Deference to Administrative Agencies

Deference to Administrative Agencies

Introduction

Deference to administrative agencies refers to the degree of respect or weight that courts give to an agency’s decisions when reviewing them.

For much of modern administrative-law history, deference was closely associated with the idea that agencies possess specialized expertise and that courts should sometimes accept reasonable agency interpretations of statutes or regulations. But the law of administrative deference has changed significantly over time.

The most important recent development is the Supreme Court’s 2024 decision in Loper Bright Enterprises v. Raimondo. The Court overruled Chevron deference, rejecting the rule that courts should defer to an agency’s reasonable interpretation of an ambiguous statute simply because the agency administers that statute. Under Loper Bright, courts must independently determine the meaning of federal statutes.

That does not, however, mean that administrative agencies receive no judicial respect.

Courts may still consider agency expertise, reasoning, consistency, experience, factual findings, and policy judgments. Agencies may also receive substantial judicial deference in areas where Congress has lawfully delegated discretion or where the applicable standard of review requires deference to factual or policy judgments.

The modern principle is therefore more nuanced:

Courts do not automatically defer to agencies on questions of statutory meaning, but agencies may still receive appropriate judicial respect within the authority Congress has lawfully delegated to them.

Understanding that distinction is essential to understanding modern administrative law.

What Is Administrative Deference?

Administrative deference describes the situation in which a reviewing court gives an agency’s decision some degree of judicial respect rather than reconsidering the matter entirely from the beginning.

The amount of deference depends on what the agency did and what question the court is being asked to decide.

For example, an agency may:

• interpret a federal statute;
• interpret one of its own regulations;
• determine disputed facts;
• evaluate scientific or technical evidence;
• choose among several lawful regulatory options;
• impose an administrative penalty;
• issue a rule;
• adjudicate a dispute; or
• exercise discretion granted by Congress.

These different activities do not necessarily receive the same treatment.

This is why it is misleading to say simply that “courts defer to agencies.”

The more precise question is:

Deference to the agency about what?

---

Why Do Courts Give Agencies Any Deference?

The traditional justification for administrative deference is largely institutional.

Administrative agencies often possess expertise that courts do not.

An agency may employ:

• scientists;
• economists;
• engineers;
• physicians;
• financial specialists;
• environmental experts;
• statisticians;
• investigators; and
• other technical professionals.

Agencies may also spend years administering a particular regulatory program.

A federal environmental agency, for example, may have extensive experience evaluating pollution data. A financial regulator may possess specialized knowledge of securities markets. A communications agency may understand highly technical aspects of telecommunications infrastructure.

A court deciding a legal dispute does not necessarily possess the same institutional knowledge.

Deference can therefore recognize the legitimate role of agencies without allowing agencies to become the final authority on every legal question.

---

Deference Does Not Mean Judicial Abdication

One of the most important principles in administrative law is that deference does not mean surrender of judicial authority.

Courts remain responsible for determining whether government action is lawful.

An agency cannot acquire unlimited authority merely because it has technical expertise.

The Supreme Court’s decision in Loper Bright emphasized this distinction. When a statute delegates discretionary authority to an agency, the reviewing court must independently interpret the statute, identify the boundaries of the delegated authority, and determine whether the agency engaged in reasoned decision-making within those boundaries.

Thus:

Agency expertise may justify judicial respect.

But:

Agency expertise does not automatically determine the meaning of the law.

---

The Historical Development of Agency Deference

The doctrine of administrative deference has developed through several different stages.

There was no single, uninterrupted rule under which courts always deferred to agencies.

Instead, the Supreme Court’s approach has changed over time.

Several doctrines are particularly important:

1. early judicial respect for agency expertise;
2. Skidmore persuasive weight;
3. Chevron statutory deference;
4. Auer and Kisor deference concerning agency regulations; and
5. the modern post-Loper Bright framework.

Understanding these doctrines historically helps explain why “administrative deference” cannot be reduced to one rule.

---

Skidmore Deference

One of the most important early cases is Skidmore v. Swift & Co., 323 U.S. 134 (1944).

The case concerned an interpretation offered by the federal agency responsible for administering the relevant labor statute.

The Supreme Court did not establish a rule requiring courts to accept the agency’s interpretation.

Instead, the Court recognized that an agency’s views could be persuasive depending upon factors such as:

• the thoroughness of the agency’s consideration;
• the validity of its reasoning;
• the consistency of its interpretation;
• its specialized experience; and
• other factors giving the interpretation power to persuade.

This type of judicial respect is often described as Skidmore deference, although “Skidmore respect” may sometimes be a more accurate description.

The critical point is that the court retains independent judgment.

The agency’s interpretation may be persuasive without being controlling.

---

What Made Skidmore Different?

The difference can be stated simply.

Under a persuasive-weight approach:

“The agency has a good argument, and its expertise may make that argument especially persuasive.”

Under a binding-deference approach:

“The agency’s reasonable interpretation must be accepted even if the court would have chosen another reasonable interpretation.”

That distinction became central to the later development of Chevron.

---

Chevron Deference

In 1984, the Supreme Court decided Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.

For approximately four decades, Chevron became one of the most influential doctrines in administrative law.

Under the traditional Chevron framework, courts generally asked:

1. Did Congress clearly resolve the statutory question?
2. If Congress had not clearly resolved the question, was the agency’s interpretation reasonable?

If the statute was ambiguous and the agency’s interpretation was reasonable, courts generally deferred to the agency’s interpretation.

Cornell’s Legal Information Institute describes Chevron as the historical doctrine under which courts deferred to reasonable agency interpretations of ambiguous statutes.

Chevron therefore represented a significantly stronger form of deference than Skidmore.

The agency’s interpretation could become controlling even when the court itself would have preferred another reasonable interpretation.

---

Why Chevron Was Controversial

Chevron generated extensive debate because it raised difficult questions about the constitutional structure of government.

Critics argued that allowing agencies to resolve statutory ambiguity could give executive-branch officials excessive authority to determine the meaning of laws enacted by Congress.

Supporters argued that Congress frequently delegates policymaking authority to agencies and that agencies possess technical expertise and political accountability that courts lack.

The debate therefore involved more than administrative efficiency.

It implicated:

• separation of powers;
• judicial authority;
• congressional delegation;
• executive power;
• agency expertise; and
• the proper role of courts in statutory interpretation.

These issues eventually became central to Loper Bright.

---

Loper Bright and the End of Chevron Deference

In 2024, the Supreme Court decided Loper Bright Enterprises v. Raimondo.

The Court overruled Chevron.

The Court held that the Administrative Procedure Act requires courts to exercise independent judgment when deciding questions of statutory meaning. The APA directs reviewing courts to “decide all relevant questions of law” and interpret statutory provisions.

The Court rejected the idea that statutory ambiguity automatically represents an implicit delegation of interpretive authority to an administrative agency.

In other words:

An unclear statute does not automatically mean that Congress intended the agency to decide what the statute means.

The court must still determine the statute’s best interpretation using the ordinary tools of statutory interpretation.

Cornell’s current explanation of administrative law likewise identifies Loper Bright as the decision that overturned Chevron and states that courts must independently interpret statutes rather than automatically defer to agency interpretations.

---

What Loper Bright Changed

After Loper Bright, a federal court reviewing an agency’s interpretation of a statute generally does not ask:

“Is the agency’s interpretation reasonable?”

Instead, the court asks:

“What is the best interpretation of the statute?”

The agency’s interpretation may still be considered.

But the agency does not win merely because its interpretation is reasonable.

The distinction is fundamental.

Before Loper Bright

A court could encounter two reasonable interpretations:

• Interpretation A — the court’s preferred interpretation
• Interpretation B — the agency’s reasonable interpretation

Under Chevron, the agency could prevail if the statute was ambiguous and the agency’s interpretation was reasonable.

After Loper Bright

The court must independently determine the statute’s meaning.

If Interpretation A is the better reading, the court applies Interpretation A even if the agency prefers Interpretation B.

The agency cannot obtain controlling authority merely by identifying statutory ambiguity.

---

Does Loper Bright Eliminate All Administrative Deference?

No.

This is perhaps the most important point in this entire article.

Loper Bright ended Chevron deference, not every form of judicial respect for agencies.

The Supreme Court expressly recognized that courts may still consider agency interpretations as an aid to statutory interpretation.

The Court noted that courts may seek assistance from the views of those responsible for implementing particular statutes, including under the principle reflected in Skidmore.

Agencies may also retain substantial room for discretion where Congress actually delegated discretionary authority.

And courts may continue to apply deferential standards to agency policymaking and factfinding where the APA or other governing law calls for those standards.

Therefore, the modern framework is not:

“Courts never defer.”

It is:

“Courts do not automatically surrender independent legal judgment to agencies.”

---

Agency Expertise Still Matters

Agency expertise remains relevant after Loper Bright.

Suppose an agency has spent twenty years administering a highly technical statute.

The agency has:

• extensive institutional experience;
• technical knowledge;
• a long record of applying the statute;
• specialized understanding of the regulated industry; and
• a carefully reasoned interpretation.

A court may find the agency’s interpretation persuasive.

But the court does not have to accept it simply because the agency possesses expertise.

This distinction allows courts to benefit from administrative expertise without transferring ultimate interpretive authority from the judiciary to the agency.

---

Deference to Agency Factfinding

Statutory interpretation is not the only thing agencies do.

Agencies also make factual findings.

For example, an agency might determine:

• whether a violation occurred;
• whether a scientific study supports a regulatory conclusion;
• whether a person satisfies statutory eligibility requirements;
• whether a regulated company complied with a particular requirement; or
• whether evidence establishes a particular factual circumstance.

These factual determinations can receive substantial judicial deference under the applicable standard of review.

The important distinction is:

Loper Bright concerns the judicial interpretation of law.

It does not transform every agency factual determination into a completely new judicial proceeding.

The Supreme Court itself emphasized that the APA prescribes deferential judicial review for agency policymaking and factfinding while requiring independent judicial judgment on questions of law.

---

Deference to Agency Policymaking

Agencies may also make policy choices within the authority Congress has lawfully delegated.

Suppose Congress directs an agency to establish environmental standards that adequately protect public health while considering economic feasibility.

Congress may have given the agency a range of lawful choices.

The agency could choose one permissible regulatory level.

A reviewing court ordinarily does not replace that decision merely because the judge personally prefers another policy.

Instead, the court may ask whether the agency:

• acted within statutory authority;
• considered relevant factors;
• relied on appropriate evidence;
• considered important alternatives;
• explained its reasoning; and
• reached a decision that satisfies the applicable standard of review.

This is often described as reasoned decision-making.

The Supreme Court’s Loper Bright opinion specifically recognized that where Congress has delegated discretionary authority, courts must identify the boundaries of that delegation and ensure that the agency has engaged in reasoned decision-making within those boundaries.

---

Agency Interpretations of Their Own Regulations

A different question arises when an agency interprets its own regulation rather than a statute.

Historically, this area was associated with Auer or Seminole Rock deference.

Under that doctrine, courts sometimes deferred to an agency’s reasonable interpretation of an ambiguous regulation administered by that agency.

The Supreme Court substantially limited this doctrine in Kisor v. Wilkie, 588 U.S. 558 (2019).

Kisor did not simply authorize agencies to interpret their regulations however they wished.

Instead, it imposed significant conditions before deference could be given.

Among other things, courts must first determine that the regulation is genuinely ambiguous after exhausting traditional interpretive tools. The agency’s interpretation must also reflect the agency’s authoritative and considered judgment and must represent its fair and considered position rather than a convenient litigation position.

This is different from Chevron’s former approach to statutory ambiguity.

The distinction matters because:

Interpreting a statute and interpreting an agency’s own regulation are not identical legal problems.

---

Why Agency Self-Interpretation Raises Special Concerns

Allowing an agency to interpret its own regulation creates a potential conflict.

The agency may have:

1. written the regulation;
2. interpreted the regulation;
3. enforced the regulation; and
4. defended its interpretation in court.

That combination can raise concerns about excessive administrative power.

For this reason, judicial deference to an agency’s interpretation of its own regulation has been constrained.

The Supreme Court’s treatment of Auer deference in Kisor illustrates the broader principle that deference must remain compatible with the judiciary’s role and with the limits imposed by law.

---

Deference and Agency Guidance

Agencies frequently issue materials that do not have the force of law.

Examples include:

• guidance documents;
• policy statements;
• advisory opinions;
• manuals;
• interpretive letters;
• enforcement guidance; and
• informal explanations.

These materials may help regulated parties understand how an agency views a statute or regulation.

But an agency generally cannot transform guidance into binding law merely by labeling it “guidance.”

The legal significance of an agency interpretation therefore depends partly on:

• the source of the agency’s authority;
• the form in which the interpretation was issued;
• whether required procedures were followed;
• whether Congress delegated relevant authority; and
• whether the agency claims the interpretation has binding legal effect.

An agency’s informal statement may be persuasive without possessing the force of law.

---

Deference and Agency Rulemaking

Agency rulemaking provides another important example.

Suppose Congress authorizes an agency to regulate a particular subject and leaves the agency discretion to determine technical standards.

The agency may adopt a rule after notice-and-comment rulemaking.

If challenged, the court may independently determine whether Congress authorized the agency to regulate in the relevant manner.

But once the court determines that the agency possesses lawful authority, the agency’s policy choice may be reviewed under the applicable standard for agency action.

The court may ask whether the agency:

• considered relevant evidence;
• explained its reasoning;
• responded to significant objections;
• considered reasonable alternatives;
• complied with statutory requirements; and
• avoided arbitrary or capricious decision-making.

Thus, judicial independence over legal authority can coexist with judicial restraint concerning lawful policy choices.

---

Deference and the Administrative Record

The administrative record is particularly important when evaluating agency reasoning.

A court cannot meaningfully determine whether an agency acted reasonably without examining the materials on which the agency based its decision.

The record may reveal:

• what evidence the agency considered;
• what alternatives it evaluated;
• what assumptions it made;
• what statutory factors it relied upon;
• whether it addressed contrary evidence; and
• how it reached its final conclusion.

This is why judicial deference does not mean that courts simply accept agency decisions without examination.

A deferential standard still requires judicial review.

---

Deference and the Arbitrary-and-Capricious Standard

The arbitrary-and-capricious standard illustrates how agency deference operates after Loper Bright.

The court independently determines the law.

But when reviewing an agency’s policy decision, the court may ask whether the agency engaged in reasoned decision-making.

The court generally does not ask:

“Would I have adopted this policy?”

Instead, it asks:

“Did the agency act within its lawful authority and reasonably explain why it adopted this policy?”

This distinction preserves agency discretion while preventing agencies from acting without rational explanation.

---

Deference Does Not Protect Unlawful Agency Action

An agency cannot invoke expertise to escape statutory limits.

For example, suppose Congress authorizes an agency to regulate commercial fishing but says nothing about regulating an unrelated industry.

The agency cannot respond:

“We have expertise in environmental regulation, therefore we can regulate anything affecting the environment.”

Expertise does not create statutory authority.

The court must determine whether Congress actually delegated the relevant power.

This principle became especially significant after Loper Bright, which emphasized the judicial responsibility to identify the boundaries of delegated authority.

---

Deference and Separation of Powers

The debate over administrative deference is fundamentally connected to separation of powers.

Three institutions are particularly important.

Congress

Congress creates agencies and establishes their statutory authority.

Executive agencies

Agencies administer and enforce the laws within the authority Congress has provided.

Courts

Courts determine whether governmental action is lawful.

Deference must therefore be understood within this constitutional structure.

Too little respect for agency expertise can result in courts improperly taking over administrative policymaking.

Too much deference can allow agencies to determine the meaning and scope of their own authority.

The challenge is to preserve the proper role of each institution.

---

The Difference Between Deference and Delegation

These concepts are closely related but should not be confused.

Delegation concerns what authority Congress gives an agency.

Deference concerns how a court reviews the agency’s exercise or interpretation of that authority.

Suppose Congress expressly gives an agency discretion to establish a technical standard within specified limits.

That is a delegation.

If a court reviews the agency’s policy choice and respects the range of choices Congress lawfully gave the agency, that is a question of judicial review and deference.

The existence of a delegation does not automatically mean that the agency gets to interpret every ambiguity in the statute.

After Loper Bright, courts independently determine the meaning of the statute and then determine the scope of any lawful delegation.

---

Deference and the Major Questions Doctrine

Administrative deference also intersects with the Major Questions Doctrine.

The doctrine addresses certain cases in which an agency claims significant regulatory power based on statutory language that Congress may not have clearly authorized it to use for that major action.

The doctrine reflects the principle that agencies should not assume enormous economic or political authority from vague statutory language.

This becomes especially important after Loper Bright.

The sequence can be understood conceptually:

First: What does the statute mean?

Second: What authority did Congress delegate?

Third: Does the claimed agency action fall within that authority?

Fourth: If discretion was delegated, did the agency exercise it through lawful and reasoned decision-making?

Deference cannot be used to skip those questions.

---

The Modern Post-Loper Bright Framework

The modern framework can be summarized in several stages.

Step One: Identify the legal question

Is the dispute about:

• statutory meaning;
• constitutional meaning;
• factual findings;
• agency discretion;
• procedural compliance; or
• policy choice?

Step Two: Interpret the governing statute independently

The court determines the best reading of the statute using traditional tools of statutory interpretation.

The agency does not receive controlling deference simply because the statute is ambiguous.

Step Three: Determine whether Congress delegated discretion

If Congress gave the agency discretionary authority, the court identifies the boundaries of that delegation.

Step Four: Review the agency’s action within those boundaries

The court examines whether the agency acted lawfully and engaged in reasoned decision-making.

Step Five: Apply the appropriate standard of review

Depending on the issue, the court may apply:

• independent judgment;
• arbitrary-and-capricious review;
• substantial-evidence review;
• abuse-of-discretion review; or another applicable standard.

This framework separates interpretive authority from administrative expertise and delegated discretion.

---

A Practical Example

Imagine Congress passes a statute directing an environmental agency to regulate industrial emissions that present a significant threat to public health.

The statute requires the agency to establish appropriate emission standards.

The agency adopts a regulation limiting a particular pollutant.

A regulated company challenges the regulation.

Several issues arise.

Issue 1: Does the statute cover this pollutant?

This is a question of statutory interpretation.

The court independently determines what the statute means.

Issue 2: Did Congress authorize the agency to establish emission standards?

The court determines the scope of the delegation.

Issue 3: Did the agency properly exercise that delegated authority?

The court examines the agency’s reasoning and compliance with the statutory framework.

Issue 4: Did the agency adequately consider scientific evidence?

The court reviews the administrative record under the applicable standard.

Issue 5: Was the agency’s chosen emission limit one of the lawful policy choices available to it?

If Congress delegated discretion, the court generally does not simply substitute its own preferred policy.

Issue 6: Did the agency explain its decision adequately?

The court may apply arbitrary-and-capricious review.

The agency therefore receives different degrees and types of judicial respect at different stages of the case.

A Comparison of Major Deference Doctrines

Doctrine	What Was Being Reviewed?	Basic Approach	Modern Status
Skidmore	Agency interpretation of law	Weight based on persuasiveness and expertise	Still relevant
Chevron	Agency interpretation of ambiguous statutes	Binding deference to reasonable agency interpretation under former framework	Overruled in 2024
Auer / Seminole Rock	Agency interpretation of its own regulation	Deference under specified conditions	Narrowed by Kisor
Kisor	Agency interpretation of its own regulation	Highly constrained deference after genuine ambiguity is established	Still relevant
Factfinding deference	Agency factual determinations	Judicial respect under applicable evidentiary standard	Still relevant
Policy-making review	Agency discretionary policy choices	Reasoned decision-making / arbitrary-and-capricious review	Still relevant

This table illustrates why the phrase “agency deference” can be misleading if used without identifying the particular doctrine involved.

---

What Agencies Can Still Expect From Courts

After Loper Bright, agencies should not assume that courts will automatically accept their statutory interpretations.

But agencies can still expect courts to recognize several legitimate aspects of administrative government.

Courts may recognize:

• technical expertise;
• factual knowledge;
• institutional experience;
• delegated discretion;
• reasoned policymaking;
• specialized factfinding; and
• persuasive interpretations.

The important change is that these considerations no longer allow an agency to claim automatic interpretive supremacy over statutory meaning.

---

What Regulated Parties Should Understand

For businesses, individuals, and organizations regulated by federal agencies, the modern doctrine has practical consequences.

A regulated party challenging agency action should distinguish between:

• “the agency interpreted the statute incorrectly”;
• “the agency exceeded its statutory authority”;
• “the agency made unsupported factual findings”;
• “the agency ignored relevant evidence”;
• “the agency failed to follow required procedures”; and
• “the agency exercised discretion arbitrarily.”

These are different arguments.

After Loper Bright, the first category is particularly important because the reviewing court must independently determine the statutory meaning.

---

Common Misconceptions

Misconception 1: Courts No Longer Respect Agencies

False.

Courts may still give substantial weight to agency expertise, factual findings, and lawful discretionary decisions.

What changed is the rule that statutory ambiguity automatically triggers binding deference.

Misconception 2: Chevron and All Deference Are the Same Thing

They are not.

Chevron was a particular doctrine concerning agency interpretations of ambiguous statutes.

Administrative deference is a broader concept.

Misconception 3: Loper Bright Made Agency Expertise Irrelevant

It did not.

Agency expertise may still make an interpretation persuasive and can be highly relevant to factual and technical questions.

Misconception 4: Agencies Can No Longer Exercise Discretion

They can.

Congress may lawfully delegate discretion to agencies.

The court’s role is to determine the boundaries of that delegation and ensure that the agency remains within them.

Misconception 5: Any Agency Interpretation Is Binding

It is not.

An agency’s interpretation may be persuasive without being legally controlling.

Misconception 6: Deference Means the Court Does Nothing

It does not.

Even deferential review requires the court to examine whether the agency acted within the law and satisfied the applicable standard.

Frequently Asked Questions

What does deference to administrative agencies mean?

It means that courts give some degree of judicial respect to agency decisions rather than automatically reconsidering every aspect of the agency’s work from the beginning. The degree of deference depends on the nature of the issue and the governing law.

Is Chevron deference still valid?

No. The Supreme Court overruled Chevron in Loper Bright Enterprises v. Raimondo in 2024. Courts must independently interpret federal statutes rather than defer automatically to agency interpretations merely because the statute is ambiguous.

Do courts still defer to administrative agencies?

Yes, in appropriate circumstances. Courts may give weight to agency expertise, defer to certain factual findings, respect lawful discretionary policymaking, and consider agency interpretations for their persuasive value.

What is Skidmore deference?

Skidmore refers to the principle that an agency’s interpretation may receive weight according to its power to persuade, considering factors such as reasoning, consistency, expertise, and thoroughness. It does not require the court to treat the agency’s interpretation as controlling.

What is Auer deference?

Auer or Seminole Rock deference historically concerned an agency’s interpretation of its own ambiguous regulation. The Supreme Court significantly limited this doctrine in Kisor v. Wilkie, requiring several conditions before deference is appropriate.

Does Loper Bright eliminate Skidmore?

No. Loper Bright expressly recognized that courts may continue to consider agency interpretations as persuasive assistance when independently interpreting statutes.

Can courts defer to agency factual findings?

Yes. The elimination of Chevron does not eliminate judicial deference to factual findings where the applicable law requires or permits such deference.

Can agencies still make policy?

Yes. Agencies may make policy within the authority Congress has lawfully delegated. Courts generally review such policymaking under applicable administrative-law standards rather than automatically replacing agency policy judgments with judicial preferences.

Why is agency deference controversial?

Because it involves a difficult balance between agency expertise and democratic accountability on one side and judicial responsibility for interpreting law and enforcing legal limits on the other. Excessive deference can concentrate power in administrative agencies, while insufficient respect for agency expertise can cause courts to intrude into functions Congress assigned to agencies.

Conclusion

Deference to administrative agencies has always reflected a tension at the heart of administrative law.

Agencies possess expertise, experience, technical knowledge, and practical responsibility for administering complex regulatory programs. Courts, however, possess the constitutional and statutory responsibility to determine whether governmental action is lawful.

The law has therefore never been simply about choosing between “agency power” and “judicial power.”

It is about determining which institution should decide which question.

The most significant modern development is Loper Bright. By overruling Chevron, the Supreme Court rejected the proposition that statutory ambiguity automatically authorizes an agency to determine the meaning of the law. Courts must exercise independent judgment when interpreting statutes.

But Loper Bright did not eliminate the administrative state, agency expertise, or every form of judicial deference.

Agencies may still exercise authority Congress has lawfully delegated. Their factual findings may receive appropriate judicial respect. Their technical judgments may be persuasive. Their policy choices may survive judicial review when supported by reasoned decision-making and grounded in lawful authority.

The modern principle can therefore be stated simply:

Agencies administer the law; courts determine what the law means and whether agencies have acted within the authority the law gives them.

That distinction provides the foundation for understanding the next major question in modern administrative law: what remains of Chevron after Loper Bright, and what did the Supreme Court’s rejection of Chevron mean for the constitutional structure of the administrative state?
