# Voter Protection Act Arizona's Proposition 105, approved by voters in 1998 and now Ariz. Const. art. IV, pt. 1, § 1, ¶¶ 6 and 15. It is the strongest protection in the country for a law the voters wrote themselves. Under it, the Arizona legislature may not repeal a voter-approved measure at all; repeal requires going back to the voters. It may amend one only if the amendment **furthers the measure's own purpose** and passes by a **three-quarters supermajority of each house**. Anything more substantive must be referred to the ballot as a legislatively referred statute. A 2021 law requires that these restrictions be disclosed on the ballot and on the Secretary of State's website. The comparison that gives it meaning is stage 9 of [[How a Ballot Measure Gets on the Ballot]]: in eleven initiative states a legislature may amend or repeal a voter-approved statute immediately, by simple majority, with no waiting period at all. California's art. II, § 10(c) is the only comparable protection, and it can be waived by the measure itself.
