    The opinion of the court was delivered by
    FASCIALE, J.A.D.
    In   the   wake   of   the   New       Jersey   Supreme   Court's   order
    requiring judicial oversight of municipal housing obligations to
    preclude exclusionary development schemes, see In re Adoption of
    N.J.A.C. 5:96 & 5:97 by the New Jersey Council on Affordable
    Housing, 
    221 N.J. 1
    (2015) (In re N.J.A.C. 5:96 II), we granted
    3                            A-3323-15T1
    the Township of Barnegat's1 motion for leave to appeal from an
    interlocutory order entered by a designated Mount Laurel2 judge,
    directing the court's Special Regional Master to include, as a
    new,   "separate   and   discrete"   component,    an   additional
    calculation for establishing a municipality's affordable housing
    need from 1999 to 2015 (the gap period).3   In entering the order,
    the judge concluded that a municipality's fair share affordable
    housing obligation for the third-round cycle is comprised of (1)
    its newly-created, court-imposed, "separate and discrete" gap-

    The February 18, 2016 order includes a signature of another
    judge who handled two of these thirteen consolidated matters,
    and who joined the opinion of the Mount Laurel judge. Reference
    in our decision to the "court" or "judge" refers to the Mount
    Laurel judge who entered the order and rendered the opinion

    period obligation; (2) unmet prior round obligations from 1987
    to 1999; (3) present need; and (4) prospective need.
    We granted amicus status to the following entities that
    urged us to reverse the order: Colts Neck Township; Township of
    Millstone; Township of Middletown; Township of South Brunswick;
    The Municipal Consortium; and the Municipal Group.4                               The New
    Jersey    State   League      of   Municipalities           (NJLM)   also      appeared
    before the court as a respondent.
    These entities contend the court is without legal authority
    to   create   a   "separate        and   discrete"       gap-period      obligation.
    Instead, they maintain that a municipality's affordable housing
    obligation for the third-round cycle is comprised of unmet prior
    round    obligations     from       1987       to   1999,     present        need,      and
    prospective need.        They argue that prospective need projects
    into the future a town's housing obligation for ten years from
    the current time, not from the beginning of the gap period in
    1999.    They acknowledge that the identifiable housing need that
    arose    during   the   gap    period      would    be   captured       by    a    town's
    present need obligation, but they are adamant that there is no
    "separate and discrete" gap-period obligation.

    The Municipal Group is a formal coalition of hundreds of
    municipalities organized to address fair share methodological
    issues in the aftermath of the Court's opinion in In re N.J.A.C.
    5:96 II.
    5                                      A-3323-15T1
    We granted amicus status to the following entities that
    urged us to affirm the order:                Disability Rights New Jersey; the
    New Jersey Chapter of the American Planning Association; New
    Jersey     Future;    and      the    Housing          and    Community      Development
    Network.
    Fair Share Housing Center (Fair Share), New Jersey Builders
    Association      (NJBA),       and    Highview         Homes,     L.L.C.      (Highview)
    appeared before the court as intervenors and, pursuant to In re
    N.J.A.C.    5:96     II,     Fair    Share       participated     as    an    interested
    party.      Fair     Share    agrees       that    a    municipality's        affordable
    housing obligation for the third-round cycle is comprised of
    unmet prior round obligations from 1987 to 1999, present need,
    and   prospective      need.         Fair     Share      concedes      that    a     town's
    prospective need requires calculations projecting forward ten
    years.     Fair Share asserts, however, that prospective need also
    requires     a     municipality        to        perform      housing      calculations
    retroactively      during     the    gap     period.          Therefore,      Fair    Share
    maintains    that     gap-period       housing         need   comprises       part    of    a
    town's calculation of its prospective need.                       As a result, Fair
    Share defines prospective need differently than those entities
    urging us to reverse the order.                     For Fair Share, prospective
    need covers a period of twenty-seven years: from 1999 to the
    present, and then ten years into the future.                              Thus, to the
    6                                     A-3323-15T1
    extent a municipality is required to establish its prospective
    need from 1999 to the present, and then ten years into the
    future,    Fair    Share     urges     us       to          uphold       the    court-imposed
    "separate and discrete" gap-period housing obligation.
    The narrow legal issue on appeal is whether a "separate and
    discrete" gap-period affordable housing obligation is authorized
    by (1) the core principles of the Mount Laurel doctrine, as
    codified in the Fair Housing Act of 1985 (FHA), N.J.S.A. 52:27D-
    301 to -329; and (2) In re N.J.A.C. 5:96 II.                             Resolution of this
    legal question specifically addresses whether a municipality's
    prospective     need   involves       a     retroactive                housing       obligation
    starting in 1999.      Our focus, therefore, is on the propriety of
    the   court's     conclusion    that       such         a       "separate      and   discrete"
    obligation is "constitutionally mandated."
    Applying the core principles of the Mount Laurel doctrine
    and the plain language of the FHA, including its unambiguous
    definition    of   "prospective       need"         —       a    forward       "projection    of
    housing    needs     based     on    development                 and     growth      which    is
    reasonably    likely   to    occur     in       a    region         or    a    municipality,"
    N.J.S.A.   52:27D-304(j)       —     and    following              the     Supreme      Court's
    admonition not to become an alternative administrative decision
    maker for unresolved policy issues surrounding the Third Round
    Rules, we hold that the FHA does not require a municipality to
    7                                          A-3323-15T1
    retroactively calculate a new "separate and discrete" affordable
    housing obligation arising during the gap period.                 Pursuant to
    In re N.J.A.C. 5:96 II, "previous methodologies employed in the
    First and Second Round Rules should be used to establish present
    and prospective statewide and regional affordable housing need,"
    and prior round unfulfilled obligations "should be the starting
    point   for   a    determination     of     a   municipality's    fair    share
    responsibility."         
    Supra, 221 N.J. at 30
    (emphasis added).              As
    the Court instructed, subject to the guidelines and principles
    it outlined in In re N.J.A.C. 5:96 II, Mount Laurel judges
    may confidently utilize similar discretion
    [used by the Council on Affordable Housing
    (COAH)]   when assessing a town's plan, if
    persuaded that the techniques proposed by a
    town will promote for that municipality and
    region the constitutional goal of creating
    the realistic opportunity for producing its
    fair share of the present and prospective
    need for low- and moderate-income housing.
    [Ibid. (emphasis added).]
    We emphasize that under our tripartite system of government, the
    imposition    of    a    new   retrospective     calculation,     designed    to
    establish affordable housing need during the gap period — a new
    methodology       that    essentially       addresses    "unresolved     policy
    details of replacement Third Round Rules" — is best left for
    consideration      by    the   Legislative      and   Executive   branches    of
    government, where public policy issues associated with such an
    8                              A-3323-15T1
    additional "separate and discrete" obligation can be fairly and
    fully debated in the public forum.                             The Legislature may craft
    new legislation addressing any gap period between housing cycles
    if   that     is   the     course       it    wishes         to    take.     Enforcement      of
    subsequent legislation promoting affordable housing needs — and
    its effect on a municipality's Mount Laurel obligation — would
    still be a matter that may be brought to the courts.
    The judge did not determine whether any of the town's plans
    will        satisfy        their        constitutional                  affordable     housing
    obligations.          At this point in the litigation, his main legal
    concern      was    whether        to    impose          a     "separate      and    discrete"
    affordable housing obligation for the gap period, in addition to
    a    town's        unmet     prior           round,          present,      and      prospective
    obligations.        Having resolved that legal question, the judge may
    now determine whether the towns have met their constitutional
    goal of creating "[a] realistic opportunity for producing its
    fair share of the present and prospective need for low- and
    moderate-income housing."                    In re N.J.A.C. 5:96 
    II, supra
    , 221
    N.J. at 30 (emphasis added).
    We    therefore      reverse          the       order      and   remand   for   further
    proceedings.
    9                                   A-3323-15T1
    I.
    We begin by reviewing the pertinent principles of the Mount
    Laurel doctrine, the enactment of the FHA, the role of COAH, and
    the Supreme Court's decision in In re N.J.A.C. 5:96 II.5
    In    Mount    Laurel    I,   the        Supreme    Court     concluded      that
    developing municipalities must "presumptively make realistically
    possible an appropriate variety and choice of housing" through
    land use regulations.        
    Supra, 67 N.J. at 174
    .              The Court stated
    that such municipalities "cannot foreclose the opportunity of
    the classes of people mentioned for low[-] and moderate[-income]
    housing and in its regulations must affirmatively afford that
    opportunity, at least to the extent of the municipality's fair
    share of the present and prospective regional need."                      
    Ibid. The Court determined
    that land use regulations are encompassed in
    the State's police power, required such regulations to "promote
    public    health,   safety,    morals     or     the     general    welfare,"      and
    concluded "a zoning enactment which is contrary to the general
    welfare is invalid."      
    Id. at 175.
    Approximately eight years later, the Court returned to the
    issue.     In   Mount   Laurel     
    II, supra
    ,     
    92 N.J. 158
    ,   the     Court
    5
    In general, the Court determined COAH failed to promulgate
    valid   Third    Round   Rules,    concluded   that    exhausting
    administrative remedies before COAH was therefore no longer
    necessary, and established procedures for affordable housing
    matters to proceed before designated Mount Laurel judges.
    10                                 A-3323-15T1
    reaffirmed    the       doctrine    and    fashioned       a    judicial          remedy      for
    determining       a     municipality's           constitutional             obligation          to
    provide for low- and moderate-income housing.                         In re Adoption of
    N.J.A.C. 5:96 and 5:97 by the New Jersey Council on Affordable
    Hous., 
    215 N.J. 578
    , 587-89 (2013) (In re N.J.A.C. 5:96 I).
    Adding teeth to the doctrine, the Court sanctioned a builder's
    remedy,     which       permitted     builder-plaintiffs              to        sue    for    the
    opportunity       to    construct    housing       at    higher       densities          than   a
    municipality would allow.              
    Id. at 589.
                 In strengthening the
    Mount Laurel doctrine, the Court explained that the core of the
    doctrine was a municipality "would satisfy [its] constitutional
    obligation by affirmatively affording a realistic opportunity
    for   the   construction       of    its    fair       share    of        the    present      and
    prospective       regional     need       for    low[-]        and    moderate[-income]
    housing."     Mount Laurel 
    II, supra
    , 92 N.J. at 205.                                 The Court
    stated that a realistic opportunity depends on "whether there is
    in fact a likelihood — to the extent economic conditions allow —
    that the lower income housing will actually be constructed."
    
    Id. at 222.
               Although the Court devised a scheme to address
    resolution    of       litigation     in    this       field,        it    reiterated         its
    preference for legislative action.                      
    Id. at 212-13.
                   Two years
    later, and in the aftermath of AMG Realty Co. v. Township of
    Warren,     207     N.J.    Super.     388,      453     (Law     Div.          1984),       which
    11                                         A-3323-15T1
    articulated      a       method     for       calculating          affordable      housing
    obligations      that         substantially         impacted       the    likelihood      of
    whether lower income housing would actually be constructed, the
    Legislature enacted the FHA.
    The     FHA     codified           the        core    constitutional          holding
    undergirding the Mount Laurel obligation.                         In re N.J.A.C. 5:96
    
    I, supra
    , 215 N.J. at 584.                The FHA required "reasonable fair
    share   housing      guidelines         and    standards."           N.J.S.A.      52:27D-
    302(d).     The FHA created COAH, N.J.S.A. 52:27D-305, which was
    designed to provide an administrative alternative to litigating
    constitutional compliance in exclusionary zoning actions.                             In re
    N.J.A.C. 5:96 
    II, supra
    , 221 N.J. at 7-8, 11.
    COAH's primary responsibility was to assign and determine
    municipal    affordable         housing       obligations.          
    Id. at 7
      (citing
    N.J.S.A. 52:27D-305, -307).               The FHA required COAH to enact and
    thereafter      update         regulations          that     established        statewide
    affordable      housing        need;    to     assign       an     affordable      housing
    obligation to each municipality for its designated region; and
    to   identify      the     techniques         available      to     municipalities        in
    addressing the assigned obligation.                        
    Ibid. (citing N.J.S.A. 52:27D-307,
    -308).              The criteria and guidelines that the FHA
    directed     COAH        to     adopt     were       targeted       for     "[m]unicipal
    determination of its present and prospective fair share of the
    12                                   A-3323-15T1
    housing need in a given region which shall be computed for a
    [ten]-year period."          N.J.S.A. 52:27D-307(c)(1).                 The FHA defined
    prospective need:
    "Prospective need" means a projection of
    housing needs based on development and
    growth which is reasonably likely to occur
    in a region or a municipality, as the case
    may be, as a result of actual determination
    of   public   and   private   entities.  In
    determining prospective need, consideration
    shall be given to approvals of development
    applications, real property transfers and
    economic projections prepared by the State
    Planning Commission established by sections
    1 through 12 of P.L.1985, c.398 (C.52:18A-
    196 et seq.).
    [N.J.S.A. 52:27D-304(j).]
    Although   municipalities            were    free     to    resolve      constitutional
    Mount   Laurel      obligations       in     the     courts,      the    FHA    preferred
    resolution in an administrative forum.                     In re N.J.A.C. 5:96 
    II, supra
    , 221 N.J. at 4.
    The      FHA        encouraged     and        rewarded       voluntary      municipal
    compliance by (1) providing a period of immunity from civil
    lawsuits     to     towns     that     participated          in    the     process      for
    demonstrating          constitutional        compliance          (the    exhaustion-of-
    administrative-remedies             requirement);          and     (2)    providing       a
    presumption       of     validity     in     any     later       exclusionary      zoning
    litigation        for     municipalities           who     secured       from    COAH     a
    substantive       fair     housing     plan       certification.           
    Ibid. The 13 A-3323-15T1
    viability of these provisions was subject to COAH's updating of
    housing    obligations,        as     well       as     related       substantive       and
    procedural rules.      
    Ibid. In 1986, COAH
        began       adopting        rules       delineating       the
    affordable       housing    obligations          of     municipalities.           In     re
    Adoption   of     N.J.A.C.     5:94       and    5:95     by    the    N.J.     Coal.    on
    Affordable Hous., 
    390 N.J. Super. 1
    , 23 (App. Div.), certif.
    denied, 
    192 N.J. 71
    (2007) (In re N.J.A.C. 5:94).                         COAH adopted
    rules covering the periods of 1987 to 1993 — the First Round
    Rules — and 1993 to 1999 — the Second Round Rules.                                    In re
    N.J.A.C. 5:96 
    I, supra
    , 215 N.J. at 590.                       These rules generally
    utilized     a    methodology       for     calculating         affordable       housing
    obligations      employed    before       the    Legislature      enacted       the    FHA.
    
    Ibid. In the First
    Round Rules, COAH defined present need as "the
    total number of deficient housing units occupied by low[-] or
    moderate[-income]      households          as    of     July    1,     1987."         
    Ibid. (quoting N.J.A.C. 5:92-1.3).
              COAH    used    several       factors    to
    establish present need, such as "overcrowding, age of unit, and
    lack of plumbing, kitchen or heating facilities as indicators of
    dilapidated housing."         
    Id. at 590-91.
    The    First     Round     Rules      also        incorporated      the     statutory
    definition of prospective need as "a projection of low[-] and
    14                                    A-3323-15T1
    moderate[-income] housing needs based on development and growth
    . . . reasonably likely to occur in a region or a municipality."
    
    Id. at 591
        (quoting          N.J.A.C.       5:92-1.3).             COAH    analyzed
    statistics to project forward the number of "'low- and moderate-
    income       households'      that       would       form    between     1987    and       1993."
    
    Ibid. (quoting N.J.A.C. 5:92,
          Appendix     A    at    92-49).         In
    determining         prospective         need,    COAH       considered    such       things   as
    municipalities'            "approvals      of    development          applications,         real
    property      transfers       and       economic      projections        prepared      by     the
    State Planning Commission."                
    Ibid. (quoting N.J.A.C. 5:92-1.3).
    For      the     Second           Round    Rules,        COAH      used        the    same
    methodologies employed in the First Round Rules.                                
    Id. at 592.
    COAH also adopted additional regulations granting credits and
    various       adjustments          to     reduce       municipalities'          fair        share
    figures.       
    Ibid. (summarizing the adopted
    regulations granting
    credits and adjustments).                 Various legal challenges to the First
    and Second Round Rules failed.                   
    Ibid. Essentially, the methodology
    of allocating municipalities'
    affordable      housing       obligations            largely    followed       the    remedial
    approaches established by Mount Laurel II and AMG Realty.                                     
    Id. at 593.
          COAH first calculated the need for affordable housing
    in    each     of    the     State's       regions,          then   allocated         to     each
    municipality         its    fair    share       of    the     present    and     prospective
    15                                     A-3323-15T1
    regional      need.         
    Ibid. A municipality would
        be     assigned       a
    proportionate fair share of the region's housing need based on
    economic projections and its capacity to accommodate affordable
    housing.       
    Ibid. A municipality would
    subject itself to the
    possibility     of     defending       a   builder's     remedy     challenge       if    it
    failed   to    create       a   realistic      opportunity    for    satisfying          its
    assigned share.         
    Ibid. Although the Second
       Round     Rules   expired     in     1999,    COAH
    belatedly promulgated its first iteration of the Third Round
    Rules in 2004.6         
    Ibid. The rule proposal
    published in the New
    Jersey Register explained that a municipality's fair share for
    the   period     from        1987     through    January     1,     2014,    would        be
    calculated using three criteria:
    (1) a municipality's "rehabilitation share"
    based on the condition of housing revealed
    in the data gathered for the 2000 Census,
    previously    known  as   a   municipality's
    indigenous   need;   (2)   a  municipality's
    unsatisfied prior round obligation (1987
    through 1999), satisfaction of which will be
    governed by the second round rules; and (3)
    a municipality's "growth share" based on
    housing need generated by statewide job
    growth and residential growth from 1999
    through 2014.
    6
    We characterized this delay as "dramatic," "inexplicable,"
    and frustrating the public policies embodied by the Mount Laurel
    line of cases.   In re Six Month Extension of N.J.A.C. 5:91 et
    seq., 
    372 N.J. Super. 61

    [Id. at 593-94 (quoting In re N.J.A.C. 
    5:94, supra
    , 390 N.J. Super. at 27).]
    During     the   gap   period,   we   considered   challenges   to    the
    validity of the Third Round Rules and remanded the matter to
    COAH on two occasions with instructions to adopt revised Third
    Round Rules.
    Our first remand to COAH with instructions to adopt revised
    rules occurred in 2007.        In re N.J.A.C. 
    5:94, supra
    , 390 N.J.
    Super. at 47.    At that time, we sustained some but rejected many
    of the challenges to the first iteration of the Third Round
    Rules.   Importantly, Judge Mary Catherine Cuff, writing for the
    panel, noted that "municipalities are responsible for fulfilling
    their prior round obligation."        
    Id. at 28
    (citing N.J.A.C. 5:94-
    2.1(a)(2)).
    Judge      Cuff's     opinion      rejected
    [7]
    appellants'         arguments      that      the
    "rehabilitation share" of a municipality's
    affordable    housing   obligation,   sometimes
    also referred to as present need, should
    include "cost burdened" low- and moderate-
    income households that reside in standard
    housing and households that lack permanent
    housing or live in overcrowded housing; that
    COAH's     methodology      for     identifying
    substandard    housing   was   "arbitrary    and
    unreasonable"; that the [T]hird [R]ound

    The appellants challenged the validity of COAH's substantive
    rules for the third round that calculated affordable housing
    needs from 1999 to 2014, as well as the validity of several
    regulations.
    17                             A-3323-15T1
    [R]ules improperly eliminated the part of
    the first and second round methodologies
    that required reallocation of excess present
    need in poor urban municipalities to other
    municipalities in the region; that the use
    of   regional   contribution   agreements   to
    satisfy part of a municipality's affordable
    housing   obligations   violates   the   Mount
    Laurel   doctrine   and   federal  and   state
    statutory provisions; that the allowance of
    bonus credits towards satisfaction of a
    municipality's        affordable       housing
    obligations unconstitutionally dilutes those
    obligations; and that the rule relating to
    vacant land adjustments violates the Mount
    Laurel doctrine and the FHA.
    However,       Judge     Cuff's     opinion
    invalidated    the    parts  of    the  original
    [T]hird    [R]ound     [R]ules    that   reduced
    statewide and regional affordable housing
    need based on "filtering"; adopted a growth
    share    approach       for     determining    a
    municipality's fair share of prospective
    needs for affordable housing and excluded
    job growth resulting from rehabilitation and
    redevelopment in determining job growth;
    compelled developers to construct affordable
    housing without any compensating benefits;
    authorized    a    municipality     to  give   a
    developer the option of payment of a fee in
    lieu of constructing affordable housing, but
    provided no standards for setting those
    fees; and authorized a municipality to
    restrict up to 50% of newly constructed
    affordable    housing     to   households   with
    residents aged fifty-five or over.

    18                           A-3323-15T1
    In   2010,   Judge      Stephen     Skillman,       also     writing      for     a
    different     panel,    invalidated        a    substantial        portion      of     the
    revised     Third      Round     Rules,        including     the     growth          share
    methodology used by COAH, 
    id. at 511-12;
    regulations concerning
    the preparation of fair share plans, 
    id. at 487-88;
    presumptive
    incentives    embodied      in   the     regulations,       
    id. at 488-93;
          and
    regulations concerning rental credits, 
    id. at 493-95.
    Judge Skillman upheld several of the regulations, however,
    such as the elimination of reallocated present need, 
    id. at 500-
    02     (reasoning   COAH       possessed       the   authority       to    focus        on
    municipalities' own obligations, see N.J.A.C. 5:97-2.4, rather
    than     reallocating       excess      present      need     away       from        those
    overburdened with substantial housing); and COAH's decision to
    use the prior round obligations without updating the obligations
    based on actual household growth, 
    id. at 498-500.
                          Consequently,
    we redirected COAH to adopt new rules.
    During the gap period, the New Jersey Supreme Court also
    invalidated revised Third Round Rules and issued deadlines for
    COAH to adopt new regulations.                 In re N.J.A.C. 5:96 
    I, supra
    ,
    215 N.J. at 619-20.            Acknowledging the FHA had set a course
    tracking     the    Mount      Laurel     II     allocation       methodology          for
    satisfaction of present and prospective need, the Court remarked
    that "the Third Round Rules' validity hinges in whether they are
    19                                    A-3323-15T1
    consistent with the FHA."       
    Id. at 612-17.
               In 2014, the Court
    granted COAH an additional five months to adopt new rules.                         In
    re N.J.A.C. 5:96 and 5:97, 
    220 N.J. 355
    , 355-56 (2014).
    COAH failed to meet the extension deadline, which led the
    Court to grant Fair Share's motion in aid of litigants' rights
    in In re N.J.A.C. 5:96 
    II, supra
    , 221 N.J. at 5-6.                    The Court
    recognized the administrative process had become nonfunctioning.
    
    Id. at 5.
       As   a   result,    the      FHA's    exhaustion-of-remedies
    requirement had been rendered futile.                 
    Ibid. Therefore, there no
    longer existed a legitimate basis to block access to the
    courts     for    resolution        of        municipal       compliance       with
    constitutional    affordable   housing.           
    Ibid. Recognizing there existed
    various stages of municipal preparation during the gap
    period,    the   Court    established         a   transitional     process       for
    exclusionary zoning actions to proceed.                
    Ibid. The Court also
    emphasized:
    Importantly, nothing herein should be
    understood to prevent COAH from fulfilling
    its     statutory     mission      to     adopt
    constitutional      rules       to       govern
    municipalities' Third Round obligations in
    compliance with the FHA.      Nor should the
    action taken by this Court, in the face of
    COAH's failure to fulfill its statutory
    mission,   be   regarded   as   impeding    the
    Legislature   from   considering    alternative
    statutory remedies to the present FHA.
    [Id. at 6 (citation omitted).]
    20                                A-3323-15T1
    The Court developed a process which tracked the processes
    provided for in the FHA.           
    Id. at 29.
           It did so to facilitate a
    return to agency proceedings in the event COAH promulgated new
    Third   Round    Rules.     
    Ibid. In establishing the
      process   for
    exclusionary zoning actions to proceed, the Court stated:
    [I]t is not this Court's province to create
    an     alternate     form    of     statewide
    administrative decision maker for unresolved
    policy details of replacement Third Round
    Rules . . . .     The courts that will hear
    such declaratory judgment applications or
    constitutional compliance challenges will
    judge them on the merits of the records
    developed in individual actions before the
    courts.   However, certain guidelines can be
    gleaned from the past and can provide
    assistance to the designated Mount Laurel
    judges in the vicinages.
    [Id. at 29-30 (emphasis added).]
    The   Supreme    Court    established       procedures    for      addressing   two
    classes of municipalities that were stranded by COAH's inability
    to adopt valid Third Round Rules.                
    Id. at 24-29
    (outlining the
    procedures for municipalities that "made the effort to comply
    promptly with the Third Round Rules and . . . received a grant
    of    substantive    certification,"           and   municipalities      that   had
    "participating" status with COAH).
    Although presented with numerous opportunities to do so, at
    no    point   did   the   Court,    the     Legislature,      or   the   Appellate
    Division impose an additional separate gap-period obligation.
    21                              A-3323-15T1
    Rather, in establishing a municipality's fair share affordable
    housing obligation, the focus consistently remained on present
    and prospective housing need.
    II.
    We    now    turn   to   the   proceedings      conducted      by   the     judge
    leading to his ruling that municipalities are "constitutionally
    mandated" to address the gap period as a "separate and discrete"
    component of their fair share Mount Laurel obligation.
    Following the procedures established by the Court in In re
    N.J.A.C. 5:96 
    II, supra
    , 221 N.J. at 21-34, several Ocean County
    municipalities       filed    declaratory      judgment       actions         seeking
    resolution      of   their   Mount   Laurel        obligations.         The     judge
    undertook preliminarily to determine the present and prospective
    affordable housing needs of the municipalities.                    To reach this
    determination, the court reviewed several expert reports that
    expressed differing opinions on the subject.
    The    judge     appointed     Richard    B.    Reading   as    the       Special
    Regional Master, who was to "assist the court in making the
    preliminary determination envisioned by the Supreme Court of the
    present and prospective needs."              The judge allowed submissions
    of expert reports and expected to conduct a plenary hearing at
    which the court would address the conflicting expert opinions as
    22                                  A-3323-15T1
    to   the    methodology      for     calculating     the   municipalities'
    affordable housing obligations.
    On    December    29,   2015,   Mr.   Reading   submitted   a    report
    entitled     "COAH's      Un[-]adopted      Third     Round   Methodology
    Calculation of 'Gap' Period Housing Needs."           In this report, Mr.
    Reading listed these questions the judge identified in a case
    management order:
    1) Is the methodology provided in Appendix
    D[8] of the current iteration of the [un-
    adopted] Third Round Rules an appropriate
    and correct methodology?
    2) Do the trial courts have the authority to
    require a municipality to address the . . .
    'gap' obligation component as part of a
    municipality's prior obligation?[9]
    Mr. Reading concluded that the "methodology in Appendix D
    [did] not follow the methodologies utilized in the calculation
    of affordable housing needs employed in the [p]rior [r]ounds."
    He stated that "[a] review of the history of Mount Laurel did
    not disclose a methodology that expanded the calculation of fair
    share beyond [p]resent and [p]rospective [n]eed."             He remarked
    that Sections 304 and 307 of the FHA established "prospective
    8
    Mr. Reading identified the un-adopted Third Round Rules as
    N.J.A.C. 5:99, Appendix D.
    9
    The third question, "[w]hat is the proper allocation of the
    1000 unit cap . . . [and] how should the gap be applied to any
    'gap period' need if one exists," is not at issue.
    23                             A-3323-15T1
    need as a period of ten years and includes a projection of
    housing   needs   based    upon   development         and   growth    that    is
    reasonably likely to occur."         He determined that the "inclusion
    of the prior [gap period] within prospective need is contrary to
    prior round methodologies, the language of the FHA and history
    of determining affordable housing needs."               As to "identifying
    and   quantifying"   the   housing     need   from    the   gap   period,    Mr.
    Reading stated:
    [The unmet need arising during the gap
    period] was discussed in terms of the
    disposition of [low- and moderate-income]
    housing needs that existed . . . in the
    past.    These households would be partially
    included by the [low- and moderate-income]
    households in over[]crowded or deficient
    housing units that are encompassed in the
    new calculation of [p]resent [n]eed.     Those
    [low- and moderate-income] households that
    have occupied sound (non-deficient) housing
    units are already [in] housing and would not
    represent an identifiable need.     Some [low-
    and    moderate-income]    households   formed
    during    the  gap   period   may   no  longer
    represent an affordable housing need due to
    a   variety   of   reasons   including  death,
    changes in income, increase or decrease in
    household size, retirement and/or relocation
    outside of New Jersey. . . .       Although it
    may be possible to generate an estimate of
    such a residual need, such an estimate would
    be speculative.
    [(Emphasis added).]
    Mr.   Reading   stated   "there   is    a   uniform    consensus     among   the
    interested parties that the methodology provided in Appendix D
    24                              A-3323-15T1
    is   not    an     appropriate       and      correct      methodology         for       the
    calculation       of    affordable      housing     [gap-period]        needs."            He
    explained further that even though there existed this consensus
    rejecting     COAH's          un-adopted      methodology,        "an        appropriate
    methodology for determining an affordable housing need [during
    the 1999-2015 'gap period' was] not . . . presented."10
    On February 17, 2016, Mr. Reading issued a report entitled
    "Bridging   the        Gap,   1999-2015     'Gap'   Period    Affordable           Housing
    Needs."      In    this       report,   Mr.      Reading    responded         to    expert
    opinions contained in reports submitted by Dr. David N. Kinsey,
    on behalf of Fair Share, and Econsult.                     After reviewing these
    opinions, Mr. Reading recommended to the judge that he "consider
    the inclusion of the [g]ap[-p]eriod, calculated distinctly and
    separately from [p]resent and [p]rospective [n]eed," which is a
    markedly    different          recommendation       than     what       he    expressed
    previously.
    Mr. Reading stated Dr. Kinsey provided two alternatives for
    calculating      affordable       housing       needs   arising     during         the   gap
    10
    Mr. Reading acknowledged, in a later report, Fair Share's
    contention that the gap-period should be included "within the
    extended 1999-2025 [p]rospective [n]eed."    He also considered
    the NJLM and a report prepared by Econsult Solutions (Econsult),
    on behalf of a consortium of municipalities, stating there is no
    basis for "retrospective analysis of housing need, which has
    always been based on 'present and prospective need.'" (Emphasis
    added).
    25                                      A-3323-15T1
    period:    calculating    the      entire      period    from    1999-2025     as   a
    prospective need, without a separation of the gap period and
    prospective     need    projection;         and    replicating      COAH's     1994
    recalculation    of    the   1987-1993         housing    need     (although    Mr.
    Reading recognized that such a recalculation was done to adjust
    a prior (1987-1993) obligation, not to establish a methodology
    for addressing a lapse in assigned obligations).
    Econsult      provided         a     comprehensive          methodology     for
    establishing    the    1987-1999       prior    round   obligations,    the    2015
    present need, and the 2015-2025 prospective need.                      Econsult's
    methodology did not include calculations for the gap period.
    Econsult critiqued Dr. Kinsey's two alternatives.                      As to the
    first   alternative,     Econsult       maintained      essentially    that    gap-
    period low- and moderate-income households living in deficient
    housing would be encompassed in present need, while low- and
    moderate-income households living in adequate housing would not
    represent an identifiable need.                As to the second alternative,
    Econsult    reiterated       its       positon    that     present     need     and
    prospective need combine to represent the entire fair share need
    of, in its opinion, Dr. Kinsey's calculation of retrospective or
    gap-period needs.
    In his February 17, 2016 report, Mr. Reading stated that
    the gap-period issue had become a legal issue.                   He acknowledged
    26                              A-3323-15T1
    that all parties agreed low- and moderate-income households were
    formed during the gap period and have secured housing, some of
    which were deficient or overcrowded, which would be reflected in
    present need.    As to the proper methodology for calculating
    municipalities' affordable housing need arising during the gap
    period, he concluded:
    The calculation of the current needs of the
    affordable hous[ing] formed during the [gap
    period] is not a process that is [e]mbedded
    in the [p]rior [r]ound methodology, [and] is
    not projected ([p]rospective) need, but
    should be undertaken as a separate and
    discrete component of affordable housing
    need.   Prior submissions provided by [Fair
    Share] and Econsult on December 8, 2015
    contended that the calculation for the [g]ap
    [p]eriod   affordable  housing   needs   were
    unnecessary because they were properly a
    part of the 1999-2025 [p]rospective [n]eed
    . . . or were unnecessary altogether because
    the FHA does not make any provision for a
    retrospective need . . . .
    . . . .
    Assertions that a determination of [g]ap
    [p]eriod affordable housing need cannot be
    reduced    to    a    precise    mathematical
    calculation devoid of all assumptions and
    estimates is not distinctly different than
    the preparation of estimates for . . .
    [p]resent . . . and [p]rospective [n]eed[,]
    [which]   are   likewise    predicated   upon
    estimates [and] . . . would . . . be no more
    impaired.
    As a result, Mr. Reading recommended the court should sanction a
    completely new and different methodology than that used during
    27                        A-3323-15T1
    the   first    two    rounds    or   in    the    FHA,   one   that     "should     be
    calculated as [a] separate and discrete component of affordable
    housing   need     utilizing     data     and    procedures    appropriate     to   a
    prior,    rather      than     future     period."       In    other    words,      he
    recommended a methodology that retrospectively calculated gap-
    period housing need, rather than, as he stated in his December
    29,   2015    report,    the     unmet     gap-period    housing       needs   being
    included in "the new calculation of present need."
    The next day, on February 18, 2016, the court adopted Mr.
    Reading's new recommendation and issued its opinion.                     As to the
    gap period, the court stated:
    The    court    finds   municipalities    are
    constitutionally mandated to address [the
    gap-period] obligation.    This "gap period"
    need is to be calculated as a separate and
    discrete component of a municipality's fair
    share    obligation.      This   component[,]
    together with a municipality's unmet prior
    round obligations [from] 1987 to 1999[,] and
    its present need and prospective need[,]
    shall comprise its "fair share" affordable
    housing obligation for the third [round]
    housing cycle.
    . . . .
    [I]t is ironic that both parties (or
    interests) appearing in [a] 2004 Appellate
    Division case are now advancing arguments
    before this court [that] they vehemently
    opposed in [In re Six Month].
    . . . .
    28                               A-3323-15T1
    Even   if    the    municipalities  were
    [therefore]    not    [now]    estopped  from
    advancing their position[,] and despite
    their efforts here to distinguish . . . [In
    re Six Month] . . . the court finds the
    underlying principles in [In re Six Month]
    . . . are the same as the matter here.
    [(Emphasis added).]
    III.
    On appeal, the entities urging us to reverse the order
    argue that the judge erroneously imposed a new "separate and
    discrete" component of a municipality's fair share affordable
    housing obligation during the gap period.                     They contend the
    judge erred by: (1) failing to apply the plain language of the
    FHA; (2) ignoring the guidelines and principles established by
    In re N.J.A.C. 5:96 II; (3) applying the doctrine of judicial
    estoppel; and (4) acting as a replacement agency for COAH by
    resolving unresolved policy details of replacement Third Round
    Rules.
    They     assert     that   a   municipality's     fair    share   affordable
    housing obligation for the third-round cycle is comprised of:
    (1) the unmet prior round (before 1999) obligations; (2) present
    need; and (3) prospective need.              They maintain, as Mr. Reading
    expressed    in   his    December    29,     2015   report,    that   gap-period
    affordable    housing      needs     would     be   captured     in   a    town's
    calculation of its present need.             They emphasize that imposing a
    retrospective     gap-period       obligation       does   not   allow     for     a
    29                                 A-3323-15T1
    realistic       opportunity       that        the     lower       income       housing      will
    actually be constructed.
    The entities urging us to affirm the order under review
    argue     primarily       that:     (1)        a     municipality's            prior        round
    unfulfilled      affordable       housing           obligations         includes      the    gap
    period;    (2)    the     FHA,    as     determined          by    COAH,       provides      for
    cumulative and uninterrupted calculations of prospective need;
    (3)    COAH's    interpretation          of    the     FHA    providing         for    gapless
    affordable      housing    need     is    reasonable;             and    (4)    the    judge's
    ruling complies with the FHA and In re N.J.A.C. 5:96 II.
    Our standard of review is well settled.                          The sole question
    on    appeal,    whether    a     retrospective          gap-period         obligation         is
    authorized by the core principles of the Mount Laurel doctrine,
    as codified in the FHA, and In re N.J.A.C. 5:96 II, is a legal
    issue not entitled to any special deference.                            Manalapan Realty,
    L.P. v. Twp. Comm. of Manalapan, 
    140 N.J. 366
    , 378 (1995).
    IV.
    Applying the plain language of the FHA, the guidelines and
    principles established by In re N.J.A.C. 5:96 II, and respecting
    the separation of powers doctrine,11 we conclude that the judge
    11
    The framers of the New Jersey Constitution articulated the
    separation of powers doctrine expressing that
    (continued)
    30                                       A-3323-15T1
    erroneously imposed a requirement that a municipality undertake
    a   new,   "separate   and   discrete"    gap-period   calculation    –    in
    addition    to   unmet   prior    round    obligations,    present,       and
    prospective needs – to establish a municipality's fair share
    affordable housing obligation.           We also reject the contention
    that judicial estoppel precludes reversal of the February 18,
    2016 order under review.
    A.
    We start with the plain language of the FHA.         Our paramount
    goal in interpreting a statute is to ascertain the Legislature's
    intent, and "generally[] the best indicator of that intent is
    the statutory language."       DiProspero v. Penn, 
    183 N.J. 477
    , 492
    (2005) (citation omitted).       When interpreting a statute, we give
    words "their ordinary meaning and significance."              Tumpson v.
    Farina, 
    218 N.J. 450
    , 467 (2014) (quoting 
    DiProspero, supra
    , 183
    N.J. at 492).    Only when the statutory language is ambiguous and
    yields more than one plausible interpretation do we turn to
    (continued)
    [t]he powers of the government shall be
    divided among three distinct branches, the
    legislative, executive, and judicial. No
    person   or    persons  belonging   to   or
    constituting one branch shall exercise any
    of the powers properly belonging to either
    of the others, except as expressly provided
    in this Constitution.

    extrinsic      sources,          such    as    legislative      history.         
    DiProspero, supra
    , 183 N.J. at 492-93.                 Here, there is no ambiguity.
    The     plain        language      of    the    FHA     refers    to    present    and
    prospective need.                Responding to the significantly high fair
    share     obligations            in     the     aftermath       of     AMG     Realty,    the
    Legislature enacted the FHA, finding that one of the "essential
    ingredients"           to       its     response       was    "the      establishment      of
    reasonable           fair    share       housing       guidelines        and     standards."
    N.J.S.A. 52:27D-302(d).                  Consequently, the Legislature focused
    on    present       and     prospective        need,    N.J.S.A.       52:27D-307(b),     and
    charged COAH to adopt guidelines for "[m]unicipal determination
    of its present and prospective fair share of the housing need in
    a given region which shall be computed for a 10-year period,"
    N.J.S.A. 52:27D-307(c)(1) (emphasis added).
    The FHA defines prospective need not by looking backwards,
    but     rather        as    a     "projection         of     housing     needs    based    on
    development and growth which is reasonably likely to occur in a
    region    or     a    municipality."            N.J.S.A.       52:27D-304(j)       (emphasis
    added).        In determining prospective need, COAH considered such
    things         as         municipalities'             "approvals        of       development
    applications, real property transfers and economic projections
    prepared by the State Planning Commission."                          In re N.J.A.C. 5:96
    
    I, supra
    , 215 N.J. at 591 (quoting N.J.A.C. 5:92-1.3).
    32                                  A-3323-15T1
    The FHA did not define present need, but in the valid First
    Round Rules, COAH defined present need as "the total number of
    deficient housing units occupied by low[-] or moderate[-income]
    households."       
    Id. at 590
    (quoting N.J.A.C. 5:92-1.3).                   COAH used
    several      factors        to      establish       present        need,     such       as
    "overcrowding, age of unit, and lack of plumbing, kitchen or
    heating facilities as indicators of dilapidated housing."                              
    Id. at 590-91.
    The    judge     noted        that    COAH,     in    each     of    its      three
    unsuccessful       attempts         to     promulgate       Third     Round       Rules,
    referenced    the     gap     period,      albeit    with   different      unapproved
    methodologies.        Although the judge acknowledged COAH's reference
    to the gap period during its three iterations of the un-adopted
    Third Round Rules, we note that an agency is not at liberty to
    impose additional requirements onto a statute that do not exist
    on its face.       See In re N.J.A.C. 5:96 
    I, supra
    , 215 N.J. at 614-
    15 (invalidating the growth share methodology in the Third Round
    Rules and explaining that COAH may not enact regulations plainly

    sustenance to the enactment").                 To the extent COAH interpreted
    the FHA to include a requirement beyond present and prospective
    need and fulfilling prior round obligations, we conclude such an
    interpretation is "at odds with the plain meaning of the [FHA]."
    
    Oberhand, supra
    , 193 N.J. at 568.               The same proscription applies
    to the courts.
    Importantly,       during    the    sixteen-year     gap     period,     the
    Legislature amended the FHA twelve times.                It did not amend the
    FHA, however, to require a retrospective determination of gap-
    period obligations.         Failure to so amend the FHA does not amount
    to     Legislative      authorization     to     retroactively    adopt    a    new
    methodology for calculating affordable housing gap-period needs,
    even     if    COAH's     un-adopted      Third     Round   Rules    sought      to
    encapsulate the gap period.          See GE Solid 
    State, supra
    , 132 N.J.
    at 312-13 (rejecting that the Legislature's failure to interfere
    with an administrative interpretation is proof that the agency's
    34                              A-3323-15T1
    interpretation conforms with legislative intent or establishes
    legislative acquiescence); see also Airwork Serv. Div., Div. of
    Pac. Airmotive Corp. v. Dir., Div. of Taxation, 
    97 N.J. 290
    , 296
    (1984)    (explaining          that    administrative             acquiescence        is     only
    relevant      when      "the    Legislature's          intent      cannot        otherwise     be
    determined by a critical examination of the purposes, policies,
    and language of the enactment" (emphasis added)).
    Fair        Share,      supported          by        Dr.        Kinsey,     interprets
    "prospective need" to mean that a town is required to look at
    affordable housing needs prospectively starting from 1999, in
    addition      to    a   separate      ten-year         prospective        need    calculation
    from the present.              In other words, Fair Share argues a town's
    "prospective need" would cover a period of twenty-seven years,
    from     1999      to   ten    years       from      now.         We    conclude      such     an
    interpretation is clearly at odds with the FHA's unambiguous
    definition of prospective need.                      As it is defined in the FHA,
    prospective        need     refers    to    a     "projection"          of   growth    in     the
    future,       namely      a    "projection           of     housing       needs     based      on
    development and growth which is reasonably likely to occur in a
    region or a municipality."                 By its nature, it does not involve
    retrospectively including a gap-period calculation.
    In sum, to impose a gap-period requirement would inevitably
    add a new requirement not previously recognized under the FHA.
    35                                    A-3323-15T1
    The     Supreme        Court    has       cautioned          courts    not     to   become     a
    replacement agency for COAH in promulgating substantive rules.
    Rather, based on COAH's inaction, courts must work within the
    provisions of the FHA and should employ the first and second
    round    methodologies          to     determine        a     municipality's        compliance
    with its Mount Laurel obligations.                            Until COAH adopts Third
    Round Rules, or until the Legislature acts, the courts may not
    act as a legislature by imposing new, substantive obligations
    not recognized under the FHA.
    B.
    Next, the judge did not follow the guidelines established
    by the Court in In re N.J.A.C. 5:96 II.                               We will address the
    relief     requested       in     In       re    N.J.A.C.       5:96     II,    the    Court's
    response, and then our application of the guidelines to the
    judge's ruling.
    (i)
    In In re N.J.A.C. 5:96 II, Fair Share, the NJBA, the NJLM,
    and various towns expressed their respective positions as to the
    guidance        they     believed         the        Court    should     provide      to     the
    designated       Mount     Laurel         judges.        We    briefly    summarize        these
    competing positions to emphasize the Court's unwillingness to
    decide    "unresolved          policy      details       of    replacement      Third      Round
    Rules"     or     to     become       a    "replacement          agency      for    COAH"     by
    36                                   A-3323-15T1
    essentially   endorsing   a   new   methodology    for   separately     and
    discretely calculating affordable housing needs during the gap
    period.
    [Fair Share] ask[ed] that the second-round
    methodology, with limited modifications, be
    directed    for    use    in    such   [remand]
    proceedings    and   that    newly   authorized
    judicial actions proceed expeditiously and
    on    a    notice-and-opportunity-to-be-heard
    basis.
    . . . .
    . . . [NJBA] contend[ed] that the
    administrative   stalemate    ha[d]   permitted
    municipalities to "shelter themselves" from
    suit   under   COAH's   jurisdiction    without
    providing any additional affordable housing
    in years. They urge[d] the Court to fashion
    relief   that   [would]   require   courts   to
    examine what towns have done to date in
    attempting to satisfy their constitutional
    obligations.
    . . . .
    [Various   towns]   contend[ed]   that   trial
    courts would be tasked with determining
    whether    a   municipality's    fair    share
    allocation    will    be    "cumulative"    or
    applicable only to one compliance period.
    The[y] also contend[ed] that adjudicating
    such Mount Laurel matters would require
    courts to confront the myriad differences
    between the methodologies utilized in the
    prior rounds and those contained in the
    various iterations of COAH's Third Round
    Rules.
    . . . .
    [NJLM]    argue[d]          that     the     314
    municipalities   [which        had    submitted    to
    37                            A-3323-15T1
    COAH's substantive certification under the
    earlier   Third   Round   Rules]  should   not
    forfeit    their    protection   from    suit.
    According   to   NJLM,   exclusionary   zoning
    litigation would punish the municipalities,
    which [were] not responsible for COAH's most
    recent failure to adopt compliant Third
    Round Rules.
    Notably, NJLM propose[d] an alternate
    solution, arguing that COAH ha[d] expended
    significant resources in developing the most
    recent proposed regulations, which efforts
    should not be wasted. NJLM suggest[ed] that
    the Court appoint "a former high-ranking
    policy-making official" to recruit three
    "professional    planners"   to   assist   in
    reviewing COAH's proposed Third Round Rules,
    the 3000 public comments, and any responses
    prepared by COAH's staff.     NJLM propose[d]
    that this Court authorize those planners to
    revise the proposed Third Round Rules for
    review by the Court-selected "policy-making
    official."      If   the   policy  maker   is
    satisfied, NJLM further propose[d] that he
    or she would present the revised regulations
    to this Court for approval, and for entry of
    an order directing COAH to adopt the Third
    Round Rules in that form.
    [In re N.J.A.C. 5:96 
    II, supra
    , 221 N.J. at
    12-16 (emphasis added).]
    The Court responded to Fair Share's plea for guidance and, in
    light of the various stages of municipal preparation that had
    existed   "as    a     result   of   the   long     period        of    uncertainty
    attributable to COAH's failure to promulgate Third Round Rules,"
    the   Court     devised    a    transitional      process        before     allowing
    exclusionary     zoning    actions    to   proceed.         
    Id. at 20.
         In
    articulating     the   transitional    process,     and     by    expressing       the
    38                                     A-3323-15T1
    concomitant "guidelines . . . gleaned from the past [that] can
    provide assistance to the designated Mount Laurel judges," 
    id. at 29-30,
    the Supreme Court did not include a new methodology
    for calculating additional housing obligations during the gap
    period.    In    our    view,   consideration       of   imposing   such     a   new
    policy — that essentially addresses "unresolved policy details
    of replacement Third Round Rules" — is best left to the other
    two branches, where important public policy considerations can
    be fairly, fully, and openly debated.
    (ii)
    We now address the actual guidelines and principles listed
    by the Court for use by designated Mount Laurel judges handling
    declaratory     judgment     applications    on     constitutional-compliance
    applications.          In   enumerating     these    guidelines,     the      Court
    reiterated it did not intend to punish the towns that were "in a
    position of unfortunate uncertainty due to COAH's failure to
    maintain the viability of the administrative remedy."                       
    Id. at 23.
      Instead, the Court explained:
    Our goal is to establish an avenue by which
    towns can demonstrate their constitutional
    compliance [i.e., present and prospective
    obligations]    to   the    courts    through
    submission of a housing plan and use of
    processes,   where  appropriate,   that   are
    similar to those which would have been
    available through COAH for the achievement
    of    substantive    certification.     Those
    processes include conciliation, mediation,
    39                                   A-3323-15T1
    and the use, when necessary, of special
    masters.   The end result of the processes
    employed by the courts is to achieve
    adoption of a municipal housing element and
    implementing   ordinances   deemed  to   be
    presumptively valid if thereafter subjected
    to challenge by third parties.
    [Id. at 23-24 (emphasis added).]
    The Court then identified specific procedures, guidelines, and
    principles.
    In   In    re    N.J.A.C.         5:96    II,    the     Court    reasserted      that
    "previous methodologies employed in the First and Second Round
    Rules   should      be    used       to   establish        present    and   prospective
    statewide and regional affordable housing need."                              
    Id. at 30
    (emphasis added).          As a result, municipalities were required to
    demonstrate    to        the   court      computations        of    housing    need    and
    municipal   obligations          "based      on    those     methodologies."       
    Ibid. (emphasis added). The
       Court       reminded    the    designated       Mount
    Laurel judges they had the same discretion that COAH enjoyed
    when "assessing a town's plan, if persuaded that the techniques
    proposed by a town will promote for that municipality and region
    the constitutional goal of creating the realistic opportunity
    for producing its fair share of the present and prospective need
    for low- and moderate-income housing."                     
    Ibid. (emphasis added). Importantly,
    the Court did not eradicate the prior round
    obligations.     
    Ibid. Instead, the Court
    stated "municipalities
    40                                A-3323-15T1
    are   expected     to    fulfill        those       obligations.        As   such,     prior
    unfulfilled housing obligations should be the starting point for
    a determination of a municipality's fair share responsibility."
    
    Ibid. In reaching this
    conclusion, the Court cited Judge Cuff's
    recognition that "municipalities are responsible for fulfilling
    their prior round obligation," In re N.J.A.C. 
    5:94, supra
    , 390
    N.J. Super. at 28, and Judge Skillman's approval, as a starting
    point, for the imposition of "the same prior round obligations
    [COAH] had established as the second round obligations in 1993,"
    In re N.J.A.C. 
    5:96, supra
    , 416 N.J. Super. at 498-500.
    Fulfilling    prior   round         obligations,      as   described       by   the
    Court and in our 2007 and 2010 remand opinions, is decidedly
    different      than     imposing    a     new,       retrospective,      "separate        and
    discrete"       methodology        for        establishing       affordable         housing
    obligations during the gap period.                        A court-imposed "separate
    and discrete" retrospective gap-period calculation, on top of a
    town's       existing     and    present            and    prospective       fair      share
    affordable housing obligations, would amount to the Court acting
    as    a    replacement    agency        for    COAH,      and   would   contravene        the
    Court's       unwillingness        to     decide          unresolved     policy      issues
    relating to replacement Third Round Rules.
    In addition to this assistance, the Court identified other
    principles that Mount Laurel designated judges should follow,
    41                                   A-3323-15T1
    such as: our prior treatment of reallocation of present need 12;
    bonus credits; cost-burdened poor; and the reduction of fewer
    surrogate indicators.       In re N.J.A.C. 5:96 
    II, supra
    , 221 N.J.
    at 30-33.     The Court emphasized that the courts should "employ
    flexibility in assessing a town's compliance and should exercise
    caution to avoid sanctioning any expressly disapproved practices
    from     COAH's   invalidated     Third       Round    Rules."    
    Id. at 33.
    Finally, the Court reiterated its "hope that an administrative
    remedy     will   again    become    an       option    for   those     proactive
    municipalities      that   wish     to    use    such    means   to    obtain     a
    determination of their housing obligations and the manner in
    which those obligations can be satisfied."                
    Id. at 34
    (emphasis
    added).
    (iii)
    Here, the judge's ruling respectfully did not comport with
    In re N.J.A.C. 5:96 II.           The Court repeated its instructions
    that "previous methodologies employed in the First and Second
    Round Rules should be used to establish present and prospective
    statewide and regional affordable housing need."                      
    Id. at 30
    .
    Further, it stated that "[t]he parties should demonstrate to the
    12
    "The [S]econd [R]ound [R]ules define[d] reallocated present
    need as 'the share of excess deterioration in a region
    transferred to all communities of the region with the exception
    of Urban Aid Cities.'" In re N.J.A.C. 5:96 
    II, supra
    , 221 N.J.
    at 30 n.4 (alterations in original) (citations omitted).
    42                              A-3323-15T1
    court   computations         of    housing      need       and    municipal           obligations
    based on those methodologies."                 
    Ibid. The Court stated
    that the
    starting      point    for   a    determination            of     a    municipality's         fair
    share responsibility is the prior round unfulfilled obligations.
    
    Ibid. Requiring municipalities to
       undertake         a     retrospective
    "separate and discrete" additional calculation for affordable
    housing need does not follow the First or Second Round Rules.
    It mandates an entirely new obligation unauthorized by the FHA.
    The judge concluded that "New Jersey's affordable housing
    need    is    cumulative       and     there    can       be     no    gaps      in    time   left
    unaddressed."         He based this conclusion on his interpretation of
    Mount Laurel II, stating the Court "found the obligation to meet
    the prospective lower income housing need of the region is, by
    definition,      one    that      is   met     year       after       year    in    the   future,
    throughout      the    years      of    the     particular             projection         used   in
    calculating prospective need."                      However, the Court's statement
    was aimed at the practical effects of establishing prospective
    need, stating:
    The Mount Laurel obligation to meet the
    prospective      [looking       forward      not
    retrospectively] lower income housing need
    of the region is, by definition, one that is
    met   year   after   year    in    the   future,
    throughout the years of the particular
    projection used in calculating prospective
    need.      In this sense the affirmative
    obligation    to     provide     a     realistic
    opportunity to construct a fair share of
    43                                         A-3323-15T1
    lower income housing is met by a "phase-in"
    over those years; it need not be provided
    immediately. Nevertheless, there may be
    circumstances   in   which    the   obligation
    requires   zoning   that   will   provide   an
    immediate   opportunity   --   for   instance,
    zoning to meet the region's present lower
    income housing need.     In some cases, the
    provision of such a realistic opportunity
    might result in the immediate construction
    of lower income housing in such quantity as
    would radically transform the municipality
    overnight.    Trial courts shall have the
    discretion, under those circumstances, to
    moderate the impact of such housing by
    allowing even the present need to be phased
    in over a period of years.        Such power,
    however, should be exercised sparingly. The
    same   power   may   be  exercised    in   the
    satisfaction of prospective need, equally
    sparingly, and with special care to assure
    that such further postponement will not
    significantly   dilute   the    Mount   Laurel
    obligation.
    [Mount Laurel 
    II, supra
    , 92 N.J. at 218-19
    (emphasis added).]
    The   language     quoted    by   the   judge     pertained   to   the   Court's
    recognition that phasing in was an option for municipalities in
    calculating      present    and   prospective       need.     Therefore,       the
    judge's reliance on Mount Laurel II for the proposition that
    there   can   be     no     gap   periods    is     respectfully    misplaced.
    Furthermore, the FHA, enacted after Mount Laurel II, and the
    Court's opinion in In re N.J.A.C. 5:96 II do not support such a
    conclusion.

    Whether       to     establish    a    new     methodology         that   imposes
    retrospective     calculations       for   determining       affordable       housing
    needs   during    the    gap   period,     which    would    be   in    addition     to
    satisfying       prior     round     unmet         present    and        prospective
    obligations, is best left for consideration by the Legislative
    and Executive branches.         As the Court explained in 2013, when it
    invalidated COAH's Third Round Rules:
    The   Legislature    may    determine   to
    authorize    new   avenues    for    addressing
    regional    need   and    the   promotion    of
    affordable housing.     And, it may do so in
    ways that we do not attempt to circumscribe
    in this opinion because we do not know the
    breadth   of   considerations   that   may   be
    brought     forth    through      informational
    legislative    hearings    on   the    subject.
    Nevertheless, it is the Legislature that
    must devise the parameters to such an
    approach.   It must craft new legislation if
    that is the course it wishes to take.       Our
    courts can and should exercise caution and
    defer to such solutions when appropriately
    drafted by the Legislature.     See N.J. Ass'n
    on [Corr.] v. Lan, 
    80 N.J. 199
    , 220 (1979)
    (acknowledging importance of deference to
    legislative enactments addressing general
    welfare (citation omitted)); Roe v. Kervick,
    
    42 N.J. 191
    , 230 (1964) (recognizing value
    of deference when reasonable minds could
    differ and issue to be remedied "involves a
    concept which varies with the needs of the
    times").
    Although the Legislature may consider
    enacting an alternative form of remedy for
    the promotion of affordable housing in the
    housing regions of this state, see Hills

    not changed; the judiciary's ultimate duty
    to   enforce   it   has   not  changed;   our
    determination to perform that duty has not
    changed."),       enforcement     of      the

    Deferring to the Legislature on such policy considerations
    is especially important here because COAH is a "legislatively
    created, unique device for securing satisfaction of Mount Laurel
    obligations."       In re N.J.A.C. 5:96 
    II, supra

    As the Court stated, it is not our role to become a replacement

    constitutional basis for the judiciary, much less this court, to

    We     reject   the    contention    that   the   doctrine   of   judicial
    estoppel bars the challenge to the court's holding as to the

    judicial estoppel using an abuse of discretion standard.                State,

    Although the [FHA] clearly states that
    the State Constitution's affordable housing
    obligation is comprised of "present and
    prospective need" for affordable housing

    intent of the Legislature behind the [FHA],
    and imposed a retroactive obligation for the
    so-called gap period.    The purpose of this
    bill   is    to   eliminate    any   possible
    misconception    with    respect    to    the
    Legislature's   intent    to    ensure   that
    determination of a municipality's fair share
    of affordable housing will be based upon the
    present and prospective need for affordable
    housing, as clearly set forth in the [FHA],
    and that a fair share obligation will not
    include a retrospective need that may have
    arisen during any "gap period" between
    housing cycles.

    Judicial estoppel is not a favored remedy because of its
    draconian consequences.          It is to be invoked only in limited
    circumstances:
    It is . . . generally recognized that
    judicial   estoppel   is   an   "extraordinary
    remedy," which should be invoked only "when
    a   party's    inconsistent    behavior   will
    otherwise   result   in   a   miscarriage   of
    justice."   Ryan Operations G.P. v. Santiam-

    truth of either statement."). Thus, as with
    other claim and issue preclusion doctrines,
    judicial estoppel should be invoked only in
    those circumstances required to serve its
    stated purpose, which is to protect the
    integrity of the judicial process.
    [Id. at 608 (footnote omitted).]
    In Ali v. Rutgers, 
    166 N.J. 280
    , 288 (2000), our Supreme Court
    confirmed that judicial estoppel is an "extraordinary remedy."
    The facts presented on this appeal do not warrant application of
    this remedy.
    In invoking the doctrine of judicial estoppel and imposing
    a   "separate   and   discrete"   gap-period   obligation,    the   judge
    relied on our opinion in In re Six Month.        We conclude that the
    court's    reliance   is   misplaced.    We    reach   that   conclusion
    primarily because the parties and issues in In re Six Month were
    substantially different than here, and since issuing our opinion
    in In re Six Month, the Court provided Mount Laurel judges with
    further guidelines and principles in In re N.J.A.C. 5:96 II.
    As to the dissimilarity of issues, our focus in In re Six
    Month was on COAH's interim procedural rules designed to address
    a six-year period between 1999 and 2004.        
    Supra, 372 N.J. Super. at 68
    .    In In re Six Month, we identified the sole issue:
    These [seven] appeals concern only N.J.A.C.
    5:91-14.3, which provides a mechanism for
    municipalities previously certified in the
    second round to receive an extension of
    their substantive certification status and,
    49                           A-3323-15T1
    therefore, further protection from civil
    action   remedies, for  up   to   one  year
    following the adoption of the third-round
    rules, well beyond the previously scheduled
    1999 expiration of second-round standards
    and methodology.
    [Ibid.]
    Here, the issue is whether a retrospective "separate and
    discrete" gap-period obligation is authorized by (1) the core
    principles of the Mount Laurel doctrine, as codified in the FHA;
    and (2) In re N.J.A.C. 5:96 II.             There, we were not asked to
    address,   and   we    did   not   sanction,      a    gap-period    affordable
    housing obligation, on top of prior unfulfilled obligations and
    present and prospective needs.           Rather, we temporarily suspended
    substantive certifications granted by COAH pursuant to N.J.A.C.
    5:91-14.3, subject to rule modifications.                  
    Id. at 105.
         As to
    the   dissimilarity     of      parties,   none       of    the   Ocean    County
    municipality entities participated in In re Six Month.
    V.
    In sum, we conclude that the core principles of the Mount
    Laurel doctrine, as codified in the FHA, and the guidelines and
    principles established by the New Jersey Supreme Court in In re
    N.J.A.C. 5:96 II, do not authorize a retrospective new "separate
    and   discrete"       affordable     housing      gap-period        obligation.
    Following In re N.J.A.C. 5:96 II, a town should start with its
    unfulfilled   prior     round    obligations      and      then   establish     its
    50                                  A-3323-15T1
    present and prospective need in establishing a municipality's
    fair share Mount Laurel obligation.
    Finally,     we     emphasize      that      our       holding      today   does       not
    ignore    housing      needs    that     arose         in    the    gap    period      or     a
    municipality's          obligation          to         otherwise          satisfy           its
    constitutional fair share obligations.                      As Mr. Reading candidly
    acknowledged,        "[low-    and     moderate-income]             households        formed
    during the gap period may no longer represent an affordable
    housing   need    due    to    a    variety       of    reasons         including    death,
    changes   in    income,       increase    or      decrease         in    household     size,
    retirement and/or relocation outside of New Jersey."                             However,
    he also stated that housing need from the gap period would be
    "partially     included"       by    those        living      in    "over[]crowded           or
    deficient      housing    units      that      are      encompassed         in   the        new
    calculation     of    [p]resent      [n]eed."           Therefore,         the   scope       of
    present need should be dictated by identifiable housing need
    characteristics as found by the reviewing Mount Laurel judge
    when examining the evidence presented.14                       In this context, the
    focus remains – as it has for the last forty years - on the
    constitutional          obligation           of         realistically            affording
    14
    The Municipal Group asserted in its amicus brief that
    "municipalities   presented  facts   to   show  that developers
    constructed roughly 90,000 rental units affordable to low[-] or
    moderate-income households during the gap period."
    51                                        A-3323-15T1
    opportunities for construction of a municipality's fair share of
    present      and    prospective          need        for      low-     and       moderate-income
    housing.
    We reach our conclusion emphasizing: (1) the core of the
    Mount Laurel doctrine is a municipality "would satisfy [its]
    constitutional obligation by affirmatively affording a realistic
    opportunity        for    the   construction             of      its    fair       share    of    the
    present and prospective regional need for low[-] and moderate[-
    income] income housing," Mount Laurel 
    II, supra
    , 92 N.J. at 205
    (emphasis      added);      (2)      a    realistic              opportunity           depends     on
    "whether there is in fact a likelihood -- to the extent economic
    conditions allow -- that the lower income housing will actually
    be   constructed,"        
    id. at 222;
         (3)        the    FHA       codified       the   core
    constitutional holding undergirding the Mount Laurel obligation,
    In re N.J.A.C. 5:96 
    I, supra
    , 215 N.J. at 584, and specifically
    defined "prospective need" as a forward projection of housing
    needs    "based      on    development          and        growth       .    .    .    [which     is]
    reasonably     likely      to   occur      in        a     region      or    a    municipality,"
    N.J.A.C. 5:92-1.3; (4) the FHA charged COAH with determining
    "State and regional present and prospective need for low[-] and
    moderate[-income] housing," In re N.J.A.C. 5:96 
    I, supra
    , 215
    N.J.    at   589    (emphasis        added);         (5)      although           the   Legislature
    amended the FHA twelve times during the gap period, it did not
    52                                          A-3323-15T1
    impose    a   retrospective     "separate    and     discrete"    gap-period
    obligation; (6) although the Appellate Division and the Supreme
    Court    likewise   had    opportunities    during    the   gap   period    to
    require a "separate and discrete" gap-period obligation, such an
    obligation was not imposed, and instead remained steadfast to
    the FHA's focus on State and regional present and prospective
    need for low- and moderate-income housing; (7) identified low-
    and moderate-income households formed during the gap period in
    need of affordable housing can be captured in a municipality's
    calculation of present need; and (8) under our tripartite system
    of jurisprudence, imposing a "separate and discrete" gap-period
    obligation is best left for consideration by the Legislative and
    Executive branches of government where the issues can be fairly
    and fully debated in the public forum.
    Reversed and remanded for further proceedings consistent
    with this opinion.        We do not retain jurisdiction.
