Sections 476(1)(g) and 476(4)(b) and the applicant's associated submissions
23 Mr Bravender-Coyle submitted that the decision of the RRT was open to attack under the no-evidence ground found in ss476(1)(g) and 476(4)(b) of the Act. He contended that the decision of the RRT was based on a number of conclusions which, in turn, were based on a series of particular facts which did not exist. Accordingly, it was submitted by Mr Bravender-Coyle that the decision of the RRT not to grant Mr Choi a protection visa was based on "particular facts that did not exist": see s476(4)(b), ie. there was "no evidence or other material to justify the making of the decision"; see s476(1)(g).
24 The leading authority dealing with the expression "based the decision on the existence of a particular fact" is the judgment of a Full Court of this Court in Curragh. Whilst that case concerned ss5(1)(h) and 5(3)(b) of the Administrative Decisions (Judicial Review) Act 1977 (Cth), in Minister for Immigration & Multicultural Affairs v Rajamanikkam [2000] FCA 1023, a Full Court of this Court held (at [19]) that those provisions being analogous to ss476(1)(g) and 476(4)(b) of the Act respectively, the reasoning of the Court in Curragh concerning the meaning of the term "based the decision on the existence of a particular fact" is equally applicable to the meaning of that term as found in s476(4)(b) of the Act.
25 In Curragh, Black CJ (with whom Spender and Gummow JJ agreed) stated that (at 220 - 221):
"If the existence of a particular fact is seen to be critical to the making of a decision then the decision will be based on the existence of that particular fact.
…
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 (emphasis supplied), 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."
26 In Rajamanikkam, the Full Court relevantly stated (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 (emphasis supplied); 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 ss476(1)(g) and (4)(b) has been made out."
Thus, if it is shown that a particular fact found by the RRT to exist does not exist, and that fact was relied upon by the RRT to reach its decision, but, "there was nonetheless other evidence or material before the RRT to justify that decision", then the ground of review available under ss476(1)(g) and 476(4)(b) of the Act will not have been made out: see Li Yue at [54], per Hill, Matthews and Lindgren JJ.
27 Mr Bravender-Coyle submitted that the RRT based its decision on the evidence of a series of particular facts which did not exist being facts "without which the Tribunal may well not have reached the conclusion which it did". In particular, Mr Bravender-Coyle took issue with the RRT's finding that the first applicant "could not identify any of the office holders of the organisation". He submitted that an examination of the transcript of the hearing before the RRT shows that the evidence was that the applicant deposed that he did not know the President, or the name of the President, but he knew the name of its Secretary, a Miss Wong.
An examination of the relevant exchange in the transcript of the hearing before the RRT bears this out:
