Leader of the House, Christopher Pyne says the government will refer Labor M-P Susan Lamb's case to the High Court if she doesn't step down from her Brisbane seat and do the right thing.
Mr Pyne says there's no way Ms Lamb can pretend she isn't a British citizen.
He's told the A-B-C, the Queensland M-P should resign.
"There's no need for Susan Lamb to be referred to the High Court. Susan Lamb is a U-K citizen. She has admitted it herself through her barristers' opinion. There's nothing for the High Court to find with Susan Lamb. Susan Lamb is a U-K citizen right now." Mr Pyne said.
