    ESTATE OF HELEN B. BROOKS

    Opinion
    EVELEIGH J. The plaintiffs, the coexecutors of the
    estate of Helen B. Brooks,1 appeal from the trial court’s
    rendering of summary judgment in favor of the defen-
    dant, the Commissioner of Revenue Services.2 The trial
    court upheld the decision of the defendant to deny the
    plaintiffs’ request for a refund of estate taxes paid by
    the estate of the decedent, Helen B. Brooks (decedent).
    On appeal, the plaintiffs claim that the trial court incor-
    rectly concluded that the defendant had statutory
    authority to include in the decedent’s gross estate the
    value of certain qualified terminable interest property
    (QTIP) in which the decedent enjoyed a life interest
    and levy an estate tax upon such property. The plaintiffs
    also assert that the defendant’s construction of the stat-
    ute resulted in a violation of the plaintiffs’ due process
    rights. We disagree with the plaintiffs and, accordingly,
    affirm the judgment of the trial court.
    The following facts and procedural history are rele-
    vant to this appeal. The material facts in this case are
    not in dispute. The decedent died on September 22,
    2009, domiciled in Connecticut. She was predeceased
    by her husband, Everett Brooks (Everett), who died
    January 31, 2000. Everett was a resident of Florida at
    the time of his death. At that time, Florida and Connecti-
    cut each had an estate tax based on the amount of the
    federal credit allowed for state death taxes. See 26
    U.S.C. § 2011 (2000); General Statutes (Rev. to 1999)
    § 12-391; Fla. Stat. § 198.02 (2000). Everett’s will was
    probated in Florida. Pursuant to Everett’s will, two
    trusts were created to hold certain assets of the estate.3
    The decedent, acting as executor of Everett’s estate,
    elected to qualify both trusts as QTIP marital deduction
    trusts. See 26 U.S.C. § 2056 (b) (7) (2000). Pursuant to
    Everett’s will, the decedent enjoyed a beneficial life
    interest in the assets of the trusts. Everett’s will also
    granted the decedent a testamentary limited power of
    appointment to direct the remainder of the trusts among
    Everett’s children. In the absence of such an appoint-
    ment by the decedent, the principal of the trusts was
    to be distributed according to Everett’s will. The trusts
    consisted of intangible personal property—namely,
    cash and publicly traded stocks and bonds. The dece-
    dent and Attorney Herbert J. Hummers were appointed
    trustees of the trusts. Hummers was given the power
    to invade the principal of the trusts for the benefit of
    the decedent.4 The decedent did not have the power to
    invade the principal of the trust. In or about 2002, the
    decedent moved to Connecticut and lived in the state
    continuously until her death.
    After the decedent’s death, the plaintiffs timely filed
    a request for extension and made an estimated tax
    payment of $1,435,000. On November 4, 2010, the plain-
    tiffs timely filed a Connecticut estate tax return for the
    decedent’s estate that intentionally omitted the value
    of the trusts and claimed a refund in the amount of
    $988,827. The plaintiffs included a statement on the
    return asserting that the value of those assets was not
    properly includable in the Connecticut gross estate of
    the decedent. The defendant’s audit division disallowed
    the plaintiffs’ request for a refund. The plaintiffs subse-
    quently filed a timely appeal to the defendant’s appellate
    division, which affirmed. The plaintiffs then filed a
    timely appeal from that decision to the trial court pursu-
    ant to General Statutes §§ 12-395 (a) (1) and 12-554.

    appeal dismissed, 
    312 Conn. 282
    , 
    91 A.3d 902
    (2014).
    On cross motions for summary judgment, the trial court
    concluded that the assets of the trusts were properly
    included in the decedent’s gross estate and, therefore,
    were subject to the estate tax. In addition, the trial
    court concluded that the imposition of the tax upon
    the estate did not violate the due process clause of the
    fourteenth amendment to the United States constitu-
    tion. Accordingly, the trial court denied the plaintiffs’
    motion for summary judgment and granted the defen-
    dant’s motion. The trial court then rendered judgment
    thereon in favor of the defendant. This appeal followed.
    Additional facts and procedural history will be set forth
    as necessary.

    I
    We begin by discussing the background of the federal
    tax concepts implicated in the present case. In 1981,
    Congress enacted ‘‘the most dramatic and expansive
    liberalization of the [m]arital [d]eduction in history.’’
    Estate of Clayton v. Commissioner of Internal Reve-
    nue, 
    976 F.2d 1486
    , 1492 (5th Cir. 1992). Such a feat
    was achieved in two ways. First, Congress provided for
    the unlimited marital deduction. Economic Recovery
    Tax Act of 1981, Pub. L. 97-34, § 403 (a), 95 Stat. 301; see
    also 26 U.S.C. § 2056 (a).5 Federal law did not, however,
    previously allow for the deduction of terminable inter-
    ests. Estate of Clayton v. Commissioner of Internal
    
    Revenue, supra
    , 1492. Mindful of rising divorce and
    remarriage rates, Congress created an exception to the
    general rule against allowing a deduction for the inter-
    spousal transfer of terminable interests so that a dece-
    dent may exert more control over the ultimate
    disposition of certain assets while still financially pro-
    viding for the surviving spouse with such assets unbur-
    dened by front end taxation. See 
    id., 1492–93 and
    n.26.
    Thus, the concept of QTIP was born. 
    Id., 1493. Federal
    tax law currently operates by granting the
    marital deduction to the first to die spouse in the
    amount of the value of certain property, subject to cer-
    tain qualifications, so long as the first to die spouse
    gives a beneficial life interest in such property to the
    surviving spouse. 26 U.S.C. § 2056 (b) (7).6 In order to
    ensure that the property does not pass to the remainder
    beneficiaries untaxed, the federal tax code imposes a
    tax upon the happening of two events. During the life
    of the surviving spouse, any disposition of a qualifying
    life interest in property is treated as a transfer of the
    remainder interest in such property for purposes of the
    gift tax. See 26 U.S.C. § 2519 (a).7 To the extent that
    the surviving spouse did not make any inter vivos dispo-
    sition of any qualifying life interest in property, the
    entire value of the property in which the surviving
    spouse enjoyed a qualifying life interest is included in
    his or her gross estate and is treated as property passing
    therefrom. See 26 U.S.C. § 2044.8 In short, a fictional
    transfer occurs from the first to die spouse to the surviv-
    ing spouse, and a second fictional transfer occurs upon
    the death of the surviving spouse to the remainder bene-
    ficiaries. We note that, in the present case, it is undis-
    puted that the assets contained within the trusts
    established pursuant to Everett’s will were properly
    included in the decedent’s federal gross estate.
    II
    First, we address the plaintiffs’ claim that, pursuant to
    General Statutes § 12-391 (c) (3),9 the assets contained
    within the trusts are not includable in the decedent’s
    gross estate. Specifically, the plaintiffs claim that the
    relevant federal estate tax provisions have been incor-
    porated into the state estate tax provisions and, there-
    fore, the assets contained within the trusts form part
    of the decedent’s state gross estate only if the state
    allowed a deduction with respect to the transfer of such
    property to the decedent following Everett’s death. The
    defendant claims that such an interpretation of § 12-
    391 (c) (3) is inconsistent with the plain meaning of
    the provision—namely, that the gross estate for state
    estate tax purposes is the same as the gross estate for
    federal estate tax purposes. We agree with the
    defendant.
    The plaintiffs’ claim implicates a matter of statutory
    construction. Our standard of review for statutory con-
    struction claims is well established. ‘‘When construing
    a statute, [the court’s] fundamental objective is to ascer-
    tain and give effect to the apparent intent of the legisla-
    ture. . . . In other words, [the court seeks] to
    determine, in a reasoned manner, the meaning of the
    statutory language as applied to the facts of [the] case,
    including the question of whether the language actually
    does apply. . . . In seeking to determine that meaning
    . . . [General Statutes] § 1-2z directs [the court] first
    to consider the text of the statute itself and its relation-
    ship to other statutes. If, after examining such text and
    considering such relationship, the meaning of such text
    is plain and unambiguous and does not yield absurd or
    unworkable results, extratextual evidence of the mean-
    ing of the statute shall not be considered. . . . The test
    to determine ambiguity is whether the statute, when
    read in context, is susceptible to more than one reason-
    able interpretation.’’ (Internal quotation marks omit-
    ted.) Allen v. Commissioner of Revenue Services, 
    324 Conn. 292
    , 307–308, 
    152 A.3d 488
    (2016). ‘‘[A]long with
    these principles, we are also guided by the applicable
    rules of statutory construction specifically associated
    with the interpretation of tax statutes. . . . [W]hen the
    issue is the imposition of a tax, rather than a claimed
    right to an exemption or a deduction, the governing
    authorities must be strictly construed . . . in favor of
    the taxpayer. . . . Nevertheless, [i]t is also true . . .
    that such strict construction neither requires nor per-
    mits the contravention of the true intent and purpose of
    the statute as expressed in the language used.’’ (Internal
    quotation marks omitted.) Groton v. Commissioner of
    Revenue Services, 
    317 Conn. 319
    , 328–29, 
    118 A.3d 37
    (2015).
    We acknowledge that ‘‘when our tax statutes refer
    to the federal tax code, federal tax concepts are incor-
    porated into state law.’’ (Internal quotation marks omit-
    ted.) Allen v. Commissioner of Revenue 
    Services, supra
    ,
    
    324 Conn. 305
    n.15. Nevertheless, we have explained
    that ‘‘this rule does not require the wholesale incorpora-
    tion of the entire body of federal tax principles into our
    state income tax scheme . . . .’’ (Internal quotation
    marks omitted.) 
    Id. Instead, ‘‘where
    a reference to the
    federal tax code expressly is made in the language of
    a statute, and where incorporation of federal tax prin-
    ciples makes sense in light of the statutory language
    at issue, our prior cases uniformly have held that incor-
    poration should take place.’’ (Emphasis added; internal
    quotation marks omitted.) 
    Id. In the
    present case, the statutory language provides
    that the term gross estate ‘‘means the gross estate, for
    federal estate tax purposes.’’ General Statutes § 12-391
    (c) (3). The plain language of the statute requires noth-
    ing more than the gross estate as reported on the federal
    estate tax return. The construction urged by the plain-
    tiffs would result in a value of the gross estate for state
    estate tax purposes that would differ from the value of
    the gross estate for federal estate tax purposes. Specifi-
    cally, looking at whether Connecticut deducted the
    value of a QTIP trust from the estate of the first to die
    spouse in order to ascertain whether such assets are
    to be included in the state gross estate of the surviving
    spouse would not be ‘‘for federal estate tax purposes.’’
    General Statutes § 12-391 (c) (3). Thus, according to
    § 12-391 (c) (3), if assets are included in a decedent’s
    federal gross estate, they are included in his or her state
    gross estate as well.
    In addition, this construction is buttressed by § 12-
    391 (f) (2), which provides: ‘‘An election under said [26
    U.S.C. § 2056 (b) (7)] may be made for state estate tax
    purposes regardless of whether any such election is
    made for federal estate tax purposes. The value of the
    gross estate shall include the value of any property in
    which the decedent had a qualifying income interest
    for life for which an election was made under this sub-
    section.’’ (Emphasis added.) Thus, the legislature has
    created a separate state QTIP election and inclusion
    provision. Construing § 12-391 (c) (3) to require the
    state to have first granted a deduction for the value of
    a QTIP trust from the gross estate of the first to die
    spouse in order to properly include the value of such
    in assets in the gross estate of the surviving spouse
    would, in essence, create a state QTIP election by incor-
    poration that would render a separate election under
    § 12-391 (f) (2) superfluous. See, e.g., Allen v. Commis-
    sioner of Revenue 
    Services, supra
    , 
    324 Conn. 309
    (‘‘stat-
    utes shall not be construed to render any sentence,
    clause, or phrase superfluous or meaningless’’ [internal
    quotation marks omitted]). Accordingly, we conclude
    that the plain language of the statute, when read in
    context with other related provisions, clearly provides
    that the assets contained within the trusts at issue are
    includable in the decedent’s gross estate pursuant to
    § 12-391 (c) (3) because they were included in the dece-
    dent’s gross estate for federal estate tax purposes.
    Not advancing a textual basis for their construction
    of the provision, the plaintiffs rely principally upon case
    law for their claim that the federal estate tax code is
    incorporated into § 12-391 (c) (3). At first blush, our
    holding in Berkley v. Gavin, 
    253 Conn. 761
    , 772–75, 
    756 A.2d 248
    (2000), would appear to strongly support the
    plaintiffs’ position in the present case. In Berkley, the
    issue was whether the phrase ‘‘as determined for federal
    income tax purposes’’ in the statute defining adjusted
    gross income; General Statutes (Rev. to 1999) § 12-701
    (a) (19); ‘‘means as determined in accordance with fed-
    eral income tax methodology, or as reported on a tax-
    payer’s federal income tax return.’’ Berkley v. 
    Gavin, supra
    , 772. Relying on case law, this court held that the
    phrase meant the former because the pertinent federal
    tax provisions for determining adjusted gross income
    were incorporated into this state’s income tax provi-
    sions. 
    Id., 774. This
    included the tax benefit rule. 26
    U.S.C. § 111.10 As a result, whether certain recovered
    losses were included in Connecticut adjusted gross
    income in the present year would depend on whether
    the taxpayer had reduced his state income tax liability,
    but not necessarily his federal income tax liability, in
    a previous year as a result of such previously reported
    losses. In essence, the incorporation of the federal tax
    benefit rule resulted in a ‘‘Connecticut tax benefit rule
    . . . .’’ (Emphasis in original.) 
    Id., 783 (Sullivan,
    J.,
    dissenting).11 This is precisely the interpretation the
    plaintiffs seek in the present case—namely, that the
    inclusion of a QTIP marital deduction trust in a dece-
    dent’s state gross estate requires the state to have
    granted a corresponding deduction to the estate of the
    first to die spouse. Justice Sullivan, in his dissent in
    Berkley, pointed out that the result reached by the
    majority in that case was inconsistent with the plain
    language of the statute because such a modification of
    Connecticut adjusted gross income was not ‘‘for federal
    income tax purposes . . . .’’ (Internal quotation marks
    omitted.) 
    Id., 784. Indeed,
    as a result of the holding
    in Berkley, the legislature subsequently clarified the
    definition of adjusted gross income by adding the
    phrase ‘‘and as properly reported on such person’s fed-
    eral income tax return.’’ Public Acts, Spec. Sess., June,
    2001, No. 01-6, § 35; see also Public Acts, Spec. Sess.,
    June, 2001, No. 01-6, § 36 (stating legislative intent).
    To construe the provision defining gross estate in the
    present case to incorporate the federal estate tax code
    would result, as Justice Sullivan pointed out in Berkley,
    in a construction inconsistent with the plain language
    of the relevant statute. We conclude, especially in light
    of the principles of § 1-2z, which was not in effect when
    Berkley was decided, that incorporation of federal tax
    statutes into our statutory provisions should be deter-
    mined in the first instance with reference to the plain
    meaning of § 12-391 (c) (3).
    Next, we disagree with the plaintiffs’ contention that
    our holding in New York Trust Co. v. Doubleday, 
    144 Conn. 134
    , 145, 
    128 A.2d 192
    (1956), incorporated all
    provisions of the federal estate tax into our estate tax
    code. In that case, we stated the following ‘‘The Con-
    necticut estate tax statute . . . adopts as the base for
    computing the tax 80 [percent] of the amount of the
    basic federal estate tax. Inferentially, then, our statute
    incorporates within itself the provisions of the federal
    estate tax statute, governing the computation of the
    federal estate tax, including all of the provisions of the
    latter statute for exemptions and deductions.’’ 
    Id. The estate
    tax statute at issue in that case bears no resem-
    blance to the estate tax at issue in the present case.12
    The previous estate tax, known as the pick up tax,
    was principally based upon the federal credit available
    under 26 U.S.C. § 2011. See G. Wilhelm & L. Weintraub,
    Connecticut Estate Practice: Death Taxes in Connecti-
    cut (4th Ed. 2013) § 1:2, p. 1-6. Under the previous estate
    tax, ‘‘[t]he amount of the tax was the amount by which
    such credit exceeded the total amount of all death taxes,
    including the Connecticut succession tax, actually paid
    to the several states and territories.’’ 
    Id., pp. 1-6
    through
    1-7. We described our estate tax at that time as one
    that did ‘‘no more than to divert into the state treasury
    what would otherwise be taken by the federal govern-
    ment as a part of the federal estate tax.’’ New York
    Trust Co. v. 
    Doubleday, supra
    , 145. After Congress
    repealed the state death tax credit,13 the legislature
    enacted a new, stand alone estate tax applicable to
    decedents dying on or after January 1, 2005. See Public
    Acts 2005, No. 05-251, § 69. The decedent’s estate is
    being taxed under the present, stand-alone estate tax,
    not the pick up tax. Accordingly, we construe the pres-
    ent estate tax statute anew, unbound by this court’s
    construction of a substantively different and inopera-
    tive tax statute.
    In sum, we conclude that the value of the QTIP marital
    deduction trusts at issue in the present case are
    included in the decedent’s gross estate for Connecticut
    estate tax purposes because those assets are included
    in the decedent’s gross estate for federal estate tax
    purposes.
    III
    We next address the plaintiffs’ claim that § 12-391
    does not permit the defendant to tax the assets con-
    tained within the QTIP marital deduction trusts because
    the decedent did not own the property subject to the
    tax. In particular, the plaintiffs claim that the statutory
    language in effect at the time of the decedent’s death;
    General Statutes (Rev. to 2009) § 12-391 (d) (3);14 limits
    the authority of the defendant to impose a tax upon
    intangible personal property to only such property
    owned by the decedent and that, therefore, the assets
    contained within the trusts at issue are not taxable. The
    defendant claims that No. 13-247, § 120, of the 2013
    Public Acts (P.A. 13-247), and No. 14-155, § 12, of the
    2014 Public Acts (P.A. 14-155), clarified the original
    intention of the legislature with respect to the meaning
    of the relevant provision and, therefore, applies retroac-
    tively. Specifically, P.A. 13-247, § 120, amended § 12-
    391 (d) (3) to, inter alia, replace the words ‘‘owned by
    the decedent’’ with ‘‘included in the gross estate of the
    decedent,’’ and P.A. 14-155, § 12, expressly declared the
    legislative intent of P.A. 13-247, § 120, to be ‘‘clarifying
    in nature and applicable to all open estates.’’ The defen-
    dant points to the legislative history of both acts in
    support of his claim. The plaintiffs counter that, not-
    withstanding the legislature’s belated attempt in P.A.
    14-155 to declare its intent regarding the amendments,
    P.A. 13-247 amounted to a substantive change to the
    law that can only be applied prospectively. As evidence,
    the plaintiffs point to the effective date of January 1,
    2013, contained in P.A. 13-257, § 120. The plaintiffs fur-
    ther claim that if § 12-391 (d) (3) were construed in
    accordance with its plain meaning, it would be evident
    that the amendment amounted to a substantive change.
    The plaintiffs also dispute that the legislative history is
    sufficient to support the conclusion that the amendment
    was clarifying in nature. We agree with the defendant.
    We begin by discussing the legal standard we apply in
    determining whether the legislature intended statutory
    amendments to be clarifying in nature. ‘‘We presume
    that, in enacting a statute, the legislature intended a
    change in existing law. . . . This presumption, like any
    other, may be rebutted by contrary evidence of the
    legislative intent in the particular case. An amendment
    which in effect construes and clarifies a prior statute
    must be accepted as the legislative declaration of the
    meaning of the original act. . . . Furthermore, an
    amendment that is intended to clarify the intent of an
    earlier act necessarily has retroactive effect.’’ (Citation

    Hospital v.

    of statutory construction, we need not construe the
    original statutory language upon finding that subse-
    quent legislation is clarifying in nature. See

    ‘‘To determine whether the legislature enacted a stat-
    utory amendment with the intent to clarify existing
    legislation, we look to various factors, including, but
    not limited to (1) the amendatory language . . . (2) the
    declaration of intent, if any, contained in the public act
    . . . (3) the legislative history . . . and (4) the circum-
    stances surrounding the enactment of the amendment,
    such as, whether it was enacted in direct response to
    a judicial decision that the legislature deemed incorrect

    statutory ambiguity . . . .’’ (Citations omitted; internal

    ronmental Protection, 
    283 Conn. 156
    , 174, 
    927 A.2d 793
    (2007). Not each factor is given equal weight. We have
    previously observed that the legislature ‘‘simplifie[s]
    our task of determining its intention in adopting [amen-
    datory legislation] by incorporating into the text of the
    act an explicit statement of the legislature’s intention.’’
    Greenwich Hospital v. 
    Gavin, supra
    , 
    265 Conn. 519
    .
    First and foremost, the legislature enacted express
    language manifesting its intention to clarify its original
    intent with respect to the relevant provision. Section
    12 of P.A. 14-155 provides in relevant part: ‘‘It is the
    intent of the General Assembly that the amendments
    made by section 120 of public act 13-247 to subsections
    (d) and (e) of section 12-391 of the general statutes, as
    amended by this act, are clarifying in nature and apply
    to all open estates.’’ The plaintiffs concede that such
    expressions of legislative intent are often taken as con-
    clusive evidence of original legislative intent.
    Nevertheless, the plaintiffs rightfully point out that,
    when the legislature enacted P.A. 13-247, § 120, it made
    the provision applicable to the estates of decedents
    dying after January 1, 2013.16 The plaintiffs argue that
    the express declaration of intent to clarify should not
    be given effect because it directly conflicts with the
    effective date of P.A. 13-247, § 120, and there is no other
    evidence that the legislature intended that amendment
    to be clarifying. Contrary to the plaintiffs’ claim, the
    legislative history of P.A. 13-247, § 120, does support
    the conclusion that the amendatory language was, in
    fact, clarifying in nature. To be sure, the legislative
    history is scant, but it points in favor of the defendant.
    Senator John W. Fonfara, in response to a question
    from Senator L. Scott Frantz, remarked that the revision
    to the estate tax statute is ‘‘technical and is consistent
    with how we’ve always implemented this procedure so
    it doesn’t change the way Connecticut has implemented
    this provision previously.’’ 56 S. Proc., Pt. 17, 2013 Sess.,
    p. 5459.17 We have previously recognized that testimony
    in which amendatory language is described as technical
    tends to support the conclusion that the legislature
    intended the language to be clarifying. See Greenwich
    Hospital v. 
    Gavin, supra
    , 
    265 Conn. 523
    . Additionally,
    it is not disputed that the claims made by the plaintiffs
    in the present case, as well as other taxpayers, were the
    impetus behind P.A. 13-247, § 120. Thus, the amendment
    ‘‘invokes the principle of statutory construction that [i]f
    the amendment was enacted soon after controversies
    arose as to the interpretation of the original act, it is
    logical to regard the amendment as a legislative inter-
    pretation of the original act . . . .’’ (Internal quotation
    marks omitted.) State v. Blasko, 
    202 Conn. 541
    , 558, 
    522 A.2d 753
    (1987); see also Caron v. Inland Wetlands &
    Watercourses Commission, 
    222 Conn. 269
    , 279, 
    610 A.2d 584
    (1992).
    Finally, the plaintiffs claim that the plain meaning of
    the term ‘‘owned by’’ in General Statutes (Rev. to 2009)
    § 12-391 operated as a substantive limitation on the
    state’s authority to levy the estate tax on certain prop-
    erty included in the gross estate. Thus, according to
    the plaintiffs, notwithstanding the legislature’s declara-
    tion of intent in P.A. 14-155, § 12, the amendatory lan-
    guage in P.A. 13-247, § 120, broadened the class of
    intangible personal property subject to the estate tax
    and, thereby, effected a substantive change to the law
    that must be applied prospectively. We acknowledge
    that, at some point, a change in the law is so substantial
    that, no matter how forcefully the legislature expresses
    its intent to clarify, the change must be regarded as
    substantive. See State v. 
    Blasko, supra
    , 
    202 Conn. 558
    (‘‘[t]he legislature could not, even by extensive protesta-
    tions of legislative intent, convert an act that is truly
    curative into one that is effectively clarifying’’). Never-
    theless, the plaintiffs have failed to persuade us to dis-
    count the clear expression of legislative intent in the
    present case.18 First, this is not a case in which the
    legislature ‘‘attempt[ed] to clothe a retroactive substan-
    tive change in clarifying garb by, for example,
    attempting to ‘clarify’ the meaning of a statute to mean
    something different from a court’s repeated and consis-
    tent interpretation of the same statute.’’ Connecticut
    National Bank v. Giacomi, 
    242 Conn. 17
    , 44 n.33, 
    699 A.2d 101
    (1997). Furthermore, it is far from clear that the
    ordinary meaning of ‘‘owned by’’ furnished the proper
    statutory construction when that language was opera-
    tive. A narrow construction of the phrase ‘‘owned by’’
    would arguably operate to prevent the state from ever
    levying the estate tax upon any qualifying life interest—
    whether the property is included in the gross estate
    because the decedent held a federally qualifying life
    interest in a trust under § 12-391 (c) (3) or a state qualify-
    ing life interest under § 12-391 (f) (2)—because, as the
    plaintiffs urge, the surviving spouse did not own the
    trust assets in which he or she enjoyed the life interest.
    Thus, we reject the plaintiffs’ claim that the amendment
    effected such a significant change to the law that the
    only conclusion to be drawn, notwithstanding a declara-
    tion of express legislative intent to the contrary, is that
    the change was substantive. The effective date indi-
    cated in P.A. 13-247, § 120, is an outlier among all the
    evidence that points to the conclusion that the amenda-
    tory language was clarifying in nature. Accordingly, we
    conclude that P.A. 13-247, § 120, is clarifying in nature
    and, therefore, necessarily applies retroactively to the
    decedent’s estate in the present case.
    The plaintiffs also claim that retroactive application
    of the amended statute to the estate of the decedent
    would result in a violation of the due process clause
    of the fourteenth amendment to the United States con-
    stitution. This claim fails because the amendment was
    not a substantive change to the law. Connecticut
    National Bank v. 
    Giacomi, supra
    , 
    242 Conn. 44
    . ‘‘The
    necessarily retroactive effect of clarifying legislation
    is not to be confused with the retroactive effect of
    legislation that changes the law. The former clarifies
    the substantive provisions to which a person has always
    been subject. The latter applies substantive provisions
    to a person heretofore not subject to those provisions.’’
    
    Id. To the
    extent that clarifying legislation must satisfy
    the rational basis test set forth in United States v. Carl-
    ton, 
    512 U.S. 26
    , 30–31, 
    114 S. Ct. 2018
    , 
    129 L. Ed. 2d 22
    (1994), because the legislature merely clarified its
    intent when enacting the Connecticut estate tax, the
    application of P.A. 13-257, § 120, to the present case
    clearly satisfies the rational basis test. See Bhinder v.
    Sun 
    Co., supra
    , 
    263 Conn. 374
    . Accordingly, we reject
    the plaintiffs’ claim that the retroactive application of
    the amendment to the decedent’s estate violates due
    process.
    IV
    Lastly, we address the issue of whether, at the death
    of the decedent, a transfer of the assets contained within
    the QTIP marital deduction trusts occurred such that
    it was proper to levy the estate tax based on the value
    of those assets. By its terms, the Connecticut estate tax
    is a tax ‘‘imposed upon the transfer of the estate of
    each person who at the time of death was a resident
    of this state.’’ (Emphasis added.) General Statutes § 12-
    391 (d) (1) (B). The plaintiffs claim that no transfer
    occurs at the death of a life beneficiary of a QTIP marital
    deduction trust; rather, a ‘‘deemed’’ or ‘‘fictional’’ trans-
    fer occurs in order to collect the tax that was deferred
    when the actual taxable transfer was made at the death
    of the first to die spouse. In other words, because Con-
    necticut did not defer imposition of the estate tax upon
    Everett’s actual transfer of assets into the trusts when
    he died in Florida, it cannot now properly tax the ‘‘fic-
    tional’’ transfer of those assets from the decedent’s
    estate. As a result, according to the plaintiffs, the impo-
    sition of the estate tax on the decedent’s estate in the
    present case results in an impermissible tax upon an
    out-of-state transfer in violation of the due process
    clause of the fourteenth amendment. The defendant
    claims that the Connecticut estate tax is properly levied
    upon the transfer of the QTIP trust assets at the dece-
    dent’s death. The defendant maintains that a transfer
    can be characterized by the shift in legal relationships
    to property occasioned by death, and a tax on such
    shifts is a proper excise tax within the state’s taxing
    authority. In turn, because the decedent was a domicili-
    ary of the state at her death, the defendant maintains
    that imposing the tax on this transfer comports with
    the due process clause. We agree with the defendant.
    The underlying basis for the assets of these trusts
    being included in the decedent’s gross estate is that
    those assets qualified as QTIP under the federal tax
    code. See part II of this opinion. But in order to be very
    clear, we set aside the fictions of the QTIP provisions.
    The defendant seeks to levy the estate tax on certain
    assets in which the decedent enjoyed a life interest.
    The issue that we must resolve is whether the defendant
    may impose the estate tax based on the value of trust
    assets in which a decedent enjoyed only a life interest.
    As an initial matter, it is clear that the legislature
    intended ‘‘transfer’’ to be construed as broadly as possi-
    ble. As the discussion in part II of this opinion demon-
    strates, the legislature intended for all property in the
    federal gross estate to be included in the state gross
    estate. See General Statutes § 12-391 (c) (3). Second,
    as the discussion in part III of this opinion demon-
    strates, § 12-391 (d) (3), as amended, reveals a clear
    legislative intent to calculate and levy the estate tax
    upon all intangible personal property included in the
    gross estate to the greatest extent permitted by the
    federal constitution. It would be illogical for the legisla-
    ture to have called for the inclusion of QTIP marital
    deduction trusts in the gross estate of the decedent,
    but also have intended a narrow definition of ‘‘transfer’’
    that would operate to prevent the defendant from levy-
    ing the tax on the value of such property. Accordingly,
    ‘‘transfer’’ must be construed to embrace the shifting
    in relationships to property attendant to the death of
    a life beneficiary.
    The crux of the plaintiffs’ statutory claims in the
    present case is that the defendant’s construction of
    the estate tax statute results in the imposition of an
    unconstitutional tax upon the decedent’s estate. The
    plaintiffs are correct ‘‘that this court has a duty to con-
    strue statutes, whenever possible, to avoid constitu-
    tional infirmities . . . .’’ (Internal quotation marks
    omitted.) State v. Cook,

    Id. Accordingly, we
    turn to the issue
    of whether this construction of the estate tax statute
    is constitutionally infirm.
    We first set forth the appropriate standard of review.
    ‘‘With respect to a statutory challenge on constitutional
    grounds, [a] validly enacted statute carries with it a
    strong presumption of constitutionality, [and] those
    who challenge its constitutionality must sustain the
    heavy burden of proving its unconstitutionality beyond
    a reasonable doubt. . . . The court will indulge in
    every presumption in favor of the statute’s constitution-
    ality . . . . Therefore, [w]hen a question of constitu-
    tionality is raised, courts must approach it with caution,
    examine it with care, and sustain the legislation unless
    its invalidity is clear. . . . In other words, we will
    search for an effective and constitutional construction
    that reasonably accords with the legislature’s underly-
    ing intent.’’ (Citation omitted; internal quotation marks

    ,

    (1900).
    A proper excise or estate tax, however, is levied not only
    upon literal transfers at death. Rather, any ‘‘creation,
    exercise, acquisition, or relinquishment of any power
    or legal privilege which is incident to the ownership of
    property’’ at the death of the decedent is subject to tax
    as a transfer at death. Fernandez v. 
    Wiener, supra
    , 352.19
    In other words, a sovereign may tax the transmutation
    of legal rights in property occasioned by death. See 
    id., 358 (‘‘[w]e
    find no basis for the contention that the tax
    is arbitrary and capricious because it taxes transfers
    at death and also the shifting at death of particular
    incidents of property’’); see also United States Trust
    Co. v. 
    Helvering, supra
    , 60 (‘‘[the estate tax] is an excise
    imposed upon the transfer of or shifting in relationships
    to property at death’’).
    In Fernandez, the heirs of the decedent challenged,
    on various federal constitutional grounds, the imposi-
    tion of the estate tax on the one-half share of marital
    community property owned by a surviving spouse at
    the death of the decedent. Fernandez v. 
    Wiener, supra
    ,
    
    326 U.S. 346
    –47. The heirs had argued that, at the dece-
    dent’s death, the surviving spouse ‘‘acquire[d] no new
    or different interest in the property’’ and the death of
    neither spouse ‘‘operate[d] to transfer, relinquish or
    enlarge any legal or economic interest in the property
    of the other spouse.’’ 
    Id., 346. The
    court rejected the
    heirs’ claims, noting that, notwithstanding the fact that
    the surviving spouse’s rights were vested, the surviving
    spouse was liberated of the burdens of the decedent’s
    rights over the survivor’s share and enjoyed greater
    rights in the property. 
    Id., 355–56. The
    court summa-
    rized that, ‘‘[i]t is enough that death brings about
    changes in the legal and economic relationships to the
    property taxed, and the earlier certainty that those
    changes would occur does not impair the legislative
    power to recognize them, and to levy a tax on the
    happening of the event which was their generating
    source.’’ 
    Id., 356–57. We
    conclude that taxing the assets contained within
    the QTIP marital deduction trusts upon the death of
    the decedent in the present case fits comfortably with
    the general principles set forth in Fernandez. The termi-
    nation of the decedent’s beneficial life interest in those
    assets, and the remainder beneficiaries coming into pos-
    session and enjoyment of their successive interests, is
    a sufficient ‘‘shifting at death of particular incidents of
    property’’ to properly impose an excise tax. 
    Id., 358. The
    plaintiffs’ claim that the reasoning of Coolidge
    v. Long, 
    282 U.S. 582
    , 
    51 S. Ct. 306
    , 
    75 L. Ed. 562
    (1931),
    compels the conclusion that a properly taxable transfer
    of property does not occur when, at the death of the
    decedent, the decedent’s life interest in the property
    terminates. In that case, before the operative state suc-
    cession tax law took effect, the decedent executed a
    trust declaration reserving for herself and her spouse
    life interests in certain property with remainders to take
    effect in possession upon the death of the surviving
    spouse. 
    Id., 593–94. The
    operative statute in that case
    subjected to a tax ‘‘[a]ll property . . . which shall pass
    by . . . deed, grant or gift . . . made or intended to
    take effect in possession or enjoyment after [the grant-
    or’s] death . . . .’’ (Internal quotation marks omitted.)
    
    Id., 595. The
    United States Supreme Court rebuffed
    the Massachusetts Supreme Judicial Court’s conclusion
    that the death of the survivor of the settlors of the trust
    was a ‘‘taxable commodity under the statute enacted
    after the creation of the trust,’’ and held that the tax
    was an unconstitutional retroactive tax under the due
    process clause of the fourteenth amendment and the
    contract clause. 
    Id., 595–99. The
    court reasoned that
    the grant of the remainder to each of the beneficiaries
    was ‘‘a grant in praesenti,’’ to be enjoyed at the death
    of the surviving spouse. 
    Id., 597. The
    court stated that
    the provision of income for the life of the settlors ‘‘did
    not operate to postpone the vesting in the sons of the
    right of possession or enjoyment,’’ and the trustees were
    bound to turn over the property at the death of the
    survivor. 
    Id. Thus, the
    decedent’s death was not the
    ‘‘generating source of any right in the remaindermen.
    . . . There was no transmission then.’’ (Citation omit-
    ted.) 
    Id., 597–98. ‘‘The
    succession, when the time came,
    did not depend upon any permission or grant of the
    [c]ommonwealth.’’ 
    Id., 598. The
    reasoning of that case
    does not, however, alter our conclusion in the pres-
    ent case.
    First, the United States Supreme Court has sharply
    criticized cases that, like Coolidge v. 
    Long, supra
    , 
    282 U.S. 598
    , were ‘‘decided during an era characterized
    by exacting review of economic legislation under an
    approach that ‘has long since been discarded.’ ’’ United
    States v. 
    Carlton, supra
    , 
    512 U.S. 34
    , quoting Ferguson
    v. Skrupa, 
    372 U.S. 726
    , 730, 
    83 S. Ct. 1028
    , 
    10 L. Ed. 2d 93
    (1963). In fact, in Carlton, the United States Supreme
    Court specifically referred to Nichols v. Coolidge, 
    274 U.S. 531
    , 
    47 S. Ct. 710
    , 
    71 L. Ed. 1184
    (1927), in its
    criticism of case law from that era. That case involved
    application of the federal estate tax to the very same
    trust at issue in Coolidge v. 
    Long, supra
    , 582. The court’s
    conclusion in Coolidge v. 
    Long, supra
    , 597–98, hinged
    on the fact that the trust deed was a present grant that
    resulted in ‘‘vested’’ rights in the beneficiaries. Vested
    rights no longer form the touchstone of the analysis of
    economic regulation. See Honeywell, Inc. v. Minnesota
    Life & Health Ins. Guaranty Assn., 
    110 F.3d 547

    (1905)] era’s strict protection of economic
    freedom and vested rights’’). The court in Fernandez
    clearly subordinated the fact that the surviving spouse’s
    rights were vested to the practical legal and economic
    shift occasioned by the decedent. Fernandez v. 
    Wiener, supra
    , 
    326 U.S. 356
    .20
    It is clear from the reasoning in Fernandez that the
    court embraced a broader concept of transfer than
    when the court considered Coolidge v. 
    Long, supra
    , 
    282 U.S. 582
    . The court in Coolidge v. 
    Long, supra
    , 597,
    reasoned that the death of the settlor was not the ‘‘gen-
    erating source of any right in the remaindermen.’’ In
    Fernandez v. 
    Wiener, supra
    , 
    326 U.S. 356
    –57, the court
    took a more practical approach and looked not to
    whether death was the generating source of ‘‘rights,’’
    but rather whether death was the generating source of
    ‘‘changes in the legal and economic relationships to the
    property taxed . . . .’’ This more encompassing lan-
    guage employed by the court reflects its embrace of an
    evaluation of the practical economic and legal shifts
    occasioned by death rather than a reliance of formalistic
    property law distinctions in determining whether a
    properly taxable transfer has occurred.
    To the extent the reasoning of Coolidge v. 
    Long, supra
    , 
    282 U.S. 582
    , survives, the case can be distin-
    guished by the type of tax at issue. In that case, the
    statute imposed a tax on a grant in trust to take effect
    at the death of the settlor or the settlor’s surviving
    spouse. See 
    id., 595–96. Put
    more simply, the statute,
    by its terms, taxed the transfer in trust of the property.
    In the present case, the statute does not purport to tax
    the transfer of assets from Everett; rather, the statute
    taxes property in which the decedent had a federally
    qualifying life interest. See 26 U.S.C. § 2044 (a); General
    Statutes § 12-391 (c) (3). The tax in the present case is
    directly targeting the changes in legal and economic
    relationships to the property, not a prior transfer.
    Finally, Coolidge v. 
    Long, supra
    , 
    282 U.S. 582
    , was
    decided long before the evolution of state and federal
    tax schemes that employ complex fictions designed
    to effectuate certain public policy—such as treating a
    married couple as a single economic unit—while ensur-
    ing that such tax schemes do not form apertures
    through which it would be possible to avoid taxation.
    In order to effectuate social and economic policy, legis-
    lators have crafted ever more complex tax laws than
    those that simply tax the transfer of title to property
    at death. For example, one court described the concept
    of QTIP as one that had been invented by Congress
    ‘‘[o]ut of thin air and from whole cloth,’’ noting that
    ‘‘[i]f unlimiting the [m]arital [d]eduction was a flight
    into the wild blue yonder, Congress truly slipped the
    surly bonds of earth with the advent of QTIP.’’ (Foot-
    note omitted; internal quotation marks omitted.) Estate
    of Clayton v. Commissioner of Internal 
    Revenue, supra
    , 
    976 F.2d 1493
    . Connecticut, too, seeks to impose
    the estate tax when federally qualified terminable inter-
    est property leaves the marital unit, irrespective of
    whether this state, another state, or no state deducted
    the value of that property from the taxable estate of
    the first to die spouse. ‘‘Nothing can be less helpful
    than for courts to go beyond the extremely limited
    restrictions that the [c]onstitution places upon the
    states and to inject themselves in a merely negative
    way into the delicate processes of fiscal [policymaking].
    We must be on guard against imprisoning the taxing
    power of the states within formulas that are not com-
    pelled by the [c]onstitution . . . .’’ (Emphasis added.)
    Wisconsin v. J. C. Penney Co., 
    311 U.S. 435
    , 445, 61 S.
    Ct. 246, 
    85 L. Ed. 267
    (1940). ‘‘The [c]onstitution is
    not a formulary. It does not demand of states strict
    observance of rigid categories nor precision of technical
    phrasing in their exercise of the most basic power of
    government, that of taxation.’’ 
    Id., 444. In
    sum, we would
    conclude that Coolidge v. 
    Long, supra
    , 582, does not
    foreclose the defendant from taxing the assets within
    the QTIP marital deduction trusts at issue in the estate
    of the decedent as a transfer.
    The plaintiffs’ claim that the tax in the present case
    violates the fourteenth amendment as a tax on out-of-
    state property is also unavailing. It is well settled that
    ‘‘[t]he due process clause denies to the state power
    to tax or regulate the [entity’s] property and activities
    elsewhere.’’ (Internal quotation marks omitted.) Allen
    v. Commissioner of Revenue 
    Services, supra
    ,

    . With respect to the transfer of real and tangible
    personal property, the constitutional rule is simple—
    namely, the state in which the property has an actual
    situs has the exclusive jurisdiction to levy a tax.
    Treichler v. Wisconsin, 
    338 U.S. 251
    , 256–57, 
    70 S. Ct. 1
    , 
    94 L. Ed. 37
    (1949); Frick v. Pennsylvania,

    , 487–88, 
    45 S. Ct. 603
    , 
    69 L. Ed. 1058
    (1925). The
    plaintiffs’ claim that the rule in those cases as applied to
    the trusts in the present case stretches the rule too far.
    Unlike real and personal property, intangible per-
    sonal property is characterized by ‘‘legal relationships
    between persons and which in fact have no geographi-
    cal location . . . .’’ Graves v. Schmidlapp, 
    315 U.S. 657
    ,
    660, 
    62 S. Ct. 870
    , 
    86 L. Ed. 1097
    (1942). For this reason,
    ‘‘intangibles themselves have no real situs . . . .’’

    493, 
    67 S. Ct. 1400
    , 
    91 L. Ed. 1621
    (1947). Accordingly,
    the rule of situs is not controlling with respect to the
    issue of jurisdiction to levy the estate tax upon intangi-
    ble personal property. Curry v. McCanless, 
    307 U.S. 357
    , 369–70, 
    59 S. Ct. 900
    , 
    83 L. Ed. 1339
    (1939). The
    proper inquiry with respect to the jurisdiction to levy
    the estate tax on intangibles is whether ‘‘by the practical
    operation of a tax the state has exerted its power in
    relation to opportunities which it has given, to protec-
    tion which it has afforded, to benefits which it has
    conferred by the fact of being an orderly, civilized soci-
    ety.’’ (Internal quotation marks omitted.) State Tax

    , 
    86 L. Ed. 1358
    (1942), quoting Wisconsin
    v. J. C. Penney 
    Co., supra
    , 
    311 U.S. 444
    . The state’s
    authority to impose a tax is at its apogee with respect to
    a domiciliary. ‘‘From the beginning of our constitutional
    system control over the person at the place of his domi-
    cile and his duty there, common to all citizens, to con-
    tribute to the support of government have been deemed
    to afford an adequate constitutional basis for imposing
    on him a tax on the use and enjoyment of rights in
    intangibles measured by their value.’’ Curry v. McCan-
    
    less, supra
    , 366.
    Under these principles, we conclude that Connecticut
    did not lack jurisdiction to tax the transfer of the assets
    contained within the QTIP marital deduction trust as
    part of the decedent’s estate. The decedent was a domi-
    ciliary of this state at the time of her death. She enjoyed
    all of the benefits of the state attendant to residence
    therein. During that time, she enjoyed the economic
    benefits of her beneficial life interest in the trusts. This
    nexus is sufficient for due process.21 Accordingly, we
    conclude that the imposition of the estate tax on the
    transfer of the assets contained within relevant trusts
    did not violate due process.
    To summarize, we conclude that the trial court prop-
    erly rendered summary judgment in favor of the defen-
    dant because the defendant properly included the value
    of the assets contained within the QTIP marital deduc-
    tion trusts in the decedent’s gross estate and levied
    the estate tax thereupon in accordance with § 12-391
    without violating due process.
    The judgment is affirmed.
    In this opinion the other justices concurred.

    The coexecutors are Dorothy Newberth, Nancy B. Jackman, and David

    the estate of Helen B. Brooks, the present action is maintained on its behalf
    by the coexecutors. See Estate of Rock v. University of Connecticut, 
    323 Conn. 26
    , 32, 
    144 A.3d 420

    of the present case for the sake of consistency with the trial court’s memoran-

    The plaintiffs appealed from the judgment of the trial court to the Appel-

    Statutes § 51-199 (c) and Practice Book § 65-1.

    Everett’s estate elected to separate the trust set forth in Everett’s will
    into two parts in order to allocate a portion of the generation skipping tax
    exemption to part of the trust. See 26 U.S.C. § 2652 (a) (3) (2000). Neither
    the separation of the trust into two parts nor the generation skipping tax
    exemption allocation affects the resolution of this appeal.
    4
    Specifically, Everett’s will provided in relevant part: ‘‘During the life of
    my wife my trustee or trustees other than my wife may encroach upon the
    principal of this residuary trust for her benefit from time to time and pay
    any portions or all thereof to her or apply the same to her use, if such
    trustees in such trustees’ uncontrolled discretion shall deem the same to
    be desirable for any reason, and this discretion shall expressly include the
    power to terminate this trust by such encroachments. It shall not be neces-
    sary for such trustees to inquire as to any other income or property of my
    said wife. Any decision of such trustees with respect to the exercise of said
    discretionary power, made in good faith, shall fully protect such trustees,
    and shall be conclusive and binding upon all interested persons. . . .’’
    5
    The general marriage deduction provision, which is set forth in 26 U.S.C.
    § 2056 (a), provides: ‘‘For purposes of the tax imposed by section 2001, the
    value of the taxable estate shall, except as limited by subsection (b), be
    determined by deducting from the value of the gross estate an amount equal
    to the value of any interest in property which passes or has passed from
    the decedent to his surviving spouse, but only to the extent that such interest
    is included in determining the value of the gross estate.’’
    6
    We note, in particular, that 26 U.S.C. § 2056 (b) (7) (B) provides: ‘‘Quali-
    fied terminable interest property defined
    ‘‘For purposes of this paragraph—
    ‘‘(i) In general
    ‘‘The term ‘qualified terminable interest property’ means property—
    ‘‘(I) which passes from the decedent,
    ‘‘(II) in which the surviving spouse has a qualifying income interest for
    life, and
    ‘‘(III) to which an election under this paragraph applies.
    ‘‘(ii) Qualifying income interest for life
    ‘‘The surviving spouse has a qualifying income interest for life if—
    ‘‘(I) the surviving spouse is entitled to all the income from the property,
    payable annually or at more frequent intervals, or has a usufruct interest
    for life in the property, and
    ‘‘(II) no person has a power to appoint any part of the property to any
    person other than the surviving spouse.
    ‘‘Subclause (II) shall not apply to a power exercisable only at or after the
    death of the surviving spouse. To the extent provided in regulations, an
    annuity shall be treated in a manner similar to an income interest in property
    (regardless of whether the property from which the annuity is payable can
    be separately identified).
    ‘‘(iii) Property includes interest therein
    ‘‘The term ‘property’ includes an interest in property.
    ‘‘(iv) Specific portion treated as separate property
    ‘‘A specific portion of property shall be treated as separate property.
    ‘‘(v) Election
    ‘‘An election under this paragraph with respect to any property shall be
    made by the executor on the return of tax imposed by section 2001. Such
    an election, once made, shall be irrevocable.’’

    Section 2519 (a) of title 26 of the United States Code provides: ‘‘For
    purposes of this chapter and chapter 11, any disposition of all or part of a
    qualifying income interest for life in any property to which this section
    applies shall be treated as a transfer of all interests in such property other
    than the qualifying income interest.’’
    8
    Section 2044 of title 26 of the United States Code provides in relevant
    part as follows: ‘‘(a) General rule
    ‘‘The value of the gross estate shall include the value of any property to
    which this section applies in which the decedent had a qualifying income
    interest for life. . . .
    ‘‘(c) Property treated as having passed from decedent
    ‘‘For purposes of this chapter and chapter 13, property includible in the
    gross estate of the decedent under subsection (a) shall be treated as property
    passing from the decedent.’’
    9
    As discussed in part III of this opinion, the legislature has made certain
    amendments to § 12-391 that are relevant to the present appeal. See Public
    Acts 2013, No. 13-247, § 120; Public Acts 2014, No. 14-155, § 12. We note,
    however, the subdivisions discussed in this section, namely § 12-391 (c) (3)
    and (f) (2), have remained unchanged since the death of the decedent. For
    the sake of simplicity, all references to § 12-391 in this opinion, unless
    otherwise noted, are to the current revision of the statute.
    10
    The tax benefit rule, 26 U.S.C. § 111 (a), provides: ‘‘Gross income does
    not include income attributable to the recovery during the taxable year of
    any amount deducted in any prior taxable year to the extent such amount
    did not reduce the amount of tax imposed by this chapter.’’
    11
    In his dissent, Justice Sullivan illustrated the consequence of incorporat-
    ing the tax benefit rule as follows: ‘‘A taxpayer, in year one, incurs a loss
    and receives a federal tax benefit because his income is reduced by that
    loss. For some reason, however, he receives no Connecticut tax benefit
    from the loss. In year two, the taxpayer recovers the loss. The taxpayer
    must pay federal income tax on the recovered income in year two, pursuant
    to the inclusionary aspect of the tax benefit rule. . . . [B]ecause the tax-
    payer received no Connecticut tax benefit in year one, he may exclude
    the recovered income for Connecticut income tax purposes in year two.
    Accordingly, the adjusted gross income reported on the taxpayer’s federal
    income tax return in year two would have to be modified on his Connecticut
    income tax return to reflect the exclusion of the recovered loss for Connecti-
    cut income tax purposes.’’ (Footnote omitted.) Berkley v.

    an actual situs in this state and intangible personal property owned by the
    decedent, regardless of where it is located.’’
    15
    The plaintiffs cite General Statutes §§ 1-1 (u) and 55-3 for the proposition
    that newly enacted legislation shall not affect pending litigation or be applied
    retroactively. These statutes, however, create presumptions against retroac-
    tivity and application to pending litigation, not a per se bar. Gil v. Courthouse

    16
    In a legislative hearing on the relevant provision, the defendant, in
    testimony before the legislature, described P.A. 14-155, § 12, as ‘‘truly techni-
    cal. It overturns a drafting error, a really, truly drafting error of last session
    and restores the intention that [the legislature] had in—in the applicability
    of the estate tax.’’ Conn. Joint Standing Committee Hearings, Finance, Reve-
    nue and Bonding, 2014 Sess., p. 153, remarks of Kevin B. Sullivan, Commis-
    sioner of Revenue Services. We do not, however, accord this testimony
    any weight in our determination of whether the amendments are clarifying
    in nature.
    17
    Whether Senator Fonfara’s testimony pertained to the amendatory lan-
    guage at issue in the present case is the source of disagreement between
    the parties. The Office of Legislative Research, in its bill analysis, described
    P.A. 13-247, § 120, as follows: ‘‘[1] Makes technical changes to how estate
    taxes are calculated for Connecticut residents who have estate property in
    other states. This conforms to current Department of Revenue Services. [2]
    Provides, for both resident and nonresident estates, that the state may
    calculate and levy the tax to the fullest extent permitted by the [United
    States] [c]onstitution.’’ Office of Legislative Research, Bill Analysis for House
    Bill No. 6706, ‘‘An Act Implementing Provisions of the State Budget for the
    Biennium Ending June 30, 2015 Concerning General Government,’’ (2013),
    § 120, available at https://www.cga.ct.gov/2013/BA/2013HB-06706-R00-
    BA.htm (last visited May 4, 2017). The testimony regarding P.A. 13-247, § 120,
    was limited to two questions. The first question, from Senator Kevin C.
    Kelly, related to the first point listed in the bill analysis. 56 S. Proc., supra,
    pp. 5457–58. Senator Fonfara responded that ‘‘the section makes a correction
    that goes back to the decoupling of the state tax from the federal tax and
    . . . preserves the current tax treatment of real and tangible property, which
    Connecticut has jurisdiction to tax.’’ 
    Id., p. 5458.
    Next, Senator Frantz
    inquired about the second point listed in the bill analysis as follows: ‘‘In the
    description of that bill, it says it provides for both residents and nonresident
    estates that the state may calculate and levy the tax to the fullest extent
    permitted by the [United States] [c]onstitution. May I ask . . . what the
    fullest extent . . . permitted by the [United States] [c]onstitution is?’’ 
    Id., p. 5459.
    We understand the second point in the bill analysis as pertaining
    to, inter alia, § 12-391 (d) (3). The purpose set forth in the bill analysis was
    served by amending (d) (3) by substituting the phrase ‘‘owned by’’ with
    ‘‘included in the gross estate of,’’ and adding the following language: ‘‘The
    state is permitted to calculate the estate tax and levy said tax to the fullest
    extent permitted by the [c]onstitution of the United States.’’ P.A. 13-247,
    § 120. The changes ensured that the state could continue to levy the tax to
    the greatest extent permitted by the federal constitution, which according
    to Senator Fonfara is how the state has always implemented the estate tax;
    56 S. Proc., supra, p. 5459; without the risk that a court would strictly
    construe the phrase ‘‘owned by’’ thereby statutorily narrowing the class of
    intangible personal property in the gross estate upon which the state could
    levy the tax. Thus, we understand Senator Fonfara’s response to Senator
    Frantz’ question to implicate all changes to § 12-391 (d) (3), including the
    amendatory language at issue in the present case.
    18
    The plaintiffs’ claim that the fact that the trial court did not first construe
    the original statutory language before concluding that the amendatory lan-
    guage was clarifying in nature amounted to an abdication of judicial responsi-
    bility resulting in a violation of the plaintiffs’ right to separation of powers
    is wholly without merit. First, we note that the plaintiffs have failed to fully
    develop this argument. Specifically, the plaintiffs have failed to cite to a
    single separation of powers case or to explain how their claims fit into our
    separation of powers doctrine. We briefly observe that, the trial court, in
    reaching its conclusion, cited the legislative history of P.A. 13-247, cited the
    express statement of legislative intent in P.A. 14-155, and noted that the
    amendatory language did not amount to a substantial change in the law.
    Resolution of the question of whether amendatory language is clarifying in
    nature does not first require full statutory construction of the original lan-
    guage or a predicate finding of ambiguity. See Middlebury v. Dept. of Envi-
    ronmental 
    Protection, supra
    , 
    283 Conn. 174
    . Rather, courts apply the
    multifactor test set forth and applied in this opinion. Indeed, the plaintiffs
    essentially concede this point in their reply brief by citing Middlebury.
    In short, there was nothing improper about the trial court’s analysis of
    this issue.
    19
    The plaintiffs claim that the fact the decedent had an ownership interest
    in the property was integral to the United States Supreme Court’s analysis
    in Fernandez. Ownership, in the strict sense, was not integral to the analysis.
    See Whitney v. State Tax Commission of New 
    York, supra
    , 
    309 U.S. 538
    (‘‘the state is not confined to that kind of wealth which was, in colloquial
    language, ‘owned’ by a decedent before death’’). As the court in Fernandez
    makes clear, it is the transmutation of rights related to property, not owner-
    ship itself, that is the touchstone of a properly taxable transfer. Fernandez
    v. 
    Wiener, supra
    , 
    326 U.S. 352
    .
    20
    The relative importance the court in Fernandez placed on the fact that
    the surviving spouse’s property rights in that case were vested is revealed
    by the fact the court, in a seemingly scoffing manner, placed the word vested
    in quotation marks. Fernandez v. 
    Wiener, supra
    , 
    326 U.S. 356
    .
    21
    We also note that, at her death, the decedent also served as trustee of
    the QTIP marital deduction trusts. In addition, as noted previously in this
    opinion, she held a limited testamentary power of appointment over the
    trust property. She exercised the power in her will, which was probated in
    Connecticut, to appoint certain property in one of the trusts.
