Mabo v Queensland (No 2) [1992]

(1992) 175 CLR 1 · High Court of Australia · Australia

African Customary LawAfrican Customary LawIndigenous Legal SystemsConstitutional Law

Issue

Whether the common law doctrine of terra nullius applied in Australia and whether indigenous native title could survive the Crown's acquisition of sovereignty.

Held

The common law of Australia recognises a form of native title that reflects the entitlement of indigenous inhabitants to their traditional lands. The doctrine of terra nullius was wrongly applied.

Exam use

Compare with African customary land tenure cases (e.g., Amodu Tijani v Secretary, Southern Nigeria). Note the tension between communal customary title and individual freehold systems.

Summary

Overturned 200 years of Australian land law based on terra nullius; established the Native Title Act framework; profoundly influenced indigenous land rights discourse globally, including in Africa.

Facts

Eddie Mabo and fellow Meriam people claimed native title to the Murray Islands in the Torres Strait. The State of Queensland argued that Australia was terra nullius at colonisation, extinguishing any prior indigenous rights.

Procedural History

Action commenced in the High Court in 1982; Queensland sought to defeat the claim by enacting the Queensland Coast Islands Declaratory Act 1985, which was struck down in Mabo (No 1).

Issue

Whether the common law doctrine of terra nullius applied in Australia and whether indigenous native title could survive the Crown's acquisition of sovereignty.

Held

The common law of Australia recognises a form of native title that reflects the entitlement of indigenous inhabitants to their traditional lands. The doctrine of terra nullius was wrongly applied.

Ratio Decidendi

Native title is recognised at common law when the claimants can demonstrate a continuous connection to the land under traditional laws and customs, and the title has not been extinguished by a valid legislative or executive act.

Reasoning

Brennan J (majority) held that the common law must evolve to reflect contemporary values; the fiction of terra nullius unjustly denied indigenous peoples their pre-existing rights. The Crown's radical title did not automatically extinguish native title; extinguishment required clear statutory or executive intent.

Plain-English Explanation

This case decided that indigenous people who had lived on land according to their own laws before Europeans arrived still had legal rights to that land after colonisation, unless the government had specifically taken it away.

Version 1 of 4

Reference to Mabo v Queensland (No 2) ((1992) 175 CLR 1) strengthens a African Customary Law answer because the case reflects the principle that Native title is recognised at common law when the claimants can demonstrate a continuous connection to the land under traditional laws and customs, and the title has not been extinguished by a valid legislative or executive act. Applied to a problem question, the case should be used after identifying the issue as Whether the common law doctrine of terra nullius applied in Australia and whether indigenous native title could survive the Crown's acquisition of sovereignty. The stronger essay move is to connect the material facts to the court's holding, then explain whether the present facts support the same conclusion or justify distinguishing the authority.
