Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:50): I will not dignify that disgusting question with an answer. Honourable senators interjecting— The PRESIDENT: Order! And order on my right—how can I deal with interjections when I cannot hear them because of the interjections close to me? Senator Wong, do you have a point of order? Senator Wong: Yes, I do. They should withdraw calling Senator Cameron a grub. It was done repeatedly. Mr President, in question time you do have to protect senators to some extent. Honourable senators interjecting— The PRESIDENT: Order! If any senator used those words I would expect that senator to withdraw. I did not personally hear them. Senator O'Sullivan: I withdraw that you are a grub. The PRESIDENT: Senator O'Sullivan, could I ask you to withdraw, and do not repeat the phrase. Senator O'SULLIVAN: I withdraw. Senator Ian Macdonald: If 'grub' is unparliamentary, I did use that against Senator Cameron, and I withdraw. The PRESIDENT: Order! I remind senators that it is not so much the word that is used; it is also the context in which it is used. Honourable senators interjecting— The PRESIDENT: Order! Senator McGrath. Senator McGrath: I withdraw the use of 'grub'. The PRESIDENT: Thank you, Senator McGrath. Senator Nash. Senator Nash: I also withdraw the use of 'grub'. The PRESIDENT: Thank you. Senator Scullion. Senator Scullion: I withdraw, Mr President. The PRESIDENT: Thank you. Senator Williams. Senator Williams: I withdraw, Mr President. The PRESIDENT: Senator Hume. Senator Hume: I withdraw too, Mr President. The PRESIDENT: Thank you, Senator Hume. Senator Cameron, a final supplementary question. Honourable senators interjecting— The PRESIDENT: Order on both sides! Senator Ian Macdonald: What a disgusting excuse for a human being!
