to repeal rules "not on the grounds that conditions have shifted or priorities changed but that the rule is illegal and was promulgated ultra vires", and that this provides "no procedural escape hatch" from the duty to weigh reliance interests (Harvard Law Review, 13/03/2026). Stage two, 2027 to 2029, is the reckoning: rules never formally repealed become available again to a successor administration, to state enforcers and to private plaintiffs, with no new rulemaking required. Firms that cut controls against the posture rather than the legal text carry that exposure forward.
Stresses concentrate in three places: sectors where a single suspended rule underpinned a capital decision, notably energy and export-controlled semiconductors; compliance functions that cut headcount against announced relief; and multinational groups whose non-US regulators never adopted the US posture at all. Two adaptations follow. Operationally, obligation registers track the codified text, with enforcement posture logged as a separate volatile field. In legal and audit functions, reliance interests get documented contemporaneously, since that record is the asset that matters when the pendulum swings.
Why This Matters Now
Boards, general counsel and chief compliance officers are being asked this budget cycle to bank savings from relief with no completed legal instrument behind it. What needs revising is the assumption that an agency announcement equals a repeal. Counsel are blunt on the point: "Limitations periods outlast any administration, so significant compliance rollbacks remain risky" (Sher Tremonte LLP, 21/07/2026), and the whistleblower and qui tam channels operate whatever the agency's appetite. Audit committees should ask which register entries are suspended rather than removed, and what revival would cost. Investors in regulated infrastructure should price the reversal scenario rather than assume today's posture holds to the asset's horizon.
Decision-action posture for this signal: Prepare: the exposure is already accruing, but the trigger for capital commitment is the first completed repeal or adverse court ruling in a firm's own rule set.
Counter-Argument
The strongest objection is that unenforced rules do not bind in practice. As one administrative law scholar puts it: "Just because a rule is still on the books, it doesn't mean much if nobody is willing to enforce the rule or nobody is in office to enforce the rule" (Bloomberg Law, 26/05/2026). Staffing cuts may prove more durable than any repeal, and a firm paying for controls nobody checks is subsidising a hypothetical.
The counter-counter is that the objection holds only for agency enforcement, which is the one channel a successor can switch back on overnight. It does not hold for state attorneys general, qui tam relators, lender covenants written against the codified text, or limitation periods running past the current term. The asymmetry decides it: the saving is annual, the exposure is cumulative.
Implications
Taken together, the sources suggest durable change in method rather than a transient political episode: the operative instrument of US regulatory policy has shifted from the rule to the posture, and posture is cheap to set and cheap to reverse. That cuts both ways over 2026 to 2029. Firms treating the codified text as the binding constraint and the posture as weather can move fast when relief is genuine and absorb nothing when it evaporates. Those that restructured against announcements are exposed. The deeper cost is to planning: when the baseline can change without a legal instrument, capital allocation loses its anchor.
Early Indicators to Monitor
- Commerce publishes the promised rulemaking rescinding and replacing the AI Diffusion Rule, or submits the non-enforcement policy to Congress as GAO requires.
- A court sets aside an anticipatory repeal for failing to weigh reliance interests, as the Regents line of authority contemplates.
- A state attorney general brings an action enforcing a federal standard the responsible agency has declined to enforce.
- An agency withdraws a direct final rule after receiving significant adverse comment, showing the fast-track route is contestable in practice.
- Auditors or lenders require disclosure of obligations suspended by policy but not repealed by rule.
Disconfirming Signals
- Agencies complete formal notice-and-comment repeals for the major suspended rules, removing them from the Code of Federal Regulations outright.
- Courts uphold the good-cause repeal theory broadly, and agency use of the exception rises sharply from the current handful.
- Congress codifies the deregulatory changes in statute, putting them beyond reversal by a successor administration.
- Two consecutive administrations maintain the same non-enforcement posture, establishing it as a stable baseline for planning.
- State enforcers and private plaintiffs conspicuously fail to fill the federal enforcement gap over a sustained period.
Strategic Questions
- Should the compliance budget be set against the codified obligation or the current enforcement posture?
- Which suspended rules, if revived in 2029, would require capital the current plan does not carry?
- At what evidence threshold does announced relief justify decommissioning a control rather than mothballing it?
