The "jurisdictional fact" presented as a criterion for the operation of each of these sub-sections is of a special
nature because (i) on the face of the statute the jurisdictional fact is expressed in subjective terms, and (ii) its subject matter is not a state of fact in the ordinary sense, but entitlement as a matter of law upon a proper construction of the regulations. However, the determination of the existence of an entitlement to grant of an entry permit, and the interpretation of the regulations which this involves, in turn may call for an assessment of matters of fact. In this way, albeit indirectly, a fact finding process by the Minister is involved. The result is that the written decision of the Tribunal must include "material questions of fact" within the sense of sub-s. 135 (1) of the Act.
In England, particularly since Secretary of State for Education and Science v Tameside Metropolitan Borough Council [1977] AC 1014, a provision framed in a "subjective form" such as "if the Secretary of State is satisfied ..." usually will be construed so as not to exclude judicial review. A similar position had been reached earlier in Australia. Before us, both sides accepted the statement of principle by Gibbs J in Buck v Bavone (1976) 135 CLR 110 at 118-19. His Honour said:
"It is not uncommon for statutes to provide that a board or other authority shall or may take certain action if it is satisfied of the existence of certain matters specified in the statute. Whether the decision of the authority under such a statute can be effectively reviewed by the courts will often largely depend on the nature of the matters of which the authority is required to be satisfied. In all such cases the authority must act in good faith; it cannot act merely arbitrarily or capriciously. Moreover, a person affected will obtain relief from the courts if he can show that the authority has misdirected itself in law or that it has failed to consider matters that it was required to consider or has taken irrelevant matters into account. Even if none of these things can be established, the courts will interfere if the decision reached by the authority appears so unreasonable that no reasonable authority could properly have arrived at it. However, where the matter of which the authority is required to be satisfied is a matter of opinion or policy or taste it may be very difficult to show that it has erred in one of these ways, or that its decision could not reasonably have been reached. In such cases the authority will be left with a very wide discretion which cannot be effectively reviewed by the courts."
At this stage, several points should be made.
First, under general law principles, error in fact finding does not necessarily involve an error of law. Mason CJ explained the Australian position as follows, in Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 at 355-6:
"So, in the context of judicial review, it has been accepted that the making of findings and the drawing of inferences in the absence of evidence is an error of law: Sinclair v Maryborough Mining Warden (1975) 132 CLR 473 at 480, 483.
But it is said that '[t]here is no error of law simply in making a wrong finding of fact': Waterford v The Commonwealth (1987) 163 CLR 54 at 77, per Brennan J. Similarly, Menzies J observed in Reg. v District Court; Ex parte White (1966) 116 CLR 644 at 654:
'Even if the reasoning whereby the Court reached its conclusion of fact were demonstrably unsound, this would not amount to an error of law on the face of the record. To establish some faulty (e.g. illogical) inference of fact would not disclose an error of law.'
Thus, at common law, according to the Australian authorities, want of logic is not synonymous with error of law. So long as there is some basis for an inference - in other words, the particular inference is reasonably open - even if that inference appears to have been drawn as a result of illogical reasoning, there is no place for judicial review because no error of law has taken place."
Secondly, the term "perversely" used in House of Lords authority adopted by the Full Court in decisions such as Broadbridge v Stammers (1987) 16 FCR 296 at 300-301, and Apthorpe v Repatriation Commission (1987) 77 ALR 42 at 53-4, signifies that the fact finding administrative decision maker acted without any probative material, so that a finding of fact will be reviewable for error of law at common law on the ground that there was no probative material to support it: Bond at 358-360.
Thirdly, in our view, the reference by Gibbs J. in Buck v Bavone supra to fact finding in respect of what is a matter of opinion or policy or taste includes a case such as the present where what is at issue is the existence of "strong compassionate or humanitarian grounds" and the like. Conclusions on such matters may be very much a matter of opinion and thus not readily susceptible to review for error of law; see Kioa v West (1985) 159 CLR 550 at 582, per Mason J.
Fourthly, in considering various submissions made on the appeal, it is important to bear in mind that the jurisdiction conferred upon this Court by s. 138 of the Act, to consider error arising "on a question of law", differs in important respects from the jurisdiction exercised by the Court upon an application under the Administrative Decisions (Judicial Review) Act 1977 ("the ADJR Act") for an order of review in respect of a decision of an administrative character made under an enactment. Section 138 of the Act by confining the subject matter of the "appeal" to a question of law calls into play in a case such as the present the general common law principles of administrative law as to the treatment of fact finding as error of law. On the other hand, the various grounds of review under sub-s. 5 (1) of the ADJR Act, particularly those in paras. (e), (f) and (h), together with the requirement of a "decision" present a particular framework for review on "no evidence" grounds. The subject is discussed in Curragh Queensland Mining Ltd v Daniel (1992) 34 FCR 212 at 219-224.
Paragraph (f) asks whether "the decision involved an error of law", and para. (h) whether "there was no evidence or other material to justify the making of the decision". Paragraph (e), in conjunction with para. (g) of sub-s. 5 (2), provides for review on the ground that the making of the decision was an improper exercise of the power conferred by the enactment because the exercise of that power was "so unreasonable that no reasonable person could have so exercised the power".
Finally, these three threads in s. 5 of the ADJR Act were drawn together by Mason CJ in Bond, supra at 358-360. His Honour considered paras. (f) and (h) and said:
"The better view, one which seeks to harmonise the two grounds of review, is to treat 'error of law' in section 5 (1) (f) as embracing the 'no evidence' ground as it was accepted and applied in Australia before the enactment of the AD(JR) Act and to treat the 'no evidence' ground in section 5 (1) (h), as elucidated in section 5 (3), as expanding that ground of review in the applications for which pars. (a) and (b) of section 5 (3) make provision. Within the area of operation of par. (a) it is enough to show an absence of evidence or material from which the decision-maker could reasonably be satisfied that the particular matter was established, that being a lesser burden than that of showing an absence of evidence (or material) to support the decision. This interpretation of the two grounds of review enables one to say that section 5 (1) (h) and (3) (a) have the effect of overcoming to a limited extent and in a limited area the restrictions on the traditional 'no evidence' ground considered by Barwick CJ and Gibbs J in Sinclair v Maryborough Mining Warden (1975) 132 CLR at 481, 483."
His Honour also (at 359) accepted that some findings of fact might be reviewed under para. (e), provided that the finding itself constituted a "decision" and was more than a step along the way to an ultimate determination. If a finding of fact does constitute a "decision", then, his Honour said (at 359-60) it will be "reviewable on the ground that there is no probative evidence to support it and an inference will be reviewable on the ground that it was not reasonably open on the facts, which amounts to the same thing".
What then is involved in the proposition that the process of fact finding in order to decide whether circumstances answer a statutory pre-condition to the imposition of an obligation upon the decision maker, may attract review for error of law where the decision could not "reasonably" have been reached? Is the fact finding made in the exercise of a discretionary power? The position was explained in the following passage from Apthorpe, supra at 54 which was relied upon by the appellant:
"It is not a discretionary finding, but nevertheless involves the weighing up of a large range of factors and the making of a value judgment or assessment in the light of the broad test which Parliament prescribed. The making of that judgment or assessment is one for the tribunal, not for the court in an appeal limited to issues of law. The issues in the present case essentially are concerned with whether, in applying to the facts the test prescribed by the Parliament in the broad language used by it, an error of law occurred."
