CONSIDERATION
30 With one exception which I will come to below, I do not consider the primary judge erred in the conclusions outlined above on the two issues raised by this appeal. On the first issue, concerning the order in which the Tribunal considered the three documents, provided that it proceeded according to the precepts of reasonableness and considered any cogent evidence presented by the first appellant and his clearly articulated claims, it was open to it to conduct the review in the order it considered appropriate (see Re Minister for Immigration and Multicultural Affairs; Ex parte Applicant S20/2002 (2003) 198 ALR 59; [2003] HCA 30 (S20/2002) at [14] and Minister for Immigration and Citizenship v SZNSP (2010) 184 FCR 485; [2010] FCAFC 50 at [33]). Thus, it could, as it did (at [18]-[24], summarised at [15]-[20] above), first consider the appellant's claims and evidence about the September 1991 incident and determine whether it thought they were credible. There is, in my view, no error in adopting that approach.
31 Having done so, again subject to the same constraints, it was also open to it to proceed (as it did at [25]-[27], summarised at [22]-[25] above), to assess the relevance of, and weight to be given to, the three documents. In that exercise, as Gleeson CJ observed in S20/2002 (at [12]):
… It is not necessarily irrational, or illogical, for a finder of fact, who is convinced that a principal witness is fabricating a story, which is considered to be inherently implausible, to reject corroborative evidence, even though there is no separate or independent ground for its rejection, apart from the reasons given for disbelieving the principal witness.
32 However, in this matter, the Tribunal did not even go that far. That is to say, instead of rejecting the three documents outright, it said "I have given them no weight" (at [27], see at [24] above). Furthermore, instead of just relying on its anterior adverse credibility findings in respect of the appellant, it provided three additional reasons (but see further at [33] below) why it decided to proceed in that manner (see at [27] of the Tribunal's reasons). Hence, I do not consider the Tribunal committed any error in the manner in which it dealt with the three documents.
33 Two further matters remain to be mentioned. Both involve errors, one by the primary judge and the other by the Tribunal. However, neither of them affects the validity of my conclusions above. That is to say, the first is not sufficiently significant that it adversely affects the overall correctness of the conclusions reached by the primary judge as discussed above and the second does not reach the level of seriousness necessary to constitute jurisdictional error on the part of the Tribunal (see Minister for Immigration and Citizenship v SZRKT (2013) 212 FCR 99; [2013] FCA 317 at [111] and BHL19 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCAFC 94 at [145]). The first concerns the exception mentioned at the outset of this section (see [30] above). For the reasons already given above (at [32]), I do not consider the Tribunal went as far as "reject[ing] the veracity" of the three documents as the primary judge appears to have concluded at [76] of his reasons (see at [28] above; see also [91] of FOW17 at [29] above). The second concerns the second of the three reasons the Tribunal provided at [27] of its reasons for deciding to give the three documents no weight. In this appeal, it is common ground that the Tribunal erred in describing the first appellant as a "civilian" for the reasons provided by the primary judge at [80]-[82].
