I've just had some advice from the Clerk. Senator Whitten, the remarks in relation to what a senator was wearing are not in breach of the standing orders. I would ask that you keep your commentary in relation to other senators in this place in a parliamentary, safe way, in the goodwill of this chamber, but my ruling is that it is not impugning a senator. Please take your seat, Senator Shoebridge. I have ruled already on your point of order.
