The Congressional Review Act is a 1996 statute that lets Congress void a finished federal regulation by simple majority and then blocks the agency from writing a similar one ever again. The second half is the real instrument: a disapproved rule "may not be reissued in substantially the same form" absent a new law, under 5 U.S.C. 801(b)(2).
Most descriptions of the law stop at the fast clock — sixty days, expedited Senate floor procedure, no filibuster. The clock explains why the CRA is used in bursts. The permanence clause explains why a single vote can settle a regulatory question for a decade, and why the fight over the statute has shifted from whether Congress will use it to what Congress is allowed to point it at.
What does the statute actually require?
Before a rule takes effect, the issuing agency must send Congress and the Comptroller General a copy of the rule, a statement of whether it is "major," and the proposed effective date, along with supporting cost-benefit and compliance material. That submission requirement sits in 5 U.S.C. 801.
Submission is the trigger. Until an agency files, the review clock never starts — a detail that has become the statute's most contested feature.
"Major" is not a rhetorical label. Section 804 defines it as a rule the Office of Management and Budget's Administrator finds will have an annual effect on the economy of "$100,000,000 or more," or will cause substantial cost increases, or will significantly harm competition, employment, investment, or productivity. Major rules cannot take effect for 60 days after submission or Federal Register publication, whichever comes later.
The definition of "rule" borrows from the Administrative Procedure Act but carves out rules of particular applicability, internal agency management and personnel matters, and procedural rules that do not substantially affect outside parties.
How does a disapproval resolution actually move?
It moves on a track built to defeat delay. Section 802 supplies the vehicle and strips out most of the ways the Senate normally kills things.
- A member introduces a joint resolution within 60 days of the agency report reaching Congress, excluding recesses longer than three days. The operative text is fixed by statute: "That Congress disapproves the rule submitted by the ____ relating to ____, and such rule shall have no force or effect."
- If the Senate committee of referral has not reported within 20 calendar days of submission or publication, 30 senators may sign a discharge petition that places the resolution directly on the calendar.
- The motion to proceed is not debatable, not amendable, and not subject to a motion to postpone.
- Floor debate is capped at "not more than 10 hours, which shall be divided equally between those favoring and those opposing the joint resolution."
- The expedited procedure expires after 60 session days from the applicable date — or, for rules submitted late in a Congress, after 60 session days beginning on the 15th session day of the next Congress.
That last item is the lookback mechanism, and it is why disapprovals cluster after a change of administration. Rules finalized in an outgoing president's last weeks get a fresh review window in the new Congress, when a new president is available to sign the resolution. A joint resolution is legislation; without a signature it needs two-thirds in both chambers.
Why did the CRA sit unused for twenty years?
Because the arithmetic almost never worked. A disapproval requires majorities in both chambers plus a presidential signature, which in practice means unified party control immediately following a party change in the White House. Outside that window, the president who owns the rule holds the veto.
The usage record tracks that logic closely. Research published by Harvard Law School's Environmental and Energy Law Program counts one rule disapproved before 2017, 16 in 2017, three in 2021, and 22 in 2025 — the largest single-Congress total to date.
| Period | Rules disapproved |
|---|---|
| 1996–2016 | 1 |
| 2017 | 16 |
| 2021 | 3 |
| 2025 | 22 |

What happens to an agency after a rule is disapproved?
The rule does not take effect, or ceases to have effect, and the agency loses the ability to re-regulate in that space. Section 801(b)(2) forbids reissuing the rule in substantially the same form and forbids a new rule that is substantially the same, unless a law enacted after the disapproval specifically authorizes it.
The statute never defines "substantially the same." Courts began filling that gap only recently. In Ohio Telecom Association v. FCC, decided in August 2025, the Sixth Circuit majority held that the comparison runs between the entire disapproved rule and the entire subsequent rule, and concluded that a narrower 2024 FCC data-breach order was not substantially the same as the broader 2016 order Congress had struck. The dissent read the bar more strictly, arguing that components of a disapproved rule cannot resurface at all.
Section 805 compounds the stakes by providing that no determination, finding, action, or omission under the chapter is subject to judicial review. Two circuits have agreed that constitutional challenges fall outside that bar, though both rejected the specific claims before them.
Who decides what counts as a rule?
The Government Accountability Office does the technical work, and Congress is not bound by its answer. Under the CRA, agencies file every covered rule with GAO, which maintains a searchable database of submissions, issues reports on major rules, and — when a member of Congress asks — writes legal opinions on whether a particular agency action is a "rule" that should have been submitted at all. GAO describes those functions on its own Congressional Review Act page.
Those opinions have become an offensive tool. If GAO concludes that a guidance document or a plan was a rule that was never submitted, the review clock arguably starts on the date of that opinion — years after the action itself. In 2025 Congress used that route on four Interior Department resource management plans covering Montana, North Dakota, Alaska, and Wyoming, which GAO found met the APA's definition of a rule; all four were disapproved.
What is the strongest case against reading the statute this broadly?
That the CRA's expedited procedure was written for rules, and stretching it past GAO's own judgment converts a narrow legislative check into a general-purpose veto over agency action. The 2025 California episode is the sharpest example, and it cuts against the expansive reading rather than for it.
Congress disapproved three EPA notices approving California Clean Air Act preemption waivers. Both GAO and the Senate parliamentarian concluded the waivers were not rules subject to the CRA. The Senate proceeded anyway, voting 51-44 on May 22, 2025, in a step Democrats called the nuclear option, as CBS News reported.
The answer to that objection is narrower than its supporters usually claim. Nothing in the text makes GAO's opinion or the parliamentarian's advice binding, and section 805 makes the resulting determination hard to challenge in court. But a majority willing to override both is not applying the CRA's procedure so much as demonstrating that a simple-majority chamber can define the procedure's reach for itself. That is a durable precedent available to whichever party next holds the floor — and the pending California litigation raises federalism and separation-of-powers arguments precisely because the judicial-review bar leaves so little else.
What does this change?
It changes what a finalized regulation is worth. An agency rule completed in the last months of an administration now carries a known expiration risk tied to the lookback window, which pushes consequential rulemaking earlier in a presidential term and pushes contested policy toward instruments the CRA does not obviously reach.
It also raises the cost of losing. Ordinary repeal leaves an agency free to try again; a CRA disapproval does not, and the Sixth Circuit's whole-rule comparison is currently the only judicial guidance on how much room remains.
And it moves the decisive question upstream. The live disputes in 2025 were not about whether Congress could disapprove a rule. They were about whether an agency action was a rule, when it was submitted, and who gets the last word on both — questions GAO answers, the parliamentarian advises on, and a floor majority can currently resolve on its own.
