Modifies provisions relating to municipal elections

SB 1152 modifies Missouri's municipal election rules, primarily affecting small cities and towns with 2,000 or fewer residents. It establishes a "no-election" rule: if the number of candidates for an office exactly matches the positions to be filled in such small jurisdictions, candidates automatically assume office without a vote, with notice published in a local newspaper. The bill also changes vacancy procedures (requiring mayoral appointments with council approval for non-mayor roles) and standardizes election dates (general municipal elections in April, primary elections in August). Additionally, it updates candidate filing requirements to include party affiliation on declarations of candidacy.
