What is the test for interpretation of a statute?

"Where, as here, the issue presented is one of statutory construction, our fundamental task is 'to ascertain the intent of the lawmakers so as to effectuate the purpose of the statute.' [Citations.] We begin by examining the statutory language because it generally is the most reliable indicator of legislative intent. [Citation.] We give the language its usual and ordinary meaning, and '[i]f there is no ambiguity, then we presume the lawmakers meant what they said, and the plain meaning of the language governs.' [Citation.] If, however, the statutory language is ambiguous, 'we may resort to extrinsic sources, including the ostensible objects to be achieved and the legislative history.' [Citation.] Ultimately we choose the construction that comports most closely with the apparent intent of the lawmakers, with a view to promoting rather than defeating the general purpose of the statute. [Citations.] Any interpretation that would lead to absurd consequences is to be avoided. [Citation.]" (Allen v. Sully-Miller Contracting Co. (2002) 28 Cal.4th 222, 227.)
