    See also: Legislative alteration rules

    Legislative alteration refers to when lawmakers repeal or amend citizen initiatives after voters have approved them. At the statewide level, it applies only to initiated state statutes since legislatures cannot change initiated constitutional amendments without voter approval. There are 21 states with a process for initiated state statutes. Eleven states have no restrictions on legislative alteration, two states—Arizona and California—require voter approval of substantive alteration, and the remaining eight states have either time restrictions, supermajority vote requirements, or a combination of the two. Click here to read more about the rules in each state.

    Legislative alterations vary with regard to how they affect the provisions of the initiatives. Some alterations repeal or amend provisions in ways that are opposed to the original initiative and/or the purpose of initiative proponents. Some alterations change technical aspects of the policy or details of regulation rather than changing significant substantive provisions. And some alterations change certain provisions to allow for enforcement, to fix errors, to strengthen provisions, or to otherwise further the purpose of the original initiative and initiative proponents.

    There are other related legislative or state official actions regarding citizen initiatives that do not involve directly altering the laws enacted by the measures. These include compromises with initiative proponents prior to the election, actions to preclude an election on the proposed initiative, the details of implementation, and varying degrees of enforcement.

    Alterations by state

    Alaska

    See also: Alaska ballot measures

    In Alaska, two years must elapse before the legislature can repeal an initiated state statute. The legislature is allowed to amend an initiative with a simple majority vote at any time.

    From 2010 through 2024, Alaska voters approved 13 initiated state statutes. None of the initiatives were legislatively altered directly, although the legislature passed bills regulating marijuana legalization and allocating marijuana tax revenue in 2016 and 2018 that were related to the 2014 marijuana legalization initiative.

    Arizona

    See also: Arizona ballot measures

    In Arizona, the legislature can make changes to an initiated state statute that are in line with the purpose of the initiative through a three-fourths supermajority vote. Any substantive changes must be submitted to the voters through a legislatively referred state statute. Therefore, the Arizona State Legislature is prohibited from substantive legislative alteration without voter approval. California is the only other state with a provision requiring voter approval for changes to initiated state statutes, but California's requirement applies to all changes not only substantive ones.

    From 2010 through 2024, Arizona voters approved eight initiated state statutes. Including prior to 2010, two Arizona ballot initiatives were legislatively altered, with one altered multiple times. The alterations were not sent to the ballot for voter approval. The legislative alterations of these two initiatives were declared unconstitutional by court rulings due to the state's restrictions on legislative alteration, and the original initiatives were restored.

Both alterations were passed as measures to further the purpose of the initiatives and were, therefore, not referred to the voters.

    See also: Nevada ballot measures

    In Nevada, three years must pass before the state legislature amends or repeals a citizen initiative.

    From 2010 through 2024, Nevada voters approved four initiated state statutes. Of those, one was legislatively altered: Question 1, a 2016 initiative to establish background check requirements for gun purchases. The initiative was not implemented because it required background checks to go through the FBI rather than the state's system, and the FBI did not participate in the expanded background checks. Following the election of Steve Sisolak (D) to succeed term-limited Brian Sandoval (R) as the state's governor and Aaron Ford (D) to succeed Adam Laxalt (R) as the state's attorney general, Senate Bill 143 was passed establishing that background checks for gun purchases would go through the state's system rather than through the FBI, therefore allowing Question 1 to be implemented.

    Question 1 was added to state code on November 22, 2016. SB 143 included a provision stating that the bill would take effect on January 2, 2020, to satisfy the state's requirement that three years elapse before an initiative is legislatively altered.
