APA review: challenging a federal agency's action in court
A federal claim in United States district courts · Last verified August 26, 2026
The Administrative Procedure Act is the master key to suing the federal government over what it decided rather than what it did to you physically. A rule you cannot live with, a permit denied, a benefit terminated, a designation that costs you your business — this is the route.
Two decisions in 2024 changed it more than anything in forty years. One ended judicial deference to an agency's reading of an ambiguous statute. The other reopened the window to challenge regulations that have been on the books for decades.
What the claim is
A federal agency did something — issued a rule, denied an application, revoked a licence, made a determination — and you want a court to set it aside.
You are not asking for money. The relief is vacatur and remand, an injunction, or a declaratory judgment. If what you want is damages, this is the wrong statute.
Where the right comes from
An express review vehicle that also waives sovereign immunity, but only partway:
A person suffering legal wrong because of agency action, or adversely affected or aggrieved by agency action within the meaning of a relevant statute, is entitled to judicial review thereof.
Four gates control whether you get through the door, and failing any one defeats review:
- The sovereign immunity waiver reaches only relief "other than money damages." It stops at the money.
- Final agency action. Under Bennett v. Spear, the action must "mark the 'consummation' of the agency's decisionmaking process" and be one "by which 'rights or obligations have been determined,' or from which 'legal consequences will flow.'" A staff letter, a guidance document, an interim step — usually none of these qualify.
- Not committed to agency discretion by law. Review is unavailable where there is "no law to apply" — the standard from Heckler v. Chaney, which is why an agency's decision not to enforce is generally unreviewable.
- No other adequate remedy in a court. If a specific review statute covers the action, use that one.
Treat these as the gate. Most APA cases that fail, fail here rather than on the merits.
What a plaintiff has to prove — the standard of review is the elements
The core provision directs a court to set aside agency action found to be "arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law."
That review is confined to the administrative record the agency compiled. You do not take discovery, you do not build a new record, and the court does not substitute its policy judgment. What it asks is whether the agency considered the relevant factors, explained itself, and drew a rational connection between the facts and the choice it made.
And here is the change. In Loper Bright Enterprises v. Raimondo (2024) the Supreme Court overruled Chevron. Courts now "exercise independent judgment in determining the meaning of statutory provisions," even ambiguous ones. An agency's interpretation may be persuasive; it is no longer binding. Any source telling you a court must accept a reasonable agency reading is describing law that no longer exists.
A separate substantial-evidence standard governs formal, on-the-record proceedings.
How long you have to file
Six years, under the default period for civil actions against the United States, unless a specific review statute supplies something shorter. Many do — some are as short as 60 days — so check the governing statute before relying on six years.
When the clock starts changed in 2024. In Corner Post, Inc. v. Board of Governors the Court held an APA claim "does not accrue for purposes of §2401(a)'s 6-year statute of limitations until the plaintiff is injured by final agency action" — not when the rule was promulgated.
The consequence is large. A business formed in 2023 can challenge a rule issued in 1990, because its own six years began when the rule first injured it. That reopened challenges everyone had assumed were long closed.
This is a limitations period, not a statute of repose.
What has to happen before you file
Usually nothing. This surprises people who assume administrative exhaustion is always required.
Under Darby v. Cisneros, APA exhaustion is required only where a statute or an agency rule mandates the appeal and provides that the action is inoperative pending it. Absent that, an agency cannot invent an exhaustion requirement by regulation alone.
Character: where it applies, a mandatory statutory limit — not jurisdictional.
Finality is a separate gate and is not the same question. A decision can be exhausted and still not final, or final and not exhausted.
Who can be sued — and who cannot
The agency, or the officer in an official capacity.
Standing requires more than injury. Beyond Article III, the plaintiff must fall within the zone of interests the statute protects — a test that is not demanding but does exclude plaintiffs whose grievance is unrelated to what Congress was regulating.
No individual liability. And the immunity waiver stops at money damages, so a plaintiff seeking compensation must look to the Federal Tort Claims Act or another statute entirely.
Common defenses
No final agency action — the most common and most effective.
Committed to agency discretion by law, especially for non-enforcement decisions.
Statutory preclusion of review.
No standing, or outside the zone of interests.
Unripeness — the classic framework asks whether the issue is fit for review and what hardship withholding review would cause.
The action was reasonable, on the merits.
What the claim pays
Vacatur and remand — the ordinary remedy. The rule is set aside and the agency gets to try again.
Injunctive and declaratory relief.
No money damages. The statute's own waiver excludes them.
No jury. Review is on the record.
Fees under the Equal Access to Justice Act are available to a prevailing party where the government's position was not substantially justified — a real recovery route in these cases, and one worth knowing about because the government loses a meaningful share of them.
What people get wrong
"Courts defer to the agency's reasonable interpretation of the statute." Not since Loper Bright. Courts now decide statutory meaning independently.
"The APA has its own statute of limitations." It does not — it borrows the general six-year period for suits against the United States.
"I'm too late, the rule is thirty years old." Not necessarily, after Corner Post. Your clock runs from when the rule injured you.
"Any agency letter is final agency action." Rarely. It must consummate the decisionmaking process and determine rights or obligations.
"I can get damages." Not under this statute.
"I have to appeal within the agency first." Only if a statute or rule requires it and stays the action meanwhile.
Where it came from
The APA was enacted in 1946, a post-New Deal settlement between an executive branch that had grown enormously and a Congress that wanted its exercise of power reviewable. Its basic architecture — notice-and-comment rulemaking, a record, arbitrary-and-capricious review — has been stable ever since.
What has not been stable is how much independent judgment courts bring to it. For forty years, Chevron directed courts to accept any reasonable agency reading of an ambiguous statute. Loper Bright ended that in 2024, and Corner Post widened the window to bring the challenge.
Worth being precise about one thing: neither is a case of Congress overriding the Supreme Court. Loper Bright is the Court overruling itself. Bills to reverse Corner Post were introduced and not enacted — pending legislative activity, not law.
Common questions
Do courts still defer to an agency's interpretation of a statute?
No. Loper Bright Enterprises v. Raimondo overruled Chevron in 2024. Courts exercise independent judgment on what a statute means, even where it is ambiguous. An agency's view can persuade but does not bind.
How long do I have to challenge a federal regulation?
Six years by default, unless a specific review statute sets something shorter. After Corner Post, your six years runs from when the rule first injured you — not from when it was issued.
Do I have to appeal within the agency before going to court?
Only if a statute or agency rule requires it and makes the decision inoperative while the appeal is pending. Otherwise you may sue directly.
Can I get money damages from the agency?
No. The APA's waiver of sovereign immunity covers relief other than money damages. Damages claims run through the Federal Tort Claims Act or another statute.
What counts as "final agency action"?
The action must both consummate the agency's decisionmaking and determine rights or obligations, or produce legal consequences. Preliminary steps, guidance, and staff correspondence usually do not qualify.
