Mabo v Queensland [No 2] is a landmark decision. The High Court held, by a six to one majority, that the common law of Australia recognises a form of native land title which survived the Crown's acquisition of sovereignty over Australia. The effect of the Crown's acquisition of sovereignty, according to the High Court, was simply to expose common law native title to the possibility of extinguishment by a valid exercise of inconsistent sovereign power.
The judgments in Mabo [No 2] range widely across issues of constitutional law and the law of real property. These issues are explored below in a description and analysis of the case. In addition, mention is made of the techniques of legal reasoning adopted by the majority judges.
1 (1992) 175 CLR I.
2 That judges make law is, of course, no revelation. See, for example, M McHugh, “The Law-making Function of the Judicial Process” (1988) 62 AL.I 15-31 (Pt I)and 116-127 (Pt II). What was notable about the judicial role in Mabo [No 2] was the openness with which this law-making function was assumed, and the fact that the new legal rule fonnulated by the Court represented a dramatic departure from the previous legal position.

34 Id. Deane and Gaudron JJ expressed themselves in- slightly different terms. They agreed with Brennan J that the rights attaching to common law native title would be lost “by the abandonment of the connexion with the land or by the extinction of the relevant tribe or group”. However, they added that such rights would not necessarily be lost by the abandonment of traditional customs and ways “at least where the relevant tribe or group continues to occupy or use the land”. See ibid 110. Toohey J denied that the modification of traditional society entailed the extinction of traditional title. In his Honour's opinion: “[T]raditional title arises from the fact of occupation, not the occupation of a particular kind of society or way of life. So long as occupation by a traditional society is established now and at the time of annexation, traditional rights exist. An indigenous society cannot, as it were, surrender its rights by modifying its way oflife”. See ibid 192.
