    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF PUERTO RICO
    [Hon. Camille L. Vélez-Rivé, U.S. Magistrate Judge]
    Before
    Lynch, Thompson, and Kayatta,
    Circuit Judges.

    Associates, PSC was on brief, for appellee Julio Alicea-Vasallo.
    December 23, 2021
    LYNCH,    Circuit    Judge.       Certain    former     Automobile
    Accident Compensation Administration ("AACA") employees appeal the
    entry of summary judgment against their political discrimination
    claims, in favor of the AACA and its former Executive Director,
    Julio Alicea-Vasallo.     The employees were laid off pursuant to an
    agency-wide, facially neutral layoff plan (the "Layoff Plan")
    based on seniority.      They brought suit under 
    42 U.S.C. § 1983
    ,
    alleging violations of their federal First, Fifth, and Fourteenth
    Amendment   rights,    along    with   violations   of   Puerto     Rico   law.
    Holding it was bound by the Puerto Rico court decisions concluding
    that it was the Board of Directors -- not the Executive Director
    -- that was responsible for the Layoff Plan, the district court
    correctly adopted the Puerto Rico court decisions, then entered
    summary judgment for both AACA and Alicea-Vasallo.                Diaz-Baez v.
    Alicea Vasallo ("Diaz-Baez II"), No. 10-cv-1570, 
    2019 WL 8501708
    ,
    at *23–27 (D.P.R. Mar. 29, 2019).           Appellants concede that if the
    district court correctly adopted these issues decided by the Puerto
    Rico courts, the case must be resolved against them.               We affirm.
    I.
    A. Factual History
    The AACA is a public instrumentality of Puerto Rico,
    created pursuant to Law No. 138 of June 26, 1968, 
    P.R. Laws Ann. tit. 9, § 2051
     et seq.          Its purpose is to "administer[] Puerto
    Rico's unique system of compensating automobile accident victims,
    - 4 -
    irrespective     of    fault,   for    medical   expenses,    disability,
    dismemberment, death, and funeral expenses."         Bonilla v. Nazario,
    
    843 F.2d 34
    , 36 (1st Cir. 1988).         Appellants agree that the AACA
    has an identity distinct and separate from the Commonwealth of
    Puerto Rico and that it is a public entity that can "sue and be
    sued in its own name, [] can contract with others and except for
    its original funding, [] is [primarily] self-supporting . . . ."
    Oppenheimer Mendez v. Acevedo, 
    388 F. Supp. 326
    , 330 (D.P.R. 1974),
    aff'd, 
    512 F.2d 1373
     (1st Cir. 1975).1
    Between 2001 and 2008, the Popular Democratic Party
    ("PDP"), of which appellants assert they are members, was in power
    in Puerto Rico.       For decades, including that period, the AACA
    operated at a loss and had mounting financial deficits.             AACA's
    June 30, 2006 Financial Statement stated that the agency's "premium
    income" had been "insufficient to cover the operating expenses"
    for the "past several years."         This required the AACA frequently
    to withdraw from its investment portfolio "to cover operating
    funding needs."       A separate report prepared by the AACA's then-
    Director   of   Finance,   William    Jiménez,   covering   the   2005-2006
    fiscal year contained an acknowledgment by the AACA's Board of
    Directors that the agency had accrued a cumulative deficit totaling
    more than $99 million between the fiscal years 1998-1999 and 2004-
    1    In Spanish, the agency's name is the Administración de
    Compensaciones por Accidentes de Automóviles ("ACAA").
    - 5 -
    2005.     This report also showed that the agency was operating at
    about an $8.0 million deficit for the 2005-2006 fiscal year.
    In 2007, the Board considered measures to reduce both
    its costs and its operational deficit.                Jiménez recommended to the
    Board that the AACA reduce its workforce by more than 100 employees
    and close four offices and two Departments, among other measures.
    Jiménez proposed that additional personnel cuts be made during the
    2007-2008 fiscal year to reduce the operational deficit.
    The Board declined to adopt any of these measures to
    address    the     deficit.      Instead,       the    Board   approved    several
    amendments to its Personnel Regulations, purporting to provide
    additional protection for the AACA's managerial employees against
    layoff.    One such amendment required the AACA to consider employee
    performance as a criterion when determining priority for layoff.
    In November 2008, the New Progressive Party ("NPP") came
    into    power     in   Puerto   Rico.       This      constituted   a    change    in
    administration from the PDP.            The newly-elected Governor of Puerto
    Rico    issued    Executive     Order    OE-2009-001      on   January    8,   2009,
    decreeing    an    economic     and   fiscal    state     of   emergency    in    the
    Commonwealth and ordering the elimination of nearly one third of
    politically appointed positions.             The legislature of Puerto Rico
    enacted Act No. 7-2009 ("Law 7") in March 2009, 
    P.R. Laws Ann. tit. 3, § 8791
     et seq., establishing seniority as the primary
    criterion used to implement this layoff plan, 
    id.
     § 8799(b)(3).
    - 6 -
    Although the AACA was not covered by Law 7, the Board of
    Directors simultaneously was evaluating the agency's fiscal state
    and considering a similar plan.     The Board discussed the Executive
    Order at a January 16, 2009 Board meeting.      At that Board meeting,
    AACA's Deputy Director of Finance, Rebecca Cotto, also reported
    that the AACA was operating at a $15 million deficit and was asked
    about the measures the AACA was taking to remedy this.             Similar
    discussions continued through May 2009, when NPP member Alicea-
    Vasallo was appointed Executive Director of the AACA.             The AACA
    continued operating at a deficit at that time, including a loss in
    the category of insurance operations in the amount of more than
    $63 million.
    The AACA Board of Directors held another meeting to
    discuss this fiscal state on October 15, 2009, at which the Board
    discussed with Alicea-Vasallo the creation of the Layoff Plan.
    During   that   meeting,   the   Board's   president   inquired    of   the
    Executive Director concerning a layoff plan that would save the
    AACA between $4.5 and $5 million.          In response, Alicea-Vasallo
    explained that the way to accomplish that degree of reduction, the
    plan would be to lay off employees based on seniority (as did Law
    7), covering a period from July 1, 2000 through June 30, 2009.
    That is, employees with less than nine years of public service as
    of June 30, 2009 (the "cut-off date") would be subject to the Plan.
    Alicea-Vasallo represented that this would affect fewer managerial
    - 7 -
    employees than the layoff plan recommended by Jiménez in 2007.
    Plaintiffs allege that, because of the cut-off date, the plan
    targeted   employees     who   had     been     hired     during     the   PDP
    administration.    The Board also passed Resolution No. 2009 Oct-
    17A that day, amending the Personnel Regulations to eliminate the
    consideration of employee performance -- a subjective criterion
    -- for layoffs and to place seniority as the primary criterion.
    Within two weeks, the Board also approved the Layoff
    Plan recommended by the Executive Director via Resolution No. 2009
    OCT 21A, which would lay off all managerial employees with less
    than nine years of public service by the June 30, 2009 cut-off
    date.   The resolution stated, specifically, that:
    Be it hereby Resolved by the Board of
    Directors   of   the    Automobile   Accident
    Compensation Administration to approve the
    implementation of the Lay Off Decree Plan in
    all aspects because they are found to be
    adequate and serve the purposes of improving
    the grave fiscal situation of the agency and
    also to safeguard the rights of employees who
    render services at [AACA].
    Alicea-Vasallo gave notice of the Layoff Plan adopted by
    the Board to all relevant employees between November 10, 2009 and
    January 7, 2010 in accordance with the Plan.            This notice informed
    the   employees   of   their   right   to     request    both   an   informal
    administrative hearing within five days of the notification and a
    review of their dismissal before an administrative judge within
    thirty days, citing Article 18 of the Personnel Regulations.
    - 8 -
    Article 18.3 of the Regulations further authorizes employees to
    file a petition for review of the administrative judge's decision
    with the Puerto Rico Circuit Court of Appeals.                    All of the
    plaintiffs in this case had less than nine years in public service
    by the selected cut-off date, although not necessarily by the date
    their layoffs became effective.          The layoffs became effective on
    March 19, 2010.
    The AACA's June 30, 2011 Financial Statement showed that
    these cost reduction measures had in fact reduced both the amount
    of the annual losses and the agency's net deficit.            The statement
    showed a loss in 2011 in the category of insurance operations in
    the amount of approximately $1 million, i.e., a more than ninety
    percent reduction in losses compared to the previous year.               The
    statement further reported a decrease in the agency's net deficit
    by $20 million, and, between 2010 and 2011, "no withdrawals were
    made   from        the   investment   portfolio   to    finance    operating
    activities."
    B. Procedural History
    The Layoff Plan has led to multiple administrative and
    judicial proceedings which we briefly describe.
    i.     The Instant Case
    It is uncontested that the dismissed AACA employees were
    deemed career employees in public service with protected property
    interests in their continued employment.               Rodriguez-Sanchez v.
    - 9 -
    Mun. of Santa Isabel, 
    658 F.3d 125
    , 129 (1st Cir. 2011).           On June
    22, 2010, sixty-two such former employees filed this § 1983 action,
    claiming that they were dismissed illegally from their respective
    positions following the election of the NPP in 2008 due to their
    affiliation with the PDP.         Plaintiffs charge defendants with
    "conspir[ing]   in   order   to   design   and   implement   a   scheme   to
    wrongfully dismiss plaintiffs due exclusively to their political
    affiliation," in violation of the AACA's Personnel Regulations and
    federal and Puerto Rico law.         They allege that Alicea-Vasallo
    intentionally set the seniority requirement for the Layoff Plan at
    nine years through only June 30, 2009 -- rather than plaintiffs'
    formal date of layoff -- to target employees hired while the PDP
    was in power.   Plaintiffs seek reinstatement and damages.2
    2    After the district court largely denied defendants'
    motion to dismiss the complaint in March 2011, the plaintiffs filed
    two amended complaints to name additional former AACA employees as
    co-plaintiffs, and the parties consented to proceed before a
    magistrate judge.    Since then, plaintiffs Juana M. Contreras-
    Castro, Leila A. Hernández-Jiménez, Yelitza I. Hernández-
    Hernández, Yalitza Rosario-Menéndez, Raquel Cardona-Soto, Maribel
    Alicea-Lugo, Humberto L. Muler-Santiago, Mariela Torres-Molini,
    Carmen Yolanda Vázquez-Ortiz, Luis A. Rodríguez-Toro, Nereida
    Rivera-Batista, Bernice Berberena-Maldonado, Ricardo Rosario-
    Sanchez, Axel Fresse-Álvarez, Gloriely Miranda-Ocasio, Luis A.
    Muler-Santiago, Gretchen M. Acevedo-Rivera, Domingo Mariani-
    Molini, Rebeca M. Negrón-Umpierre, Jorge Aparicio-Torres, Carmen
    E. Rodríguez-Santiago, Lynette Yambó-Mercado, Marianna Ramirez-
    Álvarez, Conjugal Partnership Fresse-Miranda, and Conjugal
    Partnership Rosario-Berberena have voluntarily dismissed their
    claims and thus are not participating in this appeal. Further,
    the only defendants participating in the appeal are the AACA and
    Alicea-Vasallo.
    - 10 -
    On May 2, 2012, plaintiffs moved for "partial" summary
    judgment, requesting that the district court declare the Layoff
    Plan discriminatory in purpose and implementation.                        The court
    denied the motion, holding that plaintiffs "failed to adduce
    evidence showing that defendants had knowledge of the identities
    or political affiliations of the [plaintiff] workers in each
    position"      and    that    the   political    discrimination      claims    were
    "speculative         and   unsupported."        Diaz-Baez    v.   Alicea    Vasallo
    ("Diaz-Baez I"), No. 10-cv-1570, 
    2012 WL 5566444
    , at *4 (D.P.R.
    Nov. 15, 2012).
    After the close of discovery, both parties filed summary
    judgment motions.          Diaz-Baez II, 
    2019 WL 8501708
    , at *9.           In August
    2015,    the    district      court   entered     a   stay   based   on    Railroad
    Commission of Texas v. Pullman Co., 
    312 U.S. 496
     (1941), because
    the Puerto Rico Supreme Court was considering the validity of
    several dismissals under the Layoff Plan in Rodríguez-Ocasio v.
    ACAA, 
    197 P.R. Dec. 852
    , 
    2017 WL 1449701
     (P.R. 2017).                The federal
    proceedings were stayed "until such time as the Puerto Rico Supreme
    Court resolves the pending issues before it."3
    3    Plaintiffs had appealed the stay and, on appeal, we
    questioned the parties as to whether the automatic stay under the
    Puerto Rico Oversight, Management, and Economic Stability Act, 
    48 U.S.C. § 2161
     et seq. ("PROMESA"), applied to this case.        We
    dismissed the appeal as moot before deciding the issue. It remains
    unclear whether the PROMESA stay applies, but we need not reach
    the question because it is not an issue of Article III
    jurisdiction. See Moriarty v. Colvin, 
    806 F.3d 664
    , 668 (1st Cir.
    - 11 -
    The Supreme Court promulgated its opinion in Rodríguez
    Ocasio in April 2017, "reinstat[ing] the rulings issued by the
    Administrative Judge of the [AACA]" which upheld the dismissals
    pursuant to the Plan.        197 P.R. Dec. at 857.        Thereafter, the
    district   court    denied   without   prejudice   the   parties'   pending
    summary judgment motions.          Amended summary judgment proceedings
    ensued, and concluded with the district court granting defendants'
    motions and denying plaintiffs' as moot.           Diaz-Baez II, 
    2019 WL 8501708
    , at *35.
    As we consider the preclusive effect of the Puerto Rico
    courts' decisions dispositive as to the pending appeal, we do not
    further describe the proceedings before the district court.             We
    instead turn to the relevant Puerto Rico court proceedings.
    ii.     Related Cases
    Several judicial and administrative challenges to the
    Layoff Plan also took place during the relevant time period.            We
    summarize only those cases necessary to our issue preclusion
    analysis, starting with Humberto Muler v. ACAA, No. 2010-va-43,
    KLRA 201001000, 
    2010 WL 5877970
     (P.R. Cir. Nov. 24, 2010).
    2015) (bypassing the statutory jurisdictional question because
    "resolving this case on the merits by affirming the grant of
    summary judgment has the same consequences as concluding that we
    do not have jurisdiction" (citing Parella v. Ret. Bd. of R.I.
    Emps.' Ret. Sys., 
    173 F.3d 46
    , 54 (1st Cir. 1999))); Royal Siam
    Corp. v. Chertoff, 
    484 F.3d 139
    , 143–44 (1st Cir. 2007) (similar).
    - 12 -
    After the layoffs became final, the dismissed employees
    filed a formal administrative appeal before the AACA's Office of
    Hearing Examiner (also titled the "Administrative Judge").            As
    those proceedings were pending, the Puerto Rico Supreme Court
    issued an opinion in Molini Gronau v. Corporación de Puerto Rico
    para la Difusión Pública, 
    179 P.R. Dec. 674
     (P.R. 2010), in which
    the court held that an administrative judge lacked jurisdiction to
    review the validity of a severance plan recommended by another
    corporation's executive director and approved by its board of
    directors.    The Supreme Court explained that the Court of First
    Instance had exclusive jurisdiction over that board's actions.
    Thereafter,    twenty-seven   of   the   current   plaintiffs
    questioned whether the Administrative Judge had jurisdiction to
    consider the merits of the Layoff Plan in this case.            Humberto
    Muler, 
    2010 WL 5877970
    , at *1.     These plaintiffs argued by analogy
    that the Administrative Judge lacked jurisdiction because, as in
    Molini Gronau and contrary to their current position, it was the
    Board of Directors -- not the Executive Director -- which approved
    the Plan.     
    Id. at *5
    .     The Administrative Judge rejected this
    argument, ruling that it retained jurisdiction over the challenges
    to the Layoff Plan because it was the Executive Director who made
    the final layoff decision.      
    Id. at *6
    .     The twenty-seven former
    employees appealed that ruling to the Commonwealth's Circuit Court
    of Appeals.
    - 13 -
    The appellate court framed the question on appeal as:
    "whether the layoffs announced in the [AACA] as a result of the
    implementation of the Layoff Plan [a]pproved by the Board of
    Directors were determined by the corporation's Executive Director
    or by the Board of Directors."    
    Id. at *11
    .   The court concluded
    that the ultimate responsibility for the Layoff Plan belonged to
    the Board of Directors and not the Executive Director.           
    Id. at *15
    .   Accordingly, it reversed the Administrative Judge's exercise
    of jurisdiction over the Layoff Plan's validity and instructed the
    agency that it could review only the calculation of seniority as
    to the employees.   
    Id.
     at *13–15.     That decision was not appealed,
    rendering it final.
    The   employees'   claims    were   remanded   back   to   the
    Administrative Judge for the agency to evaluate the seniority
    calculations.    The Administrative Judge ruled that all of the
    employees laid off had less than nine years of public service by
    the cut-off date, and confirmed the layoffs. Ignoring the decision
    in Humberto Muler just described, the Administrative Judge also
    reviewed the legality of the Plan's cut-off date in the various
    individual's cases on appeal.     Analogizing to Law 7 of March 9,
    2009, 
    P.R. Laws Ann. tit. 3, § 8791
     et seq., which was upheld by
    the Puerto Rico Supreme Court in Sánchez Collazo v. Departmento de
    la Vivienda, 
    184 P.R. Dec. 95
     (P.R. 2011), the Administrative Judge
    held that the Plan's use of a cut-off date was valid.             Twelve
    - 14 -
    former employees appealed this ruling on the ground that it was
    error for the Administrative Judge to rely on Law 7 and Sánchez
    Collazo.
    The    Puerto    Rico    Circuit     Court    of   Appeals     rendered
    inconsistent     decisions   on     appeal.      Eight    cases   affirmed      the
    administrative     decision,       whereas    four   reversed     based    on   the
    Administrative Judge's reliance on Law 7.            Without questioning the
    Administrative Judge's jurisdiction to consider the validity of
    the Layoff Plan, the courts reversing the decision held that Law
    7 did not apply to the AACA and the uniform cut-off date utilized
    in the Layoff Plan was invalid.              The AACA petitioned the Puerto
    Rico Supreme Court for review of those rulings.
    The Supreme Court granted certiorari in three of the
    reversals and consolidated the appeals in Rodríguez-Ocasio v.
    AACA, 
    197 P.R. Dec. 852
     (P.R. 2011).             The Supreme Court reversed
    the Circuit Court of Appeals, holding that the decision in Humberto
    Muler that administrative judges lacked jurisdiction to consider
    the validity of the Layoff Plan constituted "the law of the case."
    Rodríguez-Ocasio,     197    P.R.      Dec.    at    863–66.       Because      the
    Administrative Judge lacked such jurisdiction, it was error for
    the Circuit Court of Appeals to review the agency's conclusion as
    to the validity of the Layoff Plan.            Id. at 867–68.

    II.
    Plaintiffs'     primary    appellate      argument    is    that   the
    district court erred by concluding that plaintiffs were either
    precluded or estopped from arguing that it was the Executive
    Director, not the Board of Directors, who was responsible for the
    Layoff Plan.    At oral argument, plaintiffs' counsel conceded that
    this appeal turns entirely on the answer to this question of who
    made the adverse employment decision.           Counsel stated that if we
    find, as we do, that the Board made the decision, there is nothing
    left of the lawsuit.
    Orders granting summary judgment are reviewed de novo,

    court's res judicata determination is likewise reviewed de novo.

    Synopsys, Inc., 
    374 F.3d 23
    , 30 (1st Cir. 2004).
    A.   Issue Preclusion
    The district court was correct to conclude the twenty-
    seven   plaintiffs   who   were     also   party   to   Humberto      Muler   are
    - 16 -
    precluded from relitigating the fact that it was AACA's Board of
    Directors who approved the Layoff Plan.      See Diaz-Baez II, 
    2019 WL 8501708
    , at *23-24.     Puerto Rico's Civil Code provides that,
    [i]n order that the presumption of res
    adjudicata may be valid in another suit, it is
    necessary that, between the case decided by
    the sentence and that in which the same is
    invoked, there be the most perfect identity
    between the things, causes, and persons of the
    litigants, and their capacity as such.
    
    P.R. Laws Ann. tit. 31, § 3343
    .     The statute covers both claim and
    issue preclusion.      Baez-Cruz v. Municipality of Comeiro, 
    140 F.3d 24
    , 29 (1st Cir. 1998).
    Despite "the rather strict wording of Puerto Rico's
    mutuality requirement," the inclusion of new parties in a case "is
    not a bar to the application of [issue preclusion]."              Sánchez-
    Núñez v. P.R. Elec. Power Auth., 
    509 F. Supp. 2d 137
    , 146 (D.P.R.
    2007) (citing Baez-Cruz, 
    140 F.3d at 29
    ).      Nor is perfect identity
    of causes required "when the defense is one of issue preclusion,
    rather than claim preclusion."      Baez-Cruz, 
    140 F.3d at
    30 (citing
    A & P Gen. Contractors v. Asociación Caná Inc., 
    10 P.R. Offic. Trans. 984
    ,    996   (P.R.   1981)).     Instead,   issue     preclusion
    "forecloses relitigation in a[ny] subsequent action of a fact
    essential for rendering a judgment in a prior action between
    [primarily] the same parties, even when different causes of action
    are involved."     Cruz Berríos v. Gonzalez-Rosario, 
    630 F.3d 7
    , 12
    (1st Cir. 2010) (quotations and citation omitted).            Courts apply
    - 17 -
    this doctrine to reduce litigation expenses, conserve judicial
    resources,     and    cultivate     reliance    on    judicial     decisions    by
    avoiding inconsistent conclusions.             
    Id. at 11
    .
    The twenty-seven plaintiffs who were party to Humberto
    Muler are precluded from questioning, for at least the second time,
    who is responsible for the Layoff Plan.                A material question in
    both cases has been whether the Board of Directors or the Executive
    Director was responsible for the Plan.            Compare Diaz-Baez II, 
    2019 WL 8501708
    , at *23, with Humberto Muler, 
    2010 WL 5877970
    , at *11.
    The plaintiffs were given a full and fair opportunity to litigate
    the question of who approved the Plan in Humberto Muler, and the
    Circuit Court of Appeals rendered a final judgment concluding that
    it was the Board of Directors.           
    2010 WL 5877970
    , at *15 ("[I]n
    this case it was the Board of Directors which made the decision to
    layoff   (1)   the    management     employees,       (2)   and   establish    the
    benchmark of having been employed 9 years or less . . . ."); see
    also Kremer v. Chem. Const. Corp., 
    456 U.S. 461
    , 481 (1982)
    (holding that "full and fair opportunity to litigate" is satisfied
    by minimum procedural requirements of the Fourteenth Amendment).
    Plaintiffs -- who failed to appeal the Humberto Muler decision --
    are   barred   from    taking   a   second     bite   of    the   apple   in   this
    litigation.      See also Rodríguez Ocasio, 197 P.R. Dec. at 853
    (holding that Humberto Muler constitutes "law of the case" as to
    - 18 -
    the issue of jurisdiction, which depends on who approved the Layoff
    Plan).
    Plaintiffs' arguments to the contrary lack merit.             The
    arguments   misconstrue       the   doctrine   of   issue   preclusion   under
    Puerto Rico law, which requires neither strict identity of parties
    nor causes of action.          See Baez-Cruz, 
    140 F.3d at 29
     (reading
    § 3343   "as     permitting   issue    preclusion    to   operate   against   a
    plaintiff who[, as here,] adds defendants in the second action.");
    id. at 30 ("The Supreme Court of Puerto Rico has [] stated that
    identity of causes is unnecessary when the defense is one of issue
    preclusion, rather than claim preclusion.").
    B.     Judicial Estoppel
    The district court also held that the remaining sixteen
    plaintiffs were judicially estopped from relitigating the question
    of who approved the Layoff Plan.         In 2010, these plaintiffs, among
    others, moved to intervene in another case filed in the Court of
    First Instance challenging the Layoff Plan, María Díaz-Báez v.
    ACAA, No. K PE2009-4889.            In this motion, the former employees
    stated that:
    [w]e observe that the Regulation does not
    confer power on the Examining Officer to
    review the decisions of the Board of
    Directors. In this case, the approval of the
    Cessation Plan becomes a product of the Board
    of Directors that is neither subject to
    revision by the Examining Officer nor by the
    Executive Director.   This intricate process
    - 19 -
    renders the notification        of   a   hearing   as
    completely defective.
    Their motion was allowed. The plaintiffs having successfully taken
    the position previously that it was the Board of Directors who
    approved   the   Layoff   Plan,   the   district    court   estopped   these
    plaintiffs from taking the opposite position in this litigation,
    citing Alternative System Concepts Inc., 
    374 F.3d at 32-33
     ("[T]he
    doctrine of judicial estoppel prevents a litigant from pressing a
    claim that is inconsistent with a position taken by that litigant
    . . . in a prior legal proceeding . . . .").
    The federal doctrine of judicial estoppel "prevents a
    litigant from pressing a claim that is inconsistent with a position
    taken by that litigant either in a prior legal proceeding or in an
    earlier phase of the same legal proceeding."           Bossé v. N.Y. Life
    Ins. Co., 
    992 F.3d 20
    , 32 (1st Cir. 2021) (quoting InterGen N.V.
    v. Grina, 
    344 F.3d 134
    , 144 (1st Cir. 2003)).          It "is designed to
    ensure that parties proceed in a fair and aboveboard manner,
    without making improper use of the court system."             
    Id.
     (quoting
    InterGen N.V., 
    344 F.3d at 144
    ).
    In general, three conditions must be satisfied for the
    doctrine of judicial estoppel to apply: "First, the estopping
    position and the estopped position must be directly inconsistent,"
    Alt. Sys., 
    374 F.3d at 33
    , "[s]econd, the responsible party must
    have succeeded in persuading a court to accept its prior position,"
    - 20 -
    
    id.,
     and "[t]hird, the party seeking to assert the inconsistent
    position must stand to derive an unfair advantage if the new
    position is accepted by the court," Knowlton v. Shaw, 
    704 F.3d 1
    ,
    10 (1st Cir. 2013) (citation omitted).
    These plaintiffs' appellate brief does not even attempt
    to challenge the district court's application of the necessary
    conditions.4   They have made no developed or cognizable argument
    that there was an abuse of discretion by the district court in its
    judicial estoppel finding.5   These plaintiffs waived the argument
    that judicial estoppel does not apply by failing to develop it.
    See United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990)
    ("[I]ssues adverted to in a perfunctory manner, unaccompanied by
    some effort at developed argumentation, are deemed waived.").
    III.
    Because appellants concede that this appeal turns on
    whether the district court correctly concluded that they are barred
    from arguing in this litigation that the Executive Director, and
    4    We need not decide whether federal law or Puerto Rico
    law governs the application of judicial estoppel because the
    plaintiffs do not address the question and fail to develop any
    argument under either jurisdiction's law. See Thorne v. Howe, 
    466 F.3d 173
    , 181 n.1 (1st Cir. 2006). The text above articulates the
    familiar federal standard.
    5    These plaintiffs at most cite one inapposite case in a
    footnote, see A & P Gen. Contractors, 
    10 P.R. Offic. Trans. 984
    (analyzing the doctrine of res judicata, but not judicial
    estoppel), and argue that judicial estoppel requires strict
    mutuality of parties.
