Okay.
Perhaps all of you could turn to page 622 in your O'Brien and Bosc, chapter 13, Rules of Order and Decorum. Under the subtitle “Repetition”, it says the following:
Repetition is prohibited in order to safeguard the right of the House to arrive at a decision and to make efficient use of its time. Although the principle is clear and sensible, it has not always been easy to apply [204] and the Speaker enjoys considerable discretion in this regard. The Chair can curtail prolonged debate by limiting Members’ speeches to points which have not already been made.
That's as it applies to the House.
So as long as Mr. Warawa is referencing a new brief, or context from one of the submissions received from a witness on a specific point, I'll allow it, but I will not allow the same point to be made over and over again out of the same brief or from the same witness.
