I don't see this as a NDP/Liberal issue. If the Speaker is going to make changes to the way business is conducted and not consult the members, it's a problem. I wonder if NDP has thought about the precedent that will now stand, if not challenged by the NDP,  when they are back in opposition. If a new Liberal speaker makes further changes limiting the opposition I supposed the NDP opposition (when it occurs) will just nod and say nothing.
