The great saying of 2021 will be “you are muted”.
I take the view that this is an unnecessary motion. I haven't seen any example of this being of any difficulty in any committee I've sat on in the last year.
Also, I do take the view as espoused by Mr. Strahl that this may actually impact negatively on the rights of unilingual members who may want to move a motion and can function only in one official language. I think there are plenty of opportunities to address those limitations in the context of a committee.
