    The opinion that begins on the next page is a slip opinion. Slip opinions are the
    written opinions that are originally filed by the court.
    A slip opinion is not necessarily the court’s final written decision. Slip opinions
    can be changed by subsequent court orders. For example, a court may issue an
    order making substantive changes to a slip opinion or publishing for precedential
    purposes a previously “unpublished” opinion. Additionally, nonsubstantive edits
    (for style, grammar, citation, format, punctuation, etc.) are made before the
    opinions that have precedential value are published in the official reports of court
    decisions: the Washington Reports 2d and the Washington Appellate Reports. An
    opinion in the official reports replaces the slip opinion as the official opinion of
    the court.
    The slip opinion that begins on the next page is for a published opinion, and it
    has since been revised for publication in the printed official reports. The official
    text of the court’s opinion is found in the advance sheets and the bound volumes

    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    WIGGINS, J.-ln 2013, the legislature amended the Estate and Transfer Tax
    Act, chapter 83.1 00 RCW, in response to our decision in In re Estate of Bracken, 
    175 Wn.2d 549
    , 
    290 P.3d 99
     (2012), in which we narrowly construed the term "transfer."
    The amendment allows the Department of Revenue (DOR) to tax qualified terminable
    interest property (QTIP) as part of a surviving spouse's estate. A QTIP trust is created
    by a deceased spouse and gives the surviving spouse a life interest in the income or
    use of trust property. See 26 U.S.C. § 2056(b )(7)(B)(i)-(ii). The advantage of QTIP
    trusts is that no estate tax is paid on the death of the first spouse; the property is taxed
    only upon the death of the surviving spouse.
    In these consolidated cases, the estates of Hambleton and Macbride
    (collectively Estates) challenge the amendment on a variety of grounds. We reject
    the Estates' challenges and reverse summary judgment in In re Estate of Hambleton,
    No. 89419-1, and affirm the summary judgment in In re Estate of Macbride, No. 89500-
    7.
    Background
    A brief discussion of the history of Washington's current estate tax law, the
    Bracken decision, 
    175 Wn.2d 549
    , and the facts of the consolidated cases, places this
    case in context.
    Washington Estate Tax Law Pre-Bracken
    For many years, Washington did not have an independent estate tax. Instead,
    Washington participated in a federal tax sharing system, referred to as "pickup" taxes.
    2
        In re
    Estate
     of Hambleton,
                            
    No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    Bracken, 175 Wn.2d at 557. Under the pickup tax system, the federal government
    became the principal estate tax collector in exchange for sharing with states a
    generous percentage of the amount collected.          /d.   In 2001, Congress passed
    legislation that gradually eliminated the pickup tax system. /d. at 558. Our legislature
    responded by "revis[ing] existing statutes to tie estate taxation to provisions of the
    Internal Revenue Code as they existed [under the former pickup tax system], with
    DOR continuing to collect the same amount of tax as before." /d. at 558-59. We
    invalidated the revisions and instructed the legislature to either create a stand-alone
    estate tax or remain under the former pickup tax system. /d. at 559; Estate of Hemphill
    v. Dep't of Revenue, 
    153 Wn.2d 544
    , 551, 
    105 P.3d 391
     (2005).
    In 2005, the legislature answered by enacting a stand-alone estate tax, the
    Estate and Transfer Tax Act (Act).     LAWS OF   2005, ch. 516, § 1.   The legislature
    modeled the stand-alone tax after the federal estate tax regime. See Bracken, 175
    Wn.2d at 559. "It incorporates concepts and definitions from federal law and operates
    almost entirely in tandem with taxable estate and tax calculation and reporting for
    federal estate tax purposes."    /d.   For example, the "'Washington taxable estate'
    means the federal taxable estate, less: [specified deductions]."    LAWS OF   2005, ch.
    516, § 2(13).
    Under federal law, Congress provides a deduction for QTIP trust assets. QTIP
    is property in a testamentary trust created by a deceased spouse for the benefit of the
    surviving spouse. The result of the deduction is that "[t]he spouse who dies first
    3
                                                    
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    controls the final disposition of the property, while allowing the surviving spouse to use
    the property or receive the income it generates, unreduced by front-end estate
    taxation." Bracken, 175 Wn.2d at 556. Typically, terminable interests, such as life
    estates, do not qualify for the marital tax deduction.         See id. at 555.     However,
    Congress created an exception for QTIP assets. The effect of the deduction is that
    the property is ultimately taxed, but the property is not taxed when the first spouse
    creates the life estate. /d. at 556. The transfer of property is taxed when the second
    spouse dies and the ultimate beneficiaries become present interest holders. /d.
    Estate taxes are excise taxes. West     v.   Okla. Tax Comm'n, 
    334 U.S. 717
    , 727,
    
    68 S. Ct. 1223
    , 
    92 L. Ed. 1676
     (1948). Whether a tax is an excise tax or a direct tax
    is significant because the Washington State Constitution imposes a uniformity
    requirement on direct taxes, but the uniformity requirement does not apply to excise
    taxes. CaNST. art. VII,§ 1; Dean v. Lehman, 
    143 Wn.2d 12
    , 25-26, 
    18 P.3d 523
     (2001 ).
    A tax is an "excise" or "transfer" tax if the government is taxing "a particular use or
    enjoyment of property or the shifting from one to another of any power or privilege
    incidental to the ownership or enjoyment of property." Fernandez       v.   Wiener, 
    326 U.S. 340
    , 352, 
    66 S. Ct. 178
    , 
    90 L. Ed. 116
     (1945).
    The 2005 Act imposed a tax on "every transfer of property located in
    Washington" and applied prospectively to estates of decedents dying on or after May
    17, 2005. LAWS OF 2005, ch. 516, §§ 3(1 ), 20. Therefore, a transfer (upon which the
    excise tax operates) must occur on or after May 17, 2005.

    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    Estate of Bracken
    In Bracken, we held that DOR overstepped its authority by adopting regulations
    that taxed QTIP assets when the deceased spouse died before the effective date of
    the 2005 Act. Bracken, 175 Wn.2d at 554; see LAWS OF 2005, ch. 516, § 20. In
    Bracken, the deceased spouses made QTIP elections under federal law before
    Washington enacted its stand-alone estate tax and the surviving spouses died after
    the legislature passed the Act. See 175 Wn.2d at 556, 561-62. The estate in Bracken
    argued that the taxable transfer occurred when the first spouse died (before the Act
    came into effect), while DOR argued that a taxable transfer occurred when the second
    spouse died (after the Act came into effect). See id. at 561-63.
    We interpreted "transfer" narrowly and reasoned that the only "transfer"
    occurred at the husbands' deaths when they created the QTIP trusts. See id. at 554,
    563. Any transfers that occurred later upon the wives' deaths were fictional. /d. at
    554. Therefore, DOR exceeded its authority under the Act, which requires a transfer,
    by creating regulations that allowed taxation of fictional transfers. /d. According to
    our interpretation in Bracken, the "real" transfers occurred before the 2005 estate law
    was enacted. DOR could not tax these transfers because the legislature declared
    that the Act was prospective only. See LAWS OF 2005, ch. 516, § 20. The court did
    not reach alleged constitutional issues because it construed the estate tax to apply
    only to real transfers. See 175 Wn.2d at 563.

    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    The concurring/dissenting opinion disagreed with the majority's narrow
    interpretation of "transfer."   See id. at 576 (Madsen, C.J., concurring/dissenting).
    However, the concurring/dissenting opinion still agreed that the legislature did not
    intend to tax the QTIP, but for reasons differing from the majority. /d. at 594 (Madsen,
    C.J., concurring/dissenting) ("The 2006 regulations on their face and according to their
    plain language effectuate the obvious purpose of the legislature's determination to
    allow a state QTIP election: the surviving spouses' estates are not subject to state
    estate taxation on federal estate QTIP elections that did not benefit the first spouses'
    estates on any state estate tax returns by allowing a state marital deduction when the
    first spouses died."). The concurring/dissenting justices noted that the legislature
    could amend the statute if it intended a different result, so long as the amendments
    did not offend the constitution. /d. at 594-95.
    The result of the Bracken decision was that the State could not tax the QTIP
    trusts created by spouses dying before the Act was enacted because the spouse did
    not make a state QTIP election. See id. at 554.
    2013 Amendments
    In 2013, the legislature responded to Bracken by amending the Act to tax QTIP
    assets upon the death of the surviving spouse. LAWS OF 2013, 2d Spec. Sess., ch. 2,
    § 1. Disagreeing with Bracken's narrow interpretation of the term "transfer," the
    legislature noted that under the federal estate tax code "transfer" is "construed broadly
    and extends to the 'shifting from one to another of any power or privilege incidental to
    6
                                                  
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    the ownership or enjoyment of property' that occurs at death." /d. § 1(3) (quoting
    Fernandez, 326 U.S. at 352). The legislature also found that Bracken
    (a) Creates an inequity never intended by the legislature because
    unmarried individuals did not enjoy any similar opportunities to avoid or
    greatly reduce their potential Washington estate tax liability; and (b) may
    create disparate treatment between QTIP property and other property
    transferred between spouses that is eligible for the marital deduction.
    /d. § 1(4 ).   In response to its findings, the legislature broadened the meaning of
    "transfer" to its "broadest possible meaning consistent with established United States
    supreme court precedents .... " /d. § 1(5).
    The legislature intended for the amendments to "apply both prospectively and
    retroactively to all estates of decedents dying on or after May 17, 2005." /d. § 9.
    However, the amendments do "not affect any final judgment, no longer subject to
    appeal, entered by a court of competent jurisdiction before the effective date of this
    section[, June 14, 2013]." /d.§ 10.
    The amendment modified the definition of "transfer." The definition of "transfer"
    now reads, '"Transfer' means 'transfer' as used in section 2001 of the internal revenue
    code and includes any shifting upon death of the economic benefit in property or any
    power or legal privilege incidental to the ownership or enjoyment of property. ... " /d.
    § 2(12) (italics indicate added language). Section 2001 of the Internal Revenue Code
    (IRC) uses "transfer" in the following context: "A tax is hereby imposed on the transfer
    of the taxable estate of every decedent who is a citizen or resident of the United
    States." 26 U.S.C. § 2001 (a).
    7
                                                          
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    The legislature also amended the definition of the "Washington taxable estate."
    The amended definition is, in relevant part, "the federal taxable estate and includes,
    but is not limited to, the value of any property included in the gross estate under
    section 2044 of the internal revenue code, regardless of whether the decedent's
    interest in such property was acquired before May 17, 2005 . ... "            LAWS OF   2013, 2d
    Spec. Sess., ch. 2, § 2(14) (italics indicate added language). Section 2044 requires
    that QTIP assets be included in the value of the surviving spouse's gross estate. See
    26 U.S.C. § 2044(a).
    The legislature's amendments clarified the intent of the legislature to include
    QTIP trusts created before 2005 in the surviving spouse's Washington taxable estate
    (if the surviving spouse died after the Act's effective date).
    We now turn to the facts of the two cases before us.
    Estate of Hambleton
    Floyd Hambleton died on April 13, 2005, when there was no Washington estate
    tax in effect. His will left a testamentary trust for the benefit of his wife that qualified
    for the federal QTIP election. His estate made the federal QTIP election, but no such
    election existed under state law. His wife, Helen M. Hambleton, died on October 11,
    2006. Helen's 1 federal taxable estate included the value of the QTIP trust property,
    but the estate did not include the property in its Washington taxable estate. DOR
    1   For the sake of clarity, we refer to the spouses by their first names. We intend no disrespect.

    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    disallowed a $4.7 million QTIP deduction and filed findings fixing the tax due. DORis
    seeking an additional $1,184,989.16 in taxes. The estate filed objections to findings
    fixing the tax due and petitioned for declaratory and other relief. The parties agreed
    to stay the matter pending our decision in Bracken.
    Following Bracken, the estate filed a motion for summary judgment, arguing
    that the Washington taxable estate could not include the federal QTIP election. The
    trial court granted summary judgment in favor of the estate, DOR appealed, and our
    court accepted certification under RAP 4.2.
    Estate of Macbride
    Thomas Macbride died on October 20, 1999, leaving a QTIP marital deduction
    trust for the lifetime benefit of his wife, Jessie C. Macbride. His estate made a federal
    election under 26 U.S.C. § 2056(b)(7). Jessie later died on October 21, 2007. The
    estate timely deposited funds with the State prior to filing either its federal or state
    estate tax returns. The estate paid taxes on the QTIP under protest and then sought
    a refund of $643,953, the taxes paid on the QTIP assets.                  The personal
    representatives brought this action for a refund, but the superior court granted
    summary judgment to DOR.
    The estate filed a notice of appeal, seeking review of the order denying
    summary judgment in favor of petitioners, the order affirming agency action, and the
    order denying a motion for reconsideration.       After this court accepted review of
    Bracken (but before the court set a date for oral argument), DOR moved to stay

    review.    The estate opposed the motion, and the Court of Appeals commissioner
    denied the motion. In the ruling, the commissioner explained that Bracken was not
    yet set for oral argument and the parties could seek to transfer the case to the
    Washington Supreme Court after briefing was complete. Thereafter, neither party
    sought transfer. After the Bracken argument was set, the commissioner asked the
    parties to brief whether the Court of Appeals should stay review pending resolution of
    Bracken. The record contains a response only from DOR. The commissioner stayed
    the appeal until our court resolved Bracken, whereupon we granted DOR's motion to
    transfer the case to this court and consolidate it with Hambleton.
    Analvsis
    The Estates challenge the 2013 amendments on a variety of grounds. The
    constitutional arguments focus on the separation of powers doctrine, due process
    clause (U.S. CONST. amend XIV), impairment of contracts clause (U.S. Const. art. I, §
    10, cl. 2; WASH. CONST. art. I,§ 23), and article VII, section 1 of the state constitution.
    The ex post facto clauses of the state and federal constitutions apply only to penalties
    and, therefore, do not apply to taxes.    See In re Pers. Restraint of Yates, 
    180 Wn.2d 33
    , 51, 
    321 P.3d 1195
     (2014). The delegates to Washington's constitutional
    convention of 1889 could have included an ex post facto clause applicable to civil
    cases; they did not.    Hence, the Estates rely on other constitutional clauses. We
    analyze this case under principles applicable to civil cases, not criminal cases.

    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    As a general rule, our state legislature possesses plenary power to tax except
    as limited by the constitution. Be/as v. Kiga, 
    135 Wn.2d 913
    , 919-20, 
    959 P.2d 1037
    (1998). We presume that statutes are constitutional and place "the burden to show
    unconstitutionality ... on the challenger." Amunrud v. Bd. of Appeals, 
    158 Wn.2d 208
    ,
    215, 
    143 P.3d 571
     (2006).
    The arguments unrelated to the constitution include estoppel, the statute of
    limitations, and the existence of a final judgment. We review questions of law de novo,
    as well as orders granting summary judgment.       Cost Mgmt. Servs., Inc. v. City of
    Lakewood, 
    178 Wn.2d 635
    , 641, 
    310 P.3d 804
     (2013); Smith        v. Safeco Ins. Co., 
    150 Wn.2d 478
    , 483, 
    78 P.3d 1274
     (2003).
    Separation of Powers
    We hold that the legislature did not intrude upon judicial power when it
    retroactively amended the Estate and Transfer Tax Act.     The legislature was careful
    not to affect the rights of any parties to a prior judgment, reopen a case, or interfere
    with any judicial function. See Lummi Indian Nation v. State, 
    170 Wn.2d 247
    , 263,
    
    241 P.3d 1220
     (2010).
    Our system of checks and balances incorporates the important concept of the
    separation of powers. Hale   v. Wellpinit Sch. Dist. No. 49, 
    165 Wn.2d 494
    , 503, 506,

     (1987). The function of the judiciary is
    to say what the law is, whereas the legislature's function is to set policy and draft and
    enact law. Hale, 165 Wn.2d at 506. It is important to note that although the separate
    and coequal branches fill different roles, the branches "must remain partially
    intertwined to maintain an effective system of checks and balances. The art of good
    government requires cooperation and flexibility among the branches." /d. at 507.
    In Hale, the late Justice Tom Chambers wrote for a unanimous court when we
    rejected the argument that the legislature's retroactive amendment violated the
    separation of powers doctrine. /d. at 509-10. The facts grew out of McClarty v. Totem
    Electric, 
    157 Wn.2d 214
    , 
    137 P.3d 844
     (2006). In McClarty, the court interpreted the
    term "disability" in a way that limited the reach of Washington's Law Against
    Discrimination (WLAD), chapter 49.60 RCW. See Hale, 165 Wn.2d at 501. Just as
    the legislature responded to Bracken by retroactively changing the law, the legislature
    changed the definition of "disability" announced by the court in McClarty. /d. at 501;
    see LAWS OF 2007, ch. 317, § 1. The amendment applied retroactively to all causes
    of actions occurring before the McClarty opinion was filed and prospectively to all
    causes of action occurring after the legislature passed the amendment. Hale, 165
    Wn.2d at 502; LAWS OF 2007, ch. 317, § 1.

    The practical effects of the McClarty decision and the amendments on the
    parties in Hale were tangible. Hale was diagnosed with an anxiety disorder. Hale,
    165 Wn.2d at 499. After we decided McClarty, the trial judge granted summary
    judgment in favor of Hale's employer, the Wellpinit school district, because Hale's
    ailment did not qualify as a disability. See id.     Shortly thereafter, the legislature
    amended the WLAD to include a broad definition of "disability." /d. at 500. Hale filed
    a motion for reconsideration, which the trial court denied, reasoning that applying the
    amendment retroactively would violate the separation of powers doctrine. /d. The
    trial judge then certified the issue to our court. /d. We unanimously held that applying
    the amendment retroactively to Hale did not intrude upon judicial powers. /d. at 510.
    Justice Chambers explained that although it is the court's obligation to
    determine and carry out the intent of the legislature, the legislature is occasionally
    disappointed with the court's interpretation. /d. at 509. By amending the statute, "the
    legislature acted wholly within its sphere of authority to make policy, to pass laws, and
    to amend laws already in effect." /d. He noted, "The legislature was careful not to
    reverse our decision in McClarty nor did the legislature interfere with any judicial
    function." /d. at 510. He praised the cooperation between the legislature and the
    court, stating:
    [The court's interpretation of the statute and the legislature's responsive
    amendment] should serve as a model of how two separate and
    independent branches of government can work together in harmony and
    in the spirit of reciprocal deference to the other's important role and
    function in the art of governing.

    /d.
    The court held similarly in Lummi Indian Nation, 170 Wn.2d at 262-63. The
    facts in Lummi Indian Nation arose out of Department of Ecology v. Theodoratus, 
    135 Wn.2d 582
    , 
    957 P.2d 1241
     (1998), and the legislature's subsequent amendment to
    municipal water law. See Lummi Indian Nation, 170 Wn.2d at 251. In Theodoratus,
    we held that under a then-existing statute, private water rights not did vest until the
    water was put to an "actual beneficial use." /d. at 255.      This was a departure from
    the Department of Ecology's practice of issuing permits and certificates based upon a
    showing of need and capacity. /d. We cautioned that the opinion did not consider
    municipal water rights, which were treated differently under the law. /d. at 251, 255.
    The legislature responded to our opinion by amending the municipal water law to
    "explicitly define certain nongovernmental water suppliers as municipal and to make
    that definition retroactive."   /d. at 251.
    The issue before the court in Lummi Indian Nation was whether the amendment
    violated the separation of powers doctrine when its retroactive application narrowed
    the applicability of our holding. /d. at 260. Writing again for a unanimous court, Justice
    Chambers concluded that the retroactive amendments did not offend the separation
    of powers doctrine. /d. at 262-63.      He relied heavily on Hale. See id. at 261-63.
    In Hale, we said that in order to decide whether the retroactive
    application of a statute violates separation of powers we must determine
    "whether the activity of one branch threatens the independence or
    integrity or invades the prerogatives of another." . . . Retroactive
    legislation that interferes with vested rights established by judicial rulings
    interferes with a judicial function or results in manifest injustice or
    14

    consolidated with
    In re Estate of Macbride, No. 89500-7
    threatens the independence, integrity, or prerogatives of the judicial
    branch may violate separation of powers.
    However, in Hale, we also firmly rejected the contention that just
    because an appellate court's statutory interpretation relates back to the
    time the statute was originally adopted, any retroactive amendment of
    that statute violates separation of powers. Indeed, it is wholly within the
    sphere of authority of the legislative branch to make policy, to pass laws,
    and to amend laws already in effect.
    /d. at 262 (citations omitted) (internal quotation marks omitted) (quoting Hale, 165
    Wn.2d at 507). Applying these principles, the unanimous court found no separation
    of powers violation. !d. at 263. "The legislature made no attempt to apply the law to
    an existing set of facts, affect the rights of parties to the court's judgment, or interfere
    with any judicial function."      /d.   Its actions did not threaten the independence or
    integrity of the judiciary. /d.
    We apply the principles and reasoning announced in Hale to the facts before
    us and hold that the retroactive amendment does not offend the separation of powers
    doctrine. The sequence of events here is very similar to those in Hale. In Hale, the
    employer's alleged discriminatory conduct occurred in 2002-03. Hale, 165 Wn.2d at
    499. In 2006, Hale filed suit against the employer. /d. On July 6, 2006, we issued
    the McClarty decision, in which we interpreted "disability" narrowly. See McClarty,
    157 Wn.2d at 228. The trial judge granted partial summary judgment against Hale
    because Hale was not disabled under the definition we adopted in McClarty. Hale,
    165 Wn.2d at 499. The following month, the legislature rejected our interpretation of
    "disability," statutorily defined the term, and applied the amendment retroactively
    15
                                                 
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    (except for cases occurring between the dates when McClarty was announced and
    the amendment was enacted). See id. at 500.
    Here, the estate of Hambleton objected to DOR's disallowing the QTIP
    deduction and petitioned for declaratory relief. After we issued Bracken, the trial court
    granted the estate summary judgment because there was no taxable transfer under
    our narrow interpretation of "transfer." The legislature then amended the definition to
    include QTIP transfers and applied the amendment retroactively. The sequence of
    events is identical to those in Hale. 2
    The court unequivocally allowed a retroactive amendment to change our
    interpretation of a statute in Hale. We will not overrule the rules announced in Hale
    and Lummi Indian Nation. Therefore, we hold the same today. The 2013 amendment
    does not offend the separation of powers doctrine. The legislature was careful to draft
    the law so that it "does not affect any final judgment, no longer subject to appeal,
    entered by a court of competent jurisdiction before the effective date of this section[,
    June 14, 2013]." LAWS OF 2013, 2d Spec. Sess., ch. 2, § 10. Like in Hale and Lummi
    Indian Nation, the legislature was threatening neither the independence nor the
    2The sequence of events is slightly different in Macbride, but this does not change our
    analysis. The trial court granted DOR summary judgment well before the Bracken opinion
    was filed. The case was pending before the Court of Appeals when Bracken became law.
    And, the case was still pending when the legislature enacted the 2013 amendments. As in
    Hale, this case was pending before the courts when a decision by our court was released.
    The legislature retroactively changed the law. And, we apply the change in law to cases
    pending in the courts.

    It is additionally important to note that the legislature is not prohibited from
    passing amendments that directly impact cases pending in our court system. 3 Wash.

    ("Nor is the legislature prohibited from 'pass[ing] a law that directly impacts a case
    pending in Washington courts.' 'Litigation often brings to light latent ambiguities or
    unanswered questions that might not otherwise be apparent.' The legislature violates
    separation of powers principles by prescribing new rules to be applied to pending
    litigation only when doing so infringes on a judicial function by 'imped[ing] upon the
    court's right and duty to apply new law to the facts of this case,' 'dictat[ing] how the
    court should decide a factual issue,' or 'affect[ing] a final judgment.'" (alterations in

    When a legislature makes clear that an act is intended to apply retroactively, "an
    appellate court must apply that law in reviewing judgments still on appeal that were
    rendered before the law was enacted, and must alter the outcome accordingly." Plaut
    3 The Estates are really arguing this appeal as a matter of fairness. None of their
    constitutional arguments dictate that they get the relief they seek. The decision to
    retroactively amend the statute was a policy decision, properly in the sphere of the legislature.

    In Plaut, the Court reasoned:
    [The judiciary is a] department composed of "inferior Courts" and "one
    supreme Court." Within that hierarchy, the decision of an inferior court
    is not (unless the time for appeal has expired) the final word of the
    department as a whole. It is the obligation of the last court in the
    hierarchy that rules on the case to give effect to Congress's latest
    enactment, even when that has the effect of overturning the judgment of
    an inferior court, since each court at every level, must "decide according
    to existing laws."

    2 L. Ed. 49

    The legislature did not violate the separation of powers doctrine when it passed
    the retroactive amendment to the Act.
    Due Process
    Applying a rational basis standard, the 2013 amendment's retroactive
    application does not violate due process of law. See United States v. Carlton,

    114 S. Ct. 2018
    , 
    129 L. Ed. 2d 22
     (1994 ). The legislature has a
    legitimate purpose for the retroactive amendment, and the period of retroactivity is
    rationally related to that purpose. /d.

    the 2013 amendment:
    The due process standard to be applied to tax statutes with retroactive
    effect ... is the same as that generally applicable to retroactive economic
    legislation:
    "Provided that the retroactive application of a statute is supported by
    a legitimate legislative purpose furthered by rational means,
    judgments about the wisdom of such legislation remain within the
    exclusive province of the legislative and executive branches ....
    "To be sure, ... retroactive legislation does have to meet a burden
    not faced by legislation that has only future effects .... The retroactive
    aspects of legislation, as well as the prospective aspects, must meet
    the test of due process, and the justifications for the latter may not
    suffice for the former .... But that burden is met simply by showing
    that the retroactive application of the legislation is itself justified by a
    rational legislative purpose."

    proceeds of 'any sale of employer securities by the executor of an estate' to 'an
    employee stock ownership plan."' /d. at 28 (quoting former 26 U.S.C. § 2057(b) (1982
    ed. & Supp. IV)). In order to receive the deduction, the sale of securities had to take
    place before an estate filed its tax return. /d. The estate in Carlton bought and sold
    the securities for the purpose of taking advantage of the § 2057 deduction. /d. The
    transaction reduced the taxable estate by $2,501,161. /d. One week after the estate
    took advantage of the deduction, the Internal Revenue Service (IRS) announced that
    it would treat the deductions as available only to "estates of decedents who owned
    the securities in question immediately before death." /d. at 29. Almost a year later,
    Congress amended the statute to conform to the IRS' policy. The amendment was to
    be applied retroactively, "as if it had been contained in the statute as originally
    enacted" a year prior. /d. The IRS disallowed the estate's deduction, and the estate
    in Carlton argued that this violated its due process rights. /d. The Court found no due
    process violation. /d. at 32-33.
    First, there was a legitimate purpose. Congress enacted the amendment to
    correct a mistake that "would have created a significant and unanticipated revenue
    loss." /d. at 32. This purpose was neither arbitrary nor illegitimate. /d. Second, the
    means were rationally related to the purpose. /d. at 32-33. The period of retroactivity
    extended slightly longer than one year. /d. at 33. The amendments were introduced
    in Congress shortly after the problem was discovered, and it took time to pass national
    legislation. See id. at 32-33. In reaching its conclusion in Carlton, the Court noted

    that it "repeatedly has upheld retroactive tax legislation against a due process
    challenge." /d. at 30.
    Courts have upheld retroactive periods that are short and limited to that
    required by the practicalities of producing legislation and have upheld longer
    retroactive periods as well. See United States v. Oarusmont,

    221 Ariz. 123
    , 125-29, 
    211 P.3d 1
     (Ct. App. 2008).
    Our court found that a retroactive period spanning more than seven years did not
    violate the due process clause in WR. Grace. 137 Wn.2d at 586-87.
    The facts in WR. Grace involved the legislature's amending an unconstitutional
    business and occupation tax. The amendment limited taxpayer relief to a tax credit
    and applied retroactively. /d. at 586. A challenger sought relief from taxes it paid
    seven years before the amendment was enacted.            See id. at 587. We found that
    there was a "rational legislative purpose" and the "retroactive application of the ...
    remedial legislation [did] not offend constitutional principles." /d. at 603.
    Similarly, an amendment to the Railroad Retirement Tax Act, 26 U.S.C. § 3231,
    which applied retroactively for seven years, passed constitutional muster because it
    served a legitimate purpose (i.e., preventing a loss of government revenue and
    protecting employees who relied on receiving higher retirement benefits) and the
    period of retroactivity bore "a rational relation to [the] underlying legislative purpose."

    76 F. 3d at 993-94
    . "A shorter period of retroactivity would have
    been arbitrary and irrational." /d. at 994. 4
    Here, the retroactive application of the 2013 amendments meets the rational
    basis standard. See Carlton, 
    512 U.S. at 30-31
    . As stated in§ 1 of the amendment,
    the purpose is to "restore parity between married couples and unmarried individuals
    [by not allowing married individuals to avoid or greatly reduce their potential
    Washington estate tax liability], restore parity between QTIP property and other
    property eligible for the marital deduction, and prevent the adverse fiscal impacts of
    the Bracken decision .... "        LAWS OF   2013, 2d Sp. Sess., ch. 2, § 1(5). Like the
    legitimate purpose in Carlton, the purpose of the 2013 amendment is largely
    economic. Carlton, 
    512 U.S. at 32
    . According to the DOR fiscal note, the legislation
    was anticipated to
    increase revenues to the education legacy trust account by an estimated
    $118.4 million in Fiscal Year 2014. The estimated revenue increase
    reflects the retroactive clarifications of the definitions of "transfer" and
    "Washington taxable estate" to conform to the Department's
    interpretation, thereby eliminating any refund claims resulting from the
    recent court decision, other than for the Estate of Bracken. It also reflects
    other changes made to existing estate tax law.
    4 The Estates' briefs suggest that Carlton creates a threshold on the period of retroactivity.
    Our court has allowed periods of retroactivity extending beyond one year, as have other
    jurisdictions. WR. Grace, 137 Wn.2d at 586-87; Mont. Rail Link, Inc.,

    512 U.S. at 32
    .
    The period of retroactivity is also rationally related to preventing the fiscal
    shortfall. It provides the necessary funds, and the length of retroactivity is directly
    linked with the purpose of the amendment, which is to remedy the effects of Bracken.
    The amendment applies to all estates since our State enacted the Act. This period of
    retroactivity is not arbitrary.   However, any period less than eight years would be
    arbitrary. It would allow some estates to escape the tax while similarly situated estates
    would be subject to it. Additionally, the eight-year period of retroactivity is not far
    outside other retroactive periods that courts have accepted. See WR. Grace, 137
    Wn.2d at 586-87; Mont. Rail Link, Inc., 
    76 F.3d 993
    -94; Enter. Leasing Co., 
    211 P.3d 1
    . Therefore, the retroactive period meets the due process clause's rational basis
    test.
    The Estates make two failing arguments regarding the due process clause.
    First, the Estates argue that the 2013 amendments impose a wholly new tax, making
    the Carlton standard inapplicable. The Ninth Circuit rejected this argument in Quarty
    v. United States, 
    170 F. 3d 961
    , 966-67 (9th Cir. 1999). The parties were attempting
    avoid the application of Carlton and, instead, invoke precedent from the 1920s. /d. at
    966. The 1920s cases considered retroactive application of the first gift tax, which
    violated due process. /d. The Ninth Circuit quoted Carlton:

    "Those cases were decided during an era characterized by exacting
    review of economic legislation under an approach that 'has long since
    been discarded.' To the extent that their authority survives, they do not
    control here. Blodgett and Untermyer, which involved the Nation's first
    gift tax, essentially have been limited to situations involving 'the creation
    of a wholly new tax,' and their 'authority is of limited value in assessing
    the constitutionality of subsequent amendments that bring about certain
    changes in the operation of the tax laws."'

    90 L. Ed. 2d 538
     (1986))). The
    court concluded, "[A] new tax is imposed only when the taxpayer has 'no reason to
    suppose that any transactions of the sort will be taxed at all."' /d. at 967 (quoting
    Darusmont, 
    449 U.S. at 298, 300
    ).
    The 2013 amendments did not create a wholly new tax. Washington has long
    received revenue from estate taxes, and the taxpayers had "reason to suppose" that
    the state would tax shifting interests in assets upon death.           See 
    id.
        Therefore,
    Carlton's rational basis test applies. See 
    id.
    The Estates' second unsuccessful argument is that applying the amendments
    retroactively is unconstitutional because it impairs a vested right acquired under
    existing law. Appellant's Suppl. Br. at 27 ("the existing law here being, in effect, no
    estate tax at all, or rather the 'pickup' tax Washington instituted in 1981 "). "A statute
    may not be applied retroactively to infringe a vested right." In re Pers. Restraint of
    Carrier, 
    173 Wn.2d 791
    , 810, 
    272 P.3d 209
     (2012). We recently stated:

    consolidated with
    In re Estate of Macbride, No. 89500-7
    This notion finds root in the due process clauses of the Fifth and
    Fourteenth Amendments. While due process generally does not prevent
    new laws from going into effect, it does prohibit changes to the law that
    retroactively affect rights which vested under the prior law. We have said
    that
    [a] vested right, entitled to protection from legislation, must be
    something more than a mere expectation based upon an anticipated
    continuance of the existing law; it must have become a title, legal or
    equitable, to the present or future enjoyment of property, a demand,
    or a legal exemption from a demand by another.
    /d. at 811 (alteration in original) (citations omitted) (quoting Godfrey v. State, 
    84 Wn.2d 959
    , 963, 
    530 P.2d 630
     (1975)). For example, we declined to apply an amendment
    retroactively when the legislature was silent as to retroactivity and a party had a vested
    interest. In re F.D. Processing, Inc., 
    119 Wn.2d 452
    ,460,463,
    832 P.2d 1303
     (1992).
    Here, DOR correctly notes that the Estates do not explain what vested right the
    remainder beneficiaries held in the QTIP that was impacted by the amendment. The
    remaindermen had vested rights in the trust property upon the death of the first
    spouse.    This interest became a vested present interest upon the death of the
    surviving spouse, and the legislature is taxing the shift in interest. The estate tax does
    not deprive the remaindermen of their interest in the property or change the nature of
    their interest. It simply taxes the transfer of assets.
    On a related note, in Carlton, the Supreme Court stated,
    Tax legislation is not a promise, and a tax payer has no vested right in
    the Internal Revenue Code. Justice Stone explained in Welch v. Henry,
    305 U.S. [134, 146-47, 
    59 S. Ct. 121
    , 
    83 L. Ed. 87
     (1938):]

    which he assumes by contract. It is but a way of apportioning the

    cost of government among those who in some measure are privileged
    to enjoy its benefits and must bear its burdens. Since no citizen
    enjoys immunity from that burden, its retroactive imposition does not
    necessarily infringe due process .... "
    Carlton, 
    512 U.S. at 33
     (alteration in original). Similarly, the Estates here do not have
    a vested right in Washington's pre-2005 pickup tax scheme.
    There is no due process violation because the 2013 amendments serve a
    legitimate purpose and the period of retroactivity is rationally related to that purpose.
    Impairment of Contract
    The 2013 amendments do not violate the impairment of contracts clause
    because the amendments are not a substantial impairment to a contract and the
    legislative amendment was reasonably necessary.
    Both the federal constitution and Washington State Constitution protect citizens
    from state laws that impair the obligation of contracts. CONST. art. I, § 23; U.S. CONST.
    art. I, § 10, cl. 1; see Wash. Fed'n of State Emps. v. State, 
    101 Wn.2d 536

     (1984) ("[Const. art. I, § 23] is substantially the same as U.S. Const. art. 1,
    § 10 and is to be given the same effect."). Like many other constitutional rights, the
    clause's protections are not absolute; "its prohibition must be accommodated to the
    inherent police power of the State 'to safeguard the vital interests of its people."'

    As a threshold matter, we inquire into "whether the state law has, in fact,
    operated as a substantial impairment of a contractual relationship." /d. at 411 (quoting
    Allied Structural Steel Co. v. Spannaus, 
    438 U.S. 234
    , 244, 
    98 S. Ct. 2716
    , 
    57 L. Ed. 2d 727
     (1978)). "The impaired relationship must be a 'contract' in the usual sense of
    the word 'signifying an agreement of two or more minds, upon sufficient consideration,
    to do or not to do certain acts."' Haberman, 109 Wn.2d at 145 (quoting Crane v. Hahlo,

    , 146, 
    42 S. Ct. 214
    , 
    66 L. Ed. 514
     (1922)). However, in 1931, the United
    States Supreme Court applied the contracts clause to a trust deed. Coolidge v. Long,
    
    282 U.S. 582
    , 595, 
    51 S. Ct. 306
    , 
    75 L. Ed. 562
     (1931 ). "A contract is impaired by a
    statute which alters its terms, imposes new conditions or lessens its value." Caritas

    123 Wn.2d 391
    , 404, 
    869 P.2d 28
     (1994 ).
    We look for a substantial impairment. Margo/a Assocs. v. City of Seattle, 
    121 Wn.2d 625
    , 653, 
    854 P.2d 23
     (1993). An impairment may be substantial if a party relied on
    the supplanted clause. Caritas, 
    123 Wn.2d at 405
    . However, "a party who enters into
    a contract regarding an activity 'already regulated in the particular [way] to which he
    now objects' is deemed to have contracted 'subject to further legislation upon the
    same topic'." Margo/a Assocs., 
    121 Wn.2d at 653
     (quoting Veix v. Sixth Ward Bldg. &
    Loan Ass'n,

    , 38, 60 S .Ct. 792, 
    84 L. Ed. 1061
     (1940)).
    If the threshold is met and the contract is between private parties, we determine
    whether the enactment was reasonably necessary. Carlstrom v. State, 
    103 Wn.2d 391
    , 394, 
    694 P.2d 1
     (1985). "The contracts clause does not prohibit the states from

    In re Estate of Macbride, No. 89500-7
    repealing or amending statutes generally, or from enacting legislation with retroactive
    effects." Haberman, 109 Wn.2d at 145.
    Here, the threshold inquiry is not met and the amendments were reasonably
    necessary. There was no substantial impairment of the trust because it was reasonable
    for the Estates to expect that the estate tax law would change. See Coolidge, 
    282 U.S. at 595
    . Additionally, the 2013 amendments meet the "reasonably necessary" standard
    for contracts where the State is not a party. The purpose of the amendments is to provide
    revenue to fund education. See    LAWS OF   2013, 2d Spec. Sess., ch. 2, § 1(1). "'[T]he
    State ... has an affirmative paramount duty to make ample provision for funding the
    'basic education' .... " McCleary   v. State, 
    173 Wn.2d 477
    , 517,

    (second alteration in original) (quoting Seattle Sch. Dist. No. 1 v. State, 
    90 Wn.2d 476
    ,
    520, 
    585 P.2d 71
     (1978)). Imposing a tax on the Estates prevented the fiscal shortfall
    created by Bracken. Therefore, the 2013 amendments do not unconstitutionally impair
    contracts.
    Article VII, Section 1
    We hold that the amendments do not violate article VII, section 1 of the
    Washington State Constitution. Article VII, section 1 provides, "All taxes shall be
    uniform upon the same class of property within the territorial limits of the authority
    levying the tax and shall be levied and collected for public purposes only."        This
    uniformity requirement applies only to property tax and not excise tax. Dean, 143
    Wn.2d at 25-26 ("Excise taxes also fall beyond the breadth of the uniformity
    28
                                                   
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    requirement."). Because the estate tax is an excise tax, the 2013 amendments do not
    violate article VII, section 1 of the Washington Constitution.
    A tax is an "excise" or "transfer" tax if the government is taxing "a particular use
    or enjoyment of property or the shifting from one to another of any power or privilege
    incidental to the ownership or enjoyment of property." Fernandez, 326 U.S. at 352. An
    estate tax is an excise tax because the tax is "not levied on the property of which an
    estate is composed. Rather it is imposed upon the shifting of economic benefits and
    the privilege of transmitting or receiving such benefits." West, 
    334 U.S. at 727
    .
    Transfers are broadly construed at death under federal estate tax law-the
    system upon which the Act is based. For example, the United States Supreme Court
    stated:
    [T]he [federal] estate tax as originally devised and constitutionally
    supported was a tax upon transfers. But the power of Congress to
    impose death taxes is not limited to the taxation of transfers at death. It
    extends to the creation, exercise, acquisition, or relinquishment of any
    power or legal privilege which is incident to the ownership of property,
    and when any of these is occasioned by death, it may as readily be the
    subject of the federal tax as the transfer of the property at death.
    Fernandez, 326 U.S. at 352 (citations omitted). The First Circuit Court of Appeals has
    stated that the estate tax is not "in a strict sense a tax upon a 'transfer' of the property
    by the death of the decedent. It is an excise tax upon the happening of an event,
    namely, death, where the death brings about certain described changes in legal
    relationships affecting property." Chickering v. Comm'r of Internal Revenue, 
    118 F.2d 254
    , 257-58 (1st Cir. 1941 ).
    29
                                                          
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    Following these general principles, taxing QTIP assets upon the death of a
    surviving spouse qualifies as an excise tax. The surviving spouse had the economic
    benefit of using the income from QTIP assets during his or her life. And, upon the
    surviving spouse's death, the remainder beneficiaries of the trust gained a present
    interest in the assets and income. The death of the surviving spouse brought about
    "changes in legal relationships affecting property."          /d. Therefore, the Estate and
    Transfer Tax Act is an excise tax and not subject to article VII, section 1.
    Equitable & Collateral Estoppel
    DOR is not equitably estopped from applying the 2013 amendments to the
    estate of Macbride. 5 The elements of equitable estoppel are:
    (1) a party's admission, statement or act inconsistent with its later claim;
    (2) action by another party in reliance on the first party's act, statement
    or admission; and (3) injury that would result to the relying party from
    allowing the first party to contradict or repudiate the prior act, statement
    or admission.
    5 Neither of the Estates raises the issue of judicial estoppel. "'Judicial estoppel is an equitable
    doctrine that precludes a party from asserting one position in a court proceeding and later
    seeking an advantage by taking a clearly inconsistent position."' Anfinson v. FedEx Ground
    Package Sys., Inc., 
    174 Wn.2d 851
    , 861, 
    281 P.3d 289
     (2012) (internal quotation marks
    omitted) (quoting Arkison v. Ethan Allen, Inc., 
    160 Wn.2d 535
    , 538, 
    160 P.3d 13
     (2007)).
    Three factors guide judicial estoppel: "(1) whether 'a party's later position' is 'clearly
    inconsistent with its earlier position'; (2) whether 'judicial acceptance of an inconsistent
    position in a later proceeding would create the perception that either the first or the second
    court was misled'; and (3) 'whether the party seeking to assert an inconsistent position would
    derive an unfair advantage or impose an unfair detriment on the opposing party if not
    estopped."' Arkison, 160 Wn.2d at 538-39 (internal quotation marks omitted) (quoting New
    Hampshire v. Maine, 
    532 U.S. 742
    , 750-51, 
    121 S. Ct. 1808
    , 
    149 L. Ed. 2d 968
     (2001 )).
    Judicial estoppel is not applicable. The parties have not taken inconsistent positions, nor
    have they misled the court. It was the legislature that changed the law that applies to the
    cases.

    122 Wn.2d 738
    , 743, 
    863 P.2d 535
    ( 1993). Assertions of equitable estoppel against the government are not favored;
    parties must demonstrate that equitable estoppel is necessary to prevent a manifest
    injustice and that the exercise of governmental functions will not be impaired as a
    result of the estoppel.   /d.   Generally, we "should be most reluctant to find the
    government equitably estopped when public revenues are involved." /d. at 744.
    The estate of Macbride bases its estoppel argument on the fact that had it
    transferred its appeal to our court alongside Bracken, the 2013 amendment would not
    apply to it. However, the estate fails to prove the second element with clear, cogent,
    and convincing evidence, in that the estate failed to prove reliance on DOR's
    statements. See City of Seattle v. St. John, 
    166 Wn.2d 941
    , 948-49, 
    215 P.3d 194
    (2009).
    DOR moved to stay proceedings pending our decision in Bracken. It reasoned
    that the current case and Bracken involved the same legal issues and that our decision
    in Bracken would likely resolve the estate of Macbride's appeal and make any further
    proceedings moot. Even if the motion is a statement or assertion, the estate did not
    rely upon it. Instead, the estate filed a response that opposed DOR's motion to stay.
    Given these facts, equitable estoppel does not apply.
    Additionally, collateral estoppel does not prevent DOR from relitigating issues.
    Before a court will invoke collateral estoppel,
    the party asserting the doctrine must prove: (1) the issue decided in the
    prior adjudication is identical with the one presented in the second action;
    31
                                                  
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    (2) the prior adjudication must have ended in a final judgment on the
    merits; (3) the party against whom the plea is asserted was a party or in
    privity with the party to the prior adjudication; and (4) application of the
    doctrine does not work an injustice.
    Nielson v. Spanaway Gen. Med. Clinic, Inc., 
    135 Wn.2d 255
    , 262-63, 
    956 P.2d 312
    (1998). However, an issue may not be precluded if "a new determination is warranted
    in order to take account of an intervening change in the applicable legal context or
    otherwise to avoid inequitable administration of the laws." RESTATEMENT (SECOND) OF
    JUDGMENTS § 28(2)(b) (1982).         Here, the applicable law has been amended.
    Therefore, review is warranted to take account of this change. See id.
    Statute of Limitations
    The statute of limitations does not prevent the 2013 amendments from applying
    to the estate of Hambleton.        Under RCW 83.1 00.095(3), "[n]o assessment or
    correction of an assessment for additional taxes ... may be made by the department
    more than four years after the close of the calendar year in which a Washington return
    is due ...." DOR issued its assessment of taxes due on November 18, 2008, only
    two years after Helen Hambleton passed away. In the assessment, the amount owing
    was "attributable to the [e]state's exclusion of . . . '§2044 property' from the
    Washington taxable estate." Clerk's Papers at 17-18. The estate filed its Washington
    State estate tax return on January 11, 2008. Therefore, DOR issued its assessment
    well within the four year statute of limitations. See RCW 83.1 00.095(3). The estate
    offers no support as to why a new or corrected assessment is needed.                  The
    assessment has always included QTIP trust property. The estate has had notice of
    32
                                                 
    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    the amount due since 2008. Therefore, the 2013 amendments are not barred by the
    statute of limitations. See RCW 83.1 00.095(3).
    Final Judgment
    The estate of Hambleton argues that the trial court's ruling was final at the time
    the legislature enacted the 2013 amendment, so the amendment should not apply to
    it. See LAWS OF 2013, 2d Spec. Sess., ch. 2, § 10 ("[The] act does not affect any final
    judgment, no longer subject to appeal, entered by a court of competent jurisdiction
    before the effective date of this section."). We disagree. The estate arrives at this
    conclusion by arguing that DOR had no basis in law upon which to appeal the order
    granting summary judgment because DOR appealed the order before the
    amendments were enacted. This reasoning is unpersuasive.
    Generally, "[w]hen a new law makes clear that it is retroactive, an appellate
    court must apply that law in reviewing judgments still on appeal that were rendered
    before the law was enacted, and must alter the outcome accordingly." Plaut, 
    514 U.S. at 226
    .    Therefore, despite the existence of a "final" trial court ruling, retroactive
    amendments may apply to cases pending on appeal.
    A party may appeal final trial court judgments. RAP 2.2(a)(1 ). However, parties
    may not frivolously appeal or appeal simply for purposes of delay.         RAP 18.9(c).
    Appellate courts will, on motion from the opposing party, dismiss frivolous appeals and
    appeals brought for purposes of delay. RAP 18.9(c).

    In re Estate of Hambleton, No. 89419-1
    consolidated with
    In re Estate of Macbride, No. 89500-7
    Here, the trial court entered its order granting summary judgment on April 19,
    2013 and DOR filed a notice of appeal on May 16, 2013. The estate of Hambleton
    did not move under RAP 18.9(c) to dismiss the appeal, and the appeal was still
    pending when the legislature enacted the 2013 amendment. Therefore, the retroactive
    amendment applies to the case.
    Conclusion
    No barriers prohibit the retroactive application of the 2013 amendment to the
    Estates of Hambleton and Macbride. No genuine issues of material fact exist in the
    cases, and judgment may be entered as a matter of law.
    We reverse the order granting summary judgment to the estate of Hambleton,
    and remand for the entry of judgment in accordance with this opinion. We affirm the
    denial of summary judgment to the estate of Macbride and affirm the order affirming
    agency action and granting judgment as a matter of law to DOR.
