This is interesting in the context of the ongoing dual citizenship debate in Australia. Many Australian MPs are taken on trips to Israel (purely in the line of business of course). The relevant part of our constitution is Section 44(i):
“Any person who – Is under any acknowledgment 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 a 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.”
This has led to several members of parliament having to resign for being (sometimes unknown to them) citizens of the UK, New Zealand, Italy and elsewhere.
It would be interesting to know how our High Court might interpret the signing of such a document . Does it constitute obedience to a foreign power? More broadly, anyone who has a right to citizenship of Israel (though not necessarily a citizen) presumably ought to have problems under this law, though no such case has been made public yet. There are several Jewish members of parliament some of whom -along with many non-Jewish members – are staunch supporters of Israel.
