This bill amends Washington state law to lower the voter approval threshold for school district bond measures from three-fifths to a simple majority in several contexts. Specifically, it modifies requirements for validating indebtedness (RCW 28A.535.020), issuing bonds for capital purposes (RCW 84.52.056 and 39.36.020), issuing general obligation bonds (RCW 28A.530.020), and adjusting bonded indebtedness in school district reorganizations (RCW 28A.315.285). The bill takes effect only if a companion constitutional amendment authorizing simple-majority approval for school district bonds is approved by voters at the next general election.
