    JONATHAN A. SOBEL v. COMMISSIONER
    OF REVENUE SERVICES
    (SC 20215)
    Robinson, C. J., and Palmer, Mullins, Kahn, Ecker,
    Vertefeuille and DiPentima, Js.
    Syllabus
    The plaintiff taxpayer appealed to the trial court from the decision of the
    defendant, the Commissioner of Revenue Services, denying the plaintiff’s
    protest in connection with the defendant’s denial of state income tax
    credits that the plaintiff sought for nonresident income taxes paid to
    the state of New York on the distributive share of profits that he received
    for managing two limited partnerships. The plaintiff, who resided in
    Connecticut but worked in New York, was a member of a limited liability
    company, L Co., which served as the general manager for the limited
    partnerships. The limited partnerships, which operated as hedge funds
    and primarily traded their own stock index options, paid L Co. a share
    of their profits for L Co.’s services, and L Co., in turn, allocated to the
    plaintiff his distributive share of those profits. In 1997 and 1998, the
    plaintiff reported the income he received from L Co. as capital gains
    on his New York state income tax returns, paid taxes on that income
    to New York, and sought a credit against his Connecticut resident income
    taxes for the taxes he paid to New York during those years pursuant
    to the statute (§ 12-704 [a] [1]) allowing a resident of this state to receive
    a credit against nonresident income tax paid to another state when the
    nonresident income being taxed would otherwise be subject to taxation
    in Connecticut. The defendant disallowed the credit under § 12-704 (a)
    (1), reasoning that the plaintiff’s income must be treated as if it derived
    from trading intangible property for his own account because the limited
    partnerships were trading their own intangible property and the charac-
    ter of the partnerships’ income passed through to the income of their
    general partner, and that Connecticut does not tax nonresidents on
    income from the trading of intangible property for the nonresident’s
    own account pursuant to statute (§ 12-711 [f]). In sustaining the plaintiff’s
    appeal, the trial court first determined that, for purposes of § 12-711 (f),
    the plaintiff was not trading intangible property for his own account
    but was engaging in the trade or business of trading intangible property
    owned by others, namely, the limited partnerships. The trial court also
    determined that, even if the plaintiff was trading intangible property for
    his own account, he nonetheless must be deemed to have been engaged
    in a trade or business, pursuant to Moller v. United States (
    721 F.2d 801
    ), on the basis of the frequency and volume of his trading activity,
    which involved millions of transactions and approximately $250 million.
    The trial court concluded, on the basis of either of those two grounds,
    that the plaintiff would be taxed in Connecticut on such income and,
    therefore, that he was entitled to the credits that he sought for the
    nonresident income taxes he paid to New York. The defendant appealed,
    claiming that the trial court incorrectly concluded that the plaintiff was
    not trading intangible property for his own account but, rather, was
    engaged in the trade or business of trading intangible property owned by
    others. Held that the defendant’s appeal was moot because the defendant
    challenged only one of the trial court’s two independent bases for its
    determination that the plaintiff was entitled to the income tax credits
    he sought, and, accordingly, his appeal was dismissed: the defendant
    conceded that he challenged the trial court’s judgment only on the issue
    of whether the plaintiff was trading intangible property for his own
    account, and, because he did not challenge the alternative ground on
    which the trial court based its decision, namely, that, even if the plaintiff
    was trading intangible property for his own account, the plaintiff none-
    theless was deemed to have been engaged in a trade or business under
    Moller on the basis of the frequency and volume of his trading activity,
    there existed an unchallenged, independent basis for the trial court’s
    decision, and, therefore, there was no relief that this court could afford
    the defendant; moreover, this court rejected the defendant’s claim that
    the trial court’s determination under Moller did not constitute an alterna-
    tive, independent basis for its decision, especially in view of the defen-
    dant’s concession in his posttrial brief to the trial court that the plaintiff
    could be treated as if he were engaged in a trade or business under
    Moller if he was engaged in substantial, daily trading activity.
    Argued April 30—officially released November 19, 2019
    Procedural History
    Appeal from the defendant’s assessment of certain
    personal income tax deficiencies against the plaintiff,
    brought to the Superior Court in the judicial district
    of New Britain, Tax Session, and tried to the court,
    Schuman, J.; judgment sustaining the plaintiff’s appeal,
    from which the defendant appealed. Appeal dismissed.
    Philip Miller, assistant attorney general, with whom
    were Louis P. Bucari, Jr., and, on the brief, George
    Jepsen, former attorney general, for the appellant
    (defendant).
    Jonathan A. Sobel, self-represented, with whom was
    Jonathan M. Shapiro, for the appellee (plaintiff).
    Opinion
    VERTEFEUILLE, J. This appeal arises from a dispute
    as to whether the income of a general partner who lives
    in Connecticut and manages intangible property owned
    by limited partnerships operating in New York consti-
    tutes income derived from trading intangible property
    for the general partner’s own account, in which case it
    would be taxable in this state or, instead, constitutes
    income from a trade or business, in which case it would
    be taxable in New York. The plaintiff, Jonathan A. Sobel,
    who resided in Connecticut and worked in New York,
    was a member of a limited liability company that was
    the managing partner of two limited partnerships that
    operated as hedge funds. The plaintiff reported his
    income derived from the two partnerships on his Con-
    necticut tax returns in 1997 and 1998, and sought a
    credit pursuant to General Statutes § 12-704 (a) (1)1 for
    income taxes that he had paid on the income as a
    nonresident in New York. The defendant, the Commis-
    sioner of Revenue Services (commissioner), disallowed
    the credit after conducting an audit. Specifically, the
    commissioner concluded that the plaintiff was not enti-
    tled to a credit because (1) the plaintiff’s income must
    be treated as if it derived from trading intangible prop-
    erty for his own account2 because the limited partner-
    ships were trading their own intangible property and the
    character of the partnerships’ income passed through
    to the income of their general partner; see General
    Statutes §§ 12-712 (c) (1)3 and 12-715 (b);4 (2) Connecti-
    cut does not tax the income of nonresidents from trad-
    ing intangible property for their own accounts; see Gen-
    eral Statutes § 12-711 (f);5 and (3) residents of this state
    are not entitled to a credit for income taxes paid in
    other states unless Connecticut would tax nonresident
    income of the same character. See General Statutes
    § 12-704 (a) (1). The plaintiff then filed a protest against
    the proposed income tax assessment. The commis-
    sioner denied the protest in relevant part. The plaintiff
    appealed from that denial to the trial court, which,
    after conducting a trial de novo, concluded on two
    independent grounds that the plaintiff was not trading
    intangible property for his own account but was
    engaged in the trade or business of trading intangible
    property owned by the limited partnerships. Accord-
    ingly, the court concluded that the plaintiff was entitled
    to a credit for the income tax that he paid in New York.
    The commissioner then filed this appeal,6 in which he
    challenged only one of the two independent bases for
    the trial court’s decision. After oral argument, this court,
    sua sponte, ordered the parties to submit supplemental
    briefs on the issue of whether the appeal was moot as a
    consequence of the commissioner’s failure to challenge
    both grounds for the trial court’s decision. See, e.g.,
    State v. Lester, 
    324 Conn. 519
    , 526–27, 
    153 A.3d 647
    (2017) (‘‘[w]here an appellant fails to challenge all bases
    for a trial court’s adverse ruling on his claim, even if
    this court were to agree with the appellant on the issues
    that he does raise, we still would not be able to provide
    [him] any relief in light of the binding adverse finding[s]
    [not raised] with respect to those claims,’’ and, there-
    fore, appeal is moot [internal quotation marks omit-
    ted]). The commissioner contended in his supplemental
    brief that the appeal is not moot because there was
    only one basis for the trial court’s ruling that the plaintiff
    was engaged in a trade or business, which he had chal-
    lenged on appeal. The plaintiff contended in his supple-
    mental brief that the appeal is moot. We agree with the
    plaintiff that the appeal is moot because the commis-
    sioner failed to challenge an independent basis for the
    trial court’s ruling and that the appeal must therefore
    be dismissed.
    The record reveals the following relevant facts, which
    were found by the trial court or are undisputed, and
    procedural history. The plaintiff and his brother, Peter
    Sobel, were the sole members of a limited partnership,
    Livingston Asset Management, LLC (LAM, LLC), which
    acted as the general partner of two limited partnerships,
    Livingston Asset Management, LP (LAM, LP), and Liv-
    ingston International Fund, LP (LIF, LP). LAM, LP, and
    LIF, LP, were hedge funds, and the function of LAM,
    LLC, was to manage their assets. The limited partner-
    ships made profits primarily from the trading of United
    States treasury bills and stock index options that were
    owned by the partnerships. LAM, LLC, received approx-
    imately 30 percent of the partnerships’ profits, one half
    of which, in turn, was allocated to the plaintiff.
    In 1997 and 1998, the plaintiff, who resided in Con-
    necticut and worked in New York,7 reported the income
    that he received from LAM, LLC, as capital gains on his
    federal and New York income tax returns, and he paid
    taxes on the income in those jurisdictions. The plaintiff
    also reported the income on his Connecticut tax return,
    and he sought a credit pursuant to § 12-704 (a) (1) for
    the income taxes that he had paid as a nonresident in
    New York. The commissioner concluded that, because
    the limited partnerships’ profits were derived from trad-
    ing intangible property for their own accounts, that
    income characterization must be passed through to the
    plaintiff. See General Statutes § 12-712 (c) (1) (charac-
    ter of partner’s income is determined in accordance
    with § 12-715); General Statutes § 12-715 (b) (‘‘[e]ach
    item of partnership . . . income . . . shall have the
    same character for a partner . . . as for federal income
    tax purposes’’); see also 26 U.S.C. § 702 (b) (2012) (part-
    ner’s income from distributive share has same character
    as if income were realized directly from source from
    which partnership realized income). Because Connecti-
    cut does not tax the income of nonresidents derived
    from trading intangible property for their own accounts;
    see General Statutes § 12-711 (f); the commissioner con-
    cluded that the plaintiff was not entitled to a credit for
    the income tax that he paid in New York. See General
    Statutes § 12-704 (a) (1) (Connecticut resident may be
    allowed credit for income tax paid in another state only
    if same form of nonresident income would be taxable
    in Connecticut). The plaintiff then filed a protest against
    the proposed assessment, which the commissioner
    denied in relevant part.
    The plaintiff appealed from the commissioner’s deci-
    sion to the trial court pursuant to General Statutes § 12-
    730, and the trial court conducted a trial de novo. Cf.
    Leonard v. Commissioner of Revenue Services, 
    264 Conn. 286
    , 294, 
    823 A.2d 1184
    (2003) (‘‘[a] sales and use
    tax appeal taken pursuant to [General Statutes] § 12-
    422 is a trial de novo’’ [internal quotation marks omit-
    ted]). In his posttrial brief, the plaintiff contended that
    he was entitled to a credit for the income taxes that
    he paid in New York because his income was derived
    from the trade or business of trading intangible property
    owned by others, namely, the limited partnerships. The
    commissioner contended in his posttrial brief that, to
    the contrary, because the income of the limited partner-
    ships was derived from the trading of intangible prop-
    erty for their own accounts, that character must be
    passed through to the income of their general partner,
    LAM, LLC, and, in turn, to the plaintiff’s income.
    The commissioner conceded, however, in his post-
    trial brief that, even if the trial court agreed with him
    that the plaintiff ordinarily would be deemed to have
    been trading intangible property for his own account,
    the plaintiff still could be treated as if he were engaged
    in a trade or business for state income tax purposes if
    he was engaged in ‘‘substantial, daily trading activity.’’
    The commissioner cited Moller v. United States, 
    721 F.2d 810
    (Fed. Cir. 1983), cert. denied, 
    467 U.S. 1251
    ,
    
    104 S. Ct. 3534
    , 
    82 L. Ed. 2d 839
    (1984), among other
    cases, in support of this proposition. See 
    id., 813 (‘‘[i]n
    determining whether a taxpayer who manages his own
    investments is a trader, and thus engaged in a trade
    or business, relevant considerations are the taxpayer’s
    investment intent, the nature of the income to be
    derived from the activity, and the frequency, extent,
    and regularity of the taxpayer’s securities transac-
    tions’’); see also Stoller v. Commissioner of Internal
    Revenue, T. C. Memo 1990-659, 
    60 T.C.M. 1554
    ,
    1562, T.C.M. (P-H) P90,659 (T.C. 1990) (‘‘[w]hen a tax-
    payer, in this case a partnership, is trading solely for
    its own account, the volume of trading must be very
    regular and substantial in order to rise to the level of
    a trade or business’’), rev’d in part on other grounds,
    
    994 F.2d 855
    (D.C. Cir. 1993), amended, 
    3 F.3d 1576
    (D.C. Cir. 1994).8 The commissioner argued that the
    plaintiff’s income could not be treated as if it derived
    from conducting a trade or business under the Moller
    line of cases because he had ‘‘not presented any evi-
    dence of any trading activity, other [than] his own vague
    testimony in which he claims he made a lot of trades.’’
    The trial court agreed with the plaintiff that he was
    not trading for his own account but was in the trade
    or business of trading intangible property owned by
    others, namely, the limited partnerships. The trial court
    then observed that, ‘‘[i]n arguing that the plaintiff did
    not engage in a trade or business, the commissioner
    relies on a line of federal cases that distinguish[es]
    between persons trading securities who are investors
    and persons who engage in that activity as a trade or
    business, sometimes referred to as traders or day trad-
    ers.’’9 (Internal quotation marks omitted.) The court
    concluded that these cases were ‘‘inapplicable because
    they all involve persons who were investing their own
    money or their family’s money,’’ and the court already
    had concluded that the plaintiff was in the trade or
    business of managing property owned by others. The
    court also concluded, however, that, ‘‘even under the
    standards urged by the commissioner’’—that is, even
    if the commissioner were correct that the plaintiff had
    to satisfy the Moller standard to be treated as if he were
    engaged in a trade or business because a general partner
    who trades intangible property belonging to the limited
    partnership ordinarily is deemed to be trading for his
    own account for state income tax purposes—the plain-
    tiff still must be treated as if he were engaged in a trade
    or business because he ‘‘commuted every workday to
    an office where he worked long hours, met with clients
    and investors, engaged in millions of trades, and man-
    aged approximately $250 million of their money. The
    daily frequency and enormous volume of the plaintiff’s
    trading activity clearly satisfy the day trading stan-
    dards.’’ (Emphasis added.) The trial court thus con-
    cluded both that (1) the plaintiff was engaged in the
    business of trading intangible property belonging to
    others, and (2) even if he ordinarily would be deemed
    to have been trading intangible property for his own
    account because the character of the partnerships’
    income producing activity passed through to him, he
    still must be treated as if he were conducting a trade
    or business under the Moller line of cases. For these
    reasons, the trial court concluded that the plaintiff was
    entitled to a credit for the income taxes that he paid
    in New York.10
    This appeal followed. The commissioner contended
    in his main appellate brief that the trial court incorrectly
    determined that the plaintiff was not trading intangible
    property for his own account but was engaged in the
    trade or business of trading intangible property owned
    by others, namely, the limited partnerships.11 The com-
    missioner did not, however, challenge the trial court’s
    ruling that, even if the plaintiff ordinarily would be
    deemed to be trading intangible property for his own
    account, he still could be deemed to have been engaged
    in a trade or business under the Moller standard.
    Accordingly, after oral argument, this court, sua sponte,
    ordered the parties to submit supplemental briefs on
    the issues of whether the commissioner had challenged
    that independent basis for the trial court’s ruling and,
    if not, whether the appeal therefore was moot under
    State v. 
    Lester, supra
    , 
    324 Conn. 526
    –27.
    The commissioner concedes in his supplemental brief
    that he did not challenge the trial court’s conclusion
    that the plaintiff was engaged in a trade or business
    under Moller in his initial appellate brief. The commis-
    sioner contends, however, that the appeal is not moot
    because the trial court’s conclusion does not provide
    an independent basis for its ruling that the plaintiff was
    engaged in a trade or business so as to make his income
    taxable in New York. Specifically, the commissioner
    contends that the trial court ‘‘could not and did not
    conclude that the plaintiff could receive income from
    trading for his own account and have that same income
    be considered income from property employed in a
    trade or business.’’ (Emphasis in original.) As we
    explained, however, the commissioner conceded in his
    posttrial brief that, even if the trial court concluded that
    the plaintiff’s conduct in trading the intangible property
    belonging to the limited partnerships ordinarily would
    be deemed to be trading for his own account, that same
    conduct could be treated as a trade or business if the
    court found that the plaintiff had satisfied the Moller
    standard, in which case the plaintiff would be entitled
    to a credit for the income taxes that he paid in New
    York.12 Accordingly, it is entirely unclear to us why the
    commissioner now claims that the trial court ‘‘could
    not and did not’’ conclude that the plaintiff’s trading
    of intangible property should be treated as a trade or
    business, even if the conduct ordinarily would be
    deemed to be trading for his own account.
    To the extent that the commissioner claims that the
    trial court had no need to address the Moller issue
    because it already had concluded that the plaintiff was
    engaged in a trade or business of trading intangible
    property belonging to others, it is clear that the court’s
    ruling pursuant to Moller was a ruling in the alternative,
    which is entirely proper.13 To the extent that the com-
    missioner contends that the Moller line of cases is rele-
    vant only to the issue of whether the stock index options
    were ‘‘property employed in a business, trade or profes-
    sion’’ within the meaning of § 12-704(a)-4 (a) (3) of the
    Regulations of Connecticut State Agencies;14 (emphasis
    added); which the court would not have needed to
    address if it had concluded that the plaintiff was trading
    intangible property for his own account, that claim is
    both illogical and inconsistent with the commissioner’s
    position in his posttrial brief to the trial court. Moller,
    by its plain terms, provides a standard for determining
    whether an individual who is trading intangible property
    for his own account nevertheless may be treated as if
    he were engaged in a trade or business. Indeed,
    although the trial court discussed Moller in the portion
    of its memorandum of decision addressing the opera-
    tion of § 12-704(a)-4 (a) (3), the court expressly stated
    that the Moller line of cases went to the issue of whether
    the plaintiff was engaged in a trade or business. It is
    also clear that the trial court found that the ‘‘trade
    or business’’ in which the plaintiff was engaged under
    Moller was trading the intangible property owned by
    the limited partnerships. Indeed, the commissioner
    does not suggest that the court found that the plaintiff
    was engaged in some other trade or business.
    The commissioner also contends that, even if the
    plaintiff was engaged in a trade or business when he
    traded the intangible property owned by the limited
    partnerships for purposes of Moller, he still would not
    be entitled to a credit because the stock index options
    that he traded were not ‘‘property employed in a busi-
    ness, trade or profession . . . .’’ Regs., Conn. State
    Agencies § 12-704(a)-4 (a) (3). In his posttrial brief to
    the trial court, however, the commissioner contended
    only that the stock index options were not property
    employed in a trade or business because the plaintiff
    was not engaged in a trade or business but was trading
    intangible property for his own account. On appeal,
    the commissioner for the first time cites Michaelson v.
    Tax Commission, 
    67 N.Y.2d 579
    , 
    496 N.E.2d 674
    , 
    505 N.Y.S.2d 585
    (1986), to support his claim that, even if
    the plaintiff was engaged in a trade or business, the
    plaintiff’s income did not derive from property
    employed in the trade or business. In Michaelson, the
    New York Court of Appeals concluded that income
    derived from an increase in the market value of stock
    owned by the nonresident taxpayer between the time
    he exercised his option to purchase the stock and the
    time the stock was sold was not taxable ‘‘income . . .
    from property employed in a business, trade, profes-
    sion, or occupation’’; (internal quotation marks omit-
    ted) 
    id., 583; but
    was nontaxable investment income.
    
    Id., 585. There
    was no claim in Michaelson, however,
    that the taxpayer should be deemed to be engaged in
    the trade or business of trading stock options, notwith-
    standing the fact that he owned the stock options at
    issue. Accordingly, we conclude that Michaelson has
    no bearing on the present case.
    The commissioner also relies on § 12-711(b)-5 (b) of
    the Regulations of Connecticut State Agencies, which
    provides in relevant part: ‘‘Intangible personal property
    is employed in a business, trade, profession or occupa-
    tion carried on in this state if such property’s possession
    and control have been localized in connection with a
    business, trade, profession or occupation in Connecti-
    cut, so that the property’s substantial use and value
    attach to and become an asset of such business, trade,
    profession or occupation. . . .’’ Section 12-711(b)-5 (b)
    then provides the following two examples of intangible
    property owned by a nonresident being employed by a
    business in this state: (1) ‘‘a nonresident pledges stocks,
    bonds or other intangible personal property in Connect-
    icut as security for the payment of indebtedness
    incurred in connection with a business being carried
    on in Connecticut by the nonresident’’; and (2) ‘‘a non-
    resident maintains a branch office in Connecticut and
    an interest-bearing checking account on which the
    agent in charge of the branch office may draw checks
    for the payment of expenses in connection with the
    activities in this state.’’ The commissioner points out
    that the circumstances of the present case do not con-
    form to either example and, therefore, contends that
    Connecticut would not tax a nonresident’s income that
    had the same character as the plaintiff’s.
    The commissioner fails to recognize, however, that
    it follows from the trial court’s conclusion that the
    plaintiff must be treated as if he were engaged in a trade
    or business—either because he was trading intangible
    property owned by others15 or because he must be
    deemed to have been trading intangible property for
    his own account but satisfied the Moller standard—that
    he also must be treated as if he did not personally own
    the intangible property that he traded. This is because,
    for state income tax purposes, the concepts of operating
    a trade or business and trading intangible property for
    one’s own account, which is defined as trading one’s
    own property; see footnote 2 of this opinion; are mutu-
    ally exclusive. Because the plaintiff was deemed not to
    own the intangible property, the property could not
    be tied to the plaintiff’s domicile in Connecticut; see
    footnote 5 of this opinion; and, therefore, income
    derived from the property could not be taxed in this
    state. Put another way, it was implicit in the trial court’s
    ruling that the plaintiff’s trading activities constituted
    a trade or business, and the income from those activities
    should be taxed in the locale where they took place.
    See Regs., Conn. State Agencies § 12-711(b)-4 (a) (1)
    (income attributable to business, trade, profession or
    occupation carried on in Connecticut is taxable in Con-
    necticut).
    To the extent that the commissioner contends that
    the trial court ‘‘could not and did not’’ conclude that
    the plaintiff’s trading activities on behalf of the limited
    partnerships constituted a trade or business under
    Moller because, under § 12-711(f)-1 (a) of the Regula-
    tions of Connecticut State Agencies,16 income from trad-
    ing intangible property for one’s own account can never
    be treated as income from a trade or business, that
    position is also inconsistent with the position that the
    commissioner took in his posttrial brief. Specifically,
    the commissioner conceded that, if the plaintiff satis-
    fied the Moller standard, he could be deemed not to be
    trading for his own account, in which case § 12-711(f)-
    1 (a) simply would not apply. Although § 12-711(f)-1 (a)
    expressly provides that a nonresident’s income from
    trading for his own account shall not be included in
    his Connecticut adjusted gross income derived from
    engaging in a trade or business, it does not expressly
    prohibit the commissioner from ever treating income
    from trading intangible property for one’s own account
    as if it were income derived from a trade or business. In
    any event, the argument that this court should conclude
    that the trial court’s ruling that the plaintiff was engaged
    in a trade or business under the Moller standard was
    not an independent basis for its decision because any
    such ruling would have been self-evidently incorrect
    amounts to a back door attempt to challenge the ruling,
    which the commissioner contends he had no reason to
    do because the ruling was not an independent ground
    for the trial court’s decision in the first instance. Thus,
    this argument is circular and constitutes an attempt to
    end-run the principle that the failure to challenge an
    independent basis for the trial court’s ruling on appeal
    renders the appeal moot.17 See State v. 
    Lester, supra
    ,
    
    324 Conn. 526
    –27.
    The commissioner finally contends that the notion
    that the trial court’s ruling pursuant to Moller provides
    an independent basis for its decision is belied by the
    fact that the plaintiff made no claim in his initial appel-
    lee’s brief that he could be deemed to be engaged in a
    trade or business pursuant to the Moller line of cases,
    even if this court concluded that a general partner who
    trades intangible property owned by the limited partner-
    ships is ordinarily deemed to be trading property on
    his own account. We disagree. For the reasons that we
    already explained, it is clear to us that the trial court’s
    ruling pursuant to Moller provided an independent basis
    for its conclusion that the plaintiff was engaged in a
    trade or business. Indeed, although the commissioner
    expounds at length as to the reasons that he believes
    the trial court’s ruling pursuant to Moller did not consti-
    tute an independent basis for its decision that the plain-
    tiff was not trading intangible property for his own
    account but, instead, was engaged in a trade or busi-
    ness, he provides no convincing reasons why the trial
    court would have had any reason to address Moller if
    it did not provide an independent basis for its decision.
    Having reached this conclusion, we decline to speculate
    as to why the plaintiff did not alert this court to this
    alternative ground for the trial court’s ruling in his main
    brief. The commissioner has provided no authority for
    the proposition that, if an appellee fails to claim on
    appeal that the appellant has not challenged an indepen-
    dent basis for the trial court’s decision, the reviewing
    court may presume either that the appellee believes
    that there was no valid independent basis or, if there
    was one, that the appellee has waived any reliance on
    it. Indeed, we also note that, because mootness impli-
    cates the court’s subject matter jurisdiction, it cannot
    be waived. See, e.g., Wilcox v. Webster Ins., Inc., 
    294 Conn. 206
    , 222, 
    982 A.2d 1053
    (2009).
    We conclude that, contrary to the commissioner’s
    contention, the trial court’s ruling pursuant to Moller
    was an independent basis for its conclusion that the
    plaintiff was engaged in a trade or business when he
    traded intangible property owned by the limited part-
    nerships, and, therefore, the plaintiff was entitled to a
    credit for the income tax that he paid in New York.
    The commissioner makes no claim that, if this court
    concludes that the trial court’s ruling pursuant to Moller
    provides an independent basis for the trial court’s deci-
    sion, the appeal would not be moot as the result of the
    commissioner’s failure to challenge the ruling on appeal
    pursuant to State v. 
    Lester, supra
    , 
    324 Conn. 526
    –27.
    We conclude, therefore, that the appeal must be dis-
    missed as moot.
    The appeal is dismissed.
    In this opinion the other justices concurred.

    The commissioner appealed to the Appellate Court, and we subsequently
    granted his motion to transfer the appeal to this court pursuant to General
    Statutes § 51-199 (c) and Practice Book § 65-2.
    7
    The plaintiff claims that he became a resident of New York in July, 1998.
    See footnote 11 of this opinion. Because this claim has no bearing on the
    issue before us, we assume for purposes of this opinion that he was a
    resident of Connecticut during the relevant time period.
    8
    As far as we have been able to determine, the plaintiff did not cite to
    the Moller line of cases in the proceedings before the trial court.
    9
    As we have explained, the commissioner did not rely on the Moller line
    of cases to support his position that the plaintiff was trading intangible
    property for his own account. Rather, because the application of this line
    of cases could only be unfavorable to the commissioner in that it provided
    an alternative route to the conclusion that the plaintiff was engaged in a
    trade or business, it is reasonable to presume that the commissioner cited
    Moller in furtherance of his duty to bring adverse authority to the attention
    of the trial court. See Rules of Professional Conduct 3.3 (a) (2) (‘‘[a] lawyer
    shall not knowingly . . . [f]ail to disclose to the tribunal legal authority in
    the controlling jurisdiction known to the lawyer to be directly adverse to
    the position of the client and not disclosed by opposing counsel’’).
    10
    Thus, the trial court effectively concluded that, even if the commissioner
    were correct that the partnerships’ income ordinarily would be considered
    to derive from trading intangible property on their own accounts, and even
    if the commissioner were correct that that character would pass through
    to the plaintiff pursuant to § 12-715 (b) so that the plaintiff ordinarily would
    be deemed to be trading on his own account, the volume of trading was
    sufficiently regular and substantial to compel the conclusion that both the
    partnerships and the plaintiff must be deemed to be engaged in a trade or
    business under Moller.
    11
    The commissioner also challenged the trial court’s ruling that, even if
    the plaintiff was not entitled to a credit for the income taxes that he paid
    in New York because he was trading intangible property for his own account,
    he was entitled to a reduction in his income tax assessment for 1998 because
    he became a resident of New York in July of that year. The trial court
    apparently believed that it was not required to reach this issue in light of
    its conclusion that the plaintiff was entitled to a credit, and it addressed
    the issue only in the event that the reviewing court found it necessary to
    reach the issue on appeal. In his brief, the plaintiff also characterizes this
    claim in his main appellate brief as an ‘‘alternative argument.’’ Accordingly,
    because we conclude that the commissioner’s appeal from the trial court’s
    ruling that the plaintiff was entitled to a credit must be dismissed as moot,
    we need not address the domicile issue.
    12
    The commissioner stated in his posttrial brief that the fact that the
    plaintiff must be deemed under state income tax law to be trading intangible
    property for his own account was ‘‘not the end of the analysis, as there are
    certain situations in which a general partner may be deemed to be engaged
    in a trade or business separate and apart from that of the partnership.’’ The
    commissioner then quoted the standard set forth in § 12-711(c)-2 of the
    Regulations of Connecticut State Agencies for determining whether an activ-
    ity constitutes a trade or business, and noted that, under § 12-711(f)-1 (a)
    of the regulations, a nonresident who sells stock option contracts for his
    own account is deemed not to be carrying on a business. See Regs., Conn.
    State Agencies § 12-711(f)-1 (a) (‘‘[w]here a nonresident individual who is
    not a dealer buys and sells property, or buys, sells or writes stock option
    contracts, or both, for his or her own account, such nonresident individual
    is not deemed to be carrying on a business, trade, profession or occupation
    within Connecticut’’). The commissioner stated that, ‘‘[a]ccordingly, other
    than trading for one’s own account, a taxpayer will be entitled to a credit
    for tax paid to another jurisdiction if the taxpayer maintains an office in
    said jurisdiction and systematically and regularly conducts its affairs in said
    jurisdiction or conducts its business with a fair measure of permanency and
    continuity.’’ (Emphasis added.) The commissioner then observed that, under
    the Moller line of cases, a taxpayer who trades intangible property for his
    own account and who would, therefore, ordinarily be deemed not to be
    engaged in a trade or business, may nevertheless be deemed to be engaged
    in a trade or business if the taxpayer engages in ‘‘substantial, daily trad-
    ing activity.’’
    In his supplemental brief to this court, the commissioner appears to
    contend that a conclusion that the plaintiff must be deemed to have been
    trading intangible property for his own account is the end of the analysis,
    because there are no circumstances under which that activity can be deemed
    to be a trade or business under Connecticut law. Although this position is
    consistent with the commissioner’s statement in his posttrial brief that the
    activity of trading for one’s own account is excepted from the regulatory
    standard for determining whether an activity is a trade or business, there
    would have been no reason for the commissioner to discuss the Moller line
    of cases in this context unless he believed that the cases provided an
    exception to that exception. Moreover, that position would be consistent
    with the commissioner’s statement in his posttrial brief that a determination
    that the plaintiff was trading intangible property for his own account was
    not the end of the analysis. Accordingly, although the commissioner’s post-
    trial brief is not a model of clarity, the most reasonable reading is that the
    commissioner conceded that, even if the plaintiff ordinarily would be deemed
    to be trading for his own account when he traded intangible property belong-
    ing to the partnerships, if the plaintiff could satisfy the Moller standard, he
    could be deemed to be engaged in a trade or business and, therefore, would
    be entitled to a credit.
    13
    In other words, contrary to the commissioner’s suggestion, the trial
    court did not conclude that the plaintiff was both trading for his own account
    and engaged in a trade or business. Rather, the court concluded that, even
    if the commissioner were correct that the plaintiff would ordinarily be
    deemed to be trading intangible property for his own account, the income
    from which would be taxable in Connecticut, the plaintiff should be deemed
    not to be trading on his own account because his trading activities met the
    Moller standard for engaging in a trade or business, the income from which
    was taxable in New York.
    14
    Section 12-704(a)-4 (a) (3) of the Regulations of Connecticut State Agen-
    cies provides in relevant part: ‘‘[T]he credit is not allowed for tax imposed
    by another jurisdiction upon income from intangibles, except where such
    income is from property employed in a business, trade or profession carried
    on in the other jurisdiction. . . .’’
    15
    To the extent that the commissioner suggests that the trial court’s
    conclusion that the plaintiff’s income did not derive from trading intangible
    property for his own account because he was trading intangible property
    owned by the limited partnerships did not imply that the plaintiff’s income
    derived from a trade or business, he has not explained how, if the plaintiff’s
    income derived neither from trading intangible property for his own account
    nor from a trade or business, the source of the income should be charac-
    terized.
    16
    Section 12-711(f)-1 (a) of the Regulations of Connecticut State Agencies
    provides in relevant part: ‘‘If the nonresident individual is otherwise carrying
    on a business, trade, profession or occupation within Connecticut, his or
    her income from buying and selling property, or buying, selling or writing
    stock option contracts, or both, for his or her own account, shall not be
    included in Connecticut adjusted gross income derived from or connected
    with sources within this state.’’
    17
    We note that, because the commissioner conceded in his posttrial brief
    that the trial court could conclude that the plaintiff’s trading of intangible
    property owned by the limited partnerships constituted a trade or business
    if the plaintiff presented sufficient evidence to satisfy the Moller standard,
    it would appear that any error by the trial court in applying the Moller
    standard was induced by the commissioner, and, therefore, any challenge
    to the ruling on grounds other than evidentiary insufficiency likely would
    have been unreviewable, even if the commissioner had raised the challenge
    in his main appellate brief. See State v. Cruz, 
    269 Conn. 97
    , 105, 
    848 A.2d 445
    (2004).
    We emphasize that we express no opinion as to whether the trial court
    correctly applied the Moller standard to determine the geographical source
    of the plaintiff’s income for state income tax purposes. We note that Moller
    involved a federal income tax statute that allowed a deduction for business
    expenses attributable to the maintenance of an office in the taxpayer’s
    personal residence when the office is the ‘‘principal place of business for
    any trade or business of the taxpayer.’’ (Internal quotation marks omitted.)
    Moller v. United 
    States, supra
    , 
    721 F.2d 812
    . It is far from self-evident that
    a standard designed to determine whether a taxpayer who is trading for his
    own account is entitled to certain federal income tax deductions that are
    available only to a trade or a business may also be used to determine the
    source of a taxpayer’s income for state income tax purposes. Regardless
    of whether the trial court’s ruling pursuant to Moller was correct, however,
    we conclude that the ruling was an independent basis for the trial court’s
    decision, and the commissioner did not, and likely could not, challenge the
    ruling on appeal.
