(1) An eligible person (within the meaning of subsection 175(2) or 176(2), as the case requires) must not make an authorisation under Division 3 that would authorise the disclosure of information or documents relating to a particular person if:
(a) the eligible person knows or reasonably believes that particular person to be:
(i) a person who is working in a professional capacity as a journalist; or
(ii) an employer of such a person; and
(b) a purpose of making the authorisation would be to identify another person whom the eligible person knows or reasonably believes to be a source;
unless a journalist information warrant is in force in relation to that particular person.
(2) Nothing in this section affects by implication the kind of person in relation to whom a warrant (other than a journalist information warrant) may be issued under this Act.
