Agency Guidance, Policy Statements, and Interpretive Rules

Agency Guidance, Policy Statements, and Interpretive Rules

Introduction

Administrative agencies do more than issue legally binding regulations.

They also publish guidance documents, interpretive rules, policy statements, manuals, circulars, advisory opinions, enforcement guidance, frequently asked questions, bulletins, and other materials explaining how the agency understands and administers the law.

These documents can be extremely important.

A company may rely on an agency’s guidance when deciding how to structure its operations.

A lawyer may consult an agency interpretation when advising a client.

A regulated entity may change its conduct because an agency has announced how it intends to interpret a regulation.

Yet there is a fundamental legal question:

When does agency guidance merely explain the law, and when does it actually become law?

That question lies at the heart of the distinction between legislative rules, interpretive rules, and general statements of policy.

The distinction matters because legislative rules ordinarily have the force and effect of law, while interpretive rules and policy statements generally do not.

The Administrative Procedure Act (APA) expressly exempts certain interpretive rules, general statements of policy, and rules concerning agency organization, procedure, or practice from the ordinary notice-and-comment requirements of § 553(b).

For a useful overview of these categories, the Cornell Law School Legal Information Institute’s explanation of administrative rules provides an especially useful starting point because it explains the distinction between legislative rules, interpretive rules, and policy statements.

The central problem can be expressed simply:

An agency may explain the law without necessarily making new law.

Understanding where that line lies is one of the most important skills in administrative law.

---

1. What Is Agency Guidance?

Agency guidance is information issued by an administrative agency to explain how the agency understands a statute, regulation, policy, procedure, or technical issue, or how the agency expects to exercise its authority.

Guidance can take many forms.

Examples include:

• guidance documents;
• interpretive memoranda;
• agency manuals;
• policy statements;
• enforcement policies;
• advisory opinions;
• circulars;
• bulletins;
• frequently asked questions;
• compliance guides;
• letters;
• interpretive statements;
• and other explanatory materials.

The term “guidance” is therefore extremely broad.

Not every document called guidance has the same legal significance.

One document might simply explain existing legal requirements.

Another might announce how an agency intends to exercise enforcement discretion.

Another might actually impose new requirements on regulated parties while being labeled “guidance.”

That last situation is where administrative-law problems can arise.

---

2. Why Do Agencies Issue Guidance?

Agencies operate in complex regulatory environments.

A statute may establish a broad legal requirement without answering every practical question.

An agency regulation may also leave room for interpretation.

Guidance allows an agency to explain how it understands those existing legal requirements.

For example, Congress might enact a statute prohibiting a particular form of discrimination.

An agency responsible for enforcing the statute might issue guidance explaining:

• what conduct it considers discriminatory;
• how complaints should be submitted;
• what evidence may be relevant;
• how investigations are conducted;
• and how existing regulations should be understood.

The guidance can make the regulatory system easier to understand without necessarily creating new legal obligations.

---

3. Guidance Versus Legislation

An administrative agency is not Congress.

Congress creates federal statutes.

Agencies administer and enforce statutes within the authority delegated to them.

That distinction matters.

Suppose Congress passes a statute requiring regulated companies to maintain certain safety standards.

An agency may issue guidance explaining how it interprets the statutory requirement.

But the agency cannot simply use a document labeled “guidance” to create entirely new statutory obligations that Congress never authorized.

This is one of the fundamental limits on administrative power.

The agency’s interpretation must remain connected to the authority granted by law.

---

4. Legislative Rules

To understand guidance, it is useful to begin with the category against which guidance is often compared: the legislative rule.

A legislative rule—also commonly called a substantive rule—is issued pursuant to delegated legislative authority and generally has the force and effect of law.

Such a rule can impose binding obligations on regulated parties.

For example, Congress might authorize an agency to establish emissions standards.

The agency may then promulgate a regulation establishing a legally binding emissions limit.

That regulation does more than explain what the law means.

It establishes a regulatory requirement that regulated parties must follow.

This is why legislative rules ordinarily fall within the APA’s notice-and-comment framework unless an exception applies.

---

5. Interpretive Rules

An interpretive rule is different.

An interpretive rule generally explains how an agency understands an existing statute or regulation.

It does not purport to create new legal obligations independently of the underlying law.

The Supreme Court emphasized this distinction in Perez v. Mortgage Bankers Association (2015).

Interpretive rules generally advise the public of the agency’s construction of the statutes and rules that the agency administers, rather than themselves having the force and effect of law.

The distinction can be expressed simply:

Legislative rule

“The law requires you to do X.”

Interpretive rule

“Here is how the agency understands the existing law that requires X.”

That difference can determine whether notice and comment is required.

---

6. Why Interpretive Rules Are Generally Exempt From Notice and Comment

Section 553(b)(A) of the APA generally exempts interpretive rules from the ordinary notice-and-comment requirements applicable to legislative rules.

The logic is straightforward.

If an agency is merely explaining an existing legal obligation, requiring the agency to go through full legislative rulemaking every time it explains the law could make administration unnecessarily cumbersome.

Suppose an agency regulation already requires a company to maintain certain records.

The agency publishes an interpretive document explaining what it believes the phrase “adequate records” means.

If that document merely explains the existing requirement, it may qualify as an interpretive rule rather than a legislative rule.

The agency may therefore be able to issue it without first conducting notice-and-comment rulemaking.

---

7. Interpretive Rules Cannot Create New Law

The exemption for interpretive rules has an important limit.

An agency cannot avoid notice and comment simply by calling a document “interpretive.”

If the document actually creates new binding requirements, the label may not save it.

Consider this example.

An existing regulation says:

“Covered employers must maintain appropriate safety records.”

The agency publishes guidance stating:

“For purposes of compliance, every covered employer must maintain a particular electronic record for exactly ten years.”

If the existing regulation does not contain such a requirement, the agency may face a serious question about whether the guidance is actually creating a new obligation.

The agency may call the document “guidance.”

But the legal question is:

What does the document actually do?

---

8. Labels Are Not Always Controlling

Administrative agencies frequently determine the titles of their own documents.

They may call something:

• guidance;
• policy;
• interpretation;
• memorandum;
• bulletin;
• directive;
• advisory;
• or enforcement policy.

But the title does not necessarily determine the legal character of the document.

Courts may examine factors such as:

• the source of authority;
• the language used;
• the substance of the document;
• whether it imposes new obligations;
• whether the agency treats it as binding;
• whether regulated parties are free to disregard it;
• how the agency adopted it;
• and the practical consequences of the document.

This reflects an important principle of administrative law:

Substance matters more than labels.

Cornell’s Wex likewise notes that an agency’s label is not controlling and that courts may examine the document’s authority, content, adoption process, and whether it purports to bind the public or the agency.

---

9. General Statements of Policy

A general statement of policy is another important category.

A policy statement generally announces how an agency intends to exercise its discretion.

For example, an agency might announce:

“In ordinary circumstances, the agency intends to prioritize enforcement against violations presenting an immediate risk to public safety.”

That statement does not necessarily create a new legal obligation.

Instead, it tells the public how the agency intends to use its existing enforcement discretion.

Policy statements therefore answer a different question from interpretive rules.

Interpretive rule

“This is what we think the existing law means.”

Policy statement

“This is how we generally intend to exercise our discretion.”

The distinction is subtle but legally significant.

---

10. Why Policy Statements Are Different

Agencies have discretion.

They must decide how to allocate enforcement resources, establish priorities, and administer programs.

A policy statement can provide transparency concerning those choices.

For example, an agency might announce that it intends to focus enforcement resources on:

• serious violations;
• repeat offenders;
• conduct causing substantial public harm;
• or industries presenting particular risks.

The policy statement helps regulated parties understand the agency’s priorities.

But it does not necessarily mean that the agency has created a legally binding requirement.

---

11. Policy Statements Generally Do Not Bind the Public

A genuine policy statement normally does not impose a new legal obligation on private parties.

Nor does it ordinarily eliminate the agency’s ability to exercise discretion differently when circumstances justify it.

Imagine that an agency says:

“The agency generally intends to issue warnings before imposing civil penalties for first-time minor violations.”

That statement communicates agency policy.

But it does not necessarily give every regulated party a legal right to receive a warning.

The distinction between a policy and a binding legal requirement is crucial.

---

12. Guidance Can Be Extremely Powerful Without Being Legally Binding

This creates one of the most interesting features of administrative law.

A document can lack the force of law and still have enormous practical influence.

Imagine that an agency publishes a compliance manual explaining how inspectors evaluate workplace safety.

The manual may technically be nonbinding.

But businesses may still follow it because they know that agency inspectors use it.

Similarly, an agency’s enforcement guidance may influence how lawyers advise clients.

Hospitals, banks, manufacturers, employers, and other regulated entities may voluntarily follow guidance because doing so reduces regulatory uncertainty.

This creates a distinction between:

legal force

and

practical force.

A document may have little formal legal force while possessing considerable practical influence.

---

13. The Problem of “Binding in Practice”

This distinction creates a recurring administrative-law problem.

Suppose an agency says:

“This guidance is nonbinding.”

But agency officials then tell regulated parties:

“You must follow this guidance or we will take enforcement action.”

The document may now look much less like a genuinely voluntary interpretation.

The question becomes whether the agency is effectively using guidance as a substitute for a legislative rule.

That can create concerns about procedural fairness and the avoidance of notice-and-comment requirements.

The agency cannot necessarily do indirectly what it is required to do directly.

---

14. Perez v. Mortgage Bankers Association

The Supreme Court’s decision in Perez v. Mortgage Bankers Association is an important case in this area.

The case involved an agency interpretation concerning overtime compensation.

The Supreme Court held that an agency does not generally have to use notice-and-comment procedures merely because it changes an interpretive rule.

The Court relied on the APA’s express exemption for interpretive rules.

The significance of the case is broader than the particular dispute.

It confirms that the APA distinguishes between:

• legislative rules, which generally require notice and comment; and
• interpretive rules, which ordinarily do not.

But this distinction depends on the document genuinely remaining interpretive.

---

15. Kisor v. Wilkie and Interpretive Rules

The Supreme Court also addressed interpretive rules in Kisor v. Wilkie (2019).

The Court emphasized an important characteristic of interpretive rules:

They do not themselves have the force and effect of law.

Instead, they explain how an agency understands the binding law that it administers.

This matters because an agency should not be able to transform an interpretation into a binding legal requirement merely by placing it in a guidance document.

The distinction between interpretation and legislation therefore remains fundamental.

---

16. Interpretive Rules and Agency Regulations

Interpretive rules frequently arise when agencies administer their own regulations.

Suppose an agency has promulgated a regulation stating:

“Covered facilities must maintain adequate safeguards.”

Later, the agency publishes an interpretation explaining what it considers an “adequate safeguard.”

That document may be interpretive.

The agency is attempting to explain the meaning of language already contained in the regulation.

But suppose the agency instead announces:

“All covered facilities must now install a particular security system.”

If the existing regulation does not require that system, the agency may be doing more than interpreting.

It may be creating a substantive requirement.

The difference can be decisive.

---

17. Guidance Documents

The modern administrative state relies heavily on guidance documents.

Guidance may explain:

• how to comply with regulations;
• how to submit applications;
• how the agency interprets technical requirements;
• how enforcement priorities operate;
• how the agency evaluates risk;
• how regulated parties can avoid violations;
• or how an existing legal standard applies to common situations.

Guidance can therefore make complicated regulatory systems more understandable.

Without guidance, regulated parties might face uncertainty about how agencies actually administer complex statutes and regulations.

---

18. Guidance Can Reduce Regulatory Uncertainty

Imagine a regulation containing a general requirement:

“The regulated entity must take reasonable measures to protect customer information.”

That language may leave many practical questions unanswered.

What security measures are reasonable?

How often should systems be tested?

What documentation should be maintained?

What procedures should employees follow?

Agency guidance can provide practical answers.

Even if the guidance is not itself legally binding, it can make the regulatory environment more predictable.

This can be especially valuable in technically complex industries.

---

19. Guidance Can Also Create Regulatory Risk

The same feature that makes guidance useful can make it dangerous.

If regulated parties believe they must follow guidance even though the agency did not promulgate it through required procedures, the guidance can effectively become a substitute for regulation.

That can undermine:

• public participation;
• transparency;
• procedural safeguards;
• separation of powers;
• and judicial review.

The problem is not that agencies issue guidance.

The problem arises when guidance becomes a hidden source of binding legal obligations.

---

20. The Difference Between “May” and “Must”

One practical way to identify the nature of a document is to examine its language.

Consider:

“The agency recommends that regulated entities maintain electronic records.”

That sounds like guidance.

Now consider:

“Regulated entities must maintain electronic records.”

That sounds substantially more binding.

But even this linguistic distinction is not conclusive.

An agency may use soft language while treating the guidance as mandatory.

Conversely, an agency may use strong language to describe what it believes existing law already requires.

Therefore, the entire document and its legal context must be considered.

---

21. Enforcement Guidance

Agencies often issue guidance concerning enforcement.

For example, an agency may explain:

• which violations are enforcement priorities;
• when warnings are generally appropriate;
• when civil penalties are likely;
• how aggravating or mitigating factors are considered;
• or which circumstances may justify leniency.

Such guidance can help regulated parties understand enforcement priorities.

But enforcement guidance ordinarily should not create a new substantive legal requirement that does not already exist in statute or regulation.

Otherwise, the agency risks transforming enforcement policy into an unofficial regulatory code.

---

22. Advisory Opinions and Interpretive Letters

Agencies may also issue interpretations in response to specific questions.

For example, a regulated company may ask an agency:

“Does this existing regulation apply to our particular product?”

The agency may respond with an interpretive letter.

Such a letter can be extremely valuable to the recipient.

But its legal status depends on the governing statute, the agency’s authority, the nature of the interpretation, and the circumstances in which it was issued.

An agency letter is not automatically equivalent to a legislative rule.

---

23. Guidance and Due Process

Agency guidance can also raise questions of fairness.

Suppose the government penalizes a company for violating a requirement that appears nowhere in a statute or properly promulgated regulation but appears only in an agency guidance document.

The company may argue that it lacked legally adequate notice of the supposed obligation.

This can raise serious due-process concerns.

People should ordinarily be able to determine what the law requires before being subjected to legal penalties for violating it.

The principle is especially important where the government seeks to impose serious sanctions.

---

24. Guidance and Fair Notice

Fair notice is closely related to the rule of law.

A legal system becomes problematic if government officials can punish people based on requirements that were never properly established or adequately communicated.

Imagine receiving a penalty for violating a rule that exists only in an internal agency manual that was never lawfully promulgated as a binding regulation.

The obvious question would be:

Where did this legal obligation come from?

Administrative law therefore distinguishes between explaining existing law and creating new law.

Guidance can clarify.

It cannot automatically legislate.

---

25. Judicial Review of Guidance

Agency guidance can sometimes be challenged in court.

But whether a particular guidance document is reviewable depends on several factors, including:

• whether the agency action is final;
• whether it has legal consequences;
• whether the plaintiff has standing;
• whether the dispute is ripe;
• whether review is barred by another doctrine;
• and whether the document is genuinely nonbinding.

The fact that a document is called guidance does not automatically make it immune from judicial scrutiny.

Nor does the fact that an agency has issued guidance automatically create a judicially reviewable controversy.

These questions belong to the broader law of judicial review.

---

26. Guidance and the Administrative Record

Guidance can also become relevant to litigation concerning later agency action.

Suppose an agency uses guidance to explain how it intends to enforce a regulation.

Later, the agency brings an enforcement action.

The regulated party may argue that the agency is applying the guidance as if it were binding law.

The guidance may then become relevant to determining what the agency believed the law required and how it exercised its discretion.

Thus, even a nonbinding document can become important evidence in administrative litigation.

---

27. Loper Bright and Agency Interpretations

The modern law of agency interpretation must also be understood in light of Loper Bright Enterprises v. Raimondo (2024).

Before Loper Bright, Chevron doctrine sometimes required courts to defer to reasonable agency interpretations of ambiguous statutes.

The Supreme Court overruled Chevron.

Courts now must exercise their own independent judgment in interpreting statutes rather than automatically deferring to an agency simply because the statute is ambiguous. Cornell’s current Wex treatment of administrative law reflects this post-Loper Bright framework.

This does not make agency interpretations irrelevant.

Agency interpretations may still be persuasive.

An agency may possess expertise and may have developed a considered position through a careful administrative process.

But an agency’s guidance does not become legally authoritative simply because the agency issued it.

---

28. Skidmore and Persuasive Agency Interpretations

Although Chevron has been overruled, agency interpretations can still receive consideration based on their persuasive value.

The classic framework comes from Skidmore v. Swift & Co.

Under Skidmore, the weight given to an agency interpretation depends on considerations such as:

• the thoroughness of the agency’s reasoning;
• the validity of its reasoning;
• consistency with earlier and later interpretations;
• and the agency’s specialized experience.

The key idea is persuasion rather than automatic binding authority.

An agency may be persuasive without being legally controlling.

---

29. Agency Guidance and Separation of Powers

The distinction between guidance and binding rules also has constitutional significance.

Congress makes federal law.

Agencies administer statutes within delegated authority.

Courts interpret law and review government action.

If an agency could create binding legal obligations simply by publishing a guidance document, it could potentially exercise legislative power without following the procedures designed to constrain that power.

That is why the distinction between:

interpreting law

and

making law

is so important.

The categories are not always perfectly clear, but the constitutional structure makes the distinction unavoidable.

---

30. The Major Practical Question: Can the Agency Enforce It?

One useful question when analyzing guidance is:

Can the agency lawfully impose a penalty solely because someone failed to follow this document?

If the answer is clearly yes, the document may be functioning more like a binding legislative rule.

If the document merely explains existing law and the agency must rely on the underlying statute or regulation to establish the violation, it is more likely to be genuinely interpretive or advisory.

This is not the only question courts consider.

But it is an excellent starting point.

---

31. A Practical Comparison

Feature	Legislative Rule	Interpretive Rule	Policy Statement
Primary purpose	Creates binding regulatory requirements	Explains existing law	Announces agency policy or enforcement approach
Force of law	Generally yes	Generally no	Generally no
Ordinary notice and comment	Generally required	Generally exempt under § 553(b)(A)	Generally exempt under § 553(b)(A)
Creates new obligations?	Yes, within delegated authority	No	No
Explains existing law?	May, but also establishes requirements	Yes	Sometimes
Announces enforcement priorities?	Not necessarily	Not usually	Often
Agency discretion	Often limited by rule	Usually does not itself eliminate discretion	Central feature
Judicial significance	Binding subject to review	Potentially persuasive	Potentially persuasive
Label controls?	No	No	No

The table provides a useful starting point, but actual classification can be much more complicated.

---

32. Why the Classification Matters

The classification matters because procedural requirements depend on the legal character of the agency action.

If an agency is creating a legislative rule, notice and comment may be required.

If the agency is genuinely interpreting existing law, the APA generally permits it to issue an interpretive rule without ordinary notice and comment.

If the agency is merely announcing a policy, it may likewise be exempt.

But if an agency disguises a legislative rule as guidance, the exemption may not apply.

Thus:

Classification determines procedure, and procedure can determine validity.

---

33. A Hypothetical Example

Imagine Congress passes a statute requiring financial institutions to protect customer information.

A federal agency adopts a regulation requiring institutions to maintain “reasonable security measures.”

The agency then publishes guidance explaining that it considers the following practices useful:

• encryption;
• employee training;
• access controls;
• periodic security testing;
• incident-response procedures.

That is likely to function as guidance if the agency is explaining what it considers reasonable security measures.

But suppose the agency later announces:

“Any institution that fails to use our specific software platform will be deemed in violation.”

If the existing statute and regulation never required that software, the agency may have moved beyond interpretation.

It may be attempting to create a new substantive requirement.

The title of the document would not resolve the issue.

---

34. Another Example: Enforcement Priorities

Suppose an agency has authority to impose civil penalties for violations.

The agency publishes a policy stating:

“For minor first-time violations that do not threaten public safety, the agency generally intends to issue a warning before imposing a penalty.”

This is likely a policy statement.

It describes how the agency intends to exercise discretion.

Now suppose the agency publishes:

“Any company that violates this regulation must receive a warning before the agency may impose a penalty.”

That statement sounds more like a legal rule.

The agency may be attempting to establish a binding procedural limitation rather than merely announcing discretionary policy.

Again, substance matters.

---

35. Agency Guidance and Regulated Parties

For regulated parties, the practical lesson is important.

Do not assume that every agency publication is:

• binding law;
• meaningless advice;
• or something in between.

Instead, ask:

1. What is the source of legal authority?
2. What underlying statute or regulation is being interpreted?
3. Does the document claim to create new obligations?
4. Is compliance described as mandatory?
5. Can the agency impose a penalty solely for violating the document?
6. Was notice and comment used?
7. Does the agency itself treat the document as binding?
8. What happens if a regulated party disagrees with it?
9. Is the document genuinely interpretive or merely labeled that way?

These questions can reveal the document’s actual legal significance.

---

36. Agency Guidance and Lawyers

Lawyers practicing administrative law must become comfortable reading agency guidance critically.

A lawyer should not automatically tell a client:

“The agency says this, so this is the law.”

The better question is:

What is the legal source of the requirement?

The answer might be:

• a statute;
• a legislative regulation;
• an adjudicatory decision;
• an interpretive rule;
• a policy statement;
• or merely agency preference.

These sources can have very different legal consequences.

---

37. The Difference Between “Law” and “How the Government Sees the Law”

This distinction can be summarized in a simple conceptual formula.

Legislative rule

Law → agency authority → binding regulation

Interpretive rule

Existing law → agency interpretation → explanation

Policy statement

Existing authority → agency discretion → announced policy

The categories overlap in practice, but the conceptual distinction is valuable.

An interpretive rule says:

“This is how we understand the law.”

A policy statement says:

“This is how we intend to exercise our discretion.”

A legislative rule says:

“This is a binding requirement adopted pursuant to delegated authority.”

---

38. The Rule of Law Dimension

The distinction between guidance and binding rules ultimately reflects the rule of law.

Government officials should not be able to create binding obligations through informal documents whenever convenient.

Legal obligations should arise from recognized sources of legal authority.

This principle protects:

• predictability;
• transparency;
• fair notice;
• accountability;
• separation of powers;
• and meaningful judicial review.

At the same time, government needs flexibility to explain and administer complex laws.

Administrative law therefore attempts to preserve both principles:

Agencies need room to interpret and administer law.

But:

Agencies cannot simply transform interpretation into legislation without lawful authority and procedure.

That tension is at the heart of modern administrative law.

---

39. A Lawyer’s Checklist

When reviewing agency guidance, ask:

Authority

1. What statute authorizes the agency’s action?
2. What regulation or statute is being interpreted?

Character

3. Is the document legislative, interpretive, or policy-oriented?
4. Does it create new legal obligations?
5. Does it merely explain existing requirements?
6. Does it announce how the agency intends to exercise discretion?

Procedure

7. Was notice and comment used?
8. If not, what exemption does the agency rely upon?
9. Is the exemption legally appropriate?

Effect

10. Does the agency treat the document as binding?
11. Can a regulated party be penalized for violating it?
12. Is the agency effectively enforcing it as law?

Judicial review

13. Is the document final agency action?
14. Is there a concrete legal injury?
15. Is judicial review available?
16. How persuasive is the agency’s interpretation after Loper Bright?

These questions provide a practical framework for determining whether an agency document is genuinely guidance or something more legally significant.

---

40. Frequently Asked Questions

What is agency guidance?

Agency guidance is information issued by an administrative agency explaining how the agency understands or intends to administer existing law, regulations, policies, or technical requirements.

What is an interpretive rule?

An interpretive rule generally explains an agency’s understanding of an existing statute or regulation rather than independently creating new legal obligations.

What is a policy statement?

A policy statement generally announces how an agency intends to exercise discretion or prioritize its enforcement and administrative activities.

Do interpretive rules have the force of law?

Generally, no. Interpretive rules ordinarily explain existing law rather than independently creating binding legal obligations.

Do policy statements have the force of law?

Generally, no. A genuine policy statement normally announces agency policy without creating new binding obligations for the public.

Do interpretive rules require notice and comment?

Generally, no. Section 553(b)(A) exempts interpretive rules from ordinary notice-and-comment requirements, subject to other applicable legal requirements.

Can an agency call a legislative rule “guidance”?

An agency’s label is not necessarily controlling. Courts may examine the substance and practical effect of the document.

Can guidance be legally important even if it is not binding?

Yes. Guidance can have substantial practical influence and can become relevant in later administrative or judicial proceedings.

Can an agency enforce guidance?

An agency generally cannot use genuinely nonbinding guidance as though it were an independently binding legislative rule. The agency ordinarily must rely on an underlying source of legal authority for an enforceable obligation.

Does Loper Bright make agency interpretations irrelevant?

No. Loper Bright eliminated Chevron’s mandatory deference framework, but agency interpretations may still be considered for their persuasive value depending on the circumstances.

Why does the distinction matter?

Because legislative rules generally must follow notice-and-comment procedures, while genuine interpretive rules and policy statements generally fall within § 553(b)(A)’s exemptions.

---

Conclusion

Agency guidance, policy statements, and interpretive rules occupy an unusual position in administrative law.

They are not necessarily laws in the same sense as statutes or legislative regulations.

But they can have enormous practical importance.

They tell regulated parties how agencies understand complicated statutes and regulations.

They reveal enforcement priorities.

They can make regulatory systems more predictable.

They can help agencies administer complex programs consistently.

At the same time, guidance creates a potential danger.

An agency might be tempted to use an apparently nonbinding document to impose requirements that should instead be established through legally authorized rulemaking.

That is why the distinction between interpretation and legislation matters so much.

A genuine interpretive rule says:

“This is how we understand the law that already exists.”

A genuine policy statement says:

“This is how we generally intend to exercise our discretion.”

A legislative rule says:

“This is a binding requirement adopted pursuant to delegated authority.”

The three categories may sometimes be difficult to distinguish.

But the underlying principle is clear.

Administrative agencies possess substantial governmental power, but that power must remain connected to lawful authority and lawful procedure.

Guidance can explain the law.

Policy can announce administrative priorities.

Interpretation can clarify existing requirements.

But none of these labels gives an agency unlimited power to make new law without the authority and procedures that the legal system requires.

That boundary is essential to the rule of law.
