What Is an Administrative Agency?
Introduction
The modern American government does far more than pass statutes and prosecute crimes.
Government regulates financial markets, workplace safety, environmental protection, communications, transportation, food and drugs, immigration, labor relations, consumer protection, energy, securities, and countless other areas of public life.
Congress cannot personally administer all of these programs.
That is why the federal government relies on administrative agencies.
An administrative agency is a governmental body created or authorized by law to administer particular statutes, programs, or areas of public policy. Agencies may develop regulations, issue licenses, investigate violations, enforce legal requirements, conduct administrative proceedings, and perform many other governmental functions.
Cornell Law School’s Legal Information Institute defines an administrative agency as a government body authorized to implement legislative directives by developing more precise and technical rules than would generally be possible through legislation alone. Many agencies also have enforcement responsibilities. Cornell Wex: Administrative Agency
Administrative agencies are therefore one of the principal mechanisms through which legislation becomes functioning government.
But an agency is not simply a department that “does government work.”
An agency possesses legal authority.
That authority has a source, a scope, and limits.
Understanding administrative agencies therefore requires answering several fundamental questions:
- What exactly is an administrative agency?
- Why does government need agencies?
- Who creates them?
- Where does their authority come from?
- What powers do they exercise?
- Are agencies part of the legislative, executive, or judicial branch?
- What is the difference between executive and independent agencies?
- Can agencies make law?
- Can agencies enforce the law?
- Can agencies act like courts?
- Who controls agencies?
- Who reviews their decisions?
- What happens when an agency exceeds its authority?
These questions form the foundation of administrative law.
1. The Basic Definition
In simple terms:
An administrative agency is a governmental institution authorized by law to administer and implement a particular area of government policy.
The word administer is important.
An agency generally does not begin with unlimited governmental power.
Congress establishes a statutory framework and assigns responsibilities to an agency.
The agency then operates within that framework.
For example, Congress may enact legislation regulating securities markets and establish the Securities and Exchange Commission to administer that statutory system.
Congress may enact environmental statutes and assign implementation responsibilities to the Environmental Protection Agency.
Congress may establish rules governing communications and authorize the Federal Communications Commission to administer them.
The agency becomes the institutional mechanism through which the statutory program operates.
2. Why Do Administrative Agencies Exist?
The simplest answer is that modern government is too complex for Congress to administer every law itself.
Legislation usually establishes general rules.
Administration requires detailed decisions.
Consider environmental regulation.
Congress might determine that certain pollutants must be controlled.
But Congress cannot realistically write a separate statute specifying:
- the precise scientific measurement for every pollutant;
- the appropriate technical standard for every facility;
- every reporting requirement;
- every inspection procedure;
- every compliance deadline;
- every technological development;
- and every possible factual circumstance.
An agency can employ scientists, economists, engineers, lawyers, investigators, and other specialists to administer the regulatory system.
This is one reason administrative government developed.
Administrative agencies provide institutional expertise and administrative capacity.
3. Agencies Translate General Laws Into Detailed Administration
Legislation often establishes broad objectives.
Agencies then make those objectives operational.
Suppose Congress passes a statute requiring the government to protect consumers from a particular form of deceptive commercial conduct.
The statute may establish the basic prohibition.
An agency might then:
- define technical requirements;
- issue regulations;
- investigate suspected violations;
- collect information;
- conduct administrative proceedings;
- issue enforcement orders; and
- refer certain matters to courts or other authorities.
The agency is therefore part of the process through which a general legislative command becomes a functioning regulatory system.
This is one of the defining characteristics of administrative government.
4. Agencies Do Not Have Inherent Unlimited Power
One of the most important principles in administrative law is that an agency does not possess governmental authority simply because it is called an agency.
Its powers must have a lawful source.
Usually, the agency’s authority comes from:
- the Constitution;
- an act of Congress;
- an agency’s organic or enabling statute;
- other applicable federal statutes;
- valid regulations; or
- authority properly delegated by Congress.
Cornell’s overview of administrative law emphasizes that agencies receive delegated authority from Congress and must operate within constitutional and statutory parameters.
This produces a fundamental administrative-law question:
What legal authority permits the agency to do this?
That question should be asked whenever an agency exercises significant governmental power.
5. The Organic Statute
The statute that creates an agency or establishes its basic authority is often called its organic statute or enabling statute.
This statute can determine:
- the agency’s purpose;
- its jurisdiction;
- its powers;
- its responsibilities;
- its organizational structure;
- appointment provisions;
- enforcement authority;
- rulemaking authority;
- adjudicatory authority; and
- limitations on its actions.
The organic statute is therefore the starting point for understanding an agency.
Before asking what an agency may do, a lawyer should ordinarily ask:
What does the agency’s organic statute authorize it to do?
The answer establishes the legal foundation for everything that follows.
6. Administrative Agencies and the Constitution
Administrative agencies operate within the constitutional structure of the United States.
The Constitution establishes three principal branches:
- Congress;
- the executive branch; and
- the federal judiciary.
Administrative agencies interact with all three.
Congress creates agencies and delegates authority to them.
The executive branch generally administers federal law through executive agencies and presidentially supervised officials.
Courts review agency action when appropriate.
This creates a complicated constitutional relationship.
An agency may perform functions that resemble legislation, executive administration, and adjudication.
That does not automatically mean the agency is unconstitutional.
The constitutional question is whether the agency’s powers and structure remain within constitutionally permissible boundaries.
7. Are Administrative Agencies a Fourth Branch?
No.
The Constitution does not recognize administrative agencies as a separate fourth branch of government.
Some agencies possess unusual combinations of governmental functions, and some independent agencies are deliberately insulated from certain forms of presidential control.
But these agencies remain part of the broader constitutional structure.
The idea of a “fourth branch” is therefore more useful as a description of the administrative state’s complexity than as a constitutional classification.
The better question is:
Which branch constitutionally controls or supervises the relevant governmental function, and what limitations apply to the agency exercising it?
That question connects agency structure to separation of powers.
8. Executive Agencies
Many federal agencies operate within the executive branch.
Examples include agencies and departments such as:
- the Department of Justice;
- the Department of Defense;
- the Department of Labor;
- the Department of Transportation; and
- the Environmental Protection Agency.
Executive agencies generally operate under presidential supervision through the constitutional and statutory structures governing the executive branch.
The President’s role matters because Article II vests executive power in the President.
This creates a chain of political accountability.
At a simplified level:
Congress → creates statutory authority
President → oversees execution of federal law
Agency → administers the statutory program
Courts → review lawful boundaries when appropriate
This structure is not absolute, but it provides a useful starting framework.
9. Independent Agencies
Not every administrative agency is structured as an ordinary executive agency.
Some agencies are traditionally described as independent agencies.
Examples include:
- the Federal Trade Commission;
- the Securities and Exchange Commission;
- the Federal Communications Commission; and
- the National Labor Relations Board.
Independent agencies may have statutory protections designed to reduce direct presidential control.
This can serve institutional purposes.
Congress may conclude that certain regulatory decisions should have some insulation from immediate political pressure.
But independence raises constitutional questions concerning presidential control and accountability.
The Supreme Court has therefore treated agency structure—including restrictions on removal—as an important separation-of-powers issue.
10. Why Agency Independence Matters
Suppose Congress creates an agency and gives its officials substantial authority.
If those officials are completely insulated from presidential supervision, an important question arises:
Who is constitutionally accountable for their exercise of executive power?
The Supreme Court has addressed these issues in cases such as Free Enterprise Fund v. Public Company Accounting Oversight Board and Seila Law LLC v. Consumer Financial Protection Bureau.
The constitutional analysis can depend upon:
- the agency’s structure;
- the official’s functions;
- appointment mechanisms;
- removal protections;
- the degree of presidential control; and
- the nature of the authority being exercised.
Thus, agency structure is not merely an organizational matter.
It can be a constitutional matter.
11. What Do Administrative Agencies Actually Do?
Administrative agencies perform many different functions.
The most important include:
Rulemaking
Agencies may issue regulations when Congress has delegated appropriate rulemaking authority.
Enforcement
Agencies may investigate violations and enforce statutes and regulations.
Adjudication
Agencies may conduct administrative proceedings and resolve disputes within their statutory jurisdiction.
Licensing
Agencies may issue, deny, suspend, or revoke licenses and permits.
Inspection
Agencies may inspect regulated entities under applicable statutory and constitutional rules.
Investigation
Agencies may gather information and investigate possible violations.
Guidance
Agencies may publish interpretations, policy statements, manuals, notices, and other guidance explaining how they administer laws.
Administration
Agencies may operate government programs, distribute benefits, maintain records, and perform other statutory responsibilities.
These functions explain why administrative agencies are so important to everyday government.
12. Rulemaking
One of the most visible powers of administrative agencies is rulemaking.
A regulation is a rule issued by a governmental agency to govern conduct within the agency’s jurisdiction.
Congress may establish a broad statutory program and authorize an agency to develop detailed regulations.
For example, Congress may direct an agency to regulate workplace safety.
The agency may then develop detailed requirements concerning:
- equipment;
- inspections;
- reporting;
- workplace procedures;
- exposure limits;
- recordkeeping; and
- compliance.
These regulations can have substantial legal consequences.
But the agency’s rulemaking authority must remain within the statutory authority Congress granted.
13. Agencies Do Not Simply “Make Laws”
It is common to hear that administrative agencies “make laws.”
That phrase can be misleading.
Agencies can issue legislative rules with binding legal effect when Congress has lawfully delegated rulemaking authority.
But agencies are not constitutional legislatures.
Congress retains the legislative power vested in it by Article I.
The distinction matters because an agency cannot simply create any policy it considers desirable.
The agency must identify a lawful statutory foundation for the rule.
This is one reason administrative law repeatedly returns to the question of delegated authority.
14. Rulemaking Under the Administrative Procedure Act
The federal Administrative Procedure Act provides a major framework for federal agency procedures.
The APA governs, among other things:
- rulemaking;
- adjudication;
- administrative procedures; and
- judicial review.
Cornell’s Wex explains that the APA is codified principally at 5 U.S.C. §§ 551–559 and establishes important procedural rules governing federal administrative agencies.
For many legislative rules, the familiar process is notice-and-comment rulemaking.
Generally, an agency:
- proposes a rule;
- publishes notice;
- allows interested persons to submit comments;
- considers relevant comments;
- adopts a final rule; and
- provides an explanation for its action.
The exact procedure depends on the governing statute and the type of agency action involved.
15. Enforcement
Administrative agencies frequently have enforcement responsibilities.
An agency may:
- investigate suspected violations;
- request information;
- conduct inspections;
- issue administrative orders;
- initiate administrative proceedings;
- impose authorized civil penalties;
- suspend or revoke licenses; or
- refer matters for judicial enforcement.
The agency’s enforcement power depends on statutory authority.
An agency cannot impose a sanction merely because it believes a sanction would be useful.
There must be legal authority supporting the enforcement action.
16. Administrative Investigations
Investigation is often an essential part of agency administration.
Agencies may need information to determine whether regulated parties are complying with federal law.
Depending on the statute, an agency may have authority to:
- issue subpoenas;
- request documents;
- conduct inspections;
- interview witnesses;
- require reports;
- examine records; or
- obtain information through other lawful procedures.
But administrative investigations are subject to legal limitations.
Constitutional protections, statutory requirements, and judicial review can restrict the methods an agency may use.
17. Administrative Adjudication
Agencies may also adjudicate disputes.
An administrative adjudication resembles a judicial proceeding in certain respects.
There may be:
- a complaint;
- opposing parties;
- evidence;
- testimony;
- legal arguments;
- findings of fact;
- conclusions of law; and
- an administrative decision.
Administrative Law Judges may preside over certain proceedings.
Cornell Wex explains that an Administrative Law Judge is an independent hearing examiner who presides over administrative hearings and may receive evidence, take testimony, and make findings of fact or law, subject to applicable agency review structures.
But an administrative adjudication is not simply an ordinary federal court proceeding.
Its authority comes from the statutory administrative scheme.
18. Licensing
Many administrative agencies control access to regulated activities through licensing.
Licenses may be required for:
- professional practice;
- broadcasting;
- transportation;
- financial activities;
- environmental operations;
- immigration-related activities;
- commercial operations; or
- other regulated activities.
An agency may determine whether an applicant satisfies statutory and regulatory requirements.
Depending on the legal framework, the agency may also have authority to:
- suspend a license;
- revoke a license;
- impose conditions;
- deny renewal; or
- modify the scope of a license.
Because licensing can affect important interests, procedural safeguards may apply.
19. Agencies and Guidance
Not everything an agency publishes is a legally binding regulation.
Agencies frequently issue:
- guidance documents;
- interpretive rules;
- policy statements;
- advisory opinions;
- manuals;
- enforcement policies;
- FAQs; and
- compliance materials.
These documents can be extremely important in practice.
A regulated company may rely on agency guidance to understand how the agency approaches compliance.
But guidance generally differs from a legislative rule.
The distinction matters because an agency cannot necessarily impose legally binding obligations through a document that lacks the legal foundation or procedures required for a binding rule.
20. Administrative Agencies and Expertise
One of the principal arguments for administrative government is expertise.
Modern regulation often involves subjects that require specialized knowledge.
Examples include:
- securities markets;
- telecommunications;
- pharmaceuticals;
- aviation;
- nuclear safety;
- environmental science;
- financial regulation;
- labor economics; and
- technological systems.
Congress may establish broad statutory objectives while relying on agencies to apply specialized knowledge to complex problems.
This expertise can make administrative government more practical.
But expertise has an important limit:
Expertise does not equal legal authority.
An agency may understand a technical problem better than a court while still exceeding its statutory authority.
21. Agencies and Administrative Discretion
Agencies often receive some degree of administrative discretion.
A statute may give an agency several lawful options rather than requiring one precise result.
The agency might have discretion concerning:
- enforcement priorities;
- licensing decisions;
- regulatory standards;
- penalties;
- resource allocation;
- exemptions;
- timing; or
- technical implementation.
Discretion is necessary because legislation cannot predict every possible factual circumstance.
But discretion must remain within legal boundaries.
An agency cannot transform discretionary authority into unlimited authority.
22. Agencies and the Separation of Powers
Administrative agencies sit at the center of one of the most important constitutional debates in modern government.
Congress makes laws.
The executive branch executes them.
Courts interpret and apply them in cases and controversies.
Yet agencies may:
- formulate regulations;
- enforce those regulations;
- conduct administrative hearings; and
- interpret statutes and regulations.
This overlap raises separation-of-powers questions.
The existence of overlapping functions is not automatically unconstitutional.
The constitutional system permits substantial interaction among the branches.
The central questions are:
- Who delegated the power?
- What exactly was delegated?
- What constitutional limits apply?
- Who supervises the agency?
- What procedures govern its actions?
- Who reviews the agency’s decisions?
23. The Nondelegation Doctrine
The nondelegation doctrine is particularly relevant to administrative agencies.
Congress cannot simply transfer unlimited legislative power to administrative officials.
The traditional doctrine asks whether Congress has provided an intelligible principle to guide the exercise of delegated authority. Cornell Wex: Nondelegation Doctrine
This principle recognizes both sides of the problem.
Congress must be able to delegate enough authority for modern government to function.
But Congress cannot simply abandon its constitutional legislative responsibility.
Administrative agencies therefore operate within a system of delegated power.
24. The Administrative Procedure Act
The APA is one of the most important statutes in federal administrative law.
It establishes procedural requirements governing federal agencies and provides a framework for judicial review.
The APA addresses matters including:
- rulemaking;
- adjudication;
- agency procedure;
- publication;
- hearings;
- administrative records; and
- judicial review.
It does not create every federal agency.
Instead, it establishes a general procedural framework within which many federal agencies operate.
The agency’s own organic statute remains essential because it determines the particular substantive authority Congress gave that agency.
25. Agencies and Judicial Review
Administrative agencies are not the final authority on every legal question.
Courts may review agency action under applicable statutes and constitutional principles.
Judicial review can ask whether the agency:
- exceeded its statutory authority;
- violated the Constitution;
- followed required procedures;
- acted arbitrarily or capriciously;
- failed to explain its decision adequately;
- violated due process; or
- otherwise acted unlawfully.
Judicial review is therefore an important mechanism for controlling administrative power.
26. Loper Bright and Agency Interpretation
The relationship between agencies and courts changed significantly with Loper Bright Enterprises v. Raimondo.
In 2024, the Supreme Court overruled Chevron deference.
Courts must now independently interpret statutes rather than automatically deferring to an agency’s interpretation merely because the statute is ambiguous.
The Court emphasized that courts should independently interpret statutes while recognizing valid congressional delegations, fixing the boundaries of delegated authority, and ensuring reasoned decision-making within those boundaries.
This does not mean agencies no longer interpret statutes.
They necessarily interpret statutes when administering them.
But their interpretation does not automatically control simply because Congress has left statutory language ambiguous.
The distinction is fundamental:
Agencies administer statutes.
Courts ultimately determine the meaning of statutes when statutory interpretation is properly before them.
27. What Makes an Agency’s Action Unlawful?
An agency action can be unlawful for several different reasons.
No statutory authority
The agency lacks legal authority for the action.
Excessive delegation
The statutory structure raises constitutional concerns concerning delegated legislative power.
Procedural violation
The agency failed to follow required procedures.
Arbitrary or capricious action
The agency failed to engage in reasoned decision-making.
Constitutional violation
The agency infringed a constitutional right or violated constitutional structure.
Exceeding jurisdiction
The agency acted outside the subject matter or authority assigned to it.
Improper interpretation
The agency relied on a legal interpretation that a reviewing court determines is incorrect.
These categories demonstrate why agency authority must always be analyzed legally rather than simply practically.
28. Agency Authority Is Different From Agency Expertise
An agency may be the government’s leading expert on a particular subject.
That does not answer the question of whether the agency has authority to act.
Consider a hypothetical telecommunications agency.
The agency may have extraordinary technical expertise concerning emerging communication technologies.
But if Congress authorized it only to regulate spectrum allocation, that expertise does not automatically authorize it to regulate unrelated areas of internet commerce.
The distinction is:
Expertise answers:
What does the agency know?
Authority answers:
What is the agency legally allowed to do?
Administrative law is deeply concerned with the second question.
29. Agencies and the Public
Administrative agencies affect ordinary people in numerous ways.
A person may encounter an agency when:
- applying for a professional license;
- seeking a government benefit;
- operating a business;
- complying with environmental regulations;
- filing tax-related documents;
- responding to an investigation;
- challenging an administrative decision;
- applying for immigration benefits;
- dealing with workplace regulations; or
- contesting an administrative penalty.
Administrative law therefore affects far more than government lawyers.
It governs many everyday relationships between government and the public.
30. Agencies and Businesses
Businesses often interact with multiple administrative agencies.
A company may need to comply with rules concerning:
- employment;
- taxation;
- securities;
- environmental protection;
- consumer protection;
- workplace safety;
- transportation;
- data and communications;
- product safety; or
- financial reporting.
The administrative state therefore forms a significant part of the legal environment in which businesses operate.
For businesses, understanding agency authority can be just as important as understanding statutes enacted directly by Congress.
31. Agencies and Individual Rights
Administrative agencies can also affect fundamental interests.
Agency decisions may affect:
- property;
- employment;
- professional licenses;
- government benefits;
- immigration status;
- economic opportunities;
- privacy;
- reputation; and
- other legally protected interests.
This is why administrative law contains procedural safeguards.
Government efficiency is important.
But administrative efficiency does not automatically override constitutional rights.
Where protected interests are at stake, the Constitution and applicable statutes may require appropriate procedures.
32. The Difference Between an Agency and a Government Department
The terms agency, department, commission, bureau, and administration can sometimes be confusing.
They do not all have identical legal meanings.
A department may be a major executive organizational unit headed by a Cabinet-level official.
A bureau may be a subdivision within a department or agency.
A commission may refer to an agency structured as a multi-member body.
An administration may refer to a governmental organization created to administer a particular statutory program.
The precise legal structure depends on the statute establishing the institution.
For legal analysis, the important question is not simply what the organization is called.
It is:
What legal entity did Congress create, and what authority did Congress give it?
33. Agencies Are Not All Structured the Same Way
There is no single organizational model for administrative agencies.
Agencies may differ in:
- number of commissioners;
- appointment procedures;
- removal protections;
- relationship with the President;
- adjudicatory structure;
- rulemaking authority;
- enforcement powers;
- jurisdiction;
- funding;
- internal organization; and
- statutory mission.
This is why an administrative-law principle that applies to one agency may not automatically apply in exactly the same way to another.
Agency structure matters.
34. The Agency as a Legal Institution
An administrative agency should therefore be understood as more than an office.
It is a legal institution created or authorized by law to exercise specified governmental responsibilities.
Its legal identity determines:
- what it may regulate;
- whom it may regulate;
- which procedures it must follow;
- what remedies it may impose;
- who controls it;
- who may challenge its decisions; and
- which courts may review its actions.
This institutional perspective is essential for lawyers.
Before analyzing an agency’s decision, one must identify the agency itself.
35. A Practical Example
Imagine Congress passes a statute establishing a federal agency to regulate a dangerous industrial substance.
The statute gives the agency authority to:
- establish safety standards;
- inspect facilities;
- investigate violations;
- issue administrative penalties; and
- conduct certain administrative proceedings.
The agency then adopts a regulation requiring regulated companies to maintain particular safety records.
A company challenges the regulation.
The legal analysis might proceed as follows.
Step 1: Identify the agency
What agency issued the rule?
Step 2: Identify its organic statute
What statute created or authorized the agency?
Step 3: Identify delegated authority
Did Congress authorize rulemaking concerning safety records?
Step 4: Examine procedure
Did the agency follow the required rulemaking procedures?
Step 5: Examine substance
Does the regulation remain within the statutory purpose and authority?
Step 6: Consider constitutional questions
Does the agency’s exercise of power raise delegation, due process, or separation-of-powers concerns?
Step 7: Consider judicial review
What court or reviewing mechanism is available?
This example demonstrates why “the agency made a rule” is only the beginning of the legal analysis.
36. The Core Relationship
The relationship between Congress, agencies, and courts can be expressed simply:
Congress
creates the legal framework
↓
Administrative Agency
administers and implements the framework
↓
Regulated Parties and the Public
must comply with or interact with the administrative system
↓
Courts
review agency action when judicial review is available
This structure creates a system of delegated authority and legal accountability.
37. Why Administrative Agencies Matter
Administrative agencies are indispensable to modern government.
Without them, Congress would have to perform enormous amounts of technical administration itself.
Agencies allow government to:
- develop specialized expertise;
- administer complex programs;
- respond to technical developments;
- monitor regulated industries;
- enforce statutory requirements;
- provide public services;
- process large numbers of applications;
- conduct investigations; and
- develop detailed regulatory standards.
But the necessity of agencies does not make them legally unlimited.
Their legitimacy depends upon the principle that governmental power must have a lawful source and remain within lawful boundaries.
Frequently Asked Questions
What is an administrative agency?
An administrative agency is a governmental body authorized by law to administer statutes and governmental programs, often through rulemaking, enforcement, licensing, investigation, or adjudication. Cornell Wex: Administrative Agency
Who creates administrative agencies?
At the federal level, Congress generally creates agencies through statutes and establishes their powers, responsibilities, and organizational structures.
Where does an agency get its power?
An agency’s authority comes from the Constitution, statutes, valid delegations, and other applicable sources of law. Its organic statute is usually the starting point for determining its powers.
Are administrative agencies part of the executive branch?
Many are. Executive agencies operate within the executive branch. Independent agencies have different statutory structures and degrees of insulation from presidential control.
Are agencies a fourth branch of government?
No. The Constitution does not establish a fourth branch consisting of administrative agencies.
Can administrative agencies make regulations?
Yes. Agencies may issue regulations when Congress has lawfully delegated rulemaking authority to them.
Are agency regulations the same as statutes?
No. Statutes are enacted by Congress. Regulations are issued by agencies under delegated statutory authority.
Can agencies enforce the law?
Yes, when Congress has granted them enforcement authority. Enforcement may include investigations, inspections, administrative orders, penalties, and administrative proceedings.
Can agencies act like courts?
Agencies can conduct administrative adjudications when authorized by law. These proceedings can resemble judicial proceedings, but they operate within an administrative statutory framework.
Can agencies interpret statutes?
Yes. Agencies necessarily interpret statutes when administering them. But after Loper Bright, courts independently interpret statutes rather than automatically deferring to agency interpretations under Chevron.
Can an agency exceed its authority?
Yes. An agency that acts beyond the authority granted by law may be acting ultra vires and may be subject to judicial review.
What is the Administrative Procedure Act?
The APA is the principal federal statute establishing general procedures for federal administrative agencies, including important rules concerning rulemaking, adjudication, and judicial review.
Why do agencies need discretion?
Because Congress cannot predict every factual and technical circumstance that agencies will encounter. Discretion allows agencies to make lawful choices within delegated boundaries.
Who controls administrative agencies?
The answer depends on the agency. Congress controls agencies through statutes, appropriations, oversight, and other mechanisms. The President exercises significant control over executive agencies, while independent agencies may have greater statutory independence. Courts provide judicial review.

- The legitimacy of administrative government depends on the relationship between delegated power and legal limits.
Conclusion
An administrative agency is, at its core, an institution through which government carries law into practical operation.
Congress establishes statutory programs.
Agencies administer those programs.
They develop technical rules, investigate conduct, issue licenses, enforce legal requirements, conduct administrative proceedings, and perform countless other functions that modern government requires.
That makes agencies extraordinarily important.
But it also makes them extraordinarily important from a constitutional perspective.
An agency does not possess power simply because it is useful. It possesses power because the law gives it that power.
That distinction is the foundation of administrative law.
The central question is therefore not simply:
What does this agency do?
The more important legal question is:
What authority permits this agency to do it?
Once that question is answered, the rest of administrative law begins to make sense.
We can then examine the agency’s structure, its delegated powers, its procedures, its discretion, its regulations, its enforcement actions, and the mechanisms through which courts and other institutions hold it accountable.
Administrative agencies are therefore best understood not as unrestrained bureaucracies, but as legal institutions exercising delegated governmental power within a constitutional system.
And that brings us naturally to the next question: What kinds of administrative agencies exist, and how do their structures differ?
