HJR 18 -- Initiative Petitions Sponsor: Davis Upon voter approval, this constitutional amendment modifies the process for accepting and enacting constitutional amendments. Proposed amendments will not be submitted to voters if any person, group, or entity has been paid to gather signatures for the initiative petition. Constitutional amendments submitted by either the General Assembly or by initiative petition will require a two-thirds majority vote to become law. However, constitutional provisions enacted on or after November 1, 1998, but before November 2, 2008, may be repealed by a constitutional amendment that receives a simple majority vote.Copyright (c) Missouri House of Representatives
