The appeal to this Court
22 In his original notice of appeal, the appellant sought to rely upon essentially the same grounds as were raised before the primary judge. However, by notice filed on 21 May 2003, he sought leave to substitute amended grounds of appeal. There were three such grounds, but at the hearing of the appeal the appellant sought to rely upon two grounds only, namely:
"(2) That the Learned Judge erred in law in finding that the Tribunal had considered, as it was required to do so, a significant integer of the Appellants claim, namely the cumulative effect of the claims on whether the Appellants fear was well founded contrary to the then s 476(1)(e) of the Migration Act.
(3) That the Learned Judge erred in finding that the failure of the Tribunal to address the issue of the imputed political belief was not of itself a sufficient failure to amount to a failure to exercise the Tribunal's jurisdiction contrary to the then s 476(1)(e) of the Migration Act."
23 It was submitted, on behalf of the appellant, that the primary judge erred by concluding that the Tribunal had not made reviewable errors, under the general law, of the type identified in Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 at 351. It was further submitted that the Tribunal failed to consider, as it was required to do, a number of significant "integers" of his claim: Htun v Minister for Immigration and Multicultural Affairs (2001) 194 ALR 244. Finally, it was submitted that the Tribunal failed to consider his claims cumulatively.
24 It was conceded that these submissions were all based upon a single passage in the primary judge's reasons for judgment. That passage related to the Tribunal's non-acceptance of the appellant's claim that, by reason of his involvement in the demonstration in the neighbouring town, he would have imputed to him a political opinion, namely, "support for the Mojahedin" [sic]. The passage reads:
"However, if the demonstration was, as the applicant claimed, by supporters of the Mujahedeen, it is difficult to see why the Tribunal did not accept that the applicant, as a participant in the demonstration, might not be imputed with an opinion in support of the Mujahedeen. It said that country information indicates a 'lack of support' for that group within Iran. That does not mean there is no support for it, or that the demonstration was not in support of it. The lack of general support for that group in Iran does not mean, as the Tribunal seemed to conclude, that the applicant attending a demonstration (the purpose of which the Tribunal has made no finding about) might not lead to the applicant being imputed with an anti-regime political opinion.
…
At the level of an individual finding, any deficiency in the Tribunal's reasoning process does not lead to the conclusion of reviewable error on its part for the reasons already given. I do not therefore consider this discrete attack upon the Tribunal's decision can succeed."
25 It was submitted, on behalf of the appellant, that the primary judge erred in concluding that the deficiency in the Tribunal's reasoning process to which he referred did not amount to reviewable error. That submission was based upon the premise that his Honour's finding amounted to a conclusion that the Tribunal failed to deal with one of the appellant's claims, and thereby erred in law in a manner that gave rise to review under s 476(1)(e).
26 His Honour's error was said to be compounded by his failure to recognise that this meant that the Tribunal had committed a second error of law. That second error was said to be his failure to deal with the appellant's claims against the background of a finding that he may face persecution by reason of imputed political opinion. The imputation would arise because there would be a perception that, by reason of his involvement in the demonstration, he was a supporter of the Mujahadeen.
27 In addition, there was said to be a third error of law. It was submitted that the primary judge ought to have concluded that the Tribunal did not deal with the appellant's claims cumulatively. The reason it did not do so was because it failed to appreciate the importance of the risk that there would be imputed to the appellant an allegiance to the Mujahadeen. If that risk was real, it would have an impact upon each of the other "integers" of the appellant's claim. It would follow that some aspects of that claim, not of themselves sufficient to give rise to a well-founded fear of persecution, would be viewed in a different, and significantly more cogent, light.
28 In response to these submissions, the respondent contended that the primary judge identified a deficiency in the Tribunal's reasoning process, but correctly concluded that it did not give rise to any reviewable error. It was submitted that there was no reviewable error for two separate reasons.
29 The first was that his Honour had taken an unduly generous view of the width of the appellant's claim before the Tribunal when he described that claim as one of "imputed political opinion relating to perceived links with the Mujahedeen". In truth, the appellant had barely mentioned the Mujahadeen, and made no claim based upon any imputed political opinion arising out of his involvement in the demonstration. Rather, the claim based upon imputed political opinion centred on the role played by his father during the regime of the Shah, and to a lesser degree upon his claim to have had a significant role in organising the demonstration (a claim which the Tribunal rejected).
30 The second reason for submitting that the primary judge did not fall into error in rejecting the claim that there was reviewable error upon the part of the Tribunal was more fundamental. It was submitted that his Honour essentially concluded that the particular passage in the Tribunal's reasons which he criticised contained illogical, or untenable, reasoning, but this did not give rise to reviewable error. In particular, it did not amount to an error of law within s 476(1)(e): Minister for Immigration and Multicultural Affairs v Rajalingam (1999) 93 FCR 220.
