Provisions like this are inserted to facilitate the work of the committee. The government may have some concerns that it would be used for some ulterior motive here.
An example of a motion that could pop up, which you'd want to deal with quickly if there was a strong consensus, would be concerning a witness who didn't show up. The committee would want to give an order. You'd want to move a motion. The clock is running on this committee. You don't want to wait for a long period before you respond to that. During clause-by-clause consideration, if you had a very strong consensus to make an amendment, whether it were technical or otherwise, based on this, you wouldn't be able to move that motion. You'd have to send the bill back to the House without an appropriate amendment that had a strong consensus behind it.
I don't see any problem with the current wording. Rarely have I seen it abused. I can't recall a case. I can appreciate the government's caution here, but whether it's 24 hours' or 48 hours' notice, it really doesn't make too much difference.
Has somebody moved 24 hours' notice?
