Section 52 of the Principal Act is repealed and the following section is substituted:

52.     Witness privilege and production of documents

(1)  Neither the Crown or any other person is entitled to prevent or obstruct the provision of information or the production of any document or evidence from being given for the purpose of an investigation under this Act, notwithstanding any entitlement that might arise if the investigation were a legal proceeding held before a court.

(2)  A person is not excused from providing any information, producing any document or answering a question, when required to do so under this Act, on the ground that to do so would disclose legal advice furnished to a health service provider or other person to whom this Act applies.

(3)  Notwithstanding section 62B or anything in subsections (1) and (2) of this section, if the Attorney-General provides the Commissioner with a certificate that the disclosure of information concerning a specified matter (including the giving of information in answer to a question) or the disclosure of the contents of a specified document would be contrary to the public interest because the information or document would, if disclosed, prejudice the taking of proceedings for a crime or other offence, the Commissioner is not entitled to require a person to –

(a) provide the information; or

(b) answer questions concerning the matter or the document; or

(c) produce the document to the Commissioner.
