Proposes a constitutional amendment that modifies provisions for amending the constitution

HJR 77 proposes a constitutional amendment that would require initiative petitions for constitutional amendments to be signed only by U.S. citizens (currently allowing residents), reduce the required signatures from 8% to 7% of eligible voters across two-thirds of congressional districts, and change the approval threshold to require a majority of *all registered voters* (not just votes cast) for constitutional amendments passed via initiative. This directly affects citizens and groups seeking to place constitutional changes on the ballot through petitions. The amendment would also standardize petition requirements, including limiting amendments to one subject and mandating specific enacting clauses. It is a procedural change to Missouri's initiative process, not a substantive law.
