Third ground of appeal
33 The third ground of appeal seeks to agitate the proposed ground of review that was the subject of a leave to amend application before the primary judge. By that ground, the appellant contends that the Authority's rejection of his claims about threatening phone calls was illogical and irrational, or alternatively the rejection of those claims gives rise to an apprehension of bias.
34 The decision of the primary judge to refuse leave to amend was a discretionary decision made under r 7.01 of the then Federal Circuit Court Rules 2001 (Cth). There appears to be some disagreement in the authorities whether the decision should be characterised as interlocutory or final for the purposes of s 24(1A) of the Federal Court of Australia Act 1976 (Cth). In BXU16 v Minister for Immigration and Border Protection [2018] FCA 1897, Lee J concluded that such a decision was interlocutory in nature, requiring leave to appeal (at [2]). However, in CWX18 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2020] FCA 673, Gleeson J concluded that, if the refusal of leave to amend results in the dismissal of the application to review, the refusal finally disposes of the rights in the proceeding and is therefore final in nature (at [17]-[19]). In the present case, the Minister took no point that the appellant required leave to appeal on this ground. In the circumstances, and in the absence of argument, it is unnecessary to determine that question and I will proceed on the basis that, if leave is required, it is not opposed.
35 However, as the refusal of leave to amend is a discretionary decision, the appellant is required to demonstrate an error in the exercise of that discretion in accordance with the principles explained in House v The King (1936) 55 CLR 499 (House v King) at 505. It is not apparent from the primary judge's reasons that, in refusing leave to amend, his Honour acted upon a wrong principle, or allowed extraneous or irrelevant matters to guide or affect his decision, was mistaken as to the facts or failed to take into account some material consideration. As noted earlier, in refusing leave to amend, the primary judge took into account the potential prejudice to the Minister, any explanation for the delay in bringing forward the amendment and the merits of the ground. All are relevant considerations (although delay in seeking the amendment may have little significance in migration matters where it may be inferred that the applicant has limited funding for or access to legal assistance and where no prejudice to the opposing party or inconvenience to the court is caused). Nevertheless, as error may also be inferred from the result (the refusal for lack of merit), it is necessary to consider the primary judge's assessment of the merits of the ground.
36 The finding of the Authority that is challenged is the rejection of the appellant's claim to have received three threatening phone calls. Ultimately, the Authority concluded that the claim lacked credibility because the appellant had failed to make the claim in his entry interview, but the claim became a central aspect of his TPV application.
37 Credibility findings are not immune from judicial review, but to establish jurisdictional error it is ordinarily necessary to show that the findings were legally unreasonable, for example by being based on illogical or irrational findings or inferences of fact: Minister for Immigration v Eshetu (1999) 197 CLR 611 at 626 per Gleeson CJ and McHugh J and at 657 per Gummow J; Minister for Immigration and Multicultural Affairs; ex parte Applicant S20/2002 (2003) 73 ALD 1 at [5] per Gleeson CJ; Minister for Immigration and Multicultural and Indigenous Affairs v SGLB (2004) 78 ALD 224 at [37]-[38] per Gummow and Hayne JJ. However, judicial review does not involve mere merits review - it is not enough for the question of fact to be one on which reasonable minds may differ: Minister for Immigration and Citizenship v SZMDS (2010) 240 CLR 611 at [96] and [130] per Crennan and Bell JJ; ARG15 v Minister for Immigration and Border Protection (2016) 250 FCR 109 at [47].
38 The principles which guide judicial review of findings concerning credibility have been discussed by the Full Federal Court in a number of recent decisions, including CQG15 v Minister for Immigration and Border Protection (2016) 253 FCR 496 at [59]-[60]; DAO16 v Minister for Immigration and Border Protection (2018) 258 FCR 175 at [30]; AVQ15 v Minister for Immigration and Border Protection (2018) 266 FCR 83 (AVQ15) at [41]. Those principles include the following:
(a) Whether or not a credibility finding is affected by jurisdictional error is a case specific enquiry and should not be assessed by reference to fixed categories or formulae.
(b) Even if an aspect of reasoning, or a particular finding of fact, is shown to be irrational or illogical, jurisdictional error will generally not be established if that reason or finding of fact was immaterial, or not critical, to the ultimate conclusion or end result (such as, for example, where it is by one of several findings that independently may have led to the ultimate decision).
(c) Considerable caution must be exercised before concluding that errors in an adverse credibility assessment result in the decision being affected by jurisdictional error, in order to avoid judicial review transgressing into the impermissible area of merits review.
39 The Court has explained on many occasions why differences, or even inconsistencies, in claims made over time by persons seeking asylum must be assessed fairly and reasonably and without a presumption that the person has been dishonest in respect of the claims. In W375/01A v Minister for Immigration and Multicultural Affairs (2002) 67 ALD 757 the Court observed (at [15]):
As anyone with even a passing familiarity with litigation will know, to have to give a decision-maker three or more separate versions of the basis for a claim is an invidious position to find oneself in, even in the case of an honest witness. All the more so when the accounts have been provided by a person who speaks no English and who has required the assistance of an interpreter. It is inevitable that each version will be slightly different, and may even be very different once the impact of the interpreter is taken into account.
40 In AVQ15, the Full Court explained (at [23], [27]-[28]):
23 A decision-maker is entitled to rely upon inconsistencies in assessing a visa applicant's credibility but it is important that the process be conducted fairly and reasonably, taking into account that the assessment of the reliability, and credibility, of accounts given by asylum seekers is well recognised as involving a number of particular features and considerations, and calls for a careful and thoughtful approach.
…
27 Secondly, the term "inconsistency" should be used with appropriate caution and an appreciation of the danger of using labels or formulae which mask the need for deeper analysis. As we have noted above, adverse credibility findings might be based on a variety of matters, including inconsistencies between, for example, evidence or claims made at different stages of the decision-making process or differences between oral evidence and contemporaneous documents. In some circumstances a visa applicant may raise a claim for the first time at an advanced stage of the decision-making process and the failure to raise the claim previously may well be relevant to credibility, but that is not to say that this is correctly described as an inconsistency.
28 Thirdly, even where it is reasonably open to find that a person has given inconsistent evidence, the decision-maker needs to assess the significance of that inconsistency and the weight to be given to it. This requires consideration of, for example, the significance of the inconsistency having regard to the person's case as a whole and whether the inconsistency is on a matter which is central to the person's case or is at its periphery and involves an objectively minor matter of fact. It also requires the decision-maker to remain conscious of the particular challenges facing asylum seekers in giving accounts of why they fear persecution, including that they may have to give multiple accounts, using interpreters, and that they may reasonably expect an interview or a review process will provide an opportunity for them to elaborate on, or explain, the narratives they have previously given. Consideration should also be given to whether there is an acceptable explanation for the person having given inconsistent evidence such that the fact of the inconsistency should attract little, if any, weight. How all these matters are weighed and evaluated in a particular case is a matter for the decision-maker, but a failure by the decision-maker to appreciate the particular nature of the task, or to perform it reasonably and fairly, may be the subject of judicial review.
41 In the present case, I do not discern any error in the primary judge's assessment of the overall merits of this ground of review. The reasons of the Authority, reproduced earlier, demonstrate careful consideration of the differences in the appellant's claims to fear harm over time. At reasons [27], the Authority noted that the appellant's evidence regarding the threatening telephone calls he claims to have received has varied. The choice of the word "varied" is significant. The Authority demonstrated an awareness that the appellant's evidence was not inconsistent (see reasons [31]), but did vary. At reasons [32], the Authority identified the concern that the appellant had failed to refer to the phone calls in any way during his entry interview, and yet in the TPV interview the calls were identified as the central reason for his departure from Pakistan. The Authority gave consideration to whether there was an explanation for this difference, and first considered the manner in which the entry interview had been conducted (see reasons [31]-[33]). Next, the Authority considered the appellant's explanation for the difference (see reasons [34]).
42 Minds may differ about the Authority's overall assessment of the credibility of the appellant's claims concerning the threatening phone calls. A reasonable assessment of the overall circumstances might have been that the appellant did not appreciate, at the time of the entry interview, the level of detail or specificity about incidents of harm being sought by the interviewer, and only provided greater specificity in the context of a later, more thorough, interview process. However, that does not render the Authority's assessment irrational or legally unreasonable. In my view, the finding made by the Authority was open to it.
43 In those circumstances, there is no basis on which to conclude that the decision of the primary judge, refusing leave to amend, was affected by House v King error. Accordingly, appeal ground three must be rejected.
