Failure to Inquire in Accordance with Section 359
27 Dr Dinnen's report disclosed that Ms Nitu had been seeing a psychiatrist, Dr Samad, for some two years. However no report from Dr Samad was tendered to the Tribunal. At the commencement of the oral hearing before the Tribunal, the following exchange had occurred between the member, Mr Holloway, and counsel, Mr Dobbie, representing the applicant:
"MR HOLLOWAY: Have you got anything further, any submissions, Mr Dobbie?
MR DOBBIE: It is pleases the Tribunal, we have been seeking to get a psychiatric opinion in support of the application. We did obtain one earlier and I was going to forward it for consideration but when I read it again although it confirms that the psychological and physical dependency it doesn't give reasons why and I thought that wouldn't very helpful to the Tribunal. (sic)
MR HOLLOWAY: No.
MR DOBBIE: We have arranged for a psychological assessment to be done by Dr Anthony Dinnen next week, that was the earliest he could squeeze us in when we got notification of the hearing."
28 It is now submitted that, in the exchange cited, the applicant's adviser put the Tribunal on notice that he had material from another psychiatrist which confirmed psychological dependency. It is said that the Tribunal regarded it as important that no objective medical evidence had been provided at the hearing and discounted Dr Dinnen's report partly because he had not been seeing the applicant on a long term basis. It is submitted therefore that the reports of Dr Samad were material that was centrally relevant and readily available. It was submitted that when the Tribunal reached the point of discounting Dr Dinnen's evidence, the earlier reports by Dr Samad took on a new significance.
29 Generally speaking when a statute provides for a person to apply to some authority for the grant of a right or privilege the decision-maker is, absent some relevant statutory direction, entitled to rely upon the materials supplied by the applicant as that which is presented in favour of the application. There is no general duty on the decision-maker to seek additional material which may remedy deficiencies in the applicant's presentation - Turner v Minister for Immigration and Ethnic Affairs (1981) 35 ALR 388 at 392-393 (Toohey J); Kioa v West (1985) 159 CLR 550 at 587 (Mason J). As Hill J said in Enichem Anic Srl v Anti-Dumping Authority (1992) 111 ALR 178 at 190 (Gummow J agreeing):
"Decision-making is a function of the real world. A decision-maker is not bound to investigate each avenue that may be suggested to him by a party interested. Ultimately, a decision-maker must do the best on the material available after giving interested parties the right to be heard on the question."
30 There may be cases in which a decision maker who unreasonably fails to ascertain relevant facts known to be readily available will be taken to have exercised the decision-making power improperly. In Prasad v Minister for Immigration and Ethnic Affairs (1985) 6 FCR 155 at 170, Wilcox J said:
"It is no part of the duty of the decision-maker to make the applicant's case for him. It is not enough that the court find that the sounder course would have been to make inquiries. But, in a case where it is obvious that material is readily available which is centrally relevant to the decision to be made, it seems to me that to proceed to a decision without making any attempt to obtain that information may properly be described as an exercise of the decision-making power in a manner so unreasonable that no reasonable person would have so exercised it. It would follow that the court, on judicial review, should receive evidence as to the existence and nature of that information."
On judicial review at common law or under the ADJR Act, the Court is entitled to consider those facts which were known to the decision-maker, actually or constructively, together only with such additional facts as the decision-maker would have learned but for any unreasonable conduct by him - Prasad at 169 (Wilcox J) and Videto v Minister for Immigration and Ethnic Affairs (1985) 8 FCR 167 at 178 (Toohey J).
31 The possibility that, in certain circumstances, the failure of a decision-maker to make inquires would vitiate the purported exercise of a power as unreasonable was advanced by Wilcox J in Prasad and confirmed by the Full Court in Luu v Renevier (1989) 91 ALR 39 at 50:
"The underlying rationale of the approach suggested in Prasad is that the ground of unreasonableness, in the context of the Administrative Decisions (Judicial Review) Act 1977, may be related to the manner in which power is exercised.
.
.
.
One may say that the making of a particular decision was unreasonable - and, therefore, an improper exercise of the power - because it lacked a legally defensible foundation in the factual material or in logic. But, equally, one may be able to say that a decision is unreasonably made where, to the knowledge of the decision-maker, there is readily available to him or her other factual material, likely to be of critical importance in relation to a central issue for determination, and which has not been obtained."
It has been suggested that the failure to inquire may breach the duty to act fairly towards the applicant. In Detsongjarus v Minister for Immigration and Ethnic Affairs (1990) 21 ALD 139 at 143, Pincus J, after referring to Prasad, Kioa, Chan v Minister for Immigration and Ethnic Affairs (1989) 169 CLR 379 and Luu said that a decision-maker does not necessarily accord to an applicant for an entry permit the degree of fairness to which the applicant is entitled by considering only the material produced by the applicant. His Honour essayed four general propositions:
1. The decision-maker is not obliged to make the applicant's case.
2. The decision-maker ordinarily may decide the application on the basis of such information and material as the applicant puts forward.
3. The decision-maker may sometimes be obliged to make further inquiries where a proposed ground of objection is information obtained from a source other than the applicant, which information has been dealt with by the applicant.
4. Further information may have to be sought where the decision-maker knows that there is available other factual material likely to be of critical importance in relation to a central issue for determination. (143)
32 The cases cited arose in the context of judicial review under the Administrative Decisions (Judicial Review) Act 1977. The grounds of review available under that Act reflecting, and to some extent extending, common law grounds of judicial review are not all available in respect of decisions made under the Migration Act. The grounds upon which the Court may review such decisions, including the decision presently in issue, are confined to those set out in s 476. In Minister for Immigration and Ethnic Affairs v Singh (1997) 74 FCR 553, there was a question whether the duty of the Refugee Review Tribunal under s 420 to "…act according to substantial justice and merits of the case" required the Tribunal in appropriate circumstances to make inquiries on its own account in relation to an application pending before it. The issue upon which it was said to be obliged to make inquiries related to the authenticity of the documents purporting to be warrants for the arrest of the applicant for refugee status and his wife in their home country. The Court referred to s 424 of the Act, the equivalent provision for the Refugee Review Tribunal of s 359, which applies to the Migration Review Tribunal. The Court also referred to ss 425, 426 and 427 and said:
"These provisions show that the Tribunal's role in cases that come before it for review is not a passive one, although the circumstances in which the Tribunal could be found to be under an obligation to make a particular inquiry will no doubt be rare, as they have been in cases under the ADJR Act." (560-561)
This observation was made on the assumption, accepted for the purpose of argument that s 420, requiring the Tribunal to act according to substantial justice and the merits of the case, imposed a procedure to be observed in connection with the making of the decision, failure to observe which would be a ground of review under s 476(1)(a) of the Act. That assumption has now been falsified by the decision of the High Court in Minister for Immigration and Ethnic Affairs v Eshutu (1999) 197 CLR 611 also the discussion of this issue in Minister of State for Immigration and Ethnic Affairs v Teoh (1995) 183 CLR 273 at 289-290 (Mason CJ and Deane J), 302-303 (Toohey J), 304-305 (Gaudron J) and 320-321 (McHugh J). All of these decisions arise in settings where there was or was assumed to be a wider range of grounds of review available than is now the case under the Migration Act. So called Wednesbury unreasonableness is not available as a ground of review, nor is breach of the rules of natural justice save for the case of actual bias. No available ground has been suggested which might be relied upon to review a decision of the Migration Review Tribunal on the basis of its alleged failure to make inquiries. In any event, in the present case there was no such failure. The applicant's counsel told the Tribunal that he did not propose to rely upon the psychiatric reports which he now says the Tribunal should have asked him to produce. The submission is insupportable. Ground 1(b) therefore fails.
