Why agencies make policy after Congress acts

UNIT 2 · INSTITUTIONS

CHAPTER 17

Congress often enacts broad policy and leaves technical details to administrative agencies. A statute may set the purpose and broad limits, then leave an agency to define eligibility, safety standards, reporting rules, enforcement priorities, or hundreds of other details. Those choices can change what a law means in daily life even though the agency never voted on the original bill.

Following one statute through that process, from delegation to a final rule to review, shows where the bureaucracy’s real policymaking power comes from.

CONGRESS CANNOT WRITE EVERY ADMINISTRATIVE DETAIL

A statute setting a broad goal, such as reducing a specific pollutant or ensuring workplace safety, cannot realistically specify every technical standard a regulated industry would need to follow. Congress delegates that technical work to the agency with relevant expertise, whether a department, an independent agency, or a regulatory commission, while retaining the statute’s basic purpose and legal boundaries.

WHERE DISCRETION COMES FROM

Discretion exists because the delegating statute leaves gaps, whether through general language, undefined terms, or unaddressed situations Congress did not anticipate. Agencies fill those gaps using specialized staff expertise that most members of Congress and their staff do not have. Discretion is not unlimited: an agency’s rule still has to connect back to authority the statute granted.

RULEMAKING TURNS STATUTES INTO OPERATING RULES

For many legislative rules, federal agencies use notice-and-comment procedures: the agency publishes a proposed rule, often in the Federal Register, and accepts public comments. Regulated parties, advocacy groups, and individuals can submit comments providing evidence, objections, or alternative approaches. The agency considers significant comments and issues a final rule, which then carries the force of law within the statute’s boundaries. Some categories of rules and some statutory schemes use different procedures or exceptions.

Public comments supply evidence and arguments for the agency to weigh; the process is reasoned administrative decision-making, not a vote count. An agency is not required to adopt whichever position receives the largest number of comments.

HOW COURTS REVIEW AGENCY RULES

A final rule can be challenged in court by a party affected by it, and a court then reviews whether the rule fits within the authority the statute granted. Current doctrine has courts interpret ambiguous statutory language independently rather than automatically deferring to an agency’s own interpretation of an ambiguous statute, a standard the Supreme Court adopted in Loper Bright Enterprises v. Raimondo in 2024, overruling the older Chevron deference framework. An agency’s technical expertise can still inform a court’s independent interpretation, but the court itself decides what an ambiguous statute means.

WHY EXPERTISE CREATES INFLUENCE

Specialized knowledge gives agencies influence well beyond the formal rulemaking process. Members of Congress, judges, and the public routinely rely on agency expertise to understand a technical field, which means the agency’s framing of a problem can shape a policy conversation even before any formal rule is proposed.

HOW CONGRESS AND PRESIDENTS TRY TO CONTROL AGENCIES

Congress controls agency funding through appropriations, conducts oversight through hearings and investigations, can rewrite the statute an agency operates under, and confirms many senior agency officials through the Senate. Presidents appoint agency leadership, direct policy priorities through the Office of Management and Budget’s review of proposed rules, and can issue executive orders shaping how agencies carry out existing statutes. Both branches use these tools continuously, not only when a rule becomes controversial.

TRACING A RULE FROM STATUTE TO REVIEW

Rulemaking moves through three recognizable stages, and the three descriptions below correspond to them out of order. Sort out which stage is which first.

Stage description 1. Congress passes a law directing an agency to set safety standards for a new category of consumer product, without specifying the exact standards.

Stage: delegation. The statute sets the goal and leaves technical standard-setting to agency discretion.

Stage description 2. The agency publishes a draft standard and accepts public comments for sixty days before finalizing it.

Stage: notice-and-comment rulemaking. The proposed rule and comment period precede the final rule.

Stage description 3. A manufacturer challenges the final rule in court, arguing the agency’s reading of the statute goes beyond what Congress authorized.

Stage: judicial review. The court independently interprets the statute’s meaning under the current Loper Bright standard rather than automatically deferring to the agency’s reading.

HOW BUREAUCRATIC ORGANIZATION SHAPES POLICY

The federal bureaucracy includes executive departments, agencies, commissions, and government corporations. These organizations carry policy into practice by writing and enforcing regulations, administering programs, issuing fines or other sanctions when statutes permit, and supplying testimony and technical information to Congress.

An iron triangle is a durable relationship among a congressional committee or subcommittee, a bureaucratic agency, and an interest group with a continuing stake in the same policy area. Each participant can supply something the others value: legislators provide authorization and funding, agencies provide implementation and expertise, and interest groups provide information and political support. An issue network is broader and less stable. It is a temporary or shifting coalition of officials, agencies, experts, advocacy groups, businesses, and other participants who come together around a particular issue or agenda.

The civil service relies primarily on a merit system, in which career hiring and promotion are based on qualifications, professionalism, specialization, and political neutrality. Political patronage works differently: some government positions are filled through political appointment because elected leaders are permitted to choose officials who support their policy agenda. AP questions often test the difference between neutral career administration and political appointment.

Required term	What students should know
Department / agency / commission / government corporation	All are forms of federal bureaucratic organization. The specific legal structure varies, but each can participate in administering public policy.
Regulation	A rule developed and enforced by an agency under authority delegated by statute.
Fine	A monetary sanction an agency may impose when legally authorized.
Testimony before Congress	A way agencies provide expertise and answer to legislative oversight.
Iron triangle	Durable committee-agency-interest-group relationship in a policy area.
Issue network	Broader and more temporary coalition organized around an issue or agenda.
Merit system	Career hiring and promotion based chiefly on qualifications, specialization, professionalism, and neutrality.
Political patronage	Political appointment to government positions based on elected leadership and political control rather than ordinary career-merit selection.

QUESTIONS TO ANSWER WITHOUT NOTES

1. Why does Congress delegate technical rulemaking authority to agencies?

Because a statute cannot realistically specify every technical detail, and agencies have specialized expertise Congress generally lacks.

2. List the basic steps of notice-and-comment rulemaking in order.

A proposed rule is published, the public submits comments during a comment period, the agency reviews significant comments, and a final rule is issued.

3. Must an agency adopt the position supported by the most public comments?

No. Rulemaking is reasoned decision-making based on evidence and argument, not a vote count.

4. What standard do courts currently use when a statute an agency administers is ambiguous?

Courts interpret the ambiguous language independently, the standard set in Loper Bright Enterprises v. Raimondo (2024), which overruled the older Chevron deference framework.

5. Does Chevron deference still control how courts review agency interpretations of ambiguous statutes?

No. Chevron deference was overruled by Loper Bright Enterprises v. Raimondo in 2024.

6. List three tools Congress uses to control agencies after delegating authority.

Appropriations, oversight hearings and investigations, and Senate confirmation of senior officials (rewriting the authorizing statute is also acceptable).

7. How does a president influence agency policy beyond appointing agency leadership?

Through Office of Management and Budget review of proposed rules and executive orders directing how agencies carry out existing statutes.

8. A Senate committee, an aviation agency, and an airline trade association work together repeatedly on the same regulatory area. Which concept fits best?

Iron triangle. The relationship is durable and links a congressional committee, a bureaucratic agency, and an interest group.

9. Scientists are hired into career agency positions after a competitive qualifications process

and remain through changes in presidential administrations. Which personnel principle is

illustrated?

The merit system, which emphasizes qualifications, specialization, professionalism, and political neutrality.

10. A short-lived coalition of researchers, agency staff, companies, legislators, and advocacy groups forms around a new artificial-intelligence bill. Which concept fits best?

Issue network. The coalition is broad, issue-specific, and less stable than an iron triangle.
