I will read part of the ruling that was given in the House not that long ago. House of Commons Procedure and Practice, third edition, has the following, on page 620:
Although the Chair has been known to show considerable leeway at times in recent years, it is generally understood that disrespectful reflections on Parliament as a whole, or on the House or the Senate individually, are not permitted...and it is out of order to question a Senator’s integrity
I would again ask members to please be mindful of that.
