    JAMES BOYAJIAN ET AL. v. PLANNING AND
    ZONING COMMISSION OF THE
    TOWN OF VERNON
    (AC 43273)
    Prescott, Suarez and Vitale, Js.
    Syllabus
    The plaintiffs, B and J Co., operated a liquor store in the town of Vernon.
    The town’s zoning regulations required establishments that sell alcoholic
    liquors to be separated by a distance of no less than 3000 feet. T filed
    an application with the town’s zoning board of appeals for a variance
    that would allow him to establish a liquor store in a location that was
    2935 feet from the plaintiffs’ store. The board scheduled a public hearing
    on the application and provided notice of the hearing to the abutting
    landowners by letter and to the general public in a local newspaper. At
    the conclusion of the hearing, which the plaintiffs did not attend, the
    board voted to approve the variance. T then submitted an application
    to the town’s planning and zoning commission for a special permit to
    allow the sale of alcohol at the property. After a public hearing, at which
    B spoke on the record and claimed that the underlying variance was void,
    the commission approved the special permit application. The plaintiffs
    appealed the commission’s decision to the Superior Court, claiming,
    inter alia, that the variance was void, that the commission should not
    have relied on the variance in determining whether to grant the special
    permit, and that the board lacked the authority to grant the variance.
    The trial court denied the appeal, and the plaintiffs, on the granting of
    certification, appealed to this court. Held that the plaintiffs’ failure to
    appeal from the decision of the board that granted the application for
    the variance rendered their opposition to the commission’s decision to
    grant the special permit an impermissible collateral attack on the validity
    of the variance: once the statutory period to appeal the board’s decision
    to grant the variance had expired, the decision became final; moreover,
    collateral attacks on the decisions of zoning authorities are generally
    impermissible in light of the need for stability in land use planning and
    the need for justified reliance by the interested parties; furthermore,
    the plaintiffs failed to demonstrate that either of the conditions that
    may permit a collateral attack on a previously unchallenged zoning
    decision were satisfied, as, because the board acted within its statutorily
    authorized power to vary zoning regulations, its decision was not so far
    outside of what could have been regarded as a valid exercise of zoning
    power that there could not have been any justified reliance on it, and
    the plaintiffs’ argument that the continued maintenance of the variance
    would violate a strong public policy because it varied the town’s zoning
    regulations was unavailing because it merely described the purpose of
    a variance.
    Argued March 3—officially released July 20, 2021
    Procedural History
    Appeal from the decision of the defendant granting
    a special permit application filed by Jagdev Toor,
    brought to the Superior Court in the judicial district of
    Tolland where the court, Sicilian, J., granted the
    motion of Jagdev Toor to intervene as a defendant;
    thereafter, the matter was tried to the court, Hon. Sam-
    uel J. Sferrazza, judge trial referee; judgment denying
    the appeal, from which the plaintiffs, on the granting
    of certification, appealed to this court. Affirmed.
    James H. Howard, for the appellants (plaintiffs).
    Louis A. Spadaccini, with whom, on the brief, were
    Martin B. Burke and Roseann Canny, for the appellee
    (defendant).
    Opinion
    PRESCOTT, J. This appeal requires us to consider
    whether the plaintiffs, who failed to appeal from a deci-
    sion of the local zoning board of appeals to grant a
    variance; see General Statutes § 8-8 (b); may neverthe-
    less collaterally attack the validity of that variance by
    opposing, before the local planning and zoning commis-
    sion, a special permit application related to the property
    to which the variance attached. We conclude that the
    plaintiffs may not collaterally attack the validity of the
    variance.
    The plaintiffs, James Boyajian and JPB, LLC,1 appeal
    from the judgment of the trial court. The trial court
    denied the plaintiffs’ appeal from the decision of the
    defendant, the Planning and Zoning Commission of the
    Town of Vernon (commission), granting a special per-
    mit application filed by the intervening defendant, Jag-
    dev Toor.2 As they did before the trial court, the plain-
    tiffs claim that (1) the variance that the Zoning Board
    of Appeals of the town of Vernon (board) granted to
    Toor, and which otherwise entitled Toor to receive the
    special permit, was void, (2) the commission, in grant-
    ing the special permit, improperly relied on the vari-
    ance, and (3) the board lacked the authority to grant
    the variance. Essentially, each of these claims is a chal-
    lenge to the validity of the variance granted to Toor by
    the board. We conclude that the plaintiffs’ failure to
    appeal from the decision of the board that granted
    Toor’s application for the variance renders the plain-
    tiffs’ opposition to the commission’s decision to grant
    Toor’s special permit application an impermissible col-
    lateral attack on the validity of the variance. Accord-
    ingly, we affirm the judgment of the Superior Court.
    The following facts and procedural history are rele-
    vant to our resolution of this appeal. Boyajian is the
    sole owner of JPB, LLC. The plaintiffs operate Riley’s
    Liquor, located at 312 Hartford Turnpike in Vernon.
    The Vernon Zoning Regulations (zoning regulations)
    mandate that establishments that sell alcoholic liquors
    be separated by a distance of no less than 3000 feet,
    measured in a straight line from the main public access
    doors of each establishment. Vernon Zoning Regs.,
    § 17.1.2. Toor sought to open and operate a liquor store
    at a commercial building located at 206 Talcottville
    Road in Vernon (property), which was located 2935 feet
    from Riley’s Liquor. On or around January 31, 2018,
    Toor filed an application to the board for a variance3
    from the 3000 foot separating distance requirement by
    sixty-five feet to permit the 2935 foot separating dis-
    tance between the property and Riley’s Liquor. In the
    absence of the variance, the proposed liquor store
    would have violated the distance requirement contained
    in the zoning regulations.
    The board scheduled a public hearing on the variance
    application for April 18, 2018. In anticipation of the
    hearing, the board provided notice of the variance appli-
    cation and hearing by letter to abutting property owners
    and to the public in the Journal Inquirer. On April 18,
    2018, the board held a public hearing and, on its conclu-
    sion, voted to approve the variance by a four to one
    vote. The plaintiffs did not attend the hearing. The board
    notified Toor of its approval on April 19, 2018. At no
    point did the plaintiffs appeal from the board’s decision
    to grant the variance.4
    In July, 2018, Toor submitted to the commission an
    application for a special permit for the sale of alcohol
    at the property. The commission held a public hearing
    on the special permit application on August 16, 2018,
    at which Boyajian spoke on the record5 and expressed,
    inter alia, his contention that the underlying variance
    was void.6 At the conclusion of the hearing, the commis-
    sion voted to approve the special permit application by
    a five to one vote and noted that the variance was ‘‘in
    effect’’ at the time of the hearing.7
    The plaintiffs appealed the commission’s approval of
    the special permit application to the Superior Court. In
    their brief to the trial court, the plaintiffs argued, in
    relevant part, that (1) the variance was void, (2) the
    board lacked the authority to grant the variance, (3)
    the commission’s reliance on the void variance was a
    ‘‘flawed foundation upon which [it] premised its’’
    approval of the special permit, and (4) the commission
    ‘‘ignored’’ the zoning regulations, which otherwise pro-
    hibited approval of the special permit.8
    The trial court, Hon. Samuel J. Sferrazza, judge trial
    referee, denied the appeal. In considering whether the
    commission should have independently reviewed the
    property’s compliance with the statutory separating dis-
    tance requirement and the validity of the underlying
    variance, the court recognized that the plaintiffs’ argu-
    ments posed ‘‘some very interesting and challenging
    legal issues.’’9 ‘‘The court determine[d], however, that
    it need not resolve those conundrums. This is because
    no appeal was taken from the decision in which all
    these issues could have been adjudicated. Whether the
    [board’s] decision was erroneous became immaterial
    once the appeal period expired.’’ The trial court charac-
    terized the plaintiffs’ contention with the commission’s
    decision, insofar as the plaintiffs sought independent
    review of the commission’s decision to grant a special
    permit predicated on an allegedly void variance, as an
    impermissible ‘‘collateral attack on an unappealed . . .
    decision . . . .’’ Because the trial court concluded that
    the attack did not fall under one of the potential excep-
    tions the Supreme Court identified in Upjohn Co. v.
    Zoning Board of Appeals, 
    224 Conn. 96
    , 104–105, 
    616 A.2d 793
     (1992), the plaintiffs could not prevail on the
    issue. Pursuant to Practice Book § 81-1 et seq. and § 8-
    8 (o), the plaintiffs requested certification to appeal to
    this court. Upon consideration of the plaintiffs’ petition,
    we granted review.
    The plaintiffs claim that the trial court improperly
    upheld the commission’s decision to grant the special
    permit application. More specifically, the plaintiffs
    argue that (1) the underlying variance granted to Toor
    was void, (2) in determining whether Toor qualified for
    the special permit, the commission should have applied
    the standards prescribed by the zoning regulations,
    rather than relying solely on the variance, and (3) the
    board lacked the statutory authority to grant the vari-
    ance.10 The defendant argues in response that the plain-
    tiffs’ opposition to the commission’s decision to grant
    the special permit constitutes an impermissible collat-
    eral attack on the board’s approval of the variance. It
    argues that the commission and the trial court properly
    rejected the plaintiffs’ arguments on the ground that
    the plaintiffs should have raised their claim on direct
    appeal from the board’s decision to grant the variance.
    We agree with the defendant.
    We first set forth the relevant law, including our stan-
    dard of review. On appeal, we review the trial court’s
    legal conclusion that the plaintiffs’ opposition to the
    commission’s decision to grant the special permit appli-
    cation is an impermissible collateral attack on the
    board’s decision to grant the variance application. Reso-
    lution of this issue presents a question of law over
    which our review is plenary. Santarsiero v. Planning &
    Zoning Commission, 
    165 Conn. App. 761

    sions of law in its memorandum of decision [in this

    Zoning Commission, 
    193 Conn. App. 42
    , 53,

     (2019). An applicant may apply for a special permit
    from a zoning commission; see General Statutes § 8-2
    (a); and ‘‘[i]t is well settled that [for a commission to
    grant] a special permit, an applicant must satisf[y] all
    conditions imposed by the regulations.’’ (Internal quota-

    ,
    591, 
    170 A.3d 73
     (2017). ‘‘[A]lthough it is true that the
    zoning commission does not have discretion to deny a
    special permit when the proposal meets the standards,
    it does have discretion to determine whether the pro-
    posal meets the standards set forth in the regulations.
    If, during the exercise of its discretion, the zoning com-
    mission decides that all of the standards enumerated
    in the special permit regulations are met, then it can no
    longer deny the application. The converse is, however,
    equally true. Thus, the zoning commission can exercise
    its discretion during the review of the proposed special
    [permit], as it applies the regulations to the specific
    application before it.’’ (Emphasis omitted; internal quo-
    tation marks omitted.)

    when two basic requirements are satisfied: (1) the vari-
    ance must be shown not to affect substantially the com-
    prehensive zoning plan, and (2) adherence to the strict
    letter of the zoning ordinance must be shown to cause
    unusual hardship unnecessary to the carrying out of the
    general purpose of the zoning plan.’’ (Internal quotation

    ,

     (2020). ‘‘Interpretation of the

    Although an aggrieved individual may challenge the
    decision of a zoning authority; see, e.g., General Statutes
    § 8-8 (b); as a general rule, ‘‘one may not institute a
    collateral action challenging the decision of a zoning
    authority.’’ Torrington v. Zoning Commission, supra,
    
    261 Conn. 767
    . ‘‘A collateral attack is an attack upon

    224 Conn. 103
     (sug-
    gesting that ‘‘[i]t would be fundamentally unfair . . .
    to permit’’ collateral attack).
    ‘‘The reason for the rule against collateral attack is
    well stated in these words: The law aims to invest judi-
    cial transactions with the utmost permanency consis-
    tent with justice. . . . Public policy requires that a term
    be put to litigation and that judgments, as solemn
    records upon which valuable rights rest, should not
    lightly be disturbed or overthrown. . . . [T]he law has
    established appropriate proceedings to which a judg-
    ment party may always resort when he deems himself
    wronged by the court’s decision. . . . If he omits or
    neglects to test the soundness of the judgment by these
    or other direct methods available for that purpose, he
    is in no position to urge its defective or erroneous
    character when it is pleaded or produced in evidence
    against him in subsequent proceedings. Unless it is
    entirely invalid and that fact is disclosed by an inspec-
    tion of the record itself the judgment is invulnerable to
    indirect assaults upon it.’’ (Internal quotation marks

    a party to appeal from the action of a zoning authority

    Thus, ‘‘the general rule [is] that one may not institute
    a collateral action challenging the decision of a zoning
    authority. . . . [T]he rule requiring interested parties
    to challenge zoning decisions in a timely manner rest[s]
    in large part . . . on the need for stability in land use
    planning and the need for justified reliance by all inter-
    ested parties—the interested property owner, any inter-
    ested neighbors and the town—on the decisions of the

    In Upjohn Co. v. Zoning Board of Appeals, 
    supra,
    224 Conn. 102
    , our Supreme Court determined that a
    plaintiff may not collaterally attack a condition to an
    approved zoning permit application because the plain-
    tiff had failed to appeal the condition at the time it was
    imposed. The plaintiff in Upjohn Co. had applied to the
    local planning and zoning commission to build struc-
    tures on its property, and the commission approved the
    zoning permit application, subject to several conditions.
    
    Id., 98
    . The plaintiff ‘‘did not appeal or otherwise chal-
    lenge the validity or imposition of’’ one condition with
    which it later failed to comply. 
    Id., 98
    –99. When a zoning
    enforcement officer served the plaintiff with a cease and
    desist order for failure to comply with the condition,
    the plaintiff appealed to the zoning board of appeals
    and, subsequently, to the trial court, contesting the
    validity of the underlying condition. 
    Id., 99
    . The trial
    court sustained the appeal. 
    Id., 100
    .
    On review, our Supreme Court agreed with the zoning
    board of appeals that ‘‘the trial court incorrectly con-
    cluded that [the plaintiff] could collaterally attack the
    validity of [the] condition . . . in the enforcement pro-
    ceedings more than three years after its imposition by
    the commission and acceptance by [the plaintiff].’’ 
    Id.
    ‘‘We conclude that [the plaintiff], having secured the
    permits . . . subject to [the] condition . . . and not
    having challenged the condition by appeal at that time,
    was precluded from doing so in the [later] enforcement
    proceedings . . . . [W]hen a party has a statutory right
    of appeal from the decision of an administrative agency,
    he may not, instead of appealing, bring an independent
    action to test the very issue which the appeal was
    designed to test. . . . It would be inconsistent with
    th[e] needs [of stability in land use planning and justified
    reliance by interested parties] to permit, in this case,
    a challenge to a condition imposed on a zoning permit
    when the town seeks to enforce it more than three
    years later.’’ (Citations omitted; internal quotation
    marks omitted.) 
    Id., 102
    .
    Subsequent cases have applied the rule set forth in
    Upjohn Co. In a somewhat related procedural context,
    our Supreme Court in Torrington v. Zoning Commis-
    sion, supra, 
    261 Conn. 761
    , 767–68, applied the rule set
    forth in Upjohn Co. to an action in which a plaintiff
    attacked a stipulated judgment it had previously failed
    to appeal. Because the plaintiff had ample notice and
    opportunity to challenge the judgment at the time it
    was entered, it could ‘‘not [later] collaterally attack the
    stipulated judgment.’’ 
    Id., 767, 770
    .
    In Santarsiero v. Planning & Zoning Commission,
    supra, 
    165 Conn. App. 779
    , this court upheld a trial
    court’s determination that a collateral attack by the
    plaintiffs, nearby property owners, was impermissible
    under the circumstances. The zoning board in Santar-
    siero had granted an application filed by a landowner
    for a variance to construct a restaurant with a drive-
    up window in a zone that specifically prohibited such
    windows. 
    Id., 764
    –65. The plaintiffs received notice of
    the hearing but did not appeal the decision of the board.
    
    Id., 765, 777
    . Relying on the variance, the landowner
    applied for a special exception11 from the local planning
    and zoning commission, and the commission granted
    the exception. 
    Id., 765
    –66. Following three years of
    related disputes, the plaintiffs appealed to the trial court
    and attacked, inter alia, the validity of the variance. 
    Id., 770
    . The trial court dismissed the plaintiff’s appeal. 
    Id.
    On appeal to this court, the plaintiffs in Santarsiero
    reiterated their argument that the trial court improperly
    upheld the actions of the commission because the zon-
    ing board’s decision to grant the variance, on which
    the commission’s decision was predicated, ‘‘was not a
    valid exercise of zoning power and there could not have
    been any justified reliance on it.’’ 
    Id., 778
    . This court
    disagreed. 
    Id., 776
    . This court noted that the ‘‘variance
    formed the basis of the commission’s authority to grant
    the . . . special exception to the defendant,’’ and the
    plaintiffs failed to appeal from the variance. 
    Id., 776
    –77.
    Accordingly, the plaintiff’s opposition to the commis-
    sion’s decision to grant the special exception applica-
    tion, premised on its opposition to the board’s granting
    of the variance application, constituted an impermissi-
    ble collateral attack. 
    Id., 779
    .
    Upjohn Co. and its progeny govern our resolution of
    the present appeal, and Santarsiero is on all fours with
    the case before us. Nothing in the record suggests that
    the plaintiffs in the present case were prevented from
    raising by direct appeal their substantive contentions
    concerning the validity of the variance. Yet, just as in
    Santarsiero, the plaintiffs failed to appeal from the
    board’s decision to grant the variance. See 
    id., 777
    . Once
    the statutory period to appeal the board decision had
    expired, the board’s decision to grant the variance
    became final. See Upjohn Co. v. Zoning Board of
    Appeals, 
    supra,
     
    224 Conn. 102
    . Nevertheless, the plain-
    tiffs attacked the validity of the variance at the commis-
    sion’s hearing on the special permit application. Once
    again, just as in Santarsiero, the variance here ‘‘formed
    the basis of the commission’s authority to grant the
    [special permit] to’’ Toor; Santarsiero v. Planning &
    Zoning Commission, supra, 
    165 Conn. App. 776
    ; which,
    according to the plaintiffs, required the commission to
    deny the special permit application. The commission
    nonetheless approved the special permit application.12
    The plaintiffs asserted the same argument to the trial
    court and insisted that the commission’s reliance on
    the variance was misplaced because the variance was
    void. The trial court concluded that the plaintiffs’ argu-
    ment concerning the variance was an impermissible
    substitute for an appeal of the board’s decision. Finally,
    the grounds on which the plaintiffs appeal to this court
    rest entirely on their challenges to the validity of the
    variance.13 The plaintiffs’ failure to appeal the board’s
    granting of the variance ostensibly forecloses consider-
    ation of the merits of their arguments. See Bochanis
    v. Sweeney, 
    148 Conn. App. 616
    , 627–28, 
    86 A.3d 486
    (prohibiting collateral ‘‘attack on the substance of the
    wetlands permit, which . . . the plaintiffs could have
    done’’ by filing appeal (emphasis in original)), cert.
    denied, 
    311 Conn. 949
    , 
    90 A.3d 978
     (2014). Conse-
    quently, their collateral attack on the variance is imper-
    missible, unless it falls within one of the exceptions to
    the general rule barring collateral attacks.
    Our Supreme Court has stated that there may be
    two types of ‘‘exceptional cases’’ wherein ‘‘a collateral
    attack’’ may be permissible. Upjohn Co. v. Zoning
    Board of Appeals, 
    supra,
     
    224 Conn. 104
    –105. Our
    Supreme Court explained, ‘‘[w]e recognize . . . that
    there may be exceptional cases in which a previously
    unchallenged condition was so far outside what could
    have been regarded as a valid exercise of zoning power
    that there could not have been any justified reliance
    on it, or in which the continued maintenance of a pre-
    viously unchallenged condition would violate some
    strong public policy. It may be that in such a case a
    collateral attack on such a condition should be permit-
    ted. We leave that issue to a case that, unlike this case,
    properly presents it.’’ Id.14
    ‘‘In Gangemi v. Zoning Board of Appeals, 
    255 Conn. 143
    , 150–51, 
    763 A.2d 1011
     (2001), [our Supreme Court]
    converted this dictum into a holding, and concluded
    that the continued maintenance of [a] previously
    unchallenged condition . . . violated the strong public
    policy against restraints on alienation.’’ Torrington v.
    Zoning Commission, supra, 
    261 Conn. 768
    . As we have
    noted, the plaintiffs’ attack on the commission’s deci-
    sion to grant the special permit here is premised on the
    board’s alleged lack of authority to grant the variance.
    Thus, we consider, in turn, the applicability of the
    exceptions recognized by Upjohn Co. to the actions
    taken by the board in the present case.
    We first consider whether the board’s decision to
    grant the variance fell ‘‘so far outside what could [be]
    regarded as a valid exercise of [its] zoning power that
    there could not have been any justified reliance on it
    . . . .’’ Upjohn Co. v. Zoning Board of Appeals, 
    supra,
    224 Conn. 104
    –105. ‘‘[I]t must be an exceptional [case]
    that will justify disturbing the stability of unchallenged
    land use decisions. . . . It is not enough that the con-
    duct in question was in violation of the applicable zon-
    ing statutes or regulations. . . . [A] litigant who seeks
    to invoke this exception must meet a very high stan-
    dard.’’ (Citation omitted; internal quotation marks omit-
    ted.) Torrington v. Zoning Commission, supra, 
    261 Conn. 768
    ; see, e.g., Gay v. Zoning Board of Appeals,
    
    59 Conn. App. 380
    , 388, 
    757 A.2d 61
     (2000) (permitting
    collateral attack of condition ‘‘imposed by [a] board
    on a parcel that was not the subject of the variance
    application before it’’ under first exception of Upjohn
    Co.). ‘‘[T]he party seeking to invoke the exception to
    the general rule barring collateral attack on a previously
    unchallenged land use decision . . . ha[s] the burden
    to establish that the [board or] commission [acted] . . .
    without an adequate basis on which to do so.’’ Torring-
    ton v. Zoning Commission, supra, 773. ‘‘The question
    of whether an extrajudicial act of a zoning authority is
    so far outside the valid exercise of zoning power that
    there could not have been any justified reliance on it,
    necessarily permits, in an appropriate case, some
    inquiry into the reasons for that reliance.’’ Id., 775–76;
    see also Santarsiero v. Planning & Zoning Commis-
    sion, supra, 
    165 Conn. App. 779
    .
    Section 8-6 provides in relevant part: ‘‘(a) The zoning
    board of appeals shall have the following powers and
    duties . . . (3) to determine and vary the application
    of the zoning . . . regulations in harmony with their
    general purpose and intent and with due consideration
    for conserving the public health, safety, convenience,
    welfare and property values solely with respect to a
    parcel of land where, owing to conditions especially
    affecting such parcel but not affecting generally the
    district in which it is situated, a literal enforcement of
    such . . . regulations would result in exceptional diffi-
    culty or unusual hardship so that substantial justice
    will be done and the public safety and welfare secured,
    provided that the zoning regulations may specify the
    extent to which uses shall not be permitted by variance
    in districts in which such uses are not otherwise
    allowed. . . .’’
    As we have stated, ‘‘[i]nterpretation of the zoning
    regulations is a function of a zoning board of appeals.
    The variance power exists to permit what is prohibited
    in a particular zone.’’ (Internal quotation marks omit-
    ted.) Santarsiero v. Planning & Zoning Commission,
    supra, 
    165 Conn. App. 779
    . The zoning regulations, simi-
    larly, recognize the power of the board to hear and
    decide variance applications. Vernon Zoning Regs.,
    § 17.2.
    By granting the variance at issue, the board acted
    squarely within its statutorily authorized power to vary
    zoning regulations. General Statutes § 8-6 (a) (3). The
    board held a hearing to decide whether to approve the
    application for the variance, which would vary the 3000
    foot separating distance requirement between liquor
    stores under the zoning regulations. Vernon Zoning
    Regs., § 17.1.2. The record reflects that the board con-
    sidered the significance of a sixty-five foot variance
    as well as any alleged hardship. After discussion and
    consideration of the application, the board granted the
    application, that is, it varied the 3000 foot requirement
    to permit a separating distance of 2935 feet. See id.
    The plaintiffs, however, contend that the board
    impermissibly granted the variance because Toor failed
    to establish a sufficient unique hardship that affected
    the property. The plaintiffs also argue that, because
    ‘‘the location of property is not a legal basis for the
    granting of a variance . . . the statute confer[red] no
    authority upon the [board] to grant such a variance.’’
    The plaintiffs also asserted that the effect of the vari-
    ance conflicted with other zoning regulations. Each of
    these arguments inherently accepts the ‘‘adequate basis
    on which’’ the board acted—the statutory power con-
    veyed on the board to vary regulations—and forecloses
    the suggestion that granting the variance constituted an
    extrajudicial act. Torrington v. Zoning Commission,
    supra, 
    261 Conn. 769
    –70, 773. Assuming, arguendo, that
    the plaintiffs’ arguments, as the trial court noted, could
    have presented a ‘‘colorable claim’’ in an appeal of the
    board’s decision, the plaintiffs’ arguments nonetheless
    fail to render the board’s action so far outside what
    could be regarded as a valid exercise of the board’s
    statutory power that there could not have been any
    justified reliance on it. That is to say, because the board
    maintained the power to vary zoning regulations, we
    are unconvinced that the plaintiffs have met the ‘‘very
    high standard’’ that would trigger an acceptable collat-
    eral attack on the board’s action. Torrington v. Zoning
    Commission, supra, 768.
    We now turn to the second Upjohn Co. exception. The
    court in Upjohn Co. suggested that, if ‘‘the continued
    maintenance of a previously unchallenged condition
    would violate some strong public policy,’’ a collateral
    attack may be warranted. Upjohn Co. v. Zoning Board
    of Appeals, 
    supra,
     
    224 Conn. 105
    . ‘‘We begin by empha-
    sizing that, under this prong of the Upjohn Co. formula-
    tion, we focus, not on the state of affairs that existed
    when the condition at issue originally was imposed, but
    on the current state of affairs in which the condition
    is being enforced. . . . [W]e focus on the continued
    maintenance of the condition, and whether, irrespective
    of the fact that the condition was previously unchal-
    lenged, it nonetheless currently violate[s] some strong
    public policy.’’ (Citation omitted; internal quotation
    marks omitted.) Gangemi v. Zoning Board of Appeals,
    
    supra,
     
    255 Conn. 150
    –51. As under the first exception,
    review under this exception demands a high standard.
    Compare, e.g., 
    id., 151, 157
     (permitting collateral attack
    on condition to variance that contradicted ‘‘the strong
    and deeply rooted public policy in favor of the free and
    unrestricted alienability of property’’ and failed to serve
    ‘‘legal and useful purpose’’ (internal quotation marks
    omitted)), with George v. Watertown, 
    85 Conn. App. 606
    , 611–12, 
    858 A.2d 800
     (prohibiting collateral attack
    on commission action that implicated strong public pol-
    icy interest but fell within ‘‘conformity [of] the law’’),
    cert. denied, 
    272 Conn. 911
    , 
    863 A.2d 702
     (2004), and
    Caltabiano v. L & L Real Estate Holdings II, LLC, 
    122 Conn. App. 751
    , 762, 
    998 A.2d 1256
     (2010) (prohibiting
    collateral attack on decision made by commission fol-
    lowing public hearing at which untruthful representa-
    tions were allegedly made by interested party and opin-
    ing that ‘‘misconduct or conflict of interest by members
    of the board’’ may, alternatively, ‘‘rise to the level of a
    public policy violation sufficient to support a collateral
    attack’’).
    Here, the plaintiffs contend that the variance would
    undermine the ‘‘best interests of the town’’ of Vernon
    (town). According to the plaintiffs, by adopting its zon-
    ing regulations, the town necessarily determined that
    the allowance of multiple liquor stores within 3000 feet
    of one another would be ‘‘contrary to the best interests
    of the town.’’ Further, the plaintiffs assert that, if Toor
    were to open a liquor store on the property, the new
    store would ‘‘establish a new 3000 foot [separating dis-
    tance] and burden’’ other preexisting properties. ‘‘The
    applicant’s variance, [according to the plaintiffs] will
    preclude liquor stores from being located within
    roughly one-half mile of [the] new store.’’ We find the
    plaintiffs’ arguments unavailing.
    The plaintiffs’ contention that the variance violates
    public policy because it varies the zoning regulations
    is not persuasive because it is entirely circular. By defi-
    nition, ‘‘[a] variance constitutes permission to act in a
    manner that is otherwise prohibited under the zoning
    law of the town.’’ (Internal quotation marks omitted.)
    Mayer-Wittmann v. Zoning Board of Appeals, 
    supra,
    333 Conn. 640
    . Accordingly, every variance granted by
    a zoning authority, under the plaintiffs’ argument, would
    constitute a violation of public policy sufficient to sup-
    port a collateral attack. See Caltabiano v. L & L Real
    Estate Holdings II, LLC, supra, 
    122 Conn. App. 762
    .
    Such a contention is foreclosed by logic and our existing
    jurisprudence.
    As we have acknowledged, nothing in the record sug-
    gests that the plaintiffs could not have expressed their
    concerns, including those concerns about the number
    of liquor stores in the town, before the board or on
    direct appeal. Furthermore, the record establishes that
    Boyajian expressed before the commission concerns
    about the number of liquor stores in the town to no avail.
    Because the continued maintenance of the underlying
    variance does not ‘‘violate some strong public policy’’;
    Upjohn Co. v. Zoning Board of Appeals, 
    supra,
     
    224 Conn. 105
    ; the plaintiffs may not collaterally attack the
    board’s decision to grant the variance under this excep-
    tion.
    The judgment is affirmed.
    In this opinion the other judges concurred.

    ally, we refer to Boyajian and JPB, LLC, by their respective names.

    Toor filed a motion to intervene in the underlying appeal to the Superior
    Court, which was granted. Toor has not participated in the present appeal.

    General Statutes § 8-8 (b) provides in relevant part: ‘‘[A]ny person
    aggrieved by any decision of a board . . . may take an appeal to the superior
    court for the judicial district in which the municipality is located . . . .
    The appeal shall be commenced by service of process . . . within fifteen
    days from the date that notice of the decision was published as required
    by the general statutes. . . .’’ The record demonstrates, and the plaintiffs
    concede, that notice of the board hearing concerning the variance was
    published in the Journal Inquirer on April 11, 2018. On April 18, 2018, the
    board granted the variance at the conclusion of the hearing and notified
    Toor the following day. The plaintiffs do not claim in this appeal that the
    board did not give proper notice to the public of its decision to grant
    the variance.
    5
    Boyajian did not identify himself as the owner of JPB, LLC, or the
    operator of Riley’s Liquor in his comments to the commission.
    6
    When he addressed the commission, Boyajian conceded on the record
    that the granting of the variance was appealable within the statutory period.
    7
    Board member Roland Klee noted after the conclusion of the hearing,
    ‘‘the variance is in effect, [it has] been recorded on the [l]and [r]ecords
    . . . .’’ Klee later moved to approve the special permit application ‘‘based
    on its compliance with the [s]pecial [p]ermit standards of [§] 17.3.1. [of the
    zoning regulations].’’
    8
    The plaintiffs raised as an additional ground for reversing the decision
    of the commission that the variance had lapsed because of Toor’s failure
    to make any substantial progress on the use in the year following the board’s
    decision. The trial court rejected this ground, finding the following: (1) ‘‘no
    party adduced evidence . . . relevant to’’ the claim; (2) Toor ‘‘expeditiously
    applied’’ for the special permit after the board approved the variance; and
    (3) because the plaintiffs appealed to the trial court just one month after
    the commission granted the special permit application, Toor was justified
    in delaying construction until after the resolution of the appeal. The plaintiffs
    have not raised this issue in the present appeal, and, accordingly, it is not
    properly before us.
    9
    The trial court considered and rejected the merits of the plaintiffs’ argu-
    ment that the variance was fundamentally void. As set forth subsequently
    in this opinion, we decline to consider the merits of this argument.
    10
    The plaintiffs argue that they properly appealed to the trial court the
    commission’s improper application of the zoning regulations and, thus, have
    valid grounds outside of the underlying variance. The plaintiffs contend
    that, because the commission did not apply the 3000 foot separating distance
    set forth in the zoning regulations, it ‘‘illegal[ly]’’ granted the special permit
    application. The plaintiffs’ arguments, however, inextricably recognize the
    alternative separating distance on which the commission relied in granting
    the special permit—the 2935 foot separating distance, as authorized by the
    board. Further, before the trial court, when asked whether the plaintiffs
    asserted any ‘‘claim that there was some other provision unrelated to the
    variance,’’ counsel for the plaintiffs answered, ‘‘[n]o. No traffic issue. Nothing
    like that, Your Honor.’’

    able.’’ American Institute for Neuro-Integrative Development, Inc. v. Town

    12
    No section of the zoning regulations expressly allows the commission
    to ignore a related variance, previously granted by the board, in considering
    an application for a special permit. Moreover, we note that our Superior
    Courts have suggested that planning and zoning commissions may not ignore
    related variances that directly bear on the applications before them. See,
    e.g., Scandia Construction & Development Corp. v. Planning & Zoning
    Commission, Superior Court, judicial district of Danbury, Docket No. CV-
    XX-XXXXXXX-S (November 16, 2001).

    In discussing the Upjohn Co. exceptions, our Supreme Court, in Torring-
    ton v. Zoning Commission, supra, 
    261 Conn. 768
    , noted that the Upjohn
    Co. exceptions were available ‘‘to the extent that a party seeks to attack
    collaterally a previously unchallenged zoning decision on the basis of the
    zoning authority’s lack of subject matter jurisdiction . . . .’’ (Emphasis
    added.) The plaintiffs in the present case make no claim that the board
    lacked subject matter jurisdiction to grant a variance. They simply argue
    that the commission should not have granted the special permit application,
    on the basis of the invalidity of the underlying variance. Although our case
    law is somewhat unclear as to whether the Upjohn Co. exceptions may
    apply to cases in which there is no attack as to subject matter jurisdiction
    of the prior tribunal, we nonetheless consider the exceptions here.
