Barnaby Joyce, Australia's Deputy Prime Minister, told the country's Parliament on Monday he had chose to refer himself to the High Court after the New Zealand High Commission told him he could be a New Zealand citizen by descent through his father.
Yesterday, the Nationals leader discovered he was also was in breach of Australian law, holding dual Australian-New Zealand citizenship, which section 44 of the Constitution forbids.
The court listing came as the row over Mr Joyce's citizenship threatened not only the Turnbull government but relations with New Zealand.
Malcolm Turnbull, the prime minister, accused Bill Shorten, the opposition Labor leader, of "conspiring with a foreign power" to bring down his administration during angry scenes in parliament.
"I had no idea that it was going to have this particular impact on Australian domestic politics - had I known that, I probably wouldn't have because frankly I don't want to get involved in it".
Mr Hipkins claims he didn't know whether the staffer's question related to a specific person. "Australian media inquiries were", Dunne tweeted on Tuesday.
She met with Australia's high commissioner, its highest envoy in New Zealand, on Tuesday to voice her disappointment at Ms. Bishop's comments, and to say that the behavior of Mr. Hipkins, the New Zealand politician who raised the issue in Parliament, was unacceptable.
Australia's Turnbull government has been rocked by another day of drama over the dual citizenship fiasco, a diplomatic stoush with New Zealand and another Liberal MP facing questions over their eligibility for Parliament.
The High Court is now considering the technicalities of his case, along with the four others.
Both the Greens - which have lost two senators over dual citizenship dramas - and the Labor Party have called on Mr Joyce to resign as Deputy Prime Minister until the High Court rules on his case.

Waters has since renounced her Canadian citizenship.
New Zealand officials said queries from Australian journalists prompted last week's discovery about Joyce's status.
The country's Internal Affairs minister Peter Dunne said it was "utter nonsense" to suggest New Zealand's opposition party had triggered Joyce's problems.
Dual citizens are not allowed to run for public office under Australia's constitution.
Unwittingly or not, he is a New Zealand citizen.
The ALP's involvement has angered Australian Foreign Minister Julie Bishop, who said she would have trouble trusting a New Zealand Labour should they form government.
"We go through parents and we go through grandparents and then a team of lawyers work with the candidates to make sure they have fulfilled the requirements of Section 44", he said.
Aussie Foreign Minister Julie Bishop says Labour has been used by the Australian Labor Party to seek to undermine the Australian Government.
