Legal framework
13 The power in r 44.12(1)(a) to dismiss the appellant's application required a lack of satisfaction on the part of the FCCA judge that the appellant had raised an arguable case for the relief claimed, and the exercise of discretion: SZTTW v Minister for Immigration and Border Protection [2014] FCA 837 at [20]; Siddique v Minister for Immigration & Border Protection [2014] FCA 1352 at [19]-[21].
14 The principal issue in this Court is whether the FCCA judge erred in failing to be satisfied as to the existence of an arguable case that the IAA's decision involved jurisdictional error. In SZTGS v Minister for Immigration and Border Protection [2014] FCA 676 at [23] and [24], I noted:
[23] In other contexts, an appeal against a finding of satisfaction as to a matter is subject to the same principles that apply to an appeal from a discretionary decision: see Singer v Berghouse (1994) 181 CLR 201 especially at 210-212; Coal and Allied Operations Pty Ltd v Australian Industrial Relations Commission (2000) 203 CLR 194 especially at [19], [27], [32] and Russo v Aiello (2003) 215 CLR 643 at [27].
[24] Applying these principles in this case, the applicant must demonstrate sufficient doubt that, in failing to be satisfied that the application had raised an arguable case for relief, the primary judge:
a. Acted upon a wrong principle;
b. Allowed extraneous or irrelevant matters to guide or affect him;
c. Mistook the facts;
d. Did not take into account some material consideration; or
e. Reached a result that is plainly unreasonable or unjust: House v R (1936) 55 CLR 499 at 504-505.
15 The grounds of appeal mirror grounds of review raised in the FCCA. Each ground of appeal is expressed as a failure on the part of the FCCA judge to find error on the part of the IAA. The alleged errors are factual errors concerning aspects of the appellant's claims for protection. The appellant contended that the IAA's errors demonstrate that the IAA "declined its jurisdiction" and that, when considered separately or cumulatively, the errors reveal jurisdictional error on the part of the IAA. In respect of most grounds of appeal, the appellant's contention was to the effect that the IAA had either mistaken the facts or reached a result that was plainly unreasonable.
16 As to what would constitute jurisdictional error by the IAA, in Minister for Immigration and Multicultural Affairs v Yusuf [2001] HCA 30; 206 CLR 323, McHugh, Gummow and Hayne JJ said at [82]:
It is necessary, however, to understand what is meant by "jurisdictional error" under the general law and the consequences that follow from a decision-maker making such an error. As was said in Craig v South Australia [1995] HCA 58; (1995) 184 CLR 163 if an administrative tribunal (like the Tribunal):
"falls into an error of law which causes it to identify a wrong issue, to ask itself a wrong question, to ignore relevant material, to rely on irrelevant material or, at least in some circumstances, to make an erroneous finding or to reach a mistaken conclusion, and the tribunal's exercise or purported exercise of power is thereby affected, it exceeds its authority or powers. Such an error of law is jurisdictional error which will invalidate any order or decision of the tribunal which reflects it".
"Jurisdictional error" can thus be seen to embrace a number of different kinds of error, the list of which, in the passage cited from Craig, is not exhaustive. Those different kinds of error may well overlap. The circumstances of a particular case may permit more than one characterisation of the error identified, for example, as the decision-maker both asking the wrong question and ignoring relevant material. What is important, however, is that identifying a wrong issue, asking a wrong question, ignoring relevant material or relying on irrelevant material in a way that affects the exercise of power is to make an error of law. Further, doing so results in the decision-maker exceeding the authority or powers given by the relevant statute. In other words, if an error of those types is made, the decision-maker did not have authority to make the decision that was made; he or she did not have jurisdiction to make it. Nothing in the Act suggests that the Tribunal is given authority to authoritatively determine questions of law or to make a decision otherwise than in accordance with the law.

17 Jurisdictional error "is an expression not simply of the existence of an error but of the gravity of that error": Hossain v Minister for Immigration and Border Protection [2018] HCA 34; 264 CLR 123 (Hossain) at [25] (Kiefel CJ, Gageler and Keane JJ).
18 In CQG15 v Minister for Immigration and Border Protection [2016] FCAFC 146; 253 FCR 496 at [59]-[61], the Full Court explained the principles concerning a finding of illogicality, irrationality or unreasonableness in fact finding as follows:
[59] One of the difficulties in the appellant's argument is the conclusion reached by the High Court in Minister for Immigration and Citizenship v SZMDS [2010] HCA 16; 240 CLR 611, particularly (at [131]), where Crennan and Bell JJ stated that if reasonable minds could differ as to the conclusions to be drawn from the evidence, illogicality or irrationality or unreasonableness could not arise simply because one conclusion had been preferred to another possible conclusion.
[60] In Minister for Immigration and Border Protection v SZUXN [2016] FCA 516, Wigney J collected the following relevant principles (at [52] and [54]-[56]):
[52] As Robertson J put it in Minister for Immigration and Citizenship v SZRKT [2013] FCA 317; (2013) 212 FCR 99 at 137 [148], for a decision to be vitiated for jurisdictional error based on illogical or irrational findings of fact or reasoning, "extreme" illogicality or irrationality must be shown, "measured against the standard that it is not enough for the question of fact to be one on which reasonable minds may come to different conclusions". And as McKerracher J (with whom Reeves J agreed) emphasised in SZOOR v Minister for Immigration & Citizenship [2012] FCAFC 58; (2012) 202 FCR 1 (at 22-23 [84]), a decision cannot be said by a reviewing court to be illogical, irrational or unreasonable simply because one conclusion has been preferred to another possible conclusion.
...
[54] ... The judgment of Crennan and Bell JJ in SZMDS reveals that jurisdictional error may be able to be established on the basis of illogical reasoning or illogical or irrational findings "on the way" to the final conclusion (see 648 [132]): see also SZRKT at 137-138 [151]-[153]; SZWCO v Minister for Immigration and Border Protection [2016] FCA 51 at [61]-[62].
[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 [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] FCAFC 159; (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] FCA 566; (2013) 135 ALD 276 at 291 [66]; SZWCO at [64]-[67].
[56] An irrational or illogical finding, or irrational or illogical reasoning leading to a finding, by the Tribunal that the review applicant was not a credible or honest witness may in some circumstances lead to a finding of jurisdictional error. That would particularly be the case where the adverse credibility finding was critical to the Tribunal's decision that it was not satisfied that the applicant met the criteria for the grant of a visa. Whilst it is frequently said that findings as to credit are entirely matters for the Tribunal, such findings do not shield the Tribunal's decision-making processes from scrutiny: SZSHV v Minister for Immigration and Border Protection [2014] FCA 253 at [31]. Considerable caution must, however, be exercised before too readily acceding to a proposition that adverse findings as to credit expose jurisdictional error: SZVAP v Minister for Immigration and Border Protection [2015] FCA 1089; (2015) 233 FCR 451 at 455-456 [14]- [15]. That is because assertions of illogicality and irrationality can all too readily be used to conceal what is in truth simply an attack on the merits of the Tribunal's findings and decision. In SZMDS, Crennan and Bell JJ (at 636 [96]) made it plain that the deployment of illogicality or irrationality to achieve merits review should not be sanctioned.
[61] For present purposes, there is a difficulty for the appellant in demonstrating "extreme" illogicality. Even emphatic disagreement with the Tribunal's reasoning would not be sufficient to make out illogicality, according to SZMDS (at [124]). Although the appellant contends that the implausibility and inconsistencies were only "minor", his Honour disagreed (at [26]-[27]).
19 An error that could not have resulted in a different decision does not give rise to jurisdictional error: Hossain at [30]-[31]; AOJ18 v Minister for Home Affairs [2018] FCAFC 220 (AOJ18) at [32].
20 In considering whether an administrative decision maker's decision was the product of, or was materially affected by, illogical or irrational reasoning or factual findings, the decision maker's reasons should not be the subject of over-zealous scrutiny: BHL19 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCAFC 94 at [146], citing Minister for Immigration and Ethnic Affairs v Wu Shan Liang [1996] HCA 6; 185 CLR 259 at [272].
