Judicial review of agency actions is the process by which a federal court examines a federal agency’s final decision and, if it finds the decision unlawful, sets it aside. The Administrative Procedure Act supplies the right to sue, the court’s standards, and the limits on what it can review. Getting a court to actually reach the merits requires clearing procedural gates first, meeting a filing deadline that is often very short, and understanding that in June 2024 the Supreme Court fundamentally changed how judges evaluate an agency’s reading of the law.
Where the Right to Sue Comes From
The APA, codified across Title 5 of the U.S. Code, is the backbone. Under 5 U.S.C. § 701, judicial review is available for most agency actions. There are two exceptions: a statute explicitly bars review, or Congress has committed the decision entirely to the agency’s discretion.1Office of the Law Revision Counsel. 5 USC 701 – Application; Definitions Courts read those exceptions narrowly. In Abbott Laboratories v. Gardner, the Supreme Court said the APA’s “generous review provisions” must be given a “hospitable” interpretation, and that only “clear and convincing evidence” of contrary legislative intent should block access.2Justia Law. Abbott Laboratories v. Gardner, 387 US 136 (1967)
Section 702 gives any person “suffering legal wrong because of agency action, or adversely affected or aggrieved” by it the right to review. The same section does something easy to overlook but essential: it waives the federal government’s sovereign immunity for suits seeking non-monetary relief. Without that waiver, most challenges would be blocked by the default rule that you cannot sue the United States without its consent. You can name the United States as a defendant and ask for injunctions or orders setting aside the unlawful action. You cannot use the APA to get money damages.3Office of the Law Revision Counsel. 5 USC 702 – Right of Review
Which court hears the case depends on what Congress said. Many statutes send challenges directly to a particular court of appeals, often the D.C. Circuit, which handles a disproportionate share of regulatory litigation. When no statute designates a specific court, the challenge defaults to federal district court under 28 U.S.C. § 1331, the general federal question jurisdiction statute.4Administrative Conference of the United States. Choice of Forum for Judicial Review of Agency Rules Filing in the wrong court can cost months, so pinning down the right forum is step one.
What You Have to Clear Before a Court Will Hear You
Several procedural gates stand between you and a decision on the merits. Fail any one and the case ends.
Standing
You must have suffered an actual or threatened injury, that injury must trace back to the agency’s action, and a ruling in your favor must be able to fix it. The injury has to be concrete and specific to you. A general belief that the government is acting unlawfully is not enough, and courts routinely dismiss cases where the complaint is shared dissatisfaction with policy rather than direct personal impact.5Legal Information Institute. Constitution Annotated – Standing Requirement Overview
Exhaustion of Administrative Remedies
If the agency offers internal appeals, reconsideration, or a hearing process, you generally have to use them first. The idea is to let the agency fix its own mistakes before a court gets involved. Skipping available internal remedies usually means immediate dismissal. The rare exceptions involve situations where pursuing agency remedies would be futile, or where the agency’s process itself is the thing being challenged.
Ripeness
Courts will not step into a dispute that has not fully developed. Under Abbott Laboratories, judges weigh whether the legal issues are ready for decision and whether the parties will suffer real hardship if the court waits.6Legal Information Institute. Constitution Annotated – Overview of Ripeness Doctrine Challenging a draft rule that may never become final wastes judicial resources and interferes with the agency’s work before it is done.
Finality
Under 5 U.S.C. § 704, only “final agency action” is reviewable.7Office of the Law Revision Counsel. 5 USC 704 – Actions Reviewable An action is final when it marks the end of the agency’s decision-making process and creates direct legal consequences for you. Preliminary steps, tentative recommendations, and internal staff memos do not count. A published regulation or a binding order does.
Mootness
The dispute has to stay alive. If the agency withdraws the challenged rule or reverses course, the court may conclude there is nothing left to decide. The voluntary cessation doctrine keeps agencies from gaming this. A party cannot moot a case simply by ending the challenged behavior once sued, because that would invite a cycle of stopping when sued and restarting after dismissal. The party claiming mootness has the heavy burden of showing it is “absolutely clear” the challenged conduct will not recur.8Legal Information Institute. Exceptions to Mootness – Voluntary Cessation Doctrine
How Long You Have to File
Deadlines in administrative law vary widely, and missing one is the fastest way to lose a winnable case. Many agency-specific statutes impose short windows for filing a petition for review, commonly 30 to 60 days after the agency issues its final decision. The exact period depends on which agency and which statute applies. The Merit Systems Protection Board, for example, requires petitions within 35 days of the initial decision’s issuance.9eCFR. 5 CFR Part 1201 Subpart C – Petitions for Review of Initial Decisions These deadlines are strict, and courts rarely extend them.
When no agency-specific statute sets a deadline, the default is the six-year statute of limitations for civil actions against the United States under 28 U.S.C. § 2401(a).10Office of the Law Revision Counsel. 28 USC 2401 – Time for Commencing Action Against United States In 2024, the Supreme Court’s decision in Corner Post, Inc. v. Board of Governors clarified that the six-year clock does not start when the agency acts. It starts when your cause of action first accrues, meaning when you actually suffer an injury from the final agency action.11Supreme Court of the United States. Corner Post, Inc. v. Board of Governors of the Federal Reserve System A business that did not exist when a regulation was issued can still challenge it within six years of being harmed by it. Older regulations once treated as immune from attack may now be vulnerable to petitioners who were only recently injured.
How Courts Judge the Agency
Section 706 of the APA lays out the standards courts apply when reviewing an agency decision.12Office of the Law Revision Counsel. 5 USC 706 – Scope of Review Which standard governs depends on the type of decision.
Arbitrary and Capricious Review
This is the most commonly applied standard, covering informal agency actions and general rulemaking. The court asks whether the agency examined the relevant information, considered important aspects of the problem, and drew a rational connection between the facts and its decision. It is deferential, but it is not a rubber stamp. The question is whether the decision fell within the range of reasonable choices, not whether it was the best choice. If the agency ignored significant evidence, relied on factors Congress did not intend, or offered an explanation that contradicts the record, the decision can be vacated.
Substantial Evidence
When an agency conducts a formal hearing with testimony and an evidentiary record, the court applies a stricter test. It examines the entire record to decide whether a reasonable person could accept the evidence as adequate to support the agency’s conclusion. This is harder for the agency to meet than arbitrary-and-capricious review, but the court still does not re-weigh the evidence or substitute its own judgment. The question is whether the record, taken as a whole, could support the result.
Independent Judgment on Legal Questions
The biggest recent change concerns how courts handle an agency’s reading of the statutes it administers. For 40 years, the Chevron doctrine required courts to defer to an agency’s “permissible” reading of an ambiguous statute. In June 2024, the Supreme Court overruled Chevron in Loper Bright Enterprises v. Raimondo. The Court held that the APA requires courts to exercise “independent judgment in deciding whether an agency has acted within its statutory authority,” and that an agency’s interpretation “cannot bind a court.”13Supreme Court of the United States. Loper Bright Enterprises v. Raimondo
Courts can still consider what the agency thinks. Under the older Skidmore framework, which survived Loper Bright, a court may give weight to an agency’s interpretation based on its persuasiveness, the thoroughness of its reasoning, and its consistency over time. That weight is earned, not automatic. An agency that has flip-flopped or adopted a novel reading to support a new policy initiative will get less deference than one that has consistently applied the same interpretation for decades.
The Major Questions Doctrine
A separate brake applies when an agency claims authority over an issue of vast economic or political significance. The major questions doctrine requires the agency to point to “clear congressional authorization” for that authority.14Supreme Court of the United States. West Virginia v. EPA A vague or broadly worded statute is not enough. The Supreme Court applied this in West Virginia v. EPA to strike down an EPA emissions regulation, concluding that Congress had not clearly authorized the agency to restructure the nation’s energy mix. Agencies pursuing ambitious regulatory agendas need to show that Congress specifically gave them permission, not that a plausible reading of the statute could support it.
Review Is Confined to the Administrative Record
Whichever standard applies, courts almost always confine their review to the administrative record: the documents, data, public comments, expert reports, and hearing transcripts the agency considered when making its decision. New evidence is rarely allowed. The court judges whether the agency’s reasoning held together based on what the agency knew at the time, not what someone digs up afterward. That makes the record the center of gravity for the whole case.
Preparing the Record Before You File
The agency is technically responsible for compiling and filing the record, but petitioners who sit back and wait make a mistake. You need to know what is in that record, and what might be missing, before you file. Start with any public comments, hearing transcripts, and agency correspondence tied to the decision. The agency’s docket number is the key to tracking the full history of the proceeding, and it appears on the final order or published regulation. If you submitted comments or testimony during the rulemaking or adjudication, your materials should already be part of the record.
The Freedom of Information Act is an additional tool. Under 5 U.S.C. § 552, federal agencies must disclose records on written request, with nine statutory exemptions covering areas like classified information, trade secrets, privileged internal deliberations, and personal privacy. Agencies must respond within 20 business days, though complex requests often take longer.15Office of the Law Revision Counsel. 5 USC 552 – Public Information; Agency Rules, Opinions, Orders, Records, and Proceedings A targeted FOIA request can surface internal analyses, emails, and draft documents that show how the agency actually reached its conclusion. Filing well before you petition gives you time to identify gaps or errors that can anchor your legal arguments. If the agency withholds information, it must show that disclosure would cause foreseeable harm to a protected interest.
Filing the Petition for Review
When a statute directs review to a court of appeals, the case begins with a petition for review governed by Federal Rule of Appellate Procedure 15. The petition must name every party seeking review, identify the agency as the respondent, and specify the order or regulation being challenged by title, date, and docket number. Vague references to the agency’s general conduct will not do. The petition must be filed “within the time prescribed by law,” so the specific deadline comes from the statute that authorizes review of that agency’s decisions.16Legal Information Institute. Federal Rules of Appellate Procedure – Rule 15
Most federal courts use CM/ECF, the Case Management/Electronic Case Files system, for electronic filing.17United States Courts. Electronic Filing (CM/ECF) The filing fee for a petition for review or an original proceeding in a federal court of appeals is $600.18United States Court of Appeals – Eleventh Circuit. Fee Schedules Fee waivers are available for petitioners who cannot afford it.
After filing, you serve the petition on the agency. Some statutes also require service on the Attorney General of the United States, so check the specific statute authorizing review. Once served, the agency has 40 days to file the administrative record with the court unless the governing statute sets a different timeline.19United States Court of Appeals – Second Circuit. FRAP 17 – Filing the Record The court then issues a scheduling order setting deadlines for briefs and oral argument.
Stopping the Rule While You Litigate
Filing a petition does not automatically pause the agency’s action. If the regulation or order will cause irreparable harm during the case, you may need emergency relief.
Under 5 U.S.C. § 705, the agency itself can postpone the effective date of its own action pending judicial review when “justice so requires.”20Office of the Law Revision Counsel. 5 USC 705 – Relief Pending Review In practice, agencies rarely delay their own rules voluntarily. When the agency will not act, the petitioner can ask the court for a preliminary injunction or a stay.
Courts weigh four factors: whether the petitioner is likely to succeed on the merits, whether the petitioner will suffer irreparable harm without relief, whether the balance of hardships favors the petitioner, and whether a stay or injunction serves the public interest. All four matter, and weakness on one can sink the request. Irreparable harm tends to be the sticking point. Pure economic losses often do not qualify, because money damages can theoretically be calculated later. Harms that are difficult to undo, like environmental damage or the loss of constitutional rights, carry more weight.
What a Win Looks Like: Vacatur or Remand
If the court finds the agency action unlawful, it has two main remedies. The first is vacatur. The regulation or order is set aside as if it never existed, and the agency has to start over.21Administrative Conference of the United States. The Unusual Remedy of Remand Without Vacatur
The second is remand without vacatur. The court sends the decision back for further explanation or correction but leaves the existing rule in place during the interim. Courts use a two-factor test to decide between the remedies: how serious the agency’s error was and whether the agency could fix it on remand, and how disruptive vacatur would be. If striking down a regulation would create a dangerous regulatory gap, destabilize a market, or cut off public benefits, courts are more inclined to leave the rule in place while the agency addresses the deficiency. Either factor can be decisive on its own.
Remand without vacatur has become increasingly common, particularly for complex regulations where the error is procedural rather than substantive. The agency might have failed to explain its reasoning adequately or neglected to respond to significant public comments. In those cases, the underlying policy may be defensible, and the court gives the agency a second chance to build a proper record instead of blowing up the regulatory framework.
Recovering Attorney Fees
Challenging a federal agency is expensive. Attorney fees commonly run several hundred dollars per hour. The Equal Access to Justice Act, codified at 28 U.S.C. § 2412, provides a mechanism for recovering those costs if you prevail and the government’s position was not “substantially justified.”22Office of the Law Revision Counsel. 28 USC 2412 – Costs and Fees
Eligibility is limited by net worth and size. Individuals must have a net worth below $2 million at the time of filing. Businesses, partnerships, and organizations must have a net worth below $7 million and no more than 500 employees. Tax-exempt organizations under 26 U.S.C. § 501(c)(3) and certain cooperative associations can qualify regardless of net worth, provided they have fewer than 500 employees. Net worth and employee count are measured as of the date the case was filed, and affiliates are aggregated.
The government can defeat an EAJA claim by showing its position in the underlying case was substantially justified, even if it ultimately lost. That is a lower bar than proving the government was right. If the agency’s legal argument was reasonable and grounded in existing law, the court may deny fees even though the petitioner prevailed. EAJA applications must typically be filed within 30 days of the final judgment becoming non-appealable. Wait too long after winning and you can forfeit the right to recover fees entirely.
