Mr DUTTON (Dickson—Leader of the Opposition) (14:27): My question is to the Minister for Indigenous Australians. I refer to the minister's previous answer. Minister, can the parliament really override the provisions of the Constitution? Honourable members interjecting— Mr Dreyfus: What a ridiculous question. What an absurd question. You're not fit to be the Leader of the Opposition. The SPEAKER: The Attorney-General will cease interjecting, as will the member for Deakin and the deputy leader. Anyone else down there as well can zip it. Mr Burke: On a point of order, Mr Speaker: in the ordinary course, something about the Constitution would be directed to the Attorney-General and it would also be out of order if it were a legal opinion, and I'm not sure what else this question could be considered as. The SPEAKER: The way that it's stated it's possibly seeking legal opinion, but I want to hear from the Manager of Opposition Business. Mr Fletcher: It's well accepted in this parliament that questions can be asked seeking clarification of what has been said by, in this case, a minister in a previous answer. In this case it's the answer she's just given. The SPEAKER: That's different to what the opposition leader did ask. I'm going to allow the question, if he could rephrase it to make sure it is following what the manager just advised. Mr DUTTON: My question is to the Minister for Indigenous Australians. I refer to the minister's previous answer. Can the minister confirm her advice, in her previous answer, that the parliament can override the provisions of the Constitution? The SPEAKER: I'll allow the question. Ms Plibersek: It's not her advice! The SPEAKER: Order! The Minister for the Environment and Water will cease giving comment each time a minister approaches the dispatch box.
