1. The common law of Australia rejects the proposition that, when the
Crown acquired sovereignty over territory which is now part of
Australia, it thereby acquired the universal and absolute beneficial
ownership of all the land therein.
2. The common law accepts that the antecedent rights and interests in
land possessed by the indigenous inhabitants of the territory survived
the change in sovereignty; and those antecedent rights and interests
thus constitute a burden on the radical title of the Crown. (Radical
title is a title adapted from feudal theory that was called a radical,
ultimate or final title).
3. The theory of terra nullius (a territory belonging to no-one) is
rejected by the common law of Australia.
4. The Crown's acquisition of sovereignty over the several parts of
Australia cannot be challenged in an Australian municipal court.
5. The common law of Australia recognizes a form of native title
which, in the cases where it has not been extinguished, reflects the
entitlement of the indigenous inhabitants, in accordance with their laws
or customs, to their traditional lands.
6. Native title to land survived the Crown's acquisition of
sovereignty and radical title. The rights and privileges conferred by
native title were unaffected by the Crown's acquisition of radical
title, but the acquisition of sovereignty exposed native title to
extinguishment by a valid exercise of sovereign power inconsistent with
the continued right to enjoy native title.
7. Where the Crown has validly alienated land by granting an interest
that is wholly or partially inconsistent with a continuing right to
enjoy native title, native title is extinguished to the extent of the
inconsistency. Thus native title has been extinguished, for example, by
grants of estates of freehold, but not necessarily by the grant of
lesser interests (eg. authorities to prospect for minerals).
8. Where the Crown has validly and effectively appropriated land to
itself and the appropriation is wholly or partially inconsistent with a
continuing right to enjoy native title, native title is extinguished to
the extent of the inconsistency. Thus native title to parcels of the
waste lands of the Crown that have been validly appropriated (whether by
dedication, setting aside, reservation or other valid means) and used
for roads, railways, post offices and other permanent public works which
preclude the continuing concurrent enjoyment of native title, has been
extinguished. Native title continues where the waste lands of the Crown
have not been so appropriated or used or where the appropriation and use
is consistent with the continuing concurrent enjoyment of native title
over the land (eg. land set aside as a national park).
9. Extinguishment of native title by the Crown by inconsistent grant
does not give rise to a claim for compensatory damages, at least to the
extent of the inconsistency. The refinements of this principle remain
to be determined.
10. Native title to particular land, its incidents and the persons
entitled thereto are ascertained according to the laws and customs of
the indigenous people who, by those laws and customs, have a connection
with the land. It is immaterial that the laws and customs have
undergone some change since the Crown acquired sovereignty, provided the
general nature of the connection between the indigenous people and the
land remains. Membership of the indigenous people depends on biological
descent from the indigenous people and on mutual recognition of a
particular person's membership by that person and by the elders or other
persons enjoying traditional authority among those people.
11. Native title to an area of land which a clan or group is entitled
to enjoy under the laws and customs of an indigenous people is
extinguished (a) if the clan or group, by ceasing to acknowledge those
laws and (so far as practicable) observe those customs, loses its
connection with the land or (b) on the death of the last of the members
of the clan or group.
12. Native title over any parcel of land can be surrendered to the
Crown voluntarily by all those clans or groups who, by the traditional
laws and customs of the indigenous people, have a relevant connection
with the land, but the rights and privileges conferred by native title
are otherwise inalienable to persons who are not members of the
indigenous people, to whom alienation is permitted by the traditional
laws and customs.
13. If native title to any parcel of the waste lands of the Crown is
extinguished, the Crown becomes the absolute beneficial owner.
14. The question of the validity of any purported exercise by the
Crown of the power to alienate or to appropriate to itself waste lands
of the Crown is left for resolution by the general law.
15. The power of alienation and the power of appropriation vested in
the Crown in right of a State are also subject to the valid laws of the
Commonwealth, including the Racial Discrimination Act. Where a power
has purportedly been exercised as a prerogative power, the validity of
the exercise depends on the scope of the prerogative and the authority
of the purported repository in the particular case.
