What Is Precedent and Stare Decisis for DOL 401(k) Rules?

Precedent attaches to the legal rule a court actually decided—not to every sentence in the opinion, the size of the case or the breadth of the remedy.

That distinction matters immediately in DOL litigation.

A single case can produce all of these at once:

• a binding legal holding
• persuasive reasoning beyond the holding
• a case-specific judgment
• a nationwide operational consequence for a federal rule
• unresolved questions left for another court or another case.

Treating those five things as interchangeable is how a litigation update becomes a bad compliance memo.

Start With the Court, Not the Headline

Federal precedent has a hierarchy.

For a federal ERISA or APA question:

Supreme Court holding → controls lower federal courts nationwide

Federal court of appeals holding → ordinarily controls federal district courts within that circuit

Federal district-court decision → can be persuasive and can control the parties through its judgment, but does not become nationwide appellate precedent.

That hierarchy does not tell the entire story.

A court also has to identify:

• what issue was actually decided
• whether the relevant language was necessary to the judgment
• whether five Supreme Court Justices joined the rationale
• whether the judgment was later vacated or superseded
• whether a later en banc or Supreme Court decision changed the rule
• whether Congress amended the statute.

The citation alone is not enough.

Vertical Stare Decisis Makes Supreme Court Holdings Controlling

The Supreme Court's rule for lower courts is unusually clear.

In Agostini v. Felton, the Court rejected the idea that lower courts can treat an older Supreme Court precedent as silently overruled because later decisions seem inconsistent with its reasoning.^[1]

The lower court must follow the decision that directly controls and leave overruling to the Supreme Court itself.^[1]

That matters in retirement regulation because doctrinal change often occurs in stages.

Suppose an older Supreme Court case interpreted an ERISA term.

Later Supreme Court cases change:

• administrative-law methodology
• statutory interpretation principles
• deference doctrine.

A district court cannot simply announce:

"The old ERISA case looks inconsistent with the new trend, so it no longer controls."

The correct question is whether:

• the Supreme Court actually overruled the earlier holding
• Congress changed the statute
• the earlier case is materially distinguishable.

Doctrinal tension is not the same as overruling.

Supreme Court Precedent Is About Federal Law, Not the Geography of the Case

A Supreme Court holding interpreting ERISA does not bind only:

• the circuit from which the case came
• the district court on remand
• the specific parties.

The legal rule is national federal precedent.

That is why a Supreme Court DOL case can matter to plans far outside the original litigation.

Perez v. Mortgage Bankers Association did not involve a 401(k) rule.^[5]

It involved DOL's Wage and Hour Division and the APA treatment of interpretive rules.

The Court rejected the D.C. Circuit's Paralyzed Veterans doctrine, which had required notice and comment before an agency could significantly revise a definitive interpretation of its own regulation.^[5]

That holding is not confined to mortgage-loan officers.

It is Supreme Court administrative-law precedent.

The principle can matter when evaluating another federal agency's interpretive-rule procedure because the Court resolved a federal APA question.

The underlying program was narrow.

The legal rule was broader.

Circuit Precedent Has a Different Geographic Reach

A federal court of appeals creates binding appellate precedent within its circuit, subject to:

• later en banc action
• intervening Supreme Court authority
• valid statutory change
• the circuit's rules for when an intervening decision is sufficiently contrary to supersede prior panel law.

The Fifth Circuit is especially explicit about its internal rule of orderliness: one panel ordinarily does not overrule an earlier panel merely because the later panel thinks the earlier case was wrong.

That discipline matters in DOL litigation because many major retirement-rule cases have arisen in the Fifth Circuit.

But this statement needs a boundary:

Fifth Circuit precedent is not Supreme Court precedent.

A Fifth Circuit statutory interpretation can be binding in federal courts within:

• Texas
• Louisiana
• Mississippi.

Another circuit may adopt the same interpretation.

It may disagree.

Until the Supreme Court or Congress resolves the issue, federal law can develop differently across circuits.

A Nationwide Rule Does Not Make Circuit Precedent Nationwide

This is one of the easiest mistakes to make in federal regulatory litigation.

DOL issues one nationwide regulation.

The Fifth Circuit invalidates it.

The judgment produces nationwide operational consequences for the rule.

A memo then says:

"The Fifth Circuit's legal reasoning is now binding nationwide."

That does not follow.

The first question concerns:

remedy.

The second concerns:

precedent.

They are different.

In Chamber of Commerce v. Department of Labor, the Fifth Circuit held that DOL exceeded its authority in the 2016 fiduciary-rule package and vacated the rule.^[7]

DOL later treated the Fifth Circuit mandate as vacating the regulatory package.

The operational consequence was national because the object being vacated was a national federal rule.

But the Fifth Circuit did not thereby transform itself into the Supreme Court.

Its legal holdings remained circuit precedent.

The remedy and the precedent traveled differently.

INV-215 covers the scope-of-relief problem.

For precedent analysis, the rule is simpler:

Do not infer precedential scope from remedial breadth.

District-Court Orders Can Matter Without Becoming Appellate Precedent

A district judge can enter an order that dramatically changes current rule status.

For example, a district court may:

• stay agency action
• enjoin enforcement
• vacate a rule
• enter declaratory relief.

That order can matter immediately to:

• DOL
• regulated parties
• the rule's effective status.

But the legal reasoning does not become binding on every other district court merely because the order has broad practical effect.

Another district judge may:

• find the reasoning persuasive
• distinguish it
• reject it
• be bound by different circuit precedent.

This is why a current-law tracker needs two fields:

A single field labeled:

"case outcome"

is too crude.

Holding and Dicta Are Not the Same Thing

A court opinion can contain:

• the rule necessary to decide the case
• explanatory observations
• historical discussion
• hypotheticals
• commentary on issues not required for the judgment.

The core binding proposition is the holding.

The term dicta generally describes statements not necessary to the result.

That does not mean dicta is useless.

Supreme Court dicta can be highly influential.

A lower court may treat carefully reasoned language as a strong signal.

But the analysis should not flatten the distinction.

Consider a Supreme Court opinion that says:

ERISA does not authorize DOL to impose Rule X.

That proposition is necessary to a judgment invalidating Rule X.

The same opinion adds:

"A differently designed disclosure rule might raise fewer concerns."

Unless that second question was necessary to the judgment, it should not automatically be reported as:

"The Supreme Court approved the alternative disclosure rule."

It did not.

The Result Alone Does Not Define the Holding

The judgment tells what happened to the case.

The opinion explains why.

That distinction becomes critical when multiple Justices agree on the result for different reasons.

Imagine:

• four Justices say DOL lacks statutory authority
• one Justice says the plaintiff lacks standing but concurs in the judgment
• four Justices would uphold the rule.

Five Justices voted for the same judgment.

But five did not agree that DOL lacked authority.

A summary that says:

"The Supreme Court held 5-4 that DOL exceeded ERISA authority"

would be wrong.

The vote on the judgment and the vote on the rationale are separate.

Majority Opinions Are the Easy Case

When five or more Justices join the same reasoning necessary to the judgment, precedent analysis is comparatively straightforward.

The controlling opinion identifies:

• the question
• the rule
• the application necessary to resolve the case.

Separate concurrences and dissents may still matter for:

• future litigation strategy
• potential doctrinal movement
• how later courts understand unresolved questions.

But they do not displace the majority holding.

A 6-3 decision with a six-Justice majority is not legally transformed because the dissent is forceful.

A Concurrence Is Not Automatically Controlling

A Justice can concur:

• in the opinion
• in part of the opinion
• only in the judgment.

Those are different.

A concurrence in the judgment may reject the majority's reasoning while agreeing with the result.

If five Justices join the majority rationale, the separate concurrence is not controlling.

If no rationale has five votes, fragmented-opinion analysis becomes harder.

That is where Marks v. United States enters.^[2]

Marks Addresses Fragmented Supreme Court Decisions

Marks gives the familiar rule:

when no single rationale explaining the result receives five votes, the Court's holding may be viewed as the position taken by the Justices who concurred in the judgment on the narrowest grounds.^[2]

That sounds mechanical.

It often is not.

The phrase:

"narrowest grounds"

works best when one rationale is logically contained inside a broader rationale.

Example:

• three Justices would invalidate every version of a DOL practice
• two Justices would invalidate only the version before the Court for a narrower reason
• four would uphold it.

If the narrower rationale is a true subset of the broader one, it may supply the controlling rule under Marks.

But not every fragmented decision has that structure.

Hughes v. United States Shows the Limit of Mechanical Marks Analysis

Hughes v. United States addressed how to understand a fractured earlier decision.^[3]

The Court rejected the idea that every plurality can be forced into a clear controlling rule simply by locating the opinion that looks factually narrowest.

The useful point for DOL analysis is not the criminal-sentencing subject matter.

It is the method.

When Supreme Court rationales do not share a common denominator, a compliance writer should not manufacture one.

The correct statement may be:

"The Court produced a fragmented result without a single majority rationale controlling this broader question."

That is less dramatic.

It is more accurate.

Dissents Are Not Precedent

A dissent can later:

• influence scholarship
• persuade future judges
• become the basis for a later majority
• identify weaknesses that Congress addresses.

At the time it is issued, it is not the governing holding.

This matters when a major administrative-law case generates sharply opposed opinions.

A retirement article should not write:

"The Supreme Court recognized that DOL has broad authority to..."

if that proposition appears only in the dissent.

The attribution must be explicit:

"The dissent argued..."

That preserves the legal status of the statement.

Stare Decisis Does Not Mean Precedent Can Never Change

Stare decisis is a doctrine of adherence to precedent.

It is not an absolute prohibition on overruling.

The Supreme Court can overrule its own precedent.

An en banc court of appeals can overrule circuit panel precedent subject to governing doctrine.

Congress can amend a statute and change the statutory text that an earlier case interpreted.

That means a precedent-status review must ask:

What happened after the cited case?

A perfect quotation from an overruled decision is still an obsolete rule.

Loper Bright Is the Best Current Example of Why Methodology and Holdings Must Be Separated

Loper Bright Enterprises v. Raimondo overruled Chevron's deference framework.^[4]

After Loper Bright, courts must exercise independent judgment when deciding the meaning of statutes administered by federal agencies.^[4]

That was a major methodological change.

It did not mean:

every case that ever cited Chevron disappeared.

The Court addressed that point directly.

It said that prior holdings finding specific agency actions lawful remain subject to ordinary statutory stare decisis despite the change in interpretive methodology.^[4]

That sentence is unusually important for DOL research.

"Cited Chevron" Is Not a Valid Obsolescence Test

Suppose a 2012 appellate case upheld a DOL regulation.

The opinion used Chevron.

A 2026 research note says:

"Loper Bright overruled Chevron, so the 2012 DOL holding is no longer law."

That is too broad.

The correct analysis asks:

1. What did the earlier court actually hold?
2. Was the holding that a specific agency action was lawful?
3. Has that holding itself been overruled?
4. Did an intervening Supreme Court decision make the result irreconcilable?
5. Did Congress change the governing statute?
6. Does circuit precedent doctrine treat the intervening authority as superseding the old rule?

Loper Bright itself warns against the shortcut.^[4]

Methodology Can Change While a Specific Result Remains Precedent

This can feel counterintuitive.

An earlier court may have reached result A using method B.

The Supreme Court later rejects method B.

Result A does not always automatically vanish.

Why?

Because precedent is not merely a record of reasoning techniques.

A prior case may contain a specific statutory holding that has its own stare decisis weight.

That is exactly the distinction Loper Bright preserved.^[4]

For ROIStreet content, the safe phrasing is:

"Loper Bright eliminated Chevron deference; separate analysis is still required to determine whether an earlier case's specific statutory holding remains controlling."

Loper Bright Also Limits What DOL Can Do by Regulation

After Loper Bright, a federal court does not treat statutory ambiguity as an automatic delegation to DOL.^[4]

The court must determine:

• what ERISA means
• whether Congress actually delegated discretion
• the boundaries of that discretion.

If the Supreme Court has already definitively interpreted the statute, DOL cannot issue a regulation declaring:

"The Supreme Court's interpretation was wrong; the statute means the opposite."

An agency is not hierarchically above the Supreme Court.

But this boundary should not be overstated.

A New DOL Rule Can Still Be Lawful After a Judicial Decision

A controlling case may decide only:

• one statutory question
• one version of a rule
• one record
• one rationale.

A later rule may differ materially.

Congress may also have delegated genuine policymaking discretion.

Then DOL may be able to choose among lawful options inside that delegation.

The question is not:

"Did a court ever rule against DOL on this subject?"

It is:

"What proposition did the court hold, and does the new agency action conflict with it?"

That is a much tighter test.

Congress Can Change a Statutory Rule

A Supreme Court statutory interpretation is authoritative as to the statute the Court interpreted.

Congress retains legislative power to amend the statute within constitutional limits.

If Congress changes ERISA text, the old judicial interpretation may no longer answer the new statutory question.

Example:

Court holds:

"Existing Section X does not authorize DOL to regulate transaction Y."

Congress later amends Section X to expressly authorize regulation of transaction Y.

The agency is not overruling the Court.

Congress changed the law.

The next case interprets the amended statute.

That is different from DOL attempting to reverse a judicial holding by agency assertion alone.

Hughes v. Northwestern Shows How a Supreme Court Holding Can Be Binding but Incomplete

Hughes v. Northwestern University is especially useful for 401(k) readers because it involved defined-contribution retirement plans.^[6]

Participants alleged that plan fiduciaries breached ERISA's duty of prudence through excessive fees and imprudent investment options.

The Seventh Circuit had relied in part on the idea that participants could choose lower-cost options from a broad menu.

The Supreme Court rejected that categorical reasoning.^[6]

It emphasized that ERISA's duty of prudence includes the duty to monitor investments and remove imprudent ones.^[6]

Then the Court:

vacated the judgment and remanded.^[6]

That sequence matters.

Hughes Did Not Decide Every Allegation in the Participants' Favor

A weak summary says:

"The Supreme Court held Northwestern's plan was imprudent."

That overstates the decision.

The Court held that the lower court used flawed categorical reasoning and directed reconsideration under the proper context-specific ERISA standard.^[6]

The controlling legal principle came from the Supreme Court.

The factual application continued below.

This is a recurring appellate pattern:

binding legal rule + unresolved application + remand.

A remand is not doctrinal emptiness.

Nor is it a complete merits victory on every factual contention.

A Remand Does Not Let the Lower Court Ignore the Appellate Holding

When an appellate court resolves a legal issue and sends the case back, the lower court must conduct further proceedings consistent with that decision.

That obligation in the same case is often discussed through:

• mandate doctrine
• law of the case.

Those concepts overlap with precedent in practice but are not identical to stare decisis.

Stare decisis asks:

What rule governs other cases?

The mandate asks:

What must this lower court do in this case after the appellate judgment?

A litigation tracker should keep those separate.

Vacatur Changes the Status of the Lower Judgment

The word:

vacated

should never be treated as decoration.

Vacatur nullifies the judgment being vacated for the purposes of the appellate disposition and often clears the way for further proceedings or relitigation.^[9][10]

The consequences depend on:

• which judgment was vacated
• why
• what the appellate court ordered next.

This is where summaries frequently identify the wrong object.

A court may vacate:

• an agency rule
• a district-court judgment
• an appellate judgment.

Those are not equivalent.

Vacating the Lower Judgment Does Not Erase the Appellate Court's Own Holding

Suppose the Supreme Court says:

"The circuit applied the wrong legal test. Judgment vacated and remanded."

The circuit's prior judgment is displaced.

The Supreme Court's legal holding remains the controlling instruction.

Hughes v. Northwestern follows that pattern.^[6]

This is why the database should contain separate fields for:

• court issuing opinion
• legal holding
• object vacated
• remand instruction.

One field labeled:

"vacated"

cannot do the work.

Vacatur for Mootness Has Its Own Function

United States v. Munsingwear and U.S. Bancorp Mortgage Co. v. Bonner Mall Partnership address vacatur when appellate review is frustrated by mootness.^[9][10]

The Munsingwear concept is designed in appropriate circumstances to clear a judgment whose review became impossible through events that prevented appellate merits review.^[10]

Bancorp explains that vacatur is equitable and is not automatically available when the party seeking relief caused mootness through settlement.^[9]

For precedent tracking, the key lesson is narrower:

Do not cite a vacated judgment as though its appellate status were unchanged.

Check why it was vacated and what remains.

INV-212 covers mootness in more depth.

Reversal and Vacatur Are Not Synonyms

A court may:

• affirm
• reverse
• vacate
• modify
• remand
• combine those forms of relief.^[12]

A reversal says the lower judgment is wrong in the respect resolved by the appellate court.

Vacatur sets aside the judgment.

Remand sends the case back for additional action.

The Supreme Court can:

reverse and remand

or:

vacate and remand.

Those formulations should be reported exactly.

They can signal different procedural consequences.

Denial of Certiorari Has No Supreme Court Merits Holding

INV-219 covers this directly.

A Supreme Court order denying certiorari does not affirm the lower court's reasoning on the merits.^[11]

The lower judgment remains in place.

But the Supreme Court has not created a new merits precedent approving it.

This sentence is wrong:

"The Supreme Court upheld the Fifth Circuit by denying certiorari."

The correct sentence is:

"The Supreme Court denied review, leaving the Fifth Circuit judgment in place."

That distinction matters whenever the lower decision is being cited outside its circuit.

Persuasive Authority Still Matters

Not every useful case is binding.

A DOL 401(k) issue may have:

• no Supreme Court case
• no controlling circuit decision
• several decisions from other circuits
• conflicting district-court opinions.

Those authorities can be persuasive.

Their weight can depend on:

• quality of reasoning
• similarity of statutory text
• factual fit
• position in the federal hierarchy
• consistency with controlling precedent
• whether later cases adopted or rejected the reasoning.

Calling an authority:

persuasive

is not an insult.

It is a jurisdictional description.

Market Synergy and Chamber of Commerce Show Why Related Cases Must Be Separated

The Tenth Circuit's Market Synergy Group v. Department of Labor and the Fifth Circuit's Chamber of Commerce decision arrived within days of one another in 2018.^[7][8]

Both concerned the 2016 fiduciary regulatory package.

They did not resolve identical legal questions.

Market Synergy addressed DOL's treatment of fixed indexed annuities under amended PTE 84-24 and rejected the challenges before it.^[8]

Chamber of Commerce held more broadly that DOL's expanded fiduciary definition exceeded statutory authority and vacated the package.^[7]

A research note should not compress those outcomes into:

"Tenth Circuit says rule valid; Fifth Circuit says rule invalid."

The unit of precedent is the legal issue actually decided.

Different portions of the same regulatory package can produce different holdings without creating a clean conflict on every question.

A Circuit Split Requires Conflict on the Same Legal Question

INV-219 addresses circuit conflicts in the certiorari context.

The same discipline applies here.

To identify a true split, compare:

• statutory provision
• legal test
• procedural posture
• materially comparable facts
• actual holding.

Do not compare:

outcome A

against:

outcome B

and stop.

A court can uphold one exemption and another court can invalidate a separate definition without adopting conflicting rules of law.

Precedent Does Not Automatically Equal Current Compliance

A court can establish a controlling legal principle while current DOL obligations remain dependent on later steps.

After a major opinion, check:

• judgment
• stay status
• mandate or Rule 45 transmission
• remand
• agency response
• Federal Register action
• current CFR text
• current DOL enforcement position.

A Supreme Court opinion may control legal interpretation before DOL has updated its website.

A lower court may still need to enter a new judgment on remand.

The agency may need to amend codified text.

Current-law analysis requires both:

precedent

and:

implementation status.

Worked Example: Loper Bright Is Treated as a Mass Deletion Command

Research database contains 40 pre-2024 DOL cases that mention Chevron.

Editor marks all 40:

"overruled."

That is indefensible.

Loper Bright overruled the Chevron framework.^[4]

It expressly said prior holdings that specific agency actions were lawful were not automatically called into question merely because the cases relied on Chevron.^[4]

Each case needs separate later-history analysis.

The correct update flag is:

"Chevron methodology superseded; verify continuing force of specific holding."

Not:

"case erased."

Worked Example: Nationwide Vacatur Is Treated as Nationwide Circuit Precedent

Fifth Circuit vacates a national DOL rule.

Compliance note says:

"Every federal court is now bound by the Fifth Circuit's ERISA interpretation."

Wrong category.

The rule may be gone nationally because of the remedy.

The Fifth Circuit's precedential hierarchy has not changed.

Another circuit facing a later materially similar statute or new DOL rule must still determine the controlling law in that circuit, subject to Supreme Court authority.

Operational reach and precedential reach are separate.

Worked Example: A Concurrence Is Counted as the Fifth Majority Vote

Supreme Court disposition:

• four Justices join rationale A
• one Justice concurs in judgment on rationale B
• four Justices dissent.

Article says:

"Five Justices adopted rationale A."

No.

Five Justices agreed on the result.

Only four adopted A.

The next step is fragmented-opinion analysis under Marks, informed by Hughes.^[2][3]

If B is not a logical subset of A, there may be no clean five-Justice rule on the broader question.

Worked Example: A Dissent Is Reported as a New ERISA Rule

Dissent says:

"ERISA should be read to give DOL broad authority over rollover recommendations."

Newsletter states:

"The Supreme Court says DOL has broad rollover authority."

That reverses the legal status of the opinion.

The accurate form is:

"The dissent argued that ERISA gives DOL broader authority."

Attribution is part of legal accuracy.

Worked Example: Hughes Is Treated as a Finding of Liability

Supreme Court vacates the Seventh Circuit judgment in Hughes v. Northwestern and remands.^[6]

Article says:

"The Supreme Court found Northwestern liable for excessive fees."

Too much.

The Court rejected the categorical reasoning used below and reiterated the context-specific duty to monitor investments.^[6]

It did not conduct a trial or enter a final fiduciary-liability judgment on every allegation.

The precedent concerns the legal standard.

The case-specific application remained for the lower court.

Worked Example: DOL "Overrules" the Supreme Court

Supreme Court interprets ERISA term X.

DOL later publishes a regulation stating:

"For purposes of this regulation, X means the opposite."

Memo says:

"Agency has overruled the Court through rulemaking."

No.

The agency cannot overrule controlling Supreme Court statutory precedent.

Possible lawful routes are different:

• Congress amends ERISA
• new facts place the rule outside the old holding
• the prior case left a genuine statutory delegation for DOL to exercise
• the Supreme Court later changes its interpretation.

The source of legal change matters.

Worked Example: Certiorari Denial Is Called Affirmance

Circuit decides a DOL case.

Supreme Court denies certiorari.

Research note adds:

"affirmed by Supreme Court."

Wrong.^[11]

The correct procedural history is:

"certiorari denied."

The circuit judgment remains.

No Supreme Court merits opinion exists.

That distinction affects how the case should be described outside the circuit.

A Practical Authority Table

The table is a starting point.

It does not replace later-history research.

Precedent Review Before Changing a 401(k) Legal Summary

Before labeling a court decision controlling, verify the following.

Court

Which court issued the opinion?

Jurisdiction

Which federal courts does that court ordinarily bind?

Question

What precise federal question was presented and decided?

Judgment

Did the court:

• affirm
• reverse
• vacate
• remand
• dismiss?

Opinion composition

How many judges or Justices joined the controlling rationale?

Holding

What proposition was necessary to the judgment?

Dicta

Which broader statements were not necessary to decide the case?

Separate opinions

Did a concurrence or dissent contain language being incorrectly attributed to the Court?

Fragmentation

If no rationale had a majority, does Marks produce a genuine common denominator?

Later history

Was the decision:

• reheard en banc
• superseded
• vacated
• reversed
• limited by later Supreme Court authority?

Statutory change

Did Congress amend the relevant ERISA provision?

Remedy

What did the court actually do to the DOL rule or lower judgment?

Current implementation

What is now operative in:

• CFR text
• Federal Register notices
• DOL guidance
• enforcement statements?

Those fields prevent a legal citation from being mistaken for a current compliance instruction.

Fast Answers

What is precedent?

A prior judicial decision that supplies a legal rule relevant to later cases, with binding force depending on the issuing court, the holding and the jurisdiction.

What is stare decisis?

The doctrine under which courts adhere to controlling prior decisions subject to the rules governing when precedent may be distinguished or overruled.

Are lower federal courts bound by Supreme Court precedent?

Yes, on controlling federal-law holdings.^[1]

Can a lower court declare an old Supreme Court case implicitly overruled?

Agostini says lower courts should continue following directly controlling Supreme Court precedent and leave overruling to the Supreme Court.^[1]

Is a Fifth Circuit DOL ruling binding nationwide?

Its circuit precedent is not nationwide Supreme Court precedent merely because the underlying DOL rule is national.

Can the remedy still have nationwide consequences?

Yes. Remedial scope and precedential scope are different.

Is every sentence in a majority opinion the holding?

No.

Is dicta worthless?

No. It can be persuasive, but it is not the same as a proposition necessary to the judgment.

Is a concurrence binding precedent?

Not by itself. In a fragmented decision, it may matter to Marks analysis.^[2]

Is a dissent precedent?

No.

What does Marks do?

It looks for the narrowest grounds supporting the judgment when no single Supreme Court rationale has five votes.^[2]

Does Marks always yield a clear rule?

No. Hughes v. United States shows why fractured opinions do not always contain a workable common denominator.^[3]

Did Loper Bright erase every Chevron-era case?

No. It overruled Chevron's deference methodology while expressly preserving ordinary statutory stare decisis for prior holdings that specific agency actions were lawful.^[4]

Can DOL overrule a Supreme Court interpretation of ERISA by issuing a regulation?

No.

Can Congress change the statute after a Supreme Court statutory decision?

Yes, subject to constitutional limits.

Can DOL issue a new rule after losing a case?

Potentially, if the new rule is consistent with the controlling holding and rests on lawful authority or delegated discretion.

What did Perez establish?

It rejected the D.C. Circuit rule requiring notice and comment merely because an agency significantly changed an interpretive rule that was itself exempt from notice and comment.^[5]

Why is Perez relevant outside wage-and-hour law?

Because its holding interprets federal administrative procedure, not merely the facts of one DOL program.^[5]

What did Hughes v. Northwestern do?

It vacated the Seventh Circuit judgment and required reconsideration under ERISA's context-specific duty of prudence, including the duty to monitor plan investments.^[6]

Did Hughes establish final liability?

No. It remanded for further proceedings.^[6]

Does vacatur always mean the same thing?

No. Identify the object vacated, the reason and the remand or dismissal instruction.^[9][10][12]

Does denial of certiorari affirm the lower court?

No.^[11]

What is the safest one-sentence rule?

Before treating a DOL or 401(k) case as controlling law, identify the court, exact holding, opinion majority, later history and jurisdiction, then separately determine what remedy and agency action make that precedent operational today.

Current obligations should be verified against controlling authority in the relevant jurisdiction and current DOL materials.
