A superseding initiative is the initiative that prevails when two or more conflicting initiatives are approved at the same election. There are two common approaches to resolving the outcome when two conflicting initiatives are both approved. In some states, the measure with the most affirmative votes takes effect and the other measures do not. In other states, the measure with the most affirmative votes prevails only on points of conflict.

HIGHLIGHTS
  • Seventeen (17) of the 25 states with active initiative and referendum processes have statutory or constitutional provisions addressing superseding initiatives.
  • Related legislation: In 2018, South Dakota passed Senate Bill 10 to provide that when initiated measures or constitutional amendments passed at the same election conflict with one another, the measure receiving the highest number of votes becomes enacted.
  • Requirements by state

    Seventeen (17) states have statutory or constitutional provisions addressing superseding initiatives, including:

    • Eight states provide that the entire ballot initiative that received the most affirmative votes supersedes the competing initiative;
    • Seven states provide that the initiative with the most affirmative votes supersedes the competing initiative on any points of conflict; and
    • Two states—Maine and Washington provide that the ballot be organized so voters must choose between the two or neither.

    Eight states do not provide any provisions addressing superseding initiatives.

    • Utah House Bill 133: The legislation modified the effective dates for voter-approved ballot initiatives. HB 133 provided that the effective date is at 60 days following the last day of the legislative session immediately after the election in which the initiative is approved, except for certain tax-related initiatives. Under HB 133, a tax increase initiative goes into effect on January 1 of the year following the next general legislative session after the election. A tax decrease goes into effect five days after the governor issues the proclamation of election results for the initiative. HB 133 also allowed courts, in addition to the Utah Supreme Court, to consider challenges regarding conflicts between two measures.[1]
