Ensuring all relevant material is available
46The heading to s 73 of the ADT Act is "Procedure of the Tribunal generally", but in some respects s 73 is more than procedural. It provides, for example, that the Tribunal is not bound by the rules of evidence and may inquire into and inform itself on any matter in such manner as it thinks fit, subject to the rules of natural justice: s 73(2); and that the Tribunal is to act informally and according to equity, good conscience and the substantial merits of the case without regard to technicalities or legal forms: s 73(3).
47Section 73(5) contains a collection of stipulations -
"(5) The Tribunal:
(a) is to act as quickly as is practicable, and
(b) is to ensure that all relevant material is disclosed to the Tribunal so as to enable it to determine all of the relevant facts in issue in any proceedings, and
(c) may require evidence or argument to be presented in writing and decide on the matters on which it will hear oral evidence or argument, and
(d) in the case of a hearing-may require the presentation of the respective cases of the parties before it to be limited to the periods of time that it determines are reasonably necessary for the fair and adequate presentation of the cases, and
(e) may require a document to be served outside the State, and
(f) may adjourn proceedings to any time and place (including for the purpose of enabling the parties to negotiate a settlement), and
(g) may dismiss at any stage any proceedings before it in any of the following circumstances:
(i) if the applicant (or, if there is more than one applicant, each applicant) withdraws the application to which the proceedings relate,
(ii) if the Tribunal considers that the proceedings are frivolous or vexatious or otherwise misconceived or lacking in substance,
(iii) if the applicant (or, if there is more than one applicant, each applicant) has failed to appear in the proceedings,
(iv) if the Tribunal considers that there has been a want of prosecution of the proceedings, and
(h) may reinstate proceedings that have been dismissed because of an applicant's failure to appear if the Tribunal considers that there is a reasonable explanation for that failure."
48Most of the paragraphs in s 73(5) express a power. Paragraphs (a) and (b) express obligations, although imperfect obligations to the extent that there is no means of enforcement. It is difficult to see how failure to act as quickly as is practicable could affect the validity of the Tribunal's decision-making, and para (a) is essentially aspirational; para (b) could more readily bear upon the validity of the Tribunal's decision-making.
49Ms Chand complained, referring to s 73(5)(b), that the Tribunal had not ensured that there was disclosed to it all material relevant to determining whether the work involved in dealing with the application for access to the documents would, if carried out, substantially and unreasonably divert RailCorp's resources away from their use by RailCorp in the exercise of its functions. I will hereafter use the shorthand "unreasonable diversion" and cognate expressions to refer to this exemption in s 25(1)(a1) of the FOI Act.
50What it was said the Tribunal should have done was not particularly clear. Ms Chand often spoke of a duty to enquire, and variously submitted that the Tribunal should have looked at the TRIM printouts (or perhaps she meant at the documents to which they referred) and seen that documents were duplicated and not all documents in fact related to her; that the Tribunal should have inquired into what the documents were that RailCorp was not releasing; and that the Tribunal should have enquired into "what was the exempt document and why they were not being released and why the FOI application was not being pressed". She said at one point that the Tribunal could have "directed RailCorp to give it a list of documents that it held with a brief description ... ". Ms Chand submitted to the effect that, had the Tribunal enquired, it would have recognised that Mr Morton's evidence of unreasonable diversion was exaggerated, and that the unreasonable diversion exemption was not made out. She drew attention to matters in the printouts and otherwise which she said should have "called up alarm bells" as to Mr Morton's exaggeration.
51Ms Chand's complaint extended to category 2 documents because, as best I understand it, she contended that a document in that category did exist and the Tribunal should have enquired into its existence and not accepted RailCorp's determination that it had no such document.
52Ms Chand described the Tribunal's failure to ensure that all relevant material was available as an error of law, or as jurisdictional error in misunderstanding or failing to exercise its power; she also said that there was want of good faith, and that there was procedural unfairness it seems because she was denied the assistance which would have come from the Tribunal exercising its power. Related to the Appeal Panel, the effect of the submissions was that there had been error on a question of law when it did not recognise error on a question of law by the Tribunal, but rather at [24]-[25] of its reasons rejected any obligation to "launch an enquiry into the agency's filing" and left to RailCorp what it should disclose. This complaint can be seen in grounds 1, 2, 3, 4, 5, 6 and 7 of the grounds of appeal, and possibly ground 8.
53Section 58 of the ADT Act, to which the Appeal Panel referred at [24], includes that the administrator whose decision is the subject of an application for review must lodge with the Tribunal copies of documents the administrator considers to be relevant to the determination of the application (s 58(1)(b)), and that the Tribunal may direct that the administrator lodge other documents as it considers relevant to the determination of the application (s 58(4)). By s 58(5), the Registrar of the Tribunal is to grant to the applicant reasonable access to any copy of a document lodged under the section by an administrator.
54Ground of appeal 1 was that the Appeal Panel was wrong in its reliance on s 58, when the application of s 58 was excluded by s 53(5) of the FOI Act. Section 53(5) provides that Division 2 of Pt 5 of the FOI Act, which is concerned with review by the Tribunal of an agency's determination of an application for access to a document or an application to amend its records, applies to an application for review of the determination "to the exclusion of ... Section 58 of the Administrative Decisions Tribunal Act 1997". It can readily be seen why the application of s 58 is excluded. It would defeat refusal to grant access to a document if the document had to be produced to the Tribunal and the applicant thereupon could have access to it.
55RailCorp accepted that the Appeal Panel had wrongly referred to s 58 of the ADT Act, but submitted that the erroneous reference was not material to its decision on what it called the procedural objection. That submission should be accepted.
56RailCorp had the burden of establishing that its determination was justified: ADT Act, s 61. It placed before the Tribunal the material on which it relied for that purpose, and Ms Chand placed material before the Tribunal in opposition and had the opportunity to challenge the extent of RailCorp's disclosure of material. Section 73(5)(b) does not speak of an enquiry, and for any obligation on the Tribunal to ensure that all relevant material was disclosed to be enlivened there had to be sound reason to conclude that all relevant material had not been disclosed.
57The Tribunal has no a priori knowledge of what all relevant material may be. The proceedings before the Tribunal were proceedings between parties (see in particular ADT Act, s 67), with presentation of the parties' cases (s 70; see also s 73(5)(c) and (d)). The Tribunal had powers to call witnesses and issues summonses for attendance and production of documents (ADT Act, ss 83, 84), and no doubt could have acted with a view to further material being disclosed in less compulsive ways, but before it could be said that it should act as required by s 73(5)(b) it had to appear to the Tribunal that there was relevant material to be disclosed so as to enable it to determine the facts in issue. Section 73(5)(b) did not require that the Tribunal act on speculation that there might be more material of relevance which RailCorp had not put before it, which would be likely to be a never-ending task.
58Ms Chand submitted that the Appeal Panel was in error in its reliance on Prasad v Minister for Immigration and Ethnic Affairs (1985) 6 FCR 155 and Minister for Immigration and Citizenship v SZIAI [2009] HCA 39; (2009) 259 ALR 429. The tentative remarks in the former case, in the context of Wednesbury unreasonable decision-making, were limited to enquiry into obviously available and centrally relevant material, with the observation that "[i]t is no part of the duty of the decision-maker to make the applicant's case for him": at 169-70. In the latter case the plurality contemplated possible jurisdictional error by a tribunal conducting inquisitorial proceedings if there were failure "to make an obvious enquiry about a critical fact, the existence of which is easily ascertained" (at [25]), but saw no occasion for further inquiry in that case; Heydon J said that it was "not unreasonable for the tribunal to proceed on the basis that if any further evidence was to be provided ... it would come from the respondent" (at [52]). Any obligation of a tribunal to inquire will depend on the nature of the tribunal and its powers and obligations. At the general level at which the Appeal Panel referred to these cases, there was no error, and s 73(5)(b) does not supply a more stringent obligation to enquire.
59At a factual level Ms Chand's complaint was, in part, one of failure to assess the material before the Tribunal adequately, not failure to require the disclosure of further material. So far as she contended that the Tribunal had not sufficiently examined the material before it, for example for duplications, any error was of fact. The Appeal Panel did not misunderstand the Tribunal's jurisdiction as relevantly found in s 73(5)(b). In its view, there was nothing unusual or apparently deficient in RailCorp's "filing" (para [25]), meaning the evidence on which was founded Mr Morton's explanation of why there would be substantial and unreasonable diversion, and it noted that Ms Chand "did not specify what she considered the shortcomings to be". It considered that there was no occasion for the Tribunal to have required disclosure of further material. This also was a question of fact. In my opinion, the Appeal Panel did not err on a question of law.
