(1) The principal law
enforcement officer for an authorised operation, or any other law enforcement
officer on behalf of the principal law enforcement officer, may apply to the
authorising officer for a variation of authority for any one or more of the
following purposes —
(a) to
extend the period of validity of the authority (except as provided by
section 17(2));
(b) to
authorise additional or alternative persons to engage in controlled conduct
for the purposes of the operation;
(c) to
authorise participants in the operation to engage in additional or alternative
controlled conduct;
(d) to
identify additional suspects (to the extent known);
(e) if
the principal law enforcement officer has changed since the authority was
granted, to identify the new principal law enforcement officer.
(2) More than one
application for a variation may be made in respect of the same authority, but
no single variation may extend the period of validity of an authority for more
than 6 months at a time.
(3) An application for
a variation of an authority may be made —
(a) in
writing (a formal variation application ); or
(b)
orally (an urgent variation application ), if the applicant has reason to
believe that the delay caused by making a formal variation application may
affect the success of the operation.
(4) A formal variation
application must be in a physical form, signed by the applicant.
(5) However if it is
impracticable in the circumstances for a physical document to be delivered to
the authorising officer, a formal variation application 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
variation application may be made in person, by telephone or any other
electronic means.
(7) The authorising
officer may require the applicant to furnish such additional information
concerning the proposed variation as is necessary for the authorising
officer’s proper consideration of the application.
(8) As soon as
practicable after making an urgent variation application, the applicant must
make a record in writing of the application and give a copy of it to the
authorising officer.
