In the case you are referring to, the motion comes in about 36 hours ahead of time. Suppose the meeting were scheduled for Thursday and the notice of motion is received at 6:00 p.m. on Tuesday.
If the motion is submitted before 6:00 p.m. that day, it is considered to be the first 24-hour period. That is precisely how it works. According to our procedures, if a committee member were to submit a motion that does not deal with business under consideration and if the member were to submit it before 6:00 p.m. on the Tuesday, we could debate it on Thursday.
