Senator GEORGES (QUEENSLAND) - I direct a question to the Leader of the Government in the Senate. Since he is not prepared to deal with the fleas, perhaps he is prepared to deal with the elephant itself. Does he still agree that, and I quote him, 'the Senate has an obligation to uncover the truth despite the objection of the Government' and that the Senate has done nothing more than attempt to fulfill that obligation'? I refer to Senator Button's question today. Is the Leader of the Government in the Senate now erecting a barrier and, again I use his own words, 'a wall of silence' every time he is asked to answer certain questions? Will he not agree again with the statement that he made in 1975 against the previous Government when he said that 'refusal of information is the first step towards tyranny' and that a people denied information cannot judge the facts '? If he is not prepared to answer questions in this place and so give the facts, would it not be a highly desirable action on his part to withdraw from the Senate until the Royal Commission had decided whether or not his statements contain assumptions or facts?
