Key Facts
- Federal level: The Administrative Procedure Act supplies default procedures for federal agency rulemaking, adjudication, and judicial review.
- Federal level: Informal rulemaking under 5 U.S.C. § 553 generally involves public notice, an opportunity to comment, and a final rule with a statement of basis and purpose.
- Federal level: Section 553 contains exceptions, including categories involving military or foreign affairs and agency management or property, as well as a good-cause exception.
- Federal level: A court reviewing agency action may set it aside on grounds listed in 5 U.S.C. § 706, including arbitrary or capricious action, excess of statutory authority, or failure to follow required procedure.
- Federal level: The APA is a framework, not the source of every agency power; an agency needs substantive authority from another statute.
The Administrative Procedure Act, usually called the APA, is the central federal statute governing how executive agencies make many rules, decide certain cases, and face review in court. Enacted in 1946 and now codified mainly in Titles 5 and 5’s judicial-review provisions, it creates common procedures across agencies without making every agency proceeding identical.
The APA does not itself give an agency authority to regulate any subject it chooses. Congress normally supplies that authority in a program-specific statute. The APA then provides default procedural rules unless another statute changes or supplements them.
The APA defines the basic pieces of agency action
Section 551 defines terms that organize the statute. A “rule” is an agency statement of general or particular applicability and future effect designed to implement, interpret, or prescribe law or policy. “Rulemaking” is the agency process for formulating, amending, or repealing a rule.
An “order” is a final disposition in an agency matter other than rulemaking, and “adjudication” is the process for formulating an order. These definitions explain why issuing a regulation differs from deciding a license, benefit, enforcement, or other individual matter.
Notice-and-comment rulemaking is the familiar model
Section 553 describes the process often called informal or notice-and-comment rulemaking. An agency generally publishes a notice of proposed rulemaking in the Federal Register. The notice identifies the time, place, and nature of the proceeding, cites the legal authority, and describes the proposed rule’s terms or subjects and issues.
Interested people must receive an opportunity to submit written data, views, or arguments. After considering relevant material, the agency incorporates in the adopted rule a concise general statement of its basis and purpose. Publication of a final rule and its effective date are separate from publication of the proposal.
The public docket can contain comments, studies, meeting records, economic analysis, and other material. A comment is most useful to the administrative process when it addresses the proposal’s evidence, legal authority, costs, benefits, implementation, or alternatives rather than merely recording support or opposition.
Not every rule uses ordinary notice and comment
Section 553 excludes matters involving military or foreign affairs functions and matters relating to agency management or personnel or to public property, loans, grants, benefits, or contracts. It also generally exempts interpretive rules, general policy statements, and agency rules of organization, procedure, or practice from the notice-and-comment requirement.
An agency may dispense with notice and comment for good cause when it finds that the procedure would be impracticable, unnecessary, or contrary to the public interest and incorporates the finding and reasons in the rule. Good cause is a statutory exception, not a general license to bypass participation whenever speed would be convenient.
Other statutes can require more procedure than the APA. Some rules use formal, on-the-record hearings under Sections 556 and 557. Congress can also impose specialized consultation, analysis, timing, or hearing requirements for a particular program.
Agency adjudication can be formal or informal
Section 554 governs adjudications that another statute requires to be determined on the record after an opportunity for an agency hearing. Sections 556 and 557 supply hearing and decision procedures, including rules for evidence, presiding officers, the record, and agency review.
Many agency decisions do not fall within formal adjudication. Their procedures may instead come from a program statute, agency regulations, constitutional due process, or other law. The label “administrative hearing” therefore does not by itself establish which APA provisions apply.
The APA also governs judicial review
Sections 701 through 706 address review of agency action. Review is generally available to a person suffering legal wrong or adversely affected within the meaning of a relevant statute, but review may be unavailable when a statute precludes it or action is committed to agency discretion by law.
Courts ordinarily review final agency action for which there is no other adequate remedy. Section 706 directs a reviewing court to decide legal questions and review the whole record or cited parts of it, while giving due account to prejudicial error.
The familiar “arbitrary and capricious” standard is one part of Section 706. The statute also directs courts to set aside action contrary to constitutional rights, beyond statutory authority, adopted without required procedure, unsupported by substantial evidence in specified proceedings, or unwarranted by the facts when trial de novo is authorized.
Proposed rules and final rules are different legal events
The Federal Register publishes proposed rules, final rules, notices, and presidential documents. A proposed rule announces possible regulatory text and invites participation; it usually does not create the final legal obligation described in the proposal.
A final rule states what the agency adopted, responds to significant issues, supplies final regulatory text, and identifies an effective date. The operative text is later organized in the Code of Federal Regulations. A rule can also be delayed, corrected, withdrawn, stayed, or invalidated, so publication history and current codification both matter.
The APA is therefore best understood as a map of federal agency process. It connects congressional authorization, agency explanation, public participation, the administrative record, and judicial review. A companion overview of federal regulation helps place these procedures within the broader system of statutes and agency rules.
