Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:15): Senator Di Natale, it's a good question. Let me address it. I think the principle that I referred to last week is a good principle. It is a good principle. Senator Di Natale, your former colleagues, Scott Ludlam and Larissa Waters, did the right thing. They may have resigned prematurely, but they certainly did the right thing in freely and without any pressure disclosing that they felt that they had a constitutional issue with section 44, just as Senator Canavan, Mr Joyce and Senator Roberts did the right thing by freely disclosing that they felt that they may have a constitutional problem under section 44. Now, it's certainly the government's view, based on Solicitor-General advice, that Senator Canavan and Mr Joyce are likely to be found by the High Court not to be disqualified in these circumstances by section 44. The PRESIDENT: Order! A point of order, Senator Di Natale? Senator Di Natale: Point of order on relevance. I made it very clear in my question that the Attorney-General either needed to provide evidence or indicate what has changed since he made his speech last week. I draw your attention to the question. The PRESIDENT: Thank you, Senator Di Natale. I will remind the Attorney-General of the question. Senator BRANDIS: Senator Di Natale, I have already told you that that remains my view. Nevertheless, it does depend, for it to operate, on a level of integrity by members of parliament—integrity that was, let me acknowledge, shown by Scott Ludlam and Larissa Waters, and integrity that was shown by Mr Joyce, Senator Canavan and Senator Roberts. What we don't have is the same level of integrity shown by members of the Australian Labor Party. Two days ago, the Prime Minister wrote to Mr Shorten and invited him to nominate any members of the Australian Labor Party about whom he had a level of concern, and Mr Shorten wrote straight back to the Prime Minister and indicated that he wasn't interested in participating in that process. Where there are levels of concern— (Time expired) The PRESIDENT: Senator Di Natale, a supplementary question?
