(a) the instrument or decision was made:
(i) on or after the time that the National Energy Retail Law (South Australia) Act 2011 of South Australia was enacted; but

(b) the making of the instrument or decision would have been authorised by the National Energy Retail Law and Regulations (Commonwealth) (the authorising law ) if the South Australian Energy Retail Legislation had started so to apply; and
(c) in a case in which the making of the instrument or decision would be so authorised subject to the satisfaction of any conditions or other requirements (for example, consultation or publication requirements)--the Australian Energy Regulator has done anything that would, if the South Australian Energy Retail Legislation had started so to apply, be required under the authorising law for the instrument or decision to be so authorised.
(2) For the purposes of the authorising law:
(a) the instrument or decision is taken to be valid; and

(i) as varied, and unless revoked, by any other instrument or decision to which this section applies; and
(ii) subject to that law as so applying.
