Amid the daily dramas and momentous impact of the ongoing coronavirus pandemic, it’s easy to forget that, just four years ago, Australia was enduring a very different – and much less serious – kind of political crisis. In July 2017, the Australian Greens’ Scott Ludlam resigned from the Senate, having been advised that his failure to renounce his long-dormant New Zealand citizenship meant that he was a dual citizen, and in breach of section 44 of the Constitution. This kicked off a farcical procession of resignations, High Court referrals, by-elections, and countbacks. This ultimately resulted in fifteen MHRs and senators from across the political spectrum being ruled ineligible to sit in the federal parliament.
