In NSW the SSMA 1996 says:
- (2) When a vacancy occurs in the office of a member of an executive committee (otherwise than by reason of subclause (1) (d)), the owners corporation must appoint a person eligible for election as a member to fill the vacancy. Any person so appointed holds office, subject to this clause, for the balance of his or her predecessor’s term of office.
I guess you could call an Extraordinary General Meeting (EGM) and replace the vacancy there. How soon should that be done? The act does not say how soon, however like everything else it should be done as soon as practicable.
