Costs of the proceeding
18 In my opinion the appropriate position is that each party should bear its own costs of this proceeding. Given that the parties made quite different submissions about the exercise of the costs discretion, it is appropriate there be an order to that effect.
19 I accept Mr Helmbright's submission that this proceeding had an aspect of public importance. It was the first contested trial on whether this Court was bound to apply the test in Mabo (No 2) when applying Love/Thoms, and as to what the content of that test was, including the Minister's submissions about the "native title approach" that was required. The parties' submissions, and the Court's reasons, demonstrate there were a considerable number of issues to be worked through, for the first time since the decision in Love/Thoms.
20 Added to the features of public importance is consideration of the substantive outcome in the proceeding. No party was wholly successful in the position it took. The applicant failed on his primary position that the Court could apply the Tasmanian Dam Case approach, and then on the evidence failed to meet the second aspect of the mutual recognition test in Mabo (No 2). The Minister's argument about how Love/Thoms should be understood was also rejected, leading to a rejection of the Minister's narrow "native title approach": see reasons at [215]-[275]. The Court adopted a broader application of the Mabo (No 2) test, which I accept was more akin to the alternative approach submitted by mtwAC. To identify these matters is not to engage in an issue-by-issue approach to the costs discretion (cf Firebird Global Master Fund II Ltd v Republic of Nauru (No 2) [2015] HCA 53; 90 ALJR 270 at [6]) but rather to illustrate that in this case if one recalls the purpose of a costs order being to compensate a party, there is no party in this proceeding whose position was so plainly vindicated that it is obvious that party should be compensated for the costs incurred in putting that position.
21 Although it is true, as the Minister submits, that costs orders were made against the unsuccessful individual parties in Singh and in Benbrika, that was at ultimate appellate level rather than at trial level. Different considerations may apply. Both the subject matter of the proceeding (eg, that it has a constitutional aspect) and what is at stake (a party's liberty) are factors which may contribute to the way in which the costs discretion is exercised, and it may be that such matters and their contribution to the proceeding having a character of public importance is greater at the trial level.
22 While the situation is not the same, the observations of Goldberg J in Cabal v United Mexican States (No 6) [2000] FCA 651; 174 ALR 747 at [22] are in my respectful opinion persuasive in the current context:
Although an order for costs is made to compensate a successful party for the expenses incurred in responding to an application or proceeding, that principle of compensation should yield in favour of the principle that a person detained by authority of the State should not be deterred by a potential costs order from seeking his or her liberty. There is a public interest in ensuring that persons detained against their will should not have any impediment put in their way which will inhibit them in seeking their liberty. In my view that public interest outweighs the general rule that a successful party is to be compensated for its costs by the unsuccessful party. In particular is this so where the costs are incurred by the State under whose authority the person is detained.
23 Goldberg J's decision related to an unsuccessful bail application under the Extradition Act 1988 (Cth). It was a first instance decision, as is this. Mr Helmbright's liberty is in jeopardy if his visa is cancelled, as is his ability to remain in Australia. To avoid that jeopardy, he is compelled to seek to prove what the Court found at trial had always been a feature of his family life - that his family, and he, have for several generations considered themselves Aboriginal Australians, as well as Maori People. As the Court found, this state of affairs existed for Mr Helmbright and his family long before Love/Thoms. Adapting what was said by Goldberg J in Cabal (No 6), even if the public importance of this proceeding is put to one side (which it should not be), in my opinion there is a public interest in ensuring that people in the position of Mr Helmbright are not inhibited in seeking to prove they are not aliens and therefore not subject to detention and removal from Australia. Especially in the context of the treatment of First Nations Peoples in this country, there should be no unnecessary obstacles placed in the way of those who identify as First Nations People in proving what they contend is their rightful status under the Constitution. Of course, if a proceeding is conducted vexatiously, irresponsibly, or in a way which unnecessarily and inappropriately causes other parties to incur costs, this kind of public interest may not prevail. There was no suggestion that Mr Helmbright conducted his case through his legal representatives other than responsibly and co-operatively, at every turn.
24 I do not consider the fact that Mr Helmbright was cross-examined tends one way or the other on the costs discretion. This was a trial; the Minister was entitled to cross-examine Mr Helmbright, and did so economically and only on particular issues.
25 Nor do I consider that the fact that the Minister's costs come from public funds is a factor which supports the making of a costs order (see [8] of the Minister's submissions). The Minister is charged with the administration of the Migration Act 1958 (Cth), and participation in litigation concerning powers exercised under that Act is a core aspect of discharging that responsibility. Likewise for the role of the Commonwealth in the maintenance and execution of the Constitution and the laws made under it. This factor tends neither for nor against the exercise of discretion in this case.
26 Similarly, the submission on behalf of Mr Helmbright that his legal representation was provided on a conditional basis with recoverable fees limited to any amount of costs paid by the respondent pursuant to an order of the Court tends neither for nor against the exercise of discretion in this case.
