Relevant provisions
11 Part 5 of the Act deals with the review of decisions. Division 5 of Part 5 deals with the conduct of such reviews. Section 357A is of particular importance. It provides:
'(1) This division is taken to be an exhaustive statement of the requirements of the natural justice hearing rule in relation to the matters it deals with.
(2) Sections 375, 375A and 376 and Division 8A, in so far as they relate to this Division, are taken to be an exhaustive statement of the requirements of the natural justice hearing rule in relation to the matters they deal with.'
12 I will return to that section at a later stage.
13 Section 359A of the Act provides:
'(1) Subject to subsection (2), the Tribunal must:
(a) give to the applicant, in the way that the Tribunal considers appropriate in the circumstances, particulars of any information that the Tribunal considers would be the reason, or a part of the reason, for affirming the decision that is under review; and
(b) ensure, as far as is reasonably practicable, that the applicant understands why it is relevant to the review; and
(c) invite the applicant to comment on it.
(2) The information and invitation must be given to the applicant:
(a) except when paragraph (b) applies - by one of the methods specified in section 379A; or
(b) if the applicant is in immigration detention - by a method prescribed for the purposes of giving documents to such a person.
(4) This section does not apply to information:
(a) that is not specifically about the applicant or another person and is just about a class of persons of which the applicant or other person is a member; or
(b) that the applicant gave for the purpose of the application; or
(c) that is non- disclosable information.'
There is apparently no subsection 359A(3).
14 Section 379A prescribes a number of methods for delivering a document to a person for the purposes of the Act. However s 359A is concerned expressly with information rather than documents. Perhaps ss 359A and 379A, together, require that the Tribunal reduce to writing the information identified in s 359A and supply the outcome to the applicant by one of the methods identified in s 379A. I will assume such an effect for present purposes. Paragraph 359A(4)(c) speaks of "non-disclosable information". That term is defined in s 5 as follows:
'non-disclosable information means information or matter:
(a) whose disclosure would, in the Minister's opinion, be contrary to the national interest because it would:
(i) prejudice the security, defence or international relations of Australia; or
(ii) involve the disclosure of deliberations or decisions of the Cabinet or of a committee of the Cabinet; or
(b) whose disclosure would, in the Minister's opinion, be contrary to the public interest for a reason which could form the basis of a claim by the Crown in right of the Commonwealth in judicial proceedings; or
(c) whose disclosure would found an action by a person, other than the Commonwealth, for breach of confidence;
and includes any document containing, or any record of, such information or matter.'
15 Section 362A provides:
(1) Subject to subsections (2) and (3) of this section and sections 375A and 376, the applicant, and any assistant under section 366A, are entitled to have access to any written material, or a copy of any written material, given or produced to the Tribunal for the purposes of the review.
(2) This section does not override any requirements of the Privacy Act 1988. In particular, this section is not to be taken, for the purposes of that Act, to require or authorise the disclosure of information.
(3) This section does not apply if the Tribunal has given the applicant a copy of the statement required by subsection 368(1).'
16 The statement contemplated by s 368(1) is, in effect, a written statement recording the Tribunal's reasons for its decision. It may be that subs 362A(3) is intended to prescribe a time limit after which the Tribunal need not provide material.
17 Finally, s 375A provides:
(1) This section applies to a document or information if the Minister:
(a) has certified, in writing, that the disclosure, otherwise than to the Tribunal, of any matter contained in the document, or of the information, would be contrary to the public interest for any reason specified in the certificate (other than a reason set out in paragraph 375(a) or (b)); and
(b) has included in the certificate a statement that the document or information must only be disclosed to the Tribunal.
(2) If, pursuant to a requirement of or under this Act, the Secretary gives to the Tribunal a document or information to which this section applies:
(a) the Secretary must notify the Tribunal in writing that this section applies to the document or information; and
(b) the Tribunal must do all things necessary to ensure that the document or information is not disclosed to any person other than a member of the Tribunal as constituted for the purposes of the particular review.'
18 This section should be construed in the light of ss 375 and 376. The Minister may certify, pursuant to s 375, that the disclosure of particular documents or information would be contrary to the public interest because of possible prejudice to security, defence or international relations or because it would involve disclosure of the deliberations of Cabinet or a Cabinet committee. Such material will not be provided to the Tribunal. Subparagraphs (a)(i) and (ii) of the definition of "non-disclosable information" would seem to include this material which would therefore be exempted by par 359A(4)(c) from the operation of s 359A.
19 Pursuant to s 376 the Minister may certify that disclosure will be contrary to the public interest for a reason (other than a reason set out in s 375) which 'could form the basis for a claim by the Crown in right of the Commonwealth in a judicial proceeding that the matter contained in the document, or the information, should not be disclosed ...'. Such material would presumably also fall within par (b) of the definition of "non-disclosable information" and therefore be exempted by par 359A(4)(c) from the operation of s 359A. In the case of such a certificate the Tribunal may disclose the relevant material to the applicant or to other persons giving evidence.
20 Section 375A authorizes the Minister to certify that material should not be disclosed, other than to the Tribunal, upon the ground that such disclosure would be contrary to the public interest for any reason other than one of the reasons set out in s 375. In the event of such a certificate being issued, the Tribunal is obliged to do everything necessary to ensure that neither the documents containing the information, nor the information is disclosed to any person other than a member of the Tribunal constituted for the purposes of the review in question. The Tribunal has no discretion in the matter. Such material may, in some cases, also fall within par (b) or (c) of the definition of "non-disclosable information" and therefore be exempted by par 359A(4)(d) from the operation of s 359A, depending upon the Minister's reason for issuing the certificate. However the Minister may conceivably act upon a basis which does not fall within those paragraphs. In that case, par 359A(4)(c) would not exempt the material from the operation of s 359A.
21 It is curious that material which is the subject of a certificate under s 375A is not expressly excluded from the operation of s 359A. Nonetheless, the obligation to maintain secrecy imposed upon the Tribunal by s 375A is so specific that the obligation imposed by s 359A must give way to it. This would, in my opinion, be so, even in the absence of s 357A. However that section puts the matter beyond doubt. The obligation conferred upon the Tribunal by s 362A must similarly yield to that imposed by s 375A.
