Recently a number of Australian members of the federal parliament have been referred to the high court because they might have a foreign citizenship. The first was a simple oversight by the politician in question, but the rest start to get a little obscure.

My understanding is that if a person has a citizenship of a foreign country they cannot serve as a member of federal parliament. The catch is there appears to be no requirement for the person who is a citizen to have used it at some stage or even have known they applied for it. For example, Senator Matt Canavan became a citizen of Italy because his mother applied for it without his knowledge.

So, with this background, could a foreign government mess around with the Australian parliament by giving citizenship to the federal members of parliament? Could North Korea give Malcolm Turnbull (Current Australian Prime Minister as of 2017) citizenship as a way to disrupt the parliament?

What does the law say? How could it be interpreted?

The law is not settled and will shortly be before the High Court (sitting as the Court of Disputed Returns) but theoretically: yes!

The provision on Disqualification is s44, specifically subsection (i):

Any person who:

(i) is under any acknowledgment of allegiance, obedience, or adherence to a foreign power, or is a subject or a citizen or entitled to the rights or privileges of a subject or a citizen of a foreign power,

shall be incapable of being chosen or of sitting as a senator or a member of the House of Representatives.

Which, on the face of it, makes eligibility to sit in the Australian parliament dependent on the citizenship laws of every other country in the world: all 195 of them.

Indeed, right now, any citizen of Australia (which is itself a qualification by virtue of s16 or s34), is allowed to live and work in New Zealand, and to vote after a year's residence - that is they are "entitled to the rights or privileges of a subject [but not a citizen] of a foreign power".

Therefore, interpreted that way, no Australian is entitled to sit in parliament. Of course, a simple referendum1 could change the Constitution to fix that - except, a referendum must be called by parliament and we no longer have one.

Personally, I think it is unlikely2 that the High Court will rule in such a way that would plunge the nation into a constitutional crises by deciding no one can sit in parliament or that who can sit is determined by the laws of foreign nations.

Notwithstanding, at present there are 5 MPs who have been referred to the High Court (2 of whom have already resigned), 2 more who will be referred when parliament resumes in September, 21 known to have been born overseas who have not confirmed that they have renounced any foreign citizenship they might have and an unknown number who may have foreign citizenship by descent.

Each of the cases is distinct: some were born overseas, some have foreign citizenship by descent, one is a 3rd generation Australian whose mother registered him as an Italian citizen when he was a child (17) and he claims he never knew. How the High Court will rule will almost certainly vary with the particular circumstances but its anyone's guess what they will decide. However, it appears that the drafters of the constitution intended that it should capture all dual-citizens, not just those who sought dual-citizenship by a deliberative act.

If a person is found to be ineligible then different things happen depending on if they ware a Senator or a Member of the House of Representatives. For a Senator, the High Court would recount the results of the election - because of the strange way voting works for the Senate, only educated guesses can be made about who would replace whom (especially since the same citizen issue may apply to other candidates on the ticket). For a Member of the House of Representatives, a by-election would be held - because the Liberal/National government has a majority of 1 and 3 of their members are in the gun the results will be ... interesting.

1 Referenda in Australia are not simple. The Australian Constitution is specifically designed to be difficult to change while at the same time granting broad powers to parliament. It takes a nationwide vote and must be carried by a majority of voters nationwide and a majority in a majority of the six states (i.e. 4 or more). Since federation in 1901 there have been 44 referenda of which only 8 have been carried. In is generally accepted that a referendum is impossible to pass unless it has bi-partisan support: and sometimes not even then.

2 And by "unlikely" I mean "impossible" - a conclusion that the constitution must be read in such a way that parliamentary democracy becomes impossible would be contrary to law.

Update in light of the High Court’s ruling: No

Providing a potential parliamentarian has taken “all reasonable steps” to renounce foreign allegiance they are permitted to serve even if the foreign power refuses to allow them to renounce citizenship.

In practice, this means writing to the foreign embassy and renouncing citizenship.

  • Based on the results of the case and the ruling for mark canavan would the answer be no or is it still ambigious Oct 30, 2017 at 23:52

    I wonder what would happen if another country passed a law saying that anyone elected to the Australian parliament is automatically a citizen of that country.

    1) I don't think New Zealand does "have essentially the same provision"; could you provide a reference for that? 2) Australian citizens are allowed to vote in New Zealand elections, as long as they have lived there for a year first. Jun 30, 2018 at 0:15
  • Isn't that senate election system just STV, Single transferable vote? That's what the description there looks, and what Wikipedia says (in the sidebar).

I strongly suspect that the answer is that no, this would not work.

The validity of the additional grant of citizenship would be evaluated by an Australian court applying Australian law. One of the underlying principles of that body of law is that gifts must be accepted and can be disclaimed. Another is that an adult's legal status cannot normally be changed without that adult's consent or with due process.

Therefore, the situation you propose would probably not qualify as a valid grant of citizenship for Australian legal purposes unless it was voluntarily accepted by the legislator in question, or by someone with the legal authority to act on that legislator's behalf at the time the citizenship was granted.

    "The validity of the additional grant of citizenship would be evaluated by an Australian court applying Australian law" But Australian law doesn't currently say anything about who has or doesn't have another country's nationality, or in which cases it would recognize or not recognize a person's foreign nationality. So I don't see how you can "apply Australian law" to this.

    Australian law would determine what acts constitute acquisition of foreign citizenship for purposes of the Australian constitution. Another country's statement would be one fact that could be considered in that determination, but not the only one. Dual citizenship exists at all mostly because there is not consistency in how different countries treat the concept of citizenship.

  • "Australian law would determine what acts constitute acquisition of foreign citizenship for purposes of the Australian constitution." But Australian law and constitution currently doesn't say anything about "what acts constitute acquisition of foreign citizenship for purposes of the Australian constitution"

    "Dual citizenship exists at all mostly because there is not consistency in how different countries treat the concept of citizenship." It exists because who is each country's national is solely determined by the law of that country, and each country's law is independent. It is true that a country can still choose to recognize or not recognize a person's foreign nationality that that foreign country says he/she has, but again Australian law doesn't currently have any guidelines for this.

    @user102008 Just because Australian law or its constitution doesn't have statutes on point does not mean that there is no Australian law on the topic. As a common law country, Australia has many centuries of Australian and English case law to which it can resort which provide guidance of some sort on every legal question which I allude to in my answer.

From an opinion piece published by the public broadcaster Australian Broadcasting Corporation What the High Court citizenship decision says about the health of our democracy

The standard is a strict one: It is no excuse, for the purposes of section 44, that an MP has no real ties to a foreign power, or did not in fact know they were a citizen of another country.

But it is not a wholly absolute one: the court recognises foreign countries cannot make it impossible, or unreasonably onerous, to renounce allegiance to that country. To allow this, the court held, would impermissibly undermine "the constitutional imperative that an[y] Australian citizen" be able to participate in representative government.

If a foreign government was trying to deny an Australian citizen the ability to be a MP, their dual citizenship would likely not be in contravention of section 44 of the constitution.
