Summary


Assembly Constitutional Amendment 13 (ACA 13) would require initiated constitutional amendments proposing increased voter approval requirements for state or local measures to be approved by the same majority requirement it is proposing. For example, an amendment proposing a two-thirds (66.67%) vote must also be approved by two-thirds of voters. Currently, initiated constitutional amendments need to be approved by a simple majority.[2]

The amendment would also authorize local governing boards (boards of supervisors, city councils, or school boards) to place advisory questions on local ballots to determine the electorate's opinion on a policy. The advisory questions would not be legally binding.

Measure Text


Sec. 10 of Article II

(a) An initiative statute or referendum approved by a majority of votes cast thereon the electors pursuant to Section 10.5 takes effect on the fifth day after the Secretary of State files the statement of the vote for the election at which the measure is voted on, but the measure may provide that it becomes operative after its effective date. If a referendum petition is filed against a part of a statute the remainder of the statute shall not be delayed from going into effect.

(b) If provisions of two or more measures approved at the same election conflict, the provisions of the measure receiving the highest number of affirmative votes shall prevail.

(c) The Legislature may amend or repeal a referendum statute. The Legislature may amend or repeal an initiative statute by another statute that becomes effective only when approved by the electors unless the initiative statute permits amendment or repeal without the electors’ approval.

(d) Before circulation of an initiative or referendum petition for signatures, a copy shall be submitted to the Attorney General who shall prepare a title and summary of the measure as provided by law.

(e) The Legislature shall provide for the manner in which a petition shall be circulated, presented, and certified, and the manner in which a measure shall be submitted to the electors.

Sec. 10.5. (a) Except as provided in subdivision (b), a statewide initiative statute or referendum is approved if a majority of the votes cast on the measure are in favor.

(b) Notwithstanding Section 4 of Article XVIII or any other provision of the Constitution, an initiative measure that includes one or more provisions that amend the Constitution to increase the voter approval requirement to adopt any state or local measure is approved by the voters only if the proportion of votes cast in favor of the initiative measure is equal to or greater than the highest voter approval requirement that the initiative measure would impose for the adoption of any state or local measure.

(c) This section applies to all statewide initiative measures submitted to the electors on or after January 1, 2024, including measures that appear on the ballot at the same election at which the measure adding this section is approved by the electors.

Article XI

Sec. 7.8. At any election, pursuant to procedures that the Legislature shall provide, a local governing body may hold an advisory vote concerning any issue of governance for the purpose of allowing voters within the jurisdiction to voice their opinions on the issue. An advisory question is approved only if a majority of the votes cast on the question are in favor. The results of the advisory vote shall in no manner be controlling on the sponsoring local governing body.
