My question is to the Prime Minister. I refer to revelations in the media that the Minister for Home Affairs' ability to cancel criminal visas is being challenged in the Federal Court because of serious doubts about his eligibility under section 44 of the Constitution. Given that all sides of politics support cancelling the visas of dangerous criminals and deporting them, will the Prime Minister now refer the Minister for Home Affairs to the High Court to remove any doubt over the minister's decisions?
