Contextualising the issue
31 The question of whether the reasons for the decision of decision-maker (or the Tribunal in its stead) disclose the existence of a jurisdictional error, will seldom appear from a single sentence, let alone a part of a sentence. The impugned part of the reasons must be considered in the context of the whole.
32 As might appear from the above discussion of the Tribunal's reasons, the context of the issue before it was as follows:
(a) The applicant had sought a protection visa under s 65 of the Migration Act.
(b) An issue for consideration was whether Australia had protection obligations to him under the Refugee Criterion or other "complementary protection grounds".
(c) The applicant raised a number of issues in support of the assertion that he was vulnerable to persecution were he to be returned to Vietnam. They included his religion, claimed political activity, and his opposition to serving in the military. He also claimed that he would suffer persecution were he to be returned as a failed asylum seeker.
(d) The Tribunal considered a variety of reports of Country Information including a DFAT report, a report from the USDOS and a report from the UKHO. Whilst the Tribunal noted that dissident political opinion was supressed by persecution, the DFAT report expressly considered that whilst Vietnamese nationals who are failed asylum seekers and who are returned home might be detained briefly for interview, they are treated as victims of people smugglers. The USDOS and the UKHO reports were identified as corroborating the position stated by DFAT.
(e) There was no material before the Tribunal and none referred to in its reasons which suggested that failed asylum seekers or illegal departees were detained for extended periods on their return to Vietnam. To the extent that there was evidence on this topic it was that which was contained in the DFAT Country Information Report.
(f) Overall, the conclusion reached by the Tribunal was that if the applicant were returned to Vietnam he will be detained and questioned in order to establish his identity and to allow for his registration and he will be questioned about his illegal departure and the organisers of the boat trip. He will be prosecuted for his illegal departure from Vietnam. The Tribunal did not accept that these procedures will result in a real chance of serious harm to the applicant.
33 It is not inappropriate to observe that this is not a case where it is alleged that the Tribunal overlooked some evidence contained in the reports from the USDOS or from the UKHO which contradicted or was contrary to that in the DFAT report. It is also not a case where the Country Information from those sources suggested that failed asylum seekers would be detained for extended periods on their return to Vietnam. The complaint is that the last part of the last sentence of paragraph 73 incorrectly identified that the USDOS and UKHO reports verified the content of the DFAT report as to the treatment of failed asylum seekers in Vietnam. It is not submitted that the substance of the comment, being that failed asylum seekers are not detained for extended periods, was not in accordance with the evidence before the Tribunal.
34 The nature and extent of the alleged error can be tested in a couple of ways. First, it is useful to hypothesise what the position would be if the last part of the last sentence of paragraph 73 had not been included. If that were the case, such that the Tribunal did not believe that the identified reports corroborated the DFAT reports, it is extremely unlikely that the Tribunal would have reached a different conclusion. It had considered at length the content of the DFAT report on which it obviously placed considerable weight. In particular, it accepted the evidence in the DFAT report to the effect that returned failed asylum seekers and illegal departees are not detained for any extended period by the authorities in Vietnam on their return. That being so, and there being no evidence to the contrary, it follows that even if the Tribunal had not mistakenly believed that the other reports verified the DFAT report in this respect, it would inevitably have reached the same conclusion.
35 The matter can also be tested by considering the converse of that which is alleged to be in error. That is, what would be the position were the Tribunal to have concluded that failed asylum seekers or others who departed Vietnam illegally would be detained on their return (for a period longer than to enable the authorities to check their credentials). Such a determination would not withstand scrutiny. There was simply no information before the Tribunal which suggested that to be the case. The evidence about this topic was contained in the DFAT report which refuted such a proposition. Further, the USDOS and the UKHO reports inferentially supported the DFAT report by indicating that "political activists" and others were detained but they did not suggest that failed asylum seekers or illegal departees were treated in that manner.
36 It is also relevant to keep steadily in mind that the alleged error or finding as to the content of the UK and USA Country Information was a finding which occurred "on the way, to the intermediate conclusion that the applicant, as a failed asylum seeker who departed Vietnam illegally would not be the subject of persecution on his return". That conclusion was, of itself, a step in the process of determining that the applicant was not a person in respect of whom Australia owed convention responsibility.
37 It would appear that a jurisdictional error might arise as a result of an illogical, irrational or unreasonable finding of fact which is "on the way" to a final conclusion (see Minister for Immigration and Citizenship v SZMDS (2010) 240 CLR 611 at 648, [131]-[132]; Minister for Immigration and Citizenship v SZRKT (2013) 212 FCR 99 at 137-138, [151]-[153]; SZWCO v Minister for Immigration and Border Protection [2016] FCA 51 at [61]-[62]; CQG15 v Minister for Immigration and Border Protection (2016) 70 AAR 413 at 434-435, [60]). However, such errors of fact will be within the jurisdiction of the Tribunal to make if they are not critical to, or are immaterial to the final outcome. This point was made by Wigney J in Minister for Immigration and Border Protection v SZUXN (2016) 69 AAR 210 where his Honour said:
55. Nevertheless, allegations of illogical or irrational reasoning or findings of fact must be considered against the framework of the inquiry being whether or not there has been jurisdictional error on the part of the Tribunal: SZRKT at 137 [148]. The overarching question is whether the Tribunal's decision was affected by jurisdictional error: SZRKT at 137-138 [151]. Even if an aspect of reasoning, or a particular factual finding, is shown to be irrational or illogical, jurisdictional error will generally not be established if that reasoning or finding of fact was immaterial, or not critical to, the ultimate conclusion or end result: Minister for Immigration and Citizenship v SZOCT (2010) 189 FCR 577 at 598-599 [83]-[84] (Nicholas J); SZNKO v Minister for Immigration and Citizenship [2013] FCA 123 at [113]. Where the impugned finding is but one of a number of findings that independently may have led to the Tribunal's ultimate conclusion, jurisdictional error will generally not be made out: SZRLQ v Minister for Immigration and Citizenship (2013) 135 ALD 276 at 291 [66]; SZWCO at [64]-[67].
This paragraph was cited with approval by the Full Court of this Court in CQG15 v Minister for Immigration and Border Protection at 434, [60].
38 Here the alleged erroneous view of the Country Information in the USDOS and UKHO reports cannot be said to be "critical to" the ultimate conclusion which was reached. As is apparent from paragraph 73 and its context, those reports were merely relied upon to confirm that which the Tribunal had identified existed in the DFAT reports. They were used as corroborating evidence.
39 As identified in paragraphs 99 and 100, which are set out above and which form part of the Tribunal's "FINDINGS AND REASONS", the Tribunal accepted the DFAT Country Information that the applicant would only be subject to a small fine when he was returned as a consequence of him having left Vietnam illegally. The Tribunal also relied upon the DFAT information to find that the applicant will be regarded as a victim of people smuggling operations and as such he would be detained for a brief period to establish his identity and to renew his registration. That information also led it to the conclusion there is no evidence to suggest that he will be treated differently because he sought asylum in Australia. DFAT had also advised that persons were detained for an extended period only where they were regarded as political activists. It follows that there was substantial material before the Tribunal on which it was able to base its findings that the applicant, as a failed asylum seeker and one who departed Vietnam illegally, would be detained briefly for checking and registration purposes and would also incur a small fine. There being no evidence of the applicant being involved in political activities, there was no real chance of serious harm to him on his return.
40 The Tribunal was easily able to reach the conclusion which it did based on the DFAT Country Information report. It had accepted the content of that report and relied on it in all other respects. Moreover, there existed no other evidence to the contrary.
41 Additionally, to the extent to which the statement in paragraph 73 (and paragraph 101) was in error, it was only in relation to what was stated in the UKHO and USDOS reports. On the material before the Tribunal, the substance of the comment, namely that failed asylum seekers and others who departed illegally would not be detained for extended periods, was not erroneous. Indeed, it was consistent with all of the information before the Tribunal. It follows that the impugned comment could not have had any real bearing on the decision process.
42 Finally, there was no evidence that failed asylum seekers or persons who had departed Vietnam illegally would be detained for extended periods. Any finding to that effect would have been contrary to the only material before the Tribunal on that topic.
43 It follows that the reliance on the alleged erroneous statement as founding a jurisdictional error has no chance of supporting any argument as to the existence of a jurisdictional error.
