    THE STRAND/BRC GROUP, LLC, ET AL. v.
    BOARD OF REPRESENTATIVES OF
    THE CITY OF STAMFORD
    (SC 20578)
    Robinson, C. J., and McDonald, D’Auria, Mullins,
    Kahn, Ecker and Keller, Js.*
    Syllabus
    Pursuant to the Stamford Charter (§ C6-30-7), ‘‘[i]f [20] percent or more of
    the owners of the privately-owned land in the area included in any
    proposed amendment to the Master Plan, or the owners of [20] percent
    or more of the privately-owned land located within [500] feet of the
    borders of such area, file a signed petition with the Planning Board . . .
    objecting to the proposed amendment, then said decision shall have no
    force or effect but the matter shall be referred by the Planning Board
    to the Board of Representatives . . . . The Board of Representatives
    shall approve or reject such proposed amendment at or before its second
    regularly-scheduled meeting following such referral.’’
    The plaintiffs, owners of certain real property in the city of Stamford,
    appealed to the trial court from the decision of the defendant board of
    representatives, which had rejected the decision of the city’s planning
    board to approve the plaintiffs’ application to amend the city’s master
    plan. In their application filed with the planning board, the plaintiffs
    sought an amendment to the master plan in order to modify the land
    use categories of their properties, which previously had been the site
    of a recycling center, to allow for high density residential development.
    The planning board then submitted its own application, seeking to mod-
    ify the land use categories of adjacent properties to allow for similar
    development. The planning board conducted separate hearings on the
    two applications and approved the amendments proposed therein by
    separate motions, reclassifying the relevant properties to allow for high
    density, multifamily residential development. Thereafter, an individual
    affiliated with a local neighborhood organization filed a single protest
    petition, signed by owners of property adjacent to the plaintiffs’ proper-
    ties, with the planning board pursuant to § C6-30-7, challenging the two
    amendments to the master plan approved by the planning board. The
    planning board referred the protest petition to the board of representa-
    tives pursuant to § C6-30-7, and a legislative officer for the board of
    representatives determined that the petition was valid as to the amend-
    ment pertaining to the adjacent properties because it met the signature
    requirement set forth in § C6-30-7 but that it was invalid as to the
    amendment pertaining to the plaintiffs’ properties because it did not
    meet the signature requirements for the subject area. Nonetheless, the
    board of representatives subsequently voted to verify the validity of the
    protest petition. The board of representatives then voted on the merits
    of the protest petition and rejected the planning board’s approval of
    the amendments to the master plan pertaining both to the plaintiffs’
    properties and the adjacent properties. On appeal from the decision of
    the board of representatives, the trial court concluded that the board
    of representatives did not have the authority to determine the validity
    of the protest petition because, once the petition was filed with the
    planning board, the charter charged the board of representatives only
    with determining the substantive issue of whether the proposed amend-
    ments should be approved or rejected. The court rendered judgment
    sustaining the plaintiffs’ administrative appeal, from which the board
    of representatives appealed. Held:
    1. The trial court correctly concluded that the board of representatives
    lacked authority to assess the validity of a protest petition that had
    been referred to it by the planning board: although the charter allows
    opponents of an amendment to the master plan to challenge the proposed
    amendment by filing a valid protest petition with the planning board,
    once the protest petition is referred to the board of representatives, the
    language of § C6-30-7 of the charter authorizes the board of representa-
    tives only to ‘‘approve or reject [the] proposed amendment’’ and not
    the protest petition itself, which is merely the procedural vehicle to
    put the amendment before the board of representatives for review;
    moreover, the charter provisions require the planning board to verify
    the procedural validity of a protest petition before referring that petition
    to the board of representatives; accordingly, the board of representatives
    acted outside of the powers granted to it by the charter and overstepped
    its authority by purporting to verify the validity of the protest petition
    referred to it by the planning board, and its vote on the validity of the
    protest petition was improper.
    2. The board of representatives could not prevail on its claim that, even if
    it did not have authority to decide the validity of the protest petition,
    it nonetheless properly exercised its authority under the charter to
    decide the merits of the plaintiffs’ application by rejecting the planning
    board’s amendment to the city’s master plan under the plaintiffs’ applica-
    tion, and, accordingly, the trial court properly sustained the plaintiffs’
    appeal: under § C6-30-7 of the charter, a protest petition is valid and
    subject to referral by the planning board only if it is timely filed and
    signed by either 20 percent or more of the owners of the privately owned
    land in the area that is the subject of the proposed amendment to the
    master plan or signed by the owners of 20 percent or more of the
    privately owned land located within 500 feet of the borders of such
    area, and, because a valid protest petition is a condition precedent to
    the authority of the board of representatives to vote on the merits of
    an amendment, that board’s vote on the merits of an amendment con-
    tained in an invalid petition is void; moreover, the signature requirements
    in § C6-30-7 are not a mere formality but serve an important substantive
    purpose, namely, limiting the authority conferred on the board of repre-
    sentatives by ensuring that review of an amendment to the master plan
    by that board is triggered only if there is a sufficient number of owners
    of private property within a defined geographical area with interests
    directly affected by the proposed amendment, and, because those
    requirements were intended to be mandatory rather than directory, the
    board of representatives did not have discretion to act on the proposed
    amendment notwithstanding the legal invalidity of the protest petition;
    furthermore, this court previously had held that the signatures in a
    single protest petition challenging two distinct amendments cannot be
    aggregated to meet the threshold signature requirements set forth in
    § C6-30-7, and, in the present case, it was undisputed that, insofar as
    the protest petition challenged the amendment approved in the plaintiffs’
    application, the petition did not contain the threshold number of signa-
    tures required to permit the planning board to refer the petition to the
    board of representatives.

    Procedural History
    Appeal from the decision of the defendant rejecting
    a decision by the Planning Board of the City of Stamford
    to amend the city’s master plan to permit certain resi-
    dential development, brought to the Superior Court in
    the judicial district of Stamford-Norwalk and trans-
    ferred to the judicial district of Hartford, Land Use
    Litigation Docket, where the case was tried to the court,
    Hon. Marshall K. Berger, Jr., judge trial referee, who,
    exercising the powers of the Superior Court, rendered
    judgment sustaining the appeal, from which the defen-
    dant, on the granting of certification, appealed. Affirmed.
    Patricia C. Sullivan, for the appellant (defendant).
    David T. Martin, for the appellees (plaintiffs).
    Opinion
    ECKER, J. The dispositive issue in this appeal is
    whether the defendant, the Board of Representatives
    of the City of Stamford (board of representatives), had
    the authority to approve a protest petition that objected
    to master plan amendments approved by the Planning
    Board of the City of Stamford (planning board). The
    plaintiffs, The Strand/BRC Group, LLC, 5-9 Woodland,
    LLC, Woodland Pacific, LLC, and Walter Wheeler Drive
    SPE, LLC, filed an application with the planning board
    to amend the master plan of the city of Stamford (city).
    Shortly afterward, the planning board filed its own
    application to amend the city’s master plan. After the
    planning board approved both applications with some
    modifications, local property owners filed a protest
    petition under § C6-30-7 of the Stamford Charter (char-
    ter). The board of representatives determined that the
    protest petition was valid and rejected the planning
    board’s approval of the amendments. The plaintiffs
    appealed from the decision of the board of representa-
    tives to the trial court, which sustained the plaintiffs’
    appeal. We affirm the judgment of the trial court.
    The underlying facts are undisputed. The plaintiffs
    own parcels of real property in the city located at 707
    Pacific Street; 5, 9, 17, 21, 23, 25, 29, 39 and 41 Woodland
    Avenue; and 796 Atlantic Street. In October, 2018, the
    plaintiffs proposed an amendment to the city’s master
    plan to modify their properties’ land use categories
    (Application MP-432) to allow high density residential
    development on the site, which previously had been
    used as a recycling collection and disposal center. Spe-
    cifically, the plaintiffs sought to modify their properties’
    land use categories from category 4 (residential—
    medium density multifamily), category 6 (commer-
    cial—neighborhood), and category 9 (urban mixed-
    use), to category 5 (residential—high density multifam-
    ily) and category 9, which would allow for more dense
    development. The planning board thereafter submitted
    its own application to modify the land use categories
    of adjacent properties from categories 4 and 6 to cate-
    gory 9 (Application MP-433).1 The proposals contained
    in the respective applications, though plainly related,
    were two different amendments contained in two differ-
    ent applications from two different applicants. Applica-
    tion MP-432 was filed separately from Application MP-
    433 and advertised to the public independently. The
    planning board conducted public hearings on both
    applications, after which it approved them by separate
    motions insofar as they each sought a change to land
    use category 5.2 The planning board published separate
    legal notices of the approval of each amendment.
    Shortly thereafter, Susan Halpern, vice president of
    the South End Neighborhood Revitalization Zone Initia-
    tive, filed a single protest petition signed by adjacent
    property owners, challenging the planning board’s
    approval of Applications MP-432 and MP-433 pursuant
    to § C6-30-7 of the charter, which provides in relevant
    part that, ‘‘[i]f twenty (20) percent or more of the owners
    of the privately-owned land in the area included in any
    proposed amendment to the Master Plan, or the owners
    of twenty (20) percent or more of the privately-owned
    land located within five hundred (500) feet of the bor-
    ders of such area, file a signed petition with the Planning
    Board within ten days after the official publication of
    the decision thereon, objecting to the proposed amend-
    ment, then said decision shall have no force or effect
    but the matter shall be referred by the Planning Board
    to the Board of Representatives within twenty days
    after such official publication, together with written
    findings, recommendations and reasons. The Board of
    Representatives shall approve or reject such proposed
    amendment at or before its second regularly-scheduled
    meeting following such referral. . . .’’ Pursuant to § C6-
    30-21 of the charter, the decision must be made by an
    ‘‘affirmative vote of a majority of the entire membership
    of said Board . . . .’’ See generally Benenson v. Board
    of Representatives, 
    223 Conn. 777
    , 781, 
    612 A.2d 50
    (1992) (describing protest petition process).
    Pursuant to § C6-30-7, the planning board referred
    the protest petition to the forty member board of repre-
    sentatives on the same day it was received. The legisla-
    tive officer, Valerie T. Rosenson, for the board of repre-
    sentatives reviewed the validity of the protest petition
    and determined that it was valid as to Application MP-
    433 because it had been signed by 33 percent of the
    property owners in the subject area relevant to Applica-
    tion MP-433 but invalid as to Application MP-432
    because it had not been signed by 20 percent of the
    property owners in the 500 foot border of the area or
    20 percent of the property owners in the subject area
    relevant to Application MP-432.3
    Approximately ten days later, the city’s special coun-
    sel, James Minor, submitted a memorandum, recom-
    mending that the board of representatives separately
    address each of the two applications referenced in the
    protest petition because the applications ‘‘involved sep-
    arate applicants, application numbers, property bound-
    aries, amendments, legal notices and decisions.’’ Addi-
    tionally, Attorney Minor pointed out that, pursuant to
    Stamford Ridgeway Associates v. Board of Representa-
    tives, 
    214 Conn. 407
    , 
    572 A.2d 951
     (1990), and Hanover

    ,

    ,
    cert. granted, 
    194 Conn. 805
    , 
    482 A.2d 710
     (1984) (appeal
    dismissed March 5, 1985), the board of representatives
    must determine if it has authority to consider the protest
    petition by ascertaining whether it contains a sufficient
    number of signatures on the basis of ‘‘the area where
    the specific amendment is located,’’ as opposed to the
    area that may be affected by the change.
    The issue concerning the validity of the protest peti-
    tion was referred to the board of representative’s land
    use-urban redevelopment committee (committee), which
    voted unanimously to reject the protest petition with
    respect to Application MP-432 and to accept the protest
    petition with respect to Application MP-433. Following
    a public hearing, at which various property owners
    expressed their disapproval of both amendments, the
    board of representatives voted to send Application MP-
    432 back to the committee for reconsideration. The
    committee reconsidered its decision to reject Applica-
    tion MP-432 and ultimately approved the protest peti-
    tion as it applied to Application MP-432. On the same
    day, the board of representatives convened a special
    meeting to determine the validity of the protest petition,
    at which it voted to verify its validity by a vote of seven-
    teen to twelve. The board of representatives later voted
    on the merits of the protest petition and rejected the
    planning board’s approval of Application MP-432 by a
    vote of twenty-one to eleven and Application MP-433
    by a vote of twenty-three to twelve.
    The plaintiffs appealed to the trial court from the
    rejection of Application MP-432 by the board of repre-
    sentatives.4 The plaintiffs challenged the authority of
    the board of representatives to review the planning
    board’s decision on numerous grounds, and the parties
    agreed to address that issue as a threshold matter before
    reaching the merits. Pursuant to Benenson v. Board of
    Representatives, supra, 
    223 Conn. 777
    , the trial court
    determined that ‘‘the board [of representatives] had no
    authority to determine the validity of the petition and
    [that] its action was improper’’ because, ‘‘[o]nce the
    petition was filed with the planning board, the only
    charge for the board [of representatives] was to deter-
    mine the substantive issue, i.e., the proposed amend-
    ments.’’ The court then determined that, even if the
    board of representatives had the authority to vote on
    the validity of the protest petition, ‘‘[t]he vote was not
    sufficient [because] it failed to garner a majority of the
    entire forty person board or twenty-one votes.’’5 See
    Stamford Charter § C6-30-21 (requiring majority vote of
    entire board of representatives ‘‘in deciding all mat-
    ters’’). Accordingly, the trial court sustained the plain-
    tiffs’ appeal. This appeal followed.6
    On appeal, the board of representatives claims that,
    regardless of whether it lacked authority to decide the
    validity of the protest petition, it nonetheless had
    authority to rule on the merits of Application MP-432,
    which was duly rejected by a majority of that board,
    i.e., twenty-one members. The plaintiffs respond that
    the board of representatives lacked authority to rule
    on the merits of Application MP-432 because the charter
    does not authorize that board to vote on the validity of
    a protest petition, and, in the absence of a valid petition,
    the board of representatives lacked the authority to
    reach the merits of the application. Relatedly, the plain-
    tiffs argue that the protest petition was invalid because
    it lacked the requisite number of signatures to trigger
    referral by the planning board under the charter and,
    accordingly, that there was ‘‘no procedural vehicle to
    put the amendment before the board [of representa-
    tives] for review.’’ Alternatively, if the board of repre-
    sentatives had the authority to vote on the validity of
    the protest petition, the plaintiffs contend that its
    approval of the protest petition by a vote of seventeen
    to twelve was invalid because the petition required an
    affirmative vote of twenty-one board members.
    The board of representatives, in considering the pro-
    posed amendment, was ‘‘called [on] to perform a legisla-
    tive function.’’ (Internal quotation marks omitted.)

    , 39, 
    166 A.2d 849
     (1961). Because the board of representatives was
    acting in a legislative capacity, the decision of the board
    ‘‘must not be disturbed by the courts unless the party
    aggrieved by that decision establishes that the [board]
    acted arbitrarily or illegally.’’ (Internal quotation marks

    We first address whether, pursuant to the charter,
    the board of representatives has the authority to assess
    the validity of a protest petition that has been referred
    by the planning board. ‘‘[I]n interpreting [charter] lan-
    guage . . . we do not write on a clean slate, but are
    bound by our previous judicial interpretations of this
    language and the purpose of the [charter provisions].’’

    312 Conn. 513
    , 527, 
    93 A.3d 1142
     (2014). In Benenson
    v. Board of Representatives, 
    supra,
     
    223 Conn. 777
    , this
    court addressed the board of representatives’ authority
    to review a protest petition under a former provision,
    § C-552.2,8 of the charter. Section C-552.2 provided in
    relevant part that, if a valid petition is filed ‘‘with the
    zoning board . . . objecting to the proposed amend-
    ment, said decision shall have no force or effect but
    the matter shall be referred by the zoning board to
    the board of representatives . . . together with written
    findings, recommendations and reasons. The board of
    representatives shall approve or reject such proposed
    amendment at or before its second regularly scheduled
    meeting following such referral.’’ (Internal quotation
    marks omitted.) Id., 780 n.3. On the basis of the plain
    language of § C-552.2, we concluded that ‘‘[t]he question
    before the board [of representatives] was not the peti-
    tion, which indicated the property owners’ objection to
    the zone change, but whether the zone change should
    be approved. The petition was merely the vehicle that
    brought the issue before [said] board. This is made clear
    in § C-552.2, which provides that after the petition is
    referred to the board [of representatives, it] shall
    approve or reject such proposed amendment . . . .
    The charter does not provide for the approval or rejec-
    tion of the petition itself.’’ (Emphasis altered; internal
    quotation marks omitted.) Id., 783; see Burke v. Board
    of Representatives, 
    supra,
     
    148 Conn. 39
     (‘‘The manifest
    legislative intent expressed in the . . . charter is that
    the board of representatives, in considering an amend-
    ment to the zoning map, shall review the legislative
    action of the zoning board on [its] written findings,
    recommendations and reasons. The question before the
    board of representatives is whether to approve or to
    reject the amendment.’’).
    The relevant charter provision at issue in this appeal
    is essentially the same as the charter provision that we
    interpreted in Benenson. Both § C-552.2 and § C6-30-7
    allow opponents of an amendment to the zoning plan
    or the master plan of the city, respectively, to challenge
    the proposed amendment by filing a valid protest peti-
    tion with the zoning board or the planning board, as
    the case may be. Once the protest petition has been
    referred to the board of representatives, the language
    of § C6-30-7, like the language of § C-552.2, authorizes
    only that the board of representatives approve or reject
    the amendment, not ‘‘the ‘petition’ itself.’’ (Emphasis
    added.) Benenson v. Board of Representatives, 
    supra,
    223 Conn. 783
    ; see Stamford Charter § C6-30-7 (‘‘[The
    protest petition] shall be referred by the Planning Board
    to the Board of Representatives within twenty days after
    . . . official publication, together with written findings,
    recommendations and reasons. The Board of Represen-
    tatives shall approve or reject such proposed amend-
    ment at or before its second regularly-scheduled meet-
    ing following such referral.’’). Thus, the board of
    representatives lacks the authority to assess the validity
    of a protest petition after it has been duly referred by
    the planning board.
    As the trial court pointed out, ‘‘this leaves the ques-
    tion of who had authority to determine the validity of
    the petition . . . .’’ Our review of the charter leads us
    to conclude that its provisions require the planning
    board to verify the procedural validity of a protest peti-
    tion before it refers the petition to the board of represen-
    tatives. Section C6-30-7 provides that the planning
    board ‘‘shall’’ refer a protest petition to the board of
    representatives only if two requirements are met: (1) the
    petition is signed by the requisite number of property
    owners in the subject area, and (2) the petition is filed
    with the planning board within ten days after the official
    publication of the planning board’s decision.9 Once a
    protest petition has been referred, the authority of the
    board of representatives is limited to either ‘‘approv[-
    ing] or reject[ing]’’ the proposed amendment. Stamford
    Charter § C6-30-7. Thus, the board of representatives
    overstepped its authority by purporting to verify the
    validity of the protest petition.
    It is well established that municipal authorities are
    ‘‘confined to the circumference of those [powers]
    granted and may not travel beyond the scope of [the]
    charter or in excess of the granted authority.’’ (Internal
    quotation marks omitted.) Highgate Condominium

     (1989). ‘‘[When] the town charter pre-

    supra,
     
    148 Conn. 42
     (‘‘[when] the charter of a municipal-
    ity provides that action of the legislative body shall be
    by ordinance or resolution, it must act in the manner
    prescribed’’); Food, Beverage & Express Drivers Local

     (1960) (charter is city’s enabling act, and, ‘‘[when]
    the charter points out a particular way in which any
    act is to be done, the prescribed form must be pursued
    for the act to be lawful’’). Because the board of repre-
    sentatives was acting outside of the powers granted by
    the charter, we conclude that its vote on the validity
    of the protest petition was improper.10
    II
    The board of representatives contends that, regard-
    less of whether it had the authority to decide the validity
    of the protest petition, it plainly had the authority to
    decide the merits of Application MP-432, which is
    exactly what it did when a majority voted to reject the
    planning board’s amendment to the city’s master plan
    under Application MP-432. It argues that its vote on the
    validity of the protest petition was at worst ‘‘a nullity’’
    that must be ‘‘ignored’’ and, therefore, that the trial
    court improperly failed to address the substantive issue
    of whether the board of representatives properly
    rejected Application MP-432 on the merits. The claim,
    in essence, is ‘‘no harm, no foul’’—the board of repre-
    sentatives had authority under the charter to approve
    the protest petition, and it did so by majority vote.
    This argument might well be persuasive if the protest
    petition at issue, as it relates to Application MP-432,
    had been a legally valid petition pursuant to the charter.
    But, for reasons we discuss next, the petition protesting
    the amendment approved under Application MP-432
    was invalid as a matter of law, and the board of repre-
    sentatives’ approval of that invalid petition cannot be
    sustained as a result.
    Section C6-30-7 of the charter authorizes the planning
    board to refer a protest petition to the board of repre-
    sentatives only if it is timely filed and signed by (1)
    ‘‘twenty (20) percent or more of the owners of the
    privately-owned land in the area included in any pro-
    posed amendment to the Master Plan,’’ or (2) ‘‘the own-
    ers of twenty (20) percent or more of the privately-
    owned land located within five hundred (500) feet of
    the borders of such area . . . .’’ The planning board
    has twenty days to refer the protest petition to the board
    of representatives, which then must either ‘‘approve or
    reject such proposed amendment . . . .’’ Stamford
    Charter § C6-30-7; see Benenson v. Board of Represen-
    tatives, 
    supra,
     
    223 Conn. 783
    . The failure of the board of
    representatives to timely approve or reject the proposed
    amendment is ‘‘deemed as approval of the Planning
    Board’s decision.’’ Stamford Charter § C6-30-7.
    The signature requirement set forth in the charter
    serves an obvious and important purpose. The board
    of representatives cannot exercise its authority to
    accept or reject a proposed amendment to the master
    plan at will. See Stamford Ridgeway Associates v.
    Board of Representatives, 
    supra,
     
    214 Conn. 424
     (noting
    that petition requirements of analogous charter provi-
    sion governing protest petition for zoning map amend-
    ments determines ‘‘authority of the board of representa-
    tives’’ to accept or reject proposed change). Instead,
    § C6-30-7 confers a limited authority on the board of
    representatives, which may be exercised only if a suffi-
    cient percentage of the owners of private property
    within a defined geographical area—an area in or proxi-
    mate to the affected area—sign and timely file a protest
    petition with the planning board.11 See id., 413. The
    language of the charter seeks ‘‘to provide affected land-
    owners a right to appeal a proposed [amendment]’’ by
    requesting reconsideration by the board of representa-
    tives after a threshold requirement has been met.
    (Emphasis added.) Id., 432; see Steiner, Inc. v. Town
    Plan & Zoning Commission, 
    149 Conn. 74
    , 76, 
    175 A.2d 559
     (1961) (protest petitions are designed ‘‘to afford
    protection to [nearby] property owners against changes
    to which they object’’); Warren v. Borawski, 
    130 Conn. 676
    , 681, 
    37 A.2d 364
     (1944) (observing that ‘‘[t]he pur-
    pose of [a New Britain ordinance permitting the town
    council to vote on a proposed zoning amendment] if a
    protest is filed by owners of 20 [percent] of the property
    affected is to give some protection to those owners
    against changes to which they object’’ (emphasis
    added)). The signature requirement is not a mere for-
    mality but a substantive provision of the charter
    intended to ensure that review by the board of represen-
    tatives is triggered if, and only if, there is a sufficient
    number of owners of private land with interests directly
    affected by the proposed amendment. See Stamford
    Ridgeway Associates v. Board of Representatives,
    
    supra, 426
     (construing analogous charter provision gov-
    erning protest petitions for zoning amendments to pre-
    vent improper procedures from frustrating purpose of
    provision to serve interests of owners of private land
    most affected by amendments).12
    To give § C6-30-7 its intended and obvious meaning,
    it is clear that a protest petition is valid and subject to
    referral by the planning board only if it contains the
    required number of signatures. See id., 413 (explaining
    that sufficient signatures are needed for board of repre-
    sentatives to reconsider amendment);13 Burke v. Board
    of Representatives, 
    supra,
     
    148 Conn. 35
     (explaining that
    referral is made ‘‘[i]n th[e] event’’ that protest petition
    meets signature requirements); see also Blaker v. Plan-
    ning & Zoning Commission, 
    219 Conn. 139
    , 148, 
    592 A.2d 155
     (1991) (‘‘[a] protest petition is not presump-
    tively valid’’).14 In the absence of the required number
    of signatures, a protest petition cannot properly be
    referred to the board of representatives, and, therefore,
    that board cannot properly reach the merits of the
    amendment challenged by the protest petition. See Wol-
    dan v. Stamford, 
    22 Conn. Supp. 164
    , 167, 
    164 A.2d 306
    (1960) (concluding that ‘‘the petition did not contain
    the signatures of owners of 20 [percent] of the land
    within 500 feet,’’ as required by charter, and, therefore,
    ‘‘the matter was not properly before the board of repre-
    sentatives’’). Because a valid protest petition is a condi-
    tion precedent to the authority of the board of represen-
    tatives to vote on the merits of an amendment, that
    board’s vote on the merits of an amendment contained
    in an invalid petition is void.
    The dissent contends that the board of representa-
    tives, as a legislative body comprised of elected offi-
    cials, has discretion to act on the proposed amendment
    notwithstanding the legal invalidity of the protest peti-
    tion. This is so, the dissent argues, because the petition
    requirements set forth in the charter are merely ‘‘direc-
    tory’’ and nonsubstantive. We disagree. The board of
    representatives is entitled to discretion when acting in
    its legislative capacity, but it is not at liberty to act in
    contravention of charter provisions expressly limiting
    that authority to specified conditions. Nor are that
    board’s legislative actions insulated from judicial
    review when it has exceeded its authority under the
    express provisions of the charter. See Parks v. Plan-
    ning & Zoning Commission, 
    178 Conn. 657
    , 661, 
    425 A.2d 100
     (1979) (‘‘[t]he broad discretion of local [munic-
    ipal] authorities acting in their legislative capacity is
    not . . . unlimited’’); see also Stamford Charter § C2-
    10-1 (‘‘The legislative power of the City shall be vested
    in the Board of Representatives. No enumeration of
    powers contained in this Charter shall be deemed to
    limit the legislative power of the Board except as specif-
    ically provided in this Charter.’’ (Emphasis added.)).
    The distinction that our case law makes between
    ‘‘directory’’ and ‘‘mandatory’’ provisions in statutes or
    charters cannot avoid or render benign the charter vio-
    lation that occurred when the board of representatives
    acted on a proposed amendment that was not properly
    before it due to the legal defect in the protest petition.
    We have held that ‘‘[t]he test to be applied in determin-
    ing whether a statute is mandatory or directory is
    whether the prescribed mode of action is the essence
    of the thing to be accomplished, or in other words,
    whether it relates to a matter of substance or a matter
    of convenience. . . . If it is a matter of substance, the
    statutory provision is mandatory. If, however, the legis-
    lative provision is designed to secure order, system and
    dispatch in the proceedings, it is generally held to be
    directory, especially [when] the requirement is stated in
    affirmative terms unaccompanied by negative words.’’

    ‘‘Stated another way, language is deemed to be manda-
    tory if the mode of action is of the essence of the
    purpose to be accomplished by the statute . . . but
    will be considered directory if the failure to comply
    with the requirement does not compromise the purpose
    of the statute.’’ (Citation omitted.) Angelsea Produc-
    tions, Inc. v. Commission on Human Rights & Oppor-
    tunities,

     (1996).
    The express signature requirements in § C6-30-7 are
    elaborate in detail and crafted to achieve a manifestly
    substantive purpose. The charter specifies the precise
    numerical and geographical requirements that must be
    satisfied by the signatories before the protest petition
    can trigger referral of the proposed amendment to the
    board of representatives. These charter requirements
    are not imposed for ‘‘convenience and dispatch’’ or ‘‘to
    ensure the orderly review of amendments by the board
    of representatives,’’ as the dissent suggests. Instead, as
    we previously discussed, the purpose of the signature
    requirement is to limit the authority of the board of
    representatives to reject an amendment to the master
    plan, once approved by the planning board, to situa-
    tions in which a protest petition is signed by a signifi-
    cant percentage of the persons most affected by the
    amendment (i.e., 20 percent of the owners of privately
    owned land in the area included in the proposed amend-
    ment or located within 500 feet of the borders of
    such area).16
    The dissent is correct that the detailed requirements
    in § C6-30-7 governing protest petitions are not accom-
    panied by an explicit statement containing negative or
    prohibitory language, but negative or prohibitory lan-
    guage of this sort is not dispositive of our analysis,
    particularly when, as here, the substantive nature of
    the requirement is clear. See Blake v. Meyer, 
    145 Conn. 612
    , 616, 
    145 A.2d 584
     (1958) (‘‘[i]t is clear that the
    provision under consideration is mandatory, not merely
    directory, even in the absence of prohibitory or negative
    language’’). The absence of negative or prohibitory lan-
    guage, in short, does nothing to alter our conclusion
    that the signature requirements in § C6-30-7 of the char-
    ter serve an important substantive purpose and were
    intended to be mandatory rather than directory.
    This brings us to the merits of the plaintiffs’ core
    challenge to the validity of the protest petition, namely,
    that the petition challenging the amendment approved
    in Application MP-432 is legally invalid because it lacks
    the requisite number of signatures.17 The issue, properly
    framed, is easily resolved under our case law because
    it is undisputed that, insofar as the protest petition
    challenged Application MP-432, in particular, it did not
    contain the threshold number of signatures required to
    permit referral to the board of representatives.18 As the
    trial court noted, the record indicates that the protest
    petition was valid and subject to referral only if the
    two different amendments contained in the respective
    applications, Applications MP-432 and MP-433, are con-
    sidered collectively instead of separately. See footnote
    5 of this opinion.
    Our precedent has spoken on the board of representa-
    tives’ authority to simultaneously vote on multiple zon-
    ing amendments, whether contained in one or multiple
    applications, as challenged in a protest petition. In
    Stamford Ridgeway Associates v. Board of Representa-
    tives, 
    supra,
     
    214 Conn. 409
    , we addressed whether, pur-
    suant to a former provision of the charter, § C-552.2,
    the board of representatives has authority ‘‘to vote on
    separate zone changes [involving multiple amend-
    ments] contained in one zoning application or whether
    the board of representatives must act on the entire
    application,’’ even though the single application con-
    tained several distinct amendments. Section C-552.2,
    which included essentially the same relevant text as
    § C6-30-7, and was the same provision at issue in Benen-
    son; see footnote 8 of this opinion; provided that, ‘‘if
    twenty percent or more of the owners of the privately-
    owned land in the area included in any proposed
    amendment’’ or ‘‘owners of twenty percent or more of
    the privately-owned land located within five hundred
    feet of the borders of such area’’ timely file a signed
    petition objecting to the proposed amendment, the peti-
    tion shall be referred to the board of representatives.
    (Emphasis added; internal quotation marks omitted.)
    Stamford Ridgeway Associates v. Board of Representa-
    tives, 
    supra,
     409 n.1; cf. Stamford Charter § C6-30-7
    (requiring, among other things, signatures from ‘‘twenty
    (20) percent or more of the owners of the privately-
    owned land in the area included in any proposed
    amendment’’ (emphasis added)). Because the word
    ‘‘amendment’’ has been ‘‘interpreted . . . as effecting
    a change in existing law,’’ we reasoned in Stamford
    Ridgeway Associates ‘‘that the [20] percent requirement
    in § C-552.2 is to be measured by the areas that were
    changed or rezoned’’ in connection with each individual
    amendment, rather than all the areas contained in the
    entire application. (Internal quotation marks omitted.)
    Stamford Ridgeway Associates v. Board of Representa-
    tives, 
    supra,
     425–26. We concluded that the board of
    representatives properly voted on ‘‘each separate zone
    change [amendment] within one application for which
    a valid protest petition has been filed.’’ Id., 436.
    Stamford Ridgeway Associates makes it clear that
    the relevant charter language requires the board of
    representatives considering a protest petition to treat
    each amendment individually instead of aggregating
    multiple amendments and voting on them collectively.
    ‘‘If we were to construe ‘amendment’ in § C-552.2 to
    mean . . . [all amendments in] the entire application
    . . . it would lead to bizarre and irrational results and
    frustrate the purpose of the charter provision’’ by
    enabling ‘‘a municipal agency to [e]nsure passage of
    a highly objectionable zoning amendment by simply
    combining it with another large, unobjectionable
    amendment. A statute must not be construed in a man-
    ner that would permit its purpose to be defeated.’’
    (Internal quotation marks omitted.) Id., 426. Further-
    more, ‘‘the use of the singular form of the word ‘amend-
    ment’ shows an intent to refer to only one amendment
    or one single zone change.’’ Id., 430. In light of the plain
    language and purpose of the charter, we held that the
    board of representatives properly ‘‘vote[d] on each sep-
    arate zone change encompassed in [one single] applica-
    tion . . . .’’ Id., 433.
    Pursuant to Stamford Ridgeway Associates, the sig-
    natures on a protest petition challenging two distinct
    amendments, contained, respectively, in Applications
    MP-432 and MP-433, cannot be aggregated to meet the
    threshold 20 percent requirements under § C6-30-7 of
    the charter. Because it is undisputed that Application
    MP-432, standing alone, lacked sufficient signatures to
    warrant referral to the board of representatives under
    the charter, we conclude that the protest petition was
    invalid as to Application MP-432. Accordingly, the board
    of representatives lacked the authority to vote on the
    merits of Application MP-432, and the trial court prop-
    erly sustained the plaintiffs’ appeal from that board’s
    decision.
    The judgment is affirmed.
    In this opinion ROBINSON, C. J., and McDONALD,
    MULLINS, KAHN and KELLER, Js., concurred.
    * This case originally was scheduled to be argued before a panel of this
    court consisting of Chief Justice Robinson and Justices McDonald, D’Auria,
    Mullins, Kahn, Ecker and Keller. Although Justice Ecker was not present
    when the case was argued before the court, he has read the briefs and
    appendices, and has listened to a recording of oral argument prior to partici-
    pating in this decision.

    The planning board concluded that category 9 was ‘‘too intense for this
    area . . . .’’ Accordingly, ‘‘instead of . . . categor[ies] 5 and 9 for the par-
    cels requested, the [planning] board adopted . . . category 5 for all of the
    parcels and rejected the request . . . [for] category 9.’’
    3
    According to Rosenson, only 6.77 percent of the property owners in the
    500 foot border area, and none of the property owners in the subject area
    of Application MP-432, signed the petition.
    4
    Neither the plaintiffs nor the planning board appealed from the decision
    of the board of representatives rejecting Application MP-433. Therefore,
    that board’s decision on Application MP-433 was not before the trial court
    and is not at issue in the present appeal.
    5
    Accordingly, the trial court determined that it was ‘‘unnecessary . . .
    to reach the issue of whether the protest petition, as applied to the plaintiffs’
    application, was invalid because it did not have the required signatures.’’
    Nonetheless, the trial court observed that ‘‘the record clearly indicates that
    . . . the board [of representatives] ignored the advice of its able counsel
    . . . and improperly counted the signatures [on] the protest petition and
    applied them to the plaintiffs’ and the planning board’s applications in
    combination instead of to each application separately.’’ (Citations omitted.)
    6
    The board of representatives appealed from the judgment of the trial
    court to the Appellate Court, which granted that board’s petition for certifica-
    tion to appeal pursuant to General Statute § 8-8 (o). We transferred the
    appeal to this court pursuant to General Statutes § 51-199 (c) and Practice
    Book § 65-1.

    The dissent contends that we do ‘‘not engage with or follow [the] reason-
    ing’’ of the case law governing judicial review of legislative action, citing
    LaTorre v. Hartford, 
    167 Conn. 1
    , 
    355 A.2d 101
     (1974), and Mills v. Town
    Plan & Zoning Commission, 
    145 Conn. 237
    , 
    140 A.2d 871
     (1958), overruled
    in part on other grounds by Mott’s Realty Corp. v. Town Plan & Zoning
    Commission, 
    152 Conn. 535
    , 
    209 A.2d 179
     (1965). Neither LaTorre nor Mills
    required this court to examine the scope of a municipal body’s authority
    to act under an applicable charter provision. The pertinent cases, cited in
    the body of this opinion, establish that (1) the proper inquiry in the present
    context is whether the board of representatives acted arbitrarily or illegally,
    and (2) under that standard, an action of the board of representatives is
    ‘‘illegal’’ if undertaken in violation of the requirements of the municipal char-
    ter.

    ‘‘Section C-552.2 of the . . . charter provide[d]: ‘After the effective date
    of the master plan, if the owners of twenty per cent or more of the privately-

    map, or if the owners of twenty per cent or more of the privately-owned
    land located within five hundred feet of the borders of such area, file a
    signed petition with the zoning board, within ten days after the official
    publication of the decision thereon, objecting to the proposed amendment,
    said decision shall have no force or effect but the matter shall be referred
    by the zoning board to the board of representatives within twenty days after
    such official publication, together with written findings, recommendations
    and reasons. The board of representatives shall approve or reject such
    proposed amendment at or before its second regularly scheduled meeting
    following such referral. When acting upon such matters the board of repre-
    sentatives shall be guided by the same standards as are prescribed for
    the zoning board in section 550 of this act. The failure of the board of
    representatives either to approve or reject said amendment within the above
    time limit shall be deemed as approval of the zoning board’s decision.’ ’’

    Because the planning board referred the protest petition to the board
    of representatives, we need not address the rules and procedures that would
    govern any appeal from the planning board’s refusal to refer a protest petition
    to the board of representatives.
    10
    In light of our conclusion, we need not address whether the board of
    representatives’ approval of the validity of the petition by a vote of seventeen
    to twelve was an ‘‘affirmative vote of a majority of the entire membership
    of [that] [b]oard’’ under § C6-30-21 of the charter.
    11
    The dissent criticizes our reliance on Stamford Ridgeway Associates,
    contending that ‘‘[i]t was not this court that said that [sufficient signatures
    in a protest petition are required to trigger review by the board of representa-
    tives]. Rather, that came from an opinion by Attorney Robert A. Fuller . . . .
    ’’ Footnote 6 of the dissenting opinion. The dissent ignores that we expressly
    relied on Fuller’s analysis to reach our conclusion that the ‘‘charter permits
    the board of representatives to vote on separate zone changes contained
    in one zoning application’’ if there are sufficient signatures with respect to
    each separate zone. Stamford Ridgeway Associates v. Board of Representa-
    tives, 
    supra,
     
    214 Conn. 409
    . We quoted Fuller at length and stated that ‘‘we
    agree with the parties that Fuller’s analysis . . . presents the most reason-
    able and rational interpretation’’ of the charter and ‘‘strikes a balance
    between the common good and public interest in zoning, and the legitimate
    private interest of property owners adversely affected by a proposed
    change.’’ (Internal quotation marks omitted.) 
    Id.,
     436–37. In light of this
    explicit adoption of Fuller’s analysis, we reject the dissent’s suggestion that
    we have misinterpreted Stamford Ridgeway Associates.
    12
    The dissent observes, and we agree, that an amendment to the master
    plan may affect ‘‘the interests of innumerable Stamford residents on issues
    of economics, environment, and population density, to name but a few.’’
    Footnote 5 of the dissenting opinion. But this court does not get to determine
    which Stamford residents are sufficiently affected by a proposed amendment
    to be eligible to sign the protest petition that would authorize the board of
    representatives to accept or reject the amendment. The charter makes that
    determination, and the relevant charter provision very clearly does not
    provide all Stamford residents with a right to protest the decision of the
    planning board to the board of representatives. Under the plain language
    of § C6-30-7, that right is limited to a specific percentage of owners of
    privately owned land within a defined geographic proximity of the ‘‘the area
    included in any proposed amendment’’ or ‘‘within five hundred (500) feet
    of the borders of such area . . . .’’
    13
    The dissent contends that ‘‘Stamford Ridgeway Associates makes clear
    that the signature provision is not an aggrievement, condition precedent,
    or limitation provision. Rather, it protects affected landowners nearby by
    empowering them to obtain greater review by the board of representatives,
    not less,’’ and that ‘‘[i]t cannot, therefore, be said that the signature provision
    is a matter of substance or that the full legislative scheme evinces an intent
    to impose a mandatory requirement.’’ (Footnote omitted.) The basis for this
    contention eludes us. Stamford Ridgeway Associates involved valid protest
    petitions signed by the requisite number of ‘‘owners of property . . . who
    were adversely affected by the proposed rezoning.’’ Stamford Ridgeway
    Associates v. Board of Representatives, 
    supra,
     
    214 Conn. 410
    . The problem
    was that multiple zone changes had been combined into a single zoning
    application, and, even though the protest petitions were valid as to each
    individual zone change, they were invalid as to the application as a whole.
    The issue on appeal was whether the signature requirement pertained to
    each individual zone change or to the whole application. See id., 409. To
    resolve that issue, we analyzed the purpose of the signature requirement
    and the function that it was intended to serve. We concluded that the
    signature provision serves an important substantive purpose and that con-
    struing it in such a manner as to apply to the application as a whole ‘‘would,
    as a practical matter . . . completely [frustrate]’’ that purpose. Id., 426. We
    relied on the opinion rendered by the board’s independent counsel, Attorney
    Robert A. Fuller, to conclude that, ‘‘[i]f a large percentage of the area included
    in the application was not proposed for a zone change (for example, the
    entire city of Stamford) . . . it would be impossible to obtain enough signa-
    tures to meet the [20] percent requirement within the ten day limitation
    [period] set by the charter to petition the board. Moreover, the property
    owners who were not affected by any of the zone changes or amendments
    or those who are comfortable with their zone change will be very reluctant
    [to sign] a petition.’’ (Internal quotation marks omitted.) Id.; see footnote
    11 of this opinion.
    Inherent in our holding in Stamford Ridgeway Associates was our conclu-
    sion that a protest petition must contain ‘‘enough signatures to meet the
    [20] percent requirement’’ and that, if there were an insufficient number of
    signatures, the signatories would have no ‘‘right to appeal to the board’’ of
    representatives. (Internal quotation marks omitted.) Stamford Ridgeway
    Associates v. Board of Representatives, 
    supra,
     
    214 Conn. 426
    . The dissent
    is correct, of course, that the signature provision protects affected, nearby
    owners of land by ‘‘empowering them to obtain greater review by the board
    of representatives,’’ but this is true only if the requisite number of those
    owners sign the petition. Any other reading of the charter renders those
    requirements meaningless.
    14
    Contrary to the dissent’s assertion, our holding in Burke does not support
    its thesis. In Burke, we addressed whether ‘‘the board of representatives
    act[ed] arbitrarily and illegally in failing to give notice and to provide a
    hearing before taking action to reject [a zoning] amendment . . . .’’ Burke
    v. Board of Representatives, 
    supra,
     
    148 Conn. 37
    . We answered that question
    in the negative because there were ‘‘no specific provisions for notice and
    hearing by the board of representatives, and we cannot write such provisions
    into the charter by judicial fiat.’’ Id., 40. In contrast, in the present case,
    there is a specific provision in the charter, providing for referral to the
    board if ‘‘twenty (20) percent or more of the owners of the privately-owned
    land in the area included in any proposed amendment to the Master Plan,
    or the owners of twenty (20) percent or more of the privately-owned land
    located within five hundred (500) feet of the borders of such area, file a
    signed petition with the Planning Board within ten days after the official
    publication of the decision thereon, objecting to the proposed amendment
    . . . .’’ Stamford Charter § C6-30-7. We cannot erase this explicit provision
    from the charter by judicial fiat any more than we can write some other
    provision into the charter. See Burke v. Board of Representatives, 
    supra, 40
    ; see also Kiewlen v. Meriden, supra, 
    317 Conn. 151
     n.11 (‘‘we are not at
    liberty to ignore the plain language of’’ municipal charter).
    15
    Our prior case law has looked at a number of factors to determine
    whether the provision can be deemed mandatory or directory. ‘‘These
    include: (1) whether the statute expressly invalidates actions that fail to
    comply with its requirements or, in the alternative, whether the statute by
    its terms imposes a different penalty; (2) whether the requirement is stated
    in affirmative terms, unaccompanied by negative language; (3) whether the
    requirement at issue relates to a matter of substance or one of convenience;
    (4) whether the legislative history, the circumstances surrounding the stat-
    ute’s enactment and amendment, and the full legislative scheme evince
    an intent to impose a mandatory requirement; (5) whether holding the
    requirement to be mandatory would result in an unjust windfall for the party
    seeking to enforce the duty or, in the alternative, whether holding it to be
    directory would deprive that party of any legal recourse; and (6) whether
    compliance is reasonably within the control of the party that bears the
    obligation, or whether the opposing party can stymie such compliance.’’

    In this respect, the petition requirements in § C6-30-7 stand in stark
    contrast to those provisions deemed directory by courts, which often involve
    time limitations set forth in specific statutory provisions designed to ensure
    order and convenience. See, e.g., United Illuminating Co. v. New Haven,

    decide appeal within sixty days after hearing is directory). See generally

    314 Conn. 749
    , 761, 
    104 A.3d 713
     (2014) (observing that, ‘‘in a number of cases,
    both this court and the Appellate Court have concluded that such statutory
    deadlines are directory [when] there is no express legislative guidance to
    the contrary and no indication that the legislature intended the deadline to
    be jurisdictional’’). But see Vartuli v. Sotire, 
    192 Conn. 353
    , 359, 
    472 A.2d 336
     (1984) (requirement to issue decision within sixty-five day limit is manda-
    tory), overruled by Leo Fedus & Sons Construction Co. v. Zoning Board

    that planning and zoning commission act on subdivision application within
    time limits is mandatory).
    The dissent incorrectly relies on these cases to support the notion that
    the relevant charter provision is directory. These cases, however, all involve
    time limitations, which often (although not always) are deemed directory
    in nature because the deadlines imposed do not implicate ‘‘the essence of
    the thing to be accomplished’’ but, rather, are ‘‘designed to secure order,
    system and dispatch in the proceedings . . . .’’ (Internal quotation marks
    omitted.) Meadowbrook Center, Inc. v. Buchman,

    328 Conn. 586
    , 
    181 A.3d 550
     (2018); see, e.g., 
    id.
    (‘‘[W]e are persuaded that the thirty day time provision set forth in Practice
    Book § 11-21 is intended to secure order and dispatch in the timely disposi-
    tion of a pending issue. Therefore, the time limitation contained in the rule
    is directory and not mandatory.’’); see also 3 S. Singer, Sutherland Statutes
    and Statutory Construction (8th Ed. 2020) § 57:17, pp. 101–102 (‘‘The question
    about whether time provisions are mandatory or directory . . . is a bit
    unique, as interpretation may be informed less by a search for legislative
    intent alone, and more by policy and equitable considerations aimed at
    avoiding harsh, unfair, or absurd consequences. . . . [F]or reasons founded
    in justice and fairness, and to avert injury to faultless parties, courts often
    find that such provisions are directory merely.’’ (Footnotes omitted.)).
    The signature requirements set forth in the charter, which define by
    geographical proximity those owners eligible to sign the protest petition
    and establish the minimum percentage of signatories needed to qualify for
    review, are not comparable to time limitations, which are intended to ensure
    order, efficiency and dispatch. Indeed, the dissent has not articulated any
    purpose for the signature requirements that could be considered nonsubstan-
    tive in nature.
    17
    During oral argument before this court, counsel for the board of repre-
    sentatives argued for the first time that the validity of the petition is not
    properly before us because the planning board is not a party to the present
    action and ‘‘the decision of the planning board [to refer a protest petition]
    would need to be appealed as any other land use appeal.’’ It is well established
    that we may decline to address ‘‘newly raised argument[s]’’ and that ‘‘a claim
    cannot be raised for the first time at oral argument.’’ (Internal quotation
    marks omitted.) Burton v. Dept. of Environmental Protection, 
    337 Conn. 781
    ,
    797 n.12, 
    256 A.3d 655
     (2021). To the extent that the board of representatives
    claims, for the first time on appeal, that the plaintiffs had an obligation to
    appeal from the decision of the planning board referring the protest petition
    to the board of representatives or that the planning board is an indispensable
    party to the present action, we deem these claims abandoned.
    18
    We disagree with the dissent that we have appointed ourselves ‘‘as a
    municipal signature counter . . . .’’ The number of signatures is undisputed
    on appeal, and we resolve no questions of fact in our adjudication of the
    legal issue presented.
