Mr BUTLER (Hindmarsh—Deputy Manager of Opposition Business) (14:48): My question is to the Minister for Emissions Reduction and Energy. Last year, the House was assured that the minister would fully cooperate with the New South Wales Police Force's Strike Force Garrad investigation, but the New South Wales police have given evidence to the New South Wales parliament that the minister rejected an interview request. Why did the minister promise the House that he would cooperate with the investigation but then refuse to be interviewed by the New South Wales police? The SPEAKER: Just before I call the minister, perhaps I'll hear from the Leader of the House. I just need to be convinced— Honourable members interjecting— The SPEAKER: Alright—I can rule on it whenever you're ready. I have made the point that when it comes to ministerial responsibilities, certainly, questions can't be asked about policy areas for which the minister is not responsible. They can be asked about a minister's previous answer. But, as I've made clear, that's been referring to the minister's previous answer. I'll hear from the Leader of the House on it—sorry, from the Manager of Opposition Business on it. Mr Burke: Mr Speaker, while it doesn't use the term 'answer' it refers to an assurance that the minister gave to the House. Ministers have a responsibility to the House when they provide that information, and for us to be able to test— The SPEAKER: Yes, that's okay. I'll call the minister.
