CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
                  THE NINTH CIRCUIT

   No. 18–587.      Argued November 12, 2019—Decided June 18, 2020*
In 2012, the Department of Homeland Security (DHS) issued a memo-
  randum announcing an immigration relief program known as Deferred
  Action for Childhood Arrivals (DACA), which allows certain unauthor-
  ized aliens who arrived in the United States as children to apply for a
  two-year forbearance of removal. Those granted such relief become
  eligible for work authorization and various federal benefits. Some
  700,000 aliens have availed themselves of this opportunity.
     Two years later, DHS expanded DACA eligibility and created a re-
  lated program known as Deferred Action for Parents of Americans and
  Lawful Permanent Residents (DAPA). If implemented, that program
  would have made 4.3 million parents of U. S. citizens or lawful perma-
  nent residents eligible for the same forbearance from removal, work
  eligibility, and other benefits as DACA recipients. Texas, joined by 25
  other States, secured a nationwide preliminary injunction barring im-
  plementation of both the DACA expansion and DAPA. The Fifth Cir-
  cuit upheld the injunction, concluding that the program violated the
  Immigration and Nationality Act (INA), which carefully defines eligi-
  bility for benefits. This Court affirmed by an equally divided vote, and

    the litigation then continued in the District Court.
       In June 2017, following a change in Presidential administrations,
    DHS rescinded the DAPA Memorandum, citing, among other reasons,
    the ongoing suit by Texas and new policy priorities. That September,
    the Attorney General advised Acting Secretary of Homeland Security
    Elaine C. Duke that DACA shared DAPA’s legal flaws and should also
    be rescinded. The next day, Duke acted on that advice. Taking into
    consideration the Fifth Circuit and Supreme Court rulings and the At-
    torney General’s letter, Duke decided to terminate the program. She
    explained that DHS would no longer accept new applications, but that
    existing DACA recipients whose benefits were set to expire within six
    months could apply for a two-year renewal. For all other DACA recip-
    ients, previously issued grants of relief would expire on their own
    terms, with no prospect for renewal.
       Several groups of plaintiffs challenged Duke’s decision to rescind
    DACA, claiming that it was arbitrary and capricious in violation of the
    Administrative Procedure Act (APA) and infringed the equal protec-
    tion guarantee of the Fifth Amendment’s Due Process Clause. District
    Courts in California (Regents, No. 18–587), New York (Batalla Vidal,
    No. 18–589), and the District of Columbia (NAACP, No. 18–588) all
    ruled for the plaintiffs. Each court rejected the Government’s argu-
    ments that the claims were unreviewable under the APA and that the
    INA deprived the courts of jurisdiction. In Regents and Batalla Vidal,
    the District Courts further held that the equal protection claims were
    adequately alleged, and they entered coextensive nationwide prelimi-
    nary injunctions based on the conclusion that the plaintiffs were likely
    to succeed on their APA claims. The District Court in NAACP took a
    different approach. It deferred ruling on the equal protection chal-
    lenge but granted partial summary judgment to the plaintiffs on their
    APA claim, finding that the rescission was inadequately explained.
    The court then stayed its order for 90 days to permit DHS to reissue a
    memorandum rescinding DACA, this time with a fuller explanation of
    the conclusion that DACA was unlawful. Two months later, Duke’s
    successor, Secretary Kirstjen M. Nielsen, responded to the court’s or-
    der. She declined to disturb or replace Duke’s rescission decision and
    instead explained why she thought her predecessor’s decision was
    sound. In addition to reiterating the illegality conclusion, she offered
    several new justifications for the rescission. The Government moved
    for the District Court to reconsider in light of this additional explana-
    tion, but the court concluded that the new reasoning failed to elaborate
    meaningfully on the illegality rationale.
       The Government appealed the various District Court decisions to
    the Second, Ninth, and D. C. Circuits, respectively. While those ap-
    peals were pending, the Government filed three petitions for certiorari

  before judgment. Following the Ninth Circuit affirmance in Regents,
  this Court granted certiorari.
Held: The judgment in No. 18–587 is vacated in part and reversed in
 part; the judgment in No. 18–588 is affirmed; the February 13, 2018
 order in No. 18–589 is vacated, the November 9, 2017 order is affirmed
 in part, and the March 29, 2018 order is reversed in part; and all of the
 cases are remanded.
No. 18–587, 908 F. 3d 476, vacated in part and reversed in part; No. 18–
 588, affirmed; and No. 18–589, February 13, 2018 order vacated, No-
 vember 9, 2017 order affirmed in part, and March 29, 2018 order re-
 versed in part; all cases remanded.
    THE CHIEF JUSTICE delivered the opinion of the Court, except as to
 Part IV, concluding:
    1. DHS’s rescission decision is reviewable under the APA and is
 within this Court’s jurisdiction. Pp. 9–13.
       (a) The APA’s “basic presumption of judicial review” of agency ac-
 tion, Abbott Laboratories v. Gardner, 387 U. S. 136, 140, can be rebut-
 ted by showing that the “agency action is committed to agency discre-
 tion by law,” 5 U. S. C. §701(a)(2). In Heckler v. Chaney, the Court held
 that this narrow exception includes an agency’s decision not to insti-
 tute an enforcement action. 470 U. S. 821, 831–832. The Government
 contends that DACA is a general non-enforcement policy equivalent to
 the individual non-enforcement decision in Chaney. But the DACA
 Memorandum did not merely decline to institute enforcement proceed-
 ings; it created a program for conferring affirmative immigration re-
 lief. Therefore, unlike the non-enforcement decision in Chaney,
 DACA’s creation—and its rescission—is an “action [that] provides a
 focus for judicial review.” Id., at 832. In addition, by virtue of receiving
 deferred action, 700,000 DACA recipients may request work authori-
 zation and are eligible for Social Security and Medicare. Access to such
 benefits is an interest “courts often are called upon to protect.” Ibid.
 DACA’s rescission is thus subject to review under the APA. Pp. 9–12.
       (b) The two jurisdictional provisions of the INA invoked by the
 Government do not apply. Title 8 U. S. C. §1252(b)(9), which bars re-
 view of claims arising from “action[s]” or “proceeding[s] brought to re-
 move an alien,” is inapplicable where, as here, the parties do not chal-
 lenge any removal proceedings. And the rescission is not a decision “to
 commence proceedings, adjudicate cases, or execute removal orders”
 within the meaning of §1252(g). Pp. 12–13.
    2. DHS’s decision to rescind DACA was arbitrary and capricious un-
 der the APA. Pp. 13–26.
       (a) In assessing the rescission, the Government urges the Court to
 consider not just the contemporaneous explanation offered by Acting
 Secretary Duke but also the additional reasons supplied by Secretary
4             DEPARTMENT OF HOMELAND SECURITY v.
                    REGENTS OF UNIV. OF CAL.
                            Syllabus

    Nielsen nine months later. Judicial review of agency action, however,
    is limited to “the grounds that the agency invoked when it took the
    action.” Michigan v. EPA, 576 U. S. 743, 758. If those grounds are
    inadequate, a court may remand for the agency to offer “a fuller expla-
    nation of the agency’s reasoning at the time of the agency action,” Pen-
    sion Benefit Guaranty Corporation v. LTV Corp., 496 U. S. 633, 654
    (emphasis added), or to “deal with the problem afresh” by taking new
    agency action, SEC v. Chenery Corp., 332 U. S. 194, 201. Because Sec-
    retary Nielsen chose not to take new action, she was limited to elabo-
    rating on the agency’s original reasons. But her reasoning bears little
    relationship to that of her predecessor and consists primarily of imper-
    missible “post hoc rationalization.” Citizens to Preserve Overton Park,
    Inc. v. Volpe, 401 U. S. 402, 420. The rule requiring a new decision
    before considering new reasons is not merely a formality. It serves
    important administrative law values by promoting agency accounta-
    bility to the public, instilling confidence that the reasons given are not
    simply convenient litigating positions, and facilitating orderly review.
    Each of these values would be markedly undermined if this Court al-
    lowed DHS to rely on reasons offered nine months after the rescission
    and after three different courts had identified flaws in the original ex-
    planation. Pp. 13–17.
          (b) Acting Secretary Duke’s rescission memorandum failed to con-
    sider important aspects of the problem before the agency. Although
    Duke was bound by the Attorney General’s determination that DACA
    is illegal, see 8 U. S. C. §1103(a)(1), deciding how best to address that
    determination involved important policy choices reserved for DHS.
    Acting Secretary Duke plainly exercised such discretionary authority
    in winding down the program, but she did not appreciate the full scope
    of her discretion. The Attorney General concluded that the legal de-
    fects in DACA mirrored those that the courts had recognized in DAPA.
    The Fifth Circuit, the highest court to offer a reasoned opinion on
    DAPA’s legality, found that DAPA violated the INA because it ex-
    tended eligibility for benefits to a class of unauthorized aliens. But the
    defining feature of DAPA (and DACA) is DHS’s decision to defer re-
    moval, and the Fifth Circuit carefully distinguished that forbearance
    component from the associated benefits eligibility. Eliminating bene-
    fits eligibility while continuing forbearance thus remained squarely
    within Duke’s discretion. Yet, rather than addressing forbearance in
    her decision, Duke treated the Attorney General’s conclusion regard-
    ing the illegality of benefits as sufficient to rescind both benefits and
    forbearance, without explanation. That reasoning repeated the error
    in Motor Vehicle Manufacturers Association of the United States, Inc.
    v. State Farm— treating a rationale that applied to only part of a policy
    as sufficient to rescind the entire policy. 463 U. S. 29, 51. While DHS

  was not required to “consider all policy alternatives,” ibid., deferred
  action was “within the ambit of the existing” policy, ibid.; indeed, it
  was the centerpiece of the policy. In failing to consider the option to
  retain deferred action, Duke “failed to supply the requisite ‘reasoned
  analysis.’ ” Id., at 57.
     That omission alone renders Duke’s decision arbitrary and capri-
  cious, but it was not the only defect. Duke also failed to address
  whether there was “legitimate reliance” on the DACA Memorandum.
  Smiley v. Citibank (South Dakota), N. A., 517 U. S. 735, 742. Certain
  features of the DACA policy may affect the strength of any reliance
  interests, but those features are for the agency to consider in the first
  instance. DHS has flexibility in addressing any reliance interests and
  could have considered various accommodations. While the agency was
  not required to pursue these accommodations, it was required to assess
  the existence and strength of any reliance interests, and weigh them
  against competing policy concerns. Its failure to do so was arbitrary
  and capricious. Pp. 17–26.
     THE CHIEF JUSTICE, joined by JUSTICE GINSBURG, JUSTICE BREYER,
  and JUSTICE KAGAN, concluded in Part IV that respondents’ claims fail
  to establish a plausible inference that the rescission was motivated by
  animus in violation of the equal protection guarantee of the Fifth
  Amendment. Pp. 27–29.

               REGENTS OF UNIV. OF CAL.
                  Opinion of the Court


   CHIEF JUSTICE ROBERTS delivered the opinion of the
Court, except as to Part IV.
   In the summer of 2012, the Department of Homeland Se-
curity (DHS) announced an immigration program known as
Deferred Action for Childhood Arrivals, or DACA. That
program allows certain unauthorized aliens who entered
the United States as children to apply for a two-year for-
bearance of removal. Those granted such relief are also
eligible for work authorization and various federal benefits.
Some 700,000 aliens have availed themselves of this
opportunity.
   Five years later, the Attorney General advised DHS to
rescind DACA, based on his conclusion that it was unlaw-
ful. The Department’s Acting Secretary issued a memoran-
dum terminating the program on that basis. The termina-
tion was challenged by affected individuals and third
parties who alleged, among other things, that the Acting
Secretary had violated the Administrative Procedure Act
(APA) by failing to adequately address important factors
bearing on her decision. For the reasons that follow, we
conclude that the Acting Secretary did violate the APA, and
that the rescission must be vacated.
                             I
                             A
  In June 2012, the Secretary of Homeland Security issued
a memorandum announcing an immigration relief program
for “certain young people who were brought to this country
as children.” App. to Pet. for Cert. in No. 18–587, p. 97a
(App. to Pet. for Cert.). Known as DACA, the program ap-
plies to childhood arrivals who were under age 31 in 2012;
have continuously resided here since 2007; are current stu-
dents, have completed high school, or are honorably dis-
charged veterans; have not been convicted of any serious
crimes; and do not threaten national security or public

                      Opinion of the Court

safety. Id., at 98a. DHS concluded that individuals who
meet these criteria warrant favorable treatment under the
immigration laws because they “lacked the intent to violate
the law,” are “productive” contributors to our society, and
“know only this country as home.” Id., at 98a–99a.
   “[T]o prevent [these] low priority individuals from being
removed from the United States,” the DACA Memorandum
instructs Immigration and Customs Enforcement to “exer-
cise prosecutorial discretion[ ] on an individual basis . . . by
deferring action for a period of two years, subject to re-
newal.” Id., at 100a. In addition, it directs U. S. Citizen-
ship and Immigration Services (USCIS) to “accept applica-
tions to determine whether these individuals qualify for
work authorization during this period of deferred action,”
id., at 101a, as permitted under regulations long predating
DACA’s creation, see 8 CFR §274a.12(c)(14) (2012) (permit-
ting work authorization for deferred action recipients who
establish “economic necessity”); 46 Fed. Reg. 25080–25081
(1981) (similar). Pursuant to other regulations, deferred ac-
tion recipients are considered “lawfully present” for pur-
poses of, and therefore eligible to receive, Social Security
and Medicare benefits. See 8 CFR §1.3(a)(4)(vi); 42 CFR
§417.422(h) (2012).
   In November 2014, two years after DACA was promul-
gated, DHS issued a memorandum announcing that it
would expand DACA eligibility by removing the age cap,
shifting the date-of-entry requirement from 2007 to 2010,
and extending the deferred action and work authorization
period to three years. App. to Pet. for Cert. 106a–107a. In
the same memorandum, DHS created a new, related pro-
gram known as Deferred Action for Parents of Americans
and Lawful Permanent Residents, or DAPA. That program
would have authorized deferred action for up to 4.3 million
parents whose children were U. S. citizens or lawful perma-
nent residents. These parents were to enjoy the same for-
bearance, work eligibility, and other benefits as DACA

recipients.
   Before the DAPA Memorandum was implemented, 26
States, led by Texas, filed suit in the Southern District of
Texas. The States contended that DAPA and the DACA
expansion violated the APA’s notice and comment require-
ment, the Immigration and Nationality Act (INA), and the
Executive’s duty under the Take Care Clause of the Consti-
tution. The District Court found that the States were likely
to succeed on the merits of at least one of their claims and
entered a nationwide preliminary injunction barring imple-
mentation of both DAPA and the DACA expansion. See
Texas v. United States, 86 F. Supp. 3d 591, 677–678 (2015).
   A divided panel of the Court of Appeals for the Fifth Cir-
cuit affirmed the preliminary injunction. Texas v. United
States, 809 F. 3d 134, 188 (2015). In opposing the injunc-
tion, the Government argued that the DAPA Memorandum
reflected an unreviewable exercise of the Government’s en-
forcement discretion. The Fifth Circuit majority disagreed.
It reasoned that the deferred action described in the DAPA
Memorandum was “much more than nonenforcement: It
would affirmatively confer ‘lawful presence’ and associated
benefits on a class of unlawfully present aliens.” Id., at 166.
From this, the majority concluded that the creation of the
DAPA program was not an unreviewable action “committed
to agency discretion by law.” Id., at 169 (quoting 5 U. S. C.
§701(a)(2)).
   The majority then upheld the injunction on two grounds.
It first concluded the States were likely to succeed on their
procedural claim that the DAPA Memorandum was a sub-
stantive rule that was required to undergo notice and com-
ment. It then held that the APA required DAPA to be set
aside because the program was “manifestly contrary” to the
INA, which “expressly and carefully provides legal designa-
tions allowing defined classes” to “receive the benefits” as-
sociated with “lawful presence” and to qualify for work

authorization, 809 F. 3d, at 179–181, 186 (internal quota-
tion marks omitted). Judge King dissented.
   This Court affirmed the Fifth Circuit’s judgment by an
equally divided vote, which meant that no opinion was is-
sued. United States v. Texas, 579 U. S. ___ (2016) (per cu-
riam). For the next year, litigation over DAPA and the
DACA expansion continued in the Southern District of
Texas, while implementation of those policies remained
enjoined.
   Then, in June 2017, following a change in Presidential
administrations, DHS rescinded the DAPA Memorandum.
In explaining that decision, DHS cited the preliminary in-
junction and ongoing litigation in Texas, the fact that
DAPA had never taken effect, and the new administration’s
immigration enforcement priorities.
   Three months later, in September 2017, Attorney
General Jefferson B. Sessions III sent a letter to Acting Sec-
retary of Homeland Security Elaine C. Duke, “advis[ing]”
that DHS “should rescind” DACA as well. App. 877. Citing
the Fifth Circuit’s opinion and this Court’s equally divided
affirmance, the Attorney General concluded that DACA
shared the “same legal . . . defects that the courts recog-
nized as to DAPA” and was “likely” to meet a similar fate.
Id., at 878. “In light of the costs and burdens” that a rescis-
sion would “impose[ ] on DHS,” the Attorney General urged
DHS to “consider an orderly and efficient wind-down
process.” Ibid.
   The next day, Duke acted on the Attorney General’s ad-
vice. In her decision memorandum, Duke summarized the
history of the DACA and DAPA programs, the Fifth Circuit
opinion and ensuing affirmance, and the contents of the At-
torney General’s letter. App. to Pet. for Cert. 111a–117a.
“Taking into consideration the Supreme Court’s and the
Fifth Circuit’s rulings” and the “letter from the Attorney
General,” she concluded that the “DACA program should be
terminated.” Id., at 117a.

                  REGENTS OF UNIV. OF CAL.
                     Opinion of the Court

  Duke then detailed how the program would be wound
down: No new applications would be accepted, but DHS
would entertain applications for two-year renewals from
DACA recipients whose benefits were set to expire within
six months. For all other DACA recipients, previously is-
sued grants of deferred action and work authorization
would not be revoked but would expire on their own terms,
with no prospect for renewal. Id., at 117a–118a.
                               B
   Within days of Acting Secretary Duke’s rescission an-
nouncement, multiple groups of plaintiffs ranging from in-
dividual DACA recipients and States to the Regents of the
University of California and the National Association for
the Advancement of Colored People challenged her decision
in the U. S. District Courts for the Northern District of Cal-
ifornia (Regents, No. 18–587), the Eastern District of New
York (Batalla Vidal, No. 18–589), and the District of Co-
lumbia (NAACP, No. 18–588). The relevant claims are that
the rescission was arbitrary and capricious in violation of
the APA and that it infringed the equal protection guaran-
tee of the Fifth Amendment’s Due Process Clause.1
   All three District Courts ruled for the plaintiffs, albeit at
different stages of the proceedings.2 In doing so, each court
rejected the Government’s threshold arguments that the

——————
  1 Plaintiffs also raised notice and comment claims, which uniformly

failed below, and assorted due process challenges, some of which sur-
vived motions to dismiss. Those claims are not before us.
  2 In a related challenge not at issue here, the District Court for the

District of Maryland granted partial summary judgment in favor of the
Government. Casa de Maryland v. United States Dept. of Homeland Se-
curity, 284 F. Supp. 3d 758 (2018). After the Government filed petitions
for certiorari in the instant cases, the Fourth Circuit reversed that deci-
sion and vacated Acting Secretary Duke’s rescission as arbitrary and ca-
pricious. Casa de Maryland v. United States Dept. of Homeland Security,
924 F. 3d 684 (2019), cert. pending, No. 18–1469. The Fourth Circuit has
since stayed its mandate.

claims were unreviewable under the APA and that the INA
deprived the court of jurisdiction. 298 F. Supp. 3d 209,
223–224, 234–235 (DC 2018); 279 F. Supp. 3d 1011, 1029–
1033 (ND Cal. 2018); 295 F. Supp. 3d 127, 150, 153–154
(EDNY 2017).
   In Regents and Batalla Vidal, the District Courts held
that the equal protection claims were adequately alleged.
298 F. Supp. 3d 1304, 1315 (ND Cal. 2018); 291 F. Supp. 3d
260, 279 (EDNY 2018). Those courts also entered coexten-
sive nationwide preliminary injunctions, based on the con-
clusion that the plaintiffs were likely to succeed on the mer-
its of their claims that the rescission was arbitrary and
capricious. These injunctions did not require DHS to accept
new applications, but did order the agency to allow DACA
recipients to “renew their enrollments.” 279 F. Supp. 3d, at
1048; see 279 F. Supp. 3d 401, 437 (EDNY 2018).
   In NAACP, the D. C. District Court took a different
course. In April 2018, it deferred ruling on the equal pro-
tection challenge but granted partial summary judgment to
the plaintiffs on their APA claim, holding that Acting Sec-
retary Duke’s “conclusory statements were insufficient to
explain the change in [the agency’s] view of DACA’s lawful-
ness.” 298 F. Supp. 3d, at 243. The District Court stayed
its order for 90 days to permit DHS to “reissue a memoran-
dum rescinding DACA, this time providing a fuller expla-
nation for the determination that the program lacks statu-
tory and constitutional authority.” Id., at 245.
   Two months later, Duke’s successor, Secretary Kirstjen
M. Nielsen, responded via memorandum. App. to Pet. for
Cert. 120a–126a. She explained that, “[h]aving considered
the Duke memorandum,” she “decline[d] to disturb” the re-
scission. Id., at 121a. Secretary Nielsen went on to articu-
late her “understanding” of Duke’s memorandum, identify-
ing three reasons why, in Nielsen’s estimation, “the
decision to rescind the DACA policy was, and remains,
sound.” Ibid. First, she reiterated that, “as the Attorney
8         DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                   Opinion of the Court

General concluded, the DACA policy was contrary to law.”
Id., at 122a. Second, she added that, regardless, the agency
had “serious doubts about [DACA’s] legality” and, for law
enforcement reasons, wanted to avoid “legally questiona-
ble” policies. Id., at 123a. Third, she identified multiple
policy reasons for rescinding DACA, including (1) the belief
that any class-based immigration relief should come from
Congress, not through executive non-enforcement; (2)
DHS’s preference for exercising prosecutorial discretion on
“a truly individualized, case-by-case basis”; and (3) the im-
portance of “project[ing] a message” that immigration laws
would be enforced against all classes and categories of al-
iens. Id., at 123a–124a. In her final paragraph, Secretary
Nielsen acknowledged the “asserted reliance interests” in
DACA’s continuation but concluded that they did not “out-
weigh the questionable legality of the DACA policy and the
other reasons” for the rescission discussed in her memoran-
dum. Id., at 125a.
   The Government asked the D. C. District Court to revise
its prior order in light of the reasons provided by Secretary
Nielsen, but the court declined. In the court’s view, the new
memorandum, which “fail[ed] to elaborate meaningfully”
on the agency’s illegality rationale, still did not provide an
adequate explanation for the September 2017 rescission.
315 F. Supp. 3d 457, 460, 473–474 (2018).
   The Government appealed the various District Court de-
cisions to the Second, Ninth, and D. C. Circuits, respec-
tively. In November 2018, while those appeals were pend-
ing, the Government simultaneously filed three petitions
for certiorari before judgment. After the Ninth Circuit af-
firmed the nationwide injunction in Regents, see 908 F. 3d
476 (2018), but before rulings from the other two Circuits,
we granted the petitions and consolidated the cases for ar-
gument. 588 U. S. ___ (2019). The issues raised here are
(1) whether the APA claims are reviewable, (2) if so,
                  Cite as: 591 U. S. ____ (2020)            9

                      Opinion of the Court

whether the rescission was arbitrary and capricious in vio-
lation of the APA, and (3) whether the plaintiffs have stated
an equal protection claim.
                              II
   The dispute before the Court is not whether DHS may
rescind DACA. All parties agree that it may. The dispute
is instead primarily about the procedure the agency fol-
lowed in doing so.
   The APA “sets forth the procedures by which federal
agencies are accountable to the public and their actions
subject to review by the courts.” Franklin v. Massachusetts,
505 U. S. 788, 796 (1992). It requires agencies to engage in
“reasoned decisionmaking,” Michigan v. EPA, 576 U. S.
743, 750 (2015) (internal quotation marks omitted), and di-
rects that agency actions be “set aside” if they are “arbi-
trary” or “capricious,” 5 U. S. C. §706(2)(A). Under this
“narrow standard of review, . . . a court is not to substitute
its judgment for that of the agency,” FCC v. Fox Television
Stations, Inc., 556 U. S. 502, 513 (2009) (internal quotation
marks omitted), but instead to assess only whether the de-
cision was “based on a consideration of the relevant factors
and whether there has been a clear error of judgment,” Cit-
izens to Preserve Overton Park, Inc. v. Volpe, 401 U. S. 402,
416 (1971).
   But before determining whether the rescission was arbi-
trary and capricious, we must first address the Govern-
ment’s contentions that DHS’s decision is unreviewable
under the APA and outside this Court’s jurisdiction.
                               A
   The APA establishes a “basic presumption of judicial
review [for] one ‘suffering legal wrong because of agency ac-
tion.’ ” Abbott Laboratories v. Gardner, 387 U. S. 136, 140
(1967) (quoting §702). That presumption can be rebutted
by a showing that the relevant statute “preclude[s]” review,
10        DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                   Opinion of the Court

§701(a)(1), or that the “agency action is committed to
agency discretion by law,” §701(a)(2). The latter exception
is at issue here.
   To “honor the presumption of review, we have read the
exception in §701(a)(2) quite narrowly,” Weyerhaeuser Co.
v. United States Fish and Wildlife Serv., 586 U. S. ___, ___
(2018) (slip op., at 12), confining it to those rare “adminis-
trative decision[s] traditionally left to agency discretion,”
Lincoln v. Vigil, 508 U. S. 182, 191 (1993). This limited cat-
egory of unreviewable actions includes an agency’s decision
not to institute enforcement proceedings, Heckler v.
Chaney, 470 U. S. 821, 831–832 (1985), and it is on that ex-
ception that the Government primarily relies.
   In Chaney, several death-row inmates petitioned the
Food and Drug Administration (FDA) to take enforcement
action against two States to prevent their use of certain
drugs for lethal injection. The Court held that the FDA’s
denial of that petition was presumptively unreviewable in
light of the well-established “tradition” that “an agency’s
decision not to prosecute or enforce” is “generally commit-
ted to an agency’s absolute discretion.” Id., at 831. We
identified a constellation of reasons that underpin this tra-
dition. To start, a non-enforcement decision “often involves
a complicated balancing of a number of factors which
are peculiarly within [the agency’s] expertise,” such as
“whether the particular enforcement action requested best
fits the agency’s overall policies.” Ibid. The decision also
mirrors, “to some extent,” a prosecutor’s decision not to in-
dict, which has “long been regarded as the special province
of the Executive Branch.” Id., at 832. And, as a practical
matter, “when an agency refuses to act” there is no action
to “provide[ ] a focus for judicial review.” Ibid.
   The Government contends that a general non-enforcement
policy is equivalent to the individual non-enforcement
decision at issue in Chaney. In each case, the Government
argues, the agency must balance factors peculiarly within
                  Cite as: 591 U. S. ____ (2020)            11

                      Opinion of the Court

its expertise, and does so in a manner akin to a criminal
prosecutor. Building on that premise, the Government ar-
gues that the rescission of a non-enforcement policy is no
different—for purposes of reviewability—from the adoption
of that policy. While the rescission may lead to increased
enforcement, it does not, by itself, constitute a particular
enforcement action. Applying this logic to the facts here,
the Government submits that DACA is a non-enforcement
policy and that its rescission is therefore unreviewable.
   But we need not test this chain of reasoning because
DACA is not simply a non-enforcement policy. For starters,
the DACA Memorandum did not merely “refus[e] to insti-
tute proceedings” against a particular entity or even a par-
ticular class. Ibid. Instead, it directed USCIS to “establish
a clear and efficient process” for identifying individuals who
met the enumerated criteria. App. to Pet. for Cert. 100a.
Based on this directive, USCIS solicited applications from
eligible aliens, instituted a standardized review process,
and sent formal notices indicating whether the alien would
receive the two-year forbearance. These proceedings are ef-
fectively “adjudicat[ions].” Id., at 117a. And the result of
these adjudications—DHS’s decision to “grant deferred ac-
tion,” Brief for Petitioners 45—is an “affirmative act of ap-
proval,” the very opposite of a “refus[al] to act,” Chaney, 470
U. S., at 831–832. In short, the DACA Memorandum does
not announce a passive non-enforcement policy; it created
a program for conferring affirmative immigration relief.
The creation of that program—and its rescission—is an “ac-
tion [that] provides a focus for judicial review.” Id., at 832.
   The benefits attendant to deferred action provide
further confirmation that DACA is more than simply a
non-enforcement policy. As described above, by virtue of
receiving deferred action, the 700,000 DACA recipients may
request work authorization and are eligible for Social Secu-
rity and Medicare. See supra, at 3. Unlike an agency’s re-
fusal to take requested enforcement action, access to these
12        DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.

types of benefits is an interest “courts often are called upon
to protect.” Chaney, 470 U. S., at 832. See also Barnhart v.
Thomas, 540 U. S. 20 (2003) (reviewing eligibility determi-
nation for Social Security benefits).
  Because the DACA program is more than a non-enforce-
ment policy, its rescission is subject to review under the
APA.
                               B
   The Government also invokes two jurisdictional provi-
sions of the INA as independent bars to review. Neither
applies.
   Section 1252(b)(9) bars review of claims arising from “ac-
tion[s]” or “proceeding[s] brought to remove an alien.” 66
Stat. 209, as amended, 8 U. S. C. §1252(b)(9). That tar-
geted language is not aimed at this sort of case. As we have
said before, §1252(b)(9) “does not present a jurisdictional
bar” where those bringing suit “are not asking for review of
an order of removal,” “the decision . . . to seek removal,” or
“the process by which . . . removability will be determined.”
Jennings v. Rodriguez, 583 U. S. ___, ___–___ (2018) (plu-
rality opinion) (slip op., at 10–11); id., at ___ (BREYER, J.,
dissenting) (slip op., at 31). And it is certainly not a bar
where, as here, the parties are not challenging any removal
proceedings.
   Section 1252(g) is similarly narrow. That provision limits
review of cases “arising from” decisions “to commence pro-
ceedings, adjudicate cases, or execute removal orders.”
§1252(g). We have previously rejected as “implausible” the
Government’s suggestion that §1252(g) covers “all claims
arising from deportation proceedings” or imposes “a general
jurisdictional limitation.” Reno v. American-Arab Anti-
Discrimination Comm., 525 U. S. 471, 482 (1999). The re-
scission, which revokes a deferred action program with as-
sociated benefits, is not a decision to “commence proceed-
ings,” much less to “adjudicate” a case or “execute” a

removal order.
  With these preliminary arguments out of the way, we
proceed to the merits.

                                A
   Deciding whether agency action was adequately ex-
plained requires, first, knowing where to look for the
agency’s explanation. The natural starting point here is the
explanation provided by Acting Secretary Duke when she
announced the rescission in September 2017. But the Gov-
ernment urges us to go on and consider the June 2018 mem-
orandum submitted by Secretary Nielsen as well. That
memo was prepared after the D. C. District Court vacated
the Duke rescission and gave DHS an opportunity to “reis-
sue a memorandum rescinding DACA, this time providing
a fuller explanation for the determination that the program
lacks statutory and constitutional authority.” 298 F. Supp.
3d, at 245. According to the Government, the Nielsen Mem-
orandum is properly before us because it was invited by the
District Court and reflects the views of the Secretary of
Homeland Security—the official responsible for immigra-
tion policy. Respondents disagree, arguing that the Nielsen
Memorandum, issued nine months after the rescission, im-
permissibly asserts prudential and policy reasons not relied
upon by Duke.
   It is a “foundational principle of administrative law” that
judicial review of agency action is limited to “the grounds
that the agency invoked when it took the action.” Michigan,
576 U. S., at 758. If those grounds are inadequate, a court
may remand for the agency to do one of two things: First,
the agency can offer “a fuller explanation of the agency’s
reasoning at the time of the agency action.” Pension Benefit
Guaranty Corporation v. LTV Corp., 496 U. S. 633, 654
(1990) (emphasis added). See also Alpharma, Inc. v.
14        DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                   Opinion of the Court

Leavitt, 460 F. 3d 1, 5–6 (CADC 2006) (Garland, J.) (per-
mitting an agency to provide an “amplified articulation” of
a prior “conclusory” observation (internal quotation marks
omitted)). This route has important limitations. When an
agency’s initial explanation “indicate[s] the determinative
reason for the final action taken,” the agency may elaborate
later on that reason (or reasons) but may not provide new
ones. Camp v. Pitts, 411 U. S. 138, 143 (1973) (per curiam).
Alternatively, the agency can “deal with the problem
afresh” by taking new agency action. SEC v. Chenery Corp.,
332 U. S. 194, 201 (1947) (Chenery II). An agency taking
this route is not limited to its prior reasons but must comply
with the procedural requirements for new agency action.
   The District Court’s remand thus presented DHS with a
choice: rest on the Duke Memorandum while elaborating on
its prior reasoning, or issue a new rescission bolstered by
new reasons absent from the Duke Memorandum. Secre-
tary Nielsen took the first path. Rather than making a new
decision, she “decline[d] to disturb the Duke memoran-
dum’s rescission” and instead “provide[d] further explana-
tion” for that action. App. to Pet. for Cert. 121a. Indeed,
the Government’s subsequent request for reconsideration
described the Nielsen Memorandum as “additional expla-
nation for [Duke’s] decision” and asked the District Court
to “leave in place [Duke’s] September 5, 2017 decision to re-
scind the DACA policy.” Motion to Revise Order in No. 17–
cv–1907 etc. (D DC), pp. 2, 19. Contrary to the position of
the Government before this Court, and of JUSTICE
KAVANAUGH in dissent, post, at 4 (opinion concurring in
judgment in part and dissenting in part), the Nielsen Mem-
orandum was by its own terms not a new rule implementing
a new policy.
   Because Secretary Nielsen chose to elaborate on the rea-
sons for the initial rescission rather than take new admin-
istrative action, she was limited to the agency’s original rea-
sons, and her explanation “must be viewed critically” to
                   Cite as: 591 U. S. ____ (2020)             15

                       Opinion of the Court

ensure that the rescission is not upheld on the basis of im-
permissible “post hoc rationalization.” Overton Park, 401
U. S., at 420. But despite purporting to explain the Duke
Memorandum, Secretary Nielsen’s reasoning bears little
relationship to that of her predecessor. Acting Secretary
Duke rested the rescission on the conclusion that DACA is
unlawful. Period. See App. to Pet. for Cert. 117a. By con-
trast, Secretary Nielsen’s new memorandum offered three
“separate and independently sufficient reasons” for the re-
scission, id., at 122a, only the first of which is the conclusion
that DACA is illegal.
   Her second reason is that DACA is, at minimum, legally
questionable and should be terminated to maintain public
confidence in the rule of law and avoid burdensome litiga-
tion. No such justification can be found in the Duke Mem-
orandum. Legal uncertainty is, of course, related to illegal-
ity. But the two justifications are meaningfully distinct,
especially in this context. While an agency might, for one
reason or another, choose to do nothing in the face of uncer-
tainty, illegality presumably requires remedial action of
some sort.
   The policy reasons that Secretary Nielsen cites as a third
basis for the rescission are also nowhere to be found in the
Duke Memorandum. That document makes no mention of
a preference for legislative fixes, the superiority of case-by-
case decisionmaking, the importance of sending a message
of robust enforcement, or any other policy consideration.
Nor are these points included in the legal analysis from the
Fifth Circuit and the Attorney General. They can be viewed
only as impermissible post hoc rationalizations and thus
are not properly before us.
   The Government, echoed by JUSTICE KAVANAUGH, pro-
tests that requiring a new decision before considering Niel-
sen’s new justifications would be “an idle and useless for-
mality.” NLRB v. Wyman-Gordon Co., 394 U. S. 759, 766,
16        DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                   Opinion of the Court

n. 6 (1969) (plurality opinion). See also post, at 5. Proce-
dural requirements can often seem such. But here the rule
serves important values of administrative law. Requiring
a new decision before considering new reasons promotes
“agency accountability,” Bowen v. American Hospital Assn.,
476 U. S. 610, 643 (1986), by ensuring that parties and the
public can respond fully and in a timely manner to an
agency’s exercise of authority. Considering only contempo-
raneous explanations for agency action also instills confi-
dence that the reasons given are not simply “convenient lit-
igating position[s].” Christopher v. SmithKline Beecham
Corp., 567 U. S. 142, 155 (2012) (internal quotation marks
omitted). Permitting agencies to invoke belated justifica-
tions, on the other hand, can upset “the orderly functioning
of the process of review,” SEC v. Chenery Corp., 318 U. S.
80, 94 (1943), forcing both litigants and courts to chase a
moving target. Each of these values would be markedly un-
dermined were we to allow DHS to rely on reasons offered
nine months after Duke announced the rescission and after
three different courts had identified flaws in the original
explanation.
   JUSTICE KAVANAUGH asserts that this “foundational
principle of administrative law,” Michigan, 576 U. S., at
758, actually limits only what lawyers may argue, not what
agencies may do. Post, at 5. While it is true that the Court
has often rejected justifications belatedly advanced by ad-
vocates, we refer to this as a prohibition on post hoc ration-
alizations, not advocate rationalizations, because the prob-
lem is the timing, not the speaker. The functional reasons
for requiring contemporaneous explanations apply with
equal force regardless whether post hoc justifications are
raised in court by those appearing on behalf of the agency
or by agency officials themselves. See American Textile
Mfrs. Institute, Inc. v. Donovan, 452 U. S. 490, 539 (1981)
(“[T]he post hoc rationalizations of the agency . . . cannot
serve as a sufficient predicate for agency action.”); Overton

Park, 401 U. S., at 419 (rejecting “litigation affidavits” from
agency officials as “merely ‘post hoc’ rationalizations”).3
  Justice Holmes famously wrote that “[m]en must turn
square corners when they deal with the Government.” Rock
Island, A. & L. R. Co. v. United States, 254 U. S. 141, 143
(1920). But it is also true, particularly when so much is at
stake, that “the Government should turn square corners in
dealing with the people.” St. Regis Paper Co. v. United
States, 368 U. S. 208, 229 (1961) (Black, J., dissenting). The
basic rule here is clear: An agency must defend its actions
based on the reasons it gave when it acted. This is not the
case for cutting corners to allow DHS to rely upon reasons
absent from its original decision.
                              B
  We turn, finally, to whether DHS’s decision to rescind
DACA was arbitrary and capricious. As noted earlier, Act-
ing Secretary Duke’s justification for the rescission was suc-
cinct: “Taking into consideration” the Fifth Circuit’s conclu-
sion that DAPA was unlawful because it conferred benefits
in violation of the INA, and the Attorney General’s conclu-
sion that DACA was unlawful for the same reason, she
concluded—without elaboration—that the “DACA program
should be terminated.” App. to Pet. for Cert. 117a.4
——————
   3 JUSTICE KAVANAUGH further argues that the contemporaneous expla-

nation requirement applies only to agency adjudications, not rule-
makings. Post, at 5–6 (opinion concurring in judgment in part and dis-
senting in part). But he cites no authority limiting this basic principle—
which the Court regularly articulates in the context of rulemakings—to
adjudications. The Government does not even raise this unheralded ar-
gument.
   4 The Government contends that Acting Secretary Duke also focused

on litigation risk. Although the background section of her memo refer-
ences a letter from the Texas Attorney General threatening to challenge
DACA, the memo never asserts that the rescission was intended to avert
litigation. And, given the Attorney General’s conclusion that the policy
was unlawful—and thus presumably could not be maintained or de-
fended in its current form—it is difficult to see how the risk of litigation
18         DEPARTMENT OF HOMELAND SECURITY v.
                 REGENTS OF UNIV. OF CAL.
                    Opinion of the Court

   Respondents maintain that this explanation is deficient
for three reasons. Their first and second arguments work
in tandem, claiming that the Duke Memorandum does not
adequately explain the conclusion that DACA is unlawful,
and that this conclusion is, in any event, wrong. While
those arguments carried the day in the lower courts, in our
view they overlook an important constraint on Acting Sec-
retary Duke’s decisionmaking authority—she was bound by
the Attorney General’s legal determination.
   The same statutory provision that establishes the Secre-
tary of Homeland Security’s authority to administer and en-
force immigration laws limits that authority, specifying
that, with respect to “all questions of law,” the determina-
tions of the Attorney General “shall be controlling.” 8
U. S. C. §1103(a)(1). Respondents are aware of this con-
straint. Indeed they emphasized the point in the reviewa-
bility sections of their briefs. But in their merits argu-
ments, respondents never addressed whether or how this
unique statutory provision might affect our review. They
did not discuss whether Duke was required to explain a le-
gal conclusion that was not hers to make. Nor did they dis-
cuss whether the current suits challenging Duke’s rescis-
sion decision, which everyone agrees was within her legal
authority under the INA, are proper vehicles for attacking
the Attorney General’s legal conclusion.
   Because of these gaps in respondents’ briefing, we do not
evaluate the claims challenging the explanation and cor-
rectness of the illegality conclusion. Instead we focus our
attention on respondents’ third argument—that Acting Sec-
retary Duke “failed to consider . . . important aspect[s] of
the problem” before her. Motor Vehicle Mfrs. Assn. of
United States, Inc. v. State Farm Mut. Automobile Ins. Co.,

                         Opinion of the Court

   Whether DACA is illegal is, of course, a legal determina-
tion, and therefore a question for the Attorney General. But
deciding how best to address a finding of illegality moving
forward can involve important policy choices, especially
when the finding concerns a program with the breadth of
DACA. Those policy choices are for DHS.
   Acting Secretary Duke plainly exercised such discretion-
ary authority in winding down the program. See App. to
Pet. for Cert. 117a–118a (listing the Acting Secretary’s de-
cisions on eight transition issues). Among other things, she
specified that those DACA recipients whose benefits were
set to expire within six months were eligible for two-year
renewals. Ibid.
   But Duke did not appear to appreciate the full scope of
her discretion, which picked up where the Attorney Gen-
eral’s legal reasoning left off. The Attorney General con-
cluded that “the DACA policy has the same legal . . . defects
that the courts recognized as to DAPA.” App. 878. So, to
understand those defects, we look to the Fifth Circuit, the
highest court to offer a reasoned opinion on the legality
of DAPA. That court described the “core” issue before it as
the “Secretary’s decision” to grant “eligibility for benefits”—
including work authorization, Social Security, and
Medicare—to unauthorized aliens on “a class-wide basis.”
Texas, 809 F. 3d, at 170; see id., at 148, 184. The Fifth Cir-
cuit’s focus on these benefits was central to every stage of
its analysis. See id., at 155 (standing); id., at 163 (zone of
interest); id., at 164 (applicability of §1252(g)); id., at 166
(reviewability); id., at 176–177 (notice and comment); id., at
184 (substantive APA). And the Court ultimately held that
DAPA was “manifestly contrary to the INA” precisely be-
cause it “would make 4.3 million otherwise removable al-
iens” eligible for work authorization and public benefits.
Id., at 181–182 (internal quotation marks omitted).5

 5 As the Fifth Circuit noted, DAPA recipients were eligible for Social
20          DEPARTMENT OF HOMELAND SECURITY v.
                  REGENTS OF UNIV. OF CAL.
                     Opinion of the Court

   But there is more to DAPA (and DACA) than such bene-
fits. The defining feature of deferred action is the decision
to defer removal (and to notify the affected alien of that de-
cision). See App. to Pet. for Cert. 99a. And the Fifth Circuit
was careful to distinguish that forbearance component from
eligibility for benefits. As it explained, the “challenged por-
tion of DAPA’s deferred-action program” was the decision
to make DAPA recipients eligible for benefits. See Texas,
809 F. 3d, at 168, and n. 108. The other “[p]art of DAPA,”
the court noted, “involve[d] the Secretary’s decision—at
least temporarily—not to enforce the immigration laws as
to a class of what he deem[ed] to be low-priority illegal al-
iens.” Id., at 166. Borrowing from this Court’s prior de-
scription of deferred action, the Fifth Circuit observed that
“the states do not challenge the Secretary’s decision to ‘de-
cline to institute proceedings, terminate proceedings, or de-
cline to execute a final order of deportation.’ ” Id., at 168
(quoting Reno, 525 U. S., at 484). And the Fifth Circuit un-
derscored that nothing in its decision or the preliminary in-
junction “requires the Secretary to remove any alien or to
alter” the Secretary’s class-based “enforcement priorities.”
Texas, 809 F. 3d, at 166, 169. In other words, the Secre-
tary’s forbearance authority was unimpaired.
   Acting Secretary Duke recognized that the Fifth Circuit’s
holding addressed the benefits associated with DAPA. In
her memorandum she explained that the Fifth Circuit con-

——————
Security and Medicare benefits because they had been designated “law-
fully present.” Texas, 809 F. 3d, at 168. Lawful presence is a statutory
prerequisite for receipt of certain benefits. See id., at 148 (citing 8
U. S. C. §1611). It is not the same as forbearance nor does it flow inexo-
rably from forbearance. Thus, while deferred action recipients have been
designated lawfully present for purposes of Social Security and Medicare
eligibility, see 8 CFR §1.3; 42 CFR §417.422(h), agencies can also exclude
them from this designation, see 45 CFR §152.2(8) (2019) (specifying that
DACA recipients are not considered lawfully present for purposes of cov-
erage under the Affordable Care Act).

                      Opinion of the Court

cluded that DAPA “conflicted with the discretion author-
ized by Congress” because the INA “ ‘flatly does not permit
the reclassification of millions of illegal aliens as lawfully
present and thereby make them newly eligible for a host of
federal and state benefits, including work authorization.’ ”
App. to Pet. for Cert. 114a (quoting Texas, 809 F. 3d, at
184). Duke did not characterize the opinion as one about
forbearance.
   In short, the Attorney General neither addressed the for-
bearance policy at the heart of DACA nor compelled DHS
to abandon that policy. Thus, removing benefits eligibility
while continuing forbearance remained squarely within the
discretion of Acting Secretary Duke, who was responsible
for “[e]stablishing national immigration enforcement poli-
cies and priorities.” 116 Stat. 2178, 6 U. S. C. §202(5). But
Duke’s memo offers no reason for terminating forbearance.
She instead treated the Attorney General’s conclusion re-
garding the illegality of benefits as sufficient to rescind both
benefits and forbearance, without explanation.
   That reasoning repeated the error we identified in one of
our leading modern administrative law cases, Motor Vehicle
Manufacturers Association of the United States, Inc. v. State
Farm Mutual Automobile Insurance Co. There, the Na-
tional Highway Traffic Safety Administration (NHTSA)
promulgated a requirement that motor vehicles produced
after 1982 be equipped with one of two passive restraints:
airbags or automatic seatbelts. 463 U. S., at 37–38, 46.
Four years later, before the requirement went into effect,
NHTSA concluded that automatic seatbelts, the restraint of
choice for most manufacturers, would not provide effective
protection. Based on that premise, NHTSA rescinded the
passive restraint requirement in full. Id., at 38.
   We concluded that the total rescission was arbitrary and
capricious. As we explained, NHTSA’s justification sup-
ported only “disallow[ing] compliance by means of ” auto-
matic seatbelts. Id., at 47. It did “not cast doubt” on the
22         DEPARTMENT OF HOMELAND SECURITY v.
                 REGENTS OF UNIV. OF CAL.
                    Opinion of the Court

“efficacy of airbag technology” or upon “the need for a
passive restraint standard.” Ibid. Given NHTSA’s prior
judgment that “airbags are an effective and cost-beneficial
lifesaving technology,” we held that “the mandatory
passive restraint rule [could] not be abandoned without any
consideration whatsoever of an airbags-only requirement.”
Id., at 51.
   While the factual setting is different here, the error is the
same. Even if it is illegal for DHS to extend work authori-
zation and other benefits to DACA recipients, that conclu-
sion supported only “disallow[ing]” benefits. Id., at 47. It
did “not cast doubt” on the legality of forbearance or upon
DHS’s original reasons for extending forbearance to child-
hood arrivals. Ibid. Thus, given DHS’s earlier judgment
that forbearance is “especially justified” for “productive
young people” who were brought here as children
and “know only this country as home,” App. to Pet. for
Cert. 98a–99a, the DACA Memorandum could not be re-
scinded in full “without any consideration whatsoever” of a
forbearance-only policy, State Farm, 463 U. S., at 51.6
   The Government acknowledges that “[d]eferred action
coupled with the associated benefits are the two legs upon
which the DACA policy stands.” Reply Brief 21. It insists,
however, that “DHS was not required to consider whether
DACA’s illegality could be addressed by separating” the

——————
   6 The three-page memorandum that established DACA is devoted en-

tirely to forbearance, save for one sentence directing USCIS to “deter-
mine whether [DACA recipients] qualify for work authorization.” App.
to Pet. for Cert. 101a. The benefits associated with DACA flow from a
separate regulation. See 8 CFR §1.3(a)(4)(vi); see also 42 CFR
§417.422(h) (cross-referencing 8 CFR §1.3). Thus, DHS could have ad-
dressed the Attorney General’s determination that such benefits were
impermissible under the INA by amending 8 CFR §1.3 to exclude DACA
recipients from those benefits without rescinding the DACA Memoran-
dum and the forbearance policy it established. But Duke’s rescission
memo shows no cognizance of this possibility.

two. Ibid. According to the Government, “It was not arbi-
trary and capricious for DHS to view deferred action and its
collateral benefits as importantly linked.” Ibid. Perhaps.
But that response misses the point. The fact that there may
be a valid reason not to separate deferred action from ben-
efits does not establish that DHS considered that option or
that such consideration was unnecessary.
   The lead dissent acknowledges that forbearance and ben-
efits are legally distinct and can be decoupled. Post, at 21–
22, n. 14 (opinion of THOMAS, J). It contends, however, that
we should not “dissect” agency action “piece by piece.” Post,
at 21. The dissent instead rests on the Attorney General’s
legal determination—which considered only benefits—“to
supply the ‘reasoned analysis’ ” to support rescission of both
benefits and forbearance. Post, at 22 (quoting State Farm,
463 U. S., at 42). But State Farm teaches that when an
agency rescinds a prior policy its reasoned analysis must
consider the “alternative[s]” that are “within the ambit of
the existing [policy].” Id., at 51. Here forbearance was not
simply “within the ambit of the existing [policy],” it was the
centerpiece of the policy: DACA, after all, stands for “De-
ferred Action for Childhood Arrivals.” App. to Pet. for Cert.
111a (emphasis added). But the rescission memorandum
contains no discussion of forbearance or the option of retain-
ing forbearance without benefits. Duke “entirely failed to
consider [that] important aspect of the problem.” State
Farm, 463 U. S., at 43.
   That omission alone renders Acting Secretary Duke’s de-
cision arbitrary and capricious. But it is not the only defect.
Duke also failed to address whether there was “legitimate
reliance” on the DACA Memorandum. Smiley v. Citibank
(South Dakota), N. A., 517 U. S. 735, 742 (1996). When an
agency changes course, as DHS did here, it must “be cogni-
zant that longstanding policies may have ‘engendered seri-
ous reliance interests that must be taken into account.’ ”

                REGENTS OF UNIV. OF CAL.
                   Opinion of the Court

(slip op., at 9) (quoting Fox Television, 556 U. S., at 515). “It
would be arbitrary and capricious to ignore such matters.”
Id., at 515. Yet that is what the Duke Memorandum did.
   For its part, the Government does not contend that Duke
considered potential reliance interests; it counters that she
did not need to. In the Government’s view, shared by the
lead dissent, DACA recipients have no “legally cognizable
reliance interests” because the DACA Memorandum stated
that the program “conferred no substantive rights” and pro-
vided benefits only in two-year increments. Reply Brief 16–
17; App. to Pet. for Cert. 125a. See also post, at 23–24 (opin-
ion of THOMAS, J). But neither the Government nor the lead
dissent cites any legal authority establishing that such fea-
tures automatically preclude reliance interests, and we are
not aware of any. These disclaimers are surely pertinent in
considering the strength of any reliance interests, but that
consideration must be undertaken by the agency in the first
instance, subject to normal APA review. There was no such
consideration in the Duke Memorandum.
   Respondents and their amici assert that there was much
for DHS to consider. They stress that, since 2012, DACA
recipients have “enrolled in degree programs, embarked on
careers, started businesses, purchased homes, and even
married and had children, all in reliance” on the DACA pro-
gram. Brief for Respondent Regents of Univ. of California
et al. in No. 18–587, p. 41 (Brief for Regents). The conse-
quences of the rescission, respondents emphasize, would
“radiate outward” to DACA recipients’ families, including
their 200,000 U. S.-citizen children, to the schools where
DACA recipients study and teach, and to the employers who
have invested time and money in training them. See id., at
41–42; Brief for Respondent State of New York et al. in No.
18–589, p. 42 (Brief for New York). See also Brief for 143
Businesses as Amici Curiae 17 (estimating that hiring and
training replacements would cost employers $6.3 billion).

                      Opinion of the Court

In addition, excluding DACA recipients from the lawful la-
bor force may, they tell us, result in the loss of $215 billion
in economic activity and an associated $60 billion in federal
tax revenue over the next ten years. Brief for Regents 6.
Meanwhile, States and local governments could lose $1.25
billion in tax revenue each year. Ibid.
   These are certainly noteworthy concerns, but they are not
necessarily dispositive. To the Government and lead dis-
sent’s point, DHS could respond that reliance on forbear-
ance and benefits was unjustified in light of the express lim-
itations in the DACA Memorandum. Or it might conclude
that reliance interests in benefits that it views as unlawful
are entitled to no or diminished weight. And, even if DHS
ultimately concludes that the reliance interests rank as se-
rious, they are but one factor to consider. DHS may deter-
mine, in the particular context before it, that other interests
and policy concerns outweigh any reliance interests. Mak-
ing that difficult decision was the agency’s job, but the
agency failed to do it.
   DHS has considerable flexibility in carrying out its re-
sponsibility. The wind-down here is a good example of the
kind of options available. Acting Secretary Duke author-
ized DHS to process two-year renewals for those DACA re-
cipients whose benefits were set to expire within six
months. But Duke’s consideration was solely for the pur-
pose of assisting the agency in dealing with “administrative
complexities.” App. to Pet. for Cert. 116a–118a. She should
have considered whether she had similar flexibility in ad-
dressing any reliance interests of DACA recipients. The
lead dissent contends that accommodating such interests
would be “another exercise of unlawful power,” post, at 23
(opinion of THOMAS, J.), but the Government does not make
that argument and DHS has already extended benefits for
purposes other than reliance, following consultation with
the Office of the Attorney General. App. to Pet. for Cert.
116a.
26        DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                   Opinion of the Court

  Had Duke considered reliance interests, she might, for
example, have considered a broader renewal period based
on the need for DACA recipients to reorder their affairs. Al-
ternatively, Duke might have considered more accommo-
dating termination dates for recipients caught in the mid-
dle of a time-bounded commitment, to allow them to, say,
graduate from their course of study, complete their military
service, or finish a medical treatment regimen. Or she
might have instructed immigration officials to give salient
weight to any reliance interests engendered by DACA when
exercising individualized enforcement discretion.
  To be clear, DHS was not required to do any of this or to
“consider all policy alternatives in reaching [its] decision.”
State Farm, 463 U. S., at 51. Agencies are not compelled to
explore “every alternative device and thought conceivable
by the mind of man.” Vermont Yankee Nuclear Power Corp.
v. Natural Resources Defense Council, Inc., 435 U. S. 519,
551 (1978). But, because DHS was “not writing on a blank
slate,” post, at 22, n. 14 (opinion of THOMAS, J.), it was re-
quired to assess whether there were reliance interests, de-
termine whether they were significant, and weigh any such
interests against competing policy concerns.
   The lead dissent sees all the foregoing differently. In its
view, DACA is illegal, so any actions under DACA are them-
selves illegal. Such actions, it argues, must cease immedi-
ately and the APA should not be construed to impede that
result. See post, at 19–23 (opinion of THOMAS, J.).
   The dissent is correct that DACA was rescinded because
of the Attorney General’s illegality determination. See
ante, at 20. But nothing about that determination fore-
closed or even addressed the options of retaining forbear-
ance or accommodating particular reliance interests. Act-
ing Secretary Duke should have considered those matters
but did not. That failure was arbitrary and capricious in
violation of the APA.

                              IV
   Lastly, we turn to respondents’ claim that the rescis-
sion violates the equal protection guarantee of the Fifth
Amendment.
   The parties dispute the proper framing of this claim. The
Government contends that the allegation that the Execu-
tive, motivated by animus, ended a program that dispropor-
tionately benefits certain ethnic groups is a selective en-
forcement claim. Such a claim, the Government asserts,
is barred by our decision in Reno v. American-Arab Anti-
Discrimination Committee. See 525 U. S., at 488 (holding
that “an alien unlawfully in this country has no constitu-
tional right to assert selective enforcement as a defense
against his deportation”). Respondents counter that their
claim falls outside the scope of that precedent because they
are not challenging individual enforcement proceedings.
We need not resolve this debate because, even if the claim
is cognizable, the allegations here are insufficient.
   To plead animus, a plaintiff must raise a plausible infer-
ence that an “invidious discriminatory purpose was a moti-
vating factor” in the relevant decision. Arlington Heights v.
Metropolitan Housing Development Corp., 429 U. S. 252,
266 (1977). Possible evidence includes disparate impact on
a particular group, “[d]epartures from the normal proce-
dural sequence,” and “contemporary statements by mem-
bers of the decisionmaking body.” Id., at 266–268. Track-
ing these factors, respondents allege that animus is
evidenced by (1) the disparate impact of the rescission on
Latinos from Mexico, who represent 78% of DACA recipi-
ents; (2) the unusual history behind the rescission; and
(3) pre- and post-election statements by President Trump.
Brief for New York 54–55.
   None of these points, either singly or in concert, estab-
lishes a plausible equal protection claim. First, because
Latinos make up a large share of the unauthorized alien
population, one would expect them to make up an outsized
28        DEPARTMENT OF HOMELAND SECURITY v.

share of recipients of any cross-cutting immigration relief
program. See B. Baker, DHS, Office of Immigration Statis-
tics, Population Estimates, Illegal Alien Population
Residing in the United States: January 2015, Table 2 (Dec.
2018), https://www.dhs.gov/sites/default/files/publications/
18_1214_PLCY_pops-est-report.pdf. Were this fact suffi-
cient to state a claim, virtually any generally applicable im-
migration policy could be challenged on equal protection
grounds.
   Second, there is nothing irregular about the history lead-
ing up to the September 2017 rescission. The lower courts
concluded that “DACA received reaffirmation by [DHS] as
recently as three months before the rescission,” 908 F. 3d,
at 519 (quoting 298 F. Supp. 3d, at 1315), referring to the
June 2017 DAPA rescission memo, which stated that DACA
would “remain in effect,” App. 870. But this reasoning con-
fuses abstention with reaffirmation. The DAPA memo did
not address the merits of the DACA policy or its legality.
Thus, when the Attorney General later determined that
DACA shared DAPA’s legal defects, DHS’s decision to
reevaluate DACA was not a “strange about-face.” 908 F. 3d,
at 519. It was a natural response to a newly identified
problem.
   Finally, the cited statements are unilluminating. The
relevant actors were most directly Acting Secretary Duke
and the Attorney General. As the Batalla Vidal court
acknowledged, respondents did not “identif[y] statements
by [either] that would give rise to an inference of discrimi-
natory motive.” 291 F. Supp. 3d, at 278. Instead, respond-
ents contend that President Trump made critical state-
ments about Latinos that evince discriminatory intent.
But, even as interpreted by respondents, these state-
ments—remote in time and made in unrelated contexts—
do not qualify as “contemporary statements” probative of
the decision at issue. Arlington Heights, 429 U. S., at 268.
Thus, like respondents’ other points, the statements fail to
                    Cite as: 591 U. S. ____ (2020)                  29

raise a plausible inference that the rescission was moti-
vated by animus.
                          *    *     *
   We do not decide whether DACA or its rescission are
sound policies. “The wisdom” of those decisions “is none of
our concern.” Chenery II, 332 U. S., at 207. We address
only whether the agency complied with the procedural re-
quirement that it provide a reasoned explanation for its ac-
tion. Here the agency failed to consider the conspicuous is-
sues of whether to retain forbearance and what if anything
to do about the hardship to DACA recipients. That dual
failure raises doubts about whether the agency appreciated
the scope of its discretion or exercised that discretion in a
reasonable manner. The appropriate recourse is therefore
to remand to DHS so that it may consider the problem
anew.
   The judgment in NAACP, No. 18–588, is affirmed.7 The
judgment in Regents, No. 18–587, is vacated in part and re-
versed in part. And in Batalla Vidal, No. 18–589, the Feb-
ruary 13, 2018 order granting respondents’ motion for a
preliminary injunction is vacated, the November 9, 2017 or-
der partially denying the Government’s motion to dismiss
is affirmed in part, and the March 29, 2018 order partially
denying the balance of the Government’s motion to dismiss
is reversed in part. All three cases are remanded for further
proceedings consistent with this opinion.

                                                     It is so ordered.

2         DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                  Opinion of SOTOMAYOR, J.

   The majority rightly holds that the Department of Home-
land Security (DHS) violated the Administrative Procedure
Act in rescinding the Deferred Action for Childhood Arri-
vals (DACA) program. But the Court forecloses any chal-
lenge to the rescission under the Equal Protection Clause.
I believe that determination is unwarranted on the existing
record and premature at this stage of the litigation. I would
instead permit respondents to develop their equal protec-
tion claims on remand.
   Respondents’ equal protection challenges come to us in a
preliminary posture. All that respondents needed to do at
this stage of the litigation was state sufficient facts that
would “allo[w a] court to draw the reasonable inference that
[a] defendant is liable for the misconduct alleged.” Ashcroft
v. Iqbal, 556 U. S. 662, 678 (2009). The three courts to eval-
uate respondents’ pleadings below held that they cleared
this modest threshold. 908 F. 3d 476, 518–520 (CA9 2018)
(affirming the District Court’s denial of the Government’s
motion to dismiss); see also Batalla Vidal v. Nielsen, 291 F.
Supp. 3d 260, 274 (EDNY 2018).
   I too would permit respondents’ claims to proceed on re-
mand. The complaints each set forth particularized facts
that plausibly allege discriminatory animus. The plurality
disagrees, reasoning that “[n]one of these points, either sin-
gly or in concert, establishes a plausible equal protection
claim.” Ante, at 27. But it reaches that conclusion by dis-
counting some allegations altogether and by narrowly view-
ing the rest.
   First, the plurality dismisses the statements that Presi-
dent Trump made both before and after he assumed office.
The Batalla Vidal complaints catalog then-candidate
Trump’s declarations that Mexican immigrants are “people
that have lots of problems,” “the bad ones,” and “criminals,
drug dealers, [and] rapists.” 291 F. Supp. 3d, at 276 (inter-
nal quotation marks omitted). The Regents complaints ad-

ditionally quote President Trump’s 2017 statement compar-
ing undocumented immigrants to “animals” responsible for
“the drugs, the gangs, the cartels, the crisis of smuggling
and trafficking, [and] MS13.” 298 F. Supp. 3d 1304, 1314
(ND Cal. 2018) (internal quotation marks omitted). The
plurality brushes these aside as “unilluminating,” “remote
in time,” and having been “made in unrelated contexts.”
Ante, at 28.
   But “nothing in our precedent supports [the] blinkered
approach” of disregarding any of the campaign statements
as remote in time from later-enacted policies. Trump v. Ha-
waii, 585 U. S. ___, ___, n. 3 (2018) (SOTOMAYOR, J., dis-
senting) (slip op., at 11, n. 3). Nor did any of the statements
arise in unrelated contexts. They bear on unlawful migra-
tion from Mexico—a keystone of President Trump’s cam-
paign and a policy priority of his administration—and, ac-
cording to respondents, were an animating force behind the
rescission of DACA. Cf. ibid. (noting that Presidential Proc-
lamation No. 9645, 82 Fed. Reg. 45161 (2017), which barred
entry of individuals from several Muslim-majority coun-
tries, was an outgrowth of the President’s campaign state-
ments about Muslims). Taken together, “the words of the
President” help to “create the strong perception” that the
rescission decision was “contaminated by impermissible
discriminatory animus.” 585 U. S., at ___ (opinion of
SOTOMAYOR, J.) (slip op., at 13). This perception provides
respondents with grounds to litigate their equal protection
claims further.
   Next, the plurality minimizes the disproportionate im-
pact of the rescission decision on Latinos after considering
this point in isolation. Ante, at 28 (“Were this fact sufficient
to state a claim, virtually any generally applicable immi-
gration policy could be challenged on equal protection
grounds”). But the impact of the policy decision must be
viewed in the context of the President’s public statements
on and off the campaign trail. At the motion-to-dismiss

stage, I would not so readily dismiss the allegation that an
executive decision disproportionately harms the same ra-
cial group that the President branded as less desirable mere
months earlier.
   Finally, the plurality finds nothing untoward in the “spe-
cific sequence of events leading up to the challenged deci-
sion.” Arlington Heights v. Metropolitan Housing Develop-
ment Corp., 429 U. S. 252, 267 (1977). I disagree. As late
as June 2017, DHS insisted it remained committed to
DACA, even while rescinding a related program, the De-
ferred Action for Parents of Americans and Lawful Perma-
nent Residents. App. 718–720. But a mere three months
later, DHS terminated DACA without, as the plurality
acknowledges, considering important aspects of the termi-
nation. The abrupt change in position plausibly suggests
that something other than questions about the legality of
DACA motivated the rescission decision. Accordingly, it
raises the possibility of a “significant mismatch between the
decision . . . made and the rationale . . . provided.” Depart-
ment of Commerce v. New York, 588 U. S. ___, ___ (2019)
(slip op., at 26). Only by bypassing context does the plural-
ity conclude otherwise.
                         *    *     *
   The facts in respondents’ complaints create more than a
“sheer possibility that a defendant has acted unlawfully.”
Iqbal, 556 U. S., at 678. Whether they ultimately amount
to actionable discrimination should be determined only af-
ter factual development on remand. Because the Court
prematurely disposes of respondents’ equal protection
claims by overlooking the strength of their complaints, I
join all but Part IV of the opinion and do not concur in the
corresponding part of the judgment.

   Between 2001 and 2011, Congress considered over two
dozen bills that would have granted lawful status to mil-
lions of aliens who were illegally brought to this country as
children. Each of those legislative efforts failed. In the
wake of this impasse, the Department of Homeland Secu-
rity (DHS) under President Barack Obama took matters
into its own hands. Without any purported delegation of
authority from Congress and without undertaking a rule-
making, DHS unilaterally created a program known as
Deferred Action for Childhood Arrivals (DACA). The three-
page DACA memorandum made it possible for approxi-
mately 1.7 million illegal aliens to qualify for temporary
lawful presence and certain federal and state benefits.
When President Donald Trump took office in 2017, his Act-
ing Secretary of Homeland Security, acting through yet an-
other memorandum, rescinded the DACA memorandum.
To state it plainly, the Trump administration rescinded
DACA the same way that the Obama administration cre-
ated it: unilaterally, and through a mere memorandum.
   Today the majority makes the mystifying determination
that this rescission of DACA was unlawful. In reaching
that conclusion, the majority acts as though it is engaging
in the routine application of standard principles of admin-
istrative law. On the contrary, this is anything but a stand-
ard administrative law case.
   DHS created DACA during the Obama administration
without any statutory authorization and without going
through the requisite rulemaking process. As a result, the
program was unlawful from its inception. The majority
does not even attempt to explain why a court has the au-
thority to scrutinize an agency’s policy reasons for rescind-
ing an unlawful program under the arbitrary and capri-
cious microscope. The decision to countermand an unlawful
agency action is clearly reasonable. So long as the agency’s
determination of illegality is sound, our review should be at
an end.

   Today’s decision must be recognized for what it is: an ef-
fort to avoid a politically controversial but legally correct
decision. The Court could have made clear that the solution
respondents seek must come from the Legislative Branch.
Instead, the majority has decided to prolong DHS’ initial
overreach by providing a stopgap measure of its own. In
doing so, it has given the green light for future political bat-
tles to be fought in this Court rather than where they right-
fully belong—the political branches. Such timidity forsakes
the Court’s duty to apply the law according to neutral prin-
ciples, and the ripple effects of the majority’s error will be
felt throughout our system of self-government.
   Perhaps even more unfortunately, the majority’s holding
creates perverse incentives, particularly for outgoing ad-
ministrations. Under the auspices of today’s decision, ad-
ministrations can bind their successors by unlawfully
adopting significant legal changes through Executive
Branch agency memoranda. Even if the agency lacked au-
thority to effectuate the changes, the changes cannot be un-
done by the same agency in a successor administration un-
less the successor provides sufficient policy justifications to
the satisfaction of this Court. In other words, the majority
erroneously holds that the agency is not only permitted, but
required, to continue administering unlawful programs
that it inherited from a previous administration. I respect-

“prosecutorial discretion” policy known as DACA. App. to
Pet. for Cert. in No. 18–587, p. 97a. The memorandum di-
rected immigration enforcement officers not to remove “cer-
tain young people who were brought to this country as chil-
dren” that met delineated criteria. Id., at 97a–98a. In the
Secretary’s view, the program was consistent with “the
framework of the existing law.” Id., at 101a.
   DACA granted a renewable 2-year period of “deferred ac-
tion” that made approximately 1.7 million otherwise remov-
able aliens eligible to remain in this country temporarily.3
By granting deferred action, the memorandum also made
recipients eligible for certain state and federal benefits, in-
cluding Medicare and Social Security. See 8 U. S. C.

§1324a(h)(3)(B); 8 CFR §274a.12(c)(14). Despite these
changes, the memorandum contradictorily claimed that it
“confer[red] no substantive right [or] immigration status,”
because “[o]nly the Congress, acting through its legislative
authority, can confer these rights.” App. to Pet. for Cert. in
No. 18–587, at 101a.
  In 2014, then-Secretary of Homeland Security Jeh John-
son broadened the deferred-action program in yet another
brief memorandum. This 2014 memorandum expanded
DACA eligibility by extending the deferred-action period to
three years and by relaxing other criteria. It also imple-
mented a related program, known as Deferred Action for
Parents of Americans and Lawful Permanent Residents
(DAPA). DAPA allowed unlawfully present parents to ob-
tain deferred action derivatively through their children who
were either citizens or lawful permanent residents. Ap-
proximately 4.3 million aliens qualified for DAPA and, as
with DACA, these individuals would have become eligible
for certain federal and state benefits upon the approval of
their DAPA applications. See Texas v. United States, 809
F. 3d 134, 181 (CA5 2015). Nevertheless, the 2014 memo-
randum repeated the incongruous assertion that these pro-
grams “d[id] not confer any form of legal status in this coun-
try” and added that deferred action “may be terminated at
any time at the agency’s discretion.” App. to Pet. for Cert.
in No. 18–587, at 104a.

   Twenty-six States filed suit to enjoin the implementation
of these new programs, DAPA and “expanded DACA,”
maintaining that they violated the Constitution, the Ad-
ministrative Procedure Act (APA), and the Immigration
and Naturalization Act (INA). The States contended that,
because the 2014 memorandum allowed aliens to receive
deferred action and other benefits, it amounted to a legisla-
tive rule that had to comply with the APA’s notice and

comment procedures. The States also argued that DHS’ de-
cision to recategorize an entire class of aliens from “unlaw-
fully present” to “lawfully present” exceeded its statutory
authority under the federal immigration laws. According
to the States, these defects rendered the 2014 memoran-
dum arbitrary, capricious, or otherwise not in accordance
with law.
   The District Court preliminarily enjoined DAPA and ex-
panded DACA. The Fifth Circuit affirmed, rejecting DHS’
claim that the programs were an exercise of prosecutorial
discretion. Texas, 809 F. 3d, at 167, 188. The court con-
cluded that the States were likely to succeed on their claim
that the 2014 memorandum was a legislative rule that had
to be adopted through notice and comment rulemaking. Id.,
at 171–178. The court further concluded that the 2014
memorandum was “substantively contrary to law” because
the INA did not grant DHS the statutory authority to im-
plement either program. Id., at 170, 178–186.
   This Court affirmed the Fifth Circuit’s judgment by an
equally divided vote. United States v. Texas, 579 U. S. ___

   The 2014 memorandum was rescinded on June 15, 2017,
before taking effect. Shortly after that rescission, several
of the plaintiff States sent a letter to then-Attorney General
Jefferson Sessions III. They contended that the 2012 DACA
memorandum was also legally defective because, “just like
DAPA, DACA unilaterally confers eligibility for . . . lawful
presence without any statutory authorization from Con-
gress.” App. 873. The States wrote that they would amend
their complaint to challenge DACA if the administration
did not rescind the 2012 memorandum creating DACA by
September 5, 2017.
   On September 4, then-Attorney General Sessions wrote
to then-Acting Secretary of Homeland Security Elaine

Duke, advising her to rescind DACA. Sessions stated that,
in his legal opinion, DACA took effect “through executive
action, without proper statutory authority and with no es-
tablished end-date, after Congress’ repeated rejection of
proposed legislation that would have accomplished a simi-
lar result. Such an open-ended circumvention of immigra-
tion laws was an unconstitutional exercise of authority by
the Executive Branch.” Id., at 877. The letter also stated
that DACA was infected with the “same legal . . . defects
that the courts recognized as to DAPA,” id., at 878, and thus
DACA would likely be enjoined as well.
    Then-Acting Secretary Duke rescinded DACA the next
day, also through a memorandum. Her memorandum be-
gan by noting that DACA “purported to use deferred action
. . . to confer certain benefits to illegal aliens that Congress
had not otherwise acted to provide by law.” App. to Pet. for
Cert. in No. 18–587, at 112a. It described the history of the
Fifth Circuit litigation, noting that the court had concluded
that DAPA “conflicted with the discretion authorized by
Congress” because “the [INA] flatly does not permit the
reclassification of millions of illegal aliens as lawfully pre-
sent.” Id., at 114a (internal quotation marks omitted). Fi-
nally, the memorandum accepted then-Attorney General
Sessions’ legal determination that DACA was unlawful for
the same reasons as DAPA. See §1103(a)(1). In light of the
legal conclusions reached by the Fifth Circuit and the At-
torney General, then-Acting Secretary Duke set forth the
procedures for winding down DACA.
    These three cases soon followed. In each, respondents
claimed, among other things, that DACA’s rescission was
arbitrary and capricious under the APA. Two District
Courts granted a preliminary nationwide injunction, while
the third vacated the rescission.

569 U. S. 290, 317 (2013) (ROBERTS, C. J., dissenting) (quot-
ing Louisiana Pub. Serv. Comm’n v. FCC, 476 U. S. 355,
374 (1986)). When an agency exercises power beyond the
bounds of its authority, it acts unlawfully. See, e.g., SAS
Institute Inc. v. Iancu, 584 U. S. ___, ___, n. (2018) (slip op.,
at 11, n.). The 2012 memorandum creating DACA provides
a poignant illustration of ultra vires agency action.
   DACA alters how the immigration laws apply to a certain
class of aliens. “DACA [recipients] primarily entered the
country either by overstaying a visa or by entering without
inspection, and the INA instructs that aliens in both classes
are removable.” Texas v. United States, 328 F. Supp. 3d
662, 713 (SD Tex. 2018) (footnote omitted). But DACA
granted its recipients deferred action, i.e., a decision to “de-
cline to institute [removal] proceedings, terminate [re-
moval] proceedings, or decline to institute a final order of
[removal].” Reno v. American-Arab Anti-Discrimination
Comm., 525 U. S. 471, 484 (1999) (internal quotation marks
omitted). Under other regulations, recipients of deferred
action are deemed lawfully present for purposes of certain
federal benefits. See supra, at 4. Thus, DACA in effect cre-
ated a new exception to the statutory provisions governing
removability and, in the process, conferred lawful presence
on an entire class of aliens.
   To lawfully implement such changes, DHS needed a
grant of authority from Congress to either reclassify remov-
able DACA recipients as lawfully present, or to exempt the
entire class of aliens covered by DACA from statutory re-
moval procedures. No party disputes that the immigration
statutes lack an express delegation to accomplish either re-
sult. And, an examination of the highly reticulated immi-
gration regime makes clear that DHS has no implicit dis-
cretion to create new classes of lawful presence or to grant
relief from removal out of whole cloth. Accordingly, DACA
is substantively unlawful.

  This conclusion should begin and end our review. The
decision to rescind an unlawful agency action is per se law-
ful. No additional policy justifications or considerations are
necessary. And, the majority’s contrary holding—that an
agency is not only permitted, but required, to continue an
ultra vires action—has no basis in law.
                              A
  Congress has not authorized DHS to reclassify an entire
class of removable aliens as lawfully present or to categori-
cally exempt aliens from statutory removal provisions.
                               1
  I begin with lawful presence. As just stated, nothing in
the federal immigration laws expressly delegates to DHS
the unfettered discretion to create new categories of law-
fully present aliens. And, there is no basis for concluding
that Congress implicitly delegated to DHS the power to re-
classify categories of aliens as lawfully present. The immi-
gration statutes provide numerous ways to obtain lawful
presence, both temporary and permanent. The highly de-
tailed nature of these provisions indicates that Congress
has exhaustively provided for all of the ways that it thought
lawful presence should be obtainable, leaving no discretion
to DHS to add new pathways.
  For example, federal immigration laws provide over 60
temporary nonimmigrant visa options, including visas for
ambassadors, full-time students and their spouses and chil-
dren, those engaged to marry a United States citizen within

status when the Attorney General finds that removal to a
country with an ongoing armed conflict “would pose a seri-

and allow the Secretary of Homeland Security (in consulta-
tion with the Secretary of State) to waive visa requirements
for certain aliens for up to 90 days, §§1187(a)–(d).
   The immigration laws are equally complex and detailed
when it comes to obtaining lawful permanent residence.
Congress has expressly specified numerous avenues for
obtaining an immigrant visa, which aliens may then use
to become lawful permanent residents. §§1201, 1255(a).
Among other categories, immigrant visas are available to
specified family-sponsored aliens, aliens with advanced de-
grees or exceptional abilities, certain types of skilled and
unskilled workers, “special immigrants,” and those enter-
ing the country to “engag[e] in a new commercial enter-
prise.” §§1153(a)–(b), 1154; see also Congressional Re-
search Service, Nonimmigrant and Immigrant Visa
Categories, at 6–7 (Table 2). Refugees and asylees also may
receive lawful permanent residence under certain condi-
tions, §1159; 8 CFR §§209.1, 209.2.4 As with temporary
lawful presence, each avenue to lawful permanent resi-
dence status has its own set of rules and exceptions.5

procuring an alien’s admission as an immigrant”); §1186b (qualifying
business entrepreneurs).
  5 For instance, Congress has carved out rules for aliens who served in

the Armed Forces, §§1438–1440, and alien spouses who have been sub-
ject to domestic abuse, §§1186a(c)(4)(C)–(D).

carefully provid[e] legal designations allowing defined clas-
ses of aliens to be lawfully present.” Texas, 809 F. 3d, at
179. In light of this elaborate statutory scheme, the lack of
any similar provision for DACA recipients convincingly es-
tablishes that Congress left DHS with no discretion to cre-
ate an additional class of aliens eligible for lawful presence.
Congress knows well how to provide broad discretion, and
it has provided open-ended delegations of authority in stat-
utes too numerous to name. But when it comes to lawful
presence, Congress did something strikingly different. In-
stead of enacting a statute with “broad general directives”
and leaving it to the agency to fill in the lion’s share of the
details, Mistretta v. United States, 488 U. S. 361, 372
(1989), Congress put in place intricate specifications gov-
erning eligibility for lawful presence. This comprehensive
scheme indicates that DHS has no discretion to supplement
or amend the statutory provisions in any manner, least of
all by memorandum. See FDA v. Brown & Williamson To-
bacco Corp., 529 U. S. 120, 125 (2000) (An agency “may not
exercise its authority in a manner that is inconsistent with
the administrative structure that Congress enacted” (inter-
nal quotation marks omitted)); see also ETSI Pipeline Pro-
ject v. Missouri, 484 U. S. 495, 509–510 (1988).
                               2
  The relief that Congress has extended to removable al-
iens likewise confirms that DACA exceeds DHS’ delegated
authority. Through deferred action, DACA grants tempo-
rary relief to removable aliens on a programmatic scale.
See Texas, 328 F. Supp. 3d, at 714. But as with lawful pres-
ence, Congress did not expressly grant DHS the authority
to create categorical exceptions to the statute’s removal re-
quirements. And again, as with lawful presence, the intri-
cate level of detail in the federal immigration laws regard-
ing relief from removal indicates that DHS has no
discretionary authority to supplement that relief with an

entirely new programmatic exemption.
   At the outset, Congress clearly knows how to provide for
classwide deferred action when it wishes to do so. On mul-
tiple occasions, Congress has used express language to
make certain classes of individuals eligible for deferred ac-
tion. See 8 U. S. C. §§1154(a)(1)(D)(i)(II), (IV) (certain indi-
viduals covered under the Violence Against Women Act are
“eligible for deferred action”); Victims of Trafficking and Vi-
olence Protection Act of 2000, 114 Stat. 1522 (“ ‘Any individ-
ual described in subclause (I) is eligible for deferred ac-
tion’ ”); Uniting and Strengthening America by Providing
Appropriate Tools Required to Intercept and Obstruct Ter-
rorism (USA PATRIOT ACT) Act of 2001, §423(b), 115 Stat.
361 (“Such spouse, child, son, or daughter may be eligible
for deferred action”); National Defense Authorization Act
for Fiscal Year 2004, §§1703(c)(1)(A), (2), 117 Stat. 1694–
1695 (“Such spouse or child shall be eligible for deferred ac-
tion”).6 Congress has failed to provide similar explicit pro-
visions for DACA recipients, and the immigration laws con-
tain no indication that DHS can, at will, create its own
categorical policies for deferred action.
   Other provisions pertaining to relief from removal fur-
ther demonstrate that DHS lacked the delegated authority

——————
  6 In the DAPA litigation, DHS noted that some deferred-action pro-

grams have been implemented by the Executive Branch without explicit
legislation. But “ ‘past practice does not, by itself, create [executive]
power.’ ” Medellín v. Texas, 552 U. S. 491, 532 (2008) (quoting Dames &
Moore v. Regan, 453 U. S. 654, 686 (1981)). If any of these programs had
been challenged, it would seem that they would be legally infirm for the
same reasons as DACA. Moreover, if DHS had the authority to create
new categories of aliens eligible for deferred action, then all of Congress’
deferred-action legislation was but a superfluous exercise. Duncan v.
Walker, 533 U. S. 167, 174 (2001). Finally, whereas some deferred-action
programs were followed by legislation, DACA has existed for eight years,
and Congress is no closer to a legislative solution than it was in 2012.

to create DACA. As with lawful presence, Congress has
provided a plethora of methods by which aliens may seek
relief from removal. For instance, both permanent and
temporary residents can seek cancellation of removal if
they meet certain residency requirements and have not
committed certain crimes. §§1229b(a)–(b). And certain
nonpermanent residents may have their status adjusted to
permanent       residence    during     these    proceedings.
§1229b(b)(2). Aliens can apply for asylum or withholding of
removal during removal proceedings unless they have com-
mitted certain crimes. §§1158, 1231(b)(3). Applicants for
certain nonimmigrant visas may be granted a stay of re-
moval until the visa application is adjudicated. §1227(d).
And, aliens may voluntarily depart rather than be subject
to an order of removal. §1229c.
  In sum, like lawful presence, Congress has provided for
relief from removal in specific and complex ways. This nu-
anced detail indicates that Congress has provided the full
panoply of methods it thinks should be available for an al-
ien to seek relief from removal, leaving no discretion to DHS
to provide additional programmatic forms of relief.7
                              3
  Finally, DHS could not appeal to general grants of au-
thority, such as the Secretary’s ability to “perform such
other acts as he deems necessary for carrying out his au-
thority under the provisions of this chapter,” §1103(a)(3), or
to “[e]stablis[h] national immigration enforcement policies
and priorities,” 6 U. S. C. §202(5). See also 8 U. S. C.

   7 It is uncontested that deferred action frequently occurs on a case-by-

case basis, often justified on the grounds that the agency lacks resources
to remove all removable aliens. Even assuming that these ad hoc exer-

agency confronting resource constraints may change its own conduct, but
it cannot change the law.” Utility Air Regulatory Group v. EPA, 573 U. S.

symmetrical and coherent regulatory scheme,” Gustafson v.
Alloyd Co., 513 U. S. 561, 569 (1995), these grants of au-
thority must be read alongside the express limits contained
within the statute. Basing the Secretary’s ability to com-
pletely overhaul immigration law on these general grants
of authority would eviscerate that deliberate statutory
scheme by “allow[ing the Secretary of DHS] to grant lawful
presence . . . to any illegal alien in the United States.”
Texas, 809 F. 3d, at 184. Not only is this “an untenable po-
sition in light of the INA’s intricate system,” ibid., but it
would also render many of those provisions wholly super-
fluous due to DHS’ authority to disregard them at will,
Duncan v. Walker, 533 U. S. 167, 174 (2001). And in addi-
tion to these fatal problems, adopting a broad interpreta-
tion of these general grants of authority would run afoul of
the presumption that “Congress . . . does not alter the fun-
damental details of a regulatory scheme in vague terms or
ancillary provisions.” Whitman v. American Trucking
Assns., Inc., 531 U. S. 457, 468 (2001). And it would also
conflict with the major questions doctrine, which is based
on the expectation that Congress speaks clearly when it del-
egates the power to make “decisions of vast economic and
political significance.” Utility Air Regulatory Group v. EPA,
573 U. S. 302, 324 (2014) (UARG) (internal quotation
marks omitted); see also Texas, 787 F. 3d, at 760–761.
   Read together, the detailed statutory provisions govern-
ing temporary and lawful permanent resident status, relief
from removal, and classwide deferred-action programs lead
ineluctably to the conclusion that DACA is “inconsisten[t]
with the design and structure of the statute as a whole.”
University of Tex. Southwestern Medical Center v. Nassar,
570 U. S. 338, 353 (2013). As the District Court stated in

individuals Congress has deemed deportable or removable.”
Texas v. United States, 86 F. Supp. 3d 591, 654 (SD Tex.
2015). The immigration statutes contain a level of granular
specificity that is exceedingly rare in the modern adminis-
trative state. It defies all logic and common sense to con-
clude that a statutory scheme detailed enough to provide
conditional lawful presence to groups as narrowly defined
as “alien entrepreneurs,” §1186b, is simultaneously capa-
cious enough for DHS to grant lawful presence to almost
two million illegal aliens with the stroke of a Cabinet secre-
tary’s pen.
                                B
   Then-Attorney General Sessions concluded that the ini-
tial DACA program suffered from the “same legal . . . de-
fects” as DAPA and expanded DACA, finding that, like
those programs, DACA was implemented without statutory
authority. App. 877–878. Not only was this determination
correct, but it is also dispositive for purposes of our review.
“It is axiomatic that an administrative agency’s power . . .
is limited to the authority granted by Congress.” Bowen v.
Georgetown Univ. Hospital, 488 U. S. 204, 208 (1988). DHS
had no authority here to create DACA, and the unlawful-
ness of that program is a sufficient justification for its re-
scission.
   The majority opts for a different path, all but ignoring
DACA’s substantive legal defect. See ante, at 18–19. On
the majority’s understanding of APA review, DHS was re-
quired to provide additional policy justifications in order to
rescind an action that it had no authority to take. This rule
“has no basis in our jurisprudence, and support for [it] is
conspicuously absent from the Court’s opinion.” Massachu-
setts v. EPA, 549 U. S. 497, 536 (2007) (ROBERTS, C. J., dis-
senting).

surprising in light of our Constitution’s separation of pow-
ers. No court can compel Executive Branch officials to ex-
ceed their congressionally delegated powers by continuing
a program that was void ab initio. Cf. Clinton v. City of New
York, 524 U. S. 417 (1998); INS v. Chadha, 462 U. S. 919
(1983); see also EPA v. EME Homer City Generation, L. P.,
572 U. S. 489, 542, n. 5 (2014) (Scalia, J., dissenting); Public
Citizen v. Department of Justice, 491 U. S. 440, 487 (1989)
(Kennedy, J., concurring in judgment). In reviewing agency
action, our role is to ensure that Executive Branch officials
do not transgress the proper bounds of their authority, Ar-
lington, 569 U. S., at 327 (ROBERTS, C. J., dissenting), not
to perpetuate a decision to unlawfully wield power in direct
contravention of the enabling statute’s clear limits, see
UARG, 573 U. S., at 327–328; Barnhart v. Sigmon Coal Co.,
534 U. S. 438, 462 (2002).
   Under our precedents, DHS can only exercise the author-
ity that Congress has chosen to delegate to it. See UARG,
573 U. S., at 327. In implementing DACA, DHS under the
Obama administration arrogated to itself power it was not
given by Congress. Thus, every action taken by DHS under
DACA is the unlawful exercise of power. Now, under the
Trump administration, DHS has provided the most compel-
ling reason to rescind DACA: The program was unlawful
and would force DHS to continue acting unlawfully if it car-
ried the program forward.
                              III
   The majority’s demanding review of DHS’ decisionmak-
ing process is especially perverse given that the 2012 mem-
orandum flouted the APA’s procedural requirements—the
very requirements designed to prevent arbitrary deci-
sionmaking. Even if DHS were authorized to create DACA,
it could not do so without undertaking an administrative
rulemaking. The fact that DHS did not engage in this pro-
cess likely provides an independent basis for rescinding

DACA. But at the very least, this procedural defect com-
pounds the absurdity of the majority’s position in these
cases.
   As described above, DACA fundamentally altered the im-
migration laws. It created a new category of aliens who, as
a class, became exempt from statutory removal procedures,
and it gave those aliens temporary lawful presence. Both
changes contravened statutory limits. DACA is thus what
is commonly called a substantive or legislative rule.8 As the
name implies, our precedents state that legislative rules
are those that “have the force and effect of law.” Chrysler
Corp. v. Brown, 441 U. S. 281, 295 (1979) (internal quota-
tion marks omitted).
   Our precedents allow the vast majority of legislative
rules to proceed through so-called “informal” notice and
comment rulemaking. See United States v. Florida East
Coast R. Co., 410 U. S. 224, 237–238 (1973).9 But under our
precedents, an agency must engage in certain procedures
mandated by the APA before its rule carries legal force. Ki-

nothing more than a policy of prosecutorial discretion, which would make
its rescission unreviewable. See Heckler v. Chaney, 470 U. S. 821, 831
(1985).

much more formal process for most rulemaking.” Perez v. Mortgage

U. S. C. §§553(b)–(c); see also Kisor, 588 U. S., at ___ (opin-
ion of GORSUCH, J.) (slip op., at 17). As we have recognized
recently, use of the word “shall” indicates that these proce-
dures impose mandatory obligations on the agency before it
can adopt a valid binding regulation. See Maine Commu-
nity Health Options v. United States, 590 U. S. ___, ___
(2020) (slip op., at 12). After undergoing notice and com-
ment, the agency then publishes the final rule, which must
“articulate a satisfactory explanation for [the] action in-
cluding a rational connection between the facts found and
the choice made.” Motor Vehicle Mfrs. Assn. of United
States, Inc. v. State Farm Mut. Automobile Ins. Co., 463
U. S. 29, 43 (1983) (internal quotation marks omitted).
Only after completing this process is the legislative rule a
valid law. See Kisor, 588 U. S., at ___ (opinion of GORSUCH,
J.) (slip op., at 17).10
   Because DACA has the force and effect of law, DHS was
required to observe the procedures set out in the APA if it
wanted to promulgate a legislative rule. It is undisputed,
however, that DHS did not do so. It provided no oppor-
tunity for interested parties to submit comments regarding
the effect that the program’s dramatic and very significant
change in immigration law would have on various aspects
of society. It provided no discussion of economic considera-
tions or national security interests. Nor did it provide any
substantial policy justifications for treating young people

——————
  10 The APA also provides certain exceptions from notice and comment

rulemaking. For example, an agency may promulgate a legally binding
rule without notice and comment if good cause exists to do so. 5 U. S. C.
§553(b)(B). This text would become a nullity if the agency could achieve
the same effect by simply dispensing with notice and comment proce-
dures altogether.

brought to this country differently from other classes of al-
iens who have lived in the country without incident for
many years. And, it did not invoke any law authorizing
DHS to create such a program beyond its inexplicable as-
sertion that DACA was consistent with existing law. Be-
cause DHS failed to engage in the statutorily mandated
process, DACA never gained status as a legally binding reg-
ulation that could impose duties or obligations on third par-
ties. See id., at ___ (plurality opinion) (slip op., at 23); id.,
at ___ (opinion of GORSUCH, J.) (slip op., at 17).
   Given this state of affairs, it is unclear to me why DHS
needed to provide any explanation whatsoever when it de-
cided to rescind DACA. Nothing in the APA suggests that
DHS was required to spill any ink justifying the rescission
of an invalid legislative rule, let alone that it was required
to provide policy justifications beyond acknowledging that
the program was simply unlawful from the beginning. And,
it is well established that we do not remand for an agency
to correct its reasoning when it was required by law to take
or abstain from an action. See Morgan Stanley Capital
Group Inc. v. Public Util. Dist. No. 1 of Snohomish Cty., 554
U. S. 527, 544–545 (2008). Here, remand would be futile,
because no amount of policy explanation could cure the fact
that DHS lacked statutory authority to enact DACA in the
first place.
   Instead of recognizing this, the majority now requires the
rescinding Department to treat the invalid rule as though
it were legitimate. As just explained, such a requirement
is not supported by the APA.11 It is also absurd, as evi-
denced by its application to DACA in these cases. The ma-
jority insists that DHS was obligated to discuss its choices
regarding benefits and forbearance in great detail, even

  11 Thus, it is not that the APA “should not” be construed to support the

majority’s result, ante, at 26 (emphasis added), it is that the APA does
not and cannot support that result.

though no such detailed discussion accompanied DACA’s is-
suance. And, the majority also requires DHS to discuss re-
liance interests at length, even though deferred action tra-
ditionally does not take reliance interests into account and
DHS was not forced to explain its treatment of reliance in-
terests in the first instance by going through notice and
comment. See infra, at 23–24. The majority’s demand for
such an explanation here simply makes little sense.
   At bottom, of course, none of this matters, because DHS
did provide a sufficient explanation for its action. DHS’
statement that DACA was ultra vires was more than suffi-
cient to justify its rescission.12 By requiring more, the ma-
jority has distorted the APA review process beyond recogni-
tion, further burdening all future attempts to rescind
unlawful programs. Plaintiffs frequently bring successful
challenges to agency actions by arguing that the agency has
impermissibly dressed up a legislative rule as a policy state-
ment and must comply with the relevant procedures before
functionally binding regulated parties. See, e.g., Mendoza
v. Perez, 754 F. 3d 1002 (CADC 2014); Natural Resources

tional Family Planning & Reproductive Health Assn., Inc.

when a rescinding agency inherits an invalid legislative
rule that ignored virtually every rulemaking requirement
of the APA, it will be obliged to overlook that reality. In-
stead of simply terminating the program because it did not
go through the requisite process, the agency will be com-
pelled to treat an invalid legislative rule as though it were
legitimate.13

  12 I express no view on what other reasons would justify an agency’s

decision to rescind a procedurally unlawful action. I merely point out
that correctly concluding that the program was illegal is sufficient.
  13 In my view, even if DACA were permitted under the federal immi-

gration laws and had complied with the APA, it would still violate the
Constitution as an impermissible delegation of legislative power. See

  Even if I were to accept the majority’s premise that
DACA’s rescission required additional policy justifications,
the majority’s reasons for setting aside the agency’s deci-
sion still fail.
                               A
  First, the majority claims that the Fifth Circuit discussed
only the legality of the 2014 memorandum’s conferral of
benefits, not its “forbearance component”—i.e., the decision
not to place DACA recipients into removal proceedings.
Ante, at 20. The majority, therefore, claims that, notwith-
standing the then-Attorney General’s legal conclusion,
then-Acting Secretary Duke was required to consider re-
voking DACA recipients’ lawful presence and other at-
tendant benefits while continuing to defer their removal.
Ante, at 22–23. Even assuming the majority correctly char-
acterizes the Fifth Circuit’s opinion, it cites no authority for
the proposition that arbitrary and capricious review re-
quires an agency to dissect an unlawful program piece by
piece, scrutinizing each separate element to determine
whether it would independently violate the law, rather
than just to rescind the entire program.14
——————
Department of Transportation v. Association of American Railroads, 575
U. S. 43, 77 (2015) (THOMAS, J., concurring in judgment). Putting aside
this constitutional concern, however, the notice and comment process at
least attempts to provide a “surrogate political process” that takes some
of the sting out of the inherently undemocratic and unaccountable rule-
making process. Asimow, Interim-Final Rules: Making Haste Slowly, 51
Admin. L. Rev. 703, 708 (1999).
   14 The majority’s interpretation of the Fifth Circuit’s opinion is highly

questionable. Because a grant of deferred action renders DACA recipi-
ents eligible for certain benefits and work authorization, it is far from
clear that the Department could separate DACA’s “forbearance compo-
nent” from the major benefits it conferred without running into yet an-
other APA problem. The majority points to the fact that, under the Pa-
tient Protection and Affordable Care Act of 2010, relevant regulations
exclude those receiving deferred action through DACA from coverage.

                                  of THOMAS , J. and dissenting in part

   The then-Attorney General reviewed the thorough deci-
sions of the District Court and the Fifth Circuit. Those
courts exhaustively examined the INA’s text and structure,
the relevant provisions of other federal immigration stat-
utes, the historical practice of deferred action, and the gen-
eral grants of statutory authority to set immigration policy.
Both decisions concluded that DAPA and expanded DACA
violated the carefully crafted federal immigration scheme,
that such violations could not be justified through reference
to past exercises of deferred action, and that the general
grants of statutory authority did not give DHS the power to
enact such a sweeping nonenforcement program. Based on
the reasoning of those decisions, then-Attorney General
Sessions concluded that DACA was likewise implemented
without statutory authority. He directed DHS to restore
the rule of law. DHS followed the then-Attorney General’s
legal analysis and rescinded the program. This legal con-
clusion more than suffices to supply the “reasoned analysis”
necessary to rescind an unlawful program. State Farm, 463
U. S., at 42.
   The majority has no answer except to suggest that this
approach is inconsistent with State Farm. See ante, at 21–
22. But in doing so, the majority ignores the fact that, un-
like the typical “prior policy” contemplated by the Court in
——————
Ante, at 19, n. 5. But that misses the point. Those regulations were
promulgated before “anyone with deferred action under the DACA pro-
cess applie[d]” for those benefits. See 77 Fed. Reg. 52616 (2012). By
contrast, DACA recipients have been eligible for and have received Med-
icare, Social Security, and work authorization for years. DHS therefore
is not writing on a blank slate. Under the majority’s rule, DHS would
need to amend all relevant regulations and explain why all recipients of
deferred action who have previously received such benefits may no longer
receive them. Alternatively and perhaps more problematically, it would
need to provide a reason why other recipients of deferred action should
continue to qualify, while DACA recipients should not. It thus seems
highly likely that the majority’s proposed course of action would be sub-
ject to serious arbitrary and capricious challenges.

State Farm, DACA is unlawful. Neither State Farm nor
any other decision cited by the majority addresses what an
agency must do when it has inherited an unlawful program.
It is perhaps for this reason that, rather than responding
with authority of its own, the majority simply opts to excise
the “unlawful policy” aspect from its discussion.
                              B
   Second, the majority claims that DHS erred by failing to
take into account the reliance interests of DACA recipients.
Ante, at 23–26. But reliance interests are irrelevant when
assessing whether to rescind an action that the agency
lacked statutory authority to take. No amount of reliance
could ever justify continuing a program that allows DHS to
wield power that neither Congress nor the Constitution
gave it. Any such decision would be “not in accordance with
law” or “in excess of statutory . . . authority.” 5 U. S. C.
§§706(2)(A), (C). Accordingly, DHS would simply be engag-
ing in yet another exercise of unlawful power if it used reli-
ance interests to justify continuing the initially unlawful
program, and a court would be obligated to set aside that
action.15
   Even if reliance interests were sometimes relevant when
rescinding an ultra vires action, the rescission still would
not be arbitrary and capricious here. Rather, as the major-
ity does not dispute, the rescission is consistent with how
deferred action has always worked. As a general matter,
deferred action creates no rights—it exists at the Govern-
ment’s discretion and can be revoked at any time. See App.


——————
  15 The majority contends that this argument does not carry force be-

cause the rescission implemented a winddown period during which re-
cipients would continue to receive benefits. But whether DHS’ decision
to wind down DACA was lawful is a separate question from whether
DHS was required to consider reliance interests before discontinuing an
unlawful program.

(U visas); 62 Fed. Reg. 63249, 63253 (1997) (discussing
Exec. Order No. 12711 for certain citizens of the People’s
Republic of China). The Government has made clear time
and again that, because “deferred action is not an immigra-
tion status, no alien has the right to deferred action. It is
used solely in the discretion of the [Government] and con-
fers no protection or benefit upon an alien.” DHS Immigra-

tor of Operations, DHS, Citizenship and Immigration
Servs., to Director, Vt. Serv. Center, p. 5 (2003). Thus, con-
trary to the majority’s unsupported assertion, ante, at 23,
this longstanding administrative treatment of deferred ac-
tion provides strong evidence and authority for the proposi-
tion that an agency need not consider reliance interests in
this context.16
   Finally, it is inconceivable to require DHS to study reli-
ance interests before rescinding DACA considering how the
program was previously defended. DHS has made clear
since DACA’s inception that it would not consider such re-
liance interests. Contemporaneous with the DACA memo,
DHS stated that “DHS can terminate or renew deferred ac-
tion at any time at the agency’s discretion.” Consideration

   16 The majority’s approach will make it far more difficult to change

deferred-action programs going forward, which is hardly in keeping with
this Court’s own understanding that deferred action is an “exercise in
administrative discretion” used for administrative “convenience.” Reno
v. American-Arab Anti-Discrimination Comm., 525 U. S. 471, 484 (1999).
Agencies will likely be less willing to grant deferred action knowing that
any attempts to undo it will require years of litigation and time-consuming
rulemakings.

because deferred action created no rights on which recipi-

removal proceedings at any time at its discretion.” Brief for
Appellants in Texas v. United States, No. 15–40238, p. 7;
see also id., at 45–46. And before this Court, in that same

tion to revoke deferred action unilaterally, without notice
or process.” Brief for United States in United States v.
Texas, O. T. 2015, No. 15–674, p. 5; see also id., at 37. If
that treatment of reliance interests was incorrect, it pro-
vides yet one more example of a deficiency in DACA’s issu-
ance, not its rescission.

now plays in our constitutional system should consider
what has happened in these cases. Early in the term of the
current President, his administration took the controver-
sial step of attempting to rescind the Deferred Action for
Childhood Arrivals (DACA) program. Shortly thereafter,
one of the nearly 700 federal district court judges blocked
this rescission, and since then, this issue has been mired in
litigation. In November 2018, the Solicitor General filed
petitions for certiorari, and today, the Court still does not
resolve the question of DACA’s rescission. Instead, it tells
the Department of Homeland Security to go back and try
again. What this means is that the Federal Judiciary, with-
out holding that DACA cannot be rescinded, has prevented
that from occurring during an entire Presidential term.
Our constitutional system is not supposed to work that way.
   I join JUSTICE THOMAS’s opinion. DACA presents a deli-
cate political issue, but that is not our business. As JUSTICE
THOMAS explains, DACA was unlawful from the start, and
that alone is sufficient to justify its termination. But even
if DACA were lawful, we would still have no basis for over-
turning its rescission. First, to the extent DACA repre-
sented a lawful exercise of prosecutorial discretion, its re-
scission represented an exercise of that same discretion,
and it would therefore be unreviewable under the Adminis-
trative Procedure Act. 5 U. S. C. §701(a)(2); see Heckler v.
Chaney, 470 U. S. 821, 831–832 (1985). Second, to the ex-
tent we could review the rescission, it was not arbitrary and
capricious for essentially the reasons explained by JUSTICE
KAVANAUGH. See post, at 4–6 (opinion concurring in the
judgment in part and dissenting in part).

2        DEPARTMENT OF HOMELAND SECURITY v.
               REGENTS OF UNIV. OF CAL.
                 Opinion of KAVANAUGH, J.

  For the last 20 years, the country has engaged in conse-
quential policy, religious, and moral debates about the legal
status of millions of young immigrants who, as children,
were brought to the United States and have lived here ever
since. Those young immigrants do not have legal status in
the United States under current statutory law. They live,
go to school, and work here with uncertainty about their
futures. Despite many attempts over the last two decades,
Congress has not yet enacted legislation to afford legal sta-
tus to those immigrants.
  In 2012, exercising its view of the Executive’s prosecuto-
rial discretion under Article II and the immigration laws,
President Obama’s administration unilaterally instituted a
program known as Deferred Action for Childhood Arrivals,
or DACA. Under DACA, eligible young immigrants may
apply for and receive deferred action. They must renew
their DACA status every two years. Under the program,
the Executive Branch broadly forbears from enforcing cer-
tain immigration removal laws against DACA recipients.
And by virtue of the forbearance, DACA recipients also be-
come eligible for work authorization and other benefits.
  Since 2017, President Trump’s administration has
sought to rescind DACA based on its different and narrower
understanding of the Executive’s prosecutorial discretion
under Article II and the immigration laws. In its view, the
Executive Branch legally may not, and as a policy matter
should not, unilaterally forbear from enforcing the immi-
gration laws against such a large class of individuals. The
current administration has stated that it instead wants to
work with Congress to enact comprehensive legislation that
would address the legal status of those immigrants together
with other significant immigration issues.
  The question before the Court is whether the Executive
Branch acted lawfully in ordering rescission of the ongoing
DACA program. To begin with, all nine Members of the
Court accept, as do the DACA plaintiffs themselves, that
                 Cite as: 591 U. S. ____ (2020)           3

                   Opinion of KAVANAUGH, J.

the Executive Branch possesses the legal authority to re-
scind DACA and to resume pre-DACA enforcement of the
immigration laws enacted by Congress. Having previously
adopted a policy of prosecutorial discretion and nonenforce-
ment with respect to a particular class of offenses or indi-
viduals, the Executive Branch has the legal authority to re-
scind such a policy and resume enforcing the law enacted
by Congress. The Executive Branch’s exercise of that re-
scission authority is subject to constitutional constraints
and may also be subject to statutory constraints. The nar-
row legal dispute here concerns a statutory constraint—
namely, whether the Executive Branch’s action to rescind
DACA satisfied the general arbitrary-and-capricious stand-
ard of the Administrative Procedure Act, or APA.
  The APA’s arbitrary-and-capricious standard requires
that agency action be reasonable and reasonably explained.
As the Court has long stated, judicial review under that
standard is deferential to the agency. The Court may not
substitute its policy judgment for that of the agency. The
Court simply ensures that the agency has acted within a
broad zone of reasonableness and, in particular, has reason-
ably considered the relevant issues and reasonably ex-
plained the decision. See FCC v. Fox Television Stations,
Inc., 556 U. S. 502 (2009); Motor Vehicle Mfrs. Assn. of
United States, Inc. v. State Farm Mut. Automobile Ins. Co.,
463 U. S. 29 (1983).
  The Executive Branch explained its decision to rescind
DACA in two sequential memorandums by successive Sec-
retaries of Homeland Security: the 2017 Duke Memoran-
dum and the 2018 Nielsen Memorandum. The Duke Mem-
orandum focused on DACA’s perceived legal flaws. The
Court today finds the Duke Memorandum insufficient un-
der the APA’s arbitrary-and-capricious standard.
  But regardless of whether the Court is correct about the
Duke Memorandum, the Nielsen Memorandum more fully
explained the Department’s legal reasons for rescinding
4         DEPARTMENT OF HOMELAND SECURITY v.
                REGENTS OF UNIV. OF CAL.
                  Opinion of KAVANAUGH, J.

DACA, and clarified that even if DACA were lawful, the De-
partment would still rescind DACA for a variety of policy
reasons. The Nielsen Memorandum also expressly ad-
dressed the reliance interests of DACA recipients. The
question under the APA’s deferential arbitrary-and-capri-
cious standard is not whether we agree with the Depart-
ment’s decision to rescind DACA. The question is whether
the Nielsen Memorandum reasonably explained the deci-
sion to rescind DACA. Under ordinary application of the
arbitrary-and-capricious standard, the Nielsen Memoran-
dum—with its alternative and independent rationales and
its discussion of reliance—would pass muster as an expla-
nation for the Executive Branch’s action.
   The Nielsen Memorandum was issued nine months after
the Duke Memorandum. Under the Administrative Proce-
dure Act, the Nielsen Memorandum is itself a “rule” setting
forth “an agency statement of general . . . applicability and
future effect designed to implement . . . policy.” 5 U. S. C.
§551(4). Because it is a rule, the Nielsen Memorandum con-
stitutes “agency action.” §551(13). As the Secretary of
Homeland Security, Secretary Nielsen had the authority to
decide whether to stick with Secretary Duke’s decision to
rescind DACA, or to make a different decision. Like Secre-
tary Duke, Secretary Nielsen chose to rescind DACA, and
she provided additional explanation. Her memorandum
was akin to common forms of agency action that follow ear-
lier agency action on the same subject—for example, a sup-
plemental or new agency statement of policy, or an agency
order with respect to a motion for rehearing or reconsider-
ation. Courts often consider an agency’s additional expla-
nations of policy or additional explanations made, for exam-
ple, on agency rehearing or reconsideration, or on remand
from a court, even if the agency’s bottom-line decision itself
does not change.
   Yet the Court today jettisons the Nielsen Memorandum
by classifying it as a post hoc justification for rescinding
                 Cite as: 591 U. S. ____ (2020)            5

                   Opinion of KAVANAUGH, J.

DACA. Ante, at 14–16. Under our precedents, however, the
post hoc justification doctrine merely requires that courts
assess agency action based on the official explanations of
the agency decisionmakers, and not based on after-the-fact
explanations advanced by agency lawyers during litigation
(or by judges). See, e.g., State Farm, 463 U. S., at 50
(“courts may not accept appellate counsel’s post hoc ration-
alizations for agency action”); FPC v. Texaco Inc., 417 U. S.
380, 397 (1974) (same); NLRB v. Metropolitan Life Ins. Co.,
380 U. S. 438, 443–444 (1965) (same); Burlington Truck
Lines, Inc. v. United States, 371 U. S. 156, 168–169 (1962)
(same). As the D. C. Circuit has explained, the post hoc jus-
tification doctrine “is not a time barrier which freezes an
agency’s exercise of its judgment after an initial decision
has been made and bars it from further articulation of its
reasoning. It is a rule directed at reviewing courts which
forbids judges to uphold agency action on the basis of ra-
tionales offered by anyone other than the proper deci-
sionmakers.” Alpharma, Inc. v. Leavitt, 460 F. 3d 1, 6
(2006) (Garland, J.) (internal quotation marks omitted).
   Indeed, the ordinary judicial remedy for an agency’s in-
sufficient explanation is to remand for further explanation
by the relevant agency personnel. It would make little
sense for a court to exclude official explanations by agency
personnel such as a Cabinet Secretary simply because the
explanations are purportedly post hoc, and then to turn
around and remand for further explanation by those same
agency personnel. Yet that is the upshot of the Court’s ap-
plication of the post hoc justification doctrine today. The
Court’s refusal to look at the Nielsen Memorandum seems
particularly mistaken, moreover, because the Nielsen
Memorandum shows that the Department, back in 2018,
considered the policy issues that the Court today says the
Department did not consider. Ante, at 20–26.
   To be sure, cases such as Overton Park and Camp v. Pitts
suggest that courts reviewing certain agency adjudications

may in some circumstances decline to examine an after-the-
fact agency explanation. See Camp v. Pitts, 411 U. S. 138,
142–143 (1973) (per curiam); Citizens to Preserve Overton
Park, Inc. v. Volpe, 401 U. S. 402, 419–421 (1971). But
agency adjudications are “concerned with the determina-
tion of past and present rights and liabilities,” Attorney
General’s Manual on the Administrative Procedure Act 14
(1947), and implicate the due process interests of the indi-
vidual parties to the adjudication. Judicial review of an ad-
judication therefore ordinarily focuses on what happened
during the agency’s adjudication process of deciding that in-
dividual case.
   Even if certain agency adjudications have a slightly more
stringent restriction on post hoc explanations, the APA is
“based upon a dichotomy between rule making and adjudi-
cation,” ibid., and this case involves an ongoing agency rule
that has future effect—the rescission of DACA. The Nielsen
Memorandum implements and explains the rescission of
DACA. I am aware of no case from this Court, and the
Court today cites none, that has employed the post hoc jus-
tification doctrine to exclude an agency’s official explana-
tion of an agency rule. For purposes of arbitrary-and-capri-
cious review, it does not matter whether the latest official
explanation was two years ago or three years ago. What
matters is whether the explanation was reasonable and fol-
lowed the requisite procedures. In my view, the Court
should consider the Nielsen Memorandum in deciding
whether the Department’s rescission of DACA satisfies the
APA’s arbitrary-and-capricious standard.
   Because the Court excludes the Nielsen Memorandum,
the Court sends the case back to the Department of Home-
land Security for further explanation. Although I disagree
with the Court’s decision to remand, the only practical con-
sequence of the Court’s decision to remand appears to be
some delay. The Court’s decision seems to allow the De-
partment on remand to relabel and reiterate the substance

tion as suggested in the Court’s opinion. Ante, at 23–26.*

  The Court’s resolution of this narrow APA issue of course
cannot eliminate the broader uncertainty over the status of
the DACA recipients. That uncertainty is a result of Con-
gress’s inability thus far to agree on legislation, which in
turn has forced successive administrations to improvise,
thereby triggering many rounds of relentless litigation with
the prospect of more litigation to come. In contrast to those
necessarily short-lived and stopgap administrative
measures, the Article I legislative process could produce a
sturdy and enduring solution to this issue, one way or the
other, and thereby remove the uncertainty that has per-
sisted for years for these young immigrants and the Na-

   * Because I conclude that the Executive Branch satisfied the APA’s ar-
bitrary-and-capricious standard, I need not consider whether its prose-
cutorial enforcement policy was “committed to agency discretion by law”
and therefore not subject to APA arbitrary-and-capricious review in the
first place. 5 U. S. C. §701(a)(2). Several judges have advanced argu-
ments suggesting that DACA—at least to the extent it was simply an
exercise of forbearance authority—and the repeal of DACA are decisions
about whether and to what extent to exercise prosecutorial discretion
against a class of offenses or individuals, and are therefore unreviewable
under the APA as “committed to agency discretion by law.” Ibid.; see

tion’s immigration system. In the meantime, as to the nar-
row APA question presented here, I appreciate the Court’s
careful analysis, but I ultimately disagree with its treat-
ment of the Nielsen Memorandum. I therefore respectfully
dissent from the Court’s judgment on plaintiffs’ APA claim,
and I concur in the judgment insofar as the Court rejects
plaintiffs’ equal protection claim.
