I want to reinforce one point. I have challenged the chair in previous committee business in this Parliament, and one would hope that if your colleagues believe the chair has ruled something inadmissible which is not, the natural alternative would be to go to their peers on the committee, because we are masters of own destinies. The other alternative, as suggested, is to bring it up with the Speaker and to appeal to the Speaker at report stage. There are mechanisms to make sure that these efforts are made.
When we have witnesses come forward, I believe strongly that they should be able to give their opinions. It may not always be directly related to the business before the committee, but as parliamentarians we always benefit from hearing different voices, even if we disagree with them, and even when we agree with them but it's not on the subject at hand.
I appreciate all the contributions today, and I look forward to continuing this.
