(1) An order made
under this Act by the Governor or the Minister is required to be published in
the Gazette and takes effect on the day of publication or, if another day is
specified in the order, on the day specified.
(2) Power given by
this Act to the Governor or the Minister to make an order includes power from
time to time —
(a) to
revoke or cancel the order wholly or in part, with or without substituting
another order; and
(b) to
otherwise vary the order,
unless the terms used
in conferring that power, or the nature of the subject matter, or the objects,
of that power indicate that it is intended to be exercised finally and
irrevocably in the first instance.
(3) An order which
purports to be made under this Act, and which is within the powers conferred
on the Governor or the Minister by this Act, is not invalid because of
non-compliance with a matter required by this Act to be complied with before
making the order.
