Colorado Constitution

The Constitution of the State of Colorado is the foundation of the laws and government of the state of Colorado. The current, and only, Colorado State Constitution was drafted March 14, 1876, approved by Colorado voters July 1, 1876, and took effect upon the statehood of Colorado on August 1, 1876. It has been amended several times since then.
