In an exchange in New Zealand's Parliament from 2017, the following record has been kept:
Hon STEVEN JOYCE: Grumpy old prick.
Grant Robertson: I raise a point of order, Mr Speaker. I know there is a robust exchange in the House, but the Minister of Finance did use an extremely unparliamentary term to describe the leader of New Zealand First.
Mr SPEAKER: I heard the interjection; I did not hear where it came from, but now that it has been identified, I require the Minister to stand, withdraw—[Interruption] Order! The member is not yet in this position; he might be at some stage in the future. I require the member to stand, withdraw, and apologise.
Hon STEVEN JOYCE: I withdraw and apologise.
Mr SPEAKER: Thank you.
So clearly the Speaker intervened in that case in response one MP calling another "grumpy old prick", and basically forced an apology.
Have there been any examples in which (extremely) unparliamentary language was not withdrawn and so has led to some other, more serious consequences?
