(a) Members of council.--
(1) If a vacancy exists in the municipal council, the municipal council shall, by a majority of its remaining members, fill the vacancy within 30 days thereafter by electing a qualified person to serve until that first Monday of January when his successor is duly sworn into office for the remainder of the term of the person originally elected to the office. The successor shall be elected at the next municipal election occurring at least 50 days after the vacancy begins.
(2) In case vacancies should exist whereby the offices of a majority or more members of the municipal council become vacant, the remaining members shall fill the vacancies, one at a time, giving each new appointee reasonable notice of his appointment as will enable him to meet and act with the then qualified member or members of the municipal council in making further appointments until a bare majority of members of municipal council members have been qualified. At that time these members shall appoint persons to fill the remaining vacancies at a meeting attended by the majority members of municipal council, such appointees to receive a majority of the votes of the members present at the meeting. Each person selected to fill the vacancy or vacancies shall hold his office as provided in this subsection.
(3) If, by reason of a tie vote or otherwise, the vacancy shall not have been filled by the remaining members of municipal council within the time as limited in this subsection, the court of common pleas upon the petition of ten or more qualified electors shall fill the vacancy by the appointment of a qualified person for the portion of the unexpired term as provided in this subsection.

The person so elected shall serve from the first Monday of January next succeeding his election for the remainder of the term of the person originally elected to the office.
(2) If, by reason of a tie vote or otherwise, a vacancy in the office of executive (mayor), treasurer, controller, county district attorney or county sheriff has not been filled by council within the time as limited in this subsection, the court of common pleas, upon petition of ten or more qualified electors, shall fill the vacancy by the appointment of a qualified person for the portion of the unexpired term as provided in this subsection.
