    LIPEZ, Circuit Judge.    In the legislation addressing the
    Commonwealth of Puerto Rico's fiscal crisis, Congress gave the
    Financial Oversight and Management Board for Puerto Rico ("the
    Oversight Board" or "the Board") authority to object to, and block
    the implementation of, local laws that are inconsistent with
    efforts to return the Commonwealth to fiscal solvency. Appellants,
    the Governor of Puerto Rico and the Puerto Rico Fiscal Agency and
    Financial Advisory Authority (known as "AAFAF" based on its Spanish
    acronym), contend that the district court erred when it rejected
    their contention that the Oversight Board acted arbitrarily and
    capriciously in objecting to four laws duly enacted by Puerto
    Rico's legislature.     We disagree and therefore affirm.
    I.
    A.   Legal Background
    In 2016, Congress passed the Puerto Rico Oversight,
    Management, and Economic Stability Act ("PROMESA") to address the
    Commonwealth's fiscal crisis, facilitate restructuring of its
    public debt, ensure its future access to capital markets, and
    provide for its long-term economic stability.1        See 48 U.S.C.
    1 We have elsewhere provided a more comprehensive background
    on Puerto Rico's fiscal crisis and the enactment of PROMESA,
    including PROMESA's creation of a process for the Commonwealth to
    undergo bankruptcy proceedings. See, e.g., Aurelius Inv., LLC v.
    Puerto Rico, 
    915 F.3d 838
    , 843-46 (1st Cir. 2019) (overruled on
    other grounds by Fin. Oversight & Mgmt. Bd. for P.R. v. Aurelius
    Inv., LLC (In re Fin. Oversight & Mgmt. Bd. for P.R.), 140 S. Ct.
    - 3 -
    § 2194(m)-(n).       PROMESA established the Oversight Board, whose
    members    are     appointed     by   the    President,   with    wide-ranging
    authority to oversee and direct many aspects of Puerto Rico's
    financial recovery efforts.           See, e.g., id. §§ 2141-2147.        Among
    its responsibilities is the certification of a fiscal plan and
    annual    budget    for    the   Commonwealth.      Id.   §§ 2141-2142.      Of
    relevance to this appeal, PROMESA also provides the Oversight Board
    with the authority to review and ask the district court to enjoin
    the implementation of duly enacted Commonwealth legislation when
    the Oversight Board determines that the legislation does not comply
    with the approved fiscal plan or with PROMESA's statutory scheme
    to return Puerto Rico to fiscal solvency.2
    Section       108(a)(2)   of     PROMESA,   titled   "Autonomy   of
    Oversight Board," provides that "[n]either the Governor nor the
    Legislature [of the Commonwealth] may . . . enact, implement, or
    enforce any statute, resolution, policy, or rule that would impair
    or defeat the purposes [of PROMESA], as determined by the Oversight
    Board."    
    48 U.S.C. § 2128
    (a).             To that end, PROMESA outlines a
    multi-step, back-and-forth process by which the Oversight Board
    1649 (2020)); Union De Trabajadores De La Industria Eléctrica Y
    Riego v. FOMB (In re FOMB), 
    7 F.4th 31
    , 35 (1st Cir. 2021).
    2 During the period relevant to this appeal, Puerto Rico was
    operating under an approved "2019 Fiscal Plan" covering a five-
    year period. The 2019 plan was subsequently replaced by a 2020
    Fiscal Plan, covering the period through Fiscal Year 2025, which
    was certified by the Oversight Board in May 2020.
    - 4 -
    reviews    Commonwealth      legislation   for    consistency    with    the
    statute's goals.
    Section 204(a) provides that "not later than 7 business
    days after [the Commonwealth] duly enacts any law during any fiscal
    year in which the Oversight Board is in operation, the Governor
    shall submit the law to the Oversight Board" along with (1) "[a]
    formal    estimate    prepared   by   an   appropriate     entity   of   the
    territorial government with expertise in budgets and financial
    management of the impact, if any, that the law will have on
    expenditures and revenues"; and (2) a "certification of compliance
    or noncompliance" by that entity stating whether the law is
    "significantly inconsistent with the Fiscal Plan for the fiscal
    year".    
    Id.
     § 2144(a)(1)-(2).       The Oversight Board then notifies
    the Governor and the Legislature if a submission is problematic,
    either because it lacks a formal estimate or certification, or
    because the certification states that the law is significantly
    inconsistent   with    the   fiscal   plan.      Id.   § 2144(a)(3).     The
    Oversight Board may direct the Commonwealth to provide the missing
    estimate or certification, or, if the Commonwealth has certified
    that the law is inconsistent with the fiscal plan, may direct the
    Commonwealth to "correct the law to eliminate the inconsistency"
    or "provide an explanation for the inconsistency that the Oversight
    Board finds reasonable and appropriate."         Id. § 2144(a)(4)(B).     If
    the Commonwealth "fails to comply with a direction given by the
    - 5 -
    Oversight Board," the Board "may take such actions as it considers
    necessary, consistent with [PROMESA], to ensure that the enactment
    or enforcement of the law will not adversely affect the territorial
    government's compliance with the Fiscal Plan, including preventing
    the enforcement or application of the law."    Id. § 2144(a)(5).3
    In addition to this general review process for duly
    enacted legislation, PROMESA also gives the Oversight Board the
    authority to review any request by the Governor to the Legislature
    "for the reprogramming of any amounts provided in a certified
    Budget."   Id. § 2144(c)(1).     The Governor must submit any such
    request to reallocate budgeted funds to the Oversight Board.    Id.
    The Board then reviews whether such request "is significantly
    inconsistent with the Budget."    Id.   The reprogramming cannot be
    adopted "until the Oversight Board has provided the Legislature
    with an analysis that certifies such reprogramming will not be
    inconsistent with the Fiscal Plan and Budget."    Id. § 2144(c)(2).
    Last, but certainly not least, PROMESA authorizes the
    Board to "seek judicial enforcement of its authority to carry out
    its responsibilities."   Id. § 2124(k).
    3 The Legislature may request that the Oversight Board
    "conduct a preliminary review of proposed legislation" before
    enactment, but "any such preliminary review shall not be binding
    on the Oversight Board in reviewing any law subsequently
    submitted." 
    48 U.S.C. § 2144
    (a)(6).

    Although several of the provisions governing the Board's
    ability to review Commonwealth laws have not previously come before
    this court, the district court has authored several decisions that
    lay the groundwork for this appeal.4           In its Law 29 I decision,
    the   court    rejected     the    Commonwealth's     argument   that    its
    "certification of lack of inconsistency [between a law and the
    fiscal plan] insulates a newly enacted law from scrutiny or
    challenge by the Oversight Board."          In re Fin. Oversight Mgmt. Bd.
    for P.R., 
    403 F. Supp. 3d 1
    , 12 (D.P.R. 2019) ("Law 29 I").               To
    the   contrary,   the     court   concluded,    a   certification   by   the
    Commonwealth is not "preclusive of inquiries [by the Board] as to
    its sufficiency or accuracy," and PROMESA "demands recognition of
    the Oversight Board's ability to question and, if necessary, bring
    before the [c]ourt challenges to the sufficiency and accuracy of
    documents as important as revenue estimates and certifications
    regarding significant inconsistencies with fiscal plans."            Id. at
    13-14.    The court further explained that a "formal estimate" under
    section 204(a) means a complete and accurate estimate "covering
    revenue and expenditure effects of new legislation" over the entire
    period of the fiscal plan.        Id. at 13.   Simply submitting a dollar
    4Pursuant to 
    48 U.S.C. § 2168
    , the Chief Justice of the
    United States has designated Judge Swain to preside over certain
    cases involving PROMESA's implementation, and the relevant
    district court decisions were authored by Judge Swain.
    - 7 -
    estimate "on official agency letterhead, no matter how conclusory
    or incomplete," does not suffice.       Id. at 12.
    In its subsequent Law 29 II decision, the court held
    that Board determinations that Commonwealth laws impair or defeat
    the purposes of PROMESA are reviewed under the "arbitrary and
    capricious"   standard   typically   used   to    review   federal   agency
    decisions.    In re Fin. Oversight & Mgmt. Bd. for P.R., 
    616 B.R. 238
    , 252-53 (D.P.R. 2020) ("Law 29 II").         While acknowledging that
    PROMESA specifically provides that the Oversight Board "shall not
    be considered to be . . . [an] agency . . . of the Federal
    Government," 
    48 U.S.C. § 2121
    (c)(2), the court noted that the
    Board's "powers and functions are similar to those of agencies
    charged by Congress with carrying out the provisions of statutes,"
    Law 29 II, 616 B.R. at 252.    Under the "arbitrary and capricious"
    standard of review, the court "must decide whether the Oversight
    Board's determinations were supported by a rational basis and must
    affirm [its] decisions if they are 'reasoned[] and supported by
    substantial evidence in the record.'"       Law 29 II, 616 B.R. at 253
    (quoting Trafalgar Cap. Assocs., Inc. v. Cuomo, 
    159 F.3d 21
    , 26
    (1st Cir. 1998)).   Thus, the court held that the Oversight Board's
    determinations will only be set aside if they are "arbitrary,
    capricious, or manifestly contrary to the statute."            Id. at 254
    (quoting Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc.,
    
    467 U.S. 837
    , 844 (1984)).
    - 8 -
    In Law 29 II, the district court also noted that PROMESA
    "allows    the   Oversight   Board    to     prevent   the    application     or
    enforcement of a law when the Commonwealth government fails to
    comply with a direction given by the Oversight Board pursuant to
    section 204(a)[]."    Id. at 248.      And the Board "is not required to
    prove to the [c]ourt that [a law] is significantly inconsistent
    with the fiscal plan" to demonstrate the Commonwealth's failure to
    comply with its obligations under section 204.               Id.
    The Commonwealth did not appeal either of the Law 29
    decisions.
    B.   Factual Background
    This appeal involves four Commonwealth laws that were
    passed by the Legislature and challenged by the Board.5               Below, we
    describe     these   laws    and     the     communications        between   the
    Commonwealth and the Board, pursuant to section 204(a), following
    their enactment.6
    5 A fifth law was before the district court but is not part
    of the present appeal.
    6 Pursuant to Executive Order 2019-057, the Puerto Rico
    Department of Treasury ("Treasury"), AAFAF, and the Puerto Rico
    Office of Management and Budget ("OMB") work together to prepare
    fiscal impact estimates and certifications for any enacted laws.
    For simplicity, we refer to the Governor, AAFAF, OMB, and Treasury
    collectively as "the Commonwealth."
    - 9 -
    1.   Act 82 and Act 138
    Because         the    communications           regarding           these       two
    healthcare-related          laws    were     intertwined,           we     discuss         them
    together.    Act 82, signed into law on July 30, 2019, creates a new
    regulatory scheme and establishes an "Office of the Regulatory
    Commissioner of Pharmacy Services and Benefit Managers" within the
    Puerto Rico Department of Health to regulate Pharmacy Benefit
    Managers ("PBMs") and Pharmacy Benefit Administrators ("PBAs"),
    entities that negotiate medication costs between pharmaceutical
    companies and third-party payers, including the Commonwealth.                                As
    the district court explained, "Act 82 changes the arrangements
    between [these entities] and pharmacies to require that pharmacies
    be     reimbursed    for     at    least     their     cost        of    acquisition         of
    medications."        The     Commonwealth      asserts        that       this    change      is
    necessary    to     allow    pharmacies       to   recover         their    actual         drug
    acquisition       costs,     ensuring       that     they     continue          to   acquire
    necessary medications for the people of Puerto Rico.
    Act 138, signed into law on August 1, 2019, amends the
    Insurance Code of Puerto Rico to (1) prohibit health care insurers
    from     denying    provider       enrollment        applications          submitted         by
    qualified    health    care       professionals       in     Puerto       Rico,      and    (2)
    prohibit Managed Care Organizations from unilaterally terminating
    or     rescinding    contracts       with     health        care    providers.              The
    Commonwealth asserts that the law was enacted "to discourage the
    - 10 -
    mass exodus of health professionals [from Puerto Rico] and increase
    the availability of health care services throughout the Island."
    The Commonwealth did not submit any section 204(a)-
    required materials on Act 82 within the statutory seven-day period.
    On September 12, 2019, more than a month after Act 138 was signed
    into law, the Commonwealth submitted to the Board a copy of the
    Act with a certificate reading as follows:
    Legislative Measure Number:
    •    Act No. 138-2019 ("Act 138"), herein attached.
    Estimate of Impact of the Legislative Measure on Expenditures
    and Revenues:
    •    Act 138 has no impact on expenditures or revenues.
    Determination of the Legislative Measure's Compliance with the
    Fiscal Plan:
    •    Act 138 is not significantly inconsistent with the New Fiscal
    Plan for Puerto Rico.
    On   November   15,    2019,   the   Board   notified   the
    Commonwealth by letter of several concerns it had regarding both
    Act 82 and Act 138: (1) it still had not received any materials
    regarding Act 82; (2) the copy of Act 138 and certificate had been
    submitted after the seven-business-day period mandated by statute;
    (3) the Commonwealth had failed to provide the required formal
    estimate for Act 138; and (4) both Acts may be preempted by federal
    law.   The Board requested that the Commonwealth submit the missing
    materials, including, specifically, "a formal estimate of the
    - 11 -
    impact each Act will have on expenditures and revenues, including
    the impact on the government's medical insurance plan ('Vital')"
    and "an analysis of [the Acts] in relation to the corresponding
    federal statutes to ascertain there are no conflicting provisions
    that may jeopardize the grant of federal funds to the [Department
    of Health]."      The Board noted that it "reserve[s] the right to
    take   such    actions   as   we   consider   necessary   .   .   .   including
    preventing the enforcement or application of" the Acts if it
    ultimately determines the Commonwealth has "failed to comply with
    our directive . . . or that [the] law[s] impair[] or defeat[] the
    purposes of PROMESA."
    On November 18, 2019, more than three months after it
    was due, the Commonwealth submitted the following certification
    for Act 82:
    Legislative Measure Number:
    •    Act No. 82-2019 ("Act 82"), herein attached.
    Estimate of Impact of the Legislative Measure on Expenditures
    and Revenues:
    •    Act 82 has an approximate impact of $475,131.47 in the
    Department of Health's budget.     However, Act 82 will be
    implemented using budgeted resources.    If reprogramming of
    budgeted resources is needed, the appropriate agency will
    submit to the [Board] a formal request.
    •    Act 82 has no impact on revenues.
    Determination of the Legislative Measure's Compliance with the
    Fiscal Plan:
    - 12 -
    •    Act 82 is not significantly inconsistent with the 2019 Fiscal
    Plan for Puerto Rico.
    A few days later, the Commonwealth responded to the
    Board's November 15 letter.   The Commonwealth began by emphasizing
    its commitment to complying with section 204(a) of PROMESA, noting
    the then-Governor's recent Executive Order mandating compliance
    with that provision.     However, the Commonwealth did not address
    the substance of the Board's concerns in its November 15 letter
    other than to vigorously contest the Board's ability to press the
    Commonwealth as to whether Acts 82 and 138 are preempted by federal
    law.     In making its point that the consideration of possible
    federal preemption was outside the scope of the certification
    process, the Commonwealth insisted that
    Section 204(a)(3) only allows the Board to send
    notifications to the elected government under limited
    circumstances, specifically, if no certifications are
    sent or, if the Board understands an enacted law is
    significantly inconsistent with the certified fiscal
    plan.
    In a December 18 response letter, the Board reiterated
    its concern that the Commonwealth was not complying with the
    section 204(a) requirements by failing to submit all required
    materials and submitting some materials after the seven-business-
    day deadline.   The Board further asserted that the impact estimate
    for Act 82 was not sufficiently "formal" and was "not accurate"
    because "it provide[d] only an 'approximate impact' of the law on
    - 13 -
    the Department of Health's budget" and was "dramatically at odds
    with other authority on the subject; specifically, the Health
    Insurance Administration's recent testimony at [a] public hearing
    that [Act 82] would increase the Government's health plan budget
    by $27 million."        Regarding the preemption issue, the Board
    insisted that requiring a preemption analysis was consistent with
    section 204(a) because "if an enacted law negatively impacts the
    Commonwealth's budget because of conflicts with federal statutes,
    the law would not be consistent with the certified Fiscal Plan."
    In a subsequent letter, the Commonwealth continued to
    assert that it had complied with its obligations under section
    204(a) because it had "not received any notification [from the
    Board] that [the Acts] are significantly inconsistent with the
    Fiscal Plan."   The Commonwealth also maintained that the Board had
    no authority to either determine that the Acts are preempted by
    federal law or require the Commonwealth to consider whether they
    are   so   preempted.     Finally,   the   Commonwealth   rejected   the
    suggestion that Act 82's estimate was "not accurate" because it
    was   "dramatically     at   odds"    with    the   Health    Insurance
    Administration's testimony at the public hearing.            Rather, it
    asserted, "any statement by an agency during the legislative
    process is subordinate to the determination of the appropriate
    government entities" -- AAFAF, OMB, and Treasury -- "in charge of
    issuing the [section 204(a)] certifications."
    - 14 -
    In a letter dated April 27, 2020, the Board stated that
    it   had    conducted         its    own    analysis    of     the   Acts   because    the
    Commonwealth had "so far failed to confirm that its analysis took
    into account germane factors pertaining to [the Acts] and their
    impact on federal funding."                 Based on its own analysis, the Board
    posed a series of detailed questions "regarding the financial
    assumptions on which the laws appear to be based."                          For example,
    for both Acts, the Board asked, "How will the potential impact
    from increases in PMPM [Per Member Per Month] rates be mitigated
    to maintain compliance with the Certified Commonwealth Fiscal
    Plan?"7      The Board requested that the Commonwealth address its
    specific questions as part of formal estimates to be submitted no
    later      than    May    8,        2020.      The     Board     further    noted      that
    "implementation          of    [the    Acts]    prior    to     satisfaction      of   the
    requirements of Section 204 would impair and defeat the purposes
    of PROMESA" and warned that it could take further action, including
    "seeking remedies for preventing" the Acts from being implemented.
    The    Commonwealth            again    responded       that   "no   revised
    certifications are necessary" because, among other contentions,
    7Generally, the PMPM rate is the "predetermined amount" that
    managed healthcare "plans are paid . . . per member per month [to]
    manage and pay for all services included in the benefit package."

    section 204(a) requires only a "'good faith' effort to determine
    the   financial   effects   of    a    new     law"   and   the   certifications
    "include[d] all of the required elements under section 204(a)(2)
    and were provided in good faith."            The Commonwealth also asserted,
    despite    its    mention    in       the      certification       of   possible
    reprogramming, that because Act 82 would be "implemented using
    budgeted resources," a formal request for reprogramming would not
    be required.
    2.   Act 176
    Act 176, signed into law on December 16, 2019, amends
    the "Government of Puerto Rico Human Resources Administration and
    Transformation Act" and the "Fiscal Plan Compliance Act" to undo
    reductions in the accrual rates of vacation and sick days for
    public employees.8    The Commonwealth asserts that the reductions
    in leave had "negatively affected the public employees who are
    entering the workforce because they have no time to spend with
    their loved ones which, in turn, affects their family life."
    On December 26, 2019, the Commonwealth submitted to the
    Board a copy of Act 176 and the following certification:
    Legislative Measure Number:
    •   Act No. 176-2019 ("Act 176"), herein attached.
    8A prior law, Act 8-2017, reduced the accrual rates for
    certain public employees.
    - 16 -
    Estimate of Impact of the Legislative Measure on Expenditures
    and Revenues:
    •   Act 176 amends Act 8-2017, known as the "Government of Puerto
    Rico Human Resources Administration and Transformation Act,"
    and Act 26-2017, known as the "Fiscal Plan Compliance Act,"
    in order to allow government employees to accrue 2.5 vacation
    days and 1.5 sick days per calendar month.
    •   The accrual caps for vacation and sick days remain at 60 and
    90 days respectively. Additionally, Act 176 does not alter
    the prohibition established in Act 26-2017, with regard to
    the liquidation of vacation days accumulated in excess of the
    60 days statutory limit.
    •   As prior to its enactment, government employees may only
    liquidate vacation days when there is a cessation from
    service.    Act 176 does not allow public employees the
    liquidation of sick days.
    •   In addition, every governmental entity and instrumentality is
    required to formulate and manage a personnel vacation plan
    for each calendar year, which shall be strictly complied with
    by all employees, in order to ensure that said employees do
    not accumulate excess vacation days, while ensuring that the
    services provided by the corresponding governmental entities
    and instrumentalities are not interrupted.
    •   Consequently, insofar as Act 176 merely adjusts the accretion
    of vacation and sick days for public employees, but while
    strictly adhering to the liquidation prohibitions established
    in the 2019 New Fiscal Plan for Puerto Rico and Act 26-2017,
    we conclude that Act 176 has no impact on expenditures.
    •   Act 176 has no impact on revenues.
    Determination of the Legislative Measure's Compliance with the
    Fiscal Plan:
    •   Act 176 is not significantly inconsistent with the 2019 Fiscal
    Plan for Puerto Rico.
    On May 11, 2020, the Board informed the Commonwealth
    that it had failed to submit the required formal estimate in that
    the certification "fails to account for Act 176's impact on
    employee productivity, given that it permits employees to take
    more vacation days during the year."    The Board estimated that "if
    - 17 -
    full-time employees utilize all of the additional days Act 176
    makes available to them (12-21 days depending on employee group),
    there could be a productivity loss of approximately five percent,
    which   in    Fiscal     Year   2021        is    akin      to    losing   the   full-time
    equivalent production of 2,400 public employees."                                The Board
    therefore directed the Commonwealth to submit a "complete formal
    estimate by May 19, 2020 taking lost productivity into account."
    The Board stated that "implementation of Act 176[] prior to
    satisfaction of the requirements of Section 204 would impair and
    defeat the purposes of PROMESA" and expressly "reserve[d] the right
    to    take    such    actions     as    it       considers        necessary"     including
    preventing Act 176's implementation.
    A week later, the Commonwealth responded, vigorously
    defending      the     completeness         of        the   submitted      certification.
    Specifically, the Commonwealth disputed the need to "account for
    any   speculative       decrease       in    'employee           productivity'"     because
    section      204(a)    requires    only          an    estimate      of    the   impact   on
    expenditures and revenues and the certificate "does exactly that."
    The Commonwealth went on to assert that the existing caps on the
    accrual      and     liquidation       of    vacation        and    sick    days,   and    a
    requirement that every governmental entity create personnel plans
    to manage the use of vacation days, rendered the Board's employee
    productivity concerns illusory.

    3. Act 47
    Act 47, signed into law on April 26, 2020, amends the
    "Puerto Rico Incentives Code" to expand the scope of healthcare
    professionals who are eligible for incentive tax benefits.     The
    Commonwealth asserts that Act 47's purpose is to encourage more
    medical professionals to enter practice and to stem the "flight"
    of healthcare professionals from Puerto Rico.
    On May 4, 2020, the Commonwealth submitted to the Board
    the following certificate:
    Legislative Measure Number:
    •   Act No. 47-2020 ("Act 47"), herein attached.
    •   Act 47 incorporates technical adjustments to Sections
    1020.02(10), 2021.03(a) and 2023.02 of the Puerto Rico
    Incentives Code in order to provide tax incentives to more
    categories of health professionals. This legislation serves
    the   public  interest   by  promoting   the  retention  of
    professionals in the health field[;] such a feat is
    particularly relevant in light of the COVID-19 pandemic.
    Estimate of Impact of the Legislative Measure on Expenditures
    and Revenues:
    •   Act 47 has no impact on expenditures.
    •   Act 47 could have an estimated annual impact on revenues [of]
    $25.7 million dollars. However, said amount will depend [on]:
    (1) medical professionals that request tax incentives; (2)
    medical professionals ultimately approved to receive such
    incentives in light of the requisites; and (3) income
    ultimately reported by the qualified professionals. In other
    words, the impact provided by the Puerto Rico Department of
    the Treasury consists in an educated estimate that must [be]
    revised on an annual basis in order to provide an accurate
    impact on the revenues.
    Determination of the Legislative Measure's Compliance with the
    Fiscal Plan:
    - 19 -
    •   Act 47 is not significantly inconsistent with the 2019 Fiscal
    Plan for Puerto Rico.
    On May 21, 2020, the Board responded that the certificate
    lacked "even the barest specificity" regarding Act 47's fiscal
    impact.     The Board took specific issue with the suggestion that
    Act 47's impact would be constant over the five-year term of the
    2019 Fiscal Plan despite the Commonwealth's statement that the
    impact estimate "must [be] revised on an annual basis" due to the
    variables     identified.       The    Board      also   challenged    the
    Commonwealth's determination that Act 47 was not significantly
    inconsistent with the fiscal plan, opining that "it [is] difficult
    to understand how the Act, which the Government itself estimates
    will reduce revenue by tens of millions of dollars per year,
    without any corresponding cut in spending or proposal to increase
    revenues    from   other    sources,   can   be    anything   other   than
    significantly inconsistent with the certified Fiscal Plan."            For
    these reasons, the Board requested that the Commonwealth submit a
    "complete formal estimate . . . identifying," among other key
    variables, "[m]inimum and maximum estimates of the percentage of
    medical practitioners applying for th[e] incentive."
    On May 28, the Commonwealth submitted what it termed a
    "revised estimate," indicating that the Act could have a minimum
    annual cost of $540,000 and a maximum annual cost of $40.1 million
    (approximately $200 million over the period of the fiscal plan),
    - 20 -
    based on 7,188 potentially eligible medical professionals.                  The
    Commonwealth continued to maintain, however, that the Act was not
    significantly inconsistent with the fiscal plan given the plan's
    projected revenues of over $20 billion per fiscal year.               That is,
    the Commonwealth asserted that even $40 million a year is, in the
    context of overall projected revenues, a relatively small amount
    and could not be a "significant" deviation from the fiscal plan.
    On June 5, the Board responded that the Commonwealth's submission
    "inappropriately minimizes the economic impact" of the Act and
    that "[v]iewing the costs of [the] Act [] in their proper context,
    meaning   relative      to    the   Commonwealth's      own-source   revenues,
    demonstrates that they are substantial."              The Board concluded by
    warning that "[c]ontinuing to implement Act 47 as it is written,
    or   proceeding    to    go     forward    with    similarly   significantly
    inconsistent    legislation         notwithstanding     objections   from   the
    Oversight Board grounded in PROMESA, will lead the Oversight Board
    to have no choice but to seek judicial relief."
    C.   Procedural Background
    On June 12, 2020, the Commonwealth filed suit in federal
    court seeking, in relevant part, a declaratory judgment that, for
    each of the four laws in question, the Commonwealth had complied
    with section 204(a)'s formal estimate and fiscal plan compliance
    certification     requirements.           The   Board    subsequently    filed
    counterclaims     requesting          injunctive      relief   barring      the
    - 21 -
    implementation and enforcement of each law.9      The Commonwealth
    moved for summary judgment on its claims related to Acts 138
    (amending the health insurance code) and 176 (undoing reductions
    in vacation and sick days).10    The Board filed cross-motions for
    summary judgment as to Acts 138 and 176, motions for summary
    9  Among its counterclaims, the Oversight Board sought
    "nullification" of each law.      The district court eventually
    dismissed all claims for "nullification" because the Board "ha[d]
    not demonstrated that such drastic relief [was] warranted under
    the particular circumstances." 511 F. Supp. 3d at 128, 131, 133,
    138. Neither side raises the "nullification" claims on appeal,
    and we do not address them further.
    The Commonwealth also sought declarations that the Oversight
    Board cannot "unilaterally" invalidate a law and must seek judicial
    relief under § 2124(k) to enjoin a law's implementation. In other
    words, the Commonwealth sought declarations that the mere
    invocation by the Board of noncompliance with PROMESA did not have
    any legal effect in and of itself. The district court eventually
    dismissed these counts given the court's disposition of the Board's
    summary judgment motions. The Commonwealth does not address these
    dismissals on appeal.     However, we note the district court's
    statement that "[a] proper declaration of a negative section
    108(a)(2) determination by the Board [i.e., that a law would impair
    or defeat the purposes of PROMESA] triggers a statutory prohibition
    on action by the Government to go forward with the targeted
    statute, . . . but it does not empower the Oversight Board
    unilaterally to void the legislation or create an injunction." In
    re Fin. Oversight & Mgmt. Bd. for P.R., 
    511 F. Supp. 3d 90
    , 134
    (D.P.R. 2020).
    10 After the Commonwealth's commencement of the legal
    proceedings, the Oversight Board inquired as to whether the
    Commonwealth had implemented any of the challenged Acts
    "notwithstanding the Oversight Board's instructions to the
    contrary pursuant to several provisions of PROMESA."           The
    Commonwealth responded that the Acts had either been fully
    implemented, partially implemented, or it was the intention of the
    Commonwealth to implement them, despite the ongoing dispute with
    the Board.
    - 22 -
    judgment on the Commonwealth's claims as to Acts 82 (regulating
    pharmacy reimbursement for medications) and 47 (increasing tax
    incentives for medical professionals), and motions for summary
    judgment on its counterclaims.    In its opposition to the Board's
    summary judgment motions regarding Acts 82 and 47, the Commonwealth
    requested an order deferring a ruling and allowing additional
    discovery pursuant to Federal Rule of Civil Procedure 56(d).
    In its decision on the summary judgment motions, the
    court (1) reiterated its holding in Law 29 II that it would apply
    arbitrary and capricious review to the Board's determination under
    section 108(a)(2) that a law's implementation would impair or
    defeat the purposes of PROMESA; and (2) held that it would also
    apply   arbitrary     and   capricious   review   to   the   Board's
    determinations under section 204(a) that the Commonwealth had
    failed to comply with its obligations to submit "formal estimates"
    and certifications.    In so holding, the district court rejected
    the Commonwealth's invitation to apply a distinct "substantial
    evidence" standard under Puerto Rico law.   The Commonwealth argued
    that such a standard should apply because of the Supreme Court's
    holding that the Board is an entity within the government of Puerto
    Rico.   See Fin. Oversight & Mgmt. Bd. for P.R. v. Aurelius Inv.,
    LLC (In re Fin. Oversight & Mgmt. Bd. for P.R.), 
    140 S. Ct. 1649
    ,
    1659 (2020) ("Aurelius").   The district court, however, noted that
    "[t]he Aurelius decision was focused narrowly on the applicability
    - 23 -
    of the Appointments Clause and does not undermine this [c]ourt's
    prior reasoning about the level of deference properly afforded to
    the Oversight Board determinations on account of the Oversight
    Board's 'operational similarity' to a federal agency."      In re Fin.
    Oversight & Mgmt. Bd. for P.R., 
    511 F. Supp. 3d 90
    , 121 (D.P.R.
    2020) (quoting Law 29 II, 616 B.R. at 252).
    Applying the "arbitrary and capricious" standard of
    review,     the    district   court   concluded   that   the   Board's
    determinations regarding the Commonwealth's noncompliance with
    section 204(a), and its determinations that the challenged laws
    would impair or defeat PROMESA's purposes, were not "arbitrary and
    capricious."      Regarding the Commonwealth's requests for discovery
    concerning Acts 82 and 47, the court stated that the Commonwealth
    had not "demonstrated that it lacks access to any evidence relating
    to any material fact that is necessary to oppose" the Board's
    motions.    Id. at 127 n.22, 138 n.35.    The court therefore enjoined
    the implementation and enforcement of all four laws, with a
    recognition that it could revisit such relief "if there emerge any
    significant changes in legal or factual conditions."       Id. at 128
    n.23, 131 n.28, 133 n.30, 138 n.36.          The Commonwealth timely
    appealed.
    II.
    We review a district court's grant of summary judgment
    de novo.    López-Santos v. Metro. Sec. Servs., 
    967 F.3d 7
    , 11 (1st
    - 24 -
    Cir. 2020).        Summary judgment is appropriate if the record,
    construed in the light most favorable to the nonmovant, presents
    no genuine issue of material fact and demonstrates that the movant
    is entitled to judgment as a matter of law.             Id.; Fed. R. Civ. P.
    56(a).    It is well-established that "[c]ross-motions for summary
    judgment do not alter the summary judgment standard, but instead
    simply 'require us to determine whether either of the parties
    deserves judgment as a matter of law on the facts that are not
    disputed.'"      Wells Real Est. Inv. Tr. II, Inc. v. Chardon/Hato Rey
    P'ship, S.E., 
    615 F.3d 45
    , 51 (1st Cir. 2010) (quoting Adria Int'l
    Grp., Inc. v. Ferré Dev., Inc., 
    241 F.3d 103
    , 107 (1st Cir. 2001)).
    Applying the "arbitrary and capricious" standard of
    review,    the    district    court     evaluated      whether      the   Board's
    determinations      were   "reasoned[]    and   supported      by    substantial
    evidence in the record."         511 F. Supp. 3d at 120.            Although the
    Commonwealth      now   agrees   on    appeal   that    the    "arbitrary     and
    capricious" standard applies, it argues that this means more than
    just considering whether the Board's determinations were reasoned
    and supported by substantial record evidence.11               The Commonwealth
    11  Even in rejecting application of the Puerto Rico
    "substantial evidence" standard in favor of arbitrary and
    capricious review, the district court questioned whether there is
    "actually a difference between the two standards." 511 F. Supp.
    3d at 121. As the district court explained, "[t]he Puerto Rico
    'substantial evidence' standard requires [such] 'relevant evidence
    as a reasonable mind might accept as adequate to support a
    conclusion.'"   Id. at 121-22 (quoting SPRINTCOM, Inc. v. P.R.
    - 25 -
    contends     that   "arbitrary   and   capricious"     analysis    must     also
    consider     attendant   principles     developed    through      decades     of
    administrative law jurisprudence.        Specifically, it contends that
    the Board (1) "must [have] explain[ed] the standard on which it
    bases its determination" (citing, inter alia, ACA Int'l v. FCC,
    
    885 F.3d 687
    ,    700   (D.C.     Cir.   2018))     (2)      "must     have
    contemporaneously and reasonably explained its decision" (citing,
    inter alia, Motor Vehicle Mfrs. Ass'n of U.S., Inc. v. State Farm
    Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 48-49 (1983)); and 3) may not
    rely on "hindsight rationalizations" (citing, inter alia, DHS v.
    Regents of the Univ. of Cal., 
    140 S. Ct. 1891
    , 1909 (2020)).
    By contrast, the Board contends that even if we assess
    whether its determinations were "arbitrary and capricious," we
    should not apply "the entire apparatus of administrative law."12
    Reguls. & Permits Admin., 
    553 F. Supp. 2d 87
    , 91-93 (D.P.R. 2008)).
    The court opined that this standard of adequate evidence "is
    appropriately considered as part of arbitrary and capricious
    review." 
    Id. at 122
    .
    12On appeal, for the first time, the Board argues in the
    alternative that we should apply a highly circumscribed "ultra
    vires" standard of review to its decisions. But the Board waived
    this argument by not raising it before the district court and by
    repeatedly asserting before that court that "arbitrary and
    capricious" review applied.    See, e.g., 20-00080-LTS, Dkt. #16,
    8-10 (Oct. 5, 2020); Bos. Redev. Auth. v. NPS, 
    838 F.3d 42
    , 47
    (1st Cir. 2016) ("Having urged one standard of review in the
    district court, [a party] cannot now repudiate its earlier position
    and seek sanctuary in a different standard."). Moreover, raising
    a new standard of review for the first time on appeal, after the
    Commonwealth had already submitted its opening brief, does not
    reflect well on the Board and is inconsistent with the respect it
    - 26 -
    That   is,    the     Board    argues       that    "principles      from       federal
    administrative        law   that    apply    to    agencies    --   the   rule     that
    administrative agencies must offer contemporaneous reasons for
    their actions, the ban on hindsight rationalization, and the
    requirement      to     articulate       consistent      standards        for     their
    determinations" -- do not apply here because the Board is not a
    federal agency.
    We see logic on both sides.              On the one hand, PROMESA
    provides that the Oversight Board should be treated as an entity
    within the territorial government, not a federal agency, 
    48 U.S.C. § 2121
    (c)(1)-(2); territorial governments are expressly excluded
    from the definition of "agency" in the Administrative Procedure
    Act ("APA"), 
    5 U.S.C. § 701
    (b)(1)(C); and the administrative law
    principles      cited   by    the    Commonwealth      have    developed        through
    judicial review of "agency" action pursuant to the APA.                     Further,
    the Board is in many ways a unique entity, which has been given,
    by PROMESA's express language, a tremendous degree of authority
    over aspects of Puerto Rico's financial recovery.
    On the other hand, core administrative law principles
    are not creatures of the APA.            Rather, developed over time, these
    principles promote fairness and transparency in the administrative
    process   and    provide      concrete      guideposts   for    reviewing        agency
    should display in its interactions with the Commonwealth and the
    district court.
    - 27 -
    action.    See, e.g., SEC v. Chenery Corp., 
    332 U.S. 194
    , 196 (1947)
    (describing as a principle predating the APA's passage the "simple
    but fundamental rule of administrative law . . . that a reviewing
    court    . . . must judge the propriety of [agency] action solely by
    the grounds invoked by the agency").                As the district court
    recognized, there is clear "operational similarity" between the
    Board and a federal agency.          In basic terms, both have been charged
    by   Congress      with      using     their   statutory     authority     and
    organizational expertise to implement the terms of a complex
    statute.    It stands to reason that the principles used to review
    whether a federal agency decision is arbitrary or capricious could
    also be useful in evaluating a decision by the Board.
    All that said, to decide this appeal, we need not settle
    to what extent the universe of federal administrative law should
    be applied in reviewing Board determinations.                     We do think,
    however, that some guidance is warranted on one important issue
    -- the extent to which either the Board or the Commonwealth can
    support its position with rationales and analysis proffered for
    the first time during litigation.
    The Commonwealth takes issue with the Board's submission
    during    the   litigation    of     declarations   that,   the    Commonwealth
    claims, provided new justifications for the Board's determinations
    regarding the challenged laws. The district court repeatedly cited
    two such declarations: one by Board Executive Director Natalie A.
    - 28 -
    Jaresko regarding all four laws, and another by independent health
    policy consultant Phillip Ellis stating his conclusion that Act 82
    would increase healthcare costs for the Commonwealth.     See, e.g.,
    511 F. Supp. 3d at 129-30 & nn.25-26.     The Commonwealth contends
    that this reliance was improper.
    "It is a 'foundational principle of administrative law'
    that judicial review of agency actions is limited to 'the grounds
    that the agency invoked when it took the action.'"     Regents of the

    , 758 (2015)).   An agency may later "elaborate" on those
    grounds, but it "may not provide new ones."   Id. at 1908.   In other
    words, an agency must stand by the reasons it provided at the time
    of its decision and cannot rely on post-hoc rationalizations
    developed and presented during litigation.     See Citizens to Pres.
    Overton Park, Inc. v. Volpe, 
    401 U.S. 402
    , 419 (1971) ("The lower
    courts based their review on the litigation affidavits that were
    presented.      These    affidavits    were   merely    'post   hoc'
    rationalizations, which have traditionally been found to be an
    inadequate basis for review." (internal citation omitted)); see
    also State Farm, 
    463 U.S. at 50
    ; Regents of the Univ. of Cal., 140
    S. Ct. at 1908-09.
    There may be good reasons for applying these principles
    to the section 204(a) process.     Requiring the Board to present to
    the Commonwealth all of its rationales for disapproving of a piece
    - 29 -
    of legislation enables the Commonwealth to fairly respond to the
    Board's stated concerns, or to address those concerns based on a
    fuller understanding of the Board's reasoning.                  This enhanced
    communication     between     the   Commonwealth   and   the     Board     could
    conceivably reduce the need for litigation.           If and when a dispute
    does go to court, a fully developed record enables the district
    court to properly assess whether the Board's determinations were
    supported by "substantial evidence" without considering post hoc
    rationalizations.     See Regents of the Univ. of Cal., 140 S. Ct. at
    1908-09.
    However, given the unique nature of the section 204(a)
    process, and the relationship between the Commonwealth and the
    Board under PROMESA, a hard-and-fast rule that the Board never may
    proffer supplementary rationales or analysis during litigation
    would not be appropriate.           This case illustrates one reason why
    this is so.     By taking the Board to court soon after the two sides
    had   reached   an   impasse,    the   Commonwealth   short-circuited        the
    process, particularly as to Acts 176 and 47, considering that the
    Commonwealth filed suit just weeks after first hearing from the
    Board regarding those laws.         When one side cuts off the process in
    this way by going to court, it is only fair that the other side
    can further develop its position in the litigation.
    Therefore,    in     proceedings   arising    from    the     section
    204(a) review process, the district court should consider, on a
    - 30 -
    case-by-case basis, whether and to what extent it will allow either
    side to support its position with supplementary materials first
    proffered during litigation.        In this case, with one exception
    discussed below, it is not clear that the materials submitted by
    the     Board   in   the   litigation   contained   anything    more   than
    elaboration of rationales the Board had provided in the pre-
    litigation correspondence.        And this elaboration was certainly
    appropriate given that, as we have noted, the Commonwealth was the
    party that ended the correspondence by taking the Board to court.
    We thus conclude that the district court did not err in considering
    the supplementary materials submitted by the Board.            We turn now
    to our de novo review of the district court's judgment as to each
    law.
    III.
    A. Act 82
    Before the district court, the Board generally contended
    that the Commonwealth had failed to comply with the estimate and
    certification requirements of section 204(a) in regard to Act 82
    and that the Act is "significantly inconsistent" with the fiscal
    plan.    The district court ultimately ruled for the Board solely on
    the basis of the Commonwealth's failure to comply with section
    204(a), holding that
    the undisputed factual record, when viewed in the
    light most favorable to the Governor, establishes
    that the Government failed to comply with its
    - 31 -
    statutory responsibility to provide a formal
    estimate and certification that was sufficiently
    informative and complete, such that the Oversight
    Board's determination of noncompliance and its
    ultimate decision to seek injunctive relief under
    section 204(a)(5) after repeated attempts to obtain
    a formal estimate and certification are neither
    arbitrary nor capricious. The only certificate of
    compliance   and   estimate   submitted    by   the
    Government, which together comprise less than half
    a page of text, plainly fall short of even facial
    compliance with the formal estimate requirement;
    they provide no context or analysis to support the
    certification's assertion of consistency with the
    fiscal plan imposed by PROMESA § 204(a).
    In re Fin. Oversight & Mgmt. Bd. for P.R., 511 F. Supp. 3d at 126.
    We agree.13
    Despite the district court's prior explanation, in Law
    29   I,    that   the   formal   estimate   must   cover   the   "revenue   and
    expenditure effects of new legislation" over the entire period of
    the fiscal plan, 403 F. Supp. 3d at 13-14, the Commonwealth
    submitted a conclusory and unsupported estimate that did not even
    purport to account for the duration of the fiscal plan.                As the
    district court accurately observed,            the Commonwealth      provided
    "absolutely no supporting rationale for the impact estimate of
    $475,131.47" and no "clearly articulated compound estimate that
    covers the entire duration of the 2019 Fiscal Plan."             511 F. Supp.
    13In its analysis, the district court declined to consider
    the significance of the fact that the Commonwealth had submitted
    the certifications for Acts 82 and 138 well after the statutory
    seven-day deadline. We also decline to address these timeliness
    issues as they are unnecessary to our decision.
    - 32 -
    3d     at   126.        Nor     did    the     Commonwealth       take   the    "several
    opportunities"          provided      by    the    Board   "to    cure   the   perceived
    deficiencies and provide some sort of substantiation."                           Id. at
    127.        To    the   contrary,      when       the   Board    reasonably    requested
    information about "the financial assumptions on which the law[]
    appear[s] to be based," pursuant to its authority under section
    204(a)(4),        the    Commonwealth         stonewalled.         And   then,    having
    stonewalled, the Commonwealth cut off the exchange and took the
    Board to court.          It was entirely reasonable for the Board to ask
    the court to enjoin implementation of the law, consistent with
    section 204(a), given that the Commonwealth had refused to comply
    with its obligations under that section.
    On   appeal,    the       Commonwealth    emphasizes     the    Board's
    requests in the pre-litigation correspondence that it consider
    whether Act 82 would jeopardize the receipt of federal funds.14
    But the district court did not "reach whether the Board's request
    for such analysis was arbitrary and capricious . . . because the
    In its correspondence with the Board regarding Act 82, the
    14
    Commonwealth repeatedly took issue with the Board's requests that
    it consider whether Act 82 would jeopardize the receipt of federal
    funds.    The Oversight Board consistently maintained in its
    correspondence with the Commonwealth that it "was not asking for
    a preemption analysis" but rather "an analysis of the [Acts] to
    determine whether any provisions jeopardize the grant of federal
    funds to the Puerto Rico Department of Health." Because we need
    not consider the preemption issue, we do not determine whether
    this distinction drawn by the Board is a distinction with a
    difference for purposes of the statutory review process under
    section 204(a).
    - 33 -
    Government's section 204(a) noncompliance is already patent" from
    its refusal to respond to the Board's other questions about Act
    82's fiscal impact.        In re Fin. Oversight & Mgmt. Bd. for P.R.,
    511 F. Supp. 3d at 126 n.20.        We again agree that it is unnecessary
    to consider whether the Commonwealth had to, as part of the "formal
    estimate," account for Act 82's impact on the receipt of federal
    funds.   Even putting this request aside, the Board made reasonable
    requests for the Commonwealth to support its estimate and the
    Commonwealth plainly did not comply.
    The   Commonwealth      attempts    to    rewrite   the   record   by
    suggesting that the Board's entire objection to the estimate and
    certification was based on the federal funds issue and the Board's
    reference    to    "the    Health    Insurance       Administration's    recent
    testimony at [a] public hearing that [Act 82] would increase the
    Government's      health   plan   budget   by    $27   million."      While    we
    acknowledge that the Board did repeatedly press the federal funds
    issue, a fair reading of the record demonstrates that the Board
    expressed a broader concern that the Commonwealth's conclusory
    "approximate impact" estimate was insufficiently supported.               It is
    simply not evident from the record that the Board based its
    objections solely on the federal funds issue, or on the purportedly
    conflicting testimony.
    Finally, the district court did not abuse its discretion
    in denying the Commonwealth's request to defer summary judgment
    - 34 -
    pending further discovery.      See In re PHC, Inc. S'holder Litig.,
    
    762 F.3d 138
    , 142-43 (1st Cir. 2014) (explaining that we review
    the district court's denial of a Rule 56(d) motion for abuse of
    discretion).     Other than a speculative suggestion that further
    discovery would have somehow undermined the Board's bases for
    questioning the Act's fiscal impact, the Commonwealth has not
    pointed to any type of information that would be germane to its
    claims and to which it did not already have access.
    B. Act 138
    As with Act 82, the district court ruled for the Board
    on the basis of its contention that the Commonwealth had failed to
    comply with its obligation under section 204(a).              We again agree
    with the district court's analysis.          For Act 138, the Commonwealth
    submitted    a   conclusory    statement       claiming      "no     impact   on
    expenditures and revenues."       The Board reasonably requested that
    the Commonwealth supply some analysis or data to back up that
    assertion, but the Commonwealth refused to do so.                    Again, the
    Board's     determination     that     the    conclusory       and     entirely
    unsubstantiated   "no   impact"      statement   did   not    constitute      the
    required "formal estimate" was entirely reasonable.                The Board was
    justified in directing the Commonwealth to address how the Act
    would impact expenditures and revenues.           And it was justified in
    determining that, by not submitting a formal estimate or addressing
    - 35 -
    the Board's specific questions, the Commonwealth had failed to
    comply with its obligations under section 204(a).15
    Finally, for the same reasons we expressed in relation
    to Act 82, we reject the Commonwealth's contention that the
    district court abused its discretion by proceeding to rule on the
    summary judgment motions without further discovery.16
    C. Act 176
    The   district   court   concluded   that   the   Board   had
    reasonably determined, pursuant to its authority under section
    108(a)(2), that implementing Act 176 would "impair or defeat"
    PROMESA's purposes.17   In re Fin. Oversight & Mgmt. Bd. for P.R.,
    511 F. Supp. 3d at 133.      In so concluding, the district court
    15Regarding Act 138 and Act 47, which is discussed further
    below, we are cognizant of Puerto Rico's important efforts to
    attract and retain doctors and other medical professionals. We
    encourage the Commonwealth to focus on providing robust
    documentation regarding these efforts as it continues to develop
    incentives for medical professionals to practice on the island.
    16We again need not address the "federal funds" issue because,
    setting that topic of inquiry aside, the Board's requests for more
    analysis   by   the   Commonwealth   were   reasonable,   and   the
    Commonwealth's responses were patently noncompliant.
    17Before the district court, the Board argued both that (1)
    the Commonwealth had failed to meet its obligations under section
    204(a) to submit proper estimates and certifications for the four
    laws; and (2) the four laws in their substantive effect would
    "impair or defeat the purposes of" PROMESA. The district court
    based its ruling on the first ground with respect to Acts 82 and
    138 and, as explained below, on the second ground with respect to
    Acts 176 and 47. On appeal, the Board does not raise the first
    ground as an alternative basis for affirming the district court as
    to Acts 176 and 47.
    - 36 -
    endorsed the Board's stated concern that the law would negatively
    affect expenditures through decreased worker productivity: "Common
    sense and basic principles of economics dictate that, by allowing
    sick days and vacation days to accrue more quickly, without
    reducing pay levels, Act 176 affects expenditures by increasing
    the price the Government pays for labor -- causing the Government
    to pay the same amount of money to each person for fewer days
    worked."   Id. at 132.    The district court further noted that the
    Commonwealth's   recourse to the provision requiring each agency to
    institute plans governing their employees' taking of vacation days
    did not adequately address the Board's concern.
    We   agree   with   both   points.   The   Board   reasonably
    determined that Act 176 would decrease worker productivity --
    resulting in the Commonwealth essentially paying higher labor
    costs to provide services -- and the Commonwealth did not refute
    this determination.      It was thus reasonable for the Board to
    determine that the Act would impair implementation of the fiscal
    plan and PROMESA's purpose of securing the Commonwealth's fiscal
    solvency.18
    18 The Commonwealth urges us to determine the precise meaning
    of "significantly," as in when a law is "significantly inconsistent
    with the Fiscal Plan for the fiscal year". Id. § 2144(a)(1)-(2)
    (emphasis added).    It contends that a law can only "impair or
    defeat the purposes of" PROMESA if it is "significantly
    inconsistent" with the fiscal plan, and that the purported
    inconsistency between the fiscal plan and Act 176 cannot be deemed
    "significant."    We need not determine the precise meaning of
    - 37 -
    The district court also based its decision on the Board's
    contention that Act 176 conflicts with the fiscal plan's goal of
    "right-siz[ing] the workforce to the population size" and ensuring
    that agencies "deliver services in as efficient a manner as
    possible."      Id. at 132.           The Commonwealth contends that these
    rationales were never articulated by the Board during the pre-
    litigation correspondence.             We agree that these rationales were
    first articulated during the litigation and were more than mere
    elaborations     on        the    Board's    stated        concern     about     worker
    productivity.      In the future in such a situation, the district
    court,   mindful      of    traditional      administrative          law    principles,
    should consider whether it is appropriate to accept a new rationale
    in support of the Board's position.                    Here, however, we are not
    troubled   by    the       district    court's         consideration       of   the   new
    rationales.     As we have explained, although it would have been a
    better practice for the Board to have clearly articulated these
    rationales in its correspondence with the Commonwealth, it was not
    inappropriate      for      the   Board     to    supplement     its       reasons    for
    challenging     the        laws    during        the     litigation,        given     the
    Commonwealth's abrupt termination of the section 204(a) process by
    taking the Board to court.
    "significantly." Whatever its precise meaning, Act 176, with its
    sizable projected impacts on expenditures, can reasonably be
    deemed "significantly inconsistent" with the fiscal plan.
    - 38 -
    D. Act 47
    Lastly, the district court ruled in the Board's favor
    regarding Act 47, "[b]ased on [the Board's] determination that the
    loss of tens of millions of dollars" from the expansion of tax
    incentives "would defeat or impair PROMESA's purposes, which was
    communicated to the Government in the course of correspondence
    concerning section 204(a)."     Id. at 136.       The district court
    explained that "[t]he fact that Act 47 has the undisputed potential
    to reduce revenues by about $200 million over five years by
    creating tax incentives with no offsets to make it revenue neutral
    renders its implementation a flagrant and significant deviation
    from" the fiscal plan's principle of "revenue neutrality."    Id. at
    137.    We again agree with the district court.   Simply put, it was
    reasonable for the Board to determine that a law that could reduce
    revenues by up to $200 million with no corresponding offsets would
    "impair or defeat the purposes of" PROMESA.
    The Commonwealth makes much of the fact that, in its
    pre-litigation correspondence, the Board did not specifically cite
    section 14.3.3, the provision regarding "revenue neutrality" in
    the 2019 fiscal plan.19     But the Board expressly stated in its
    The principle of revenue neutrality for tax measures, which
    19
    is also in the 2020 Fiscal Plan, see 2020 Fiscal Plan at 218,
    provides that "any tax reform or tax law initiatives that the
    Government undertakes must be revenue neutral, that is, all tax
    reductions must be accompanied by offsetting revenue measures of
    - 39 -
    letter regarding Act 47 that "it [is] difficult to understand how
    the Act, which the Government itself estimates will reduce revenue
    by tens of millions of dollars per year, without any corresponding
    cut in spending or proposal to increase revenues from other
    sources, can be anything other than significantly inconsistent
    with the certified Fiscal Plan." Given this description of revenue
    neutrality in all but name and the reference to the fiscal plan,
    we cannot conclude that the Commonwealth was unaware of the Board's
    revenue neutrality-based objection before the litigation.       In
    other words, the revenue-neutrality issue was not truly raised for
    the first time during litigation and we are not troubled by the
    district court's consideration of this rationale.20   We conclude,
    then, for the same reasons articulated by the district court, that
    the Board reasonably determined that Act 47 would "impair or defeat
    the purposes of" PROMESA.21
    a sufficient amount identified in the enabling legislation," 2019
    Fiscal Plan at 124.
    20 Because we think it plain that a law that reduces revenues
    by up to $200 million with no offsetting measures is "significantly
    inconsistent" with the fiscal plan and would "impair or defeat the
    purposes of" PROMESA, we need not, and do not, opine as to whether
    the Board could seek to enjoin any law that technically violates
    revenue neutrality, no matter how minimal the revenue reduction.
    21 The Commonwealth argues, in one paragraph of its brief,
    that the Oversight Board had a responsibility to "explain its
    change of position" because "[b]efore Act 47's passage, the Board's
    Municipal Affairs and Legislative Review Director had assured the
    Governor's Legislative Affairs Adviser that the Board had 'no
    issue' with Act 47." Even assuming this argument was preserved
    and is sufficiently developed before us, the Commonwealth has not
    - 40 -
    ***
    In summary, then, in the case of all four laws, we
    conclude that the Board did not act arbitrarily and capriciously
    in exercising its authority under PROMESA.    To the contrary, the
    Board reasonably determined that the Commonwealth had either not
    met its obligations under section 204(a) to provide a "formal
    estimate" and certification (Acts 82 and 138), or that the laws
    would "impair or defeat the purposes of" PROMESA (Acts 176 and
    47). The procedures and obligations contemplated by section 204(a)
    are not procedure for procedure's sake.    Rather, they serve the
    critical purpose of allowing the Board to determine that the
    legislation at issue adheres to the fiscal plan and will not impair
    PROMESA's purpose of restoring Puerto Rico to fiscal stability.
    We therefore affirm the district court's judgment with respect to
    all four laws.22
    demonstrated that this preliminary "assurance" from one official
    to another was sufficiently formal such that the Board's later
    position was indeed an "abrupt about face" meriting explanation.
    Cf. FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515 (2009)
    (noting that an agency usually must provide some recognition of,
    and explanation for, a change in agency policy).
    22 The Commonwealth also argues that the Oversight Board
    violated a norm of administrative law by not "treating like cases
    alike" when it objected to Acts 82, 138, and 176. Even if we were
    to accept the application of this "norm" to the Board's actions,
    it is not clear to us that this argument was raised before the
    district court, and we would therefore deem it waived.     To the
    extent the argument was preserved, it is fatally underdeveloped.
    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."). The

    IV.
    Congress     had   to   make    difficult   choices    in    writing
    PROMESA and responding to Puerto Rico's fiscal crisis.                 One of
    those choices was giving the Board the authority to review and
    block the implementation of         laws   enacted by the       Puerto Rico
    legislature if they "impair or defeat the purposes of" PROMESA.
    We   recognize   the   Commonwealth's       objections   to     this   unique
    structure.   But that is the governing structure that applies here.
    The Board did not act "arbitrarily and capriciously" in exercising
    its authority under PROMESA.23
    Affirmed.     Each side to bear its own costs.
    Commonwealth merely cites to several other certifications that
    were accepted by the Board and asserts that these "other laws had
    a   demonstrated,   non-speculative    fiscal   effect   or   their
    certificates included similar levels of analysis." Asking us to
    perform this context-less comparison is simply asking us to do too
    much in building the Commonwealth's argument.      See 
    id.
     (noting
    that counsel cannot "leav[e] the court to do counsel's work, create
    the ossature for the argument, and put flesh on its bones").
    23 We are disheartened by the antipathy between the parties
    that was evident in the briefing and at oral argument. In the
    future, we hope that the Commonwealth and the Board will recommit
    to working together in a non-adversarial fashion so that this type
    of litigation can be avoided, in the best interests of the people
    of Puerto Rico.
