For more on that question, check out CLEAN v. State, 130 Wash.2d 782 (1996). The Stadium Act provided public financing for the construction of Safeco Field, and included an "emergency clause" which shields legislation from referendum. Emergency clauses declare an act "necessary for the immediate preservation of the public peace, health or safety, support of the state government and its existing public institutions." The Supreme Court upheld that particular emergency declaration.
