JEFFERSON CITY, Mo. — Missouri voters approved Constitutional Amendment 6 in Tuesday’s election, adopting additional protections for the state’s citizen initiative and referendum process.

Unofficial statewide results posted by St. Charles County show 1,251,555 votes in favor and 835,585 against. In St. Charles County, the measure passed 99,504 to 64,562.

The amendment is intended to limit the legislature’s ability to weaken petition and referendum powers and make it harder to change laws enacted through citizen initiatives.

Final results remain subject to the statewide certification process. The outcome reflects voters’ continued interest in the rules governing direct democracy in Missouri.
