That's not an appropriate way to address a point of order. I don't believe it was unparliamentary, but it was completely out of order to use a point of order for that. It is not up to me to rule which interjections are disorderly or not; they are always disorderly. Interjections are not a method for holding a minister accountable—questions and answers are. I ask senators to respect that and to hear the minister in silence.
