The Acting Deputy President:

Just a moment, Senator Macdonald. Senator Brown, I have made it clear to you that I will provide you with the protection of the chair when you need it. It is my judgment that you had not been in need of the protection of the chair, but, if the senators on my left become unusually or extraordinarily rowdy, I will provide you with the protection you need. So, in those circumstances, Senator Brown, perhaps you would be good enough to withdraw your reference to the chair and we can move ahead with the debate.
