    SUMMARY*
    Immigration /Preliminary Injunctions
    The panel affirmed the district court’s grant of a
    preliminary injunction setting aside the Migrant Protection
    Protocols (“MPP”), under which non-Mexican asylum
    seekers who present themselves at the southern border of the
    United States are required to wait in Mexico while their
    asylum applications are adjudicated.
    After the MPP went into effect in January 2019,
    individual and organizational plaintiffs sought an injunction,
    arguing, inter alia, that the MPP is inconsistent with the
    Immigration and Nationality Act (“INA”), and that they have
    a right to a remedy under the Administrative Procedure Act
    (“APA”). The district court issued a preliminary injunction
    setting aside the MPP.
    The Government appealed and requested an emergency
    stay in this court pending appeal. In three written opinions,
    a motions panel unanimously granted the emergency stay. In
    a per curiam opinion, the motions panel disagreed, by a vote
    of two to one, with the district court’s holding that plaintiffs
    were likely to succeed in their statutory argument that the
    MPP is inconsistent with 
    8 U.S.C. § 1225
    (b). Judge Watford
    concurred in that opinion, but wrote separately to express
    concern that the MPP is arbitrary and capricious because it
    lacks sufficient non-refoulement protections. Judge Fletcher

    4              INNOVATION LAW LAB V. WOLF
    concurred only in the result, arguing that the MPP was
    inconsistent with 
    8 U.S.C. § 1225
    (b).
    The current panel first noted that the individual plaintiffs,
    all of whom have been returned to Mexico under the MPP,
    obviously have standing. The panel also concluded that the
    organizational plaintiffs have standing, noting their decreased
    ability to carry out their core missions as well as diversion of
    their resources.
    Addressing the question of whether a merits panel is
    bound by the analysis of a motions panel on a question of
    law, the panel followed East Bay Sanctuary Covenant v.
    Trump, Nos. 18-17274 and 18-17436 (9th Cir. Feb. 28, 2020),
    argued on the same day as this case, in which the court held
    that a motions panel’s legal analysis, performed during the
    course of deciding an emergency motion for a stay, is not
    binding on later merits panels. The panel also concluded that,
    even if a merits panel may be bound in some circumstances
    by a motions panel, this panel would not be bound: two of the
    three judges on the motions panel disagreed in part with the
    Government’s legal arguments in support of the MPP, and the
    panel’s per curiam opinion did not purport to decide
    definitively the legal questions presented. In this respect, the
    panel noted that Judge Fletcher specifically addressed the
    effect of the legal analysis of the motions panel and expressed
    the hope that the merits panel, with the benefit of full briefing
    and argument, would decide the legal questions differently.
    On the merits, the panel concluded that plaintiffs had
    shown a likelihood of success on their claim that the return-
    to-Mexico requirement of the MPP is inconsistent with
    § 1225(b). The Government argued that the MPP is
    authorized by § 1225(b)(2), which provides that, for certain
    INNOVATION LAW LAB V. WOLF                       5
    aliens arriving on land from a foreign territory contiguous to
    the United States, the Attorney General may return the aliens
    to that territory pending removal proceedings. Plaintiffs
    argued, however, that they were arriving aliens under
    § 1225(b)(1), rather than under § 1225(b)(2), and pointed out
    that there is a contiguous territory return provision in § (b)(2),
    but no such provision in § (b)(1).
    The panel agreed, explaining that there are two distinct
    categories of “applicants for admission” under § 1225. First,
    there are applicants described under § 1225(b)(1), who are
    inadmissible based on either of two grounds, both of which
    relate to their documents or lack thereof. Such applicants
    may be placed in either expedited removal proceedings or
    regular removal proceedings under § 1229a. Second, there
    are applicants described under § 1225(b)(2), who are, in the
    words of the statute, “other aliens,” “to whom paragraph
    [(b)](1)” does not apply; that is, § (b)(2) applicants are those
    who are inadmissible on grounds other than the two specified
    in § (b)(1). Such applicants are placed in regular removal
    proceedings. The panel noted that both § (b)(1) and § (b)(2)
    applicants can be placed in regular removal proceedings
    under § 1229a, though by different routes, but concluded that
    a § (b)(1) applicant does not become a § (b)(2) applicant, or
    vice versa, by virtue of being placed in a removal proceeding
    under § 1229a.
    Addressing the precise statutory question posed by the
    MPP, the panel held that a plain-meaning reading of
    § 1225(b)—as well as the Government’s longstanding and
    consistent practice—made clear that a § (b)(1) applicant may
    not be “returned” to a contiguous territory under
    § 1225(b)(2)(C), which is a procedure specific to a § (b)(2)
    applicant.
    6             INNOVATION LAW LAB V. WOLF
    The panel next concluded that plaintiffs had shown a
    likelihood of success on their claim that the MPP does not
    comply with the United States’ treaty-based non-refoulement
    obligations codified at 
    8 U.S.C. § 1231
    (b). The panel
    explained that refoulement occurs when a government returns
    aliens to a country where their lives or liberty will be
    threatened on account of race, religion, nationality,
    membership of a particular social group, or political opinion.
    Further, the United States is obliged by treaty—namely, the
    1951 United Nations Convention Relating to the Status of
    Refugees and the 1967 United Nations Protocol Relating to
    the Status of Refugees—and implementing statute—namely,
    § 1231(b)—to protect against refoulement of aliens arriving
    at the country’s borders.
    Plaintiffs argued that the MPP provides insufficient
    protection against refoulement. First, under the MPP, to stay
    in the United States during proceedings, an asylum seeker
    must show that it is “more likely than not” that he or she will
    be persecuted in Mexico, but that standard is higher than the
    ordinary standing in screening interviews, in which aliens
    need only establish a “credible fear,” which requires only a
    “significant possibility” of persecution. Second, an asylum
    seeker under the MPP is not entitled to advance notice of, and
    time to prepare for, the hearing with the asylum officer; to
    advance notice of the criteria the asylum officer will use; to
    the assistance of a lawyer during the hearing; or to any review
    of the asylum officer’s determination. Third, an asylum
    officer acting under the MPP does not ask an asylum seeker
    whether he or she fears returning to Mexico; instead, asylum
    seekers must volunteer, without any prompting, that they fear
    returning. The Government disagreed with plaintiffs on the
    grounds that: 1) § 1231(b) does not encompass a general non-
    INNOVATION LAW LAB V. WOLF                      7
    refoulement obligation; and 2) the MPP satisfies non-
    refoulement obligations by providing sufficient procedures.
    The panel rejected both arguments. With respect to the
    second argument, the panel noted that the Government
    pointed to no evidence supporting its speculations either that
    aliens will volunteer that they fear returning to Mexico, or
    that there is little danger to non-Mexican aliens in Mexico.
    The panel also noted that the Government provided no
    evidence to support its claim that any violence that returned
    aliens face in Mexico is unlikely to be violence on account of
    a protected ground. Further, the panel quoted numerous
    sworn declarations to the district court that directly
    contradicted the unsupported speculations of the Government.
    Addressing the other preliminary injunction factors, the
    panel concluded that there is a significant likelihood that the
    individual plaintiffs will suffer irreparable harm if the MPP
    is not enjoined; uncontested evidence in the record establishes
    that non-Mexicans returned to Mexico under the MPP risk
    substantial harm, even death, while they await adjudication of
    their applications for asylum. Further, the panel concluded
    that the balance of factors favored plaintiffs. While the
    Government has an interest in continuing to follow the
    directives of the MPP, the strength of that interest is
    diminished by the likelihood that the MPP is inconsistent
    with §§ 1225(b) and 1231(b). On the other side, the
    individual plaintiffs risk substantial harm, and the
    organizational plaintiffs are hindered in their ability to carry
    out their missions. The panel concluded that public interest
    similarly favored plaintiffs: while the public has a weighty
    interest in efficient administration of the immigration laws,
    the public also has an interest in ensuring that statutes enacted
    by their representatives are not imperiled by executive fiat.
    8             INNOVATION LAW LAB V. WOLF
    Finally, considering the scope of the district court’s
    injunction, the panel concluded that the district court did not
    abuse its discretion in setting aside the MPP. The panel
    recognized that nationwide injunctions have become
    increasingly controversial, but noted that it was a misnomer
    to call this order “nationwide,” as it operates only at the
    southern border and directs the action of officials only in four
    states. The panel explained that the district court did not
    abuse its discretion for two mutually reinforcing reasons.
    First, the APA provides that a reviewing court shall “set
    aside” action that is not in accordance with the law and that
    there is a presumption that an offending agency action should
    be set aside in its entirety. Second, cases implicating
    immigration policy have a particularly strong claim for
    uniform relief, and this court has consistently recognized the
    authority of district courts to enjoin unlawful policies on a
    universal basis. The panel also observed that the Fifth
    Circuit, one of only two other federal circuits with states
    along the southern border, has held that nationwide
    injunctions are appropriate in immigration cases.
    Dissenting, Judge Fernandez wrote that he believes that
    this panel is bound by the motions panel’s published decision
    in this case. Judge Fernandez wrote that the panel is bound
    by the law of the circuit, which binds all courts within a
    particular circuit, including the court of appeals itself, and
    remains binding unless overruled by the court sitting en banc,
    or by the Supreme Court. Further, Judge Fernandez wrote
    that, insofar as factual differences might allow precedent to
    be distinguished on a principled basis, in this case, the
    situation before this panel is in every material way the same
    as that before the motions panel. Judge Fernandez also stated
    that, in Lair v. Bullock, 
    798 F.3d 736
     (9th Cir. 2015), this
    court held that a motions panel’s published opinion binds
    INNOVATION LAW LAB V. WOLF                      9
    future panels the same as does a merits panel’s published
    opinion. Judge Fernandez also concluded that the law of the
    case doctrine binds this panel, noting that he did not perceive
    any of the exceptions to the doctrine to be involved here.
    Applying those doctrines, Judge Fernandez concluded
    that: 1) plaintiffs are not likely to succeed on their claim that
    the MPP was not authorized by § 1225(b)(2)(C); 2) plaintiffs
    are not likely to succeed on their claim that the MPP’s
    adoption violated the notice and comment provisions of the
    APA; and 3) the preliminary injunction should be vacated.
    Judge Fernandez stated that he expressed no opinion on
    whether the district court could issue a narrower injunction.

    OPINION
    W. FLETCHER, Circuit Judge:
    Plaintiffs brought suit in district court seeking an
    injunction against the Government’s recently promulgated
    Migrant Protection Protocols (“MPP”), under which non-
    Mexican asylum seekers who present themselves at our
    southern border are required to wait in Mexico while their
    asylum applications are adjudicated. The district court
    entered a preliminary injunction setting aside the MPP, and
    the Government appealed. We affirm.
    I. Background
    In January 2019, the Department of Homeland Security
    (“DHS”) promulgated the MPP without going through notice-
    and-comment rulemaking. The MPP provides that non-
    Mexican asylum seekers arriving at our southern border be
    “returned to Mexico for the duration of their immigration
    proceedings, rather than either being detained for expedited
    or regular removal proceedings or issued notices to appear for
    regular removal proceedings.” Innovation Law Lab v.
    Nielsen, 
    366 F. Supp. 3d 1110
    , 1114 (N.D. Cal. 2019)
    (quotation marks omitted). The MPP does not apply to
    certain groups, including “unaccompanied alien children,”
    “aliens processed for expedited removal,” “aliens with known
    physical [or] mental health issues,” “returning [Legal
    12            INNOVATION LAW LAB V. WOLF
    Permanent Residents] seeking admission,” and “aliens with
    an advance parole document or in parole status.”
    DHS issued guidance documents to implement the MPP.
    Under this guidance, asylum seekers who cross the border
    and are subject to the MPP are given a Notice to Appear in
    immigration court and returned to Mexico to await their court
    date. Asylum seekers may re-enter the United States to
    appear for their court dates. The guidance instructs officials
    not to return any alien who will more likely than not suffer
    persecution if returned to Mexico. However, this instruction
    applies only to an alien “who affirmatively states that he or
    she has a fear of persecution or torture in Mexico, or a fear of
    return to Mexico.” Officers are not instructed to ask aliens
    whether they fear returning to Mexico. If an asylum officer
    determines, based on an alien’s volunteered statement, that he
    or she will more likely than not suffer persecution in Mexico,
    the alien is not subject to return to Mexico under the MPP.
    The MPP went into effect on January 28, 2019. It was
    first implemented at the San Ysidro, California, port of entry
    and was later expanded across the entire southern border.
    The MPP has had serious adverse consequences for the
    individual plaintiffs. Plaintiffs presented evidence in the
    district court that they, as well as others returned to Mexico
    under the MPP, face targeted discrimination, physical
    violence, sexual assault, overwhelmed and corrupt law
    enforcement, lack of food and shelter, and practical obstacles
    to participation in court proceedings in the United States.
    The hardship and danger to individuals returned to Mexico
    under the MPP have been repeatedly confirmed by reliable
    news reports. See, e.g., Zolan Kanno-Youngs & Maya
    Averbuch, Waiting for Asylum in the United States, Migrants

    laredo-mexico-streets-danger-migrants-2019-10-08/.
    The organizational plaintiffs have also suffered serious
    adverse consequences. The MPP has substantially hindered
    the organizations’ “ability to carry out their core mission of
    providing representation to aliens seeking admission,
    including asylum seekers,” Innovation Law Lab, 366 F. Supp.
    3d at 1129, and has forced them to divert resources because
    of increased costs imposed by the MPP.
    The Government has not argued in this court that either
    the individual or organizational plaintiffs lack standing under
    Article III, but we have an independent obligation to
    determine our jurisdiction under Article III. The individual
    plaintiffs, all of whom have been returned to Mexico under
    the MPP, obviously have Article III standing. The
    organizational plaintiffs also have Article III standing. The
    Government conceded in the district court that the
    organizational plaintiffs have Article III standing based on
    14             INNOVATION LAW LAB V. WOLF
    East Bay Sanctuary Covenant v. Trump, 
    932 F.3d 742
    ,
    765–67 (9th Cir. 2018), given their decreased ability to carry
    out their core missions as well as the diversion of their
    resources, both caused by the MPP. See Innovation Law Lab,
    366 F. Supp. at 1120–22. Because East Bay Sanctuary
    Covenant was a decision by a motions panel on an emergency
    stay motion, we are not obligated to follow it as binding
    precedent. See discussion, infra, Part V.A. However, we are
    persuaded by its reasoning and hold that the organizational
    plaintiffs have Article III standing.
    II. Proceedings in the District Court
    Plaintiffs filed suit in district court seeking an injunction,
    alleging, inter alia, that the MPP is inconsistent with the
    Immigration and Nationality Act (“INA”), specifically
    
    8 U.S.C. §§ 1225
    (b) and 1231(b), and that they have a right
    to a remedy under 
    5 U.S.C. § 706
    (2)(A). Section 706(2)(A)
    provides, “The reviewing court shall . . . hold unlawful and
    set aside agency action, findings, and conclusions found to be
    . . . arbitrary, capricious, an abuse of discretion, or otherwise
    not in accordance with law.” (Internal numbering omitted.)
    The district court held that plaintiffs had shown a
    likelihood of success on the merits of their claim that the
    MPP is inconsistent with § 1225(b). Id. at 1123. The
    Government contended that the MPP is authorized by
    § 1225(b)(2). Plaintiffs argued, however, that they are
    arriving aliens under § 1225(b)(1) rather than under
    § 1225(b)(2). They pointed out that there is a contiguous
    territory return provision in § (b)(2) but no such provision in
    § (b)(1). The district court agreed with plaintiffs:
    INNOVATION LAW LAB V. WOLF                    15
    On its face, . . . the contiguous territory return
    provision may be applied to aliens described
    in subparagraph (b)(2)(A). Pursuant to
    subparagraph (b)(2)(B), however, that
    expressly excludes any alien “to whom
    paragraph [(b)](1) applies.”
    Id. (emphasis in original). The court concluded, “Applying
    the plain language of the statute, [the individual plaintiffs]
    simply are not subject to the contiguous territory return
    provision.” Id.
    The district court also held that plaintiffs had shown a
    likelihood of success on the merits of their claim that the
    MPP violates § 1231(b)(3), the statutory implementation of
    the United States’ treaty-based non-refoulement obligations.
    The district court held that “plaintiffs have shown they are
    more likely than not to prevail on the merits of their
    contention that defendants adopted the MPP without
    sufficient regard to refoulement issues.” Id. at 1127. In so
    holding, the district court noted that the MPP does not
    instruct asylum officers to ask asylum seekers whether they
    fear returning to Mexico. Rather, “the MPP provides only for
    review of potential refoulement concerns when an alien
    ‘affirmatively’ raises the point.” Id. The court further held
    that it was more likely than not that the MPP should have
    been adopted through notice-and-comment rulemaking with
    respect to the non-refoulement aspects of the MPP. Id.
    at 1128.
    With respect to the individual plaintiffs, the district court
    found that “[w]hile the precise degree of risk and specific
    harms that plaintiffs might suffer in this case may be
    debatable, there is no real question that it includes the
    16             INNOVATION LAW LAB V. WOLF
    possibility of irreparable injury, sufficient to support interim
    relief in light of the showing on the merits.” Id. at 1129.
    With respect to the organizational plaintiffs, the court found
    that they had “shown a likelihood of harm in terms of
    impairment of their ability to carry out their core mission of
    providing representation to aliens seeking admission,
    including asylum seekers.” Id. Finally, the court held that
    the balance of equities and the public interest support the
    issuance of a preliminary injunction. Id.
    Relying on a decision of our court, the district court
    issued a preliminary injunction setting aside the MPP. The
    court noted:
    [D]efendants have not shown the injunction in
    this case can be limited geographically. This
    is not a case implicating local concerns or
    values. There is no apparent reason that any
    of the places to which the MPP might
    ultimately be extended have interests that
    materially differ from those presented in San
    Ysidro.
    Id. at 1130.
    III. Proceedings Before the Motions Panel
    The district court issued its preliminary injunction on
    April 8, 2019. The Government filed an appeal on April 10
    and the next day requested an emergency stay pending
    appeal. In accordance with our regular procedures, our April
    motions panel heard the Government’s request for an
    emergency stay. The motions panel held oral argument on
    the stay on April 24. In three written opinions, the panel
    INNOVATION LAW LAB V. WOLF                   17
    unanimously granted the emergency stay on May 7.
    Innovation Law Lab v. McAleenan, 
    924 F.3d 503
     (9th Cir.
    2019).
    In a per curiam opinion, the motions panel disagreed, by
    a vote of two to one, with the district court’s holding that
    plaintiffs were likely to succeed in their statutory argument
    that the MPP is inconsistent with 
    8 U.S.C. § 1225
    (b). 
    Id.
    at 508–09. The panel majority stated its legal conclusion in
    tentative terms, writing that it was “doubtful that subsection
    (b)(1) [of § 1225] ‘applies’ to [plaintiffs.]” Id. at 509
    (emphasis added).
    Judge Watford concurred in the per curiam opinion but
    wrote separately to express concern that the MPP is arbitrary
    and capricious because it lacks sufficient non-refoulement
    protections. Id. at 511 (Watford, J., concurring). Judge
    Watford expressed concern that asylum officers do not ask
    asylum applicants whether they have a fear of returning to
    Mexico: “One suspects the agency is not asking an important
    question during the interview process simply because it
    would prefer not to hear the answer.” Id. Judge Watford
    concluded, “DHS’s policy is virtually guaranteed to result in
    some number of applicants being returned to Mexico in
    violation of the United States’ non-refoulement obligations.”
    Id.
    Judge Fletcher concurred only in the result. He wrote
    separately, arguing that the MPP was inconsistent with
    
    8 U.S.C. § 1225
    (b). 
    Id. at 512
     (W. Fletcher, J., concurring in
    the result). In his view, asylum seekers subject to the MPP
    are properly characterized as applicants under § 1225(b)(1)
    rather than § 1225(b)(2), and are thus protected against being
    returned to Mexico pending adjudication of their applications.
    18             INNOVATION LAW LAB V. WOLF
    Judge Fletcher emphasized the preliminary nature of the
    emergency stay proceedings before the motions panel,
    writing, “I am hopeful that the regular argument panel that
    will ultimately hear the appeal, with the benefit of full
    briefing and regularly scheduled argument, will be able to see
    the Government’s arguments for what they are—baseless
    arguments in support of an illegal policy[.]” Id. at 518.
    IV. Standard of Review
    When deciding whether to issue a preliminary injunction,
    a district court considers whether the requesting party has
    shown “that he is likely to succeed on the merits, that he is
    likely to suffer irreparable harm in the absence of preliminary
    relief, that the balance of equities tips in his favor, and that an
    injunction is in the public interest.” Winter v. Nat. Res. Def.
    Council, Inc., 
    555 U.S. 7
    , 20 (2008). Likelihood of success
    on the merits is a threshold inquiry and the most important
    factor. See, e.g., Edge v. City of Everett, 
    929 F.3d 657
    , 663
    (9th Cir. 2019).
    We review a grant of a preliminary injunction for abuse
    of discretion. See, e.g., United States v. California, 
    921 F.3d 865
    , 877 (9th Cir. 2019). “The district court’s interpretation
    of the underlying legal principles, however, is subject to de
    novo review and a district court abuses its discretion when it
    makes an error of law.” Sw. Voter Registration Educ. Project
    v. Shelley, 
    344 F.3d 914
    , 918 (9th Cir. 2003) (en banc).
    INNOVATION LAW LAB V. WOLF                   19
    V. Likelihood of Success on the Merits
    A. Effect of the Motions Panel’s Decision
    A preliminary question is whether a merits panel is bound
    by the analysis of a motions panel on a question of law,
    performed in the course of deciding an emergency request for
    a stay pending appeal. On that question, we follow East Bay
    Sanctuary Covenant v. Trump, Nos. 18-17274 and 18-17436
    (9th Cir. 2020), argued on the same day as this case, in which
    we held that a motions panel’s legal analysis, performed
    during the course of deciding an emergency motion for a stay,
    is not binding on later merits panels. Such a decision by a
    motions panel is “a probabilistic endeavor,” “doctrinally
    distinct” from the question considered by the later merits
    panel, and “issued without oral argument, on limited
    timelines, and in reliance on limited briefing.” 
    Id.
     at 21–22,
    20. “Such a predictive analysis should not, and does not,
    forever bind the merits of the parties’ claims.” Id. at 22. At
    oral argument in this case, the Government acknowledged
    “that law of the circuit treatment does not apply to [the
    motion’s panel’s decision].” The Government later reiterated
    that it was “not advocating for law of the circuit treatment.”
    The Government “agree[d] that that is inappropriate in the
    context of a motions panel decision.”
    Even if, acting as a merits panel, we may be bound in
    some circumstances by a decision by a motions panel on a
    legal question, we would in any event not be bound in the
    case now before us. Two of the three judges on the motions
    panel disagreed in part with the Government’s legal
    arguments in support of the MPP. Further, the motions
    panel’s per curiam opinion did not purport to decide
    definitively the legal questions presented to it in the
    20            INNOVATION LAW LAB V. WOLF
    emergency stay motion. The per curiam spoke in terms of
    doubt and likelihood, rather than in terms of definitive
    holdings. Innovation Law Lab, 924 F.3d at 509; see also
    supra Part III. Indeed, Judge Fletcher, who concurred in
    granting the emergency stay, specifically addressed the effect
    of the legal analysis of the motions panel and expressed the
    hope that the merits panel, with the benefit of full briefing
    and argument, would decide the legal questions differently.
    B. Questions on the Merits
    Plaintiffs challenge two aspects of the MPP. First, they
    challenge the requirement that asylum seekers return to
    Mexico and wait there while their applications for asylum are
    adjudicated.     They contend that this requirement is
    inconsistent with the INA, as amended in 1996 by the Illegal
    Immigration Reform and Immigrant Responsbility Act
    (“IIRIRA”). Second, in the alternative, they challenge the
    failure of asylum officers to ask asylum seekers whether they
    fear being returned to Mexico. They contend that this failure
    is inconsistent with our treaty-based non-refoulement
    obligations. They contend, further, that with respect to non-
    refoulement, the MPP should have been adopted only after
    notice-and-comment rulemaking.
    We address these challenges in turn. We conclude that
    plaintiffs have shown a likelihood of success on their claim
    that the return-to-Mexico requirement of the MPP is
    inconsistent with 
    8 U.S.C. § 1225
    (b). We further conclude
    that plaintiffs have shown a likelihood of success on their
    claim that the MPP does not comply with our treaty-based
    non-refoulement obligations codified at 
    8 U.S.C. § 1231
    (b).
    We do not reach the question whether they have shown a
    likelihood of success on their claim that the anti-refoulement
    INNOVATION LAW LAB V. WOLF                  21
    aspect of the MPP should have been adopted through notice-
    and-comment rulemaking.
    1. Return to Mexico
    The essential feature of the MPP is that non-Mexican
    asylum seekers who arrive at a port of entry along the United
    States’ southern border must be returned to Mexico to wait
    while their asylum applications are adjudicated. Plaintiffs
    contend that the requirement that they wait in Mexico is
    inconsistent with 
    8 U.S.C. § 1225
    (b). The government
    contends, to the contrary, that the MPP is consistent with
    § 1225(b).
    The relevant text of § 1225 is as follows:
    (a) Inspection
    (1) Aliens treated as applicants for
    admission
    An alien present in the United States
    who has not been admitted . . . shall be
    deemed for purposes of this chapter an
    applicant for admission.
    ...
    (b) Inspection of applicants for admission
    (1) Inspection of aliens arriving in the
    United States and certain other
    aliens who have not been admitted
    or paroled
    22   INNOVATION LAW LAB V. WOLF
    (A)         Screening
    (i) In general
    If an immigration officer
    determines that an alien . . . who is
    arriving in the United States . . . is
    inadmissible under section
    1182(a)(6)(C) or 1182(a)(7) of this
    title, the officer shall order the
    alien removed from the United
    States without further hearing or
    review unless the alien indicates
    either an intention to apply for
    asylum under section 1158 of this
    title or a fear of persecution.
    (ii) Claims for asylum
    If an immigration officer
    determines that an alien . . . is
    inadmissible under section
    1182(a)(6)(C) or 1182(a)(7) of this
    title and the alien indicates either
    an intention to apply for asylum
    under section 1158 of this title or
    a fear of persecution, the officer
    shall refer the alien for an
    interview by an asylum officer
    under subparagraph (B).
    ...
    (B)         Asylum interviews
    INNOVATION LAW LAB V. WOLF                    23
    ...
    (ii) Referral of certain aliens
    If the [asylum] officer
    determines at the time of the
    interview that an alien has a
    credible fear of persecution . . . ,
    the alien shall be detained for
    further consideration of the
    application for asylum.
    ...
    (2) Inspection of other aliens
    (A)         In general
    Subject to subparagraphs (B) and
    (C), in the case of an alien who is an
    applicant for admission, if the
    examining immigration officer
    determines that an alien seeking
    admission is not clearly and beyond a
    doubt entitled to be admitted, the alien
    shall be detained for a proceeding
    under section 1229a of this title.
    (B)         Exception
    Subparagraph (A) shall not apply
    to an alien —
    (i)         who is a crewman
    24            INNOVATION LAW LAB V. WOLF
    (ii)      to whom paragraph (1)
    applies, or
    (iii)     who is a stowaway.
    (C)          Treatment of aliens arriving
    from contiguous territory
    In the case of an alien described in
    subparagraph (A) who is arriving on
    land (whether or not at a designated
    port of arrival) from a foreign territory
    contiguous to the United States, the
    Attorney General may return the alien
    to that territory pending a proceeding
    under section 1229a of this title.
    There are two categories of “applicants for admission”
    under § 1225. § 1225(a). First, there are applicants described
    in § 1225(b)(1). Second, there are applicants described in
    § 1225(b)(2).
    Applicants described in § 1225(b)(1) are inadmissible
    based on either of two grounds, both of which relate to their
    documents or lack thereof. Applicants described in
    § 1225(b)(2) are in an entirely separate category. In the
    words of the statute, they are “other aliens.” § 1225(b)(2)
    (heading). Put differently, again in the words of the statute,
    § (b)(2) applicants are applicants “to whom paragraph
    [(b)](1)” does not apply. § 1225(b)(2)(B)(ii). That is,
    § (b)(1) applicants are those who are inadmissible on either
    of the two grounds specified in that subsection. Section
    (b)(2) applicants are all other inadmissible applicants.
    INNOVATION LAW LAB V. WOLF                     25
    Section (b)(1) applicants are more numerous than § (b)(2)
    applicants, but § (b)(2) is a broader category in the sense that
    § (b)(2) applicants are inadmissible on more grounds than
    § (b)(1) applicants. Inadmissable applicants under § (b)(1)
    are aliens traveling with fraudulent documents
    (§ 1182(a)(6)(C)) or no documents (§ 1182(a)(7)). By
    contrast, inadmissable applicants under § (b)(2) include, inter
    alia, aliens with “a communicable disease of public health
    significance” or who are “drug abuser[s] or addict[s]”
    (§ 1182(a)(1)(A)(i), (iv)); aliens who have “committed . . . a
    crime involving moral turpitude” or who have “violat[ed] . . .
    any law or regulation . . . relating to a controlled substance”
    (§ 1182(a)(2)(A)(i)); aliens who “seek to enter the United
    States . . . to violate any law of the United States relating to
    espionage or sabotage,” or who have “engaged in a terrorist
    activity” (§ 1182(a)(3)(A), (B)); aliens who are “likely . . . to
    become a public charge” (§ 1182(a)(4)(A)); and aliens who
    are alien “smugglers” (§ 1182(a)(6)(E)).
    The Supreme Court recently distinguished § (b)(1) and
    § (b)(2) applicants, stating unambiguously that they fall into
    two separate categories:
    [A]pplicants for admission fall into one of two
    categories, those covered by § 1225(b)(1) and
    those covered by § 1225(b)(2). Section
    1225(b)(1) applies to aliens initially
    determined to be inadmissible due to fraud,
    misrepresentation, or lack of valid
    documentation. . . . Section 1225(b)(2) is
    broader. It serves as a catchall provision that
    applies to all applicants for admission not
    covered by § 1225(b)(1).
    26           INNOVATION LAW LAB V. WOLF
    Jennings v. Rodriguez, 
    138 S. Ct. 830
    , 837 (2018) (emphasis
    added) (citations omitted).
    Even more recently, the Attorney General of the United
    States, through the Board of Immigration Appeals, drew the
    same distinction and briefly described the procedures
    applicable to the two categories:
    Under section 235 of the Act [
    8 U.S.C. § 1225
    ], all aliens “arriv[ing] in the United
    States” or “present in the United States
    [without having] been admitted” are
    considered “applicants for admission,” who
    “shall be inspected by immigration officers.”
    INA § 235(a)(1), (3). [
    8 U.S.C. § 1225
    (a)(1),
    (3).] In most cases, those inspections yield
    one of three outcomes. First, if an alien is
    “clearly and beyond a doubt entitled to be
    admitted,” he will be permitted to enter, or
    remain in, the country without further
    proceedings. 
    Id.
     § 235(b)(2)(A). [
    8 U.S.C. § 1225
    (b)(2)(A).] Second, if the alien is not
    clearly admissible, then, generally, he will be
    placed in “proceeding[s] under section 240
    [8 U.S.C. § 1229a]” of the Act—that is, full
    removal proceedings. Id. Third, if the alien is
    inadmissible on one of two specified grounds
    and meets certain additional criteria, DHS
    may place him in either expedited or full
    proceedings. Id. § 235(b)(1)(A)(i) [
    8 U.S.C. § 1225
    (b)(1)(A)(i)]; see Matter of E-R-M- &
    L-R-M-, 
    25 I&N Dec. 520
    , 524 (BIA 2011).
    INNOVATION LAW LAB V. WOLF                     27
    Matter of M-S-, 
    27 I. & N. Dec. 509
    , 510 (BIA April 16,
    2019).
    The procedures specific to the two categories of
    applicants are outlined in their respective subsections. To
    some extent, the statutorily prescribed procedures are the
    same for both categories. If a § (b)(1) applicant passes his or
    her credible fear interview, he or she will be placed in regular
    removal proceedings under 8 U.S.C. § 1229a. See 
    8 C.F.R. § 208.30
    (f). A § (b)(1) applicant may also be placed directly
    into regular removal proceedings under § 1229a at the
    discretion of the Government. See Matter of E-R-M- & L-R-
    M-, 
    25 I. & N. Dec. 520
    , 522 (BIA 2011). A § (b)(2)
    applicant who is “not clearly and beyond a doubt entitled to
    be admitted” is automatically placed in regular removal
    proceedings under § 1229a. See § 1225(b)(2)(A).
    Both § (b)(1) and § (b)(2) applicants can thus be placed
    in regular removal proceedings under § 1229a, though by
    different routes. But the fact that an applicant is in removal
    proceedings under § 1229a does not change his or her
    underlying category. A § (b)(1) applicant does not become
    a § (b)(2) applicant, or vice versa, by virtue of being placed
    in a removal proceeding under § 1229a.
    However, the statutory procedures for the two categories
    are not identical. Some of the procedures are exclusive to one
    category or the other. For example, if a § (b)(1) applicant
    fails to pass his or her credible fear interview, he or she may
    be removed in an expedited proceeding without a regular
    removal proceeding under § 1229a. See § 1225(b)(1)(A), (B).
    There is no comparable procedure specified in § (b)(2) for
    expedited removal of a § (b)(2) applicant. Further, in some
    circumstances a § (b)(2) applicant may be “returned” to a
    28             INNOVATION LAW LAB V. WOLF
    “territory contiguous to the United States” pending his or her
    regular removal proceeding under § 1229a.                 See
    § 1225(b)(2)(C). There is no comparable “return” procedure
    specified in §1225(b)(1) for a § (b)(1) applicant.
    The statutory question posed by the MPP is whether a
    § (b)(1) applicant may be “returned” to a contiguous territory
    under § 1225(b)(2)(C). That is, may a § (b)(1) applicant be
    subjected to a procedure specified for a § (b)(2) applicant? A
    plain-meaning reading of § 1225(b)—as well as the
    Government’s longstanding and consistent practice up until
    now—tell us that the answer is “no.”
    There is nothing in § 1225(b)(1) to indicate that a § (b)(1)
    applicant may be “returned” under § 1225(b)(2)(C). Section
    (b)(1)(A)(i) tells us with respect to § (b)(1) applicants that an
    “officer shall order the alien removed . . . without further
    hearing or review unless the alien indicates either an intention
    to apply for asylum . . . or a fear of persecution.” Section
    (b)(1)(A)(ii) tells us that § (b)(1) applicants who indicate an
    intention to apply for asylum or a fear of persecution “shall”
    be referred by the immigration officer to an “asylum officer”
    for an interview. The remainder of § 1225(b)(1) specifies
    what happens to a § (b)(1) applicant depending on the
    determination of the asylum officer—either expedited
    removal or detention pending further consideration.
    § 1225(b)(1)(B)(ii)–(iii). There is nothing in § 1225(b)(1)
    stating, or even suggesting, that a § (b)(1) applicant is subject
    to the “return” procedure of § 1225(b)(2)(C).
    Nor is there anything in § 1225(b)(2) to indicate that a
    § (b)(1) applicant may be “returned” under § 1225(b)(2)(C).
    Taking § 1225(b)(2) subparagraph by subparagraph, it
    provides as follows. Subparagraph (A) tells us that unless a
    INNOVATION LAW LAB V. WOLF                     29
    § (b)(2) applicant is “clearly and beyond a doubt entitled to
    be admitted,” she or he “shall be detained” for a removal
    proceeding under § 1229a. § 1225(b)(2)(A). Subparagraph
    (A) is “[s]ubject to subparagraphs (B) and (C).” Id.
    Subparagraph (B) tells us that subparagraph (A) does not
    apply to three categories of aliens—“crewm[e]n,” § (b)(1)
    applicants, and “stowaway[s].” § 1225(b)(2)(B). Finally,
    subparagraph (C) tells us that a § (b)(2) applicant who arrives
    “on land . . . from a foreign territory contiguous to the United
    States,” instead of being “detained” under subparagraph (A)
    pending his or her removal proceeding under § 1229a, may be
    “returned” to that contiguous territory pending that
    proceeding. § 1225(b)(2)(C). Section (b)(1) applicants are
    mentioned only once in § 1225(b)(2), in subparagraph (B)(ii).
    That subparagraph specifies that subparagraph (A)—which
    automatically entitles § (b)(2) applicants to regular removal
    proceedings under § 1229a—does not apply to § (b)(1)
    applicants.
    The “return-to-a-contiguous-territory” provision of
    § 1225(b)(2)(C) is thus available only for § (b)(2) applicants.
    There is no plausible way to read the statute otherwise.
    Under a plain-meaning reading of the text, as well as the
    Government’s longstanding and consistent practice, the
    statutory authority upon which the Government now relies
    simply does not exist.
    The Government nonetheless contends that § (b)(2)(C)
    authorizes the return to Mexico not only of § (b)(2)
    applicants, but also of § (b)(1) applicants. The Government
    makes essentially three arguments in support of this
    contention. None is persuasive.
    30             INNOVATION LAW LAB V. WOLF
    First, the Government argues that § (b)(1) applicants are
    a subset of § (b)(2) applicants. Blue Brief at 35. Under the
    Government’s argument, there are § (b)(1) applicants, defined
    in § (b)(1), and there are § (b)(2) applicants, defined as all
    applicants, including § (b)(2) and § (b)(1) applicants. The
    Government argues that DHS, in its discretion, can therefore
    apply the procedures specified in § (b)(2) to a § (b)(1)
    applicant. That is, as stated in its brief, the Government has
    “discretion to make the initial ‘determin[ation]’ whether to
    apply section 1225(b)(1) or section 1225(b)(2) to a given
    alien.” Blue Brief at 30.
    The Government’s argument ignores the statutory text,
    the Supreme Court’s opinion in Jennings, and the opinion of
    its own Attorney General in Matter of M-S-. The text of
    § 1225(b) tells us that § (b)(1) and § (b)(2) are separate and
    non-overlapping categories. In Jennings, the Supreme Court
    told us explicitly that § (b)(1) and § (b)(2) applicants fall into
    separate and non-overlapping categories. In Matter of M-S-,
    the Attorney General wrote that applicants are subject to
    different procedures depending on whether they are § (b)(1)
    or § (b)(2) applicants.
    Second, the Government argues that § (b)(2)(B)(ii) allows
    DHS, in its discretion, to “apply” to a § (b)(1) applicant either
    procedures described in § (b)(1) or those described in
    § (b)(2). The Government’s second argument is necessitated
    by its first. To understand the Government’s second
    argument, one must keep in mind that § (b)(2)(A)
    automatically entitles a § (b)(2) applicant to a regular removal
    hearing under § 1229a. But we know from § (b)(1) that not
    all § (b)(1) applicants are entitled to a removal hearing under
    § 1229a. Having argued that § (b)(2) applicants include not
    only § (b)(2) but also § (b)(1) applicants, the Government
    INNOVATION LAW LAB V. WOLF                      31
    needs some way to avoid giving regular removal proceedings
    to all § (b)(1) applicants. The best the Government can do is
    to rely on § (b)(2)(B)(ii), which provides: “Subparagraph (A)
    shall not apply to an alien . . . to whom paragraph [(b)](1)
    applies.” § 1225(b)(2)(B)(ii) (emphasis added). The
    Government thus argues that § (b)(2)(B)(ii) allows DHS, in
    its discretion, to “apply,” or not apply, § (b)(2)(A) to a
    § (b)(1) applicant.
    The Government misreads § (b)(2)(B)(ii). Subparagraph
    (B) tells us, “Subparagraph (A) shall not apply to an alien —
    (i) who is a crewman, (ii) to whom paragraph [(b)](1) applies,
    or (iii) who is a stowaway.” The function of § (b)(2)(B)(ii)
    is to make sure that we understand that the automatic
    entitlement to a regular removal hearing under § 1229a,
    specified in § (b)(2)(A) for a § (b)(2) applicant, does not
    apply to a § (b)(1) applicant. However, the Government
    argues that § (b)(2)(B)(ii) authorizes the Government to
    perform an act. That act is to “apply” the expedited removal
    procedures of § (b)(1) to some of the aliens under § (b)(2), as
    the Government defines § (b)(2) applicants.
    There is a fatal syntactical problem with the
    Government’s argument. “Apply” is used twice in the same
    sentence in § (b)(2)(B)(ii). The first time the word is used, in
    the lead-in to the section, it refers to the application of a
    statutory section (“Subparagraph (A) shall not apply”). The
    second time the word is used, it is used in the same manner,
    again referring to the application of a statutory section (“to
    whom paragraph [(b)](1) applies”). When the word is used
    the first time, it tells us that subparagraph (A) shall not apply.
    When the word is used the second time, it tells us to whom
    subparagraph (A) shall not apply: it does not apply to
    applicants to whom § (b)(1) applies. The word is used in the
    32            INNOVATION LAW LAB V. WOLF
    same manner both times to refer to the application of
    subparagraph (A). The word is not used the first time to refer
    to the application of a subparagraph (A), and the second time
    to an action by DHS.
    The Government’s third argument is based on the
    supposed culpability of § (b)(1) applicants. We know from
    § (b)(2)(A) that § (b)(2) applicants are automatically entitled
    to full removal proceedings under § 1229a. However,
    § (b)(2) applicants may be returned to Mexico under
    § (b)(2)(C) to await the outcome of their removal hearing
    under § 1229a. It makes sense for the Government, in its
    discretion, to require some § (b)(2) applicants to remain in
    Mexico while their asylum applications are adjudicated, for
    some § (b)(2) applicants are extremely undesirable
    applicants. As discussed above, § (b)(2) applicants include
    spies, terrorists, alien smugglers, and drug traffickers.
    When the Government was before the motions panel in
    this case, it argued that § (b)(1) applicants are more culpable
    than § (b)(2) applicants and therefore deserve to be forced to
    wait in Mexico while their asylum applications are being
    adjudicated. In its argument to the motions panel, the
    Government compared § (b)(1) and § (b)(2) applicants,
    characterizing § (b)(2) applicants as “less-culpable arriving
    aliens.” The Government argued that returning § (b)(2), but
    not § (b)(1), applicants to a contiguous territory would have
    “the perverse effect of privileging aliens who attempt to
    obtain entry to the United States by fraud . . . over aliens who
    follow our laws.”
    The Government had it exactly backwards. Section (b)(1)
    applicants are those who are “inadmissible under section
    1182(a)(6)(C) or 1182(a)(7)” of Title 8. These two sections
    INNOVATION LAW LAB V. WOLF                    33
    describe applicants who are inadmissible because they lack
    required documents rather than because they have a criminal
    history or otherwise pose a danger to the United States.
    Section 1182(a)(6)(C), entitled “Misrepresentation,” covers,
    inter alia, aliens using fraudulent documents. That is, it
    covers aliens who travel under false documents and who,
    once they arrive at the border or enter the country, apply for
    asylum. Section 1182(a)(7), entitled “Documentation
    requirements,” covers aliens traveling without documents. In
    short, § (b)(1) applies to bona fide asylum applicants, who
    commonly have fraudulent documents or no documents at all.
    Indeed, for many such applicants, fraudulent documents are
    their only means of fleeing persecution, even death, in their
    own countries. The structure of § (b)(1), which contains
    detailed provisions for processing asylum seekers,
    demonstrates that Congress recognized that § (b)(1)
    applicants may have valid asylum claims and should therefore
    receive the procedures specified in § (b)(1).
    In its argument to our merits panel, the Government made
    a version of the same argument it had made earlier to the
    motions panel. After referring to (but not describing) § (b)(2)
    applicants, the Government now argues in its opening brief:
    Section 1225(b)(1), meanwhile, reaches,
    among other classes of aliens, those who
    engage in fraud or willful misrepresentations
    in an attempt to deceive the United States into
    granting an immigration benefit. See 
    8 U.S.C. § 1182
    (a)(6)(C). Plaintiffs have not explained
    why Congress would have wanted that class
    of aliens to be exempt from temporary return
    to Mexico while their full removal
    proceedings are ongoing.
    34            INNOVATION LAW LAB V. WOLF
    Blue Brief at 37–38 (emphasis in original).
    We need not look far to discern Congress’s motivation in
    authorizing return of § (b)(2) applicants but not § (b)(1)
    applicants. Section (b)(2)(C) was added to IIRIRA late in the
    drafting process, in the wake of Matter of Sanchez-Avila,
    
    21 I. & N. Dec. 444
     (BIA 1996). Sanchez-Avila was a
    Mexican national who applied for entry as a “resident alien
    commuter” but who was charged with being inadmissible due
    to his “involvement with controlled substances.” 
    Id. at 445
    ;
    see 
    8 U.S.C. § 1182
    (a)(2)(A)(i) (§ (b)(2) applicants include
    aliens who have “violat[ed] . . . any law or regulation . . .
    relating to a controlled substance”). In order to prevent aliens
    like Sanchez-Avila from staying in the United States during
    the pendency of their guaranteed regular removal proceeding
    under § 1229a, as they would otherwise have a right to do
    under § (b)(2)(A), Congress added § 1225(b)(2)(C).
    Congress had specifically in mind undesirable § (b)(2)
    applicants like Sanchez-Avila. It did not have in mind bona
    fide asylum seekers under § (b)(1).
    We therefore conclude that plaintiffs have shown a
    likelihood of success on the merits of their claim that the
    MPP is inconsistent with 
    8 U.S.C. § 1225
    (b).
    2. Refoulement
    Plaintiffs claim that the MPP is invalid in part, either
    because it violates the United States’ treaty-based anti-
    refoulement obligations, codified at 
    8 U.S.C. § 1231
    (b)(3)(A), or because, with respect to refoulement, the
    MPP was improperly adopted without notice-and-comment
    rulemaking. Our holding that plaintiffs are likely to succeed
    on their claim that the MPP is invalid in its entirety because
    INNOVATION LAW LAB V. WOLF                  35
    it is inconsistent with § 1225(b) makes it unnecessary to
    decide plaintiffs’ second claim. We nonetheless address it as
    an alternative ground, under which we hold the MPP invalid
    in part.
    Refoulement occurs when a government returns aliens to
    a country where their lives or liberty will be threatened on
    account of race, religion, nationality, membership of a
    particular social group, or political opinion. The United
    States is obliged by treaty and implementing statute, as
    described below, to protect against refoulement of aliens
    arriving at our borders.
    Paragraph one of Article 33 of the 1951 United Nations
    Convention Relating to the Status of Refugees, entitled,
    “Prohibition of expulsion or return (‘refoulement’),”
    provides:
    No Contracting State shall expel or return
    (“refouler”) a refugee in any manner
    whatsoever to the frontiers of territories where
    his life or freedom would be threatened on
    account of his race, religion, nationality,
    membership of a particular social group or
    political opinion.
    The United States is not a party to the 1951 Convention, but
    in 1968 we acceded to the United Nations Protocol Relating
    to the Status of Refugees, Jan. 31, 1967. INS v. Stevic,
    
    467 U.S. 407
    , 416 (1984). “The Protocol bound parties to
    comply with the substantive provisions of Articles 2 through
    34 of the United Nations Convention Relating to the Status of
    Refugees.” 
    Id.
     Twelve years later, Congress passed the
    Refugee Act of 1980, implementing our obligations under the
    36             INNOVATION LAW LAB V. WOLF
    1967 Protocol. “If one thing is clear from the legislative
    history of the . . . entire 1980 Act, it is that one of Congress’
    primary purposes was to bring United States refugee law into
    conformance with the 1967 United Nations Protocol Relating
    to the Status of Refugees.” INS v. Cardoza-Fonseca,
    
    480 U.S. 421
    , 436 (1987). The 1980 Act included, among
    other things, a provision designed to implement Article 33 of
    the 1951 Convention. After recounting the history behind
    
    8 U.S.C. § 1253
    (h)(1), part of the 1980 Act, the Supreme
    Court characterized that section as “parallel[ing] Article 33,”
    the anti-refoulement provision of the 1951 Convention. INS
    v. Aguirre-Aguirre, 
    526 U.S. 415
    , 427 (1999).
    Section 1253(h)(1) provided, in relevant part, “The
    Attorney General shall not deport or return any alien . . . to
    a country if the Attorney General determines that such alien’s
    life or freedom would be threatened in such country on
    account of race, religion, nationality, membership of a
    particular social group, or political opinion.” 
    Id. at 419
    (emphasis added). The current version is § 1231(b)(3)(A):
    “[T]he Attorney General may not remove an alien to a
    country if the Attorney General decides that the alien’s life or
    freedom would be threatened in that country because of the
    alien’s race, religion, nationality, membership in a particular
    social group, or political opinion.” (Emphasis added.) The
    words “deport or return” in the 1980 version of the section
    were replaced in 1996 by “remove” as part of a general
    statutory revision under IIRIRA. Throughout IIRIRA,
    “removal” became the new all-purpose word, encompassing
    “deportation,” “exclusion,” and “return” in the earlier statute.
    See, e.g., Salgado-Diaz v. Gonzales, 
    395 F.3d 1158
    , 1162 (9th
    Cir. 2005) (“IIRIRA eliminated the distinction between
    deportation and exclusion proceedings, replacing them with
    a new, consolidated category—‘removal.’”).
    INNOVATION LAW LAB V. WOLF                    37
    Plaintiffs point out several features of the MPP that, in
    their view, provide insufficient protection against
    refoulement.
    First, under the MPP, to stay in the United States during
    the pendency of removal proceedings under § 1229a, the
    asylum seeker must show that it is “more likely than not” that
    he or she will be persecuted in Mexico. More-likely-than-not
    is a high standard, ordinarily applied only after an alien has
    had a regular removal hearing under § 1229a. By contrast,
    the standard ordinarily applied in screening interviews with
    asylum officers at the border is much lower. Aliens subject
    to expedited removal need only establish a “credible fear” in
    order to remain in the United States pending a hearing under
    § 1229a. §§ 1225(b)(1)(A)(ii), 1225(b)(1)(B)(ii). Credible
    fear requires only that the alien show a “significant
    possibility” of persecution. § 1225(b)(1)(B)(v).
    Second, under the MPP, an asylum seeker is not entitled
    to advance notice of, and time to prepare for, the hearing with
    the asylum officer; to advance notice of the criteria the
    asylum officer will use; to the assistance of a lawyer during
    the hearing; or to any review of the asylum officer’s
    determination. By contrast, an asylum seeker in a removal
    proceeding under § 1229a is entitled to advance notice of the
    hearing with sufficient time to prepare; to advance notice of
    the precise charge or charges on which removal is sought; to
    the assistance of a lawyer; to an appeal to the Board of
    Immigration Appeals; and to a subsequent petition for review
    to the court of appeals.
    Third, an asylum officer acting under the MPP does not
    ask an asylum seeker whether he or she fears returning to
    Mexico. Instead, asylum seekers must volunteer, without any
    38            INNOVATION LAW LAB V. WOLF
    prompting, that they fear returning. By contrast, under
    existing regulations, an asylum officer conducting a credible
    fear interview is directed “to elicit all relevant and useful
    information bearing on whether the applicant has a credible
    fear of persecution or torture.” 
    8 C.F.R. § 208.30
    (d). The
    asylum officer is specifically directed to “determine that the
    alien has an understanding of the credible fear determination
    process.” § 208.30(d)(2).
    The Government disagrees with plaintiffs based on two
    arguments. The Government first argues briefly that
    § 1231(b)(3)(A) does not encompass a general anti-
    refoulement obligation. It argues that the protection provided
    by § 1231(b)(3)(A) applies to aliens only after they have been
    ordered removed to their home country at the conclusion of
    a regular removal proceeding under § 1229a. It writes:
    Section 1231(b)(3) codifies a form of
    protection from removal that is available only
    after an alien is adjudged removable. See
    
    8 U.S.C. § 1231
    (b)(3); 8 C.F.R. 1208.16(a).
    Aliens subject to MPP do not receive a final
    order of removal to their home country when
    they are returned (temporarily) to Mexico, and
    so there is no reason why the same procedures
    would apply . . . .
    Blue Brief at 41 (emphasis in original).
    The Government reads § 1231(b)(3)(A) too narrowly.
    Section 1231(b)(3)(A) does indeed apply to regular removal
    proceedings under § 1229a, as evidenced, for example, by
    
    8 C.F.R. § 1208.16
    (a) (discussing, inter alia, the role of the
    Immigration Judge). But its application is not limited to such
    INNOVATION LAW LAB V. WOLF                     39
    proceedings. As described above, and as recognized by the
    Supreme Court, Congress intended § 1253(h)(1), and
    § 1231(b)(3)(A) as its recodified successor, to “parallel”
    Article 33 of the 1951 Convention. Aguirre-Aguirre,
    
    526 U.S. at 427
    . Article 33 is a general anti-refoulement
    provision, applicable whenever an alien might be returned to
    a country where his or her life or freedom might be
    threatened on account of a protected ground. It is not limited
    to instances in which an alien has had a full removal hearing
    with significant procedural protections, as would be the case
    under § 1229a.
    The Government’s second argument is that the MPP
    satisfies our anti-refoulement obligations by providing a
    sufficiently effective method of determining whether aliens
    fear, or have reason to fear, returning to Mexico. In its brief,
    the Government contends that asylum seekers who genuinely
    fear returning to Mexico have “every incentive” affirmatively
    to raise that fear during their interviews with asylum officers,
    and that Mexico is not a dangerous place for non-Mexican
    asylum seekers. The Government writes:
    [N]one of the aliens subject to MPP are
    Mexican nationals fleeing Mexico, and all of
    them voluntarily chose to enter and spend
    time in Mexico en route to the United States.
    Mexico, moreover, has committed to adhering
    to its domestic and international obligations
    regarding refugees. Those considerations
    together strongly suggest that the great
    majority of aliens subject to MPP are not
    more likely than not to face persecution on a
    protected ground or torture, in Mexico. In the
    rare case where an MPP-eligible alien does
    40            INNOVATION LAW LAB V. WOLF
    have a substantial and well-grounded basis for
    claiming that he is likely to be persecuted in
    Mexico, that alien will have every incentive to
    raise that fear at the moment he is told that he
    will be returned.
    Blue Brief at 45. However, the Government points to no
    evidence supporting its speculations either that aliens,
    unprompted and untutored in the law of refoulement, will
    volunteer that they fear returning to Mexico, or that there is
    little danger to non-Mexican aliens in Mexico.
    The Government further asserts, again without supporting
    evidence, that any violence that returned aliens face in
    Mexico is unlikely to be violence on account of a protected
    ground—that is, violence that constitutes persecution. The
    Government writes:
    [T]he basic logic of the contiguous-territory-
    return statute is that aliens generally do not
    face persecution on account of a protected
    status, or torture, in the country from which
    they happen to arrive by land, as opposed to
    the home country from which they may have
    fled. (International law guards against torture
    and persecution on account of a protected
    ground, not random acts of crime or
    generalized violence.)
    Blue Brief at 40–41 (emphasis in original).
    Plaintiffs, who are aliens returned to Mexico under the
    MPP, presented sworn declarations to the district court
    INNOVATION LAW LAB V. WOLF                   41
    directly contradicting the unsupported speculations of the
    Government.
    Several declarants described violence and threats of
    violence in Mexico. Much of the violence was directed at the
    declarants because they were non-Mexican—that is, because
    of their nationality, a protected ground under asylum law.
    Gregory Doe wrote in his declaration:
    I did not feel safe at Benito Juarez [a
    migrant shelter] because the neighbors kept
    trying to attack the migrant community. The
    people who lived near the shelter tried to hurt
    us because they did not want us in their
    country. . . .
    At El Barretal [another migrant shelter], I
    felt a little more secure because we had a high
    wall surrounding us. Even so, one night
    someone threw a tear gas bomb into the
    shelter. When I tried to leave the shelter,
    people in passing cars would often yell insults
    at me like “get out of here, you pinches
    Hondurans,” and other bad words that I do not
    want to repeat.
    Alex Doe wrote:

    Some of the violence in Mexico was threatened by
    persecutors from the aliens’ home countries, and much of that
    violence was on account of protected grounds—political
    opinion, religion, and social group. Gregory Doe wrote:
    I am also afraid the Honduran government
    will find me in Mexico and harm me. Even
    outside the country, the Honduran government
    often works with gangs and criminal networks
    to punish those who oppose their policies. I
    am afraid that they might track me down.

    asylum hearing. If she had asked, I would
    have told her about being stopped by the
    Mexican police and attacked by Mexican
    citizens. I would also have told her I am
    afraid that the people who threatened me in
    Honduras could find me in Mexico . . . .

    This evidence in the record is enough—indeed, far more
    than enough—to establish that the Government’s speculations
    have no factual basis. Amici in this case have filed briefs
    bolstering this already more-than-sufficient evidence. For
    example, Amnesty International USA, the Washington Office
    on Latin America, the Latin America Working Group, and the
    Institute for Women in Migration submitted an amicus brief
    referencing many reliable news reports corroborating the
    stories told by the declarants. We referenced several of those
    reports earlier in our opinion.

    Asylum officers are duty bound to protect
    vulnerable asylum seekers from persecution.
    However, under the MPP, they face a conflict
    between the directives of their departmental
    leaders to follow the MPP and adherence to
    our Nation’s legal commitment to not
    returning the persecuted to a territory where
    they will face persecution. They should not
    be forced to honor departmental directives
    that are fundamentally contrary to the moral
    fabric of our Nation and our international and
    domestic legal obligations.
    Id. at 24.
    Based on the Supreme Court’s conclusion that Congress
    intended in § 1253(h)(1) (the predecessor to § 1231(b)(3)(B))
    to “parallel” the anti-refoulement provision of Article 33 of
    the 1951 Convention, and based on the record in the district
    court, we conclude that plaintiffs have shown a likelihood of
    success on the merits of their claim that the MPP does not
    comply with the United States’ anti-refoulement obligations
    under § 1231(b). We need not, and do not, reach the question
    whether the part of the MPP challenged as inconsistent with
    our anti-refoulement obligations should have been adopted
    through notice-and-comment rulemaking.
    VI. Other Preliminary Injunction Factors
    In addition to likelihood of success on the merits, a court
    must consider the likelihood that the requesting party will
    INNOVATION LAW LAB V. WOLF                     49
    suffer irreparable harm, the balance of the equities, and the
    public interest in determining whether a preliminary
    injunction is justified. Winter, 
    555 U.S. at 20
    . “When the
    government is a party, these last two factors merge.” Drakes
    Bay Oyster Co. v. Jewell, 
    747 F.3d 1073
    , 1092 (9th Cir. 2014)
    (citing Nken v. Holder, 
    556 U.S. 418
    , 435 (2009)).
    There is a significant likelihood that the individual
    plaintiffs will suffer irreparable harm if the MPP is not
    enjoined. Uncontested evidence in the record establishes that
    non-Mexicans returned to Mexico under the MPP risk
    substantial harm, even death, while they await adjudication of
    their applications for asylum.
    The balance of equities favors plaintiffs. On one side is
    the interest of the Government in continuing to follow the
    directives of the MPP. However, the strength of that interest
    is diminished by the likelihood, established above, that the
    MPP is inconsistent with 
    8 U.S.C. §§ 1225
    (b) and 1231(b).
    On the other side is the interest of the plaintiffs. The
    individual plaintiffs risk substantial harm, even death, so long
    as the directives of the MPP are followed, and the
    organizational plaintiffs are hindered in their ability to carry
    out their missions.
    The public interest similarly favors the plaintiffs. We
    agree with East Bay Sanctuary Covenant:
    On the one hand, the public has a “weighty”
    interest “in efficient administration of the
    immigration laws at the border.” Landon v.
    Plasencia, 
    459 U.S. 21
    , 34 (1982). But the
    public also has an interest in ensuring that
    “statutes enacted by [their] representatives”
    50             INNOVATION LAW LAB V. WOLF
    are not imperiled by executive fiat. Maryland
    v. King, 
    567 U.S. 1301
    , 1301 (2012) (Roberts,
    C.J., in chambers).
    932 F.3d at 779 (alteration in original).
    VII. Scope of the Injunction
    The district court issued a preliminary injunction setting
    aside the MPP—that is, enjoining the Government “from
    continuing to implement or expand the ‘Migrant Protection
    Protocols’ as announced in the January 25, 2018 DHS policy
    memorandum and as explicated in further agency
    memoranda.” Innovation Law Lab, 366 F. Supp. 3d at 1130.
    Accepting for purposes of argument that some injunction
    should issue, the Government objects to its scope.
    We recognize that nationwide injunctions have become
    increasingly controversial, but we begin by noting that it is
    something of a misnomer to call the district court’s order in
    this case a “nationwide injunction.” The MPP operates only
    at our southern border and directs the actions of government
    officials only in the four States along that border. Two of
    those states (California and Arizona) are in the Ninth Circuit.
    One of those states (New Mexico) is in the Tenth Circuit.
    One of those states (Texas) is in the Fifth Circuit. In practical
    effect, the district court’s injunction, while setting aside the
    MPP in its entirety, does not operate nationwide.
    For two mutually reinforcing reasons, we conclude that
    the district court did not abuse its discretion in setting aside
    the MPP.
    INNOVATION LAW LAB V. WOLF                     51
    First, plaintiffs have challenged the MPP under the
    Administrative Procedure Act (“APA”). Section 706(2)(A)
    of the APA provides that a “reviewing court shall . . . hold
    unlawful and set aside agency action . . . not in accordance
    with law.” We held, above, that the MPP is “not in
    accordance with” 
    8 U.S.C. § 1225
    (b). Section 706(2)(A)
    directs that in a case where, as here, a reviewing court has
    found the agency action “unlawful,” the court “shall . . . set
    aside [the] agency action.” That is, in a case where
    § 706(2)(A) applies, there is a statutory directive—above and
    beyond the underlying statutory obligation asserted in the
    litigation—telling a reviewing court that its obligation is to
    “set aside” any unlawful agency action.
    There is a presumption (often unstated) in APA cases that
    the offending agency action should be set aside in its entirety
    rather than only in limited geographical areas. “[W]hen a
    reviewing court determines that agency regulations are
    unlawful, the ordinary result is that rules are vacated—not
    that their application to the individual petitioners is
    proscribed.” Regents of the Univ. of Cal. v. U.S. Dep’t of
    Homeland Sec., 908 F3d 476, 511 (9th Cir. 2018) (internal
    quotation marks omitted). “When a court determines that an
    agency’s action failed to follow Congress’s clear mandate the
    appropriate remedy is to vacate that action.” Cal. Wilderness
    Coalition v. U.S. Dep’t of Energy, 
    631 F.3d 1072
    , 1095 (9th
    Cir. 2011); see also United Steel v. Mine Safety & Health
    Admin., 
    925 F.3d 1279
    , 1287 (D.C. Cir. 2019) (“The ordinary
    practice is to vacate unlawful agency action.”); Gen. Chem.
    Corp. v. United States, 
    817 F.2d 844
    , 848 (D.C. Cir. 1987)
    (“The APA requires us to vacate the agency’s decision if it is
    ‘arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law . . . .”).
    52            INNOVATION LAW LAB V. WOLF
    Second, cases implicating immigration policy have a
    particularly strong claim for uniform relief. Federal law
    contemplates a “comprehensive and unified” immigration
    policy. Arizona v. United States, 
    567 U.S. 387
    , 401 (2012).
    “In immigration matters, we have consistently recognized the
    authority of district courts to enjoin unlawful policies on a
    universal basis.” E. Bay Sanctuary Covenant, 932 F.3d
    at 779. We wrote in Regents of the University of California,
    908 F.3d at 511, “A final principle is also relevant: the need
    for uniformity in immigration policy. . . . Allowing uneven
    application of nationwide immigration policy flies in the face
    of these requirements.” We wrote to the same effect in
    Hawaii v. Trump, 
    878 F.3d 662
    , 701 (9th Cir. 2017), rev’d on
    other grounds, 
    138 S. Ct. 2392
     (2018): “Because this case
    implicates immigration policy, a nationwide injunction was
    necessary to give Plaintiffs a full expression of their rights.”
    The Fifth Circuit, one of only two other federal circuits with
    states along our southern border, has held that nationwide
    injunctions are appropriate in immigration cases. In
    sustaining a nationwide injunction in an immigration case, the
    Fifth Circuit wrote, “[T]he Constitution requires ‘an uniform
    Rule of Naturalization’; Congress has instructed that ‘the
    immigration laws of the United States should be enforced
    vigorously and uniformly’; and the Supreme Court has
    described immigration policy as ‘a comprehensive and
    unified system.’” Texas v. United States, 
    809 F.3d 134
    ,
    187–88 (5th Cir. 2015) (emphasis in original; citations
    omitted). In Washington v. Trump, 
    847 F.3d 1151
     (9th Cir.
    2017), we relied on the Fifth Circuit’s decision in Texas to
    sustain the nationwide scope of a temporary restraining order
    in an immigration case. We wrote, “[W]e decline to limit the
    geographic scope of the TRO. The Fifth Circuit has held that
    such a fragmented immigration policy would run afoul of the
    INNOVATION LAW LAB V. WOLF                   53
    constitutional and statutory requirement for uniform
    immigration law and policy.” 
    Id.
     at 1166–67.
    Conclusion
    We conclude that the MPP is inconsistent with 
    8 U.S.C. § 1225
    (b), and that it is inconsistent in part with 
    8 U.S.C. § 1231
    (b). Because the MPP is invalid in its entirety due to
    its inconsistency with § 1225(b), it should be enjoined in its
    entirety. Because plaintiffs have successfully challenged the
    MPP under § 706(2)(A) of the APA, and because the MPP
    directly affects immigration into this country along our
    southern border, the issuance of a temporary injunction
    setting aside the MPP was not an abuse of discretion.
    We lift the emergency stay imposed by the motions panel,
    and we affirm the decision of the district court.
    AFFIRMED.
    FERNANDEZ, Circuit Judge, dissenting:
    I respectfully dissent from the majority opinion because
    I believe that we are bound by the published decision in
    Innovation Law Lab v. McAleenan (Innovation I), 
    924 F.3d 503
     (9th Cir. 2019) (per curiam).
    More specifically, we are bound by both the law of the
    circuit and the law of the case. Of course, the rules that
    animate the former doctrine are not the same as those that
    animate the latter. See Gonzalez v. Arizona, 
    677 F.3d 383
    ,
    389 n.4 (9th Cir. 2012) (en banc).

    As we have said: “Circuit law . . . binds all courts within
    a particular circuit, including the court of appeals itself.
    Thus, the first panel to consider an issue sets the law not only
    for all the inferior courts in the circuit, but also future panels
    of the court of appeals.” Hart v. Massanari, 
    266 F.3d 1155
    ,
    1171 (9th Cir. 2001). Moreover: “Once a panel resolves an
    issue in a precedential opinion, the matter is deemed resolved,
    unless overruled by the court itself sitting en banc, or by the
    Supreme Court.” 
    Id.
     (footnote omitted). Published opinions
    are precedential. See 
    id. at 1177
    ; see also Gonzalez, 667 F.3d
    at 389 n.4. That remains true, even if some later panel is
    satisfied that “arguments have been characterized differently
    or more persuasively by a new litigant,”1 or even if a later
    panel is convinced that the earlier decision was “incorrectly
    decided” and “needs reexamination.”2 And those rules are
    not mere formalities to be nodded to and avoided. Rather,
    “[i]nsofar as there may be factual differences between the
    current case and the earlier one, the court must determine
    whether those differences are material to the application of
    the rule or allow the precedent to be distinguished on a
    principled basis.” Hart, 
    266 F.3d at 1172
    . In this case, there
    are no material differences — in fact, the situation before this
    panel is in every material way the same as that before the
    motions panel. Furthermore, there is no doubt that motions
    panels can publish their opinions,3 even though they do not
    generally do so.4 Once published, there is no difference

    between motions panel opinions and other opinions; all are
    entitled to be considered with the same principles of
    deference by ensuing panels. Thus, any hesitation about
    whether they should be precedential must necessarily come
    before the panel decides to publish, not after. As we held in
    Lair v. Bullock, 
    798 F.3d 736
     (9th Cir. 2015):
    Lair contended at oral argument that a
    motions panel’s decision cannot bind a merits
    panel, and as a result we are not bound by the
    motions panel’s analysis in this case. Not so.
    We have held that motions panels can issue
    published decisions. . . . [W]e are bound by a
    prior three-judge panel’s published opinions,
    and a motions panel’s published opinion binds
    future panels the same as does a merits
    panel’s published opinion.
    
    Id. at 747
     (citations omitted). Therefore, the legal
    determinations in Innovation I are the law of the circuit.
    We have explained the law of the case doctrine as “a
    jurisprudential doctrine under which an appellate court does
    not reconsider matters resolved on a prior appeal.” Jeffries v.
    Wood, 
    114 F.3d 1484
    , 1488–89 (9th Cir. 1997) (en banc),
    overruled on other grounds by Gonzalez, 677 F.3d at 389 n.4.
    While we do have discretion to decline application of the
    doctrine, “[t]he prior decision should be followed unless:
    (1) the decision is clearly erroneous and its enforcement
    would work a manifest injustice, (2) intervening controlling
    authority makes reconsideration appropriate, or
    (3) substantially different evidence was adduced at a
    subsequent trial.” Id. at 1489 (internal quotation marks and
    56                 INNOVATION LAW LAB V. WOLF
    footnote omitted).5 We have also indicated that, in general,
    “our decisions at the preliminary injunction phase do not
    constitute the law of the case,”6 but that is principally because
    the matter is at the preliminary injunction stage and a further
    development of the factual record as the case progresses to its
    conclusion may well require a change in the result.7 Even so,
    decisions “on pure issues of law . . . are binding.” Ranchers
    Cattlemen, 499 F.3d at 1114. Of course, the case at hand has
    not progressed beyond the preliminary injunction stage. It is
    still at that stage, and the factual record has not significantly
    changed between the record at the time of the decision
    regarding the stay motion and the current record. Therefore,
    as I see it, absent one of the listed exceptions, which I do not
    perceive to be involved here, the law of the case doctrine
    would also direct that we are bound by much of the motions
    panel’s decision in Innovation I.
    Applying those doctrines:
    (1) The individuals and the organizational plaintiffs are
    not likely to succeed on the substantive claim that the
    Migrant Protection Protocols directive (the MPP) was not
    5
    The majority seems to add a fourth exception, that is, motions panel
    decisions never constitute the law of the case. That would be strange if
    they can constitute the law of the circuit, which they can.

    (4) I express no opinion on whether the district court
    could issue a narrower injunction targeting the problem
    identified by Judge Watford, that is, the dearth of support for
    the government’s unique rule8 that an alien processed under
    the MPP must spontaneously proclaim his fear of persecution
    or torture in Mexico. See Innovation I, 924 F.3d at 511–12
