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 Secretary or the Game Management Authority (as appropriate) for a variation of authority for any one or more of the following purposes—

to extend the period of validity of the authority;

to authorise additional or alternative persons to engage in controlled conduct for the purposes of the operation;

to authorise participants in the operation to engage in additional or alternative controlled conduct;

to identify additional suspects (to the extent known).

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 3 months at a time.

An application for a variation of authority must be in writing signed by the applicant.

The Secretary or the Game Management Authority (as appropriate) may require the applicant to furnish such information concerning the proposed variation as is necessary for the proper consideration of the application.
