Love v Commonwealth (Australia, 2020): The Constitutional Limits of the “Alien” Concept

Love v Commonwealth (Australia, 2020): The Constitutional Limits of the “Alien” Concept

Can an Indigenous person be an “alien” even without citizenship?


Love v Commonwealth (Australia, 2020): The Constitutional Limits of the “Alien” Concept

Love v Commonwealth is one of the most controversial recent decisions in Australian constitutional law. It is not merely an immigration/deportation case; it asks a more foundational question—how far the constitutional concept of “alien” can extend. In particular, the case squarely confronted whether Aboriginal Australians can fall within the Constitution’s category of “aliens” even if they do not hold Australian citizenship. For that reason, the dispute links not only to legal doctrine, but also to history, identity, and constitutional order. The High Court resolved the issue by the narrowest majority, and the decision has continued to reverberate across migration law and constitutional interpretation. Today, I will set out the Court’s reasoning structure and a safe way to organize it for exams and reports, step by step.

Case background: Indigenous persons facing deportation

Love v Commonwealth considered together the cases of two Indigenous men, Daniel Love and Brendan Thoms. Although both were born in or grew up in Australia, neither held Australian citizenship. After being convicted of serious offences, they were classified under migration law as “aliens” and became liable to deportation.

The difficulty was that, while they were not citizens as a matter of statutory status, they were Aboriginal Australians. The Minister treated them as foreigners because they lacked citizenship, but the plaintiffs argued that “an Aboriginal person cannot be an ‘alien’ under the Constitution.”

That moved the dispute beyond ordinary deportation validity and into a deeper constitutional question: who counts as a “member” of the Australian political community presupposed by the Constitution?

Constitutional issue: The meaning of “alien”

Section 51(xxvii) of the Australian Constitution gives the Commonwealth Parliament power to legislate with respect to “aliens”. Traditionally, “alien” has been understood as a non-citizen; on that approach, Love and Thoms would fall within the deportation power.

Standard Contested point
Citizenship-based Can Parliament define the concept entirely?
Constitutional concept Is there a constitutional limit on legislation?

So the question narrowed to this: not “is a non-citizen always an alien?”, but can Aboriginal Australians fall within the constitutional category of ‘aliens’?

The Court’s reasoning: Indigenous status and the Constitution

The majority held that “alien” is not a purely statutory label determined only by citizenship status; rather, it is a constitutional concept with internal limits. A central theme was that Aboriginal Australians have a unique relationship with the land that predates the Australian state itself.

  • Aboriginal Australians are foundational members of the Australian community
  • A constitutional status that does not depend on citizenship
  • Setting a constitutional boundary on the aliens power

To identify who qualifies as Aboriginal for this purpose, the High Court relied on the Mabo test (descent, self-identification, and community recognition).

Outcome and majority/dissent

By a narrow 4:3 majority, the High Court held that Love and Thoms were not “aliens” for constitutional purposes. Their deportation under migration law therefore exceeded the scope of s 51(xxvii) and was invalid.

The majority’s core reasoning was that Aboriginal Australians are, independently of citizenship law, constitutional members of the Australian community who precede the polity, and therefore cannot be classified as “foreigners.” This reasoning also implies that Parliament cannot define “who is an alien” entirely through citizenship legislation.

Majority Dissent
Aboriginal Australians are not aliens If you lack citizenship, you are an alien
Internal limits within a constitutional concept Deference to legislative choice
Mabo criteria applied Criticizes judicial expansion of the concept

Significance: Constitutional boundaries on the migration power

The major significance of Love v Commonwealth is that it made clear the aliens power in s 51(xxvii) is not unlimited. In particular, by accepting that statutory citizenship cannot fully explain constitutional belonging, the Court imposed a significant structural constraint on the migration framework.

The decision is also important because it frames Indigenous constitutional status not as a “list of rights,” but as a question of belonging and identity. At the same time, the sharp split between majority and dissent has led to ongoing debate about doctrinal stability and the possibility of future reconsideration.

Exam/assignment key points

  • Love = a citizenship case ❌ / constitutional limits on the “alien” concept ⭕
  • Mention the Mabo criteria (descent, self-identification, community recognition)
  • 4:3 split majority → stability/overruling discussion point

Frequently Asked Questions (Love v Commonwealth)

Did Love grant citizenship to Aboriginal Australians?

No. The High Court did not confer citizenship. It held only that Aboriginal Australians, regardless of citizenship status, cannot be “aliens” for constitutional purposes.

Does that mean Aboriginal Australians can never be deported?

Deportation as an “alien” under migration law is not available, but that does not immunize a person from criminal punishment or other legal consequences. The decision is confined to the scope of the migration/aliens power.

Why didn’t the Court simply use citizenship as the test?

The majority reasoned that if “alien” were purely statutory, constitutional limits would disappear. It therefore treated “alien” as a constitutional concept with its own boundaries.

Why does the Mabo test appear here?

The Court needed an established, workable standard to identify Aboriginality. It adopted the existing Mabo test: descent, self-identification, and community recognition.

Is this connected to Roach or Lange?

The doctrines are different, but they share a family resemblance: each derives constitutional limits from concepts not expressly set out as “rights,” grounding them in constitutional structure.

What is the riskiest way to describe Love in an exam?

Describing it as a “citizenship case for Indigenous people.” The accurate framing is constitutional limits on the concept of ‘alien’.

In closing: How far can the Constitution determine “who is an alien”?

Love v Commonwealth is not simply a case about deportation; it is a case that vividly shows how the Constitution draws the relationship between the individual and the state. The majority spoke in terms of a deeper form of “belonging” than administrative citizenship status, and held that Aboriginal Australians cannot be fitted into the category of “foreigners” because they are part of the Australian community in a foundational sense. At the same time, because the decision rests on a very narrow majority, it leaves an open question about doctrinal stability. In that sense, Love is less a final endpoint than a marker showing where the boundaries of constitutional concepts might lie. For exams and reports, the most accurate approach is to focus on the structural point—“constitutional limits on the aliens power”—rather than treating the decision as an emotive statement about citizenship.
