(1) The authorising
officer who grants an authority must cancel the authority if the authorising
officer is satisfied, on a review under section 53 or otherwise, that use of
the assumed identity is no longer necessary.
(2) The authorising
officer must give notice of the cancellation to —
(a) the
authorised person to whom it relates; and
(b) if
the authorised person is an authorised civilian, the authorised person’s
supervisor.
(3) The notice must be
given —
(a) in
writing (a formal cancellation of authority ); or
(b)
orally (an urgent cancellation of authority ), if the authorising officer is
satisfied that the delay caused by making a formal cancellation of authority
may affect the success of a law enforcement operation or is otherwise urgently
required.
(4) A formal
cancellation of authority must be in a physical form, signed by the
authorising officer.
(5) However if it is
impracticable in the circumstances for a physical document to be given to the
authorised person or the authorised person’s supervisor (as the case
requires), a formal cancellation of authority may take the form of —
(a) a
fax; or
(b) an
email or other electronic document, in which case the document need not be
signed.
(6) An urgent
cancellation of authority may be made in person, by telephone or any other
electronic means.
(7) A cancellation of
authority takes effect —
(a) in
the case of a formal cancellation of authority in which a date of effect is
stated — on the day stated; or
(b) in
any other case — when it is given to the authorised person.
(8) A cancellation of
authority must —
(a)
identify the authorised person to whom the authority relates and, if the
authorised person is an authorised civilian, the authorised person’s
supervisor; and
(b)
state whether it is a formal cancellation of authority or an urgent
cancellation of authority; and
(c)
state the date and time when the cancellation of authority is or was made.
(9) The authorising
officer must, as soon as practicable after making an urgent cancellation of
authority, make a record in writing of the particulars referred to in
subsection (8) relating to the cancellation of authority.
