Saving the validity of acts done by authorities
(1) Subject to section 19E, the purported exercise or performance of a power, function or duty by or on behalf of an authority (see subsection (5)) is not invalid merely because, following a machinery of government change, the power, function or duty:
(a) is conferred or imposed on another authority; or
(b) is conferred or imposed on the same authority under another name or title; or
(c) is no longer conferred or imposed on any authority.
(2) Subsection (1) only applies if the authority acted on the basis of a reasonable, but mistaken, belief about the occurrence, timing or nature of the machinery of government change.

(b) the name or title of the authority is changed;
(c) there is a change in the matters dealt with by the authority because of the effect of an Administrative Arrangements Order;
(d) the authority no longer exercises or performs the power, function or duty for any other reason.
Powers, functions and duties
