It is only courteous to be able to hear them. However, you will note that the motion authorizes the holding of meetings, the receiving of evidence, and the printing of evidence, but not the holding of votes, which is the protection for the committee.
Remarquez cependant que la motion autorise la tenue de réunions, l'audition de témoins et l'impression de témoignages, mais non la tenue de votes, ce qui constitue une protection pour le comité.
