869.1. If, in a municipality in which an office of councillor must, pursuant to the Act governing it in that respect on 31 December 1987, be open for nominations after that date at a fixed-date election in a calendar year prior to that contemplated in section 869, an election for that office shall be held in that prior year.
The election is a regular election within the meaning of this Act and, except for sections 2 and 3, it applies to it. The date of the poll is that prescribed by the legislative or regulatory provision applicable to the municipality on 31 December 1987; if that date is not the first Sunday or Monday of November, sections 341 and 344 apply as if it were a by-election.
If the periodicity of elections observed by the municipality on 31 December 1987 and that provided for by the Act governing the municipality in that respect at that date do not coincide, the calendar year in which the election for the office of councillor is to be held is the year determined according to the periodicity observed by the municipality.
