On the point of order, whilst I may not agree with much of what the senator is saying at the moment, there has been a tradition in this place. I've heard many, many times senators from the opposition in particular being given a fair degree of latitude on debates of legislation. That has been the practice in this place. As much as I may not agree with Senator Roberts on much of what he was saying just then, often debate in this place goes a fair way from the absolute substance of every bill that we debate.
