The arguments on appeal
13 Counsel for the appellant subjected the expression of the reasons of the Tribunal to logical, indeed philosophical, analysis in an effort to show that those facts which, as the learned trial judge accepted, might otherwise have been impugned within the meaning of ss 476(1)(g) and 476(4)(b) were among reasons "conjunctively" as distinct from "disjunctively" relied upon by the Tribunal. The purpose of this was to found a submission that, as the Tribunal had relied on all of the found facts referred to above, including those sought to be impugned, the decision must be regarded as in part "based on" the variously impugned facts.
14 Counsel relied on the well-known passage in Curragh v Queensland Mining Co (1997) 34 FCR 212 at 220-1:
"Section 5(3)(b) does not require the identification of some single particular fact that may be said to be the foundation of the decision. A decision may be based upon the existence of many particular facts; it will be based upon the existence of each particular fact that is critical to the making of the decision. A small factual link in a chain of reasoning, if it is truly a link in a chain and there are no parallel links, may be just as critical to the decision, and just as much a fact upon which the decision is based, as a fact that is of more obvious immediate importance. A decision may also be based on a finding of fact that, critically, leads the decision-maker to take one path in the process of reasoning rather than another and so to come to a different conclusion.
If a decision is in truth based, in the sense I have described, on a particular fact for which there is no evidence, and the fact does not exist, the decision is flawed whatever the relative importance of the fact. Accordingly, I agree with the conclusion of Lee J in Akers v Minister for Immigration and Ethic Affairs (1988) 20 FCR 363 at 374, that there is no reason to read s.5(3)(b) in a way that would limit its operation to a predominant reason for the decision under review."
Counsel further relied on the following passage from Minister for Immigration & Multicultural Affairs v Rajamanikkam [2000] FCA 1023 (Full Court) at [49]:
"Thus it was the combination of factors which caused the Tribunal to doubt the respondent's claims. It was the accumulation of difficulties with his evidence which led to its conclusion. Each of those two facts which have been shown not to exist was integral to a factor which comprised part of that accumulation. Neither of those two matters is therefore of peripheral importance to the decision. As the Tribunal has described its process of reasoning, each is a matter which played a part in the Tribunal's process of reasoning. That is so, not simply taking those two matters separately, but also because they contributed to its conclusions concerning factor (3). This is not, therefore, a case where those matters are merely parallel links in a chain of reasoning; they are matters without which the Tribunal may well not have reached the conclusion which it did. In our judgment, each of those matters in the particular circumstances of this case were particular facts upon which the Tribunal based its decision to reject the respondent's primary claims as concocted. As those facts were facts which did not exist, the ground of review under s 476(1)(g) and (4)(b) has been made out.' "
15 Counsel also made particular submissions about the supposed dependence of the finding that the appellant would have required documentation to run a shop in China on the applicability of the hukou system to the appellant. The learned trial judge may have entertained some doubt as to such applicability. As that matter, indeed the second ground of appeal generally, is but a particular instance of the more general point asserted by the first ground of appeal, we think that, in the light of our conclusions as to the first ground, we need not address it further.
16 For the respondent, counsel reminded the Court of the strictures in Wu Shan Liang v Minister for Immigration & Multicultural Affairs (1996) 185 CLR 259 at 291 per Kirby J and other cases against overzealous scrutiny of the language used by an administrative tribunal such as the Tribunal and that these cautions should be applied to the structure of the reasons as much as to the language used: see Kaur v Minister for Immigration & Multicultural Affairs [2001] FCA 1401 at [15] per Moore J. In general, counsel argued that none of the asserted facts which were sought to be impugned, either alone or taken together, could be said to be critical as to the reasoning of the Tribunal within the approach taken in Curragh, nor did they "depend on" asserted facts (language used in Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 at 340-1. Rather, it was submitted, each fact was, and together they were, "but one of many factors that led the Tribunal to its conclusion": the formulation in Minister for Immigration & Multicultural Affairs v Indatissa [2001] FCA 181 at para 35. Further, the Tribunal's finding that the appellant was not a credible witness was indeed based, as Marshall J said, "on a number of particular facts which did exist, independently of each other" with the result that the case was factually distinguishable from Rajamanikkam.
Consideration
17 Logical and even elegant as the appellant's effort was to show that the Tribunal regarded every fact to the discredit of the appellant as integral or critical to its decision, we think that the submission substitutes emphasis on the form of the decision for what is required, namely, a real and genuine attempt to understand what the Tribunal member was intending to convey.
18 Reading the decision as a whole, it is satisfactorily clear in our view that the Tribunal member relied on a good many matters, including some of evident substance, in addition to the impugned findings, to disbelieve the appellant's claim that he would be at risk of persecution for having clandestinely subverted China's emigration laws for political purposes.
19 Doubts may possibly arise as to the correct interpretation of, and interrelationship between subs (1)(g) and (4)(b) of s 476 of the Act. The orthodox view, relying on what was said by Mason CJ in Bond at 357-9 as to the analogues of these paragraphs in the Administrative Decisions Judicial Review Act 1977 (Cth), is that subs (4) and in particular subs (4)(b) enlarges what might otherwise have been thought to be a mere restatement of the common law by subs (1)(g). It need not now be considered to finality whether that view is correct or is able to be challenged in this Court. For present purposes, it may be assumed that the orthodox view is correct. Furthermore, it is assumed, though it is doubtful, that the "decision" identified in the Notice of Appeal and in the Application for Judicial Review, might be as set out at para 6 above. It may also be assumed that the asserted facts, alone or together, might qualify as the kind of "fact" with which s 476(4)(b) is concerned.
