Materials not disclosed - an invalid certificate
32 One final matter should be briefly mentioned.
33 Those appearing for the Respondent Minister have quite properly disclosed to the Court that some materials were made available to the Tribunal but not the Appellant. That material had been the subject of certificates purportedly issued under s 438(1)(a) and (b) of the Migration Act 1958 (Cth) (the "Migration Act").
34 Section 438 provides in relevant part as follows:
Tribunal's discretion in relation to disclosure of certain information etc.
(1) This section applies to a document or information if:
(a) the Minister has certified, in writing, that the disclosure of any matter contained in the document, or the disclosure 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 437(a) or (b)) that 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; or
(b) the document, the matter contained in the document, or the information was given to the Minister, or to an officer of the Department, in confidence.
(2) If, in compliance with a requirement of or under this Act, the Secretary gives to the Tribunal a document or information to which this section applies, the Secretary:
(a) must notify the Tribunal in writing that this section applies in relation to the document or information; and
(b) may give the Tribunal any written advice that the Secretary thinks relevant about the significance of the document or information.
(3) If the Tribunal is given a document or information and is notified that this section applies in relation to it, the Tribunal:
(a) may, for the purpose of the exercise of its powers, have regard to any matter contained in the document, or to the information; and
(b) may, if the Tribunal thinks it appropriate to do so having regard to any advice given by the Secretary under subsection (2), disclose any matter contained in the document, or the information, to the applicant.
…
35 Before this Court the Respondent Minister accepts that the certificates were "invalid".
36 The material the subject of the certificates was not adduced before the Federal Circuit Court. But the Respondent Minister wishes to adduce the materials before this Court. The forensic objective in doing so is to demonstrate that the materials could have been of no relevance to the decisions of the Tribunal or the Federal Circuit Court. Copies of the documents have been given to the Appellant.
37 Having considered the materials the subject of the certificates granted, albeit "invalidly", the irrelevance of that material to any issues raised in the proceeding before the Tribunal can safely be assumed. The disclosure of the material could not have impacted upon any consideration of any of the claims made by the now-Appellant and, moreover, could not have founded any argument having any prospect of success before either the Federal Circuit Court or this Court.
38 But the circumstances in which the certificates came to be issued raise more disturbing undercurrents of concern.
39 The case proceeded upon the basis that the documents the subject of the certificates comprised:
"a checklist concerning the validity of the appellant's first protection visa application";
"a checklist as to the validity of his bridging visa application";
"a file management checklist";
"the appellant's movement history";
"a checklist as to the validity of the appellant's second protection visa application";
"an identification checklist"; and
"an interpreter service delivery form".
The documents were - at best - neutral to any question as to the credibility assessment of the Appellant as made by the Tribunal.
40 The very fact that the certificates had been issued by a delegate of the Minister, however, was truly worrying.
41 Why such documents as a "checklist" fell within the category of documents the disclosure of which "would be contrary to the public interest" was not self-evident. It was, perhaps, only a matter of chance that the character of the documents in respect to which the certificates in the present proceeding were issued came to be disclosed.
42 An opportunity was thus extended to the Respondent Minister to explain the basis upon which the certificates had first been issued and the administrative steps that have since been taken to ensure that any future certificates are only issued after a proper consideration of the requirements imposed by s 438.
43 Public confidence, let alone judicial confidence, in the integrity with which the Migration Act is being administered by the Minister and his delegates is only seriously undermined if the public and this Court are left with a disturbing concern as to whether certificates are being issued without any reasonable basis for doing so. Indeed, there is a "presumption of regularity" as to the circumstances in which a statutory power is exercised: Industrial Equity Ltd v Deputy Commissioner of Taxation (1990) 170 CLR 649 at 672 per Gaudron J. An exercise of statutory power may ultimately be found to be unlawful after judicial scrutiny; but the integrity with which the power is being exercised should always be assumed.
44 Where, as in the present case, it would appear that the statutory power conferred by s 438 was exercised upon no sustainable basis, that integrity is necessarily called into question and the assumption prejudiced.
45 The manner in which the certificates in the present proceeding were issued fell seriously short of the standard expected of a proper exercise of power. The independent solicitors retained by the Minister in the present proceeding are to be commended for bringing to the attention of the Court the question as to the appropriateness of the certificates having been issued. It is the Minister, of course, and the Minister alone who remains accountable for such a shortcoming in the manner in which the Act was administered by his Department.
46 At a subsequent hearing following an adjournment to allow time (inter alia) to address the issue of the certificates, two relevant submissions emerged, namely:
there was no explanation for the circumstances in which the decision was made to issue the s 438 certificates - other than the recital in those certificates that the documents were "internal working documents"; and
the Department has since issued a Guidance addressing the bases upon which such certificates are now issued, which provides that designating documents as "internal working documents" is not a sufficient reason in itself to issue a certificate.
47 Although the certificates identified that both sub-ss 438(1)(a) and (b) applied, no submissions were directed to sub-s (b).
48 The concern previously expressed as to the lack of a substantive basis upon which the certificates were issued in the present proceeding and the materials initially withheld from the Appellant is repeated. A mere designation that documents are "internal working documents", without any further consideration being given to the content of such documents and whether disclosure would be "contrary to the public interest", falls well short of the task required to be undertaken by s 438 of the Migration Act.
49 The new Guidance properly recognises the constraints imposed by s 438.
50 It should be noted that there are presently pending before this Court a number of other proceedings in which the potential impact of certificates having been issued under s 438 of the Migration Act is to be considered. Notwithstanding that those other proceedings have been or are soon to be heard, it is considered appropriate to nevertheless now publish reasons and make orders in the present proceeding. Even assuming there to have been a denial of procedural fairness to the present Appellant by reason of the materials not having been disclosed, there is no basis upon which any contrary conclusion would have been reached in the present proceeding. The arguments sought to be relied upon, assuming an extension of time was granted, were without merit.
