Can decisions made by former deputy prime minister Barnaby Joyce while he was invalidly in parliament be challenged?
Laws passed by MPs while under a citizenship cloud are unlikely to be contested; decisions made by ministers after doubts about their dual citizenship was announced are more complicated matters.
George Brandis said the government was looking very carefully at the question of the validity of the former ministers’ decisions.
The opposition says at least 20 executive decisions and 47 ministerial announcements made by Barnaby Joyce could be open to challenge.
The High Court has ruled Scott Ludlam, Larissa Waters, Fiona Nash, Barnaby Joyce and Malcolm Roberts ineligible to have stood for parliament at the 2016 election.
The question will now be whether Section 44 of the Constitution needs reform to enable dual citizens who may have a lot to offer to become MPs.
The High Court declared Barnaby Joyce ineligible to sit in parliament.
The High Court was unanimous on its decision in all the cases, with the eligibility of five MPs rejected and two upheld.
