What Is Substantial-Evidence Review in a DOL 401(k) Case?

Substantial evidence is not the default standard for every factual disagreement involving DOL. It is a specific judicial-review standard tied to particular kinds of agency proceedings.

That threshold point matters more than the definition.

A court can face a factual dispute about:

• compliance cost
• fiduciary conduct
• prohibited transactions
• participant communications
• witness credibility
• market behavior
• agency economic analysis.

The existence of facts does not decide the review standard.

The first question is procedural:

What kind of agency action produced the finding?

For APA purposes, Section 706(2)(E) applies substantial-evidence review in a case subject to Sections 556 and 557 or otherwise reviewed on the record of an agency hearing provided by statute.^[1]

That is narrower than:

“any DOL case involving evidence.”

What Does Section 706(2)(E) Actually Cover?

Section 706 lists several distinct grounds for judicial review.^[1]

Subparagraph (E) directs courts to set aside agency action, findings or conclusions that are unsupported by substantial evidence in:

• cases subject to Sections 556 and 557
• or another proceeding for which the governing statute makes an agency hearing record the basis for judicial review.^[1]

The statutory cross-reference is the gate.

Sections 556 and 557 govern formal administrative hearing and decision procedures.^[2][3]

Those procedures can involve:

• presiding administrative law judges
• testimony
• documentary evidence
• a hearing record
• findings of fact
• conclusions
• agency review of an initial decision.

That procedural architecture looks much more like adjudication than ordinary notice-and-comment rulemaking.

A Normal DOL Rule Challenge Usually Starts Somewhere Else

Most major retirement regulations are adopted through notice-and-comment rulemaking under APA Section 553.

A typical sequence is:

proposed rule → public comments → final rule → judicial review.

The final rule can contain thousands of pages of factual material.

That still does not automatically make Section 706(2)(E) the governing standard.

For ordinary informal rulemaking, challenges commonly proceed under provisions such as:

• Section 706(2)(A): arbitrary, capricious, abuse of discretion or otherwise unlawful
• Section 706(2)(C): beyond statutory authority
• Section 706(2)(D): failure to follow required procedure.^[1]

That distinction was already visible in the 2018 Fiduciary Rule litigation.

In Chamber of Commerce v. DOL, the Fifth Circuit framed the challenge under statutory-authority and arbitrary-and-capricious provisions, including Sections 706(2)(A) and (C).^[12]

It was not a model Section 706(2)(E) formal-hearing case.

Why Is “Substantial Evidence” Often Used Too Loosely?

The phrase sounds ordinary.

A writer may say:

“DOL had substantial evidence for its rule.”

In everyday English, that can mean:

DOL had a lot of evidence.

That is not the same as invoking the statutory substantial-evidence standard.

Legal usage should be more disciplined.

There are at least three different statements:

1. DOL collected a substantial amount of evidence.
2. DOL's factual reasoning was adequately supported under arbitrary-and-capricious review.
3. An agency finding was supported by substantial evidence under Section 706(2)(E).

Those propositions can overlap.

They are not interchangeable.

What Does “Substantial Evidence” Mean?

Consolidated Edison Co. v. NLRB provides the classic formulation.^[4]

The Supreme Court said substantial evidence is:

• more than a mere scintilla
• relevant evidence that a reasonable mind could accept as adequate to support a conclusion.^[4]

The definition is deliberately less demanding than:

the reviewing court independently believes the fact is more likely true than false.

The court is not replacing the agency factfinder.

It is asking whether the agency finding clears a reasonableness threshold.

“More Than a Scintilla” Does Not Mean “A Lot”

The word:

substantial

can mislead.

The standard does not count pages, witnesses or exhibits.

Ten weak documents can provide less support than one credible contemporaneous record.

A finding can rest on:

• testimony
• documents
• expert analysis
• circumstantial evidence
• combinations of evidence

depending on the proceeding.

The core question is qualitative:

Could a reasonable factfinder accept this evidentiary record as adequate to support the conclusion?

That is why a record cannot be evaluated by volume alone.

Substantial Evidence Is Not Preponderance of the Evidence

These standards operate at different stages.

Preponderance

A factfinder decides whether a proposition is more likely than not.

Substantial-evidence review

A reviewing court asks whether the agency's factual finding has enough support that a reasonable factfinder could reach it.

The court may believe another factual conclusion is more persuasive.

That does not necessarily authorize reversal.

Substantial-evidence review gives the agency factfinder room to choose among reasonable views of conflicting evidence.

Burden of Proof and Review Standard Are Different Questions

Section 556 itself refers to burden of proof in formal hearings.^[2]

That creates a frequent category error.

Suppose the agency had to establish a violation by a specified burden.

The reviewing court later asks whether the agency's finding is supported by substantial evidence.

Those are two separate inquiries.

Agency-stage question

Did the party with the burden persuade the agency factfinder under the governing burden?

Court-review question

Is the resulting agency finding adequately supported under the applicable judicial-review standard?

The words:

burden

and:

standard of review

should not share one field in a case database.

Universal Camera Added the Whole Record

Consolidated Edison gives the familiar threshold.

Universal Camera Corp. v. NLRB explains how the threshold must be applied.^[5]

The Supreme Court rejected a one-sided approach under which a court could find some supporting evidence and stop.

The reviewing court must consider the record as a whole.^[5]

That includes evidence:

• supporting the agency finding
• detracting from the agency finding.

This is one of the most important limits on agency deference.

Substantial evidence is not:

find one favorable document and affirm.

Contrary Evidence Can Change Whether Support Is “Substantial”

Assume an agency finds:

Company knew Fact X on March 1.

Supporting evidence:

• one employee recalls a March conversation.

Contrary evidence:

• contemporaneous emails show no knowledge until April
• the employee's calendar contradicts the meeting date
• another witness denies the conversation
• the ALJ questions the employee's reliability.

The supporting testimony cannot be evaluated in isolation.

Universal Camera requires the court to consider the evidentiary picture as a whole.^[5]

The question becomes:

Does the supporting evidence remain substantial after the contrary record is taken seriously?

Sometimes yes.

Sometimes no.

The Whole Record Does Not Mean the Court Reweighs Everything From Scratch

Universal Camera strengthened review.

It did not turn courts into replacement ALJs.

The reviewing court must evaluate the entire record enough to determine whether the agency finding has substantial support.

But it does not simply decide:

Which side would have won in a fresh trial before this judge?

The agency remains the primary factfinder.

The court polices the reasonableness of that factfinding.

That is a meaningful middle position between:

• rubber-stamping
• de novo factual trial.

An ALJ's Findings Can Matter Even When the Agency Disagrees

Universal Camera also dealt with the role of the hearing examiner's findings.^[5]

The agency had rejected the examiner's view.

The Supreme Court held that the examiner's findings should not be treated as irrelevant to substantial-evidence review.^[5]

That does not make an ALJ's factual assessment automatically controlling.

It means the reviewing court considers the significance the ALJ's findings reasonably deserve in the whole record.

This can matter most when credibility is involved.

A presiding officer who directly heard testimony occupies a different evidentiary position from later agency reviewers reading a transcript.

Substantial-Evidence Review Can Uphold a Finding the Court Would Not Make

Suppose the record reasonably supports two conclusions:

A and B.

The agency selects A.

The reviewing judge personally finds B slightly more persuasive.

If A remains a conclusion a reasonable factfinder could reach on the whole record, substantial-evidence review does not let the judge replace A merely because B seems better.

That restraint is the point of the standard.

The agency's role would disappear if judicial review became:

pick the court's preferred inference.

Deference Does Not Mean Automatic Affirmance

The opposite error is just as serious.

If the evidence supporting A is:

• speculative
• contradicted by stronger objective evidence
• based on an inference the record cannot reasonably bear

the court can set the finding aside.

Universal Camera made clear that courts carry real responsibility for evaluating whether substantial evidence exists on the whole record.^[5]

The standard gives agencies room.

It does not give them immunity.

Dickinson v. Zurko Separates Court/Agency From Court/Court Review

Dickinson v. Zurko addressed Patent and Trademark Office factfinding.^[6]

The Federal Circuit had used a clearly-erroneous standard associated with review of trial-court findings.

The Supreme Court rejected that approach and held that the APA framework governs court review of agency findings.^[6]

The distinction is structural.

Court/court

An appellate court reviews a lower court's factual finding.

Court/agency

A court reviews an administrative agency's factual finding.

The labels should not be imported from one relationship into the other without legal authority.

Clearly Erroneous and Substantial Evidence Are Not Synonyms

The difference is not merely vocabulary.

A clearly-erroneous standard asks whether the reviewing court is left with the firm conviction that the lower court made a mistake.

Substantial-evidence review asks whether the agency's finding has enough evidentiary support for a reasonable factfinder.

Zurko described the APA's court/agency framework as somewhat more deferential than ordinary clearly-erroneous court/court review.^[6]

That distinction matters in appellate writing.

A sentence that says:

“The court reviews the agency's factual finding for clear error”

may be using the wrong framework.

Allentown Mack Shows That the Agency Must Apply Its Own Announced Standard

Allentown Mack Sales & Service v. NLRB involved an NLRB factual finding about whether an employer had a good-faith reasonable doubt concerning union support.^[7]

The Supreme Court concluded that the Board's factual finding lacked substantial evidence on the record as a whole.^[7]

The deeper lesson is more important than the labor-law facts.

An agency cannot announce one substantive standard and quietly demand proof of something stricter through its factual analysis.

Reviewing courts evaluate the evidence against the actual legal standard.

Hidden Policy Cannot Be Smuggled Into Factfinding

Suppose a DOL adjudication states that the legal test is:

reasonable basis.

But the agency effectively requires:

near certainty

before crediting the regulated party's evidence.

That is not merely a factual choice.

The agency may have altered the substantive standard without saying so.

Allentown Mack warns against that maneuver.^[7]

Factfinding cannot become a place where legal rules are silently rewritten.

The Agency's Fact Must Be Defined Before the Evidence Is Tested

Substantial-evidence analysis is impossible without identifying the proposition the agency actually found.

For example:

• Did a fiduciary know of a prohibited transaction?
• Did a plan administrator receive a required notice?
• Did a party act within a specified period?
• Did a transaction involve the listed entity?
• Did the respondent establish reasonable cause?

Each finding has its own legal elements.

The court must first know what fact was required.

Only then can it ask whether substantial evidence supports that finding.

Biestek Rejects Rigid Evidentiary Formulas

Biestek v. Berryhill involved Social Security disability adjudication and vocational-expert testimony.^[8]

The expert refused to provide underlying private market data.

The claimant argued that this refusal categorically prevented the testimony from counting as substantial evidence.

The Supreme Court rejected the categorical rule.^[8]

Substantiality depends on the record and circumstances.

That is a useful reminder for DOL proceedings.

The standard is not reducible to:

• expert supplied raw data = substantial
• expert withheld raw data = not substantial
• corroboration present = substantial
• hearsay present = automatically invalid.

The inquiry remains contextual.

Evidence Type and Evidence Weight Are Different

An administrative proceeding can admit evidence under rules that differ from federal trial evidence rules.

That does not mean every admitted item carries the same weight.

A hearsay document may be admitted.

A witness may testify from specialized experience.

A technical report may be accepted.

The review question is whether the whole record contains evidence a reasonable factfinder could rely on to reach the agency's conclusion.

Admissibility alone does not establish substantiality.

Substantial Evidence Can Exist Despite Conflicting Evidence

Conflict is normal.

If the record contains:

• credible evidence supporting the agency
• credible evidence opposing the agency

the agency can still prevail on substantial-evidence review.

The court asks whether the chosen finding remains reasonable.

It does not ask whether the agency eliminated every competing inference.

That makes the standard deferential.

But Universal Camera requires the opposing evidence to stay in the analysis.^[5]

A court cannot pretend the conflict does not exist.

What Role Does Agency Expertise Play?

Agencies often decide technical facts within specialized domains.

Expertise can matter because the agency may understand:

• industry practices
• technical terminology
• operational systems
• economic models
• regulatory context.

Substantial-evidence review respects that institutional role.

But expertise is not evidence by itself.

An agency cannot answer a factual challenge with:

“Trust the agency because the agency is expert.”

The record still has to support the conclusion.

A Technical Finding Can Be Reasonable Without Being Certain

Assume a formal DOL proceeding requires an agency factfinder to estimate the economic effect of a specific transaction.

The evidence includes:

• valuation reports
• industry data
• witness testimony
• competing expert opinions.

The agency chooses one reasonable valuation range.

A reviewing court does not require mathematical certainty.

It asks whether the chosen factual conclusion is supported by substantial evidence in the whole record.

Technical uncertainty does not automatically defeat agency factfinding.

Unsupported technical confidence can.

DOL Has Formal Adjudicatory Procedures

The substantial-evidence standard can feel remote from retirement regulation because most high-profile DOL litigation concerns rulemaking.

DOL also conducts formal adversarial adjudications.

29 CFR 18.101 states that Part 18 governs specified formal adversarial adjudications before a presiding officer, including proceedings required by Congress to be determined on the record after an agency hearing under APA Sections 554, 556 and 557, and proceedings that DOL regulations direct to conform to those provisions.^[9]

That is the procedural environment Section 706(2)(E) is designed to recognize.

ERISA Section 502(i) Proceedings Provide a Concrete DOL Example

29 CFR 2570.1 applies special rules to prohibited-transaction penalty proceedings under ERISA Section 502(i).^[10]

The regulation states that DOL's OALJ procedural rules in Part 18 apply except as modified by the ERISA-specific provisions.^[10]

Section 2570.2 describes the proceeding as a judicial-type adjudicatory proceeding leading to a final order.^[11]

It also states that a qualifying final order constitutes final agency action under APA Section 704.^[11]

This is much closer to a classic administrative adjudication than a Federal Register rulemaking.

What Does a Formal DOL Adjudication Look Like?

A formal administrative proceeding can involve:

• notice
• pleadings
• discovery under applicable rules
• motions
• evidentiary submissions
• witnesses
• an ALJ
• findings of fact
• conclusions of law
• an administrative decision
• possible review within the Department
• final agency action.

That architecture creates identifiable agency factual findings.

A court can then review those findings under the statutory standard that applies to the proceeding.

The standard still has to be established from the governing law.

The existence of an ALJ alone should not be treated as a magic word.

Part 2570 Should Not Be Generalized to Every 401(k) Case

ERISA covers many kinds of disputes.

A 401(k) case can involve:

• private fiduciary litigation
• benefit claims
• DOL civil enforcement
• agency penalties
• prohibited transactions
• rulemaking
• exemptions
• advisory opinions.

Those proceedings do not all use Part 2570.

They do not all produce the same record.

They do not all receive Section 706(2)(E) review.

The procedural source must be identified before the standard is named.

Rulemaking Facts Are Usually Reviewed Through Reasoned Decisionmaking

Return to a familiar DOL rule challenge.

Assume DOL adopts a retirement rule after concluding:

• conflicted recommendations cause measurable harm
• compliance costs are manageable
• the rule will improve participant outcomes.

Industry challengers dispute every factual premise.

That does not automatically create a substantial-evidence case.

For ordinary notice-and-comment rulemaking, the challenge is generally framed through arbitrary-and-capricious review.

The court asks whether DOL:

• examined relevant data
• considered important issues
• responded to serious comments
• explained assumptions
• connected facts to policy.

That is the State Farm lane discussed in INV-208.

“Unsupported by Evidence” and “Unsupported by Substantial Evidence” Are Not Always the Same Legal Claim

A brief may say:

“The rule is unsupported by evidence.”

That phrase can describe an arbitrary-and-capricious argument.

It does not necessarily invoke Section 706(2)(E).

A careful summary should look at:

• statutory provision cited
• type of agency proceeding
• case law invoked
• remedy requested.

A challenge to an informal DOL rule can attack weak evidence without being a substantial-evidence case in the statutory sense.

Chamber of Commerce Shows Why the Provision Matters

The Fifth Circuit's 2018 Fiduciary Rule decision is a useful DOL example.^[12]

The court addressed:

• statutory meaning
• agency authority
• reasonableness
• arbitrary-and-capricious concerns.

Its concluding APA discussion focused on Sections 706(2)(A) and (C).^[12]

That is instructive.

The dispute involved massive factual and economic material.

Yet the type of agency action and legal claims drove the review framework.

Evidence volume did not convert the case into Section 706(2)(E).

Substantial-Evidence Review Is Not Loper Bright Review

Loper Bright concerns independent judicial interpretation of statutes.

Substantial evidence concerns specified agency factfinding.

A court can therefore:

• independently interpret ERISA
• deferentially review agency facts under substantial evidence where applicable.

Those two standards can coexist.

A sentence saying:

“After Loper Bright, courts no longer defer to agency factfinding”

is wrong.

The Supreme Court changed statutory interpretation.

It did not erase APA fact-review standards.

Substantial-Evidence Review Is Not Firestone Review

Firestone addresses judicial review of certain private ERISA benefit denials.

That framework depends in part on whether the plan grants the administrator discretionary authority.

Substantial-evidence review under the APA concerns agency factfinding in specified administrative proceedings.

The decisionmaker changes:

Firestone context

Plan administrator or fiduciary.

APA substantial-evidence context

Federal agency.

The source of law changes too.

Similar words about deference should not obscure that structural difference.

Substantial Evidence Is Not the Same as “Abuse of Discretion” in a Benefit Case

Some ERISA benefit cases use substantial-evidence language while applying a deferential plan-administrator review framework.

That does not make those cases Section 706(2)(E) APA cases.

Courts sometimes use the phrase:

substantial evidence

to describe the level of support expected under another doctrine.

The legal source must still be identified.

This is another reason keyword searches can mislead.

The phrase alone does not tell the reader which review regime applies.

Worked Example: Informal DOL Rule With Weak Cost Evidence

DOL adopts a 401(k) disclosure rule.

The final rule estimates:

$150 million

in annual implementation cost.

Industry comments estimate:

$900 million.

A challenger says:

“The rule lacks substantial evidence.”

Before treating that as a Section 706(2)(E) claim, ask:

• Was the rule adopted through Section 553 notice-and-comment?
• Was there a formal hearing required by statute?
• Is the complaint actually invoking Section 706(2)(A)?

If this is ordinary informal rulemaking, the sharper question is likely whether DOL's cost analysis was arbitrary and capricious.

Worked Example: Formal ERISA Penalty Proceeding

A DOL administrative penalty proceeding turns on whether a respondent knew specific facts about a prohibited transaction.

The record contains:

• emails
• testimony
• transaction documents
• competing explanations.

The ALJ finds knowledge.

The agency issues final action after the applicable administrative process.

A reviewing court should identify the governing hearing statute and APA provisions.

If Section 706(2)(E) applies, the question is whether the knowledge finding is supported by substantial evidence on the whole record.

The court does not retry knowledge from scratch.

Worked Example: Some Evidence Exists, but the Whole Record Cuts the Other Way

Agency finding:

Respondent received Notice X on January 3.

Supporting evidence:

• undated internal note saying notice was sent.

Contrary evidence:

• certified-mail record shows January 18
• recipient log shows January 19
• agency witness cannot identify January 3 mailing
• electronic record was created January 17.

A court cannot stop at:

“There is a note.”

Universal Camera requires the entire record to be assessed.^[5]

The note may be too weak to remain substantial after the contrary evidence is considered.

Worked Example: Two Reasonable Conclusions

Agency finding:

Transaction was negotiated before the deadline.

The record contains:

• emails suggesting negotiation began early
• a later draft suggesting terms remained unsettled
• witness testimony supporting both interpretations.

A reviewing judge might think the later date is slightly more likely.

That is not enough.

If the agency's early-date finding remains reasonable on the whole record, substantial-evidence review supports affirmance.

The court is reviewing, not deciding first instance.

Worked Example: Hidden Higher Burden

DOL announces that a respondent can prevail by showing:

reasonable cause.

The record contains credible evidence establishing uncertainty and documented compliance steps.

The agency rejects the defense because the respondent failed to prove:

absolute impossibility.

That may not be a simple evidence-weighting decision.

The agency may have changed the substantive standard.

Allentown Mack shows why the court should compare the factual analysis with the legal rule the agency says it is applying.^[7]

Worked Example: Court Uses the Wrong Court/Court Standard

An appellate panel says:

“The agency's finding will be reversed only if clearly erroneous.”

If the governing statute calls for substantial-evidence review, Zurko warns against importing the district-court factfinding standard.^[6]

The reviewing relationship matters.

Agency factfinding is governed by the administrative-review framework Congress supplied.

The wrong label can produce too much or too little deference.

How Much Evidence Is Enough?

There is no numerical answer.

Biestek is valuable because it rejects rigid formulas.^[8]

A record can contain substantial evidence even when:

• the evidence is not perfect
• some supporting data are unavailable
• contrary evidence exists.

A record can fail even when:

• several documents support the agency
• an expert testified
• the agency's conclusion is plausible in the abstract.

The entire evidentiary setting matters.

Credibility Can Matter Without Becoming Unreviewable

Administrative factfinding can depend on credibility.

A presiding ALJ may observe:

• demeanor
• hesitation
• consistency
• responsiveness.

Those observations can carry weight.

But credibility labels do not eliminate review.

A finding that says:

“Witness A is credible”

still has to fit the whole record.

Objective contradictions can matter.

Universal Camera's treatment of the hearing examiner reinforces that credibility findings are relevant, not untouchable.^[5]

Documentary Evidence Can Outweigh Testimony

Suppose a witness testifies that a required plan communication was delivered on time.

Contemporaneous system logs show no delivery.

The agency may explain why it credits the witness.

But the documentary conflict matters to substantiality.

A reviewing court should evaluate:

• reliability of system records
• witness basis of knowledge
• timing
• corroboration
• agency explanation.

Substantial evidence is not a witness-counting test.

Agency Expertise Does Not Permit a Different Definition of the Fact

Allentown Mack makes another point worth preserving.^[7]

An agency can use expertise to evaluate evidence.

It cannot use expertise to turn:

reasonable doubt

into:

near certainty

without changing the legal standard.

For DOL, technical expertise can inform:

• valuation
• fiduciary process
• market practice
• regulatory consequences.

It cannot silently redefine the statutory element the agency must decide.

Whole-Record Review Should Be Documented Explicitly

A strong case summary should identify:

Agency finding

What exact fact did DOL find?

Supporting evidence

Which record items support it?

Contrary evidence

Which record items detract from it?

Factfinder treatment

How did the ALJ or agency explain the conflict?

Governing burden

What burden applied at the agency level?

Judicial standard

What statute governs court review?

Result

Did the court find substantial evidence on the whole record?

This structure prevents vague statements such as:

“The evidence supported DOL.”

A Practical Standard-Selection Matrix

The row matters more than the word:

evidence.

Substantial-Evidence Review Checklist

Before labeling a DOL or 401(k) issue a substantial-evidence case, verify:

1. Agency action

What exact DOL decision is under review?

2. Proceeding type

Was it:

• Section 553 informal rulemaking
• formal adjudication
• statutory hearing
• penalty proceeding
• exemption process
• another action?

3. Formal-hearing trigger

Are Sections 556 and 557 applicable?

4. Governing statute

Does another statute require review on an agency hearing record?

5. Exact factual finding

What proposition did the agency find?

6. Substantive legal standard

What fact did the governing rule actually require?

7. Agency burden

Who had to prove what during the agency proceeding?

8. Supporting evidence

What record evidence supports the finding?

9. Contrary evidence

What evidence detracts from it?

10. Whole-record treatment

Did the agency address the central conflict?

11. ALJ findings

Were credibility or examiner findings accepted or rejected?

12. Court/agency standard

Is Section 706(2)(E) actually the review provision?

13. Other APA claims

Are statutory authority, procedure or arbitrary-and-capricious arguments separate?

14. Prejudice

Would any evidentiary defect matter to the outcome?

15. Remedy

What should happen if the finding lacks substantial evidence?

That sequence makes the standard auditable.

Fast Answers

What is substantial evidence?

More than a mere scintilla; evidence a reasonable mind could accept as adequate to support a conclusion.^[4]

Does substantial evidence mean more likely than not?

Not as a judicial-review standard.

Is substantial evidence the same as preponderance?

No.

Does Section 706(2)(E) apply to every DOL case?

No.

When does Section 706(2)(E) apply?

When Sections 556 and 557 govern the proceeding, or when another statute requires judicial review on the record of an agency hearing.^[1]

Does an ordinary notice-and-comment DOL rule automatically use substantial-evidence review?

No.

What standard usually matters in an informal rule challenge?

Depending on the claim, arbitrary-and-capricious review, statutory-authority review and procedural review are common.^[1][12]

What did Universal Camera add?

The court must assess substantial evidence on the record as a whole, including evidence that detracts from the agency finding.^[5]

Can a court affirm if contrary evidence exists?

Yes, if the agency's finding remains one a reasonable factfinder could reach on the whole record.

Can a court reverse even if some supporting evidence exists?

Yes, if the support is not substantial when the whole record is considered.^[5]

What did Zurko clarify?

Court/agency fact review under the APA is not automatically the same as clearly erroneous appellate review of trial-court findings.^[6]

What did Allentown Mack show?

The agency's factual findings must satisfy the substantive standard the agency actually announces; policy cannot be hidden inside distorted factfinding.^[7]

What did Biestek show?

Substantial evidence is context dependent and not governed by one categorical evidentiary formula.^[8]

Does DOL conduct formal adjudications?

Yes. Part 18 governs specified formal adversarial DOL adjudications, including proceedings conducted under or in conformance with APA Sections 554, 556 and 557.^[9]

Is there an ERISA example?

Yes. Part 2570 includes ERISA Section 502(i) prohibited-transaction penalty proceedings using OALJ procedures.^[10][11]

Does that mean every 401(k) case uses Part 2570?

No.

Is substantial-evidence review the same as Firestone benefit review?

No.

Did Loper Bright eliminate factual deference?

No. It changed statutory-interpretation doctrine, not the APA's separate factual-review provisions.

What is the safest one-sentence rule?

Before invoking substantial evidence in a DOL or 401(k) case, identify the agency proceeding and exact factual finding first; Section 706(2)(E) is a specialized whole-record review standard for specified on-the-record agency factfinding, not a general synonym for whether DOL had persuasive evidence.

The burden of proof, administrative evidentiary rules, final agency action, judicial review standard, prejudice and remedy require separate analysis. Current disputes should be evaluated against the applicable statute, agency regulation, hearing record, final order and controlling circuit precedent.
