Constitution of the State of Montana

1972

Montana adopted its current constitution on June 20, 1972, replacing the original 1889 document that had governed the state since it joined the Union. The convention that drafted it was notable for its openness — sessions were televised and public participation was actively encouraged, making it one of the most transparent constitutional conventions in American history. The resulting document strengthened individual rights, established an explicit right to a clean and healthful environment, and streamlined state government. It remains one of the more modern and progressive state constitutions in the country.
