Industrial Relations Act 1996

If the Commission declares void the election of a person who has, since the election, purported to act in the office to which the person purports to have been elected, or declares such a person not to have been elected—

subject to a declaration under paragraph (b), all acts done by or in relation to the person that could validly have been done by or in relation to the person if the person had been duly elected are valid, and

the Commission may declare an act referred to in paragraph (a) to have been void, and, if the Commission does so, the act is taken not to have been valid.

If an election is held, or a step in relation to an election is taken, under an order of the Commission, the election or step is not invalid merely because of a departure from the rules of the organisation concerned that was required by the order of the Commission.
