(1) The chief officer of an agency must periodically review each authority granted by the chief officer or a delegate of the chief officer under this Part.
(2) A review of an authority under this section is to be conducted:
(a) in the case of an authority granted by the chief officer or a delegate of the chief officer of an intelligence agency to an authorised intelligence officer--at least once every 3 years; or
(b) in all other cases--at least once every 12 months.
Note: Section 15KW modifies the effect of this provision if control of the authority is transferred.
(3) The purpose of a review is to determine whether use of the assumed identity under the authority is still necessary.
(4) If the chief officer is satisfied on a review that use of the assumed identity under the authority is no longer necessary, he or she must cancel the authority under section 15KE.
(5) If the chief officer is satisfied on a review that use of the assumed identity under the authority is still necessary, he or she must record his or her opinion, and the reasons for it, in writing.
Note: The chief officer may delegate functions under this section--see section 15LH.
(6) Failure to comply with the requirements of this section does not invalidate an authority or anything lawfully done under the authority.
