(1) A final order for the person starts to have effect when it is made.
Note--
The order comes into force when it is made. The period for which the person may be detained under the order, however, only starts to run when the period during which the person may be detained under any other preventative detention order, or order for the detention of the person under a corresponding law, ceases to have effect (see section 25(4)(a)).
(2) A final order for the person ceases to have effect when whichever of the following first occurs--
(a) the end of--
(i) the period stated in the order as the period during which the person may be detained under the order; or
(ii) if that period is extended or further extended under section 31--that period as extended or further extended;
(b) the revocation of the order under division 5.
Note--
The order does not cease to have effect merely because the person is released from detention under the order. See section 45.
