I realize I haven't heard all the points of order here, but am I correct that you're suggesting that the only thing one can talk about is whether or not it should be 30 sitting days or 40 or 50 or 60?
If the issue is the last sentence of the motion and not the entire motion, surely you can't just say yes or no. You can't just say you agree with an extension or you don't agree with an extension. You have to say the argument in one direction or the other of agreeing with an extension must include the reason why you think the committee should request or not request this extension. That has to be a part of the debate over whether or not...and even if you did restrict it to the last sentence, the debate about whether or not that should be accepted has to be about why it should be requested or why it should not be requested or why you would be against it.
So I can't conceive that you've suggested that you can only say yes or no. There has to be the rationale for one supporting or not supporting that motion. Have I got that wrong, or are you saying you can only talk about those six or eight words?
