An hon. member suggests caning but that has not been in our lexicon of punishments. However, there is the fact that people can be called to the bar of the House and chastised for contempt.
Of course the ad hoc group had no such powers and so it was perfectly legitimate in my opinion for some to say, “No, you may not appear”, and for people to refuse to appear either on instructions or because they themselves chose not to appear, because the ad hoc group had no power to compel attendance.
In the circumstances, I am unable to find there was any breach of the hon. member's privileges. I would urge him in future to look to the other options that are available to him and to all hon. members in asserting their claims, by going through the proper channel of a parliamentary committee with all the wondrous powers that each of those committees enjoys.
