Separate treatment of cases
13 The appellant submitted that Gray J should have held that the failure to consider the evidence of the appellant's brother in the appellant's case resulted in the RRT's decision being affected by legal error. It was submitted that the RRT had excluded relevant material from its consideration and thereby erred in law.
14 At [74] in his reasons for judgment Gray J said:
"The ground of error of law is not made out. It cannot be suggested that, in failing to take into account the evidence of the other brother in each case, the Tribunal failed to take into account relevant considerations in the sense in which that expression is used in the passage of Yusuf quoted above. Nothing in the nature of the jurisdiction exercised by the Tribunal under the Migration Act in relation to applications for protection visas suggests that it was obliged to take into account particular evidence available to it, as distinct from being obliged to consider the way in which each applicant put his case for a protection visa. Thus, there was no error of law of a kind identified in Yusuf."
15 We agree, with respect, with the views there expressed by his Honour.
16 In Minister for Immigration and Multicultural Affairs v Yusuf [2001] HCA 30, (2001) 180 ALR 1 at [82], ALR 21-22, McHugh, Gummow and Hayne JJ said:
"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, 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 The evidence of the appellant's brother in his case, if viewed as relevant material in the appellant's case, can be said to have been ignored by the RRT. However, it is another thing to say that relevant material has been ignored "in a way that affects the exercise of power". For that element to be satisfied it must be shown that the RRT was bound to take into account the evidence which it ignored; see Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24 at 39-40 per Mason J. We can discern no basis upon which it can be said that the RRT was so bound.
18 We note that the RRT informed the appellant at the outset of the hearing of the material that it had before it, and invited him to place before it any further evidence. It was abundantly clear from what the RRT had said that the statement made by the appellant's brother was not part of the material that was before the RRT at that stage. At no time did the appellant in his case, or the appellant's brother in that case, seek that the RRT have regard to the evidence given by each of them when considering its decision in both matters. Each brother was accompanied by a solicitor at the RRT hearings. That solicitor was also a registered migration agent and could have been expected to invite the RRT to take into account material led in relation to one case when considering the other had it been thought appropriate to do so.
19 It also must be remembered that if the RRT had taken into account the evidence given by each applicant in the case brought by the other, it would have been bound to take into account not only those matters which supported each case but also those matters which were adverse to the interests of each applicant.
20 Counsel for the appellant also contended that the appellant was denied a reasonable opportunity to give evidence and present arguments before the RRT as required by s425(1) of the Act. That subsection provides:
"(1) The Tribunal must invite the applicant to appear before the Tribunal to give evidence and present arguments relating to the issues arising in relation to the decision under review."
21 In Win v Minister for Immigration and Multicultural Affairs [2001] FCA 56, (2001) 105 FCR 212 at [24], FCR 218, a Full Court held that an invitation to attend a hearing before the RRT satisfied the requirements of s425(1) of the Act. Win was recently followed in that respect by the Full Court in Algama v Minister for Immigration and Multicultural Affairs [2001] FCA 1884 at [56]. Further as Gray J said in Chaddha v Minister for Immigration and Multicultural Affairs [2002] FCA 92 at [14]:
"Section 425 in its current form has been considered in several authorities. It is clear that, in its current form, the section limits the obligation of the Tribunal to extending an invitation to an applicant and does not require the Tribunal to take further steps to ensure that an applicant avails himself or herself of the opportunity."
