(1) After considering an application for approval of an emergency authorisation given under section 343 , the judge may approve the application if satisfied that there were reasonable grounds to believe that—(a) there was a risk of serious violence to a person or substantial damage to property; and(b) using a surveillance device may have helped reduce the risk; and(c) it was not practicable in the circumstances to apply for a surveillance device warrant.
(2) If the judge approves an application under this section, the judge may issue a surveillance device warrant for the continued use of the surveillance device as if the application were an application for a surveillance device warrant under part 2 , division 2 .
(3) If the judge does not approve an application under this section, the judge may—(a) order that the use of the surveillance device cease; and(b) authorise, on conditions the judge considers appropriate, the retrieval of the surveillance device.
(4) In any case, the judge may order that any information obtained from or relating to the exercise of powers under the emergency authorisation or any record of that information be dealt with in the way stated in the order.
