If an individual, elected or appointed as a member of council and notified of election or appointment refuses or neglects to qualify as a member of council within ten days following the beginning of the individual's term of office, unless prevented by sickness or necessary absence from the borough, the council, acting without the individual, may declare the individual's office as member of council vacant and may fill the vacancy as provided in section 901 (relating to filling vacancies in elective borough offices). For these actions, a majority of the remaining members of the council shall constitute a quorum.
