What is the process of amending the Missouri Constitution initiated by?

The process of amending the Missouri Constitution is initiated by a majority vote of the members of each house of the Missouri legislature. This mechanism allows the legislature to propose amendments that reflect the will of the elected representatives.

Once an amendment is proposed through this legislative process, it is then submitted to the voters for approval or disapproval during an election. This establishes a clear pathway where both legislative action and public consent are involved in constitutional amendments. The requirement of a majority from both houses ensures that any proposed changes have broad legislative support before reaching the electorate, thereby maintaining a level of stability and deliberation in the constitutional amendment process.

The other options do not align with the established procedure: a two-thirds public vote is not a requirement for initiation; a simple majority from the governor does not grant authority to propose amendments; and county officials do not have the authority to initiate a referendum for constitutional changes.
