The Applicants' Challenge to the Section 10 Decision
91 It is apparent from the Statement of Reasons in respect of his s 10 decision furnished by the Minister to the applicants that the applicants failed to satisfy the Minister that Lot 208 is a significant Aboriginal area (within the meaning of the Act) and thus failed at the outset to meet the first precondition for action by the Minister mandated by s 10. By the time the Minister made the s 10 decision, he had received a s 10(1)(c) report from Mr Waters, had considered that report and the representations attached to it and had considered such other matters as he thought relevant. Further, it may be assumed that, had it become necessary to consider the matter, the Minister would probably have been satisfied that Lot 208 was under threat of desecration within the meaning of the Act.
92 Significant Aboriginal area is defined in the Act. Lot 208 is an area of land in Australia. Of that, there can be no doubt and, of that, the Minister was satisfied. The difficulty for the applicants, insofar as the Minister's s 10 decision is concerned, is that the Minister was not satisfied that Lot 208 was … an area of particular significance to Aboriginals in accordance with Aboriginal tradition.
93 The critical conclusion reached by the Minister is found in par 46 of his Statement of Reasons provided in respect of the s 10 decision. In that paragraph, he stated that he accepted that a massacre had occurred, that it had commenced approximately 2 km south of Lot 208 and that persons who were attacked south of Lot 208 may have fled to the north and may have died in the general vicinity of Lot 208 along with others who had camped in that general area. In earlier paragraphs of his Statement of Reasons, the Minister had referred to various observations made by Mr Waters in his report and, after considering the contents of that report and the documents attached to it, broadly accepted the conclusions stated in that report. At par 11(c) of his report, Mr Waters explained why it was that there was no reliable evidence that pinpointed Lot 208 (as distinct from other parcels or tracts of land in the vicinity) as a place upon which Aboriginal people were hunted down and slaughtered in the early aftermath of the massacre.
94 There is no doubt that the Minister had before him the video referred to in [16(a)(i)] above, Dr Weiner's three reports and the applicants' letter of claim. There is also no evidence to suggest that the Minister did not read and consider all of the attachments to Mr Waters' report, as he was bound to do under the Act.
95 Mr Oshlack manfully submitted that, in effect, the evidence which was before the Minister could lead a reasonable decision-maker acting honestly and reasonably to make only one decision, that is to say, to make a s 10 declaration. In support of that proposition, Mr Oshlack took me to all of the evidentiary material which he submitted made good his fundamental proposition. Mr Oshlack submitted that the Minister's refusal to make the requested s 10 declaration manifested an error of law because that decision could only have been arrived at by the application of a standard of proof higher than the balance of probabilities. Mr Oshlack relied upon the same material to demonstrate that the s 10 decision was manifestly unreasonable.
96 The Act does not require the Minister to apply any particular standard of proof in deciding whether or not he is satisfied that the area is a significant Aboriginal area within the meaning of the Act. Nor is there any principle which requires the application of a particular onus of proof or standard of proof in administrative decision making (see Yao-Jing v Minister for Immigration and Multicultural Affairs (1997) 74 FCR 275 at 288). The Minister may approach the finding of facts in such manner as he thinks fit subject to the principles to which I refer at [98]-[105] below. In his Statement of Reasons provided in support of the s 10 decision, the Minister did not state that he was applying any particular standard of proof.
97 In the present case, the obligation imposed upon the Minister to be satisfied that Lot 208 is a significant Aboriginal area required the Minister to act in good faith and not arbitrarily or capriciously. The Minister must consider all matters that he is required to consider and must not take into account irrelevant matters. A decision reached by the Minister which is so unreasonable that no reasonable decision-maker could properly have arrived at that decision may be set aside. These principles may be extracted from the judgment of Gibbs J in Buck v Bavone (1976) 135 CLR 110 at 118-119.
98 In recent times, the High Court has said that the opinion or satisfaction required by provisions of the sort with which the present case is concerned must be formed reasonably upon the material before the decision-maker (Enfield City Corporation v Development Assessment Commission (2000) 199 CLR 135 at 150; Gypsy Jokers Motorcycle Club Inc v Commissioner of Police (2008) 234 CLR 532 at [33] (per Gummow, Hayne, Heydon and Keifel JJ)).
99 The difficulty for the applicants in the present case is that the subject matter of the Minister's satisfaction under s 10(1)(c)(i) of the Act is essentially factual. The Minister must gain an appreciation of relevant Aboriginal tradition, must discern and consider the basis upon which Lot 208 is claimed by the applicants to be an area of particular significance to Aboriginals in accordance with that tradition, must evaluate that evidence and ultimately come to a view as to whether he is satisfied that Lot 208 is a significant Aboriginal area within the meaning of the Act.
100 In Broadbridge v Stammers (1987) 16 FCR 296 at 301, the Full Court, when dealing with a challenge to a decision which involved evaluation by the decision-maker of factual matters, cited, approved and relied upon the following passage from the speech of Lord Brightman in Puhlhofer v Hilingdon London Borough Council [1986] AC 484 at 518:
Where the existence or non-existence of a fact is left to the judgment and discretion of a public body and that fact involves a broad spectrum ranging from the obvious to the debatable to the just conceivable, it is the duty of the court to leave the decision of that fact to the public body to whom Parliament has entrusted the decision-making power save in a case where it is obvious that the public body, consciously or unconsciously, are acting perversely.
101 Gummow J, when sitting as a judge of this Court, cited Lord Brightman's speech in Puhlhofer v Hilingdon London Borough Council [1986] AC 484 with approval in Bienke v Minister for Primary Industries and Energy (1994) 125 ALR 156 at 165-166. His Honour said that the substance of Lord Brightman's speech was consistent with the approach taken by the High Court in Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321.
102 In Bienke v Minister for Primary Industries and Energy 125 ALR 156 at 166, his Honour went on to say:
Further, great caution must be shown in judicial review under s 39B of determinations resting upon factual matters where (i) the determinations in question were made after prolonged public debate, and (ii) being legislative in character, the determinations were subject to disallowance by either House of Parliament, and (iii) the disputed matters of fact turn upon expert knowledge and opinion, there is dispute between the experts, and there was no cross-examination upon that conflict.
103 Although these latter remarks made by his Honour are not directly applicable, the sentiments which underpin them certainly are. The thrust of the legislative scheme in the Act is to transfer to the reporter who must be appointed pursuant to s 10 of the Act the investigative role and to provide to the Minister the benefit of the reporter's investigations, the evidentiary material gathered by him or her and the recommendations made by him or her. Ordinarily, it will be the case that all relevant evidentiary material and points of view will be gathered by the reporter and made available to the Minister.
104 In the present case, the Minister had the benefit of all evidentiary material, the considered views of Mr Waters, the benefit of the applicants' views and opinions and all of the attachments to Mr Waters' report.
105 For the applicants to succeed in their contentions, they must demonstrate either that the Minister has acted perversely or that his findings or inferences of fact are simply not supported by any probative material or logical grounds (see Minister for Immigration and Multicultural Affairs v Eshetu (1999) 197 CLR 611 at [145] (per Gummow J)).
106 At bottom, Mr Oshlack's submissions come to this: the applicants disagree with the ultimate conclusion reached by the Minister to the effect that there was no reliable evidence establishing that any Aboriginal people died on Lot 208 in the aftermath of the massacre. The applicants disagree with that decision because they firmly and genuinely believe that Aboriginal people did die on Lot 208 in significant numbers after the initial attack and that there was a great deal of evidence to support that conclusion.
107 It is, of course, always difficult to prove with any significant degree of precision facts and circumstances which occurred so long ago where records are unreliable and inadequate and this factor has to be taken into account in the present case. However, I am unable to conclude that, in making the decision which he did, the Minister acted perversely or based his decision on findings or inferences of fact which were not supported by any probative material and which were not made on logical grounds. The Minister has explained his reasoning process. That process, and the findings which he made, cannot be criticised on the bases to which I have just referred. He had Mr Waters' report and he had Mr Waters' views. He had all of the material attached to that report. In the end, I am driven to conclude that it was fairly open to the Minister to make the decision which he did. In a matter such as this, it would not be enough to justify the relief which has been claimed for me to decide that I would have come to a different view. In the end, whilst the applicants' submissions were supported by a careful analysis of the evidentiary material in an endeavour to persuade me that a different decision from that which had been made by the Minister was warranted, I have not been persuaded that the Minister's decision discloses reviewable error.
108 The conclusions to which I have come and which I have expressed at [106] and [107] above also deal with the applicants' contention that the s 10 decision was manifestly unreasonable.
109 The challenge to the way in which the Minister dealt with the archaeological claim advanced by the applicants in their letter dated 16 June 2008 was only faintly supported in submissions made at the hearing. I have been unable to discern any reviewable error in the way in which the Minister dealt with that matter. The ground of review based upon the potential for important archaeological material to be found on Lot 208 also fails.
