of the SRA, the Legislature would, sub silentio, without debate, without announcement, and without even separately articulating an exception to a specific general rule, convey authority to the courts to calculate offender scores under subsection (6) without statutory constraints of any sort.
In short, the majority’s reading creates unlikely and untenable results. To determine the correct reading, resort to statutory construction is necessary.12
Statutory Construction Analysis
1. Principles of Statutory Construction
Statutory interpretation discerns the intent of the Legislature and furthers the legislative purpose in enacting the statute. State v. McGee, 122 Wn.2d 783, 864 P.2d 912 (1993); State v. Rinkes, 49 Wn.2d 664, 306 P.2d 205 (1957). In ascertaining legislative intent, we must look to the sequence of all statutes relating to the same subject matter. Ravsten v. Department of Labor & Indus., 108 Wn.2d 143, 150, 736 P.2d 265 (1987). We presume the Legislature is aware of its prior enactments and judicial construction of them. Chandler v. Otto, 103 Wn.2d 268, 274, 693 P.2d 71 (1984). We also presume that the Legislature does not engage in meaningless or unnecessary acts. State v. Wanrow, 88 Wn.2d 221, 228, 559 P.2d 548 (1977). Thus, when the Legislature amends an unambiguous law, we presume that the Legislature intended to change the law. State v. Standifer, 110 Wn.2d 90, 94, 750 P.2d 258 (1988).
Ultimately, this court must look to the purpose or policy goals of the Legislature to effectuate its intent and to avoid absurd results. State v. McDougal, 120 Wn.2d 334, 350,

The majority asserts that its reading of the second sentence of subsection (6)(a) is the only possible interpretation, and declines to employ the customary tools of statutory construction: "We find it unnecessary to engage in such statutory construction where, as here, the language of a statute is not ambiguous”. Majority, at 288. I believe the majority’s reading is incorrect, based on the legislative history of the statute, the policy adopted by the Legislature, and the practical consequences of the majority’s interpretation.
