Senator RUSTON (South Australia—Deputy Government Whip in the Senate) (14:43): I have a supplementary question. Will the minister explain to the Senate the need for compulsory powers to obtain evidence and information in a construction industry infected by a culture of fear and silence? Senator Moore: I rise on a point of order. The PRESIDENT: I probably do not need a point of order on this, Senator Moore. The question is now referring to provisions of the bill. Opposition senators interjecting— The PRESIDENT: Order! We are in very difficult territory, because the standing orders do provide that debate cannot be anticipated. I interpreted from the question that that would infringe the standing orders. I invite the questioner, Senator Ruston, to ask the question again—probably in broader terms.
