§1What your vote means

Drafted by AI from the public sources cited. Each sentence links to its source.

A yes vote

A yes vote would add rules for the initiative and referendum process to the constitution, such as approving petitions and ballot statements within 90 days, settling qualification challenges before ballots are final, not rejecting petitions over minor technical issues, and barring government resources for or against a ballot measure.1 Ballot Issues, Constitutional Initiative No. 133

A no vote

A no vote would leave the constitution's initiative and referendum sections unchanged, so petition review, deadlines and court challenges would keep following the procedures set in current state statutes.2,3 Mont. Const. art. III, § 4; MCA Title 13, chapter 27
