The High Court has ruled that Deputy Prime Minister Barnaby Joyce was indeed a dual citizen when he was elected to office, and has along with four other members of the "Citizenship Seven" been ruled ineligible. 

"I was always apprehensive," said Mr. Joyce to constituents in Tamworth, NSW following the verdict.  "I was always prepared for this outcome," he said as quoted by Fairfax Media. 

"I had no reason to believe I was a citizen of any other country but Australia.  I was born just there.  Just there.  I grew up over there," he told reporters on a scenic outlook.  "And I served in our nation's Defence Forces. Had no reason to believe I was anything but Australian," Mr. Joyce said while wearing the most-Australian-looking hat possible.  Honestly, he couldn't have been more Australian if he had said that while spreading Vegemite on a Wallaby with a boomerang.

Joyce is stepping down from his ministerial position and will have to fight a byelection, probably in December.  This means when Parliament returns on 27 November 27, the Turnbull government will have lost its one seat majority in the House of Representatives.  

Deputy opposition leader Tanya Plibersek said, "We now have a minority government with a hung parliament because Barnaby Joyce broke the law." She also recalled Prime Minister Malcolm Turnbull's ill-fated prediction that the High Court would rule in favor of Joyce: "We have a Prime Minister who has made these bad judgment calls again and again and again."

Labor leader Bill Shorten was heading overseas, but managed to slam the PM via Twitter: "Turnbull should've stood him aside, terrible judgement once again."

Senator Fiona Nash has also been ruled ineligible, making her former deputy leader of the coalition in the Senate.  

The court also found One Nation's Malcolm Roberts, who left a comical electronic trail in checking his citizenship status with the UK, wasn't validly elected; he refused to apologize.

Former Greens senators Scott Ludlam and Larissa Water, who had the foresight to step down once this controversy bubbled up, were also ruled ineligible.

Matt Canavan, whose mother signed him up for Italian citizenship without his knowledge, was ruled eligible; so was Senator Nick Xenophon, who is standing down anyway and has been tipped in recent polling as the front-runner for South Australia's next Premier.
