Constitution; amend Section 273 to reinstate initiative process and revise initiative signature requirements.

Mississippi bill SC 519 proposes a constitutional amendment to reinstate the citizen initiative process for proposing constitutional changes, which was previously invalidated by the Mississippi Supreme Court. It requires initiatives to gather signatures from 40% of registered voters (instead of previous thresholds), mandates inclusion of petitioners' full home addresses, and limits signatures per congressional district to ensure statewide distribution. The bill also specifies that each initiative petition must contain only one proposal with full text, revenue sources, and fiscal impact details, while prohibiting initiatives on certain topics like the Bill of Rights or retirement systems. This would directly affect Mississippi voters seeking to bypass the legislature and propose constitutional amendments through petitions.
