THE NATURE OF THE ISSUE
19 As outlined above, the question of law relating to the operation of the 'past act' provisions of the NTA, in particular s 228, relates to the various mining tenements granted within the area of the Martu native title claim. The parties do not agree on the answer to that question.
20 Section 228 NTA provides:
228 Past act
Definition
(1) This section defines past act.
Acts before 1 July 1993 or 1 January 1994
(2) Subject to subsection (10), if:
(a) either:
(i) at any time before 1 July 1993 when native title existed in relation to particular land or waters, an act consisting of the making, amendment or repeal of legislation took place; or
(ii) at any time before 1 January 1994 when native title existed in relation to particular land or waters, any other act took place; and
(b) apart from this Act, the act was invalid to any extent, but it would have been valid to that extent if the native title did not exist;
the act is a past act in relation to the land or waters.
Options exercised on or after 1 January 1994 etc.
(3) Subject to subsection (10), an act that takes place on or after 1 January 1994 is a past act if:
(a) it would be a past act under subsection (2) if that subsection were not limited in its application to acts taking place before a particular day; and
(b) it takes place:
(i) in exercise of a legally enforceable right created by the making, amendment or repeal of legislation before 1 July 1993 or by any other act done before 1 January 1994; or
(ii) in giving effect to, or otherwise because of, an offer, commitment, arrangement or undertaking made or given in good faith before 1 July 1993, and of which there is written evidence created at or about the time the offer, commitment, arrangement or undertaking was made; and
(c) the act is not the making, amendment or repeal of legislation.
Extensions, renewals etc.
(4) Subject to subsections (6) and (10), an act (the later act) that takes place on or after 1 January 1994 is a past act if:
(a) the later act would be a past act under subsection (2) if that subsection were not limited in its application to acts taking place before a particular day; and
(b) an act (the earlier act) that is a past act because of any subsection of this section (including because of another application of this subsection) took place before the later act; and
(c) the earlier act created interests in a person and the later act creates interests in:
(i) the same person; or
(ii) another person who has acquired the interests of the first person (by assignment, succession or otherwise);
in relation to the whole or part of the land or waters to which the earlier act relates; and
(d) the interests created by the later act take effect before or immediately after the interests created by the earlier act cease to have effect; and
(e) the interests created by the later act permit activities of a similar kind to those permitted by the earlier act.
Examples of similar and dissimilar acts for the purposes of paragraph (4)(e)
(5) The following are examples for the purposes of paragraph (4)(e):
(a) the grant of a lease that permits mining only for a particular mineral followed by the grant of a lease that permits similar mining for another mineral is an example of a case where interests created by an earlier act permit activities that are of a similar kind to those permitted by a later act;
(b) the grant of a lease that permits only grazing followed by the grant of a lease that permits mining is an example of a case where interests created by an earlier act permit activities that are not of a similar kind to those permitted by a later act.
Cases excluded from subsection (4)
(6) Subsection (4) does not apply if:
(a) the earlier act was the creation of a non-proprietary interest in relation to land or waters and the later act is the creation of a proprietary interest in land or waters; or
(b) the earlier act was the creation of a proprietary interest in land or waters and the later act is the creation of a larger proprietary interest in land or waters; or
(c) if the earlier act contains a reservation or condition for the benefit of Aboriginal peoples or Torres Strait Islanders - the later act does not contain the same reservation or condition; or
(d) the earlier act or the later act is the making, amendment or repeal of legislation.
Example of earlier and later acts for the purposes of paragraph (6)(a)
(7) For the purposes of paragraph (6)(a), the issue of a licence followed by the grant of a lease is an example of an earlier act that is the creation of a non-proprietary interest in relation to land and a later act that is the creation of a proprietary interest in land.
Example of earlier and later acts for the purposes of paragraph (6)(b)
(8) For the purposes of paragraph (6)(b), the grant of a lease followed by the grant of a freehold estate is an example of an earlier act that is the creation of a proprietary interest in land and a later act that is the creation of a larger proprietary interest in land.
Other extensions, and developments, of earlier acts
(9) Subject to subsection (10), an act (the later act) that takes place on or after 1 January 1994 is a past act if:
(a) the later act would be a past act under subsection (2) if that subsection were not limited in its application to acts taking place before a particular day; and
(b) an act (the earlier act) that is a past act because of any subsection of this section took place before the later act; and
(c) the earlier act contained or conferred a reservation, condition, permission or authority under which the whole or part of the land or waters to which the earlier act related was to be used at a later time for a particular purpose (for example, a reservation for forestry purposes); and
(d) the later act is done in good faith under or in accordance with the reservation, condition, permission or authority (for example, the issue in good faith of a licence to take timber under a reservation for forestry purposes); and
(e) the later act is not the making, amendment or repeal of legislation.
Excluded acts
(10) An act is not a past act if it is:
(a) the Queensland Coast Islands Declaratory Act 1985 of Queensland; or
(b) any other act declared by the regulations to be an excluded act for the purposes of this paragraph.
21 By s 231 NTA, a category C past act is defined thus: 'A category C past act is a past act consisting of the grant of a mining lease'.
22 Section 10 RDA provides:
10 Rights to equality before the law
(1) If, by reason of, or of a provision of, a law of the Commonwealth or of a State or Territory, persons of a particular race, colour or national or ethnic origin do not enjoy a right that is enjoyed by persons of another race, colour or national or ethnic origin, or enjoy a right to a more limited extent than persons of another race, colour or national or ethnic origin, then, notwithstanding anything in that law, persons of the first mentioned race, colour or national or ethnic origin shall, by force of this section, enjoy that right to the same extent as persons of that other race, colour or national or ethnic origin.
(2) A reference in subsection (1) to a right includes a reference to a right of a kind referred to in Article 5 of the Convention.
(3) Where a law contains a provision that:
(a) authorizes property owned by an Aboriginal or a Torres Strait Islander to be managed by another person without the consent of the Aboriginal or Torres Strait Islander; or
(b) prevents or restricts an Aboriginal or a Torres Strait Islander from terminating the management by another person of property owned by the Aboriginal or Torres Strait Islander;
not being a provision that applies to persons generally without regard to their race, colour or national or ethnic origin, that provision shall be deemed to be a provision in relation to which subsection (1) applies and a reference in that subsection to a right includes a reference to a right of a person to manage property owned by the person.
23 The parties describe the legal debate in these terms:
'14. In short, the legal arguments of the Applicant and the First Respondent centre on whether the conclusion in Western Australia v Ward (2002) 213 CLR 1 ("Ward HC") as to the effect that a mining lease granted under the Western Australian Mining Act 1978 has on native title viz, that the Racial Discrimination Act 1975 (Cth) ("RDA") was not engaged to invalidate the grants of mining leases under the RDA, so that the grants were not category C past acts (Ward HC at [321]), is relevantly distinguishable in respect of pre-1994 mining leases.
15. In particular, a focus of the arguments is whether the RDA invalidates the pre-1994 mining leases and whether section 228(2)(b) of the NTA is thereby engaged to validate the mining leases as Category C past acts in respect of which the non-extinguishment principle applies.'
24 What was said by Gleeson CJ, Gaudron, Gummow and Hayne JJ in Western Australia v Ward (2002) 213 CLR 1 (Ward)(at [321]) (footnotes omitted) was:
[321] Were it not for the special provisions of s 45 of the NTA, s 10 of the RDA would ensure that the amount of compensation would be that determined in accordance with s 123 of the WA Mining Act. Section 45 is an instance of the operation of s 7 of the NTA to control the interrelation between the NTA and the RDA. Section 45(1) states:
"If the [RDA] has the effect that compensation is payable to native title holders in respect of an act that validly affects native title to any extent, the compensation, in so far as it relates to the effect on native title, is to be determined in accordance with section 50 as if the entitlement arose under this Act."
Section 50 is in Div 5 of Pt 2 of the NTA, which is headed "Determination of compensation for acts affecting native title etc". Section 50(1) states:
"A determination of the compensation may only be made in accordance with this Division."
It should be emphasised that when the RDA operates in this way, the validity of the grants of the mining leases is unaffected, as is the extinguishing effect that those grants may have on any native title. The grants did not, therefore, constitute category C past acts. The result is that to the extent that the grants of the respective mining leases extinguished native title, that native title is extinguished and in place thereof, the holders of that native title have a statutory entitlement to compensation as described above.
