We are absolutely opposed to the idea that even in theory the chair could call witnesses and bring three members of the government side to hear the witness and have the proceedings recorded as official evidence without any of the official opposition being there. That is, I think, against the spirit of our parliamentary system.
To say that one member of the opposition should be present is different from saying that everybody should have someone there. There is a role for the official opposition—or for the opposition, not even “official” opposition—to be present when a witness is being heard.
I think the motion should stand as is and that it's a mistake to amend it.
