Part 2 · The people

The Constitution never mentions citizenship. Membership of the Australian polity runs through constitutional categories that statute informs but cannot fix, and the gap between the two is where this topic lives. Love sits in that gap, and so do the marks.

Three ideas the topic makes you separate

Everything in this module follows from one omission: the Constitution contains no mention of citizenship. Formal membership is worked out through the constitutional categories "subjects of the Queen" and "people of the Commonwealth" in ss 7 and 24, and through the naturalization and aliens power in s 51(xix), with statute filling the space between them (Arcioni). Because the framework has three moving parts, the first task in any answer is to keep them apart.

RULE. keyringThree distinct concepts unlock the topic: 1. citizenship, a statutory status; 2. constitutional membership, the "people of the Commonwealth" in ss 7 and 24; 3. alienage, the constitutional concept in s 51(xix). Statute informs the constitutional concepts. It cannot conclusively define them.
Trap. Citizenship is not constitutional membership, and treating them as one misses the point of Love. The whole case is about a person who is not a citizen under the Act yet is not an alien under the Constitution. If your analysis cannot describe that person, it has collapsed the categories.

Citizenship as a statutory creature

Australian citizenship is young. It dates only from the Nationality and Citizenship Act 1948, in force on 26 January 1949; before that, Australians were British subjects, which is why the Constitution's own vocabulary speaks of "subjects of the Queen" rather than citizens. The framers wrote membership in imperial terms, and the statutory status arrived half a century later to fill a space the text had left open.

Because the status is statutory, Parliament largely controls it, and Arcioni observes that the High Court "defers to the Parliament's determination of membership". The deference is real, and two cases show its reach. Pochi v MacPhee holds that only formal naturalization takes up allegiance, so decades of residence in Australia do not do it: a long-term resident who never naturalises remains an alien for constitutional purposes. Ame holds that citizenship can be removed even by delegated legislation, which is about as complete a statement of parliamentary control as the doctrine offers.

But the deference has a floor, and the floor is constitutional. Parliament defines citizenship; it does not define alienage. The open limit, stated in Pochi and carried through the modern cases, is that Parliament "cannot treat someone as an alien who is not 'truly' an alien". For most of a century that limit looked theoretical. Love made it bite.

RULE. arrowParliament determines citizenship by statute and the courts defer to that determination, but Parliament cannot treat someone as an alien who is not truly an alien (Pochi v MacPhee; Arcioni).

Love and Thoms: the gap made visible

In Love v Commonwealth; Thoms v Commonwealth the High Court held, 4:3, that Aboriginal Australians who satisfy the tripartite Mabo test are not within the aliens power, even if they are not citizens. Both men were born overseas, held foreign citizenship, and faced deportation after criminal convictions, which put the question squarely: could the Commonwealth treat them as aliens because the statute did not make them citizens? The majority answered no, and the reasoning turns on the meaning of alienage itself. An alien is a person "belonging to another place", and, in Gordon J's words, "an Aboriginal Australian cannot be said to belong to another place". The constitutional concept, not the statutory status, controlled the outcome.

RULE. checklistThe tripartite Mabo test: 1. descent; 2. self-identification; 3. recognition by traditional authority. A person who satisfies all three is outside the aliens power in s 51(xix), whatever their statutory citizenship (Love; Thoms).

Gordon J grounds the result in what she calls the "deeper truth" recognised in Mabo: the unique spiritual connection between Aboriginal people and land and waters, recognised by the common law, has constitutional consequence, and it is "not extinguished by the grant or acquisition of foreign citizenship". That framing matters for essays, because it makes Love a case about what the common law's recognition of connection to country implies for membership of the polity, not a case about immigration policy.

The dissents deserve equal attention, because a fragile majority is only as safe as the answers to them. The first dissenting argument is definitional: alienage should simply track statutory non-citizenship, so that a person Parliament has not made a citizen is an alien, full stop. That reading restores clean parliamentary control and avoids a race-based constitutional category. The second is institutional: because the third limb of the tripartite test turns on recognition by traditional authority, the majority's rule hands elders a constitutional gatekeeping role, deciding who is beyond the reach of a head of Commonwealth power. Whether that is objectionable or simply the consequence of taking Mabo seriously is exactly the evaluative question a strong answer confronts.

Trap. Status check: Love is good law but precedentially fragile, so argue it both ways. The decision was 4:3 with no single ratio. The attempt to reopen it in Montgomery was discontinued in 2022, and the bench has changed. The dissents are powerful: alienage tracks statutory non-citizenship, and the tripartite test hands traditional authorities a constitutional gatekeeping role. A problem answer applies Love, then flags exactly this.

Belonging beyond the statute

The doctrinal material sits inside a larger argument about what membership is, and the examiners reward answers that can move between the doctrine and the argument. Kwaymullina offers a relationship-based citizenship: belonging through kin, country and obligation, set against the statist model of formal status conferred from above. On this account Love looks less like an anomaly and more like the Constitution catching up with an older form of membership. On the statist account it looks like the Court inventing a category the text does not contain. Knowing both readings lets you use the same case for opposite essays.

International law presses on the statist model from the other side. The 1961 Convention on the Reduction of Statelessness obliges parties to grant nationality, for example by birth on territory, and to restrict deprivation of nationality where the person would be rendered stateless. The Convention matters in an exam for two reasons: it shows that even on the statist model, states do not have an entirely free hand in defining membership, and it supplies the limiting case for grand claims about state membership. The claim, made by Morris, that virtually everyone in the modern world is the subject of a state meets its limit in statelessness itself, and in Indigenous accounts of belonging that precede and survive the state.

RULE. compassChoose your frame before you argue: the statist model (membership is status conferred from above by law) or relationship-based belonging (membership grows from kin, country and obligation). The frame you pick decides what Love proves.

The method that earns the marks

Attack plan. Four steps, in this order. 1. Separate the three ideas: statutory citizenship, constitutional membership under ss 7 and 24, and alienage under s 51(xix). 2. Place the person: citizen or not, and inside or outside the aliens power. 3. If a non-citizen Aboriginal person appears, apply Love through the tripartite test, then flag the dissents, the missing ratio and the changed bench. 4. Evaluate: weigh the statist model against relationship-based belonging, and say which you prefer and why.

Worked example

Tom was born in New Zealand and holds New Zealand citizenship. He is a descendant of a recognised Aboriginal people, identifies as such, and is recognised by the elders of that people. After serving a prison sentence, he faces deportation as an "alien". Advise.

A Pass answer says. Tom is not an Australian citizen, but under Love v Commonwealth Aboriginal Australians are not aliens, so he cannot be deported. This reaches the likely result but skips the structure that earns the marks: it never separates citizenship from alienage, never applies the tripartite test to the facts, and treats a 4:3 decision with no single ratio as if it were settled.

An H1 answer says. Tom is not a citizen under the Act, but citizenship is statutory while alienage is constitutional, and Parliament cannot treat someone as an alien who is not truly an alien (Pochi). On the facts Tom satisfies each limb of the tripartite Mabo test: descent, self-identification, and recognition by traditional authority. Applying Love, he is outside s 51(xix) because "an Aboriginal Australian cannot be said to belong to another place" (Gordon J), and his New Zealand citizenship does not extinguish the connection. The answer then flags the fragility honestly: 4:3, no single ratio, Montgomery discontinued, a changed bench, and dissents that read alienage as statutory non-citizenship. It advises that Tom should succeed on current authority, while identifying the argument the Commonwealth would run to reopen it.

Critical pitfalls and counter-arguments

Take it to the practice bank

This topic runs both ways in the exam: Love problems with a non-citizen Aboriginal person, and essays on membership and belonging. In the Principles of Public Law practice bank, the membership problems are drilled with a realistic Pass answer, an H1 model answer and the examiner's comments.

Practice prompts

  1. Write the Love paragraph for a problem answer: the rule in one sentence, the tripartite test applied limb by limb, and the fragility flagged in two sentences that do not undermine your conclusion.
  2. Draft the strongest version of the dissents' position, that alienage simply tracks statutory non-citizenship, then answer it using Pochi's open limit and Gordon J's deeper truth.
  3. Write one paragraph using Kwaymullina to reframe the whole topic: what does membership look like if it grows from kin, country and obligation rather than from a statute, and what follows for the statist model?
