(1) In so far as a listing under section 15 gives effect to a particular decision of the Security Council, the listing is revoked when Article 25 of the Charter of the United Nations ceases to require Australia to carry out that decision.
(2) In so far as regulations proscribing a person or entity under section 18 give effect to a particular decision of the Security Council:
(a) the regulations cease to have effect when Article 25 of the Charter of the United Nations ceases to require Australia to carry out that decision; and
(b) they do not revive, even if Australia again becomes required to carry out the decision.
(3) However, to avoid doubt, nothing in this section prevents:
(aa) a listing ceasing to have effect under section 15A; or
(a) the revocation, under section 16, of a listing; or
(b) the repeal of regulations; or
(c) the making of regulations that are the same in substance as regulations that have ceased to have effect because of this section.
