Findings—Intent—2003 c 3: "The legislature finds that the 1975 legislature clearly and unambiguously stated that any felony, including assault, can be a predicate offense for felony murder. The intent was evident: Punish, under the applicable murder statutes, those who commit a homicide in the course and in furtherance of a felony. This legislature reaffirms that original intent and further intends to honor and reinforce the court's decisions over the past twenty-eight years interpreting "in furtherance of" as requiring the death to be sufficiently close in time and proximity to the predicate felony. The legislature does not agree with or accept the court's findings of legislative intent in State v. Andress, Docket No. 71170-4 (October 24, 2002), and reasserts that assault has always been and still remains a predicate offense for felony murder in the second degree.

To prevent a miscarriage of the legislature's original intent, the legislature finds in light of State v. Andress, Docket No. 71170-4 (October 24, 2002), that it is necessary to amend RCW 9A.32.050. This amendment is intended to be curative in nature. The legislature urges the supreme court to apply this interpretation retroactively to July 1, 1976." [ 2003 c 3 s 1.]

Effective date—2003 c 3: "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 [February 12, 2003]." [ 2003 c 3 s 3.]

Effective date—Severability—1975-'76 2nd ex.s. c 38: See notes following RCW 9A.08.020.
