31.3. Where an office must be held for a period of two years by the mayor of a municipality in category 2 or 3, the holder of the office must be designated before the beginning of that period.
If the holder of the office is not designated before the beginning of the period, the mayor of the municipality in the category concerned holding one of the other offices at the end of the preceding period shall become the holder of the unfilled office for the period in question.
If, at any time during the period, the Act respecting elections and referendums in municipalities (chapter E-2.2) disqualifies the holder of the office from attending meetings of the Council as a member thereof, he may be replaced, for the duration of the disqualification within the period, by another mayor designated in accordance with section 31.2.
