Somebody should have run a fact-checker over Reelya's statements (or those of the article that inspired them...). I had it clearer a few months ago when I looked into it but to clear up a few points:
- Dual citizenship has been acknowledged for much longer than going back to 2002. I'm not sure how much longer but definitely earlier than 1992 (Sykes vs. Cleary) when there was a previous High Court ruling which involved section 44 of the constitution where both parties were understood as having dual citizenship.
- Part of the ruling of the High Court in the above case was that candidates must take "all reasonable steps" to rid themselves of foreign allegiance (read citizenship in current context) precisely to avoid the situtation of a foreign power holding Australia political hostage by granting citizenship to candidates/representatives. If they have made an honest attempt to do so and cannot they are still eligible to stand. This was reiterated in the more recent ruling.
- More difficult is that being unaware of dual allegiance does indeed invalidate one from standing. (So theoretically Turnbull could be in breach of the constitution if Putin has granted him Russian citizenship without him knowing...!)
- There has been an awareness of these issues for decades in Australian politics and the major parties (aka Labor and Liberal) have employed people to carry out citizenship checks in this regard. This is the reason the current 'crisis' hit the minor parties significantly more seriously since they are not such heavy-weight corporations with similar employees.
Most of the above statements are supported by the comments of Antony Green, (one of?) the most astute Australian electoral analyst who works for the ABC (think aussie version of BBC). One article for reference:
http://www.abc.net.au/news/2017-07-25/antony-green-high-courts-question-after-matt-canavan-resignation/8742912 which was published before the recent high court judgement. A search would probably turn up more and I remember an in-depth discussion on his blog as the events were unfolding - not sure if it would still be accessible.
Basically while acknowledging some of the historical problem, this has been bubbling away for some decades now and many people have been aware of it. In fact pretty much all of the representatives affected recently have either not known about their dual allegiances, or claimed not to.
The recent debacle was triggered by a lawyer in West Australia who had been digging around (unsuccessfully) for dirt on the ineligibility of Julia Gillard and Tony Abbot back in 2011.
http://www.abc.net.au/news/2017-11-16/john-cameron-says-labor-liberals-colluded-over-citizenship/9157920 He found out Ludlum was a dual citizen and brought it to his attention. Ludlum, who claims not to have known, resigned pretty much immediately (I presume after fact-checking). If memory serves Waters resigned the next day after Ludlum's shock resignation brought on a bout of fact-checking, at least amongst the Greens. I think all other 'offenders' disputed their status and went to court - some lost and some won.
As for constitutional reform the gist of it is that it is difficult, might very well fail, and is (said to be) being looked into by the government. A decent recent article that covers most of the issues:
http://www.abc.net.au/news/2017-10-28/what-does-the-high-court-decision-mean-for-dual-citizens/9094014 So amusement at the blue sky speculation aside I am relatively surprised at the general ignorance displayed, by the aussie crowd in particular. Not that that amounts to anything really...
