CONSIDERATION
18 Section 426A is one of many provisions within Part 7 of the Act dealing with the review of protection visa decisions. The central obligation of the Tribunal under s 414 is to review decisions. How it is to conduct that review is specified in Div 4 of Part 7. The scope and purpose of Part 7 of the Act is to ensure that the Tribunal performs the function of review.
19 Section 426A confers a discretionary power. It is presumed that the legislature intended the power to be exercised reasonably.
20 What constitutes that standard relevant to the present appeal was explained by the plurality (Hayne, Kiefel and Bell JJ) in Minister for Immigration and Citizenship v Li (2013) 249 CLR 332; [2013] HCA 18 in the following passages:
68 ... The legal standard of unreasonableness should not be considered as limited to what is in effect an irrational, if not bizarre, decision - which is to say one that is so unreasonable that no reasonable person could have arrived at it - nor should Lord Greene MR be taken to have limited unreasonableness in this way in his judgment in Wednesbury.
...
72 ... Further, in Minister for Aboriginal Affairs v Peko-Wallsend Ltd, Mason J considered that the preferred ground for setting aside an administrative decision which has failed to give adequate weight to a relevant factor of great importance, or has given excessive weight to an irrelevant factor of no importance, is that the decision is "manifestly unreasonable". Whether a decision-maker be regarded, by reference to the scope and purpose of the statute, as having committed a particular error in reasoning, given disproportionate weight to some factor or reasoned illogically or irrationally, the final conclusion will in each case be that the decision-maker has been unreasonable in a legal sense.
...
76 As to the inferences that may be drawn by an appellate court, it was said in House v The King that an appellate court may infer that in some way there has been a failure properly to exercise the discretion "if upon the facts [the result] is unreasonable or plainly unjust". The same reasoning might apply to the review of the exercise of a statutory discretion, where unreasonableness is an inference drawn from the facts and from the matters falling for consideration in the exercise of the statutory power. ... Unreasonableness is a conclusion which may be applied to a decision which lacks an evident and intelligible justification.
[Footnotes omitted.]
21 When faced with an allegation that a decision is legally unreasonable, the Court is not asked to substitute its view of the merits of the exercise of the discretion. It exercises a supervisory function determining whether the decision conforms with the standard of reasonableness.
22 In the present case the Tribunal explained why it proceeded in the absence of the appellant. It said that the appellant was invited to appear and did not respond to the invitation. The Tribunal also said at [4]:
That letter was addressed to his last given address, provided by himself, which was the same address used by the by the [sic] department. A check was made to see if any change of address had been notified and, none has been.
23 Thus the Tribunal checked the address on the letter of invitation with the address previously used by the Department, and checked, presumably in its own records, to see whether there was any indication of any notification of a change of address. These steps were taken by the Tribunal to determine whether the applicant may not have received the invitation to the hearing. That was, of course, an obvious thing to do in the circumstances.
24 The steps were obvious in the circumstances because, as was known to the Tribunal, the appellant had appeared at the hearing before the delegate, and had filed a substantial and serious written submission in the Tribunal. These factors suggested that the appellant intended to pursue the application for a visa and to attend the hearing. Further, the nature of the application demonstrated that if the claims made were established the appellant was at risk of serious harm if returned to Sri Lanka.
25 The Tribunal had in its own records in the application for review the mobile phone number of the appellant.
26 Further, for the purpose of the hearing the Tribunal created a document entitled "Hearing Record". The document recorded all the details relevant to the hearing such as the place and time of the hearing. The document listed the witnesses to be called and the name of the member conducting the hearing. It seems to have been prepared in advance of the hearing so that the details of what occurred on the day could be inserted. The document included the name of the appellant and his mobile phone number written opposite his name. The obvious purpose of recording the mobile phone number was to provide a method which would allow the Tribunal to contact the appellant. Elementary common sense demanded that the Tribunal at least attempt to phone the appellant on the mobile phone number which it had in its records. To fail to do so was legally unreasonable. The Tribunal fell into jurisdictional error by not seeking to contact the appellant on the phone number which he had given the Tribunal.
27 The primary judge set out in his judgment the particulars of the grounds of application for review. The particulars included an assertion that the appellant provided the Tribunal with his mobile phone number. The primary judge did not deal with this factor. It was the critical factor which rendered the exercise of discretion unreasonable. It was determinative of the case.
28 Even if this factor had not been determinative of the case, the reasoning of the primary judge should not be upheld. In the circumstances outlined it was unreasonable for the Tribunal not to utilise the other information in its own records to attempt to contact the appellant. In addition to the mobile phone number it could have used the email address provided by the appellant. Furthermore, the statutory declaration filed in support of the application which was before the Tribunal indicated that Ms Symonds had assisted the appellant in formulating the written submission. Her mobile number was on the declaration. As she had assisted the appellant in formulating the written submission, contacting her was a likely way of getting in touch with the appellant. It is now clear, by virtue of the further evidence admitted on appeal, that an enquiry of the Department on 19 May 2014 would have shown that the appellant had notified the Department of his change in address. The primary judge had no good reason to reject the evidence of the appellant that he had notified the Department of the change of address, particularly in the absence of any cross examination. As the appellant received a letter from the Department on 22 May 2014 at the Aberfoyle Park address there was an almost irresistible inference that the appellant had notified the change before the date of the hearing on 19 May 2014.
29 The appellant has established that the decision of the Tribunal to proceed in his absence was legally unreasonable. He has thus established ground 4(b) of the notice of appeal. It is unnecessary to consider the other grounds of appeal.
30 In the result the appeal will be allowed with costs, the decision of the Tribunal will be quashed and the matter returned to the Tribunal for determination in accordance with law.
