It depends on whom you ask. Some committees do things one way; some do things differently.
The other question with this motion is that the 48-hour period is interpreted as two sleeps and not exactly 48 hours. If I receive a notice of motion between five o'clock and six o'clock, I'm not in the office; I will have received it, but I can only send it out the next day. That's one thing. The other thing is it all depends on whom you ask.
It's really up to you to decide as a committee how you want to interpret it and how you want me to deal with these motions.
