Mr Deputy President, I'd like to seek your clarification—maybe you can come back to the chamber or have the President do it—in relation to the use of the word 'lie'. My understanding is that there hasn't been a ruling in this chamber against the use of just that word. Of course, under longstanding provisions, one shouldn't be accusing an individual, a member, a senator or anyone of any office of being a liar. But simply referring to a lie is not against the standing orders.
