Except as otherwise provided in this division, when the office of a member of the Council of the City becomes vacant, either because a member ceases to hold office before the end of the members term or because a member-elect fails to take office, the vacancy shall be filled for the remainder of the unexpired term by a person chosen by the residents of the City who are members of the county central committee of the political party by which the last occupant of that office or the member-elect was nominated.
   Not less than five (5) or more than forty-five (45) days after a vacancy occurs, the specified members of the City or county committee shall meet to make an appointment to fill the vacancy. At least four (4) days before the date of such meeting, the chairperson or secretary of the City or county committee shall notify each committee member eligible to vote on filling the vacancy, by first class mail, of the date, time, and place of the meeting and its purpose. A majority of all eligible committee members constitutes a quorum and a majority of the quorum is required to make the appointment. If election to the office so vacated took place at a nonpartisan election, or if the office was occupied by, or was to be occupied by a person not nominated at a primary election, or if the appointment was not made by the committee members in accordance with this section, the vacancy shall be filled by a majority vote of the remaining members of the Council.
The Council shall determine its own rules and keep a journal of its proceedings. It may punish or expel any member for disorderly conduct or violation of its rules, and declare his seat vacant for absence without valid excuse, where such absence has continued for two months. No expulsion shall take place without the concurrence of two thirds (2/3) of all the members elected, and until the delinquent member has been notified of the charge against the member, and has had an opportunity to be heard.
