(1) The purpose of
this section is to ensure that this Part operates to give to an
invalid administrative action that has subsequently been affected by another
action or process no greater effect than it would have had if the
administrative action, or any other relevant administrative action, had not
been invalid on constitutional grounds (arising from the circumstances
referred to in paragraphs (a) and (b) of the definition of “invalid
administrative action” in section 3).
(2) If
administrative action taken by a Commonwealth authority or an
officer of the Commonwealth was affected (whether by way of revocation,
modification or otherwise) at or before the commencement time in relation to a
relevant State Act by any later administrative action or by any judicial
process or by any administrative review process, this Part applies to the
administrative action as so affected from time to time.
(3) In this section, a
reference to administrative action taken includes a reference to
administrative action purportedly taken, and a reference to
administrative action affected in any way includes a reference to
administrative action purportedly affected in that way.
