Senator KROGER: by leave—I move: That leave of absence be granted to Senator Johnston for 9 November 2011, on account of parliamentary business. Question agreed to. Senator Bob Brown: Mr Deputy President, a point of order: we assented to the motion that Senator Kroger moved; however, I think when there is a parliamentary reason for missing parliament it might be better if that reason were given to the Senate when such motions are brought forward. The DEPUTY PRESIDENT: Senator Brown, that is all that is required under the standing orders. A reason must be given and that reason has been given—it is for parliamentary reasons. Senator Bob Brown: I agree that the reason has been given, but it is not an explanation as to what the parliamentary reason is. I am suggesting it would be a courtesy to have the chamber acquainted with the specific reason for the absence. The DEPUTY PRESIDENT: The matter is in conformity with the standing orders. However, if you wish to raise the matter with the Procedure Committee, that would be a good avenue for it to be progressed. Senator Bob Brown: I am raising it with you. The DEPUTY PRESIDENT: The matter is in conformity with the standing orders.
