Summary of relevant statutory provisions and case law
15 The parties were agreed that the relevant provision in the NT Act concerning Mr Kemp's application to be joined as a party in the circumstances here is s 84(5), but for reasons which will shortly emerge s 84(3) should also be noted:
84 Parties

16 There was substantial agreement between the parties as to the relevant legal principles concerning joinder. Some of those principles were summarised by Branson J in earlier proceedings involving Mr Kemp, being Davis-Hurst on behalf of the Traditional Owners of Saltwater v New South Wales Minister for Land and Water Conservation [2003] FCA 541; 198 ALR 315 (Davis-Hurst joinder).
17 Drawing also on cases such as Byron Environment Centre Incorporated v Arakwal People (1997) 78 FCR 1 (Arakwal) and Walker v State of Western Australia [2002] FCA 869; 191 ALR 654 per French J, Wakka Wakka People #2 v State of Queensland [2005] FCA 1578 (Wakka Wakka People #2) per Kiefel J and Jacob v State of Western Australia [2014] FCA 1106 per McKerracher J, the relevant principles which guide the exercise of the Court's discretion include:
an interest sufficient to give a person the right to become a party to an application needs to take into account the fact that a party can in effect veto the process of mediation and conciliation which the NT Act favours, which suggests that the relevant interest must not be indirect, remote or lacking substance;
the nature and content of the right to become a party also suggests that the interests must be capable of clear definition and be of such a character that they may be affected in a demonstrable way by a determination of native title to which the application relates;
the interest need not be proprietary or even legal or equitable in nature, however, the interest must be "genuine and not indirect, remote or lacking in substance";
a person who has "a special, well-established non-proprietary connection with land or waters which is of significance to that person" may have a sufficient interest;
other discretionary considerations may be relevant, including the following factors identified by Gilmour J in Barunga v Western Australia (No 2) [2011] FCA 755:
(i) because a determination of native title is a proceeding in rem and binds non-parties, it is fundamental that an order which directly affects a third person's rights or liabilities should not be made unless the person is joined as a party;
(ii) if joinder means that there will be consideration of rights and interests of the joined party which would lead to a more accurate definition of the native title rights and interests claimed, this is a factor in favour of joinder;
(iii) the party joined is put in the position to protect native title rights and interests which they claim to hold;
(iv) whether the interest asserted by the third party can be protected by some other mechanism;
(v) whether the applicant for native title determination would be prejudiced if the third party is joined as a party; and
(vi) the history of the proceedings, which includes the effects of delay and the resource implications of joinder for all parties to the proceeding (see also Allen on behalf of the Nyamal People # 1 v State of Western Australia [2018] FCA 320 at [56] per Barker J).
18 The whole of the relevant circumstances should be taken into account in determining whether or not to join a party to the proceedings, as was emphasised by Rares J in TJ (on behalf of the Yindjibarndi People) v State of Western Australia [2016] FCA 553 at [164]:
164 However, there will also be persons who have a disagreement with an authorised applicant's conduct of a native title claim or the claim itself, but whose rights or interests will still be affected by a determination of the claim, so that it will be appropriate or in the interests of justice to join those persons as parties to the proceedings. And, the interests of justice relevant to an application under s 84(5) must be assessed in the whole of the circumstances, including the stage that the proceedings have reached when the application is made and the consequences of the joinder, or refusal to order it, on all of the parties and the person applying to be joined. A consideration that may be relevant is the role that the State or Territory Government, as the representative of the community where the land and waters claimed are, has played in the litigation (see Munn (for and on behalf of the Gunggari People) v Queensland (2001) 115 FCR 109 at 115 [29] per Emmett J), as well as the position advanced by other respondents in relation to the claim in the context of the rights or interests that the person seeking to be joined wishes to advance.
19 Of potential significance to the determination of Mr Kemp's application is a series of cases which draw a distinction between a person who seeks to be joined as a respondent to a native title proceeding with a view to obtaining a positive determination of native title, as opposed to the situation where the person wishes to protect native title rights or interests from adverse ramifications. The relevant principles are helpfully summarised by McKerracher J in A.D. (deceased) on behalf of the Mirning People v State of Western Australia (No 2) [2013] FCA 1000 (Mirning People) at [56] and [57]:
56 Although there is a broad discretion conferred by s 84(5) NTA, the question of whether or not the discretion should be exercised in favour of joining a person as a party will depend on the circumstances of each case including the history of the matter. It must be apparent that there is at least prima facie an interest warranting exercise of the discretion under s 85(5) NTA: Isaacs on behalf of the Turrbal People v State of Queensland (No 2) [2011] FCA 942 per Reeves J (at [8]) and Wakka Wakka People # 2 v State of Queensland [2005] FCA 1578 per Kiefel J (at [6]). A fact to bear in mind is that once a person is joined as a party he or she has the power to veto the process of mediation and conciliation that the NTA favours. This makes it all the more important that the interest is capable of clear definition and of a character that may be affected in a demonstrable way by the determination in relation to the application: Byron per Black CJ (at 7-8). In Isaacs, Reeves J concluded that the interlocutory applicants had shown at least on a prima facie basis that the native title rights and interests which they claimed to hold could be affected by a determination of the application, however, joinder was not permitted. His Honour held (at [18]) that it was now well settled law that:
where a person is seeking to be joined as a respondent to a native title proceeding on the basis that he or she claims to hold native title rights and interests in an area of land or waters that may be affected by a determination in those proceedings … [that is permissible only] if he or she wishes to pursue a personal claim or interest in defensively asserting those native title right or interests or, in other words, to protect them from erosion, deletion or discount.
57 Additionally, as Reeves J noted in Isaacs (at [19]), if a person wishes to obtain a positive determination of native title then the NTA prescribes that the only method by which that can be achieved is by an application under s 13(1) NTA, complying with the requirements of s 61 and s 251B NTA: see also Commonwealth v Clifton (2007) 164 FCR 355 and Moses v Western Australia (2007) 160 FCR 148 (at [18]). A person cannot be joined as a respondent party if his or her purpose in being so joined is to act as a representative to assert native title rights on behalf of other people. That was the position taken by the interlocutory applicant in Isaacs as there was a positive assertion of native title rights and interests rather than the pursuit of any personal interest of protecting native title rights and interests.
20 In Davis-Hurst joinder, Branson J ordered that Mr Kemp be joined as a party in two proceedings relying primarily on the following matters:
(a) unchallenged evidence which established that Mr Kemp is a descendant of the Pirripaayi people, who are traditionally associated by Aboriginal law and custom with an area which included the land the subject of the two native title determination applications;
(b) Mr Kemp's concern that, while he did not wish to advance a claim for a determination of native title in respect of the relevant land either on his own behalf or on behalf of the Pirripaaya people, a native title determination in favour of the application in both proceedings would "give formal recognition to a version of history that does not recognise the Pirripaayi people as the traditional owners of Saltwater";
(c) Mr Kemp's concern that the applicant in both proceedings was the wrong person to represent the claimant group because, based on Mr Kemp's understanding of traditional Aboriginal law and custom, a woman could not claim the areas of land the subject of the applications for determination; and
(d) Mr Kemp's concern that the applicant may not accept, or perhaps be aware of, the correct Dreaming story and the customary laws of the area in question.
21 Justice Branson noted at [16] that Mr Kemp had "undertaken considerable research into the history of the claim areas". Her Honour added that any determination by the Court might be seen to give "legitimacy to an understanding of that history which [Mr Kemp] does not accept is complete" and that any such determination could adversely affect his ability "to share the knowledge that he has acquired about the Pirripaayi people and his capacity to keep alive Pirripaayi language and customary laws".
22 It is evident that Mr Kemp has been involved in several previous native title proceedings. In addition to Davis-Hurst joinder, he actively participated in the following proceedings: Kemp v Registrar, Native Title Tribunal [2006] FCA 568; Kemp v Native Title Registrar [2006] FCA 939 and Davis-Hurst on behalf of the Kattang People v Minister for Lands [2009] FCA 725.
