Clause 60

Any casual vacancy arising among the elected members of the Council shall be filled with all convenient speed by the Council by the appointment of a person qualified under the provisions of section 54 of this Act as may be necessary, and any such new members shall hold office for so long as the member in whose place he is appointed would have held office.

The continuing members of the Council may act provided there is a quorum notwithstanding any vacancy in the Council and no act done by or by the authority of the Council shall be invalid in consequence of any defect that is afterwards discovered in the election or qualification of the members or any of them.
