    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF PUERTO RICO
    [Hon. Pedro A. Delgado-Hernández, U.S. District Judge]
    Before
    Howard, Chief Judge,
    Torruella and Barron, Circuit Judges.
    Alfredo Fernández-Martínez, with whom Carlos R. Baralt Suárez
    and Gurley & Associates were on brief, for appellant.

    February 28, 2020
    BARRON, Circuit Judge. This appeal arises from a federal
    district court's designation of a magistrate judge to "hear and
    determine" -- pursuant to 
    28 U.S.C. § 636
    (b)(1)(A), a provision of
    the Federal Magistrates Act that provides for limited review by
    the district court -- a motion to appoint a receiver over certain
    commercial properties that are the subject of a foreclosure action
    under Puerto Rico law.   The appellant contends that the motion to
    appoint a receiver cannot be delegated to a magistrate judge under
    § 636(b)(1)(A).   The appellant instead contends that the proper
    delegation of such a motion must be made under § 636(b)(1)(B),
    which permits a magistrate judge merely to issue a report and
    recommendation on the motion, subject to the district court's
    plenary review of any objections. We vacate and remand for further
    proceedings.
    I.
    In early 2007, the appellee, BPP Retail Properties, LLC
    ("BPP"), borrowed over $90 million from Countrywide Commercial
    Real Estate Finance Inc. in order to buy and develop six shopping
    centers across Puerto Rico. Those same six shopping centers served
    as collateral for the loan.
    At some point, the appellant, ML-CFC 2007-6 Puerto Rico
    Properties, LLC ("ML-CFC") became the holder of the loan.       On
    February 9, 2017, ML-CFC brought a foreclosure action against BPP
    - 3 -
    under Puerto Rico law in the United States District Court for the
    District of Puerto Rico, invoking its diversity jurisdiction under
    
    28 U.S.C. § 1332
    .
    ML-CFC alleges that when BPP's loan matured on February
    8, 2012, BPP failed to repay the remaining balance.     The balance
    of the loan, ML-CFC asserts, remains outstanding.
    After filing the foreclosure action in federal court,
    ML-CFC moved for the District Court to appoint a receiver over the
    six real estate properties it sought to recover.     In its motion,
    ML-CFC asserted that it had both a contractual right to the
    appointment of a receiver1 under Puerto Rico law and that a receiver
    1 In the event of a default, the mortgage deeds to each of
    the properties provides:
    Mortgagee shall as a matter of right and
    without regard to the solvency of the
    Mortgagor or the adequacy of the security for
    the indebtedness from Mortgagor to Mortgagee,
    be entitled to the appointment of a receiver
    for all or any part of the Mortgaged Property,
    whether such receivership be incidental to a
    proposed sale of the Mortgaged property or
    otherwise, and Mortgagor hereby consents to
    the appointment of such a receiver and agrees
    that it will not oppose any such appointment.
    Said receiver shall have the broadest powers
    and faculties usually granted to a receiver by
    the court and his/her appointment shall be
    made by the court as a matter of absolute right
    granted to the Mortgagee.
    Moreover, the Assignments of Leases and Rents for         each
    property provides:
    At any time after the occurrence and during
    the continuance of an Event of Default, (i)
    - 4 -
    should be appointed as a matter of equity.                 BPP opposed the motion
    by contending that this Court's precedent did not provide for the
    appointment of receivers solely as a matter of contract and that
    ML-CFC could not show that it was entitled to the appointment of
    a receiver as a matter of equity.
    Initially, the District Court referred ML-CFC's motion
    to appoint a receiver to a magistrate judge for a report and
    recommendation     pursuant        to    
    28 U.S.C. § 636
    (b)(1)(B).           That
    provision permits a district court to refer certain matters to
    magistrate     judges    to    issue      "proposed     findings      of   fact    and
    recommendations for [their] disposition" before entering a final
    order, with de novo review by the district court of all of the
    parties'     objections       to   the        magistrate    judge's    report      and
    recommendation.     On February 6, 2018, however, the District Court
    changed course.         It determined that the motion to appoint a
    receiver is the type of "pretrial matter" that a district court
    may designate a magistrate judge to "hear and determine" pursuant
    Assignee, without waiving such Event of
    Default, at its option, upon notice and
    without regard to the adequacy of the security
    for the Loan Obligations, either in person or
    by agent, upon bringing any action or
    proceeding, by a receiver appointed by a
    court, or otherwise, may take possession of
    the Property and have, hold, manage, lease and
    operate the same on such terms and for such
    period of time as Assignee may deem proper.
    - 5 -
    to § 636(b)(1)(A).         That provision allows district courts to
    "designate a magistrate judge to hear and determine any pretrial
    matter," such that the magistrate judge's ruling is treated as a
    final order that can only be modified by a district court if it
    "is clearly erroneous or contrary to law."           Id.
    BPP opposed this designation on the following ground.
    It pointed out that, although 
    28 U.S.C. § 636
    (b)(1)(A) generally
    authorizes the designation of magistrate judges to "hear and
    determine any pretrial matter," that provision also bars district
    courts from designating magistrate judges to "hear and determine"
    certain enumerated types of motions, notwithstanding that they
    concern    matters     that     are    preliminary         to     the    trial.
    Section 636(b)(1)(A) states in particular that magistrate judges
    may not "hear and determine":
    [M]otion[s]    for    injunctive   relief,  for
    judgment on the pleadings, for summary
    judgment, to dismiss or quash an indictment or
    information made by the defendant, to suppress
    evidence in a criminal case, to dismiss or to
    permit maintenance of a class action, to
    dismiss for failure to state a claim upon
    which   relief    can    be  granted,   and  to
    involuntarily dismiss an action.
    BPP argued that the motion to appoint a receiver in this
    case was encompassed by the exception listed above for a "motion
    for injunctive relief."        Thus, BPP requested that the District
    Court   "revert[]    its   decision"   and   refer    the       motion   to   the
    Magistrate Judge for a report and recommendation pursuant to
    - 6 -
    § 636(b)(1)(B), such that the District Court would then review de
    novo any objections to the Magistrate Judge's recommended findings
    and conclusions.
    The   District     Court   rejected    BPP's   argument.        It
    determined that the motion to appoint a receiver was a "pretrial
    matter" under § 636(b)(1)(A) that was not included in the list of
    excepted motions in that provision, as the District Court found
    that a receivership is not a form of injunctive relief.              In doing
    so,   the   District   Court    concluded   that    the    motion    was   not
    "dispositive of the parties' rights." United States v. High Plains
    Livestock, LLC, No. 15-CV-680 MCA/WPL, 
    2016 WL 10591975
    , at *4
    (D.N.M. Jan. 11, 2016).
    Although   § 636(b)(1)(A)       does    not    use      the    word
    "dispositive" that the District Court invoked, we note that Federal
    Rule of Civil Procedure 72, which purports to set forth the
    appropriate standard of review for magistrate judge rulings, does.
    Specifically, Rule 72(a), which applies to "pretrial matter[s]
    [that are] not dispositive of a party's claim or defense," provides
    that the district court must "modify or set aside any part of" a
    magistrate judge's decision in such a matter when it "is clearly
    erroneous or is contrary to law."       Rule 72(b), meanwhile, provides
    that a magistrate judge must "enter a recommended disposition"
    when assigned "to hear a pretrial matter dispositive of a claim or
    - 7 -
    defense," objections to which the district court "must determine
    de novo."
    On March 29, 2018, the Magistrate Judge entered an
    "Opinion and Order" that granted ML-CFC's motion to appoint a
    receiver for the commercial properties in question. The Magistrate
    Judge decided the matter solely on the basis of ML-CFC's first
    argument -- that the loan agreement entitled it to that appointment
    upon BPP's default -- without reaching the issue of whether ML-CFC
    was entitled to the appointment as a matter of equity.
    At that point, BPP filed motions to stay the appointment
    of a receiver and to appeal the Magistrate Judge's decision to the
    District Court. The District Court denied these motions in a short
    opinion:
    Nothing [BPP] states justifies deviating from
    the court's original ruling on this matter.
    The order granting appointment of a receiver
    was premised on the contractual right as set
    forth in the loan documents coupled with
    evidence of default, which based on the
    court's review of the record, [BPP] did not
    rebut despite ample opportunity to present
    evidence it considered favorable.     In this
    way, two judicial officers have examined the
    evidence:   U.S. Magistrate Judge Marcos E.
    López and the undersigned. But [BPP] failed
    to make the showing necessary to justify the
    stay request it has made, as [ML-CFC] has
    persuasively argued in its opposition, or to
    demonstrate that the Magistrate Judge's
    decision should be set aside. [BPP] signed a
    contract, and must live with the consequences
    of having done so.
    - 8 -
    On April 23, 2018, BPP filed an interlocutory appeal
    pursuant to 
    28 U.S.C. § 1292
    (a)(2), which allows for the immediate
    appeal of "orders appointing receivers" to a court of appeals.
    BPP appeals both the District Court's decision to refer the matter
    to the Magistrate Judge for resolution pursuant to 
    28 U.S.C. § 636
    (b)(1)(A) and the merits of whether a receiver should have
    been appointed pursuant to the contract.          BPP does not appeal the
    denial of its motion for a stay.
    We heard oral argument and asked the parties at that
    time to address an issue not considered in their briefs.                  That
    issue concerned whether, if we disagreed with BPP's contention
    that the appointment of a receiver is a form of "injunctive relief"
    under § 636(b)(1)(A), and held that the Magistrate Judge could be
    designated by the District Court to "hear and determine" the motion
    pursuant to that provision, the Magistrate Judge's determination
    of   that   issue    would    contravene     Article III     of   the   federal
    Constitution,       given    the   limited   review   that     § 636(b)(1)(A)
    empowered the District Court to exercise over that decision.
    Following argument, we then called for two subsequent rounds of
    briefing about the Article III concerns that we had raised at
    argument.   Thus, we have before us BPP's challenge to the District
    Court's statutory authority to refer the motion to appoint a
    receiver to the Magistrate Judge under § 636(b)(1)(A) and BPP's
    challenge to the merits of the ruling granting that motion.               But,
    - 9 -
    we also potentially have before us the lurking Article III issue
    that concerns whether, even if the Magistrate Judge had statutory
    authority under § 636(b)(1)(A) to "hear and determine" the motion,
    the Magistrate Judge was powerless to do so under Article III.
    II.
    We start with BPP's challenge to the District Court's
    statutory authority to designate the Magistrate Judge to "hear and
    determine" the motion to appoint a receiver pursuant to 
    28 U.S.C. § 636
    (b)(1)(A).     We do so because, if that challenge has merit,
    then   we   would   have   no   occasion   to   consider   either   the
    constitutionality of the designation or the merits of the order
    granting the motion to appoint the receiver.       Our review of this
    pure question of law is de novo.    See Williams v. Beemiller, Inc.,
    
    527 F.3d 259
    , 264 (2d Cir. 2008) (noting that challenges to
    referrals under 
    28 U.S.C. § 636
    (b)(1)(A) implicate "questions of
    statutory interpretation" and are thus reviewed de novo).
    BPP argues that "the appointment of a receiver . . .
    should be considered -- both procedurally and substantively -- as
    a preliminary injunction."      BPP then contends that the motion at
    issue is for that reason a motion for "injunctive relief" under
    § 636(b)(1)(A) and thus that a district court may not delegate the
    motion to a magistrate judge to "hear and determine" subject only
    - 10 -
    to its review of whether the magistrate judge's determination was
    clearly erroneous or contrary to law.
    In support of that contention, BPP emphasizes that both
    the issuance of a preliminary injunction and the appointment of a
    receiver are "pre-trial remed[ies] in equity," for which the
    standard of review is abuse of discretion.     And, BPP points out,
    Congress permits parties to take interlocutory appeals with regard
    to "orders appointing receivers, or refusing orders to wind up
    receiverships or to take steps to accomplish the purposes thereof,
    such as directing sales or other disposals of property," 
    28 U.S.C. § 1292
    (a)(2), much the same as Congress permits parties to do with
    regard to preliminary injunctions.
    But, BPP provides us with no precedential support for
    the contention that the appointment of a receiver has historically
    been viewed as a form of injunctive relief, and, in Highland Ave.
    & B.R. Co. v. Columbian Equipment Co., 
    168 U.S. 627
     (1898), the
    United States Supreme Court indicated otherwise.   There, the Court
    considered whether, under a statute that permitted parties to file
    interlocutory   appeals   of   decisions    "granting,   continuing,
    refusing, dissolving, or refusing to dissolve an injunction to the
    circuit court of appeals," a party could file an interlocutory
    appeal of an order appointing a receiver.   
    Id. at 629-30
     (emphasis
    added).   The Court concluded that an interlocutory appeal could
    - 11 -
    not be taken from an order appointing a receiver under that statute
    because injunctions and receiverships:
    are, in the common understanding of the
    profession,    entirely   independent.      The
    distinction between the two is clearly
    recognized in the text-books and in the
    reports.     We have separate treatises on
    injunctions and on receivers. The separation
    between them is one which runs through the
    law, and while it is true that the mandatory
    features which, either expressly or by
    implication,     attend    orders    appointing
    receivers, are sometimes made the matter of
    discussion in treatises on receivers, or the
    subject of comment in decisions concerning
    receivers, yet the distinction is never
    forgotten. Familiar, as it must be assumed to
    have been, with this generally recognized
    distinction, congress, if it had intended that
    appeals   should    be  allowed   from   orders
    appointing receivers, as from orders in
    respect to injunctions, would doubtless have
    expressly named such orders.
    
    Id. at 631
    .
    It is true that 
    28 U.S.C. § 636
    (b)(1)(A) uses the phrase
    "injunctive relief" rather than the word "injunction."        But, that
    terminological choice alone does not persuade us that Congress
    intended to encompass an order to appoint a receiver within the
    phrase "injunctive relief" when it is clear that, according to
    Highland, such an order has traditionally been viewed as different
    from an injunction along a number of dimensions.         In fact, BPP's
    own   argument   about   the   current   interlocutory   appeal   statute
    demonstrates that Congress continues to differentiate between the
    issuance of an injunction and the appointment of a receiver.         See
    - 12 -
    
    28 U.S.C. § 1292
    (a)(1) (providing for interlocutory appeals of
    orders relating to injunctions); 
    id.
     § 1292(a)(2) (providing for
    interlocutory of appeals relating to receiverships).
    Nevertheless, we conclude that there is a distinct but
    closely related basis for deciding that the District Court's
    referral of the motion to the Magistrate Judge to "hear and
    determine" subject only to limited review was impermissible.         That
    neither of the parties developed this argument -- until one of
    them referenced it in their reply brief filed in connection with
    the second round of supplemental briefing -- does not prevent us
    from ruling on this basis, especially given that doing so obviates
    the need for us to address a constitutional question arising under
    Article III.   See U.S. Nat. Bank of Or. v. Indep. Ins. Agents of
    Am., Inc., 
    508 U.S. 439
    , 447 (1993) ("[A] court may consider an
    issue 'antecedent to . . . and ultimately dispositive of' the
    dispute before it, even an issue the parties fail to identify and
    brief." (second alteration in original) (quoting Arcadia v. Ohio
    Power Co., 
    498 U.S. 73
    , 77 (1990))); Kamen v. Kemper Fin. Servs.,
    Inc., 
    500 U.S. 90
    , 99 (1991) ("When an issue or claim is properly
    before the court, the court is not limited to the particular legal
    theories   advanced   by   the   parties,   but   rather   retains    the
    independent power to identify and apply the proper construction of
    governing law."); The Anaconda v. Am. Sugar Ref. Co., 
    322 U.S. 42
    ,
    - 13 -
    46 (1944) (noting that parties "can not stipulate away" what
    "Congress has so declared").
    That distinct basis for so ruling rests on our prior
    precedent, which accords with the precedents of other courts,
    addressing the relationship between 
    28 U.S.C. § 636
    (b)(1) and
    Federal Rule of Civil Procedure 72.              As we will explain, that body
    of precedent construes § 636(b)(1) and Rule 72 in a manner that
    ensures that magistrate judges may act on what Rule 72(b) refers
    to   as   "dispositive"      motions       only    by   issuing    reports    and
    recommendations, with any objections to those recommendations
    subject   to    de   novo   review    by   the     district   court,   and   that
    magistrate judges may "hear and determine," subject to more limited
    review by the district court, only what Rule 72(a) refers to as
    "nondispositive" motions.
    In the first of our decisions in this line of authority,
    Phinney v. Wentworth Douglas Hospital, 
    199 F.3d 1
    , 5 (1st Cir.
    1999), we held that a motion for discovery sanctions could, in
    some circumstances, be delegated to a magistrate judge to "hear
    and determine" as a "pretrial matter" under § 636(b)(1)(A), such
    that it would be reviewed only for being clearly erroneous or
    contrary to law, just as Rule 72(a) contemplates may be the case
    for motions it terms "nondispositive."              We explained that Rule 72
    augmented      the   provisions      in    the     Federal    Magistrates    Act,
    "mirror[ing] the standard-of-review taxonomy described in section
    - 14 -
    636(b)(1)," id., by providing "that a magistrate's order on a
    nondispositive motion shall be modified or set aside by the
    district court only if 'found to be clearly erroneous or contrary
    to law,'" but that "if a party contests a magistrate's proposed
    findings and recommendations on a dispositive motion, the district
    judge must 'make a de novo determination,'" id. (emphases added)
    (quoting Fed. R. Civ. P. 72). We further explained "that the terms
    dispositive and nondispositive as used in Rule 72 must be construed
    in harmony with the classifications limned in section 636(b)(1),"
    id., and that, in consequence, the "dispositive motions" referred
    to in Rule 72 were not only "those excepted motions specifically
    enumerated in section 636(b)(1)(A), and no others," id.     Rather,
    we clarified that the "enumeration" of motions in § 636(b)(1)(A)
    "informs the classification of other motions as dispositive or
    nondispositive," id. at 6, such that they, too, would be subject
    to the standard of review for such motions prescribed by Rule 72.
    Against that background, we held that the motion for
    discovery sanctions at issue had been properly delegated under
    § 636(b)(1)(A) and Rule 72(a) because the magistrate judge acted
    on the motion by imposing only a small monetary sanction.    Id.   We
    did so because such a motion was not expressly "excepted under 
    28 U.S.C. § 636
    (b)(1)(A)" and, given the sanction ultimately issued,
    was not of a type that, "in general," was "of the same genre of
    the enumerated motions."   
    Id.
       Accordingly, we treated that motion
    - 15 -
    as "nondispositive" within the meaning of Rule 72(a), thereby
    ensuring that the delegation to a magistrate judge to "hear and
    determine" the motion, subject only to limited review by a district
    court, would be in harmony with that part of Rule 72.                 We noted,
    though, that a motion for discovery sanctions might be subject to
    Rule 72(b), notwithstanding that it was not specifically excepted
    from   § 636(b)(1)(A),       in   the     event   that   "a   magistrate     judge
    aspire[d] to impose a sanction that fully dispose[d] of a claim or
    defense,"    id.,       apparently   on   the     understanding   that   such    a
    resolution    of    a    discovery   sanctions      motion    necessarily   would
    render the motion a "dispositive" one within the meaning of Rule
    72(b), thereby implicating the requirements of that part of Rule
    72.
    We then drew upon Phinney's reasoning in PowerShare,
    Inc. v. Syntel, Inc., 
    597 F.3d 10
    , 13-14 (1st Cir. 2010).                   We did
    so in ruling that a motion to stay litigation pending arbitration
    was a "pretrial matter" that could be delegated to a magistrate
    judge for a final decision under 
    28 U.S.C. § 636
    (b)(1)(A), subject
    only to review by the district court of whether that decision was
    clearly erroneous or contrary to law.               See 
    id. at 14
    .    And, once
    again, we did so because we determined that such a motion was not
    "dispositive" within the meaning of Rule 72(b).                See 
    id.
       We made
    sure to note, however, that, pursuant to our approach in Phinney,
    the list of "[d]ispositive" motions in § 636(b)(1)(A) that may not
    - 16 -
    be delegated to a magistrate judge to "hear and determine" pursuant
    to that provision is "not exhaustive" of the category, such that
    Rule 72(b)'s de novo standard of review for "dispositive" motions
    might apply to a motion that does not appear on the list, due to
    constitutional     concerns      associated       with    allowing     "magistrate
    judges . . . [to] decide motions that are dispositive either of a
    case or of a claim or defense within a case."                  Id. at 13.
    Indeed, other courts have similarly recognized that the
    "[t]he duty to avoid constitutional difficulties when interpreting
    a statute warrants a narrow reading of the matters in which a
    magistrate judge may enter orders without de novo Article III
    review."    Davidson v. Georgia-Pacific, L.L.C., 
    819 F.3d 758
    , 763
    (5th Cir. 2016).       On that basis, they, too, have favored a
    construction of § 636(b)(1)(A) that harmonizes it with Rule 72's
    distinction      between   the         treatment     of        "dispositive"      and
    "nondispositive"    motions      and    its     concomitant      use   of   distinct
    standards   of   review    for    each    type.          See    id.;   Mitchell   v.
    Valenzuela, 
    791 F.3d 1166
    , 1168-69 (9th Cir. 2015) ("To determine
    whether a motion is dispositive, we have adopted a functional
    approach that looks to the effect of the motion, in order to
    determine whether it is properly characterized as dispositive or
    non-dispositive of a claim or defense of a party." (quoting Flam
    v. Flam, 
    788 F.3d 1043
    , 1046 (9th Cir. 2015)); Vogel v. U.S. Office
    Prods. Co., 
    258 F.3d 509
    , 514-15 (6th Cir. 2001) ("In determining
    - 17 -
    whether a particular motion is dispositive, this court undertakes
    functional    analysis        of    the     motion's     potential     effect    on
    litigation.       The   list       of    dispositive     motions     contained   in
    § 636(b)(1)(A) is nonexhaustive, and unlisted motions that are
    functionally equivalent to those listed in § 636(b)(1)(A) are also
    dispositive.").2
    Against         this        background,      we   conclude       that,
    notwithstanding       our    construction         of   "injunctive    relief"    in
    § 636(b)(1)(A), ML-CFC's motion is properly deemed "dispositive,"
    despite the District Court's apparent contrary determination.3 The
    2   A leading treatise provides:
    The rule's deviation from the language of the
    statute is not merely stylistic or a result of
    the distinct functions of the Act and the
    Federal Rules.    It is meant to reflect the
    legislative history of the 1976 amendments,
    the considerations underlying the differing
    standards of review, and the body of case law
    that   developed   in   practice   under   the
    provisions of Section 636(b)(1).
    12 Charles Alan Wright et al., Federal Practice and Procedure
    § 3068.2 (3d ed. 2019). Indeed, even before Rule 72 was issued,
    the Supreme Court understood § 636(b)(1) to differentiate between
    "dispositive" and "nondispositive" motions. See United States v.
    Raddatz, 
    447 U.S. 667
    , 673-74 (1980) (deeming the eight excepted
    motions in 
    28 U.S.C. § 636
    (b)(1)(A) "dispositive" and suggesting
    that a "pretrial matter" must be a "nondispositive motion[]").
    3 One might question how the text of 
    28 U.S.C. § 636
    (b)(1)(A)
    permits a motion not listed in § 636(b)(1)(A) that otherwise
    qualifies as a "pretrial matter" to nonetheless be subject to the
    standard of review for "dispositive" motions set forth in Rule
    72(b) rather than to the clearly erroneous/contrary to law standard
    of review set forth in Rule 72(a) and § 636(b)(1)(A), especially
    - 18 -
    motion to appoint a receiver seeks to have a court undertake an
    action that could have a significant impact on a party's ability
    to manage and control its property during the course of litigation.
    And thus, unsurprisingly, the law requires that a court, before it
    may take such an action, must consider an array of factors as a
    matter of equity, including the same critical merits-based factor
    that a court must consider before granting what is clearly, in
    this context, a "dispositive" motion -- a motion to issue a
    preliminary injunction.   That merits-based factor is a preliminary
    determination of which party is likely to succeed on the merits.
    See Consol. Rail Corp. v. Fore River Ry. Co., 
    861 F.2d 322
    , 326-27
    given the fact that Rule 72 postdates the enactment of § 636(b)(1).
    But, as we have noted, Phinney and PowerShare concluded that such
    treatment was proper for all analogous "dispositive" motions, as
    have other courts.     Moreover, the parties before us have not
    advanced any argument that those precedents were wrongly decided,
    nor have they argued that a motion to appoint a receiver is, by
    analogy to the conducting of voir dire in a felony trial, not a
    "pretrial matter" under § 636(b)(1)(A) even though it is made in
    advance of the trial. See Gomez v. United States, 
    490 U.S. 858
    ,
    874 n.28 (1989); United States v. Trice, 
    864 F.2d 1421
    , 1427-28
    (8th Cir. 1988). We thus follow the parties in proceeding on the
    assumption that whether the motion is "dispositive" within the
    meaning of Rule 72 is, well, dispositive of whether this motion is
    encompassed by the standard of review set forth in § 636(b)(1)(A)
    rather than § 636(b)(1)(B), even if it is not a type of motion
    expressly included in the list of motions excepted from
    § 636(b)(1)(A). Both parties' implicit acceptance of the premise
    that a motion that is "dispositive" under Rule 72 must also not be
    determinable by a magistrate judge without de novo review under
    § 636(b)(1)(B) strengthens our conclusion that it is appropriate
    for us to resolve the case on the basis that the motion at issue
    is "dispositive" even if the parties elected to focus their
    arguments elsewhere.

    (1st Cir. 1988) (listing factors to be considered "when determining
    the appropriateness of the appointment of a receiver," which
    includes, among others, "imminent danger that property will be
    lost or squandered, the inadequacy of available legal remedies,
    . . . the plaintiff's probable success in the action[,] and the
    possibility of irreparable injury to his interests in the property"
    (internal citations omitted)); 75 C.J.S. Receivers § 4 (2019).
    Of course, in this case, the Magistrate Judge purported
    to base the granting of the motion to appoint a receiver on the
    contract   between    the   parties   rather   than   on   an   equitable
    determination.   But, that fact makes the order here no less based
    on the merits of the underlying foreclosure action and thus no
    less "dispositive" in the relevant respect than a motion for a
    preliminary injunction.
    The Magistrate Judge granted the motion to appoint the
    receiver as a matter of contract only after determining, in accord
    with the contract, that there was an adequate showing that BPP had
    defaulted on the loan.      As that preliminary determination about
    whether there was such a default is central to the merits of the
    foreclosure action itself, the fact that the motion was granted on
    the basis of the contract fails to provide a basis for concluding
    that the motion was not, on this record, a "dispositive" one in
    the relevant sense.
    - 20 -
    Thus, because a motion for a preliminary injunction is
    a motion encompassed by the list of prohibited motions in 
    28 U.S.C. § 636
    (b)(1)(A), and because we must construe that list to "inform[]
    the       classification   of   other   motions     as    dispositive   or
    nondispositive," Phinney, 
    199 F.3d at 6
    , we conclude that this
    motion to appoint a receiver was "dispositive" under Rule 72.4
    And, in light of Phinney, PowerShare, and the related precedents
    from other courts, we thus do not reach the merits of whether the
    Magistrate Judge's decision was correct.          Rather, in harmony with
    Rule 72(b) and in accord with 
    28 U.S.C. § 636
    (b)(1), "we remand
    for the district court to apply de novo review to the magistrate
    judge's unauthorized order," after the parties have had a fresh
    chance to submit objections to that order.               United States v.
    Rivera-Guerrero, 
    377 F.3d 1064
    , 1071 (9th Cir. 2004).5
    4Motions to remand a case to state court are also generally
    not thought to be dispositive of a claim or defense, but that has
    not stopped other circuit courts from treating them as
    "dispositive" under Rule 72(b) in order to avoid constitutional
    questions. See First Union Mortg. Corp. v. Smith, 
    229 F.3d 992
    ,
    996 (10th Cir. 2000) ("Section 636 and Rule 72 must be read, where
    possible, so as to avoid constitutional problems, and '[t]he
    Constitution requires that Article III judges exercise final
    decisionmaking authority.'" (alteration in original) (quoting
    Ocelot Oil Corp. v. Sparrow Indus., 
    847 F.2d 1458
    , 1463 (10th Cir.
    1988))).
    5We note that although ML-CFC has argued throughout this
    litigation   that  the   motion   to  appoint   a  receiver   was
    "nondispositive" and therefore delegable as a "pretrial matter"
    under § 636(b)(1)(A), it has made no argument that, if the matter
    were "dispositive," then it was still proper for the Magistrate
    Judge to hear and determine the motion without de novo review
    - 21 -
    III.
    We vacate the District Court's decision overruling BPP's
    objections to the Magistrate Judge's order and remand for further
    proceedings consistent with this opinion.   No costs are awarded.
    rather than for the magistrate judge to merely issue a report and
    recommendation on the motion to be reviewed in accord with Rule
    72(b). And, of course, BPP is in no position to object to the
    approach we take here in light of its arguments in favor of
    treating this motion as one that may be given to a magistrate judge
    to issue a report and recommendation pursuant to 
    28 U.S.C. § 636
    (b)(1)(B).   See New Hampshire v. Maine, 
    532 U.S. 742
    , 750
    (2001) (noting that the doctrine of judicial estoppel may be used
    to "prohibit[] parties from deliberately changing positions
    according to the exigencies of the moment" (citing United States
    v. McCaskey, 
    9 F.3d 368
    , 378 (5th Cir. 1993)).
