I am reluctant.
What I am trying to avoid in this committee are unforeseen adverse effects. I think that if the bells start to ring and the meeting has not yet begun, it is the responsibility of the chair to reconvene the meeting sometime after the vote the bells signal has taken place.
The possibility of beginning the meeting while the bells are ringing may raise various problems, and different strategic tactics could be used by certain parties, subsequently. I would have trouble accepting an interpretation according to which the chair would be authorized to begin a meeting while the bells are still ringing.
Consequently, I do not agree, not necessarily for reasons I can explain right now, but because of the potential use of that provision as a probable loophole later.
