the subject may be prevented from contacting a particular lawyer of the subject's choice if the prescribed authority concerned so directs.
(2) The prescribed authority may so direct only if the authority is satisfied, on the basis of circumstances relating to that lawyer, that, if the subject is permitted to contact the lawyer:
(a) a person involved in a terrorism offence may be alerted that the offence is being investigated; or
(b) a record or thing that the person may be requested in accordance with the warrant to produce may be destroyed, damaged or altered.
(3) This section has effect despite paragraph 34K(11)(a).
(4) To avoid doubt, subsection (1) does not prevent the subject from choosing another lawyer to contact, but the subject may be prevented from contacting that other lawyer under another application of that subsection.
