The Official Administrator’s appointment has been amended with new authority to act as council, and an interim CAO appointed to oversee the management of city operations, until a byelection is held, quorum is restored, and the new council can recruit a permanent CAO. Since council has lost quorum, the three remaining councillors will have no role in city governance until the byelection is held and quorum is restored.
