Municipal term limits and election timing: five-year term, hearing before dissolution, and rules for post-dissolution elections. Article 243U fixes a Municipality's term at five years from its first meeting unless earlier dissolved with a reasonable opportunity to be heard; legal amendments cannot cut short a functioning Municipality's term. Elections must be completed before term expiry or within six months of dissolution, but no election is required if the remaining term is less than six months, and a reconstituted Municipality serves only the unexpired portion of the original term.
