There are seven men and women who sit as the Full Court of the High Court in Canberra.
This week, they will decide the future of seven men and women who take their seats just up the hill in Parliament House.
The court has set aside three days from Tuesday to consider whether they breach Section 44 of the constitution, which disqualifies anyone holding an allegiance to any foreign country.
Barnaby Joyce (NZ), Matt Canavan (Italy), Nationals' deputy Fiona Nash (UK), former Greens Senator Larissa Waters (Canada),former One Nation Senator Malcolm Roberts (UK), former Greens Senator Scott Ludlam (New Zealand) and independent Senator Nick Xenophon (UK) are those 7 victims.
