SPEAKER: I want to thank the member for his suggestion. I think it is something which would be appropriate for the Standing Orders Committee to consider at the appropriate time. At the moment, there's not only the reference in Parliamentary Practice in New Zealand that the member has rightly drawn my attention to. In preparation for this, of course, it was part of the research, but I remember the Rt Hon David Carter referring to the quality of the judgment of Speaker Wall, and there is, at Speaker's ruling 120/2 a very clear ruling from Speaker Wall on that matter.
