Legal requirements

The Australian Constitution does not require candidates for the Commonwealth Parliament to hold Australian citizenship (which did not come into existence until 1949), but this is now required by the Commonwealth Electoral Act 1918 as amended.^[17] Members must not owe allegiance to any other country, including holding a foreign citizenship. Section 44(i) of the Constitution states:

44. Any person who –

(i.) Is under any acknowledgement 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 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.^[18][19]

Earlier challenges and High Court interpretation

Section 44(i) has generally been interpreted by the High Court of Australia as meaning that persons with dual citizenship are not permitted to stand for election and that a person must take "reasonable steps" to renounce their citizenship of the other country.^[20] The section has rarely been invoked before.

In 1990, George Turner, a Sydney-based barrister and independent Senate candidate, threatened High Court action against federal parliamentarians holding dual citizenship. As a result, The Canberra Times reported that at least nine MPs elected at the 1987 federal election had renounced foreign citizenships.^[21]

In Sykes v Cleary (1992), a candidate who had been declared elected in a by-election was found ineligible under Section 44(iv) of the Constitution. The High Court ruled that both of the candidates who were likely to have been elected by a countback were ineligible under s 44(i). When they had become Australian citizens, they had renounced all foreign nationality (as Australian law then required), but they had not attempted to renounce under the law of their home countries and therefore were still subjects of a foreign power. They should have taken at least "reasonable steps" to do that, before nominating. "Reasonable steps" for any future candidate would depend on the individual circumstances.^[22] In 1999, in Sue v Hill, the High Court found that a British citizen who had been declared elected to the Senate in 1998 was disqualified under s 44(i). Although the UK had not been a "foreign power" in 1901, it had been since at least the Australia Act 1986.^[23]

Earlier application of section 44 in the 45th Parliament

Former Senator Bob Day (left) and his replacement Lucy Gichuhi (right), who faced citizenship questions based on her Kenyan background. The High Court found that she was not a dual citizen and was free to take her seat in the Senate.

The prelude to the crisis began when Bob Day of the Family First Party resigned from the Senate on 1 November 2016 following the collapse of his business. Shortly after Day's resignation, the Senate referred to the High Court the validity of Day's election in July 2016 for a possible breach of section 44(v) of the Constitution. It provides that

a person who "has any direct or indirect pecuniary interest in any agreement with the Public Service of the Commonwealth ... shall be incapable of being chosen or of sitting" as a member of Parliament.^[24]

The basis of the complaint was that Day's Commonwealth-funded electorate office was leasing part of a building in Adelaide which he indirectly owned. The Commonwealth's payments of rent for the office would eventually come into a bank account of his own.^[25][26] In April 2017, the court found that Day was not validly elected at the 2016 election and ordered that a special count of South Australian ballot papers be held to determine his replacement.^[27] The court announced that Lucy Gichuhi was elected in his place. The Australian Labor Party lodged a challenge, claiming that Gichuhi might still be a citizen of Kenya, hence ineligible under Constitution section 44(i) as a citizen of a "foreign power". On 19 April 2017 a full court of the High Court found that the objection had not been proven and declared Gichuhi elected.^[28][29]

Senator Rodney Culleton, who had left Pauline Hanson's One Nation on 19 December 2016 to become an independent, had his eligibility to stand in the 2016 election challenged on two constitutional grounds. Among the grounds of ineligibility provided in Section 44, a person cannot sit in either house of the Parliament if they are bankrupt or have been convicted of a criminal offence carrying a potential prison sentence of one year or more.^[24] Culleton was declared bankrupt by the Federal Court on 23 December 2016. On 11 January 2017, after receiving an official copy of the judgment, the President of the Senate declared Culleton's seat vacant. Culleton's appeal against that judgment was dismissed by a full court of the Federal Court on 3 February 2017.^[30]

This judgment was followed later on the same day by the High Court's decision that Culleton was ineligible owing to conviction for a criminal offence carrying a potential prison sentence of one year or more. This was a decision as the Court of Disputed Returns following a reference by the Senate at the same time as with Day. It was decided that Culleton's possibility of a two-year sentence for larceny that had been in place at the time of the 2016 election rendered him ineligible for election, and that this was not affected by the subsequent annulment of that conviction. The court also held that the resulting vacancy should be filled by a countback of the ballots, in a manner to be determined by a single Justice of the Court.^[31] Following that count, on 10 March 2017, the High Court named Peter Georgiou as his replacement, returning One Nation to 4 seats.^[32]

Procedure

The Commonwealth Constitution provides the High Court with original and appellate jurisdiction, and also empowers the Commonwealth parliament to provide additional original jurisdiction.^[33] The parliament is also empowered to provide that questions of members' eligibility, of vacancies in either house and that disputed elections shall be determined other than by the relevant house, the position inherited from the Parliament of the United Kingdom.^[34] In exercise of these powers, the Commonwealth Electoral Act 1918, which governs federal elections, provides the High Court with a jurisdiction as the federal Court of Disputed Returns.^[35]

Parliamentarians alleged to have dual citizenship

Scott Ludlam

Scott Ludlam's (left) resignation from parliament and subsequent investigation sparked similar discoveries for many fellow elected parliamentarians, including fellow Senator Larissa Waters (right).

Scott Ludlam had been a Greens senator for Western Australia since 1 July 2008.

On 14 July 2017, Ludlam announced that he still retained New Zealand citizenship from his birth in New Zealand, and consequently would be resigning from parliament.^[51] Ludlam with his family had settled in Australia aged eight, and had previously assumed he lost his New Zealand citizenship when he naturalised as an Australian citizen in his mid-teens.^[124] Since Ludlam was ultimately found to have been ineligible to be elected, his seat was filled by a countback of the 2016 federal election in Western Australia, resulting in Jordon Steele-John, the next un-elected Greens candidate on the Senate ticket in Western Australia, winning the seat. Steele-John is a 23-year-old disability rights advocate, who is Australia's youngest senator in history.^[125]

As of 8 October 2017, Ludlam has not renounced his New Zealand citizenship and has no immediate plans to return to politics.^[126]

Barnaby Joyce

Both the leader and the deputy leader of the Nationals, MP Barnaby Joyce (left) and Senator Fiona Nash (right), have been involved in the crisis after discovering they hold dual citizenship.

Barnaby Joyce had been a National Party member of the House of Representatives seat of New England, New South Wales since 7 September 2013. Previously, he was a senator for Queensland from 1 July 2005. He had been a Minister since 18 September 2013, and Deputy Prime Minister since 18 February 2016.

On 14 August 2017, Joyce announced that the New Zealand government had informed him that he might be a citizen of New Zealand by descent from his father, saying that he was "shocked to receive this information".^{[59]: p. 1, 37–39, 53–55, 57–59, 62–67} At his request, the government moved in the House of Representatives that Joyce's position be referred to the High Court as the Court of Disputed Returns, which was carried with all-party support.^[60] Prime Minister Malcolm Turnbull stated that legal advice from the Solicitor-General confirmed Joyce's eligibility, but refused to release that advice or to say how it may have distinguished Joyce's position from that of Canavan.

Joyce renounced his New Zealand citizenship effective 15 August and produced documentary evidence of having done so.^[149] He did not resign from his ministerial offices and continued to vote in Parliament. It was reported that two leading experts on constitutional law did not share the government's total confidence about Joyce's eligibility.^[150]

The High Court permitted Tony Windsor, the independent former MP who was defeated by Joyce for the Division of New England in the 2016 general election, to be joined as a "contradictor"^{[lower-alpha 6]} in the eligibility case.^[132] Windsor's lawyers, including former Solicitor-General Justin Gleeson, argued against the Attorney-General's defence of ignorance of dual citizenship. Windsor expressed interest in running against Joyce in a resultant New England by-election, although the then-Deputy Prime Minister held the seat by a comfortable margin and his re-election was considered likely.^[152] After the High Court's decision was handed down on 27 October, Windsor declared that he would not run in the resulting by-election.^[153]

In the by-election on 2 December 2017, Joyce was elected with almost two thirds of the vote and an increased majority;^[154] he took his seat on 6 December.^[155]

Nick Xenophon

Nick Xenophon, initially questioned for Greek or Cypriot citizenship, was confirmed by British authorities to be a British Overseas citizen.

Nick Xenophon was the leader of the Nick Xenophon Team and had been a Senator for South Australia since 1 July 2008.

In August 2017, he was asked whether he might have acquired Greek citizenship through his mother, born in Greece, and British or Cypriot nationality through his father, an ethnic Greek who was born in Cyprus when it was a British colony and who possessed a British passport. He stated: "I've never had, never sought, never received citizenship of another country but out of an abundance of caution I wrote to the Greek embassy and Cypriot high commission saying essentially, 'I've never been a citizen, I don't want to be, so if there's any question that I could be, I renounce any rights to be'. I don't know what else I can do in the circumstances." He added that he had not received replies to these enquiries.^[159] Later he said he had renounced Greek citizenship but, on finding he might be British, he had sought clarification from British authorities.^[160] On 19 August, he announced that British authorities had confirmed he is a British Overseas citizen, a lesser form of British nationality.^[62] He stated that he would not resign from the Parliament, but would await a High Court decision. Together with that of Nash, Xenophon's case was referred to the Court on 4 September.^[66]

On 6 October 2017, Xenophon announced he would resign from the Senate to stand for the Parliament of South Australia at the South Australian state election due in March 2018.^[161][162] He did not name a date of resignation, although he did state his intention to remain in federal parliament until the High Court ruled on whether he had been validly elected.^[163]

The High Court ruled that Xenophon's status as a British Overseas citizen did not fall within s 44(i), so that he had been validly elected.^{[6]: para 135} His resignation would create a casual vacancy, which would be filled in the usual way.^[164]

Judgment

In Re Canavan; Re Ludlam; Re Waters; Re Roberts [No 2]; Re Joyce; Re Nash; Re Xenophon (the "Citizenship Seven Case"), the High Court sat as the Court of Disputed Returns to determine the eligibility of seven parliamentarians to have been elected and to sit.^[165][166]

Because of the political implications of the outcome of the case, the Court's decision was intensely anticipated.^[167][168] In the preliminary hearing on 12 October 2017, Chief Justice Susan Kiefel observed: "It is hardly necessary to say that the Court is aware of the need to give its answers to these references with or without reasons as soon as possible. As counsel and instructing solicitors would appreciate, it is not always possible for the Court to do so immediately."^[169]

On 27 October 2017 the High Court handed down its single joint judgment.^[6][7][170] In a unanimous judgment, the Court interpreted s 44(i) according to the "ordinary and natural meaning" of its language.^{[6]: para 19} On that approach, it firstly affirmed the view taken in Sykes v Cleary that the question of eligibility is to be determined with reference to the point of nomination.^{[6]: para 3} The Court then followed the reasoning of the majority in Sykes v Cleary. It decided that the fact of citizenship was disqualifying, regardless of whether the person knew of the citizenship or engaged in any voluntary act of acquisition.^{[6]: paras 71–2} It emphasised that to hold otherwise would introduce an element of subjectivity that "would be inimical to the stability of representative government".^{[6]: para 48} It followed that each of Joyce, Ludlam, Nash, Roberts and Waters had been ineligible to be elected. However, Canavan and Xenophon had been eligible. It was determined that, under the "reasonable view" of Italian law that the Court adopted, Canavan was not a citizen of Italy.^{[6]: para 86} It was found that Xenophon was a British Overseas citizen, but that this did not give him the right to enter or reside in the United Kingdom; therefore, for the purposes of s 44(i), he was neither a citizen nor entitled to the rights and privileges of a citizen of the United Kingdom.^{[6]: paras 134–5} The Court declared the seats of the ineligible members to be vacant; it ordered that the vacancy in the House of Representatives be filled through a by-election and that the vacancies in the Senate be filled by "special counts" (recounts or countbacks) of the ballot papers in each State, subject to supervision by a Justice of the Court.^{[6]: paras 141–5}

Senate replacements

The High Court's judgment on 27 October 2017 removed Joyce, Nash and Roberts from the Parliament. Ludlam and Waters had already resigned. Two of the ousted MPs—Joyce and Nash—were members of Cabinet, requiring a rearrangement of the Second Turnbull Ministry, which took place on the same day. Canavan, who had stepped down from Cabinet pending the court's decision, returned to Cabinet upon not being found ineligible, retaking his Resources and Minister for Northern Australia portfolios, which had been temporarily held by Joyce. Prime Minister Malcolm Turnbull took on Joyce's other portfolio of Agriculture and Water Resources.^[171] Nash's roles were given to Darren Chester and Mitch Fifield as acting ministers.^[172] Nigel Scullion became the parliamentary leader of the National Party, while the position of Deputy Prime Minister remained vacant. Julie Bishop, deputy leader of the Liberal Party, served as acting prime minister when necessary.^[173]

The seats of the disqualified Senators were filled by countbacks of the 2016 Senate election results in their states of Western Australia, Queensland and New South Wales. The countback results were announced on 10 November: in Western Australia, the Greens' Scott Ludlam was to be replaced by the Greens' Jordon Steele-John; in Queensland, the Greens' Larissa Waters was to be replaced by former Australian Democrats leader and current Greens member Andrew Bartlett, One Nation's Malcolm Roberts was to be replaced by One Nation's Fraser Anning, and the Nationals' Fiona Nash was to be replaced by Liberal Hollie Hughes.^[72] However, the court delayed the appointment of Nationals' Fiona Nash's replacement Liberal Hollie Hughes due to concerns that Hughes may be ineligible under s 44(iv) of the Constitution as a holder of an office of profit under the Crown; Hughes was reappointed to the Administrative Appeals Tribunal – a role that would ordinarily disqualify her under that section – in the period following her apparent election defeat but resigned from the position prior to the recount.^[73] The question was whether her tenure of that office had overlapped with the process of the election.^[174]

Steele-John, Bartlett, and Anning were sworn in as senators on 13 November 2017;^[75] however, Anning immediately resigned from One Nation to sit as an independent.^[147] On 15 November, the High Court ruled that Hughes was not eligible to fill Nash's seat.^[82][175] Nash's seat was instead filled by another countback excluding both Nash and Hughes, which elected Liberal Jim Molan.^[84][176]

Aftermath

A writ for a by-election for 2 December in Joyce's former seat of New England was issued on the same day as the High Court's judgment.^[67] Losing this seat would cause the Coalition to lose its majority. On the following day, the National Party endorsed Joyce as its candidate.^[177] Joyce was now eligible for election, having renounced his New Zealand citizenship in August 2017.^{[178][6]: para 108}

Immediately following the decision, Prime Minister Malcolm Turnbull said that the government would consider changes to section 44 through the Joint Standing Committee on Electoral Matters or changes to "electoral laws and practices to minimise the risk of candidates being in breach" of the section. On 29 October, however, Attorney-General George Brandis ruled out constitutional change, although considering changes to electoral laws. He also criticised the decision: "We were asking the High Court to look at the section in view of its purpose and history, the High Court instead took the view that the section should be read with a very strict, almost brutal literalism." However, he added that the law was now clear and that it was a "good thing" that the decision had been unanimous.^[179] All of section 44 has already been examined extensively, particularly by a Constitutional Commission in 1988 and by a parliamentary committee in 1997, but their proposals have not been pursued.^[180][181]

According to some legal opinions, more than 100 Turnbull government decisions are vulnerable to legal challenge as a result of Joyce and Nash's dual citizenship status, with lawyers concluding there is a high likelihood that the work the pair has done over the last year will end up before the courts, because of section 64 of the constitution, which requires ministers to be members of Parliament.^[182] The court could decide, however, that the decisions are valid because they were made by a person who was "clothed with the authority of an office".^[183]

The disqualified senators and members had collected over $9 million in base salary, ministerial bonuses and other allowances over the period that they were ineligible to sit. The government could demand repayment of such amounts or it can waive repayment.^[184] In Re Culleton (No 2) (2017), for example, the government demanded repayment from Rod Culleton, after he was found to have been ineligible, as "a debt to the commonwealth", and indicated it might also seek repayment of superannuation payments, other entitlements and staff payments. There is also possibility of an action being brought under s 3 of the Common Informers (Parliamentary Disqualifications) Act 1975,^[185] which provides that any person can bring an action for a penalty against a member of parliament for sitting in Parliament while disqualified from doing so. The government had undertaken to pay the legal costs of all parties and of Tony Windsor (intervening in the Joyce case).^[186] The final legal bill paid by the government was $11.6 million.^[187] In March 2018, the government waived the debt for salaries and expenses (salaries, superannuation and electorate allowances, as well as non-salary expenses, such as, staff expenses, office expenses and travel expenses) received by the six MPs who lost their jobs as a result of dual citizenship, saying that they acted "in good faith".^[188]

Amid continuing allegations that further members of the Parliament possess dual citizenship, there have been increasing calls for a "citizenship audit" of the Parliament, as well as speculations on the Prime Minister's own future.^[189][190] The audit proposal comes from minor parties and is opposed by the two major parties, although Labor has come to support some sort of parliamentary review. Both major parties appear to have been conducting their own internal reviews. The Greens plan to propose a select committee of the Senate, to report on the eligibility of all Senate members by 27 November, and hope that a similar committee may be established in the House or, alternatively, there could be a joint committee if not a commission of inquiry.^[191]

On 6 November, Prime Minister Turnbull proposed a set of measures under which all federal politicians would be required to publicly declare their citizenship history.^[192][193] The Labor Opposition had criticisms.^{[194][195][196]} On 13 November it was reported that the Government and the Opposition had agreed to propose what media termed a "quasi-audit", modelled on the pecuniary interests register. All members of the federal parliament were required to disclose by 1 December their date and place of birth, citizenship at birth, and details of their parents and grandparents; if they were born overseas, details of their naturalisation as Australian citizens; and an account of how they have satisfied themselves that they are not dual citizens and what they have done to renounce any foreign ties of this kind. Failure to fully comply with the register, including provision of misleading information, may constitute "serious contempt" of Parliament (a criminal offence).^[78][147] This scheme was adopted on that day by the Senate^[79] and was confirmed by the House of Representatives when it next met.

The Citizenship Seven referrals to the High Court were all moved by the member's own party, consistently with parliamentary convention. On 9 November 2017, Prime Minister Turnbull threatened to break with convention and use government-party numbers to secure a referral by the House of three Labor MPs: Justine Keay, Susan Lamb and Josh Wilson.^[197] The threat was repeated by a senior minister on 12 November, despite the government having lost its majority in the House.^[198]

On 28 November 2017, Prime Minister Malcolm Turnbull asked the Commonwealth Parliament's Joint Standing Committee on Electoral Matters (JSCEM) to conduct a new inquiry into the section, including the possibility of amendment. The report was published on 17 May 2018.^[86] On 6 December 2017, the Senate asked the JSCEM to inquire into recent referrals to the High Court as Court of Disputed Returns, with a view to establishing a disclosure mechanism for the other parts of s 44, with particular attention to the cases of Culleton and Day. The report was published on 6 February 2018.^[94]

In the lead-up to the 2019 federal election, the AEC's form for nomination has been updated to ask detailed questions on whether candidates are disqualified under section 44. Three Victorian Liberal candidates,^[199] and two in New South Wales have had to withdraw based on section 44 issues.^[200]

Stephen Parry

Stephen Parry had been a Liberal senator for Tasmania since 1 July 2005, and President of the Senate since 7 July 2014. Following the High Court's judgment in the Citizenship Seven case, Parry announced on 31 October 2017 that he was seeking advice from British authorities on whether he held British citizenship by descent. Parry's father moved to Australia from the United Kingdom in the 1950s.^[68] On 1 November, Parry confirmed his dual citizenship,^[69] and resigned on 2 November.

It has been reported that Parry became aware of his possible dual citizenship status following the revelations involving Fiona Nash in August 2017, and had discussed the matter with cabinet member Mitch Fifield months earlier, who advised him not to raise those concerns publicly due to the belief that both Canavan and Joyce would be found to be eligible.^[201] Fifield was referred to the privileges committee in relation to this.^[202] On 2 November, Prime Minister and Liberal Party leader Malcolm Turnbull said that he was "disappointed" that Parry had not made the matter known "quite some time ago" to allow his election to be referred to the court simultaneously with the previous seven cases.^[203]

The Senate referred Parry's case to the High Court as the Court of Disputed Returns.^[83] A directions hearing on 8 December determined that Parry was disqualified from standing at the 2016 election and that the Senate vacancy should be filled by a special count of the 2016 votes. The countback took place on 12 December 2017.^[204] Parry's senate position was filled by Richard Colbeck, who was sworn in on 12 February 2018.^[205]

John Alexander

On 6 November, Fairfax Media reported that Liberal MP John Alexander might hold British citizenship by descent, through his British-born father who migrated from the United Kingdom to Australia in 1911 at the age of three. Alexander stated that he believed his father's British citizenship had been renounced before he was born, but that he was making enquiries about his citizenship status with British authorities.^[70][206] Meanwhile, the federal Opposition accused the government of a "protection racket" and called for Alexander's case to be referred to the High Court.^[207]

On 11 November, Alexander announced that British authorities could not find any record of renunciation by his father and indicated his intention to resign.^[74] On 13 November, Alexander resigned^[76] and the by-election was called for 16 December, the earliest date possible.^[77] Alexander immediately filed papers with the UK Home Office to renounce British citizenship^[208] and on 17 November claimed that the application had been approved, making him eligible to stand in the by-election.^[209] John Alexander won the by-election.^[210]

Jacqui Lambie

On 8 November 2017, it was reported that independent Senator Jacqui Lambie may have British citizenship by descent from her father, who migrated from Scotland to Australia as an infant. Lambie had initially said she had "no concerns" about the possibility of her being a dual citizen, with a spokeswoman stating that Lambie would provide any relevant supporting documents when required to by Parliament.^[71][211] However, she sought advice from British authorities.^[212]

On 14 November 2017, Lambie announced her resignation from the Senate after confirming she held British citizenship,^[81] and the Senate referred her case to the High Court as the Court of Disputed Returns on the same day.^[213] A directions hearing on 8 December determined that Lambie was disqualified from standing at the 2016 election and that the Senate vacancy should be filled by a special count of the 2016 votes. The countback took place on 12 December 2017.^[204] The Electoral Office indicated that Steven Martin would be elected on a countback, and Martin was sworn in on 12 February 2018.^[205] However, Martin was the Mayor and Councillor of Devonport City Council, and the question of whether this disqualifies him from serving as a senator by reason of s 44(iv) of the Constitution (holding an office of profit under the Crown) was referred to the Full Court on 13 December 2017. On 6 February 2018 the Full Court determined that Martin was not ineligible;^[214] it published its reasons on 14 March 2018.^[214]

Skye Kakoschke-Moore

Nick Xenophon Team (NXT) Senator Skye Kakoschke-Moore resigned from the Senate on 22 November 2017, after discovering that she was a British citizen by descent from her mother, who was born in Singapore while it was a British colony and had registered for right of abode in the UK.^[215] Kakoschke-Moore had been a British citizen since birth in 1985, but stated that when she was 12, the British embassy in Oman had told her father she was not eligible for a British passport.^{[85][115][216]} Kakoschke-Moore's renunciation of her British citizenship became effective on 6 December 2017.^[217]

The Senate referred Kakoschke-Moore's case to the High Court as the Court of Disputed Returns on 29 November 2017.^[87] Kakoschke-Moore sought to be reinstated in the seat on the basis that she had by then effectively renounced British citizenship,^[218] but the Court held that "the fact that Skye Kakoschke-Moore renounced her British citizenship with effect from 6 December 2017 does not render her capable of now being chosen to fill that vacancy", and that the vacancy should be filled by a special count of the votes. Kakoschke-Moore and Timothy Storer had both been nominated for the 2016 election for the Senate for South Australia as nominees of NXT. However, since the election Storer had ceased to be a member of NXT by 6 November 2017, and the question of whether Storer should be excluded from the special count for that reason was referred to the Full Court, which on 13 February 2018 ruled that Storer was not to be excluded from the countback, and who assumed the seat on 16 February 2018. The Court published its reasons on 21 March 2018.^[217]

David Feeney

Labor MP for Batman David Feeney stated in the citizenship register that his father was born in Northern Ireland, and that he was advised by the party to ensure he renounced British (and potentially Irish) citizenship before nominating. Feeney said he did so in late 2007, but conceded he was unable to produce documentation confirming the renunciation had been registered.^[219]

The House of Representatives referred Feeney's case to the High Court as the Court of Disputed Returns. During a directions hearing on 19 January 2018,^[97] Feeney was unable to submit evidence of his renunciation of citizenship, delaying court proceedings. His legal representative submitted that Feeney's renunciation was lodged, but was not registered by British authorities "[f]or some reason".^[99] On 1 February 2018, before any further court proceedings, Feeney announced his resignation from the House of Representatives, and confirmed that he had been unable to find documentation proving his renunciation of British citizenship.^[11]

On 23 February 2018, the Court held that Fenney had been ineligible to be elected by virtue of s.44(i) and that the vacancy is to be filled by a by-election.^[220] A by-election had already been called for 17 March 2018. Feeney did not re-contest the seat in the by-election, which was contested by Ged Kearney for the Labor party. Labor only narrowly won the suburban Melbourne electorate of Batman with Feeney in 2016, facing strong competition and losing the first-preference vote to the Greens' Alex Bhathal. The Greens announced on the same day as Feeney's resignation that Bhathal would run again in the Batman by-election.^[221][100] Kearney won the 2018 by-election with a 3.6% swing towards Labor, in the absence of a Liberal candidate.

Katy Gallagher

Labor Senator Katy Gallagher's mother was a British citizen born in Ecuador to British parents.^[222] Gallagher first entered Parliament on 25 March 2015, following a casual Senate vacancy for the Australian Capital Territory.^[223] She filed UK citizenship renunciation papers with the UK Home Office on 20 April 2016, in the lead-up to the federal election in 2016, which took place on 2 July. The UK Home Office accepted her payment as part of the application on 6 May; however, on 1 July, it requested original copies of her birth certificate and her parents’ marriage certificate as part of her renunciation, which Gallagher provided on 20 July. The renunciation of her British citizenship was effective on 16 August 2016, after the federal election.^[224] On 6 December 2017, at Gallagher's request the Senate referred her case to the High Court.^[93]

The Senate referred Gallagher's case to the High Court as the Court of Disputed Returns. Her case was considered along with Feeney's during a directions hearing on 19 January 2018.^[98][225] The Attorney-General argued that Gallagher had not taken all reasonable steps to renounce her citizenship.^[226] On 9 May 2018, the Court unanimously found Gallagher to have been ineligible.^[107][227] Her disqualification triggered resignations of four other MPs in similar situations, who also attempted to renounce their British citizenships before the election, but were still effectively British citizens at the date of nominations. She was replaced by union official David Smith on 23 May 2018.^[228]

Gallagher's declaration that she did not hold foreign citizenship when the Australian Capital Territory Legislative Assembly nominated her to a casual vacancy in the Senate in 2015 prompted an Assembly inquiry into its Senate nomination processes, announced on 30 November 2017.^[229][230]

Justine Keay

Labor MP Justine Keay was born in Australia with British citizenship. She had been preselected by the Labor Party in 2015, but completed the UK Home Office's citizenship renunciation form on 9 May 2016, the day when the Parliament was dissolved for the 2016 federal election. The form was received by the Home Office on 31 May. Nominations for the election closed on 9 June and the election took place on 2 July. She received the British government's declaration of the renunciation on 8 July and the renunciation was registered on 11 July.^[231][232]

A legal opinion by David Bennett QC, a former Commonwealth Solicitor-General, commissioned by the Liberal Party, is that Keay, along with Susan Lamb and Rebekha Sharkie, were ineligible under the High Court ruling because they were British citizens at nomination date.^[233][234] Keay claims that she had taken "all reasonable steps" for renunciation.^[235][236] After Gallagher was disqualified, Keay announced her resignation,^[108] triggering a by-election in Braddon.

Susan Lamb

Labor MP Susan Lamb, born in Australia, had received advice that she may be a British citizen by descent through her late father. On 23 May 2016, two weeks before close of nominations for the 2016 federal election, she filed a renunciation form with the UK Home Office.^[237] However, Lamb's renunciation form was refused by UK authorities as they were not satisfied that she was in fact a British citizen, and instead requested further documents as proof. Lamb claimed to have fulfilled all the requirements of section 44(i) as she believed she had taken all reasonable steps to renounce her citizenship – if it were the case that she was a British citizen – as she was unable to provide any further documents; she said she was estranged from her mother and that her father had passed away.^[238] After Gallagher was disqualified, Lamb announced her resignation,^[108] triggering a by-election in Longman.

Rebekha Sharkie

NXT MP Rebekha Sharkie stated in July 2017 that she had renounced her UK citizenship prior to the election.^[239] She began the process to renounce her British citizenship on 19 April 2016, before the close of nominations, but the renunciation had not been registered by UK Home Office until 29 June, 20 days after nominations closed, although prior to the election.

Sharkie said that in November 2017 Turnbull had advised her that a reference to the High Court might be required in relation to her possible dual-citizenship status at the close of nominations. She argues that she has taken "all steps that were required by the UK to renounce any entitlement to UK citizenship, that were within my power to do so". It has also been suggested that she may be a citizen of the United States.^[240] After Gallagher was disqualified, Sharkie announced her resignation,^[108] triggering a by-election in Mayo.

Josh Wilson

Labor MP Josh Wilson applied to renounce his British citizenship on 13 May 2016, the day after his unexpected endorsement as a candidate for the 2016 election, nominations for which closed on 9 June. The renunciation was registered and effective on 24 June.^[90][241] After Gallagher was disqualified, Wilson announced his resignation,^[108] triggering a by-election in Fremantle.

Greek citizenship concerns

It has been suggested that three Liberal parliamentarians—Julia Banks MP,^[242][243] Alex Hawke MP,^[244][245] and Senator Arthur Sinodinos^[246]—could hold Greek citizenship by descent from a Greek parent or parents.^[243] Both Greece and Australia permit dual citizenship.^[247] However, all three have entered on the Citizenship Register statements from the Greek Embassy that, since their births were not registered in Greece, they are not Greek citizens; they also refer to legal advice that they are not Greek citizens nor entitled to the rights or privileges of Greek citizenship.^[90][89]

Other foreign allegiance concerns

Katy Gallagher has also faced suggestions from The Daily Telegraph that she may be an Ecuadorian citizen, due to the 2008 Ecuadorian constitution which established the right of citizenship for anyone born in Ecuador, as well as their descendants even if born abroad.^[248][249] Gallagher has stated that the change in law in 2008 had no effect on her, as the change does not apply retrospectively to the time of her mother's birth.^[250] The ALP has said it has obtained advice from an Ecuadorian legal expert and an Australian constitutional lawyer which advised Gallagher is not an Ecuadorian citizen.^[251] Because she has been found ineligible on the ground of her British citizenship at the time of nomination,^[107] although she has since renounced it, the question of Ecuadorian citizenship remains relevant only if she wishes to re-enter the Commonwealth Parliament.

On 2 November 2017, questions were raised by The Australian concerning the possibility that Liberal MP and Minister Josh Frydenberg could be a citizen of Hungary under a Hungarian law designed to prevent statelessness caused during World War II. The report claimed that the retrospective law provided that anyone who had been born within Hungary in the period 1941 to 1945 automatically became a Hungarian citizen, and citizenship in Hungary is passed down by birth right. As his mother was born in Hungary in 1943, an argument was raised that this meant Frydenberg held Hungarian citizenship.^[252] Frydenberg said that it was absurd to suggest he had involuntarily acquired Hungarian citizenship as, when his mother and other family members entered Australia in 1950, they were stateless survivors of the Holocaust.^[253][254] Prime Minister Turnbull and Attorney-General Brandis condemned the calls as witch hunts.^[255][256] Hungarian citizenship experts have since stated that such citizenship is not automatically conferred and can be restored only if the individual takes action that is "more than a formality".^[257]

On 11 November 2017, it was suggested that Liberal MP Nola Marino, Chief Government Whip in the House of Representatives, may be a citizen of Italy through marriage to an Italian citizen at a time when Italian law automatically conferred citizenship through marriage, unless her husband had renounced his Italian citizenship on becoming a naturalised Australian prior their marriage in Australia in 1972. Her husband was born in Italy in 1950, and came to Australia the next year. She might also be a citizen of the United States through her father, born in New York. She has denied being anything but an Australian, but has not provided details.^[258]

In his Citizenship Register entry,^[89] Senator Cory Bernardi states that his father and his father's parents were born in Italy. He adds that, when a child, he had asked an Italian consulate whether he was eligible for Italian citizenship and had been told that he was not, because at the time of his birth his father had been solely Australian; but no documentation of this is provided. Bernardi provides a copy of an application in 2006 to renounce Irish citizenship, which he later says he had acquired through marriage, but he has not provided a copy of a response to the application from Irish authorities.^[259][260]

Jason Falinski MP has stated a complex heritage, which he claims does not involve current foreign citizenship.^[90] However, his account has been questioned, with The Daily Telegraph reporting that documents from the National Archive of Australia show Falinski's paternal grandparents as being married a year prior to his father's birth – contradicting his statement in the Citizenship Register that his father was born out of wedlock. In response to these suggestions, Falinski said that his grandparents and father would have nonetheless lost their Polish citizenships per Polish law at the time upon emigrating to Australia even if this were the case.^[261]

It was suggested in May 2018 that Labor MP Anne Aly, born in Egypt, might still have Egyptian citizenship. She then obtained confirmation from the Egyptian embassy in Australia that she had forfeited her Egyptian citizenship upon acquiring Australian citizenship on 6 May 2016, two days before the federal election of 2016 was called.^[262]

Citizenship statements by other MPs and Senators

Prior to the implementation of the parliamentary Citizenship Register, several other MPs and Senators who were born outside Australia or are known to have at least one foreign-born parent have made statements clarifying that they were not dual citizens at the time of nominating as a candidate.

Among the highest-profile former British citizens were former prime minister Tony Abbott and incumbent opposition leader Bill Shorten, who released letters from UK Visas and Immigration and the UK Border Agency respectively to confirm that they renounced their British citizenship before being elected.^{[239][263][264][265]} British-born politicians who stated they had previously renounced their British citizenship included Labor MP Brian Mitchell, Greens Senator Nick McKim,^[266] Liberal MP Paul Fletcher, CLP Senator Nigel Scullion, and Greens Senator Jordon Steele-John.^{[267][268][239]} One Nation Senator Pauline Hanson^[25] and Liberal MP Ann Sudmalis denied claims that they were British citizens by descent.^{[269][270][271][265]}

Parliamentarians who were born overseas or descended from foreign nationals made similar statements, including those who were accused of being citizens of: Italy (Greens Senator Richard Di Natale and Labor MP Tony Zappia);^[266][272] Singapore (Liberal MP Ian Goodenough and Greens Senator Peter Whish-Wilson); Belgium (Liberal frontbencher Mathias Cormann);^[268] Greece (Labor MP Maria Vamvakinou); Iran (Labor Senator Sam Dastyari); Malaysia (Labor frontbencher Penny Wong); New Zealand (Senator Rex Patrick);^[273] Slovenia (Labor's Deputy Opposition Leader Tanya Plibersek); and the United States (NXT MP Rebekha Sharkie).^{[274][240][239][264]} Senator Derryn Hinch did confirm that he is entitled to a pension through US Social Security,^[275] but stated on 2 September 2017 that he would not seek a reference since the Attorney-General had advised him that he was not in breach.^[276]
