Mr. Chair, I rather question your ruling, because Standing Order 119, which I just read out, doesn't say he has to be subbed in. It says that a member of the House, unless otherwise stated, should be allowed to speak.
I just read it out. It says:
Any Member of the House who is not a member of a standing, special or legislative committee, may, unless the House or the committee concerned otherwise orders, take part in the public proceedings of the committee, but may not vote or move any motion, nor be part of any quorum.
It doesn't say he has to be signed in. It just says that if he's a member of Parliament, he may participate.
