Acts Interpretation Act 1954

This section applies if an Act provides that a specified officer, or the holder of a specified office, (the nominated person) acts as another specified officer or in another specified office on a specified occasion.

While the nominated person is acting as the other officer or in the other office—

the nominated person has all the functions and powers of the officer or holder of the office; and

laws apply to the nominated person, and to other persons in relationship to the nominated person, as if the nominated person were the officer or holder of the office.

Anything done by or in relation to the nominated person while the nominated person is purporting to act as the other officer or in the other office is not invalid merely because the occasion for the nominated person to act had not happened or had ceased.
