The Congressional Review Act is a 1996 statute that lets Congress void a federal agency rule by joint resolution. Before a rule can take effect, the agency must submit it to both chambers and to the Comptroller General, and a disapproval resolution must be introduced within 60 days of that submission. The President still has to sign it.
That is the whole machine. Almost every fight over it is a fight about the clocks: the Act sets several, they run on different calendars, and one of them restarts after a session ends. Miss the window and the expedited Senate procedure is simply unavailable.
What does the Congressional Review Act actually require?
The Act requires a filing and then permits a veto. Under Section 801 of Title 5, "before a rule can take effect, the Federal agency promulgating such rule shall submit to each House of the Congress and to the Comptroller General a report." Section 801(b)(1) then provides that a rule "shall not take effect (or continue), if the Congress enacts a joint resolution of disapproval."
The resolution is a form document. Section 802(a) prescribes the text: "That Congress disapproves the rule submitted by the ____ relating to ____, and such rule shall have no force or effect." There is no amendment, no middle version, no partial repeal. The rule survives intact or it is nullified.
A joint resolution is legislation, not a chamber statement, so it goes to the President like any bill. That fact explains most of the Act's history.
Which rules are covered, and what counts as "major"?
Coverage is broad and the exclusions are narrow. Section 804(3) borrows the definition of "rule" from Section 551 but carves out three categories: "any rule of particular applicability," "any rule relating to agency management or personnel," and "any rule of agency organization, procedure, or practice that does not substantially affect the rights or obligations of non-agency parties."
"Major rule" is a separate designation with its own consequence. Section 804(2) defines it as any rule the Administrator of the Office of Information and Regulatory Affairs finds has resulted in or is likely to result in "an annual effect on the economy of $100,000,000 or more," a major increase in costs or prices, or "significant adverse effects on competition, employment, investment, productivity, innovation," or on the ability of U.S. firms to compete abroad.
The designation buys Congress time. Section 801(a)(3) delays a major rule's effective date to the later of 60 days after Congress receives the report or 60 days after Federal Register publication. Non-major rules take effect on their own schedule while the window runs, so a resolution can nullify a rule already in operation.
What does the Government Accountability Office do here?
GAO is the third recipient of every rule and the referee on the ones that matter most. Agencies must submit a copy of each rule to both houses and to GAO before it can take effect, and GAO reports on major rules, including summaries of the procedural steps the agencies took, according to GAO's Congressional Review Act page.
GAO also issues legal opinions, on request, on whether a particular agency action is a "rule" within the Act's definition. That question is not academic. If a guidance document, bulletin, or memorandum qualifies as a rule and was never submitted, the submission that starts the 60-day clock has not happened — and a member can trigger the review process for an action the agency never treated as rulemaking at all.
How long does Congress have, and how does the Senate move?
Two different clocks run, and conflating them is the most common error. Section 802(a) requires a disapproval resolution to be introduced in the period beginning when Congress receives the agency's report "and ending 60 days thereafter." The Senate's expedited procedures are keyed to session days, which accumulate more slowly than calendar days and stretch the practical window past two months.
Inside the Senate, the fast track has three moving parts:
- A committee that has not reported the resolution after 20 calendar days "may be discharged from further consideration of such joint resolution upon a petition supported in writing by 30 Members of the Senate," under Section 802(c).
- A motion to proceed to the resolution is then in order and, under Section 802(d)(1), "is not subject to amendment, or to a motion to postpone."
- Section 802(d)(2) caps debate: "Debate on the joint resolution, and on all debatable motions and appeals in connection therewith, shall be limited to not more than 10 hours, which shall be divided equally between those favoring and those opposing."
Ten hours and no amendments means no filibuster, which means a simple majority. Ordinary legislation to overturn a rule would need 60 votes to end debate; a disapproval resolution needs 51.
What is the lookback period?
The lookback is a second review window for rules submitted at the end of a session. Section 801(d)(1) applies to any rule reported during the period beginning 60 session days (Senate) or 60 legislative days (House) before Congress adjourns a session, running "through the date on which the same or succeeding Congress first convenes its next session."
The mechanism is a legal fiction about dates. Under Section 801(d)(2)(A), such a rule is treated as though it were published in the Federal Register and reported to Congress on the 15th session day (Senate) or 15th legislative day (House) after the succeeding session convenes. The 60-day introduction window then runs fresh from that manufactured date.
This is why the provision dominates presidential transitions: rules finalized in an outgoing administration's last months arrive with their clocks reset for a new Congress. The reset is automatic and calendar-driven.
What happens to a rule after Congress disapproves it?
Disapproval is not a remand. Section 801(b)(2) provides that a nullified rule "may not be reissued in substantially the same form, and a new rule that is substantially the same as such a rule may not be issued, unless the reissued or new rule is specifically authorized by a law enacted after the date of the joint resolution disapproving the original rule."
Nothing in the Act defines "substantially the same form," and the statute assigns no one to decide it in the first instance. The practical effect is a durable constraint on the agency's authority in that area until Congress legislates again.
The Act also limits review of its own operation. Section 805 states: "No determination, finding, action, or omission under this chapter shall be subject to judicial review."
How often does a disapproval resolution actually become law?
Rarely, and in clusters. From 1996 through 2024, more than 461 disapproval resolutions were introduced in Congress and 20 became law, according to the George Washington University Regulatory Studies Center. The Center also notes that resolution filings rise after the presidential transitions of 2001, 2017, and 2021.
Those two facts describe the same constraint. Introduction is cheap; enactment requires majorities in both chambers plus a presidential signature — a combination that arrives mainly when unified control follows a transition, precisely when the lookback has just refilled the queue.
The clocks, side by side
| Clock | Statutory basis | What it counts | What it controls |
|---|---|---|---|
| Introduction window | Section 802(a) | 60 days after Congress receives the report | Whether a disapproval resolution may be introduced |
| Major-rule delay | Section 801(a)(3) | 60 days from receipt or publication, whichever is later | When a major rule may take effect |
| Committee discharge | Section 802(c) | 20 calendar days without a report | When 30 senators may discharge the committee |
| Floor debate | Section 802(d)(2) | 10 hours, divided equally | Whether a simple majority suffices |
| Lookback trigger | Section 801(d)(1) | 60 session or legislative days before adjournment | Which rules carry into the next session |
| Lookback reset | Section 801(d)(2)(A) | 15th session or legislative day of the new session | The date the fresh 60-day window starts from |
Frequently asked questions
Does a disapproval resolution need 60 votes in the Senate?
No. Section 802(d)(2) limits debate on the joint resolution and related debatable motions to 10 hours, divided equally between supporters and opponents. With debate capped and the motion to proceed not subject to amendment or postponement under Section 802(d)(1), passage turns on a simple majority rather than a cloture threshold.
Can Congress amend a rule instead of killing it?
Not through this route. Section 802(a) fixes the resolution's text as a flat statement that Congress disapproves the rule and that it "shall have no force or effect." The instrument offers one outcome. Modifying a rule requires ordinary legislation or a new rulemaking by the agency.
What happens if an agency never submits a rule to Congress?
The submission is what starts the review period, so an unsubmitted rule has no running clock. GAO issues legal opinions, on request, on whether a given agency action qualifies as a rule under the Act, per its Congressional Review Act page. Section 801(a)(1)(A) conditions a rule taking effect on that report being submitted.
Does the lookback period depend on an election?
No. Section 801(d)(1) is triggered by the calendar of session and legislative days before a session adjourns, not by any electoral event. Rules reported inside that window are treated under Section 801(d)(2)(A) as reported on the 15th session or legislative day of the succeeding session, whoever is in office.
Can a nullified rule come back?
Only with new legislation. Section 801(b)(2) bars reissuing the rule "in substantially the same form" and bars a new rule that is substantially the same, unless specifically authorized by a law enacted after the date of the disapproving joint resolution. The statute does not define how similar is too similar.
