The Administrative State Explained: Agencies, Rulemaking, and Democratic Control
The federal government that Americans interact with most directly is not Congress or the president or the courts but the administrative state: the vast network of agencies, bureaus, and commissions that implement federal law. Understanding how that system works — and how it is controlled — is essential for making sense of regulatory politics.
Published June 26, 2026Congress passes statutes. But statutes, even detailed ones, cannot anticipate every situation that arises in their implementation. The Occupational Safety and Health Act tells the agency it creates to set safety standards that are “reasonably necessary or appropriate” to protect workers. The Clean Air Act directs the EPA to regulate air pollutants that “endanger public health or welfare.” These standards require expert judgment, technical analysis, and ongoing updating as conditions change. Congress delegates that judgment to agencies, and the rules those agencies issue carry the force of law.
The rulemaking process
When a federal agency wants to issue a significant rule, it must generally follow a process set out in the Administrative Procedure Act of 1946. The agency publishes a Notice of Proposed Rulemaking in the Federal Register, describing the proposed rule and the legal authority for it. A public comment period follows, typically lasting sixty to ninety days, during which any person or organization can submit written comments. The agency must genuinely consider those comments, and a final rule that departs from the proposed rule in significant ways without adequate explanation can be invalidated in court.
After reviewing comments, the agency publishes the final rule, again with an explanation of how it considered public input and why the final rule is supported by the legal authority and the evidence. There is typically a period before the rule takes effect, during which Congress can use the Congressional Review Act to disapprove significant rules with a simple majority vote in both chambers and the president's signature — or over a veto.
This notice-and-comment process provides formal public participation in a form of lawmaking that receives far less public attention than congressional legislation. Industry groups, public interest organizations, academic institutions, and state governments regularly submit detailed comments on proposed rules; ordinary citizens rarely do, but the legal right is there, and courts take seriously whether agencies adequately addressed substantive comments.
Judicial review and Chevron deference
When regulated parties disagree with a final rule, they can challenge it in federal court. Courts review whether the agency acted within its statutory authority, whether the rule is arbitrary or capricious, and whether the agency followed proper procedures. The arbitrary-and-capricious standard requires agencies to provide a reasoned explanation for their decisions based on evidence in the record; a rule that ignores contrary evidence or provides no rational basis can be struck down.
For decades, courts applied a doctrine known as Chevron deference to questions of whether an agency's interpretation of an ambiguous statute was permissible. Under Chevron, if a statute was ambiguous and the agency's interpretation was reasonable, courts deferred to the agency rather than substituting their own interpretation. This doctrine gave agencies significant latitude to fill gaps in statutory language. In 2024, the Supreme Court overruled Chevron in Loper Bright Enterprises v. Raimondo, directing courts to exercise independent judgment on questions of statutory interpretation rather than deferring to agency readings. The practical consequences of that shift — how it changes judicial scrutiny of agency rules and which rules become more vulnerable to challenge — are still being worked out in lower courts.
Who controls the agencies
Executive branch agencies are headed by officials appointed by the president and confirmed by the Senate. The president can generally remove heads of executive agencies at will, giving the White House direct influence over agency priorities and regulatory philosophy. Independent agencies — such as the Federal Communications Commission, the Securities and Exchange Commission, and the Federal Trade Commission — have commissioners with fixed terms who can be removed only for cause, providing some insulation from direct presidential control, though the scope of that protection has itself been the subject of litigation.
The Office of Information and Regulatory Affairs, housed within the Office of Management and Budget, reviews significant regulations before they are finalized and can return them to agencies for reconsideration. This review process gives the White House another mechanism for coordinating regulatory policy across agencies with different missions and political histories.
The scale of the administrative state
The federal government employs roughly two million civilian workers, spread across hundreds of agencies and sub-agencies. Agencies collectively issue thousands of final rules each year, though most are routine technical or ministerial updates; major economically significant rules are a much smaller share. The Code of Federal Regulations, which compiles all standing federal regulations, runs to tens of thousands of pages.
This scale is why the administrative state generates persistent political controversy. Conservatives have long argued that Congress has delegated too much lawmaking authority to unelected bureaucrats, violating the Constitution's vesting of legislative power in Congress. Progressives have generally defended administrative expertise as necessary for governing a complex modern economy but have sometimes argued that agencies are too deferential to the industries they regulate. The debate over who should control the administrative state — the president, Congress, the courts, or expert agencies insulated from short-term political pressure — is one of the most durable structural arguments in American constitutional politics.
For citizens, the practical implication is that regulatory decisions made in federal agencies often have more direct impact on daily life than the legislation that created those agencies. Knowing how to participate in rulemaking, how to challenge rules in court, and how agency leadership changes with administrations provides a more complete picture of how American law actually gets made.
