§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 sections to Article III making initiative and referendum fundamental rights, barring the legislature from passing or referring measures that weaken those powers, requiring an 80 percent vote of each chamber to send voters any change to a citizen-initiated law or amendment, letting courts rewrite ballot summaries, and writing the current signature and simple-majority rules into the constitution.2 Where in the source: New art. III, §§ 54 to 58

A no vote would leave the constitution without these sections, so the legislature could still change citizen-initiated laws and could still propose constitutional amendments, including ones on the petition process, with a majority of the members of each house, while the current signature and majority rules stay as they are.2,
