Changes the laws regarding cities of the fourth classification

HB 1635 updates the laws governing Missouri's fourth-class cities by repealing existing statutes and replacing them with new provisions. The bill grants these cities the authority to expand or shrink their boundaries with voter approval and allows local boards to set their own terms for mayors and aldermen, ranging from two to four years. It also clarifies election rules, permitting smaller cities to elect aldermen at large rather than by ward, and establishes that city officials generally serve without compensation or employment benefits. Additionally, the legislation outlines procedures for passing ordinances, requiring a majority vote and specific reading steps before a bill becomes law.
