LOPER BRIGHT ENTERPRISES ET AL. v. RAIMONDO,
SECRETARY OF COMMERCE, ET AL.

CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE DISTRICT OF COLUMBIA CIRCUIT

No. 22–451. Argued January 17, 2024—Decided June 28, 2024*
The Court granted certiorari in these cases limited to the question
whether Chevron U. S. A. Inc. v. Natural Resources Defense Council,
Inc., 467 U. S. 837, should be overruled or clarified. Under the Chev-
ron doctrine, courts have sometimes been required to defer to “permis-
sible” agency interpretations of the statutes those agencies adminis-
ter—even when a reviewing court reads the statute differently. Id., at
843. In each case below, the reviewing courts applied Chevron’s frame-
work to resolve in favor of the Government challenges by petitioners
to a rule promulgated by the National Marine Fisheries Service pur-
suant to the Magnuson-Stevens Act, 16 U. S. C. §1801 et seq., which
incorporates the Administrative Procedure Act (APA), 5 U. S. C. §551
et seq.
Held: The Administrative Procedure Act requires courts to exercise their
independent judgment in deciding whether an agency has acted within
its statutory authority, and courts may not defer to an agency inter-
pretation of the law simply because a statute is ambiguous; Chevron is
overruled. Pp. 7–35.
(a) Article III of the Constitution assigns to the Federal Judiciary
the responsibility and power to adjudicate “Cases” and “Controver-
sies”—concrete disputes with consequences for the parties involved.
The Framers appreciated that the laws judges would necessarily apply
in resolving those disputes would not always be clear, but envisioned

Syllabus

that the final “interpretation of the laws” would be “the proper and
peculiar province of the courts.” The Federalist No. 78, p. 525 (A. Ham-
ilton). As Chief Justice Marshall declared in the foundational decision
of Marbury v. Madison, “[i]t is emphatically the province and duty of
the judicial department to say what the law is.” 1 Cranch 137, 177. In
the decades following Marbury, when the meaning of a statute was at
issue, the judicial role was to “interpret the act of Congress, in order to
ascertain the rights of the parties.” Decatur v. Paulding, 14 Pet. 497,
515.
The Court recognized from the outset, though, that exercising inde-
pendent judgment often included according due respect to Executive
Branch interpretations of federal statutes. Such respect was thought
especially warranted when an Executive Branch interpretation was is-
sued roughly contemporaneously with enactment of the statute and
remained consistent over time. The Court also gave “the most respect-
ful consideration” to Executive Branch interpretations simply because
“[t]he officers concerned [were] usually able men, and masters of the
subject,” who may well have drafted the laws at issue. United States
v. Moore, 95 U. S. 760, 763. “Respect,” though, was just that. The
views of the Executive Branch could inform the judgment of the Judi-
ciary, but did not supersede it. “[I]n cases where [a court’s] own judg-
ment . . . differ[ed] from that of other high functionaries,” the court was
“not at liberty to surrender, or to waive it.” United States v. Dickson,
15 Pet. 141, 162.
During the “rapid expansion of the administrative process” that took
place during the New Deal era, United States v. Morton Salt Co., 338
U. S. 632, 644, the Court often treated agency determinations of fact
as binding on the courts, provided that there was “evidence to support
the findings,” St. Joseph Stock Yards Co. v. United States, 298 U. S.
38, 51. But the Court did not extend similar deference to agency reso-
lutions of questions of law. “The interpretation of the meaning of stat-
utes, as applied to justiciable controversies,” remained “exclusively a
judicial function.” United States v. American Trucking Assns., Inc.,
310 U. S. 534, 544. The Court also continued to note that the informed
judgment of the Executive Branch could be entitled to “great weight.”
Id., at 549. “The weight of such a judgment in a particular case,” the
Court observed, would “depend upon the thoroughness evident in its
consideration, the validity of its reasoning, its consistency with earlier
and later pronouncements, and all those factors which give it power to
persuade, if lacking power to control.” Skidmore v. Swift & Co., 323
U. S. 134, 140.
Occasionally during this period, the Court applied deferential re-
view after concluding that a particular statute empowered an agency
to decide how a broad statutory term applied to specific facts found by

Syllabus

the agency. See Gray v. Powell, 314 U. S. 402; NLRB v. Hearst Publi-
cations, Inc., 322 U. S. 111. But such deferential review, which the
Court was far from consistent in applying, was cabined to factbound
determinations. And the Court did not purport to refashion the
longstanding judicial approach to questions of law. It instead pro-
claimed that “[u]ndoubtedly questions of statutory interpretation . . .
are for the courts to resolve, giving appropriate weight to the judgment
of those whose special duty is to administer the questioned statute.”
Id., at 130–131. Nothing in the New Deal era or before it thus resem-
bled the deference rule the Court would begin applying decades later
to all varieties of agency interpretations of statutes under Chevron.
Pp. 7–13.
(b) Congress in 1946 enacted the APA “as a check upon administra-
tors whose zeal might otherwise have carried them to excesses not con-
templated in legislation creating their offices.” Morton Salt, 338 U. S.,
at 644. The APA prescribes procedures for agency action and deline-
ates the basic contours of judicial review of such action. And it codifies
for agency cases the unremarkable, yet elemental proposition reflected
by judicial practice dating back to Marbury: that courts decide legal
questions by applying their own judgment. As relevant here, the APA
specifies that courts, not agencies, will decide “all relevant questions
of law” arising on review of agency action, 5 U. S. C. §706 (emphasis
added)—even those involving ambiguous laws. It prescribes no defer-
ential standard for courts to employ in answering those legal ques-
tions, despite mandating deferential judicial review of agency policy-
making and factfinding. See §§706(2)(A), (E). And by directing courts
to “interpret constitutional and statutory provisions” without differen-
tiating between the two, §706, it makes clear that agency interpreta-
tions of statutes—like agency interpretations of the Constitution—are
not entitled to deference. The APA’s history and the contemporaneous
views of various respected commentators underscore the plain mean-
ing of its text.
Courts exercising independent judgment in determining the mean-
ing of statutory provisions, consistent with the APA, may—as they
have from the start—seek aid from the interpretations of those respon-
sible for implementing particular statutes. See Skidmore, 323 U. S.,
at 140. And when the best reading of a statute is that it delegates
discretionary authority to an agency, the role of the reviewing court
under the APA is, as always, to independently interpret the statute
and effectuate the will of Congress subject to constitutional limits. The
court fulfills that role by recognizing constitutional delegations, fixing
the boundaries of the delegated authority, and ensuring the agency
has engaged in “ ‘reasoned decisionmaking’ ” within those boundaries.

Syllabus

Service, Inc. v. NLRB, 522 U. S. 359, 374). By doing so, a court upholds
the traditional conception of the judicial function that the APA adopts.
Pp. 13–18.
(c) The deference that Chevron requires of courts reviewing agency
action cannot be squared with the APA. Pp. 18–29.
(1) Chevron, decided in 1984 by a bare quorum of six Justices, trig-
gered a marked departure from the traditional judicial approach of in-
dependently examining each statute to determine its meaning. The
question in the case was whether an Environmental Protection Agency
(EPA) regulation was consistent with the term “stationary source” as
used in the Clean Air Act. 467 U. S., at 840. To answer that question,
the Court articulated and employed a now familiar two-step approach
broadly applicable to review of agency action. The first step was to
discern “whether Congress ha[d] directly spoken to the precise ques-
tion at issue.” Id., at 842. The Court explained that “[i]f the intent of
Congress is clear, that is the end of the matter,” ibid., and courts were
therefore to “reject administrative constructions which are contrary to
clear congressional intent,” id., at 843, n. 9. But in a case in which “the
statute [was] silent or ambiguous with respect to the specific issue” at
hand, a reviewing court could not “simply impose its own construction
on the statute, as would be necessary in the absence of an administra-
tive interpretation.” Id., at 843 (footnote omitted). Instead, at Chev-
ron’s second step, a court had to defer to the agency if it had offered “a
permissible construction of the statute,” ibid., even if not “the reading
the court would have reached if the question initially had arisen in a
judicial proceeding,” ibid., n. 11. Employing this new test, the Court
concluded that Congress had not addressed the question at issue with
the necessary “level of specificity” and that EPA’s interpretation was
“entitled to deference.” Id., at 865.
Although the Court did not at first treat Chevron as the watershed
decision it was fated to become, the Court and the courts of appeals
were soon routinely invoking its framework as the governing standard
in cases involving statutory questions of agency authority. The Court
eventually decided that Chevron rested on “a presumption that Con-
gress, when it left ambiguity in a statute meant for implementation by
an agency, understood that the ambiguity would be resolved, first and
foremost, by the agency, and desired the agency (rather than the
courts) to possess whatever degree of discretion the ambiguity allows.”
Smiley v. Citibank (South Dakota), N. A., 517 U. S. 735, 740–741. Pp.
18–20.
(2) Neither Chevron nor any subsequent decision of the Court at-
tempted to reconcile its framework with the APA. Chevron defies the
command of the APA that “the reviewing court”—not the agency whose
Cite as: 603 U. S. ____ (2024) 5

Syllabus

action it reviews—is to “decide all relevant questions of law” and “in-
terpret . . . statutory provisions.” §706 (emphasis added). It requires
a court to ignore, not follow, “the reading the court would have
reached” had it exercised its independent judgment as required by the
APA. Chevron, 467 U. S., at 843, n. 11. Chevron insists on more than
the “respect” historically given to Executive Branch interpretations; it
demands that courts mechanically afford binding deference to agency
interpretations, including those that have been inconsistent over time,
see id., at 863, and even when a pre-existing judicial precedent holds
that an ambiguous statute means something else, National Cable &
Telecommunications Assn. v. Brand X Internet Services, 545 U. S. 967,
982. That regime is the antithesis of the time honored approach the
APA prescribes.
Chevron cannot be reconciled with the APA by presuming that stat-
utory ambiguities are implicit delegations to agencies. That presump-
tion does not approximate reality. A statutory ambiguity does not nec-
essarily reflect a congressional intent that an agency, as opposed to a
court, resolve the resulting interpretive question. Many or perhaps
most statutory ambiguities may be unintentional. And when courts
confront statutory ambiguities in cases that do not involve agency in-
terpretations or delegations of authority, they are not somehow re-
lieved of their obligation to independently interpret the statutes. In-
stead of declaring a particular party’s reading “permissible” in such a
case, courts use every tool at their disposal to determine the best read-
ing of the statute and resolve the ambiguity. But in an agency case as
in any other, there is a best reading all the same—“the reading the
court would have reached” if no agency were involved. Chevron, 467
U. S., at 843, n. 11. It therefore makes no sense to speak of a “permis-
sible” interpretation that is not the one the court, after applying all
relevant interpretive tools, concludes is best.
Perhaps most fundamentally, Chevron’s presumption is misguided
because agencies have no special competence in resolving statutory
ambiguities. Courts do. The Framers anticipated that courts would
often confront statutory ambiguities and expected that courts would
resolve them by exercising independent legal judgment. Chevron
gravely erred in concluding that the inquiry is fundamentally different
just because an administrative interpretation is in play. The very
point of the traditional tools of statutory construction is to resolve stat-
utory ambiguities. That is no less true when the ambiguity is about
the scope of an agency’s own power—perhaps the occasion on which
abdication in favor of the agency is least appropriate. Pp. 21–23.
(3) The Government responds that Congress must generally in-
tend for agencies to resolve statutory ambiguities because agencies
have subject matter expertise regarding the statutes they administer;
6 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Syllabus

because deferring to agencies purportedly promotes the uniform con-
struction of federal law; and because resolving statutory ambiguities
can involve policymaking best left to political actors, rather than
courts. See Brief for Respondents in No. 22–1219, pp. 16–19. But none
of these considerations justifies Chevron’s sweeping presumption of
congressional intent.
As the Court recently noted, interpretive issues arising in connec-
tion with a regulatory scheme “may fall more naturally into a judge’s
bailiwick” than an agency’s. Kisor v. Wilkie, 588 U. S. 558, 578. Under
Chevron’s broad rule of deference, though, ambiguities of all stripes
trigger deference, even in cases having little to do with an agency’s
technical subject matter expertise. And even when an ambiguity hap-
pens to implicate a technical matter, it does not follow that Congress
has taken the power to authoritatively interpret the statute from the
courts and given it to the agency. Congress expects courts to handle
technical statutory questions, and courts did so without issue in
agency cases before Chevron. After all, in an agency case in particular,
the reviewing court will go about its task with the agency’s “body of
experience and informed judgment,” among other information, at its
disposal. Skidmore, 323 U. S., at 140. An agency’s interpretation of a
statute “cannot bind a court,” but may be especially informative “to the
extent it rests on factual premises within [the agency’s] expertise.” Bu-
reau of Alcohol, Tobacco and Firearms v. FLRA, 464 U. S. 89, 98, n. 8.
Delegating ultimate interpretive authority to agencies is simply not
necessary to ensure that the resolution of statutory ambiguities is well
informed by subject matter expertise.
Nor does a desire for the uniform construction of federal law justify
Chevron. It is unclear how much the Chevron doctrine as a whole ac-
tually promotes such uniformity, and in any event, we see no reason to
presume that Congress prefers uniformity for uniformity’s sake over
the correct interpretation of the laws it enacts.
Finally, the view that interpretation of ambiguous statutory provi-
sions amounts to policymaking suited for political actors rather than
courts is especially mistaken because it rests on a profound misconcep-
tion of the judicial role. Resolution of statutory ambiguities involves
legal interpretation, and that task does not suddenly become policy-
making just because a court has an “agency to fall back on.” Kisor, 588
U. S., at 575. Courts interpret statutes, no matter the context, based
on the traditional tools of statutory construction, not individual policy
preferences. To stay out of discretionary policymaking left to the po-
litical branches, judges need only fulfill their obligations under the
APA to independently identify and respect such delegations of author-
ity, police the outer statutory boundaries of those delegations, and en-
sure that agencies exercise their discretion consistent with the APA.
Cite as: 603 U. S. ____ (2024) 7

Syllabus

By forcing courts to instead pretend that ambiguities are necessarily
delegations, Chevron prevents judges from judging. Pp. 23–26.
(4) Because Chevron’s justifying presumption is, as Members of
the Court have often recognized, a fiction, the Court has spent the bet-
ter part of four decades imposing one limitation on Chevron after an-
other. Confronted with the byzantine set of preconditions and excep-
tions that has resulted, some courts have simply bypassed Chevron or
failed to heed its various steps and nuances. The Court, for its part,
has not deferred to an agency interpretation under Chevron since
2016. But because Chevron remains on the books, litigants must con-
tinue to wrestle with it, and lower courts—bound by even the Court’s
crumbling precedents—understandably continue to apply it. At best,
Chevron has been a distraction from the question that matters: Does
the statute authorize the challenged agency action? And at worst, it
has required courts to violate the APA by yielding to an agency the
express responsibility, vested in “the reviewing court,” to “decide all
relevant questions of law” and “interpret . . . statutory provisions.”
§706 (emphasis added). Pp. 26–29.
(d) Stare decisis, the doctrine governing judicial adherence to prece-
dent, does not require the Court to persist in the Chevron project. The
stare decisis considerations most relevant here—“the quality of [the
precedent’s] reasoning, the workability of the rule it established, . . .
and reliance on the decision,” Knick v. Township of Scott, 588 U. S.
180, 203 (quoting Janus v. State, County, and Municipal Employees,
585 U. S. 878, 917)—all weigh in favor of letting Chevron go.
Chevron has proved to be fundamentally misguided. It reshaped ju-
dicial review of agency action without grappling with the APA, the
statute that lays out how such review works. And its flaws were ap-
parent from the start, prompting the Court to revise its foundations
and continually limit its application.
Experience has also shown that Chevron is unworkable. The defin-
ing feature of its framework is the identification of statutory ambigu-
ity, but the concept of ambiguity has always evaded meaningful defi-
nition. Such an impressionistic and malleable concept “cannot stand
as an every-day test for allocating” interpretive authority between
courts and agencies. Swift & Co. v. Wickham, 382 U. S. 111, 125. The
Court has also been forced to clarify the doctrine again and again, only
adding to Chevron’s unworkability, and the doctrine continues to
spawn difficult threshold questions that promise to further complicate
the inquiry should Chevron be retained. And its continuing import is
far from clear, as courts have often declined to engage with the doc-
trine, saying it makes no difference.
Nor has Chevron fostered meaningful reliance. Given the Court’s
constant tinkering with and eventual turn away from Chevron, it is
8 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Syllabus

hard to see how anyone could reasonably expect a court to rely on Chev-
ron in any particular case or expect it to produce readily foreseeable
outcomes. And rather than safeguarding reliance interests, Chevron
affirmatively destroys them by allowing agencies to change course
even when Congress has given them no power to do so.
The only way to “ensure that the law will not merely change errati-
cally, but will develop in a principled and intelligible fashion,” Vasquez
v. Hillery, 474 U. S. 254, 265, is for the Court to leave Chevron behind.
By overruling Chevron, though, the Court does not call into question
prior cases that relied on the Chevron framework. The holdings of
those cases that specific agency actions are lawful—including the
Clean Air Act holding of Chevron itself—are still subject to statutory
stare decisis despite the Court’s change in interpretive methodology.
See CBOCS West, Inc. v. Humphries, 553 U. S. 442, 457. Mere reliance
on Chevron cannot constitute a “ ‘special justification’ ” for overruling
such a holding. Halliburton Co. v. Erica P. John Fund, Inc., 573 U. S.

CHIEF JUSTICE ROBERTS delivered the opinion of the
Court.
Since our decision in Chevron U. S. A. Inc. v. Natural Re-
sources Defense Council, Inc., 467 U. S. 837 (1984), we have
sometimes required courts to defer to “permissible” agency
interpretations of the statutes those agencies administer—
even when a reviewing court reads the statute differently.
In these cases we consider whether that doctrine should be
overruled.
I
Our Chevron doctrine requires courts to use a two-step

Opinion of the Court

framework to interpret statutes administered by federal
agencies. After determining that a case satisfies the vari-
ous preconditions we have set for Chevron to apply, a re-
viewing court must first assess “whether Congress has di-
rectly spoken to the precise question at issue.” Id., at 842.
If, and only if, congressional intent is “clear,” that is the end
of the inquiry. Ibid. But if the court determines that “the
statute is silent or ambiguous with respect to the specific
issue” at hand, the court must, at Chevron’s second step,
defer to the agency’s interpretation if it “is based on a per-
missible construction of the statute.” Id., at 843. The re-
viewing courts in each of the cases before us applied Chev-
ron’s framework to resolve in favor of the Government
challenges to the same agency rule.
A
Before 1976, unregulated foreign vessels dominated fish-
ing in the international waters off the U. S. coast, which be-
gan just 12 nautical miles offshore. See, e.g., S. Rep.
No. 94–459, pp. 2–3 (1975). Recognizing the resultant over-
fishing and the need for sound management of fishery re-
sources, Congress enacted the Magnuson-Stevens Fishery
Conservation and Management Act (MSA). See 90 Stat.
331 (codified as amended at 16 U. S. C. §1801 et seq.). The
MSA and subsequent amendments extended the jurisdic-
tion of the United States to 200 nautical miles beyond the
U. S. territorial sea and claimed “exclusive fishery manage-
ment authority over all fish” within that area, known as the
“exclusive economic zone.” §1811(a); see Presidential Proc-
lamation No. 5030, 3 CFR 22 (1983 Comp.); §§101, 102, 90
Stat. 336. The National Marine Fisheries Service (NMFS)
administers the MSA under a delegation from the Secretary
of Commerce.
The MSA established eight regional fishery management
councils composed of representatives from the coastal
States, fishery stakeholders, and NMFS. See 16 U. S. C.
Cite as: 603 U. S. ____ (2024) 3

Opinion of the Court

§§1852(a), (b). The councils develop fishery management
plans, which NMFS approves and promulgates as final reg-
ulations. See §§1852(h), 1854(a). In service of the statute’s
fishery conservation and management goals, see §1851(a),
the MSA requires that certain provisions—such as “a mech-
anism for specifying annual catch limits . . . at a level such
that overfishing does not occur,” §1853(a)(15)—be included
in these plans, see §1853(a). The plans may also include
additional discretionary provisions. See §1853(b). For ex-
ample, plans may “prohibit, limit, condition, or require the
use of specified types and quantities of fishing gear, fishing
vessels, or equipment,” §1853(b)(4); “reserve a portion of the
allowable biological catch of the fishery for use in scientific
research,” §1853(b)(11); and “prescribe such other
measures, requirements, or conditions and restrictions as
are determined to be necessary and appropriate for the con-
servation and management of the fishery,” §1853(b)(14).
Relevant here, a plan may also require that “one or more
observers be carried on board” domestic vessels “for the pur-
pose of collecting data necessary for the conservation and
management of the fishery.” §1853(b)(8). The MSA speci-
fies three groups that must cover costs associated with ob-
servers: (1) foreign fishing vessels operating within the ex-
clusive economic zone (which must carry observers), see
§§1821(h)(1)(A), (h)(4), (h)(6); (2) vessels participating in
certain limited access privilege programs, which impose
quotas permitting fishermen to harvest only specific quan-
tities of a fishery’s total allowable catch, see §§1802(26),
1853a(c)(1)(H), (e)(2), 1854(d)(2); and (3) vessels within the
jurisdiction of the North Pacific Council, where many of the
largest and most successful commercial fishing enterprises
in the Nation operate, see §1862(a). In the latter two cases,
the MSA expressly caps the relevant fees at two or three
percent of the value of fish harvested on the vessels. See
§§1854(d)(2)(B), 1862(b)(2)(E). And in general, it author-
4 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

izes the Secretary to impose “sanctions” when “any pay-
ment required for observer services provided to or con-
tracted by an owner or operator . . . has not been paid.”
§1858(g)(1)(D).
The MSA does not contain similar terms addressing
whether Atlantic herring fishermen may be required to
bear costs associated with any observers a plan may man-
date. And at one point, NMFS fully funded the observer
coverage the New England Fishery Management Council
required in its plan for the Atlantic herring fishery. See 79
Fed. Reg. 8792 (2014). In 2013, however, the council pro-
posed amending its fishery management plans to empower
it to require fishermen to pay for observers if federal fund-
ing became unavailable. Several years later, NMFS prom-
ulgated a rule approving the amendment. See 85 Fed. Reg.
7414 (2020).
With respect to the Atlantic herring fishery, the Rule cre-
ated an industry funded program that aims to ensure ob-
server coverage on 50 percent of trips undertaken by vessels
with certain types of permits. Under that program, vessel
representatives must “declare into” a fishery before begin-
ning a trip by notifying NMFS of the trip and announcing
the species the vessel intends to harvest. If NMFS deter-
mines that an observer is required, but declines to assign a
Government-paid one, the vessel must contract with and
pay for a Government-certified third-party observer.
NMFS estimated that the cost of such an observer would be
up to $710 per day, reducing annual returns to the vessel
owner by up to 20 percent. See id., at 7417–7418.

Petitioners Loper Bright Enterprises, Inc., H&L Axels-

Opinion of the Court

the Administrative Procedure Act (APA), 5 U. S. C. §551
et seq. In relevant part, they argued that the MSA does not
authorize NMFS to mandate that they pay for observers re-
quired by a fishery management plan. The District Court
granted summary judgment to the Government. It con-
cluded that the MSA authorized the Rule, but noted that
even if these petitioners’ “arguments were enough to raise
an ambiguity in the statutory text,” deference to the
agency’s interpretation would be warranted under Chevron.
544 F. Supp. 3d 82, 107 (DC 2021); see id., at 103–107.
A divided panel of the D. C. Circuit affirmed. See 45
F. 4th 359 (2022). The majority addressed various provi-
sions of the MSA and concluded that it was not “wholly un-
ambiguous” whether NMFS may require Atlantic herring
fishermen to pay for observers. Id., at 366. Because there
remained “some question” as to Congress’s intent, id., at
369, the court proceeded to Chevron’s second step and de-
ferred to the agency’s interpretation as a “reasonable” con-
struction of the MSA, 45 F. 4th, at 370. In dissent, Judge
Walker concluded that Congress’s silence on industry
funded observers for the Atlantic herring fishery—coupled
with the express provision for such observers in other fish-
eries and on foreign vessels—unambiguously indicated that
NMFS lacked the authority to “require [Atlantic herring]
fishermen to pay the wages of at-sea monitors.” Id., at 375.
C
Petitioners Relentless Inc., Huntress Inc., and Seafreeze
Fleet LLC own two vessels that operate in the Atlantic her-
ring fishery: the F/V Relentless and the F/V Persistence.1
These vessels use small-mesh bottom-trawl gear and can
freeze fish at sea, so they can catch more species of fish and
take longer trips than other vessels (about 10 to 14 days, as

Opinion of the Court

opposed to the more typical 2 to 4). As a result, they gener-
ally declare into multiple fisheries per trip so they can catch
whatever the ocean offers up. If the vessels declare into the
Atlantic herring fishery for a particular trip, they must
carry an observer for that trip if NMFS selects the trip for
coverage, even if they end up harvesting fewer herring than
other vessels—or no herring at all.
This set of petitioners, like those in the D. C. Circuit case,
filed a suit challenging the Rule as unauthorized by the
MSA. The District Court, like the D. C. Circuit, deferred to
NMFS’s contrary interpretation under Chevron and thus
granted summary judgment to the Government. See 561
F. Supp. 3d 226, 234–238 (RI 2021).
The First Circuit affirmed. See 62 F. 4th 621 (2023). It
relied on a “default norm” that regulated entities must bear
compliance costs, as well as the MSA’s sanctions provision,
Section 1858(g)(1)(D). See id., at 629–631. And it rejected
petitioners’ argument that the express statutory authoriza-
tion of three industry funding programs demonstrated that
NMFS lacked the broad implicit authority it asserted to im-
pose such a program for the Atlantic herring fishery. See
id., at 631–633. The court ultimately concluded that the
“[a]gency’s interpretation of its authority to require at-sea
monitors who are paid for by owners of regulated vessels
does not ‘exceed[ ] the bounds of the permissible.’ ” Id., at
633–634 (quoting Barnhart v. Walton, 535 U. S. 212, 218
(2002); alteration in original). In reaching that conclusion,
the First Circuit stated that it was applying Chevron’s two-
step framework. 62 F. 4th, at 628. But it did not explain
which aspects of its analysis were relevant to which of
Chevron’s two steps. Similarly, it declined to decide
whether the result was “a product of Chevron step one or
step two.” Id., at 634.
We granted certiorari in both cases, limited to the ques-
tion whether Chevron should be overruled or clarified. See

A
Article III of the Constitution assigns to the Federal Ju-
diciary the responsibility and power to adjudicate “Cases”
and “Controversies”—concrete disputes with consequences
for the parties involved. The Framers appreciated that the
laws judges would necessarily apply in resolving those dis-
putes would not always be clear. Cognizant of the limits of
human language and foresight, they anticipated that “[a]ll
new laws, though penned with the greatest technical skill,
and passed on the fullest and most mature deliberation,”
would be “more or less obscure and equivocal, until their
meaning” was settled “by a series of particular discussions
and adjudications.” The Federalist No. 37, p. 236 (J. Cooke
ed. 1961) (J. Madison).
The Framers also envisioned that the final “interpreta-
tion of the laws” would be “the proper and peculiar province
of the courts.” Id., No. 78, at 525 (A. Hamilton). Unlike the
political branches, the courts would by design exercise “nei-
ther Force nor Will, but merely judgment.” Id., at 523. To
ensure the “steady, upright and impartial administration of
the laws,” the Framers structured the Constitution to allow
judges to exercise that judgment independent of influence
from the political branches. Id., at 522; see id., at 522–524;
Stern v. Marshall, 564 U. S. 462, 484 (2011).
This Court embraced the Framers’ understanding of the
judicial function early on. In the foundational decision of
Marbury v. Madison, Chief Justice Marshall famously de-
clared that “[i]t is emphatically the province and duty of the
judicial department to say what the law is.” 1 Cranch 137,

those questions and thus do not reach them.
8 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

177 (1803). And in the following decades, the Court under-
stood “interpret[ing] the laws, in the last resort,” to be a
“solemn duty” of the Judiciary. United States v. Dickson,
15 Pet. 141, 162 (1841) (Story, J., for the Court). When the
meaning of a statute was at issue, the judicial role was to
“interpret the act of Congress, in order to ascertain the
rights of the parties.” Decatur v. Paulding, 14 Pet. 497, 515
(1840).
The Court also recognized from the outset, though, that
exercising independent judgment often included according
due respect to Executive Branch interpretations of federal
statutes. For example, in Edwards’ Lessee v. Darby, 12
Wheat. 206 (1827), the Court explained that “[i]n the con-
struction of a doubtful and ambiguous law, the contempo-
raneous construction of those who were called upon to act
under the law, and were appointed to carry its provisions
into effect, is entitled to very great respect.” Id., at 210; see
also United States v. Vowell, 5 Cranch 368, 372 (1809) (Mar-
shall, C. J., for the Court).
Such respect was thought especially warranted when an
Executive Branch interpretation was issued roughly con-
temporaneously with enactment of the statute and re-
mained consistent over time. See Dickson, 15 Pet., at 161;
United States v. Alabama Great Southern R. Co., 142 U. S.
615, 621 (1892); National Lead Co. v. United States, 252
U. S. 140, 145–146 (1920). That is because “the longstand-
ing ‘practice of the government’ ”—like any other interpre-
tive aid—“can inform [a court’s] determination of ‘what the
law is.’ ” NLRB v. Noel Canning, 573 U. S. 513, 525 (2014)
(first quoting McCulloch v. Maryland, 4 Wheat. 316, 401
(1819); then quoting Marbury, 1 Cranch, at 177). The Court
also gave “the most respectful consideration” to Executive
Branch interpretations simply because “[t]he officers con-
cerned [were] usually able men, and masters of the subject,”
who were “[n]ot unfrequently . . . the draftsmen of the laws
they [were] afterwards called upon to interpret.” United

Opinion of the Court

States v. Moore, 95 U. S. 760, 763 (1878); see also Jacobs v.
Prichard, 223 U. S. 200, 214 (1912).
“Respect,” though, was just that. The views of the Exec-
utive Branch could inform the judgment of the Judiciary,
but did not supersede it. Whatever respect an Executive
Branch interpretation was due, a judge “certainly would not
be bound to adopt the construction given by the head of a
department.” Decatur, 14 Pet., at 515; see also Burnet v.
Chicago Portrait Co., 285 U. S. 1, 16 (1932). Otherwise, ju-
dicial judgment would not be independent at all. As Justice
Story put it, “in cases where [a court’s] own judgment . . .
differ[ed] from that of other high functionaries,” the court
was “not at liberty to surrender, or to waive it.” Dickson,
15 Pet., at 162.
B
The New Deal ushered in a “rapid expansion of the ad-
ministrative process.” United States v. Morton Salt Co., 338
U. S. 632, 644 (1950). But as new agencies with new powers
proliferated, the Court continued to adhere to the tradi-
tional understanding that questions of law were for courts
to decide, exercising independent judgment.
During this period, the Court often treated agency deter-
minations of fact as binding on the courts, provided that
there was “evidence to support the findings.” St. Joseph
Stock Yards Co. v. United States, 298 U. S. 38, 51 (1936).
“When the legislature itself acts within the broad field of
legislative discretion,” the Court reasoned, “its determina-
tions are conclusive.” Ibid. Congress could therefore “ap-
point[ ] an agent to act within that sphere of legislative au-
thority” and “endow the agent with power to make findings
of fact which are conclusive, provided the requirements of
due process which are specially applicable to such an
agency are met, as in according a fair hearing and acting
upon evidence and not arbitrarily.” Ibid. (emphasis added).
But the Court did not extend similar deference to agency

Opinion of the Court

resolutions of questions of law. It instead made clear, re-
peatedly, that “[t]he interpretation of the meaning of stat-
utes, as applied to justiciable controversies,” was “exclu-
sively a judicial function.” United States v. American
Trucking Assns., Inc., 310 U. S. 534, 544 (1940); see also
Social Security Bd. v. Nierotko, 327 U. S. 358, 369 (1946);
Medo Photo Supply Corp. v. NLRB, 321 U. S. 678, 681–682,
n. 1 (1944). The Court understood, in the words of Justice
Brandeis, that “[t]he supremacy of law demands that there
shall be opportunity to have some court decide whether an
erroneous rule of law was applied.” St. Joseph Stock Yards,
298 U. S., at 84 (concurring opinion). It also continued to
note, as it long had, that the informed judgment of the Ex-
ecutive Branch—especially in the form of an interpretation
issued contemporaneously with the enactment of the stat-
ute—could be entitled to “great weight.” American Truck-
ing Assns., 310 U. S., at 549.
Perhaps most notably along those lines, in Skidmore v.
Swift & Co., 323 U. S. 134 (1944), the Court explained that
the “interpretations and opinions” of the relevant agency,
“made in pursuance of official duty” and “based upon . . .
specialized experience,” “constitute[d] a body of experience
and informed judgment to which courts and litigants [could]
properly resort for guidance,” even on legal questions. Id.,
at 139–140. “The weight of such a judgment in a particular
case,” the Court observed, would “depend upon the thor-
oughness evident in its consideration, the validity of its rea-
soning, its consistency with earlier and later pronounce-
ments, and all those factors which give it power to
persuade, if lacking power to control.” Id., at 140.
On occasion, to be sure, the Court applied deferential re-
view upon concluding that a particular statute empowered
an agency to decide how a broad statutory term applied to
specific facts found by the agency. For example, in Gray v.
Powell, 314 U. S. 402 (1941), the Court deferred to an ad-
ministrative conclusion that a coal-burning railroad that
Cite as: 603 U. S. ____ (2024) 11

Opinion of the Court

had arrangements with several coal mines was not a coal
“producer” under the Bituminous Coal Act of 1937. Con-
gress had “specifically” granted the agency the authority to
make that determination. Id., at 411. The Court thus rea-
soned that “[w]here, as here, a determination has been left
to an administrative body, this delegation will be respected
and the administrative conclusion left untouched” so long
as the agency’s decision constituted “a sensible exercise of
judgment.” Id., at 412–413. Similarly, in NLRB v. Hearst
Publications, Inc., 322 U. S. 111 (1944), the Court deferred
to the determination of the National Labor Relations Board
that newsboys were “employee[s]” within the meaning of
the National Labor Relations Act. The Act had, in the
Court’s judgment, “assigned primarily” to the Board the
task of marking a “definitive limitation around the term
‘employee.’ ” Id., at 130. The Court accordingly viewed its
own role as “limited” to assessing whether the Board’s de-
termination had a “ ‘warrant in the record’ and a reasonable
basis in law.” Id., at 131.
Such deferential review, though, was cabined to fact-
bound determinations like those at issue in Gray and
Hearst. Neither Gray nor Hearst purported to refashion the
longstanding judicial approach to questions of law. In
Gray, after deferring to the agency’s determination that a
particular entity was not a “producer” of coal, the Court
went on to discern, based on its own reading of the text,
whether another statutory term—“other disposal” of coal—
encompassed a transaction lacking a transfer of title. See
314 U. S., at 416–417. The Court evidently perceived no
basis for deference to the agency with respect to that pure
legal question. And in Hearst, the Court proclaimed that
“[u]ndoubtedly questions of statutory interpretation . . . are
for the courts to resolve, giving appropriate weight to the
judgment of those whose special duty is to administer the
questioned statute.” 322 U. S., at 130–131. At least with
12 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

respect to questions it regarded as involving “statutory in-
terpretation,” the Court thus did not disturb the traditional
rule. It merely thought that a different approach should
apply where application of a statutory term was sufficiently
intertwined with the agency’s factfinding.
In any event, the Court was far from consistent in review-
ing deferentially even such factbound statutory determina-
tions. Often the Court simply interpreted and applied the
statute before it. See K. Davis, Administrative Law §248,
p. 893 (1951) (“The one statement that can be made with
confidence about applicability of the doctrine of Gray v.
Powell is that sometimes the Supreme Court applies it and
sometimes it does not.”); B. Schwartz, Gray vs. Powell and
the Scope of Review, 54 Mich. L. Rev. 1, 68 (1955) (noting
an “embarrassingly large number of Supreme Court deci-
sions that do not adhere to the doctrine of Gray v. Powell”).
In one illustrative example, the Court rejected the U. S.
Price Administrator’s determination that a particular
warehouse was a “public utility” entitled to an exemption
from the Administrator’s General Maximum Price Regula-
tion. Despite the striking resemblance of that administra-
tive determination to those that triggered deference in Gray
and Hearst, the Court declined to “accept the Administra-
tor’s view in deference to administrative construction.” Da-
vies Warehouse Co. v. Bowles, 321 U. S. 144, 156 (1944).
The Administrator’s view, the Court explained, had “hardly
seasoned or broadened into a settled administrative prac-
tice,” and thus did not “overweigh the considerations” the
Court had “set forth as to the proper construction of the
statute.” Ibid.
Nothing in the New Deal era or before it thus resembled
the deference rule the Court would begin applying decades
later to all varieties of agency interpretations of statutes.
Instead, just five years after Gray and two after Hearst,
Congress codified the opposite rule: the traditional under-
standing that courts must “decide all relevant questions of

Congress in 1946 enacted the APA “as a check upon ad-
ministrators whose zeal might otherwise have carried them
to excesses not contemplated in legislation creating their
offices.” Morton Salt, 338 U. S., at 644. It was the culmi-
nation of a “comprehensive rethinking of the place of ad-
ministrative agencies in a regime of separate and divided
powers.” Bowen v. Michigan Academy of Family Physi-
cians, 476 U. S. 667, 670–671 (1986).
In addition to prescribing procedures for agency action,
the APA delineates the basic contours of judicial review of
such action. As relevant here, Section 706 directs that “[t]o

3 The dissent plucks out Gray, Hearst, and—to “gild the lily,” in its tell-

ing—three more 1940s decisions, claiming they reflect the relevant his-
torical tradition of judicial review. Post, at 21–22, and n. 6 (opinion of
KAGAN, J.). But it has no substantial response to the fact that Gray and
Hearst themselves endorsed, implicitly in one case and explicitly in the
next, the traditional rule that “questions of statutory interpretation . . .
are for the courts to resolve, giving appropriate weight”—not outright
deference—“to the judgment of those whose special duty is to administer
the questioned statute.” Hearst, 322 U. S., at 130–131. And it fails to
recognize the deep roots that this rule has in our Nation’s judicial tradi-
tion, to the limited extent it engages with that tradition at all. See post,
at 20–21, n. 5. Instead, like the Government, it strains to equate the
“respect” or “weight” traditionally afforded to Executive Branch interpre-
tations with binding deference. See ibid.; Brief for Respondents in No.
22–1219, pp. 21–24. That supposed equivalence is a fiction. The dis-
sent’s cases establish that a “contemporaneous construction” shared by
“not only . . . the courts” but also “the departments” could be “control-
ling,” Schell’s Executors v. Fauché, 138 U. S. 562, 572 (1891) (emphasis
added), and that courts might “lean in favor” of a “contemporaneous” and
“continued” construction of the Executive Branch as strong evidence of a
statute’s meaning, United States v. Alabama Great Southern R. Co., 142
U. S. 615, 621 (1892). They do not establish that Executive Branch in-
terpretations of ambiguous statutes—no matter how inconsistent, late
breaking, or flawed—always bound the courts. In reality, a judge was
never “bound to adopt the construction given by the head of a depart-
ment.” Decatur v. Paulding, 14 Pet. 497, 515 (1840).
14 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

the extent necessary to decision and when presented, the
reviewing court shall decide all relevant questions of law,
interpret constitutional and statutory provisions, and de-
termine the meaning or applicability of the terms of an
agency action.” 5 U. S. C. §706. It further requires courts
to “hold unlawful and set aside agency action, findings, and
conclusions found to be . . . not in accordance with law.”
§706(2)(A).
The APA thus codifies for agency cases the unremarka-
ble, yet elemental proposition reflected by judicial practice
dating back to Marbury: that courts decide legal questions
by applying their own judgment. It specifies that courts,
not agencies, will decide “all relevant questions of law” aris-
ing on review of agency action, §706 (emphasis added)—
even those involving ambiguous laws—and set aside any
such action inconsistent with the law as they interpret it.
And it prescribes no deferential standard for courts to em-
ploy in answering those legal questions. That omission is
telling, because Section 706 does mandate that judicial re-
view of agency policymaking and factfinding be deferential.
See §706(2)(A) (agency action to be set aside if “arbitrary,
capricious, [or] an abuse of discretion”); §706(2)(E) (agency
factfinding in formal proceedings to be set aside if “unsup-
ported by substantial evidence”).
In a statute designed to “serve as the fundamental char-
ter of the administrative state,” Kisor v. Wilkie, 588 U. S.
558, 580 (2019) (plurality opinion) (internal quotation
marks omitted), Congress surely would have articulated a
similarly deferential standard applicable to questions of
law had it intended to depart from the settled pre-APA un-
derstanding that deciding such questions was “exclusively
a judicial function,” American Trucking Assns., 310 U. S.,
at 544. But nothing in the APA hints at such a dramatic
departure. On the contrary, by directing courts to “inter-
pret constitutional and statutory provisions” without differ-
entiating between the two, Section 706 makes clear that
Cite as: 603 U. S. ____ (2024) 15

Opinion of the Court

agency interpretations of statutes—like agency interpreta-
tions of the Constitution—are not entitled to deference. Un-
der the APA, it thus “remains the responsibility of the court
to decide whether the law means what the agency says.”
Perez v. Mortgage Bankers Assn., 575 U. S. 92, 109 (2015)
(Scalia, J., concurring in judgment).4
The text of the APA means what it says. And a look at
its history if anything only underscores that plain meaning.
According to both the House and Senate Reports on the leg-
islation, Section 706 “provide[d] that questions of law are
for courts rather than agencies to decide in the last analy-
sis.” H. R. Rep. No. 1980, 79th Cong., 2d Sess., 44 (1946)
(emphasis added); accord, S. Rep. No. 752, 79th Cong., 1st
Sess., 28 (1945). Some of the legislation’s most prominent
supporters articulated the same view. See 92 Cong. Rec.
5654 (1946) (statement of Rep. Walter); P. McCarran, Im-
proving “Administrative Justice”: Hearings and Evidence;
Scope of Judicial Review, 32 A. B. A. J. 827, 831 (1946).
Even the Department of Justice—an agency with every in-
centive to endorse a view of the APA favorable to the Exec-
utive Branch—opined after its enactment that Section 706
merely “restate[d] the present law as to the scope of judicial
review.” Dept. of Justice, Attorney General’s Manual on the

——————
4 The dissent observes that Section 706 does not say expressly that

courts are to decide legal questions using “a de novo standard of review.”
Post, at 16. That much is true. But statutes can be sensibly understood
only “by reviewing text in context.” Pulsifer v. United States, 601 U. S.
124, 133 (2024). Since the start of our Republic, courts have “decide[d]
. . . questions of law” and “interpret[ed] constitutional and statutory pro-
visions” by applying their own legal judgment. §706. Setting aside its
misplaced reliance on Gray and Hearst, the dissent does not and could
not deny that tradition. But it nonetheless insists that to codify that
tradition, Congress needed to expressly reject a sort of deference the
courts had never before applied—and would not apply for several dec-
ades to come. It did not. “The notion that some things ‘go without saying’
applies to legislation just as it does to everyday life.” Bond v. United
States, 572 U. S. 844, 857 (2014).
16 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

Administrative Procedure Act 108 (1947); see also Kisor,
588 U. S., at 582 (plurality opinion) (same). That “present
law,” as we have described, adhered to the traditional con-
ception of the judicial function. See supra, at 9–13.
Various respected commentators contemporaneously
maintained that the APA required reviewing courts to ex-
ercise independent judgment on questions of law. Professor
John Dickinson, for example, read the APA to “impose a
clear mandate that all [questions of law] shall be decided by
the reviewing Court itself, and in the exercise of its own in-
dependent judgment.” Administrative Procedure Act:
Scope and Grounds of Broadened Judicial Review, 33
A. B. A. J. 434, 516 (1947). Professor Bernard Schwartz
noted that §706 “would seem . . . to be merely a legislative
restatement of the familiar review principle that questions
of law are for the reviewing court, at the same time leaving
to the courts the task of determining in each case what are
questions of law.” Mixed Questions of Law and Fact and
the Administrative Procedure Act, 19 Ford. L. Rev. 73, 84–
85 (1950). And Professor Louis Jaffe, who had served in
several agencies at the advent of the New Deal, thought
that §706 leaves it up to the reviewing “court” to “decide as
a ‘question of law’ whether there is ‘discretion’ in the prem-
ises”—that is, whether the statute at issue delegates par-
ticular discretionary authority to an agency. Judicial Con-
trol of Administrative Action 570 (1965).
The APA, in short, incorporates the traditional under-
standing of the judicial function, under which courts must
exercise independent judgment in determining the mean-
ing of statutory provisions. In exercising such judgment,
though, courts may—as they have from the start—seek aid
from the interpretations of those responsible for imple-
menting particular statutes. Such interpretations “consti-
tute a body of experience and informed judgment to which
courts and litigants may properly resort for guidance” con-
sistent with the APA. Skidmore, 323 U. S., at 140. And
Cite as: 603 U. S. ____ (2024) 17

Opinion of the Court

interpretations issued contemporaneously with the statute
at issue, and which have remained consistent over time,
may be especially useful in determining the statute’s mean-
ing. See ibid.; American Trucking Assns., 310 U. S., at 549.
In a case involving an agency, of course, the statute’s
meaning may well be that the agency is authorized to exer-
cise a degree of discretion. Congress has often enacted such
statutes. For example, some statutes “expressly delegate[ ]”
to an agency the authority to give meaning to a particular
statutory term. Batterton v. Francis, 432 U. S. 416, 425
(1977) (emphasis deleted).5 Others empower an agency to
prescribe rules to “fill up the details” of a statutory scheme,
Wayman v. Southard, 10 Wheat. 1, 43 (1825), or to regulate
subject to the limits imposed by a term or phrase that
“leaves agencies with flexibility,” Michigan v. EPA, 576
U. S. 743, 752 (2015), such as “appropriate” or “reasona-
ble.”6

Opinion of the Court

discretionary authority to an agency, the role of the review-
ing court under the APA is, as always, to independently in-
terpret the statute and effectuate the will of Congress sub-
ject to constitutional limits. The court fulfills that role by
recognizing constitutional delegations, “fix[ing] the bound-
aries of [the] delegated authority,” H. Monaghan, Marbury
and the Administrative State, 83 Colum. L. Rev. 1, 27
(1983), and ensuring the agency has engaged in “ ‘reasoned
decisionmaking’ ” within those boundaries, Michigan, 576
U. S., at 750 (quoting Allentown Mack Sales & Service, Inc.
v. NLRB, 522 U. S. 359, 374 (1998)); see also Motor Vehicle
Mfrs. Assn. of United States, Inc. v. State Farm Mut. Auto-
mobile Ins. Co., 463 U. S. 29 (1983). By doing so, a court
upholds the traditional conception of the judicial function
that the APA adopts.

The deference that Chevron requires of courts reviewing
agency action cannot be squared with the APA.
A
In the decades between the enactment of the APA and
this Court’s decision in Chevron, courts generally continued
to review agency interpretations of the statutes they admin-
ister by independently examining each statute to determine
its meaning. Cf. T. Merrill, Judicial Deference to Executive
Precedent, 101 Yale L. J. 969, 972–975 (1992). As an early
proponent (and later critic) of Chevron recounted, courts
during this period thus identified delegations of discretion-
ary authority to agencies on a “statute-by-statute basis.” A.
Scalia, Judicial Deference to Administrative Interpreta-
tions of Law, 1989 Duke L. J. 511, 516.
Chevron, decided in 1984 by a bare quorum of six Jus-
tices, triggered a marked departure from the traditional ap-
proach. The question in the case was whether an EPA reg-
ulation “allow[ing] States to treat all of the pollution-

emitting devices within the same industrial grouping as
though they were encased within a single ‘bubble’ ” was con-
sistent with the term “stationary source” as used in the
Clean Air Act. 467 U. S., at 840. To answer that question
of statutory interpretation, the Court articulated and em-
ployed a now familiar two-step approach broadly applicable
to review of agency action.
The first step was to discern “whether Congress ha[d] di-
rectly spoken to the precise question at issue.” Id., at 842.
The Court explained that “[i]f the intent of Congress is
clear, that is the end of the matter,” ibid., and courts were
therefore to “reject administrative constructions which are
contrary to clear congressional intent,” id., at 843, n. 9. To
discern such intent, the Court noted, a reviewing court was
to “employ[ ] traditional tools of statutory construction.”
Ibid.
Without mentioning the APA, or acknowledging any doc-
trinal shift, the Court articulated a second step applicable
when “Congress ha[d] not directly addressed the precise
question at issue.” Id., at 843. In such a case—that is, a
case in which “the statute [was] silent or ambiguous with
respect to the specific issue” at hand—a reviewing court
could not “simply impose its own construction on the stat-
ute, as would be necessary in the absence of an administra-
tive interpretation.” Ibid. (footnote omitted). A court in-
stead had to set aside the traditional interpretive tools and
defer to the agency if it had offered “a permissible construc-
tion of the statute,” ibid., even if not “the reading the court
would have reached if the question initially had arisen in a
judicial proceeding,” ibid., n. 11. That directive was justi-
fied, according to the Court, by the understanding that ad-
ministering statutes “requires the formulation of policy” to
fill statutory “gap[s]”; by the long judicial tradition of ac-
cording “considerable weight” to Executive Branch inter-
pretations; and by a host of other considerations, including
the complexity of the regulatory scheme, EPA’s “detailed

Opinion of the Court

and reasoned” consideration, the policy-laden nature of the
judgment supposedly required, and the agency’s indirect ac-
countability to the people through the President. Id., at
843, 844, and n. 14, 865.
Employing this new test, the Court concluded that Con-
gress had not addressed the question at issue with the nec-
essary “level of specificity” and that EPA’s interpretation
was “entitled to deference.” Id., at 865. It did not matter
why Congress, as the Court saw it, had not squarely ad-
dressed the question, see ibid., or that “the agency ha[d]
from time to time changed its interpretation,” id., at 863.
The latest EPA interpretation was a permissible reading of
the Clean Air Act, so under the Court’s new rule, that read-
ing controlled.
Initially, Chevron “seemed destined to obscurity.” T.
Merrill, The Story of Chevron: The Making of an Accidental
Landmark, 66 Admin. L. Rev. 253, 276 (2014). The Court
did not at first treat it as the watershed decision it was
fated to become; it was hardly cited in cases involving stat-
utory questions of agency authority. See ibid. But within
a few years, both this Court and the courts of appeals were
routinely invoking its two-step framework as the governing
standard in such cases. See id., at 276–277. As the Court
did so, it revisited the doctrine’s justifications. Eventually,
the Court decided that Chevron rested on “a presumption
that Congress, when it left ambiguity in a statute meant for
implementation by an agency, understood that the ambigu-
ity would be resolved, first and foremost, by the agency, and
desired the agency (rather than the courts) to possess what-
ever degree of discretion the ambiguity allows.” Smiley v.
Citibank (South Dakota), N. A., 517 U. S. 735, 740–741
(1996); see also, e.g., Cuozzo Speed Technologies, LLC v.
Lee, 579 U. S. 261, 276–277 (2016); Utility Air Regulatory

Opinion of the Court

B
Neither Chevron nor any subsequent decision of this
Court attempted to reconcile its framework with the APA.
The “law of deference” that this Court has built on the foun-
dation laid in Chevron has instead been “[h]eedless of the
original design” of the APA. Perez, 575 U. S., at 109 (Scalia,
J., concurring in judgment).
1
Chevron defies the command of the APA that “the review-
ing court”—not the agency whose action it reviews—is to
“decide all relevant questions of law” and “interpret . . .
statutory provisions.” §706 (emphasis added). It requires
a court to ignore, not follow, “the reading the court would
have reached” had it exercised its independent judgment as
required by the APA. Chevron, 467 U. S., at 843, n. 11. And
although exercising independent judgment is consistent
with the “respect” historically given to Executive Branch in-
terpretations, see, e.g., Edwards’ Lessee, 12 Wheat., at 210;
Skidmore, 323 U. S., at 140, Chevron insists on much more.
It demands that courts mechanically afford binding defer-
ence to agency interpretations, including those that have
been inconsistent over time. See 467 U. S., at 863. Still
worse, it forces courts to do so even when a pre-existing ju-
dicial precedent holds that the statute means something
else—unless the prior court happened to also say that the
statute is “unambiguous.” Brand X, 545 U. S., at 982. That
regime is the antithesis of the time honored approach the
APA prescribes. In fretting over the prospect of “allow[ing]”
a judicial interpretation of a statute “to override an
agency’s” in a dispute before a court, ibid., Chevron turns
the statutory scheme for judicial review of agency action up-
side down.
Chevron cannot be reconciled with the APA, as the Gov-
ernment and the dissent contend, by presuming that statu-
tory ambiguities are implicit delegations to agencies. See
22 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

Brief for Respondents in No. 22–1219, pp. 13, 37–38; post,
at 4–15 (opinion of KAGAN, J.). Presumptions have their
place in statutory interpretation, but only to the extent that
they approximate reality. Chevron’s presumption does not,
because “[a]n ambiguity is simply not a delegation of law-
interpreting power. Chevron confuses the two.” C. Sun-
stein, Interpreting Statutes in the Regulatory State, 103
Harv. L. Rev. 405, 445 (1989). As Chevron itself noted, am-
biguities may result from an inability on the part of Con-
gress to squarely answer the question at hand, or from a
failure to even “consider the question” with the requisite
precision. 467 U. S., at 865. In neither case does an ambi-
guity necessarily reflect a congressional intent that an
agency, as opposed to a court, resolve the resulting inter-
pretive question. And many or perhaps most statutory am-
biguities may be unintentional. As the Framers recognized,
ambiguities will inevitably follow from “the complexity of
objects, . . . the imperfection of the human faculties,” and
the simple fact that “no language is so copious as to supply
words and phrases for every complex idea.” The Federalist
No. 37, at 236.
Courts, after all, routinely confront statutory ambiguities
in cases having nothing to do with Chevron—cases that do
not involve agency interpretations or delegations of author-
ity. Of course, when faced with a statutory ambiguity in
such a case, the ambiguity is not a delegation to anybody,
and a court is not somehow relieved of its obligation to in-
dependently interpret the statute. Courts in that situation
do not throw up their hands because “Congress’s instruc-
tions have” supposedly “run out,” leaving a statutory “gap.”
Post, at 2 (opinion of KAGAN, J.). Courts instead under-
stand that such statutes, no matter how impenetrable, do—
in fact, must—have a single, best meaning. That is the
whole point of having written statutes; “every statute’s
meaning is fixed at the time of enactment.” Wisconsin Cen-

Opinion of the Court

tral Ltd. v. United States, 585 U. S. 274, 284 (2018) (empha-
sis deleted). So instead of declaring a particular party’s
reading “permissible” in such a case, courts use every tool
at their disposal to determine the best reading of the stat-
ute and resolve the ambiguity.
In an agency case as in any other, though, even if some
judges might (or might not) consider the statute ambiguous,
there is a best reading all the same—“the reading the court
would have reached” if no agency were involved. Chevron,
467 U. S., at 843, n. 11. It therefore makes no sense to
speak of a “permissible” interpretation that is not the one
the court, after applying all relevant interpretive tools, con-
cludes is best. In the business of statutory interpretation,
if it is not the best, it is not permissible.
Perhaps most fundamentally, Chevron’s presumption is
misguided because agencies have no special competence in
resolving statutory ambiguities. Courts do. The Framers,
as noted, anticipated that courts would often confront stat-
utory ambiguities and expected that courts would resolve
them by exercising independent legal judgment. And even
Chevron itself reaffirmed that “[t]he judiciary is the final
authority on issues of statutory construction” and recog-
nized that “in the absence of an administrative interpreta-
tion,” it is “necessary” for a court to “impose its own con-
struction on the statute.” Id., at 843, and n. 9. Chevron
gravely erred, though, in concluding that the inquiry is fun-
damentally different just because an administrative inter-
pretation is in play. The very point of the traditional tools
of statutory construction—the tools courts use every day—
is to resolve statutory ambiguities. That is no less true
when the ambiguity is about the scope of an agency’s own
power—perhaps the occasion on which abdication in favor
of the agency is least appropriate.

The Government responds that Congress must generally
24 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

intend for agencies to resolve statutory ambiguities because
agencies have subject matter expertise regarding the stat-
utes they administer; because deferring to agencies pur-
portedly promotes the uniform construction of federal law;
and because resolving statutory ambiguities can involve
policymaking best left to political actors, rather than courts.
See Brief for Respondents in No. 22–1219, pp. 16–19. The
dissent offers more of the same. See post, at 9–14. But none
of these considerations justifies Chevron’s sweeping pre-
sumption of congressional intent.
Beginning with expertise, we recently noted that inter-
pretive issues arising in connection with a regulatory
scheme often “may fall more naturally into a judge’s baili-
wick” than an agency’s. Kisor, 588 U. S., at 578 (opinion of
the Court). We thus observed that “[w]hen the agency has
no comparative expertise in resolving a regulatory ambigu-
ity, Congress presumably would not grant it that author-
ity.” Ibid. Chevron’s broad rule of deference, though, de-
mands that courts presume just the opposite. Under that
rule, ambiguities of all stripes trigger deference. Indeed,
the Government and, seemingly, the dissent continue to de-
fend the proposition that Chevron applies even in cases hav-
ing little to do with an agency’s technical subject matter ex-
pertise. See Brief for Respondents in No. 22–1219, p. 17;
post, at 10.
But even when an ambiguity happens to implicate a tech-
nical matter, it does not follow that Congress has taken the
power to authoritatively interpret the statute from the
courts and given it to the agency. Congress expects courts
to handle technical statutory questions. “[M]any statutory
cases” call upon “courts [to] interpret the mass of technical
detail that is the ordinary diet of the law,” Egelhoff v.
Egelhoff, 532 U. S. 141, 161 (2001) (Breyer, J., dissenting),
and courts did so without issue in agency cases before Chev-
ron, see post, at 30 (GORSUCH, J., concurring). Courts, after
all, do not decide such questions blindly. The parties and
Cite as: 603 U. S. ____ (2024) 25

Opinion of the Court

amici in such cases are steeped in the subject matter, and
reviewing courts have the benefit of their perspectives. In
an agency case in particular, the court will go about its task
with the agency’s “body of experience and informed judg-
ment,” among other information, at its disposal. Skidmore,
323 U. S., at 140. And although an agency’s interpretation
of a statute “cannot bind a court,” it may be especially in-
formative “to the extent it rests on factual premises within
[the agency’s] expertise.” Bureau of Alcohol, Tobacco and
Firearms v. FLRA, 464 U. S. 89, 98, n. 8 (1983). Such ex-
pertise has always been one of the factors which may give
an Executive Branch interpretation particular “power to
persuade, if lacking power to control.” Skidmore, 323 U. S.,
at 140; see, e.g., County of Maui v. Hawaii Wildlife Fund,
590 U. S. 165, 180 (2020); Moore, 95 U. S., at 763.
For those reasons, delegating ultimate interpretive au-
thority to agencies is simply not necessary to ensure that
the resolution of statutory ambiguities is well informed by
subject matter expertise. The better presumption is there-
fore that Congress expects courts to do their ordinary job of
interpreting statutes, with due respect for the views of the
Executive Branch. And to the extent that Congress and the
Executive Branch may disagree with how the courts have
performed that job in a particular case, they are of course
always free to act by revising the statute.
Nor does a desire for the uniform construction of federal
law justify Chevron. Given inconsistencies in how judges
apply Chevron, see infra, at 30–33, it is unclear how much
the doctrine as a whole (as opposed to its highly deferential
second step) actually promotes such uniformity. In any
event, there is little value in imposing a uniform interpre-
tation of a statute if that interpretation is wrong. We see
no reason to presume that Congress prefers uniformity for
uniformity’s sake over the correct interpretation of the laws
it enacts.
26 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

The view that interpretation of ambiguous statutory pro-
visions amounts to policymaking suited for political actors
rather than courts is especially mistaken, for it rests on a
profound misconception of the judicial role. It is reasonable
to assume that Congress intends to leave policymaking to
political actors. But resolution of statutory ambiguities in-
volves legal interpretation. That task does not suddenly be-
come policymaking just because a court has an “agency to
fall back on.” Kisor, 588 U. S., at 575 (opinion of the Court).
Courts interpret statutes, no matter the context, based on
the traditional tools of statutory construction, not individ-
ual policy preferences. Indeed, the Framers crafted the
Constitution to ensure that federal judges could exercise
judgment free from the influence of the political branches.
See The Federalist, No. 78, at 522–525. They were to con-
strue the law with “[c]lear heads . . . and honest hearts,” not
with an eye to policy preferences that had not made it into
the statute. 1 Works of James Wilson 363 (J. Andrews ed.
1896).
That is not to say that Congress cannot or does not confer
discretionary authority on agencies. Congress may do so,
subject to constitutional limits, and it often has. But to stay
out of discretionary policymaking left to the political
branches, judges need only fulfill their obligations under
the APA to independently identify and respect such delega-
tions of authority, police the outer statutory boundaries of
those delegations, and ensure that agencies exercise their
discretion consistent with the APA. By forcing courts to in-
stead pretend that ambiguities are necessarily delegations,
Chevron does not prevent judges from making policy. It
prevents them from judging.
3
In truth, Chevron’s justifying presumption is, as Mem-
bers of this Court have often recognized, a fiction. See Buff-
ington v. McDonough, 598 U. S. ___, ___ (2022) (GORSUCH,
Cite as: 603 U. S. ____ (2024) 27

J., dissenting from denial of certiorari) (slip op., at 11);
Cuozzo, 579 U. S., at 286 (THOMAS, J., concurring); Scalia,
1989 Duke L. J., at 517; see also post, at 15 (opinion of
KAGAN, J.). So we have spent the better part of four decades
imposing one limitation on Chevron after another, pruning
its presumption on the understanding that “where it is in
doubt that Congress actually intended to delegate particu-
lar interpretive authority to an agency, Chevron is ‘inappli-
cable.’ ” United States v. Mead Corp., 533 U. S. 218, 230
(2001) (quoting Christensen v. Harris County, 529 U. S. 576,
597 (2000) (Breyer, J., dissenting)); see also Adams Fruit
Co. v. Barrett, 494 U. S. 638, 649 (1990).
Consider the many refinements we have made in an ef-
fort to match Chevron’s presumption to reality. We have
said that Chevron applies only “when it appears that Con-
gress delegated authority to the agency generally to make
rules carrying the force of law, and that the agency inter-
pretation claiming deference was promulgated in the exer-
cise of that authority.” Mead, 533 U. S., at 226–227. In
practice, that threshold requirement—sometimes called
Chevron “step zero”—largely limits Chevron to “the fruits of
notice-and-comment rulemaking or formal adjudication.”
533 U. S., at 230. But even when those processes are used,
deference is still not warranted “where the regulation is
‘procedurally defective’—that is, where the agency errs by
failing to follow the correct procedures in issuing the regu-
lation.” Encino Motorcars, LLC v. Navarro, 579 U. S. 211,
220 (2016) (quoting Mead, 533 U. S., at 227).
Even where those procedural hurdles are cleared, sub-
stantive ones remain. Most notably, Chevron does not ap-
ply if the question at issue is one of “deep ‘economic and
political significance.’ ” King v. Burwell, 576 U. S. 473, 486
(2015). We have instead expected Congress to delegate
such authority “expressly” if at all, ibid., for “[e]xtraordi-
nary grants of regulatory authority are rarely accomplished
through ‘modest words,’ ‘vague terms,’ or ‘subtle device[s],’ ”

Whitman v. American Trucking Assns., Inc., 531 U. S. 457,

Chevron to agency interpretations of judicial review provi-
sions, see Adams Fruit Co., 494 U. S., at 649–650, or to stat-
utory schemes not administered by the agency seeking def-
erence, see Epic Systems Corp. v. Lewis, 584 U. S. 497, 519–
520 (2018). And we have sent mixed signals on whether
Chevron applies when a statute has criminal applications.
Compare Abramski v. United States, 573 U. S. 169, 191
(2014), with Babbitt v. Sweet Home Chapter, Communities
for Great Ore., 515 U. S. 687, 704, n. 18 (1995).
Confronted with this byzantine set of preconditions and
exceptions, some courts have simply bypassed Chevron,
saying it makes no difference for one reason or another.7
And even when they do invoke Chevron, courts do not al-
ways heed the various steps and nuances of that evolving
doctrine. In one of the cases before us today, for example,
the First Circuit both skipped “step zero,” see 62 F. 4th, at
628, and refused to “classify [its] conclusion as a product of
Chevron step one or step two”—though it ultimately ap-
pears to have deferred under step two, id., at 634.

Opinion of the Court

This Court, for its part, has not deferred to an agency in-
terpretation under Chevron since 2016. See Cuozzo, 579
U. S., at 280 (most recent occasion). But Chevron remains
on the books. So litigants must continue to wrestle with it,
and lower courts—bound by even our crumbling prece-
dents, see Agostini v. Felton, 521 U. S. 203, 238 (1997)—
understandably continue to apply it.
The experience of the last 40 years has thus done little to
rehabilitate Chevron. It has only made clear that Chevron’s
fictional presumption of congressional intent was always
unmoored from the APA’s demand that courts exercise in-
dependent judgment in construing statutes administered
by agencies. At best, our intricate Chevron doctrine has
been nothing more than a distraction from the question
that matters: Does the statute authorize the challenged
agency action? And at worst, it has required courts to vio-
late the APA by yielding to an agency the express responsi-
bility, vested in “the reviewing court,” to “decide all relevant
questions of law” and “interpret . . . statutory provisions.”
§706 (emphasis added).
IV
The only question left is whether stare decisis, the doc-
trine governing judicial adherence to precedent, requires us
to persist in the Chevron project. It does not. Stare decisis
is not an “inexorable command,” Payne v. Tennessee, 501
U. S. 808, 828 (1991), and the stare decisis considerations
most relevant here—“the quality of [the precedent’s] rea-
soning, the workability of the rule it established, . . . and
reliance on the decision,” Knick v. Township of Scott, 588
U. S. 180, 203 (2019) (quoting Janus v. State, County, and
Municipal Employees, 585 U. S. 878, 917 (2018))—all weigh
in favor of letting Chevron go.
Chevron has proved to be fundamentally misguided. De-
spite reshaping judicial review of agency action, neither it
nor any case of ours applying it grappled with the APA—

Opinion of the Court

the statute that lays out how such review works. Its flaws
were nonetheless apparent from the start, prompting this
Court to revise its foundations and continually limit its ap-
plication. It has launched and sustained a cottage industry
of scholars attempting to decipher its basis and meaning.
And Members of this Court have long questioned its prem-
ises. See, e.g., Pereira v. Sessions, 585 U. S. 198, 219–221
(2018) (Kennedy, J., concurring); Michigan, 576 U. S., at
760–764 (THOMAS, J., concurring); Buffington, 598 U. S.
___ (opinion of GORSUCH, J.); B. Kavanaugh, Fixing Statu-
tory Interpretation, 129 Harv. L. Rev. 2118, 2150–2154
(2016). Even Justice Scalia, an early champion of Chevron,
came to seriously doubt whether it could be reconciled with
the APA. See Perez, 575 U. S., at 109–110 (opinion concur-
ring in judgment). For its entire existence, Chevron has
been a “rule in search of a justification,” Knick, 588 U. S.,
at 204, if it was ever coherent enough to be called a rule at
all.
Experience has also shown that Chevron is unworkable.
The defining feature of its framework is the identification
of statutory ambiguity, which requires deference at the doc-
trine’s second step. But the concept of ambiguity has al-
ways evaded meaningful definition. As Justice Scalia put
the dilemma just five years after Chevron was decided:
“How clear is clear?” 1989 Duke L. J., at 521.
We are no closer to an answer to that question than we
were four decades ago. “ ‘[A]mbiguity’ is a term that may
have different meanings for different judges.” Exxon Mobil
Corp. v. Allapattah Services, Inc., 545 U. S. 546, 572 (2005)

beholder,” Exxon Mobil Corp., 545 U. S., at 572 (Stevens, J.,
dissenting), invites different results in like cases and is
therefore “arbitrary in practice,” Gulfstream Aerospace
Corp. v. Mayacamas Corp., 485 U. S. 271, 283 (1988). Such
an impressionistic and malleable concept “cannot stand as
an every-day test for allocating” interpretive authority be-
tween courts and agencies. Swift & Co. v. Wickham, 382
U. S. 111, 125 (1965).
The dissent proves the point. It tells us that a court
should reach Chevron’s second step when it finds, “at the
end of its interpretive work,” that “Congress has left an am-
biguity or gap.” Post, at 1–2. (The Government offers a
similar test. See Brief for Respondents in No. 22–1219,
pp. 7, 10, 14; Tr. of Oral Arg. 113–114, 116.) That is no
guide at all. Once more, the basic nature and meaning of a
statute does not change when an agency happens to be in-
volved. Nor does it change just because the agency has hap-
pened to offer its interpretation through the sort of proce-
dures necessary to obtain deference, or because the other
preconditions for Chevron happen to be satisfied. The stat-
ute still has a best meaning, necessarily discernible by a
court deploying its full interpretive toolkit. So for the dis-
sent’s test to have any meaning, it must think that in an
agency case (unlike in any other), a court should give up on
its “interpretive work” before it has identified that best
meaning. But how does a court know when to do so? On
that point, the dissent leaves a gap of its own. It protests
only that some other interpretive tools—all with pedigrees
more robust than Chevron’s, and all designed to help courts
identify the meaning of a text rather than allow the Execu-
tive Branch to displace it—also apply to ambiguous texts.
See post, at 27. That this is all the dissent can come up
with, after four decades of judicial experience attempting to
identify ambiguity under Chevron, reveals the futility of the

exercise.8
Because Chevron in its original, two-step form was so in-
determinate and sweeping, we have instead been forced to
clarify the doctrine again and again. Our attempts to do so
have only added to Chevron’s unworkability, transforming
the original two-step into a dizzying breakdance. See Ad-
ams Fruit Co., 494 U. S., at 649–650; Mead, 533 U. S., at
226–227; King, 576 U. S., at 486; Encino Motorcars, 579
U. S., at 220; Epic Systems, 584 U. S., at 519–520; on and
on. And the doctrine continues to spawn difficult threshold
questions that promise to further complicate the inquiry
should Chevron be retained. See, e.g., Cargill v. Garland,
57 F. 4th 447, 465–468 (CA5 2023) (plurality opinion) (May
the Government waive reliance on Chevron? Does Chevron
apply to agency interpretations of statutes imposing crimi-
nal penalties? Does Chevron displace the rule of lenity?),
aff ’d, 602 U. S. ___ (2024).
Four decades after its inception, Chevron has thus be-
come an impediment, rather than an aid, to accomplishing
the basic judicial task of “say[ing] what the law is.” Mar-
bury, 1 Cranch, at 177. And its continuing import is far
from clear. Courts have often declined to engage with the
doctrine, saying it makes no difference. See n. 7, supra.
And as noted, we have avoided deferring under Chevron
since 2016. That trend is nothing new; for decades, we have
often declined to invoke Chevron even in those cases where
it might appear to be applicable. See W. Eskridge & L.
Baer, The Continuum of Deference: Supreme Court Treat-
ment of Agency Statutory Interpretations From Chevron to
Hamdan, 96 Geo. L. J. 1083, 1125 (2008). At this point, all

8 Citing an empirical study, the dissent adds that Chevron “fosters

agreement among judges.” Post, at 28. It is hardly surprising that a
study might find as much; Chevron’s second step is supposed to be hos-
pitable to agency interpretations. So when judges get there, they tend to
agree that the agency wins. That proves nothing about the supposed
ease or predictability of identifying ambiguity in the first place.

Opinion of the Court

that remains of Chevron is a decaying husk with bold pre-
tensions.
Nor has Chevron been the sort of “ ‘stable background’
rule” that fosters meaningful reliance. Post, at 8, n. 1 (opin-
ion of KAGAN, J.) (quoting Morrison v. National Australia
Bank Ltd., 561 U. S. 247, 261 (2010)). Given our constant
tinkering with and eventual turn away from Chevron, and
its inconsistent application by the lower courts, it instead is
hard to see how anyone—Congress included—could reason-
ably expect a court to rely on Chevron in any particular
case. And even if it were possible to predict accurately
when courts will apply Chevron, the doctrine “does not pro-
vide ‘a clear or easily applicable standard, so arguments for
reliance based on its clarity are misplaced.’ ” Janus, 585
U. S., at 927 (quoting South Dakota v. Wayfair, Inc., 585
U. S. 162, 186 (2018)). To plan on Chevron yielding a par-
ticular result is to gamble not only that the doctrine will be
invoked, but also that it will produce readily foreseeable
outcomes and the stability that comes with them. History
has proved neither bet to be a winning proposition.
Rather than safeguarding reliance interests, Chevron af-
firmatively destroys them. Under Chevron, a statutory am-
biguity, no matter why it is there, becomes a license author-
izing an agency to change positions as much as it likes, with
“[u]nexplained inconsistency” being “at most . . . a reason
for holding an interpretation to be . . . arbitrary and capri-
cious.” Brand X, 545 U. S., at 981. But statutory ambigu-
ity, as we have explained, is not a reliable indicator of ac-
tual delegation of discretionary authority to agencies.
Chevron thus allows agencies to change course even when
Congress has given them no power to do so. By its sheer
breadth, Chevron fosters unwarranted instability in the
law, leaving those attempting to plan around agency action
in an eternal fog of uncertainty.
Chevron accordingly has undermined the very “rule of
law” values that stare decisis exists to secure. Michigan v.
34 LOPER BRIGHT ENTERPRISES v. RAIMONDO

Opinion of the Court

Bay Mills Indian Community, 572 U. S. 782, 798 (2014).
And it cannot be constrained by admonishing courts to be
extra careful, or by tacking on a new batch of conditions.
We would need to once again “revis[e] its theoretical basis
. . . in order to cure its practical deficiencies.” Montejo v.
Louisiana, 556 U. S. 778, 792 (2009). Stare decisis does not
require us to do so, especially because any refinements we
might make would only point courts back to their duties un-
der the APA to “decide all relevant questions of law” and
“interpret . . . statutory provisions.” §706. Nor is there any
reason to wait helplessly for Congress to correct our mis-
take. The Court has jettisoned many precedents that Con-
gress likewise could have legislatively overruled. See, e.g.,
Patterson v. McLean Credit Union, 485 U. S. 617, 618
(1988) (per curiam) (collecting cases). And part of “judicial
humility,” post, at 3, 25 (opinion of KAGAN, J.,), is admitting
and in certain cases correcting our own mistakes, especially
when those mistakes are serious, see post, at 8–9 (opinion
of GORSUCH, J.).
This is one of those cases. Chevron was a judicial inven-
tion that required judges to disregard their statutory du-
ties. And the only way to “ensure that the law will not
merely change erratically, but will develop in a principled
and intelligible fashion,” Vasquez v. Hillery, 474 U. S. 254,
265 (1986), is for us to leave Chevron behind.
By doing so, however, we do not call into question prior
cases that relied on the Chevron framework. The holdings
of those cases that specific agency actions are lawful—in-
cluding the Clean Air Act holding of Chevron itself—are
still subject to statutory stare decisis despite our change in
interpretive methodology. See CBOCS West, Inc. v. Hum-
phries, 553 U. S. 442, 457 (2008). Mere reliance on Chevron
cannot constitute a “ ‘special justification’ ” for overruling
such a holding, because to say a precedent relied on Chev-
ron is, at best, “just an argument that the precedent was
wrongly decided.” Halliburton Co. v. Erica P. John Fund,
Cite as: 603 U. S. ____ (2024) 35

Opinion of the Court

Inc., 573 U. S. 258, 266 (2014) (quoting Dickerson v. United
States, 530 U. S. 428, 443 (2000)). That is not enough to
justify overruling a statutory precedent.
* * *
The dissent ends by quoting Chevron: “ ‘Judges are not
experts in the field.’ ” Post, at 31 (quoting 467 U. S., at 865).
That depends, of course, on what the “field” is. If it is legal
interpretation, that has been, “emphatically,” “the province
and duty of the judicial department” for at least 221 years.
Marbury, 1 Cranch, at 177. The rest of the dissent’s se-
lected epigraph is that judges “ ‘are not part of either politi-
cal branch.’ ” Post, at 31 (quoting Chevron, 467 U. S., at
865). Indeed. Judges have always been expected to apply
their “judgment” independent of the political branches
when interpreting the laws those branches enact. The Fed-
eralist No. 78, at 523. And one of those laws, the APA, bars
judges from disregarding that responsibility just because
an Executive Branch agency views a statute differently.
Chevron is overruled. Courts must exercise their inde-
pendent judgment in deciding whether an agency has acted
within its statutory authority, as the APA requires. Careful
attention to the judgment of the Executive Branch may help
inform that inquiry. And when a particular statute dele-
gates authority to an agency consistent with constitutional
limits, courts must respect the delegation, while ensuring
that the agency acts within it. But courts need not and un-
der the APA may not defer to an agency interpretation of
the law simply because a statute is ambiguous.
Because the D. C. and First Circuits relied on Chevron in
deciding whether to uphold the Rule, their judgments are
vacated, and the cases are remanded for further proceed-
ings consistent with this opinion.

It is so ordered.

JUSTICE THOMAS, concurring.
I join the Court’s opinion in full because it correctly con-
cludes that Chevron U. S. A. Inc. v. Natural Resources De-
fense Council, Inc., 467 U. S. 837 (1984), must finally be
overruled. Under Chevron, a judge was required to adopt
an agency’s interpretation of an ambiguous statute, so long
as the agency had a “permissible construction of the stat-
ute.” See id., at 843. As the Court explains, that deference
does not comport with the Administrative Procedure Act,
which requires judges to decide “all relevant questions of
law” and “interpret constitutional and statutory provisions”
when reviewing an agency action. 5 U. S. C. §706; see also
ante, at 18–23; Baldwin v. United States, 589 U. S. ___, ___–
___ (2020) (THOMAS, J., dissenting from denial of certiorari)
(slip op., at 4–5).
2 LOPER BRIGHT ENTERPRISES v. RAIMONDO

THOMAS, J., concurring

I write separately to underscore a more fundamental
problem: Chevron deference also violates our Constitution’s
separation of powers, as I have previously explained at
length. See Baldwin, 589 U. S., at ___–___ (dissenting opin-
ion) (slip op., at 2–4); Michigan v. EPA, 576 U. S. 743, 761–
763 (2015) (concurring opinion); see also Perez v. Mortgage
Bankers Assn., 575 U. S. 92, 115–118 (2015) (opinion con-
curring in judgment). And, I agree with JUSTICE GORSUCH
that we should not overlook Chevron’s constitutional de-
fects in overruling it.* Post, at 15–20 (concurring opinion).
To provide “practical and real protections for individual lib-
erty,” the Framers drafted a Constitution that divides the
legislative, executive, and judicial powers between three
branches of Government. Perez, 575 U. S., at 118 (opinion
of THOMAS, J.). Chevron deference compromises this sepa-
ration of powers in two ways. It curbs the judicial power
afforded to courts, and simultaneously expands agencies’
executive power beyond constitutional limits.
Chevron compels judges to abdicate their Article III “ju-
dicial Power.” §1. “[T]he judicial power, as originally un-
derstood, requires a court to exercise its independent judg-
ment in interpreting and expounding upon the laws.”
Perez, 575 U. S., at 119 (opinion of THOMAS, J.); accord, post,
at 17–18 (opinion of GORSUCH, J.). The Framers under-
stood that “legal texts . . . often contain ambiguities,” and
that the judicial power included “the power to resolve these
ambiguities over time.” Perez, 575 U. S., at 119 (opinion of
THOMAS, J.); accord, ante, at 7–9. But, under Chevron, a
judge must accept an agency’s interpretation of an ambigu-
ous law, even if he thinks another interpretation is correct.

*There is much to be commended in JUSTICE GORSUCH’s careful consid-
eration from first principles of the weight we should afford to our prece-
dent. I agree with the lion’s share of his concurrence. See generally
Gamble v. United States, 587 U. S. 678, 710 (2019) (THOMAS, J., concur-
ring).

THOMAS, J., concurring

exercising their independent judgment to resolve ambigui-
ties. Baldwin, 589 U. S., at ___ (opinion of THOMAS, J.) (slip
op., at 3); see also Michigan, 576 U. S., at 761 (opinion of
THOMAS, J.); see also Perez, 575 U. S., at 123 (opinion of
THOMAS, J.). By tying a judge’s hands, Chevron prevents
the Judiciary from serving as a constitutional check on the
Executive. It allows “the Executive . . . to dictate the out-
come of cases through erroneous interpretations.” Bald-
win, 589 U. S., at ___ (opinion of THOMAS, J.) (slip op., at 4);
Michigan, 576 U. S., at 763, n. 1 (opinion of THOMAS, J.);
see also Perez, 575 U. S., at 124 (opinion of THOMAS, J.). Be-
cause the judicial power requires judges to exercise their
independent judgment, the deference that Chevron re-
quires contravenes Article III’s mandate.
Chevron deference also permits the Executive Branch to
exercise powers not given to it. “When the Government is
called upon to perform a function that requires an exercise
of legislative, executive, or judicial power, only the vested
recipient of that power can perform it.” Department of
Transportation v. Association of American Railroads, 575
U. S. 43, 68 (2015) (THOMAS, J., concurring in judgment).
Because the Constitution gives the Executive Branch only
“[t]he executive Power,” executive agencies may constitu-
tionally exercise only that power. Art. II, §1, cl. 1. But,
Chevron gives agencies license to exercise judicial power.
By allowing agencies to definitively interpret laws so long
as they are ambiguous, Chevron “transfer[s]” the Judici-
ary’s “interpretive judgment to the agency.” Perez, 575
U. S., at 124 (opinion of THOMAS, J.); see also Baldwin, 589
U. S., at ___ (opinion of THOMAS, J.) (slip op., at 4); Michi-
gan, 576 U. S., at 761–762 (opinion of THOMAS, J.); post, at
18 (GORSUCH, J., concurring).
Chevron deference “cannot be salvaged” by recasting it as
deference to an agency’s “formulation of policy.” Baldwin,
589 U. S., at ___ (opinion of THOMAS, J.) (internal quotation
marks omitted) (slip op., at 3). If that were true, Chevron
4 LOPER BRIGHT ENTERPRISES v. RAIMONDO

THOMAS, J., concurring

would mean that “agencies are unconstitutionally exercis-
ing ‘legislative Powers’ vested in Congress.” Baldwin, 589
U. S., at ___ (opinion of THOMAS, J.) (slip op., at 3) (quoting
Art. I, §1). By “giv[ing] the force of law to agency pro-
nouncements on matters of private conduct as to which
Congress did not actually have an intent,” Chevron “per-
mit[s] a body other than Congress to perform a function
that requires an exercise of legislative power.” Michigan,
576 U. S., at 762 (opinion of THOMAS, J.) (internal quotation
marks omitted). No matter the gloss put on it, Chevron ex-
pands agencies’ power beyond the bounds of Article II by
permitting them to exercise powers reserved to another
branch of Government.
Chevron deference was “not a harmless transfer of
power.” Baldwin, 589 U. S., at ___ (opinion of THOMAS, J.)
(slip op., at 3). “The Constitution carefully imposes struc-
tural constraints on all three branches, and the exercise of
power free of those accompanying restraints subverts the
design of the Constitution’s ratifiers.” Ibid. In particular,
the Founders envisioned that “the courts [would] check the
Executive by applying the correct interpretation of the law.”
Id., at ___ (slip op., at 4). Chevron was thus a fundamental
disruption of our separation of powers. It improperly strips
courts of judicial power by simultaneously increasing the
power of executive agencies. By overruling Chevron, we re-
store this aspect of our separation of powers. To safeguard
individual liberty, “[s]tructure is everything.” A. Scalia,
Foreword: The Importance of Structure in Constitutional
Interpretation, 83 Notre Dame L. Rev. 1417, 1418 (2008).
Although the Court finally ends our 40-year misadventure
with Chevron deference, its more profound problems should
not be overlooked. Regardless of what a statute says, the
type of deference required by Chevron violates the Consti-
tution.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE FIRST CIRCUIT
[June 28, 2024]

JUSTICE GORSUCH, concurring.
In disputes between individuals and the government
about the meaning of a federal law, federal courts have tra-
ditionally sought to offer independent judgments about
“what the law is” without favor to either side. Marbury v.
Madison, 1 Cranch 137, 177 (1803). Beginning in the mid-
1980s, however, this Court experimented with a radically
different approach. Applying Chevron deference, judges be-
gan deferring to the views of executive agency officials
about the meaning of federal statutes. See Chevron U. S. A.
Inc. v. Natural Resources Defense Council, Inc., 467 U. S.
837 (1984). With time, the error of this approach became
widely appreciated. So much so that this Court has refused
to apply Chevron deference since 2016. Today, the Court
places a tombstone on Chevron no one can miss. In doing
2 LOPER BRIGHT ENTERPRISES v. RAIMONDO

GORSUCH, J., concurring

so, the Court returns judges to interpretive rules that have
guided federal courts since the Nation’s founding. I write
separately to address why the proper application of the doc-
trine of stare decisis supports that course.
I
A
Today, the phrase “common law judge” may call to mind
a judicial titan of the past who brilliantly devised new legal
rules on his own. The phrase “stare decisis” might conjure
up a sense that judges who come later in time are strictly
bound to follow the work of their predecessors. But neither
of those intuitions fairly describes the traditional common-
law understanding of the judge’s role or the doctrine of stare
decisis.
At common law, a judge’s charge to decide cases was not
usually understood as a license to make new law. For much
of England’s early history, different rulers and different le-
gal systems prevailed in different regions. As England con-
solidated into a single kingdom governed by a single legal
system, the judge’s task was to examine those pre-existing
legal traditions and apply in the disputes that came to him
those legal rules that were “common to the whole land and
to all Englishmen.” F. Maitland, Equity, Also the Forms of
Action at Common Law 2 (1929). That was “common law”
judging.
This view of the judge’s role had consequences for the au-
thority due judicial decisions. Because a judge’s job was to
find and apply the law, not make it, the “opinion of the
judge” and “the law” were not considered “one and the same
thing.” 1 W. Blackstone, Commentaries on the Laws of
England 71 (1765) (Blackstone) (emphasis deleted). A
judge’s decision might bind the parties to the case at hand.
M. Hale, The History and Analysis of the Common Law of
England 68 (1713) (Hale). But none of that meant the judge
had the power to “make a Law properly so called” for society
Cite as: 603 U. S. ____ (2024) 3

GORSUCH, J., concurring

at large, “for that only the King and Parliament can do.”
Ibid.
Other consequences followed for the role precedent
played in future judicial proceedings. Because past deci-
sions represented something “less than a Law,” they did not
bind future judges. Ibid. At the same time, as Matthew
Hale put it, a future judge could give a past decision
“Weight” as “Evidence” of the law. Ibid. Expressing the
same idea, William Blackstone conceived of judicial prece-
dents as “evidence” of “the common law.” 1 Blackstone 69,
71. And much like other forms of evidence, precedents at
common law were thought to vary in the weight due them.
Some past decisions might supply future courts with con-
siderable guidance. But others might be entitled to lesser
weight, not least because judges are no less prone to error
than anyone else and they may sometimes “mistake” what
the law demands. Id., at 71 (emphasis deleted). In cases
like that, both men thought, a future judge should not
rotely repeat a past mistake but instead “vindicate” the law
“from misrepresentation.” Id., at 70.
When examining past decisions as evidence of the law,
common law judges did not, broadly speaking, afford over-
whelming weight to any “single precedent.” J. Baker, An
Introduction to English Legal History 209–210 (5th ed.
2019). Instead, a prior decision’s persuasive force depended
in large measure on its “Consonancy and Congruity with
Resolutions and Decisions of former Times.” Hale 68. An
individual decision might reflect the views of one court at
one moment in time, but a consistent line of decisions rep-
resenting the wisdom of many minds across many genera-
tions was generally considered stronger evidence of the
law’s meaning. Ibid.
With this conception of precedent in mind, Lord Mans-
field cautioned against elevating “particular cases” above
the “general principles” that “run through the cases, and
govern the decision of them.” Rust v. Cooper, 2 Cowp. 629,
4 LOPER BRIGHT ENTERPRISES v. RAIMONDO

GORSUCH, J., concurring

632, 98 Eng. Rep. 1277, 1279 (K. B. 1777). By discarding
aberrational rulings and pursuing instead the mainstream
of past decisions, he observed, the common law tended over
time to “wor[k] itself pure.” Omychund v. Barker, 1 Atk. 22,
33, 26 Eng. Rep. 15, 23 (Ch. 1744) (emphasis deleted). Re-
flecting similar thinking, Edmund Burke offered five prin-
ciples for the evaluation of past judicial decisions: “They
ought to be shewn; first, to be numerous and not scattered
here and there;—secondly, concurrent and not contradic-
tory and mutually destructive;—thirdly, to be made in good
and constitutional times;—fourthly, not to be made to serve
an occasion;—and fifthly, to be agreeable to the general
tenor of legal principles.” Speech of Dec. 23, 1790, in 3 The
Speeches of the Right Honourable Edmund Burke 513
(1816).
Not only did different decisions carry different weight, so
did different language within a decision. An opinion’s hold-
ing and the reasoning essential to it (the ratio decidendi)
merited careful attention. Dicta, stray remarks, and di-
gressions warranted less weight. See N. Duxbury, The In-
tricacies of Dicta and Dissent 19–24 (2021) (Duxbury).
These were no more than “the vapours and fumes of law.”
F. Bacon, The Lord Keeper’s Speech in the Exchequer
(1617), in 2 The Works of Francis Bacon 478 (B. Montagu
ed. 1887) (Bacon).
That is not to say those “vapours” were worthless. Often
dicta might provide the parties to a particular dispute a
“fuller understanding of the court’s decisional path or re-
lated areas of concern.” B. Garner et al., The Law of Judi-
cial Precedent 65 (2016) (Precedent). Dicta might also pro-
vide future courts with a source of “thoughtful advice.”
Ibid. But future courts had to be careful not to treat every
“hasty expression . . . as a serious and deliberate opinion.”
Steel v. Houghton, 1 Bl. H. 51, 53, 126 Eng. Rep. 32, 33
(C. P. 1788). To do so would work an “injustice to [the]
memory” of their predecessors who could not expect judicial

GORSUCH, J., concurring

remarks issued in one context to apply perfectly in others,
perhaps especially ones they could not foresee. Ibid. Also,
the limits of the adversarial process, a distinctive feature of
English law, had to be borne in mind. When a single judge
or a small panel reached a decision in a case, they did so
based on the factual record and legal arguments the parties
at hand have chosen to develop. Attuned to those con-
straints, future judges had to proceed with an open mind to
the possibility that different facts and different legal argu-
ments might dictate different outcomes in later disputes.
See Duxbury 19–24.
B
Necessarily, this represents just a quick sketch of tradi-
tional common-law understandings of the judge’s role and
the place of precedent in it. It focuses, too, on the horizon-
tal, not vertical, force of judicial precedents. But there are
good reasons to think that the common law’s understand-
ings of judges and precedent outlined above crossed the At-
lantic and informed the nature of the “judicial Power” the
Constitution vests in federal courts. Art. III, §1.
Not only was the Constitution adopted against the back-
drop of these understandings and, in light of that alone,
they may provide evidence of what the framers meant when
they spoke of the “judicial Power.” Many other, more spe-
cific provisions in the Constitution reflect much the same
distinction between lawmaking and lawfinding functions
the common law did. The Constitution provides that its
terms may be amended only through certain prescribed
democratic processes. Art. V. It vests the power to enact
federal legislation exclusively in the people’s elected repre-
sentatives in Congress. Art. I, §1. Meanwhile, the Consti-
tution describes the judicial power as the power to resolve
cases and controversies. Art. III, §2, cl. 1. As well, it dele-
gates that authority to life-tenured judges, see §1, an as-
signment that would have made little sense if judges could

usurp lawmaking powers vested in periodically elected rep-
resentatives. But one that makes perfect sense if what is
sought is a neutral party “to interpret and apply” the law
without fear or favor in a dispute between others. 2 The
Works of James Wilson 161 (J. Andrews ed. 1896) (Wilson);
see Osborn v. Bank of United States, 9 Wheat. 738, 866
(1824).
The constrained view of the judicial power that runs
through our Constitution carries with it familiar implica-
tions, ones the framers readily acknowledged. James Mad-
ison, for example, proclaimed that it would be a “fallacy” to
suggest that judges or their precedents could “repeal or al-
ter” the Constitution or the laws of the United States. Let-
ter to N. Trist (Dec. 1831), in 9 The Writings of James Mad-
ison 477 (G. Hunt ed. 1910). A court’s opinion, James
Wilson added, may be thought of as “effective la[w]” “[a]s to
the parties.” Wilson 160–161. But as in England, Wilson
said, a prior judicial decision could serve in a future dispute
only as “evidence” of the law’s proper construction. Id., at
160; accord, 1 J. Kent, Commentaries on American Law
442–443 (1826).
The framers also recognized that the judicial power de-
scribed in our Constitution implies, as the judicial power
did in England, a power (and duty) of discrimination when
it comes to assessing the “evidence” embodied in past deci-
sions. So, for example, Madison observed that judicial rul-
ings “repeatedly confirmed ” may supply better evidence of
the law’s meaning than isolated or aberrant ones. Letter to
C. Ingersoll (June 1831), in 4 Letters and Other Writings of
James Madison 184 (1867) (emphasis added). Extending
the thought, Thomas Jefferson believed it would often take
“numerous decisions” for the meaning of new statutes to be-
come truly “settled.” Letter to S. Jones (July 1809), in 12
The Writings of Thomas Jefferson 299 (A. Bergh ed. 1907).
From the start, too, American courts recognized that not
everything found in a prior decision was entitled to equal

weight. As Chief Justice Marshall warned, “It is a maxim
not to be disregarded, that general expressions, in every
opinion, are to be taken in connection with the case in which
those expressions are used.” Cohens v. Virginia, 6 Wheat.
264, 399 (1821). To the extent a past court offered views
“beyond the case,” those expressions “may be respected” in
a later case “but ought not to control the judgment.” Ibid.
One “obvious” reason for this, Marshall continued, had to
do with the limits of the adversarial process we inherited
from England: Only “[t]he question actually before the
Court is investigated with care, and considered in its full
extent. Other principles which may serve to illustrate it,
are considered in their relation to the case decided, but
their possible bearing on all other cases is seldom com-
pletely investigated.” Id., at 399–400.
Abraham Lincoln championed these traditional under-
standings in his debates with Stephen Douglas. Douglas
took the view that a single decision of this Court—no mat-
ter how flawed—could definitively resolve a contested issue
for everyone and all time. Those who thought otherwise, he
said, “aim[ed] a deadly blow to our whole Republican sys-
tem of government.” Speech at Springfield, Ill. (June 26,
1857), in 2 The Collected Works of Abraham Lincoln 401 (R.
Basler ed. 1953) (Lincoln Speech). But Lincoln knew better.
While accepting that judicial decisions “absolutely deter-
mine” the rights of the parties to a court’s judgment, he re-
fused to accept that any single judicial decision could “fully
settl[e]” an issue, particularly when that decision departs
from the Constitution. Id., at 400–401. In cases such as
these, Lincoln explained, “it is not resistance, it is not fac-
tious, it is not even disrespectful, to treat [the decision] as
not having yet quite established a settled doctrine for the
country.” Id., at 401.
After the Civil War, the Court echoed some of these same
points. It stressed that every statement in a judicial opin-
8 LOPER BRIGHT ENTERPRISES v. RAIMONDO

GORSUCH, J., concurring

ion “must be taken in connection with its immediate con-
text,” In re Ayers, 123 U. S. 443, 488 (1887), and stray “re-
marks” must not be elevated above the written law, see The
Belfast, 7 Wall. 624, 641 (1869); see also, e.g., Trebilcock v.
Wilson, 12 Wall. 687, 692–693 (1872); Mason v. Eldred, 6
Wall. 231, 236–238 (1868). During Chief Justice Chase’s
tenure, it seems a Justice writing the Court’s majority opin-
ion would generally work alone and present his work orally
and in summary form to his colleagues at conference, which
meant that other Justices often did not even review the
opinion prior to publication. 6 C. Fairman, History of the
Supreme Court of the United States 69–70 (1971). The
Court could proceed in this way because it understood that
a single judicial opinion may resolve a “case or controversy,”
and in so doing it may make “effective law” for the parties,
but it does not legislate for the whole of the country and is
not to be confused with laws that do.
C
From all this, I see at least three lessons about the doc-
trine of stare decisis relevant to the decision before us today.
Each concerns a form of judicial humility.
First, a past decision may bind the parties to a dispute,
but it provides this Court no authority in future cases to
depart from what the Constitution or laws of the United
States ordain. Instead, the Constitution promises, the
American people are sovereign and they alone may,
through democratically responsive processes, amend our
foundational charter or revise federal legislation. Une-
lected judges enjoy no such power. Part I–B, supra.
Recognizing as much, this Court has often said that stare
decisis is not an “ ‘inexorable command.’ ” State Oil Co. v.
Khan, 522 U. S. 3, 20 (1997). And from time to time it has
found it necessary to correct its past mistakes. When it
comes to correcting errors of constitutional interpretation,
the Court has stressed the importance of doing so, for they

GORSUCH, J., concurring

can be corrected otherwise only through the amendment
process. See, e.g., Franchise Tax Bd. of Cal. v. Hyatt, 587
U. S. 230, 248 (2019). When it comes to fixing errors of stat-
utory interpretation, the Court has proceeded perhaps more
circumspectly. But in that field, too, it has overruled even
longstanding but “flawed” decisions. See, e.g., Leegin Crea-
tive Leather Products, Inc. v. PSKS, Inc., 551 U. S. 877, 904,
907 (2007).
Recent history illustrates all this. During the tenures of
Chief Justices Warren and Burger, it seems this Court over-
ruled an average of around three cases per Term, including
roughly 50 statutory precedents between the 1960s and
1980s alone. See W. Eskridge, Overruling Statutory Prec-
edents, 76 Geo. L. J. 1361, 1427–1434 (1988) (collecting
cases). Many of these decisions came in settings no less
consequential than today’s. In recent years, we have not
approached the pace set by our predecessors, overruling an
average of just one or two prior decisions each Term.1 But
the point remains: Judicial decisions inconsistent with the
written law do not inexorably control.
Second, another lesson tempers the first. While judicial
decisions may not supersede or revise the Constitution or
federal statutory law, they merit our “respect as embodying
the considered views of those who have come before.” Ra-
mos v. Louisiana, 590 U. S. 83, 105 (2020). As a matter of
professional responsibility, a judge must not only avoid con-
fusing his writings with the law. When a case comes before
him, he must also weigh his view of what the law demands
against the thoughtful views of his predecessors. After all,
“[p]recedent is a way of accumulating and passing down the
learning of past generations, a font of established wisdom

richer than what can be found in any single judge or panel
of judges.” Precedent 9.
Doubtless, past judicial decisions may, as they always
have, command “greater or less authority as precedents, ac-
cording to circumstances.” Lincoln Speech 401. But, like
English judges before us, we have long turned to familiar
considerations to guide our assessment of the weight due a
past decision. So, for example, as this Court has put it, the
weight due a precedent may depend on the quality of its
reasoning, its consistency with related decisions, its worka-
