Findings—Intent—2013 2nd sp.s. c 2: "(1) In 2005, to address an unexpected significant loss of tax revenue resulting from the Estate of Hemphill decision and to provide additional funding for public education, the legislature enacted a stand-alone estate and transfer tax, effective May 17, 2005. The stand-alone estate and transfer tax applies to the transfer of property at death. By defining the term "transfer" to mean a "transfer as used in section 2001 of the internal revenue code," the legislature clearly expressed its intent that a "transfer" for purposes of determining the federal taxable estate is also a "transfer" for purposes of determining the Washington taxable estate.

(2) In In re Estate of Bracken, Docket No. 84114-4, the Washington supreme court narrowly construed the term "transfer" as defined in the Washington estate tax code.

(3) The legislature finds that it is well established that the term "transfer" as used in the federal estate tax code is construed broadly and extends to the "shifting from one to another of any power or privilege incidental to the ownership or enjoyment of property" that occurs at death. Fernandez v. Wiener, 326 U.S. 340, 352 (1945).

(4) The legislature further finds that: The Bracken decision held certain qualified terminable interest property (QTIP) of married couples was transferred without incurring Washington state estate tax liability, which: (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.

(5) Therefore, the legislature finds that it is necessary to reinstate the legislature's intended meaning when it enacted the estate tax, restore parity between married couples and unmarried individuals, restore parity between QTIP property and other property eligible for the marital deduction, and prevent the adverse fiscal impacts of the Bracken decision by reaffirming its intent that the term "transfer" as used in the Washington estate and transfer tax is to be given its broadest possible meaning consistent with established United States supreme court precedents, subject only to the limits and exceptions expressly provided by the legislature.

(6) As curative, clarifying, and remedial, the legislature intends for this act to apply both prospectively and retroactively to estates of decedents dying on or after May 17, 2005." [ 2013 2nd sp.s. c 2 s 1.]

Final judgment—Affect—2013 2nd sp.s. c 2: "This act does not affect any final judgment, no longer subject to appeal, entered by a court of competent jurisdiction before June 14, 2013." [ 2013 2nd sp.s. c 2 s 10.]

Effective dates—2013 2nd sp.s. c 2: "This act is necessary for the immediate preservation of the public peace, health, or safety, or support of the state government and its existing public institutions, and takes effect immediately [June 14, 2013], except for sections 3, 4, and 6 of this act which take effect January 1, 2014."
