Mr PASIN (Barker) (14:27): My question is to the Treasurer. I refer the Treasurer to this email from the chief executive of— Opposition members interjecting— The SPEAKER: The member for Barker is not using props. Mr PASIN: No. It is a document. The SPEAKER: Just put it down. The member for Barker is a new member asking an early question. Opposition members interjecting— The SPEAKER: Those on my left will desist. The member for Barker has the call. Mr PASIN: Thank you, Madam Speaker. My question is to the Treasurer. I refer the Treasurer to correspondence received by me from the chief executive of the Master Butchers Cooperative, Mr Warren McLean, saying that the carbon tax has cost his business more than $330,000 in higher electricity and gas costs. Treasurer, what is the government doing to reduce the electricity for families and businesses? Ms Owens interjecting— Mr Dreyfus interjecting— The SPEAKER: The member for Parramatta and the member for Isaacs are warned! Mr Fitzgibbon: Madam Speaker, I rise on a point of order. I refer you again to standing order 100(d), which is referred to again in House of Representatives Practice. I have raised this with you before. This is the fourth occasion this week when members on the government side have asked questions using names and, in this case, using a document that has not been authenticated. I ask you to rule the question out of order. The SPEAKER: No, I will not be ruling it out of order. Under the standing orders the letter was necessary to make sense of the question and it was authenticated. We went through this with the Deputy Leader of the Opposition earlier this week. I call the honourable the Treasurer. Mr Fitzgibbon: Madam Speaker— The SPEAKER: You have had your point of order. The Treasurer has the call.
