Constitutional Amendment 6: Initiative and Referendum Petition Process
Source: ky3.com
What does this measure do?
The legislature could not change or repeal a law that voters passed by petition unless 80% of both chambers agree and voters approve. It also makes the petition process a basic right and keeps today's signature and majority-vote rules; the state says it will not raise or lower taxes.

Proposed by: Citizen initiative by the Respect MO Voters coalition (petition 2026-106)
Faith, labor and community groups working together, co-founded by Benjamin Singer. They want to protect the citizen petition process from new limits.

A YES vote means
Lawmakers could not change voter-passed laws without an 80% vote of both chambers and a public vote, and could not pass laws that make petitions harder.
A NO vote means
The constitution stays the same. Citizens keep today's right to propose laws and referendums, and lawmakers can still change voter-passed laws.
