As used in this chapter, "expiration date" means the earliest of:

(1) The effective date that federal medicaid matching funds for the purposes specified in *section 7 of this act become unavailable or are substantially reduced, as such date is certified by the secretary of social and health services;

(2) The effective date that federal medicaid matching funds for the purposes specified in *section 7 of this act become unavailable or are substantially reduced, as determined by a permanent injunction, court order, or final court decision; or

(3) The effective date of a permanent injunction, court order, or final court decision that prohibits in whole or in part the collection of taxes under RCW 82.65A.030.

*Reviser's note: "Section 7 of this act" was originally an appropriation section, however a senate amendment removed the appropriation section, and the corresponding internal and substantive references were not corrected.
