5.2 The Minister's submission that an error in construction would not constitute a jurisdictional error
31 Counsel for the Minister, however, submitted that the question for the Tribunal under item 6B51 was a question of fact involving a comparison between what the applicant has actually been employed to do, with what the nominated skilled occupation requires. He submitted that the words "closely related" should be given their ordinary meaning as a consequence of which, if the decision-maker should find that particular facts fall or do not fall within the words, he makes a finding of fact only. There can be no jurisdictional error in the Minister's submission where, as here, the question is a mixed question of fact and law.
32 In support of his submission, the Minister sought to rely on Constantino. In particular, in obiter, Jacobson J observed at 573 [48] that:
Even if the construction adopted by the tribunal is incorrect, it seems to me that there can be no jurisdictional error in its decision. This is because the question which arose in the tribunal was a question of mixed fact and law. It was not a question as to which only one conclusion was open and the tribunal did not so misdirected itself as to take its decision beyond jurisdiction: Vetter v Lake Macquarie City Council (2001) 202 CLR 439… at [24]-[27].
33 His Honour then observed that this approach had been adopted in Prasad v Minister for Immigration and Citizenship (2012) 128 ALD 113 at [19] (Logan J) and in Dhiman v Minister for Immigration and Citizenship [2012] FCA 1254 at [22] (Katzmann J). Counsel for the Minister in this appeal also submitted that the Court's approach in Vetter is "the correct analysis here".
34 With respect, however, the High Court's decision in Vetter v Lake Macquarie City Council (2001) 202 CLR 439 does not stand for the proposition which the Minister contends and for which it is quoted in Constantino. Vetter was not concerned with correcting jurisdictional error by an administrative tribunal in the exercise of jurisdiction under s 39B of the Judiciary Act 1903 (Cth) which mirrors that conferred by s 75(v) of the Constitution. In Vetter (which was decided before Kirk v Industrial Court of New South Wales (2010) 239 CLR 531), the question was whether the appellant had identified a question of law so as to enliven the jurisdiction of the New South Wales Court of Appeal to hear an appeal from the Compensation Court of New South Wales under s 32 of the Compensation Court Act 1984 (NSW). In that context, in their joint judgment Gleeson CJ, Gummow and Callinan JJ said at 450 [24] that:
Whether facts as found answer a statutory description or satisfy statutory criteria will very frequently be exclusively a question of law. To put the matter another way… whether the facts found by the trial court can support the legal description given to them by the trial court is a question of law. However, not all questions involving mixed questions of law and fact are, or need to be susceptible of one correct answer only. Not infrequently, informed and experienced lawyers will apply different descriptions to a factual situation. That is why the test whether legal criteria have been met has been expressed in language of the kind used by Jordan CJ in Australian Gas Light Company v Valuer General [(1940) 40 SR (NSW 126]:
'[I]f the facts inferred… from the evidence… are necessarily within the description of a word or phrase in the statute or necessarily outside that description, a contrary decision is wrong in law.'
35 Their Honours then cited with apparent approval the statement by Mason J (with whom Gibbs, Stephen, Murphy and Aickin JJ agreed) in Hope v Bathurst City Council (1980) 144 CLR 1 at 7 that:
Many authorities can be found to sustain the proposition that the question whether facts fully found fall within the provisions of a statutory enactment properly construed is a question of law…
However, special considerations apply when we are confronted with a statute which on examination is found to use words according to their common understanding and the question is whether the facts as found fall within these words. Brutus v Cozens [[1973] AC 854] was just such a case. The only question raised was whether the appellant's behaviour was "insulting". As it was not unreasonable to hold that his behaviour was insulting, the question was one of fact.
36 Nor does the decision of Katzmann J in Dhiman v Minister for Immigration and Citizenship [2012] FCA 1254 support the proposition put by the Minister. In that decision at [22], her Honour concluded that, even if error was demonstrated in the Tribunal's reasons, its findings were sustained by an independent ground. Katzmann J therefore concluded that any error would have been an error within jurisdiction.
37 Finally, the passage in the decision of Logan J in Prasad v Minister for Immigration and Citizenship (2012) 128 ALD 113 at [19] which was also cited in Constantino stands for the opposite contention to that put by the Minister here. The case was one concerning an application for a skilled 485 visa. His Honour found that the question of whether jurisdictional error had been demonstrated in the Tribunal's conclusion that a particular degree was not closely related to the nominated skill depended upon whether the Tribunal had correctly construed the terms of the relevant criterion in the regulations.
38 It follows, with respect, that I consider the proposition for which the Minister contends to be wrong. A contrary conclusion would constitute an unwarranted and significant erosion of the constitutionally entrenched jurisdiction to undertake judicial review in s 75(v) of the Constitution and the equivalent jurisdiction of this Court conferred by s 39B of the Judiciary Act 1903 (Cth). The fact that the Parliament has conditioned an exercise of power on a criterion expressed in ordinary, non-technical language and that the Tribunal in assessing whether the criterion is satisfied might be described as making a finding on a mixed question of fact and law cannot remove the Court's jurisdiction to determine whether the decision was made within lawful boundaries. As Gaudron, McHugh, Gummow, Kirby and Hayne JJ explained in Plaintiff S157/2002 v Commonwealth (2003) 211 CLR 476 at 513-514 [104], "[t]he reservation to this Court by the Constitution of the jurisdiction in all matters in which the named constitutional writs or an injunction are sought against an officer of the Commonwealth is a means of assuring to all people affected that officers of the Commonwealth obey the law and neither exceed nor neglect any jurisdiction which the law confers on them." It is trite than an administrative tribunal lacks authority either to authoritatively determine questions of law or to make an order or decision otherwise than in accordance with the law: Craig v South Australia (1995) 184 CLR 163 at 179; Plaintiff S157/2002 at 512 [98]; Kirk v Industrial Court of New South Wales (2010) 239 CLR 531 at 572 [67]; FTZK v Minister for Immigration and Border Protection (2014) 88 ALJR 754 at 772 [90]. In short, as the High Court stated in the oft quoted passage from Craig at 179 with respect to the grounds of judicial review of administrative decisions:
If such an administrative 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.
