Some relevant legal principles
50 The relevant legal principles relating to the question whether or not the Tribunal falls into jurisdictional error if it fails to deal with an element of an applicant's claim, were conveniently summarised by the Full Court in NABE at [55] and [63] (per Black CJ, French and Selway JJ):
Failure to Deal with a Claim - Express and Implied Claims
[55] Although the discussion in S20 did not set any precise limit upon the scope of factual error which may amount to or indicate jurisdictional error there is, in the case of Refugee Review Tribunal decisions, one circumstance in which it is clearly established that the absence of a finding of a relevant fact may amount to jurisdictional error. Where the Tribunal fails to make a finding on " … a substantial, clearly articulated argument relying upon established facts" that failure can amount to a failure to accord procedural fairness and a constructive failure to exercise jurisdiction - Dranichnikov v Minister for Immigration and Multicultural Affairs (2003) 197 ALR 389 at 394 [24] per Gummow and Callinan JJ, Hayne J agreeing at 408 [95]. Although not expressly so identified in that case, the constructive failure to exercise jurisdiction may be seen as a failure to carry out the review required by the Act. The joint judgment of Gummow and Callinan JJ in Dranichnikov described the task of the Tribunal where the applicant relied upon membership of a particular social group. Their Honours said (at [26]):
… the task of the tribunal involves a number of steps. First the tribunal needs to determine whether the group or class to which an applicant claims to belong is capable of constituting a social group for the purposes of the Convention. That determination in part at least involves a question of law. If that question is answered affirmatively, the next question, one of fact, is whether the applicant is a member of that class. There then follow the questions whether the applicant has a fear, whether the fear is well-founded, and if it is, whether it is for a Convention reason.
…
[63] It is plain enough, in the light of Dranichnikov, that a failure by the Tribunal to deal with a claim raised by the evidence and the contentions before it which, if resolved in one way, would or could be dispositive of the review, can constitute a failure of procedural fairness or a failure to conduct the review required by the Act and thereby a jurisdictional error. It follows that if the Tribunal makes an error of fact in misunderstanding or misconstruing a claim advanced by the applicant and bases its conclusion in whole or in part upon the claim so misunderstood or misconstrued its error is tantamount to a failure to consider the claim and on that basis can constitute jurisdictional error. The same may be true if a claim is raised by the evidence, albeit not expressly by the applicant, and is misunderstood or misconstrued by the Tribunal. Every case must be considered according to its own circumstances. Error of fact, although amounting to misconstruction of an applicant's claim, may be of no consequence to the outcome…
51 Applying those principles here, we consider that the Tribunal fell into jurisdictional error for the following reasons. First, the appellant's primary claim was that he feared serious harm and/or significant harm if he were returned to Rwanda because of his close relationship with the General and the harm which he had experienced while he was in Rwanda as a result of that association. An integer or element of that claim was that he had received threatening telephone calls around mid-2011 in which express reference was made to his association with the General. As noted at [40] above, those phone calls were made only a few months before he left Rwanda for Australia.
52 Secondly, in order to discharge its statutory review function, the Tribunal was required to consider the appellant's claims and their integers. In the circumstances here, this obliged the Tribunal to determine whether or not it accepted that the threatening telephone calls had been made and, if it found that they had, to proceed to determine whether it accepted the appellant's claims that he was threatened in those calls that he would "disappear from the earth" and that such threats were made because of his association with the General. If the Tribunal made findings of fact which were favourable to the appellant on these matters, they would be material in that they could indicate that, contrary to the Tribunal's ultimate finding, the appellant remained a person of interest in mid-2011 because of his association with the General. If that fact was accepted, it indicated that the appellant was a person of interest well after he ceased reporting to the police the previous year, contrary to the Tribunal's finding.
53 Thirdly, instead of making clear findings one way or the other on this element of the appellant's claim (and it is plain that the Tribunal appreciated that this was an element of his claim because it purported to deal with it in its reasons for decision), the Tribunal was content to proceed on the basis that, even if the threatening calls had been made as alleged by the appellant, he was able to "deal" with them by changing his telephone number and ceasing to answer calls from unknown numbers. With respect to the Tribunal, that reasoning was inadequate to discharge the Tribunal's review function in respect of this matter. That is because:
(a) the fact that the calls stopped because of the appellant changing his telephone number and ceasing to take calls from unknown numbers did not mean that the threats were empty and would not be carried out if an opportunity arose; and
(b) equally significantly, if the Tribunal assumed that the calls had been made as alleged by the appellant (and it is not clear that it did make that assumption even though it used the phrase "even if"), it was then incumbent on the Tribunal to turn its mind to the significance of the fact that the threats were said to be connected to the appellant's association with the General and that, as at mid-2011, he remained a person of interest to the unknown caller(s).
54 Fourthly, there is the curious reference at the end of both [99] and [107] of the Tribunal's reasons for decision to the Tribunal's finding that it did not accept in all the circumstances that the telephone calls could be considered to constitute persecution involving "serious harm" as required by s 91R(1)(b) of the Act. Those statements strongly suggest that the Tribunal viewed the appellant's claims in relation to the telephone calls as being that the telephone calls themselves constituted persecution involving "serious harm" for the purposes of that provision. This constitutes a fundamental misunderstanding or mischaracterisation of the claim which was being made, or at least an element of it. The appellant was not claiming that the making of the telephone calls themselves constituted serious harm. Rather, it was the threats that were made to him in those calls that were claimed to constitute the serious harm and also to evidence that the claimed serious harm was related to the appellant's relationship with the General. The calls could have been and were avoided by the appellant changing his telephone number and ceasing to take calls from unknown numbers, but the threats remained. The appellant's claim was that, if he returned to Rwanda, there was a risk that those threats would be carried out. The Tribunal never addressed or determined that element of his claims. This matter was relevant not only to his claim to fear persecution under the Refugee Convention but also to his claim that he was at risk of significant harm for the purposes of s 36(2)(aa) of the Act.
55 We reject the Minister's submission that these statements at the end of [99] and [107] of the Tribunal's reasons for decision do not reveal a misunderstanding of the appellant's claims and that the statements can be put to one side because they were unnecessary to the Tribunal's conclusion that there was no real chance that the appellant would suffer serious harm in the future. The fundamental difficulty with that submission is that it is predicated on the acceptance of the correctness of the Tribunal's reasoning that, even if the phone calls occurred, they ceased when the appellant changed his telephone numbers and stopped taking calls from unknown numbers. As noted above, that reasoning is seriously deficient and fails to grapple with the appellant's claims relating to and arising from the threatening phone calls.
56 The claims relating to the threatening phone calls were an element of the appellant's claim to fear serious or significant harm if he were returned to Rwanda. The Tribunal appreciated that this was a claim which was expressly made and one which arose clearly on the materials before the Tribunal (see NABE at [61]-[62]). Because of the way the Tribunal dealt with that claim, it remains "unresolved". As Flick J observed in not dissimilar circumstances in SZRRD v Minister for Immigration and Border Protection [2015] FCA 577 at [17]:
It matters not why the now Appellant's claim remains unresolved; it may not have been resolved by reason of error, misunderstanding, or inadvertence on the part of the Tribunal. However it occurred, the jurisdictional error remains.
