This bill establishes a framework for the periodic review of new statutory state spending programs in Washington. It mandates that every new spending program must include an expiration date not exceeding ten years from its effective date, and any amendments that modify or expand the program will not extend this expiration unless explicitly stated. The bill defines a "new statutory state spending program" as one that begins after January 1, 2026, involves significant state expenditures exceeding $1,000,000, and is not self-supported by fees. Additionally, each new program must include a state spending performance statement that outlines its legislative purpose and specifies measurable metrics for evaluating its effectiveness.

The bill also requires the joint legislative audit and review committee to conduct reviews of these new spending programs based on a developed schedule, considering various factors such as public policy objectives, evidence of effectiveness, and fiscal impacts. The committee will provide recommendations on whether to continue, modify, or terminate the programs based on their performance against the established metrics. If a program lacks the required performance statement, it is presumed to be intended for expiration on its scheduled date. The bill adds new sections to Title 43 RCW and includes a provision ensuring that if any part of the act is deemed invalid, the remaining sections will still be effective.
